acpica-unix
-----------
This source release includes:
1) a cross-OS AML interpreter
This is intended to allow commercial and open source operating systems
to be enabled for ACPI. OS specific code is still needed, but the
AML interpreter should greatly improve the development speed of ACPI
support.
The AML interpreter source should be integrated into the kernel's
build process. We recommend establishing an automated method for
this, so later versions can also be incorporated easily. Please see
the documentation on the website for API and other implementation
information.
2) iasl, an ASL compiler/decompiler
iasl compiles ASL (ACPI Source Language) into AML (ACPI Machine
Language). This AML is suitable for inclusion as a DSDT in system
firmware. It also can disassemble AML, for debugging purposes.
To compile:
cd compiler
make
It has been compiled on Linux, but should easily port to other Unix
environments.
Run 'iasl -h' for more information, or download the binary version for
documentation in PDF format.
3) acpisrc, a source code conversion tool
acpisrc converts the standard form of the acpica source release (included
here) into a version that meets Linux coding guidelines. This consists
mainly of performing a series of string replacements and transformations
to the code.
To compile:
cd tools/acpisrc
make
It has been compiled on Linux, but should easily port to other Unix
environments.
4) acpibin, an AML file tool
acpibin compares AML files, dumps AML binary files to text files,
extracts binary AML from text files, and other AML file
manipulation.
To compile:
cd tools/acpibin
make
5) acpiexec, a user-space AML interpreter
acpiexec allows the loading of ACPI tables and execution of control
methods from user space. Useful for debugging AML code and testing
the AML interpreter.
To compile:
cd tools/acpiexec
make

----------------------------------------
28 May 2010. Summary of changes for version 20100528:
This release is available at www.acpica.org/downloads
Note: The ACPI 4.0a specification was released on April 5, 2010 and is
available at www.acpi.info. This is primarily an errata release.
1) ACPI CA Core Subsystem:
Undefined ACPI tables: We are looking for the definitions for the following
ACPI tables that have been seen in the field: ATKG, IEIT, GSCI.
Implemented support to enable multi-byte transfers for Embedded Controller
(EC) operation regions. Previously, the maximum data size passed to the EC
operation region handler was a single byte. There are often EC Fields larger
than one byte that need to be transferred, and it is useful for the EC driver
to lock these as a single transaction. This change enables single transfers
larger than 8 bits. This effectively changes the access to the EC space from
ByteAcc to AnyAcc, and will probably require changes to the host OS Embedded
Controller driver to enable 16/32/64/256-bit transfers in addition to 8-bit
transfers. Alexey Starikovskiy, Lin Ming
Implemented a performance enhancement for namespace search and access. This
change enhances the performance of namespace searches and walks by adding a
backpointer to the parent in each namespace node. On large namespaces, this
change can improve overall ACPI performance by up to 9X. Adding a pointer to
each namespace node increases the overall size of the internal namespace by
about 5%, since each namespace entry usually consists of both a namespace
node and an ACPI operand object. However, this is the first growth of the
namespace in ten years. ACPICA bugzilla 817. Alexey Starikovskiy.
Implemented a performance optimization that reduces the number of namespace
walks. On control method exit, only walk the namespace if the method is known
to have created namespace objects outside of its local scope. Previously, the
entire namespace was traversed on each control method exit. This change can
improve overall ACPI performance by up to 3X. Alexey Starikovskiy, Bob Moore.
Added support to truncate I/O addresses to 16 bits for Windows compatibility.
Some ASL code has been seen in the field that inadvertently has bits set
above bit 15. This feature is optional and is enabled if the BIOS requests
any Windows OSI strings. It can also be enabled by the host OS. Matthew
Garrett, Bob Moore.
Added support to limit the maximum time for the ASL Sleep() operator. To
prevent accidental deep sleeps, limit the maximum time that Sleep() will
actually sleep. Configurable, the default maximum is two seconds. ACPICA
bugzilla 854.
Added run-time validation support for the _WDG and_WED Microsoft predefined
methods. These objects are defined by "Windows Instrumentation", and are not
part of the ACPI spec. ACPICA BZ 860.
Expanded all statistic counters used during namespace and device
initialization from 16 to 32 bits in order to support very large namespaces.
Replaced all instances of %d in printf format specifiers with %u since nearly
all integers in ACPICA are unsigned.
Fixed the exception namestring for AE_WAKE_ONLY_GPE. Was incorrectly returned
as AE_NO_HANDLER.
Example Code and Data Size: These are the sizes for the OS-independent
acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The
debug version of the code includes the debug output trace mechanism and has a
much larger code and data size.

Non-Debug Version: 88.4K Code, 18.8K Data, 107.2K Total

Non-Debug Version: 88.3K Code, 18.8K Data, 107.1K Total
Debug Version: 164.1K Code, 51.5K Data, 215.6K Total
2) iASL Compiler/Disassembler and Tools:
iASL: Added compiler support for the _WDG and_WED Microsoft predefined
methods. These objects are defined by "Windows Instrumentation", and are not
part of the ACPI spec. ACPICA BZ 860.
AcpiExec: added option to disable the memory tracking mechanism. The -dt
option will disable the tracking mechanism, which improves performance
considerably.
AcpiExec: Restructured the command line options into -d (disable) and -e
(enable) options.
----------------------------------------
28 April 2010. Summary of changes for version 20100428:
1) ACPI CA Core Subsystem:
Implemented GPE support for dynamically loaded ACPI tables. For all GPEs,
including FADT-based and GPE Block Devices, execute any _PRW methods in the
new table, and process any _Lxx/_Exx GPE methods in the new table. Any
runtime GPE that is referenced by an _Lxx/_Exx method in the new table is
immediately enabled. Handles the FADT-defined GPEs as well as GPE Block
Devices. Provides compatibility with other ACPI implementations. Two new
files added, evgpeinit.c and evgpeutil.c. ACPICA BZ 833. Lin Ming, Bob Moore.
Fixed a regression introduced in version 20100331 within the table manager
where initial table loading could fail. This was introduced in the fix for
AcpiReallocateRootTable. Also, renamed some of fields in the table manager
data structures to clarify their meaning and use.
Fixed a possible allocation overrun during internal object copy in
AcpiUtCopySimpleObject. The original code did not correctly handle the case
where the object to be copied was a namespace node. Lin Ming. ACPICA BZ 847.
Updated the allocation dump routine, AcpiUtDumpAllocation and fixed a
possible access beyond end-of-allocation. Also, now fully validate descriptor
(size and type) before output. Lin Ming, Bob Moore. ACPICA BZ 847
Example Code and Data Size: These are the sizes for the OS-independent
acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The
debug version of the code includes the debug output trace mechanism and has a
much larger code and data size.

Non-Debug Version: 87.9K Code, 18.6K Data, 106.5K Total
Debug Version: 163.5K Code, 51.3K Data, 214.8K Total
Current Release:
Non-Debug Version: 88.4K Code, 18.8K Data, 107.2K Total
Debug Version: 164.2K Code, 51.5K Data, 215.7K Total
2) iASL Compiler/Disassembler and Tools:
iASL: Implemented Min/Max/Len/Gran validation for address resource
descriptors. This change implements validation for the address fields that
are common to all address-type resource descriptors. These checks are
implemented: Checks for valid Min/Max, length within the Min/Max window,
valid granularity, Min/Max a multiple of granularity, and _MIF/_MAF as per
table 6-40 in the ACPI 4.0a specification. Also split the large aslrestype1.c
and aslrestype2.c files into five new files. ACPICA BZ 840.
iASL: Added support for the _Wxx predefined names. This support was missing
and these names were not recognized by the compiler as valid predefined
names. ACPICA BZ 851.
iASL: Added an error for all predefined names that are defined to return no
value and thus must be implemented as Control Methods. These include all of
the _Lxx, _Exx, _Wxx, and _Qxx names, as well as some other miscellaneous
names such as _DIS, _INI, _IRC, _OFF, _ON, and _PSx. ACPICA BZ 850, 856.
iASL: Implemented the -ts option to emit hex AML data in ASL format, as an
ASL Buffer. Allows ACPI tables to be easily included within ASL files, to be
dynamically loaded via the Load() operator. Also cleaned up output for the -
ta and -tc options. ACPICA BZ 853.
Tests: Added a new file with examples of extended iASL error checking.
Demonstrates the advanced error checking ability of the iASL compiler.
Available at tests/misc/badcode.asl.
----------------------------------------
31 March 2010. Summary of changes for version 20100331:
1) ACPI CA Core Subsystem:
Completed a major update for the GPE support in order to improve support for
shared GPEs and to simplify both host OS and ACPICA code. Added a reference
count mechanism to support shared GPEs that require multiple device drivers.
Several external interfaces have changed. One external interface has been
removed. One new external interface was added. Most of the GPE external
interfaces now use the GPE spinlock instead of the events mutex (and the
Flags parameter for many GPE interfaces has been removed.) See the updated
ACPICA Programmer Reference for details. Matthew Garrett, Bob Moore, Rafael
Wysocki. ACPICA BZ 831.
Changed:
AcpiEnableGpe, AcpiDisableGpe, AcpiClearGpe, AcpiGetGpeStatus
Removed:
AcpiSetGpeType
New:
AcpiSetGpe
Implemented write support for DataTable operation regions. These regions are
defined via the DataTableRegion() operator. Previously, only read support was
implemented. The ACPI specification allows DataTableRegions to be read/write,
however.
Implemented a new subsystem option to force a copy of the DSDT to local
memory. Optionally copy the entire DSDT to local memory (instead of simply
mapping it.) There are some (albeit very rare) BIOSs that corrupt or replace
the original DSDT, creating the need for this option. Default is FALSE, do
not copy the DSDT.
Implemented detection of a corrupted or replaced DSDT. This change adds
support to detect a DSDT that has been corrupted and/or replaced from outside
the OS (by firmware). This is typically catastrophic for the system, but has
been seen on some machines. Once this problem has been detected, the DSDT
copy option can be enabled via system configuration. Lin Ming, Bob Moore.
Fixed two problems with AcpiReallocateRootTable during the root table copy.
When copying the root table to the new allocation, the length used was
incorrect. The new size was used instead of the current table size, meaning
too much data was copied. Also, the count of available slots for ACPI tables
was not set correctly. Alexey Starikovskiy, Bob Moore.
Example Code and Data Size: These are the sizes for the OS-independent
acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The
debug version of the code includes the debug output trace mechanism and has a
much larger code and data size.

2) iASL Compiler/Disassembler and Tools:
iASL: Implement limited typechecking for values returned from predefined
control methods. The type of any returned static (unnamed) object is now
validated. For example, Return(1). ACPICA BZ 786.
iASL: Fixed a predefined name object verification regression. Fixes a problem
introduced in version 20100304. An error is incorrectly generated if a
predefined name is declared as a static named object with a value defined
using the keywords "Zero", "One", or "Ones". Lin Ming.
iASL: Added Windows 7 support for the -g option (get local ACPI tables) by
reducing the requested registry access rights. ACPICA BZ 842.
Disassembler: fixed a possible fault when generating External() statements.
Introduced in commit ae7d6fd: Properly handle externals with parent-prefix
(carat). Fixes a string length allocation calculation. Lin Ming.
----------------------------------------
04 March 2010. Summary of changes for version 20100304:
1) ACPI CA Core Subsystem:
Fixed a possible problem with the AML Mutex handling function
AcpiExReleaseMutex where the function could fault under the very rare
condition when the interpreter has blocked, the interpreter lock is released,
the interpreter is then reentered via the same thread, and attempts to
acquire an AML mutex that was previously acquired. FreeBSD report 140979. Lin
Ming.
Implemented additional configuration support for the AML "Debug Object".
Output from the debug object can now be enabled via a global variable,
AcpiGbl_EnableAmlDebugObject. This will assist with remote machine debugging.
This debug output is now available in the release version of ACPICA instead
of just the debug version. Also, the entire debug output module can now be
configured out of the ACPICA build if desired. One new file added,
executer/exdebug.c. Lin Ming, Bob Moore.
Added header support for the ACPI MCHI table (Management Controller Host
Interface Table). This table was added in ACPI 4.0, but the defining document
has only recently become available.
Standardized output of integer values for ACPICA warnings/errors. Always use
0x prefix for hex output, always use %u for unsigned integer decimal output.
Affects ACPI_INFO, ACPI_ERROR, ACPI_EXCEPTION, and ACPI_WARNING (about 400
invocations.) These invocations were converted from the original
ACPI_DEBUG_PRINT invocations and were not consistent. ACPICA BZ 835.
Example Code and Data Size: These are the sizes for the OS-independent
acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The
debug version of the code includes the debug output trace mechanism and has a
much larger code and data size.

2) iASL Compiler/Disassembler and Tools:
iASL: Implemented typechecking support for static (non-control method)
predefined named objects that are declared with the Name() operator. For
example, the type of this object is now validated to be of type Integer:
Name(_BBN, 1). This change migrates the compiler to using the core predefined
name table instead of maintaining a local version. Added a new file,
aslpredef.c. ACPICA BZ 832.
Disassembler: Added support for the ACPI 4.0 MCHI table.
----------------------------------------
21 January 2010. Summary of changes for version 20100121:
1) ACPI CA Core Subsystem:
Added the 2010 copyright to all module headers and signons. This affects
virtually every file in the ACPICA core subsystem, the iASL compiler, the
tools/utilities, and the test suites.
Implemented a change to the AcpiGetDevices interface to eliminate unnecessary
invocations of the _STA method. In the case where a specific _HID is
requested, do not run _STA until a _HID match is found. This eliminates
potentially dozens of _STA calls during a search for a particular device/HID,
which in turn can improve boot times. ACPICA BZ 828. Lin Ming.
Implemented an additional repair for predefined method return values. Attempt
to repair unexpected NULL elements within returned Package objects. Create an
Integer of value zero, a NULL String, or a zero-length Buffer as appropriate.
ACPICA BZ 818. Lin Ming, Bob Moore.
Removed the obsolete ACPI_INTEGER data type. This type was introduced as the
code was migrated from ACPI 1.0 (with 32-bit AML integers) to ACPI 2.0 (with
64-bit AML integers). It is now obsolete and this change removes it from the
ACPICA code base, replaced by UINT64. The original typedef has been retained
for now for compatibility with existing device driver code. ACPICA BZ 824.
Removed the unused UINT32_STRUCT type, and the obsolete Integer64 field in
the parse tree object.
Added additional warning options for the gcc-4 generation. Updated the source
accordingly. This includes some code restructuring to eliminate unreachable
code, elimination of some gotos, elimination of unused return values, some
additional casting, and removal of redundant declarations.
Example Code and Data Size: These are the sizes for the OS-independent
acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The
debug version of the code includes the debug output trace mechanism and has a
much larger code and data size.

No functional changes for this release.
----------------------------------------
14 December 2009. Summary of changes for version 20091214:
1) ACPI CA Core Subsystem:
Enhanced automatic data type conversions for predefined name repairs. This
change expands the automatic repairs/conversions for predefined name return
values to make Integers, Strings, and Buffers fully interchangeable. Also, a
Buffer can be converted to a Package of Integers if necessary. The nsrepair.c
module was completely restructured. Lin Ming, Bob Moore.
Implemented automatic removal of null package elements during predefined name
repairs. This change will automatically remove embedded and trailing NULL
package elements from returned package objects that are defined to contain a
variable number of sub-packages. The driver is then presented with a package
with no null elements to deal with. ACPICA BZ 819.
Implemented a repair for the predefined _FDE and _GTM names. The expected
return value for both names is a Buffer of 5 DWORDs. This repair fixes two
possible problems (both seen in the field), where a package of integers is
returned, or a buffer of BYTEs is returned. With assistance from Jung-uk Kim.
Implemented additional module-level code support. This change will properly
execute module-level code that is not at the root of the namespace (under a
Device object, etc.). Now executes the code within the current scope instead
of the root. ACPICA BZ 762. Lin Ming.
Fixed possible mutex acquisition errors when running _REG methods. Fixes a
problem where mutex errors can occur when running a _REG method that is in
the same scope as a method-defined operation region or an operation region
under a module-level IF block. This type of code is rare, so the problem has
not been seen before. ACPICA BZ 826. Lin Ming, Bob Moore.
Fixed a possible memory leak during module-level code execution. An object
could be leaked for each block of executed module-level code if the
interpreter slack mode is enabled This change deletes any implicitly returned
object from the module-level code block. Lin Ming.
Removed messages for successful predefined repair(s). The repair mechanism
was considered too wordy. Now, messages are only unconditionally emitted if
the return object cannot be repaired. Existing messages for successful
repairs were converted to ACPI_DEBUG_PRINT messages for now. ACPICA BZ 827.
Example Code and Data Size: These are the sizes for the OS-independent
acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The
debug version of the code includes the debug output trace mechanism and has a
much larger code and data size.

Non-Debug Version: 87.0K Code, 18.0K Data, 105.0K Total
Debug Version: 163.4K Code, 50.8K Data, 214.2K Total
2) iASL Compiler/Disassembler and Tools:
iASL: Fixed a regression introduced in 20091112 where intermediate .SRC files
were no longer automatically removed at the termination of the compile.
acpiexec: Implemented the -f option to specify default region fill value.
This option specifies the value used to initialize buffers that simulate
operation regions. Default value is zero. Useful for debugging problems that
depend on a specific initial value for a region or field.
----------------------------------------
12 November 2009. Summary of changes for version 20091112:
1) ACPI CA Core Subsystem:
Implemented a post-order callback to AcpiWalkNamespace. The existing
interface only has a pre-order callback. This change adds an additional
parameter for a post-order callback which will be more useful for bus scans.
ACPICA BZ 779. Lin Ming. Updated the ACPICA Programmer Reference.
Modified the behavior of the operation region memory mapping cache for
SystemMemory. Ensure that the memory mappings created for operation regions
do not cross 4K page boundaries. Crossing a page boundary while mapping
regions can cause kernel warnings on some hosts if the pages have different
attributes. Such regions are probably BIOS bugs, and this is the workaround.
Linux BZ 14445. Lin Ming.
Implemented an automatic repair for predefined methods that must return
sorted lists. This change will repair (by sorting) packages returned by _ALR,
_PSS, and _TSS. Drivers can now assume that the packages are correctly sorted
and do not contain NULL package elements. Adds one new file,
namespace/nsrepair2.c. ACPICA BZ 784. Lin Ming, Bob Moore.
Fixed a possible fault during predefined name validation if a return Package
object contains NULL elements. Also adds a warning if a NULL element is
followed by any non-null elements. ACPICA BZ 813, 814. Future enhancement may
include repair or removal of all such NULL elements where possible.
Implemented additional module-level executable AML code support. This change
will execute module-level code that is not at the root of the namespace
(under a Device object, etc.) at table load time. Module-level executable AML
code has been illegal since ACPI 2.0. ACPICA BZ 762. Lin Ming.
Implemented a new internal function to create Integer objects. This function
simplifies miscellaneous object creation code. ACPICA BZ 823.
Reduced the severity of predefined repair messages, Warning to Info. Since
the object was successfully repaired, a warning is too severe. Reduced to an
info message for now. These messages may eventually be changed to debug-only.
ACPICA BZ 812.
Example Code and Data Size: These are the sizes for the OS-independent
acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The
debug version of the code includes the debug output trace mechanism and has a
much larger code and data size.

Debug Version: 161.8K Code, 50.6K Data, 212.4K Total

Non-Debug Version: 86.6K Code, 18.2K Data, 104.8K Total
Debug Version: 162.7K Code, 50.8K Data, 213.5K Total
2) iASL Compiler/Disassembler and Tools:
iASL: Implemented Switch() with While(1) so that Break works correctly. This
change correctly implements the Switch operator with a surrounding While(1)
so that the Break operator works as expected. ACPICA BZ 461. Lin Ming.
iASL: Added a message if a package initializer list is shorter than package
length. Adds a new remark for a Package() declaration if an initializer list
exists, but is shorter than the declared length of the package. Although
technically legal, this is probably a coding error and it is seen in the
field. ACPICA BZ 815. Lin Ming, Bob Moore.
iASL: Fixed a problem where the compiler could fault after the maximum number
of errors was reached (200).
acpixtract: Fixed a possible warning for pointer cast if the compiler warning
level set very high.
----------------------------------------
13 October 2009. Summary of changes for version 20091013:
1) ACPI CA Core Subsystem:
Fixed a problem where an Operation Region _REG method could be executed more
than once. If a custom address space handler is installed by the host before
the "initialize operation regions" phase of the ACPICA initialization, any
_REG methods for that address space could be executed twice. This change
fixes the problem. ACPICA BZ 427. Lin Ming.
Fixed a possible memory leak for the Scope() ASL operator. When the exact
invocation of "Scope(\)" is executed (change scope to root), one internal
operand object was leaked. Lin Ming.
Implemented a run-time repair for the _MAT predefined method. If the _MAT
return value is defined as a Field object in the AML, and the field
size is less than or equal to the default width of an integer (32 or 64),_MAT
can incorrectly return an Integer instead of a Buffer. ACPICA now
automatically repairs this problem. ACPICA BZ 810.
Implemented a run-time repair for the _BIF and _BIX predefined methods. The
"OEM Information" field is often incorrectly returned as an Integer with
value zero if the field is not supported by the platform. This is due to an
ambiguity in the ACPI specification. The field should always be a string.
ACPICA now automatically repairs this problem by returning a NULL string
within the returned Package. ACPICA BZ 807.
Example Code and Data Size: These are the sizes for the OS-independent
acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The
debug version of the code includes the debug output trace mechanism and has a
much larger code and data size.

2) iASL Compiler/Disassembler and Tools:
Disassembler: Fixed a problem where references to external symbols that
contained one or more parent-prefixes (carats) were not handled correctly,
possibly causing a fault. ACPICA BZ 806. Lin Ming.
Disassembler: Restructured the code so that all functions that handle
external symbols are in a single module. One new file is added,
common/dmextern.c.
AML Debugger: Added a max count argument for the Batch command (which
executes multiple predefined methods within the namespace.)
iASL: Updated the compiler documentation (User Reference.) Available at
http://www.acpica.org/documentation/. ACPICA BZ 750.
AcpiXtract: Updated for Lint and other formatting changes. Close all open
files.
----------------------------------------
03 September 2009. Summary of changes for version 20090903:
1) ACPI CA Core Subsystem:
For Windows Vista compatibility, added the automatic execution of an _INI
method located at the namespace root (\_INI). This method is executed at
table load time. This support is in addition to the automatic execution of
\_SB._INI. Lin Ming.
Fixed a possible memory leak in the interpreter for AML package objects if
the package initializer list is longer than the defined size of the package.
This apparently can only happen if the BIOS changes the package size on the
fly (seen in a _PSS object), as ASL compilers do not allow this. The
interpreter will truncate the package to the defined size (and issue an error
message), but previously could leave the extra objects undeleted if they were
pre-created during the argument processing (such is the case if the package
consists of a number of sub-packages as in the _PSS.) ACPICA BZ 805.
Fixed a problem seen when a Buffer or String is stored to itself via ASL.
This has been reported in the field. Previously, ACPICA would zero out the
buffer/string. Now, the operation is treated as a noop. Provides Windows
compatibility. ACPICA BZ 803. Lin Ming.
Removed an extraneous error message for ASL constructs of the form
Store(LocalX,LocalX) when LocalX is uninitialized. These curious statements
are seen in many BIOSs and are once again treated as NOOPs and no error is
emitted when they are encountered. ACPICA BZ 785.
Fixed an extraneous warning message if a _DSM reserved method returns a
Package object. _DSM can return any type of object, so validation on the
return type cannot be performed. ACPICA BZ 802.
Example Code and Data Size: These are the sizes for the OS-independent
acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The
debug version of the code includes the debug output trace mechanism and has a
much larger code and data size.

Non-Debug Version: 85.6K Code, 18.0K Data, 103.6K Total
Debug Version: 161.7K Code, 50.9K Data, 212.6K Total
2) iASL Compiler/Disassembler and Tools:
iASL: Fixed a problem with the use of the Alias operator and Resource
Templates. The correct alias is now constructed and no error is emitted.
ACPICA BZ 738.
iASL: Implemented the -I option to specify additional search directories for
include files. Allows multiple additional search paths for include files.
Directories are searched in the order specified on the command line (after
the local directory is searched.) ACPICA BZ 800.
iASL: Fixed a problem where the full pathname for include files was not
emitted for warnings/errors. This caused the IDE support to not work
properly. ACPICA BZ 765.
iASL: Implemented the -@ option to specify a Windows-style response file
containing additional command line options. ACPICA BZ 801.
AcpiExec: Added support to load multiple AML files simultaneously (such as a
DSDT and multiple SSDTs). Also added support for wildcards within the AML
pathname. These features allow all machine tables to be easily loaded and
debugged together. ACPICA BZ 804.
Disassembler: Added missing support for disassembly of HEST table Error Bank
subtables.
----------------------------------------
30 July 2009. Summary of changes for version 20090730:
The ACPI 4.0 implementation for ACPICA is complete with this release.
1) ACPI CA Core Subsystem:
ACPI 4.0: Added header file support for all new and changed ACPI tables.
Completely new tables are: IBFT, IVRS, MSCT, and WAET. Tables that are new
for ACPI 4.0, but have previously been supported in ACPICA are: CPEP, BERT,
EINJ, ERST, and HEST. Other newly supported tables are: UEFI and WDAT. There
have been some ACPI 4.0 changes to other existing tables. Split the large
actbl1.h header into the existing actbl2.h header. ACPICA BZ 774.
ACPI 4.0: Implemented predefined name validation for all new names. There are
31 new names in ACPI 4.0. The predefined validation module was split into two
files. The new file is namespace/nsrepair.c. ACPICA BZ 770.
Implemented support for so-called "module-level executable code". This is
executable AML code that exists outside of any control method and is intended
to be executed at table load time. Although illegal since ACPI 2.0, this type
of code still exists and is apparently still being created. Blocks of this
code are now detected and executed as intended. Currently, the code blocks
must exist under either an If, Else, or While construct; these are the
typical cases seen in the field. ACPICA BZ 762. Lin Ming.
Implemented an automatic dynamic repair for predefined names that return
nested Package objects. This applies to predefined names that are defined to
return a variable-length Package of sub-packages. If the number of sub-
packages is one, BIOS code is occasionally seen that creates a simple single
package with no sub-packages. This code attempts to fix the problem by
wrapping a new package object around the existing package. These methods can
be repaired: _ALR, _CSD, _HPX, _MLS, _PRT, _PSS, _TRT, and _TSS. ACPICA BZ
790.
Fixed a regression introduced in 20090625 for the AcpiGetDevices interface.
The _HID/_CID matching was broken and no longer matched IDs correctly. ACPICA
BZ 793.
Fixed a problem with AcpiReset where the reset would silently fail if the
register was one of the protected I/O ports. AcpiReset now bypasses the port
validation mechanism. This may eventually be driven into the AcpiRead/Write
interfaces.
Fixed a regression related to the recent update of the AcpiRead/Write
interfaces. A sleep/suspend could fail if the optional PM2 Control register
does not exist during an attempt to write the Bus Master Arbitration bit.
(However, some hosts already delete the code that writes this bit, and the
code may in fact be obsolete at this date.) ACPICA BZ 799.
Fixed a problem where AcpiTerminate could fault if inadvertently called twice
in succession. ACPICA BZ 795.
Example Code and Data Size: These are the sizes for the OS-independent
acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The
debug version of the code includes the debug output trace mechanism and has a
much larger code and data size.

2) iASL Compiler/Disassembler and Tools:
ACPI 4.0: Implemented disassembler support for all new ACPI tables and
changes to existing tables. ACPICA BZ 775.
----------------------------------------
25 June 2009. Summary of changes for version 20090625:
The ACPI 4.0 Specification was released on June 16 and is available at
www.acpi.info. ACPICA implementation of ACPI 4.0 is underway and will
continue for the next few releases.
1) ACPI CA Core Subsystem:
ACPI 4.0: Implemented interpreter support for the IPMI operation region
address space. Includes support for bi-directional data buffers and an IPMI
address space handler (to be installed by an IPMI device driver.) ACPICA BZ
773. Lin Ming.
ACPI 4.0: Added changes for existing ACPI tables - FACS and SRAT. Includes
support in both the header files and the disassembler.
Completed a major update for the AcpiGetObjectInfo external interface.
Changes include:
- Support for variable, unlimited length HID, UID, and CID strings.
- Support Processor objects the same as Devices (HID,UID,CID,ADR,STA, etc.)
- Call the _SxW power methods on behalf of a device object.
- Determine if a device is a PCI root bridge.
- Change the ACPI_BUFFER parameter to ACPI_DEVICE_INFO.
These changes will require an update to all callers of this interface. See
the updated ACPICA Programmer Reference for details. One new source file has
been added - utilities/utids.c. ACPICA BZ 368, 780.
Updated the AcpiRead and AcpiWrite external interfaces to support 64-bit
transfers. The Value parameter has been extended from 32 bits to 64 bits in
order to support new ACPI 4.0 tables. These changes will require an update to
all callers of these interfaces. See the ACPICA Programmer Reference for
details. ACPICA BZ 768.
Fixed several problems with AcpiAttachData. The handler was not invoked when
the host node was deleted. The data sub-object was not automatically deleted
when the host node was deleted. The interface to the handler had an unused
parameter, this was removed. ACPICA BZ 778.
Enhanced the function that dumps ACPI table headers. All non-printable
characters in the string fields are now replaced with '?' (Signature, OemId,
OemTableId, and CompilerId.) ACPI tables with non-printable characters in
these fields are occasionally seen in the field. ACPICA BZ 788.
Fixed a problem with predefined method repair code where the code that
attempts to repair/convert an object of incorrect type is only executed on
the first time the predefined method is called. The mechanism that disables
warnings on subsequent calls was interfering with the repair mechanism.
ACPICA BZ 781.
Fixed a possible memory leak in the predefined validation/repair code when a
buffer is automatically converted to an expected string object.
Removed obsolete 16-bit files from the distribution and from the current git
tree head. ACPICA BZ 776.
Example Code and Data Size: These are the sizes for the OS-independent
acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The
debug version of the code includes the debug output trace mechanism and has a
much larger code and data size.

ACPI 4.0: iASL and Disassembler - implemented support for the new IPMI
operation region keyword. ACPICA BZ 771, 772. Lin Ming.
ACPI 4.0: iASL - implemented compile-time validation support for all new
predefined names and control methods (31 total). ACPICA BZ 769.
----------------------------------------
21 May 2009. Summary of changes for version 20090521:
1) ACPI CA Core Subsystem:
Disabled the preservation of the SCI enable bit in the PM1 control register.
The SCI enable bit (bit 0, SCI_EN) is defined by the ACPI specification to be
a "preserved" bit - "OSPM always preserves this bit position", section
4.7.3.2.1. However, some machines fail if this bit is in fact preserved
because the bit needs to be explicitly set by the OS as a workaround. No
machines fail if the bit is not preserved. Therefore, ACPICA no longer
attempts to preserve this bit.
Fixed a problem in AcpiRsGetPciRoutingTableLength where an invalid or
incorrectly formed _PRT package could cause a fault. Added validation to
ensure that each package element is actually a sub-package.
Implemented a new interface to install or override a single control method,
AcpiInstallMethod. This interface is useful when debugging in order to repair
an existing method or to install a missing method without having to override
the entire ACPI table. See the ACPICA Programmer Reference for use and
examples. Lin Ming, Bob Moore.
Fixed several reference count issues with the DdbHandle object that is
created from a Load or LoadTable operator. Prevent premature deletion of the
object. Also, mark the object as invalid once the table has been unloaded.
This is needed because the handle itself may not be deleted after the table
unload, depending on whether it has been stored in a named object by the
caller. Lin Ming.
Fixed a problem with Mutex Sync Levels. Fixed a problem where if multiple
mutexes of the same sync level are acquired but then not released in strict
opposite order, the internally maintained Current Sync Level becomes confused
and can cause subsequent execution errors. ACPICA BZ 471.
Changed the allowable release order for ASL mutex objects. The ACPI 4.0
specification has been changed to make the SyncLevel for mutex objects more
useful. When releasing a mutex, the SyncLevel of the mutex must now be the
same as the current sync level. This makes more sense than the previous rule
(SyncLevel less than or equal). This change updates the code to match the
specification.
Fixed a problem with the local version of the AcpiOsPurgeCache function. The
(local) cache must be locked during all cache object deletions. Andrew
Baumann.
Updated the Load operator to use operation region interfaces. This replaces
direct memory mapping with region access calls. Now, all region accesses go
through the installed region handler as they should.
Simplified and optimized the NsGetNextNode function. Reduced parameter count
and reduced code for this frequently used function.
Example Code and Data Size: These are the sizes for the OS-independent
acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The
debug version of the code includes the debug output trace mechanism and has a
much larger code and data size.

with sub-table disassembly and handling invalid sub-tables. Attempt recovery
after an invalid sub-table ID.

22 April 2009. Summary of changes for version 20090422:
1) ACPI CA Core Subsystem:
Fixed a compatibility issue with the recently released I/O port protection
mechanism. For windows compatibility, 1) On a port protection violation,
simply ignore the request and do not return an exception (allow the control
method to continue execution.) 2) If only part of the request overlaps a
protected port, read/write the individual ports that are not protected. Linux
BZ 13036. Lin Ming
Enhanced the execution of the ASL/AML BreakPoint operator so that it actually
breaks into the AML debugger if the debugger is present. This matches the
ACPI-defined behavior.
Fixed several possible warnings related to the use of the configurable
ACPI_THREAD_ID. This type can now be configured as either an integer or a
pointer with no warnings. Also fixes several warnings in printf-like
statements for the 64-bit build when the type is configured as a pointer.
ACPICA BZ 766, 767.
Fixed a number of possible warnings when compiling with gcc 4+ (depending on
warning options.) Examples include printf formats, aliasing, unused globals,
missing prototypes, missing switch default statements, use of non-ANSI
library functions, use of non-ANSI constructs. See generate/unix/Makefile for
a list of warning options used with gcc 3 and 4. ACPICA BZ 735.
Example Code and Data Size: These are the sizes for the OS-independent
acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The
debug version of the code includes the debug output trace mechanism and has a
much larger code and data size.
Previous Release:
Non-Debug Version: 82.6K Code, 17.6K Data, 100.2K Total
Debug Version: 157.7K Code, 49.9K Data, 207.6K Total
Current Release:
Non-Debug Version: 82.8K Code, 17.5K Data, 100.3K Total
Debug Version: 158.0K Code, 49.9K Data, 207.9K Total
2) iASL Compiler/Disassembler and Tools:
iASL: Fixed a generation warning from Bison 2.3 and fixed several warnings on
the 64-bit build.
iASL: Fixed a problem where the Unix/Linux versions of the compiler could not
correctly digest Windows/DOS formatted files (with CR/LF).
iASL: Added a new option for "quiet mode" (-va) that produces only the
compilation summary, not individual errors and warnings. Useful for large
batch compilations.
AcpiExec: Implemented a new option (-z) to enable a forced semaphore/mutex
timeout that can be used to detect hang conditions during execution of AML
code (includes both internal semaphores and AML-defined mutexes and events.)
Added new makefiles for the generation of acpica in a generic unix-like
environment. These makefiles are intended to generate the acpica tools and
utilities from the original acpica git source tree structure.
Test Suites: Updated and cleaned up the documentation files. Updated the
copyrights to 2009, affecting all source files. Use the new version of iASL
with quiet mode. Increased the number of available semaphores in the Windows
OSL, allowing the aslts to execute fully on Windows. For the Unix OSL, added
an alternate implementation of the semaphore timeout to allow aslts to
execute fully on Cygwin.
----------------------------------------
20 March 2009. Summary of changes for version 20090320:
1) ACPI CA Core Subsystem:
Fixed a possible race condition between AcpiWalkNamespace and dynamic table
unloads. Added a reader/writer locking mechanism to allow multiple concurrent
namespace walks (readers), but block a dynamic table unload until it can gain
exclusive write access to the namespace. This fixes a problem where a table
unload could (possibly catastrophically) delete the portion of the namespace
that is currently being examined by a walk. Adds a new file, utlock.c, that
implements the reader/writer lock mechanism. ACPICA BZ 749.
Fixed a regression introduced in version 20090220 where a change to the FADT
handling could cause the ACPICA subsystem to access non-existent I/O ports.
Modified the handling of FADT register and table (FACS/DSDT) addresses. The
FADT can contain both 32-bit and 64-bit versions of these addresses.
Previously, the 64-bit versions were favored, meaning that if both 32 and 64
versions were valid, but not equal, the 64-bit version was used. This was
found to cause some machines to fail. Now, in this case, the 32-bit version
is used instead. This now matches the Windows behavior.
Implemented a new mechanism to protect certain I/O ports. Provides Microsoft
compatibility and protects the standard PC I/O ports from access via AML
code. Adds a new file, hwvalid.c
Fixed a possible extraneous warning message from the FADT support. The
message warns of a 32/64 length mismatch between the legacy and GAS
definitions for a register.
Removed the obsolete AcpiOsValidateAddress OSL interface. This interface is
made obsolete by the port protection mechanism above. It was previously used
to validate the entire address range of an operation region, which could be
incorrect if the range included illegal ports, but fields within the
operation region did not actually access those ports. Validation is now
performed on a per-field basis instead of the entire region.
Modified the handling of the PM1 Status Register ignored bit (bit 11.)
Ignored bits must be "preserved" according to the ACPI spec. Usually, this
means a read/modify/write when writing to the register. However, for status
registers, writing a one means clear the event. Writing a zero means preserve
the event (do not clear.) This behavior is clarified in the ACPI 4.0 spec,
and the ACPICA code now simply always writes a zero to the ignored bit.
Modified the handling of ignored bits for the PM1 A/B Control Registers. As
per the ACPI specification, for the control registers, preserve
(read/modify/write) all bits that are defined as either reserved or ignored.
Updated the handling of write-only bits in the PM1 A/B Control Registers.
When reading the register, zero the write-only bits as per the ACPI spec.
ACPICA BZ 443. Lin Ming.
Removed "Linux" from the list of supported _OSI strings. Linux no longer
wants to reply true to this request. The Windows strings are the only paths
through the AML that are tested and known to work properly.

2) iASL Compiler/Disassembler and Tools:
Acpiexec: Split the large aeexec.c file into two new files, aehandlers.c and
aetables.c
----------------------------------------
20 February 2009. Summary of changes for version 20090220:
1) ACPI CA Core Subsystem:
Optimized the ACPI register locking. Removed locking for reads from the ACPI
bit registers in PM1 Status, Enable, Control, and PM2 Control. The lock is
not required when reading the single-bit registers. The
AcpiGetRegisterUnlocked function is no longer needed and has been removed.
This will improve performance for reads on these registers. ACPICA BZ 760.
Fixed the parameter validation for AcpiRead/Write. Now return
AE_BAD_PARAMETER if the input register pointer is null, and AE_BAD_ADDRESS if
the register has an address of zero. Previously, these cases simply returned
AE_OK. For optional registers such as PM1B status/enable/control, the caller
should check for a valid register address before calling. ACPICA BZ 748.
Renamed the external ACPI bit register access functions. Renamed
AcpiGetRegister and AcpiSetRegister to clarify the purpose of these
functions. The new names are AcpiReadBitRegister and AcpiWriteBitRegister.
Also, restructured the code for these functions by simplifying the code path
and condensing duplicate code to reduce code size.
Added new functions to transparently handle the possibly split PM1 A/B
registers. AcpiHwReadMultiple and AcpiHwWriteMultiple. These two functions
now handle the split registers for PM1 Status, Enable, and Control. ACPICA BZ
746.
Added a function to handle the PM1 control registers, AcpiHwWritePm1Control.
This function writes both of the PM1 control registers (A/B). These registers
are different than the PM1 A/B status and enable registers in that different
values can be written to the A/B registers. Most notably, the SLP_TYP bits
can be different, as per the values returned from the _Sx predefined methods.
Removed an extra register write within AcpiHwClearAcpiStatus. This function
was writing an optional PM1B status register twice. The existing call to the
low-level AcpiHwRegisterWrite automatically handles a possibly split PM1 A/B
register. ACPICA BZ 751.
Split out the PM1 Status registers from the FADT. Added new globals for these
registers (A/B), similar to the way the PM1 Enable registers are handled.
Instead of overloading the FADT Event Register blocks. This makes the code
clearer and less prone to error.
Fixed the warning message for when the platform contains too many ACPI tables
for the default size of the global root table data structure. The calculation
for the truncation value was incorrect.
Removed the ACPI_GET_OBJECT_TYPE macro. Removed all instances of this
obsolete macro, since it is now a simple reference to ->common.type. There
were about 150 invocations of the macro across 41 files. ACPICA BZ 755.
Removed the redundant ACPI_BITREG_SLEEP_TYPE_B. This type is the same as
TYPE_A. Removed this and all related instances. Renamed SLEEP_TYPE_A to
simply SLEEP_TYPE. ACPICA BZ 754.
Conditionally compile the AcpiSetFirmwareWakingVector64 function. This
function is only needed on 64-bit host operating systems and is thus not
included for 32-bit hosts.
Debug output: print the input and result for invocations of the _OSI reserved
control method via the ACPI_LV_INFO debug level. Also, reduced some of the
verbosity of this debug level. Len Brown.
Example Code and Data Size: These are the sizes for the OS-independent
acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The
debug version of the code includes the debug output trace mechanism and has a
much larger code and data size.

2) iASL Compiler/Disassembler and Tools:
Disassembler: Decode the FADT PM_Profile field. Emit ascii names for the
various legal performance profiles.
----------------------------------------
23 January 2009. Summary of changes for version 20090123:
1) ACPI CA Core Subsystem:
Added the 2009 copyright to all module headers and signons. This affects
virtually every file in the ACPICA core subsystem, the iASL compiler, and
the tools/utilities.
Implemented a change to allow the host to override any ACPI table, including
dynamically loaded tables. Previously, only the DSDT could be replaced by the
host. With this change, the AcpiOsTableOverride interface is called for each
table found in the RSDT/XSDT during ACPICA initialization, and also whenever
a table is dynamically loaded via the AML Load operator.
Updated FADT flag definitions, especially the Boot Architecture flags.
Debugger: For the Find command, automatically pad the input ACPI name with
underscores if the name is shorter than 4 characters. This enables a match
with the actual namespace entry which is itself padded with underscores.
Example Code and Data Size: These are the sizes for the OS-independent
acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The
debug version of the code includes the debug output trace mechanism and has a
much larger code and data size.

Non-Debug Version: 82.3K Code, 17.5K Data, 99.8K Total
Debug Version: 157.3K Code, 49.8K Data, 207.1K Total
2) iASL Compiler/Disassembler and Tools:
Fix build error under Bison-2.4.
Dissasembler: Enhanced FADT support. Added decoding of the Boot Architecture
flags. Now decode all flags, regardless of the FADT version. Flag output
includes the FADT version which first defined each flag.
The iASL -g option now dumps the RSDT to a file (in addition to the FADT and
DSDT). Windows only.
----------------------------------------
04 December 2008. Summary of changes for version 20081204:
1) ACPI CA Core Subsystem:
The ACPICA Programmer Reference has been completely updated and revamped for
this release. This includes updates to the external interfaces, OSL
interfaces, the overview sections, and the debugger reference.
Several new ACPICA interfaces have been implemented and documented in the
programmer reference:
AcpiReset - Writes the reset value to the FADT-defined reset register.
AcpiDisableAllGpes - Disable all available GPEs.
AcpiEnableAllRuntimeGpes - Enable all available runtime GPEs.
AcpiGetGpeDevice - Get the GPE block device associated with a GPE.
AcpiGbl_CurrentGpeCount - Tracks the current number of available GPEs.
AcpiRead - Low-level read ACPI register (was HwLowLevelRead.)
AcpiWrite - Low-level write ACPI register (was HwLowLevelWrite.)
Most of the public ACPI hardware-related interfaces have been moved to a new
file, components/hardware/hwxface.c
Enhanced the FADT parsing and low-level ACPI register access: The ACPI
register lengths within the FADT are now used, and the low level ACPI
register access no longer hardcodes the ACPI register lengths. Given that
there may be some risk in actually trusting the FADT register lengths, a run-
time option was added to fall back to the default hardcoded lengths if the
FADT proves to contain incorrect values - UseDefaultRegisterWidths. This
option is set to true for now, and a warning is issued if a suspicious FADT
register length is overridden with the default value.
Fixed a reference count issue in NsRepairObject. This problem was introduced
in version 20081031 as part of a fix to repair Buffer objects within
Packages. Lin Ming.
Added semaphore support to the Linux/Unix application OS-services layer
(OSL). ACPICA BZ 448. Lin Ming.
Added the ACPI_MUTEX_TYPE configuration option to select whether mutexes will
be implemented in the OSL, or will binary semaphores be used instead.
Example Code and Data Size: These are the sizes for the OS-independent
acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The
debug version of the code includes the debug output trace mechanism and has a
much larger code and data size.
Previous Release:
Non-Debug Version: 81.7K Code, 17.3K Data, 99.0K Total
Debug Version: 156.4K Code, 49.4K Data, 205.8K Total
Current Release:
Non-Debug Version: 82.3K Code, 17.4K Data, 99.7K Total
Debug Version: 157.1K Code, 49.7K Data, 206.8K Total
2) iASL Compiler/Disassembler and Tools:
iASL: Completed the '-e' option to include additional ACPI tables in order to
aid with disassembly and External statement generation. ACPICA BZ 742. Lin
Ming.
iASL: Removed the "named object in while loop" error. The compiler cannot
determine how many times a loop will execute. ACPICA BZ 730.
Disassembler: Implemented support for FADT revision 2 (MS extension). ACPICA
BZ 743.
Disassembler: Updates for several ACPI data tables (HEST, EINJ, and MCFG).
----------------------------------------
31 October 2008. Summary of changes for version 20081031:
1) ACPI CA Core Subsystem:
Restructured the ACPICA header files into public/private. acpi.h now includes
only the "public" acpica headers. All other acpica headers are "private" and
should not be included by acpica users. One new file, accommon.h is used to
include the commonly used private headers for acpica code generation. Future
plans include moving all private headers to a new subdirectory.
Implemented an automatic Buffer->String return value conversion for
predefined ACPI methods. For these methods (such as _BIF), added automatic
conversion for return objects that are required to be a String, but a Buffer
was found instead. This can happen when reading string battery data from an
operation region, because it used to be difficult to convert the data from
buffer to string from within the ASL. Ensures that the host OS is provided
with a valid null-terminated string. Linux BZ 11822.
Updated the FACS waking vector interfaces. Split AcpiSetFirmwareWakingVector
into two: one for the 32-bit vector, another for the 64-bit vector. This is
required because the host OS must setup the wake much differently for each
vector (real vs. protected mode, etc.) and the interface itself should not be
deciding which vector to use. Also, eliminated the GetFirmwareWakingVector
interface, as it served no purpose (only the firmware reads the vector, OS
only writes the vector.) ACPICA BZ 731.
Implemented a mechanism to escape infinite AML While() loops. Added a loop
counter to force exit from AML While loops if the count becomes too large.
This can occur in poorly written AML when the hardware does not respond
within a while loop and the loop does not implement a timeout. The maximum
loop count is configurable. A new exception code is returned when a loop is
broken, AE_AML_INFINITE_LOOP. Alexey Starikovskiy, Bob Moore.
Optimized the execution of AML While loops. Previously, a control state
object was allocated and freed for each execution of the loop. The
optimization is to simply reuse the control state for each iteration. This
speeds up the raw loop execution time by about 5%.
Enhanced the implicit return mechanism. For Windows compatibility, return an
implicit integer of value zero for methods that contain no executable code.
Such methods are seen in the field as stubs (presumably), and can cause
drivers to fail if they expect a return value. Lin Ming.
Allow multiple backslashes as root prefixes in namepaths. In a fully
qualified namepath, allow multiple backslash prefixes. This can happen (and
is seen in the field) because of the use of a double-backslash in strings
(since backslash is the escape character) causing confusion. ACPICA BZ 739
Lin Ming.
Emit a warning if two different FACS or DSDT tables are discovered in the
FADT. Checks if there are two valid but different addresses for the FACS and
DSDT within the FADT (mismatch between the 32-bit and 64-bit fields.)
Consolidated the method argument count validation code. Merged the code that
validates control method argument counts into the predefined validation
module. Eliminates possible multiple warnings for incorrect argument counts.
Implemented ACPICA example code. Includes code for ACPICA initialization,
handler installation, and calling a control method. Available at
source/tools/examples.
Added a global pointer for FACS table to simplify internal FACS access. Use
the global pointer instead of using AcpiGetTableByIndex for each FACS access.
This simplifies the code for the Global Lock and the Firmware Waking
Vector(s).
Example Code and Data Size: These are the sizes for the OS-independent
acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The
debug version of the code includes the debug output trace mechanism and has a
much larger code and data size.

Debug Version: 155.8K Code, 49.1K Data, 204.9K Total
Current Release:
Non-Debug Version: 81.7K Code, 17.3K Data, 99.0K Total
Debug Version: 156.4K Code, 49.4K Data, 205.8K Total
2) iASL Compiler/Disassembler and Tools:
iASL: Improved disassembly of external method calls. Added the -e option to
allow the inclusion of additional ACPI tables to help with the disassembly of
method invocations and the generation of external declarations during the
disassembly. Certain external method invocations cannot be disassembled
properly without the actual declaration of the method. Use the -e option to
include the table where the external method(s) are actually declared. Most
useful for disassembling SSDTs that make method calls back to the master
DSDT. Lin Ming. Example: To disassemble an SSDT with calls to DSDT: iasl -d
-e dsdt.aml ssdt1.aml
iASL: Fix to allow references to aliases within ASL namepaths. Fixes a
problem where the use of an alias within a namepath would result in a not
found error or cause the compiler to fault. Also now allows forward
references from the Alias operator itself. ACPICA BZ 738.
----------------------------------------
26 September 2008. Summary of changes for version 20080926:
1) ACPI CA Core Subsystem:
Designed and implemented a mechanism to validate predefined ACPI methods and
objects. This code validates the predefined ACPI objects (objects whose names
start with underscore) that appear in the namespace, at the time they are
evaluated. The argument count and the type of the returned object are
validated against the ACPI specification. The purpose of this validation is
to detect problems with the BIOS-implemented predefined ACPI objects before
the results are returned to the ACPI-related drivers. Future enhancements may
include actual repair of incorrect return objects where possible. Two new
files are nspredef.c and acpredef.h.
Fixed a fault in the AML parser if a memory allocation fails during the Op
completion routine AcpiPsCompleteThisOp. Lin Ming. ACPICA BZ 492.
Fixed an issue with implicit return compatibility. This change improves the
implicit return mechanism to be more compatible with the MS interpreter. Lin
Ming, ACPICA BZ 349.
Implemented support for zero-length buffer-to-string conversions. Allow zero
length strings during interpreter buffer-to-string conversions. For example,
during the ToDecimalString and ToHexString operators, as well as implicit
conversions. Fiodor Suietov, ACPICA BZ 585.
Fixed two possible memory leaks in the error exit paths of
AcpiUtUpdateObjectReference and AcpiUtWalkPackageTree. These functions are
similar in that they use a stack of state objects in order to eliminate
recursion. The stack must be fully unwound and deallocated if an error
occurs. Lin Ming. ACPICA BZ 383.
Removed the unused ACPI_BITREG_WAKE_ENABLE definition and entry in the global
ACPI register table. This bit does not exist and is unused. Lin Ming, Bob
Moore ACPICA BZ 442.
Removed the obsolete version number in module headers. Removed the
"$Revision" number that appeared in each module header. This version number
was useful under SourceSafe and CVS, but has no meaning under git. It is not
only incorrect, it could also be misleading.
Example Code and Data Size: These are the sizes for the OS-independent
acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The
debug version of the code includes the debug output trace mechanism and has a
much larger code and data size.

----------------------------------------
29 August 2008. Summary of changes for version 20080829:
1) ACPI CA Core Subsystem:
Completed a major cleanup of the internal ACPI_OPERAND_OBJECT of type
Reference. Changes include the elimination of cheating on the Object field
for the DdbHandle subtype, addition of a reference class field to
differentiate the various reference types (instead of an AML opcode), and the
cleanup of debug output for this object. Lin Ming, Bob Moore. BZ 723
Reduce an error to a warning for an incorrect method argument count.
Previously aborted with an error if too few arguments were passed to a
control method via the external ACPICA interface. Now issue a warning instead
and continue. Handles the case where the method inadvertently declares too
many arguments, but does not actually use the extra ones. Applies mainly to
the predefined methods. Lin Ming. Linux BZ 11032.
Disallow the evaluation of named object types with no intrinsic value. Return
AE_TYPE for objects that have no value and therefore evaluation is undefined:
Device, Event, Mutex, Region, Thermal, and Scope. Previously, evaluation of
these types were allowed, but an exception would be generated at some point
during the evaluation. Now, the error is generated up front.
Fixed a possible memory leak in the AcpiNsGetExternalPathname function
(nsnames.c). Fixes a leak in the error exit path.
Removed the obsolete debug levels ACPI_DB_WARN and ACPI_DB_ERROR. These debug
levels were made obsolete by the ACPI_WARNING, ACPI_ERROR, and ACPI_EXCEPTION
interfaces. Also added ACPI_DB_EVENTS to correspond with the existing
ACPI_LV_EVENTS.
Removed obsolete and/or unused exception codes from the acexcep.h header.
There is the possibility that certain device drivers may be affected if they
use any of these exceptions.
The ACPICA documentation has been added to the public git source tree, under
acpica/documents. Included are the ACPICA programmer reference, the iASL
compiler reference, and the changes.txt release logfile.
Example Code and Data Size: These are the sizes for the OS-independent
acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The
debug version of the code includes the debug output trace mechanism and has a
much larger code and data size.

Current Release:
Non-Debug Version: 79.7K Code, 16.4K Data, 96.1K Total
Debug Version: 153.7K Code, 48.2K Data, 201.9K Total
2) iASL Compiler/Disassembler and Tools:
Allow multiple argument counts for the predefined _SCP method. ACPI 3.0
defines _SCP with 3 arguments. Previous versions defined it with only 1
argument. iASL now allows both definitions.
iASL/disassembler: avoid infinite loop on bad ACPI tables. Check for zero-
length subtables when disassembling ACPI tables. Also fixed a couple of
errors where a full 16-bit table type field was not extracted from the input
properly.
acpisrc: Improve comment counting mechanism for generating source code
statistics. Count first and last lines of multi-line comments as whitespace,
not comment lines. Handle Linux legal header in addition to standard acpica
header.
----------------------------------------
29 July 2008. Summary of changes for version 20080729:
1) ACPI CA Core Subsystem:
Fix a possible deadlock in the GPE dispatch. Remove call to
AcpiHwDisableAllGpes during wake in AcpiEvGpeDispatch. This call will attempt
to acquire the GPE lock but can deadlock since the GPE lock is already held
at dispatch time. This code was introduced in version 20060831 as a response
to Linux BZ 6881 and has since been removed from Linux.
Add a function to dereference returned reference objects. Examines the return
object from a call to AcpiEvaluateObject. Any Index or RefOf references are
automatically dereferenced in an attempt to return something useful (these
reference types cannot be converted into an external ACPI_OBJECT.) Provides
MS compatibility. Lin Ming, Bob Moore. Linux BZ 11105
x2APIC support: changes for MADT and SRAT ACPI tables. There are 2 new
subtables for the MADT and one new subtable for the SRAT. Includes
disassembler and AcpiSrc support. Data from the Intel 64 Architecture x2APIC
Specification, June 2008.
Additional error checking for pathname utilities. Add error check after all
calls to AcpiNsGetPathnameLength. Add status return from
AcpiNsBuildExternalPath and check after all calls. Add parameter validation
to AcpiUtInitializeBuffer. Reported by and initial patch by Ingo Molnar.
Return status from the global init function AcpiUtGlobalInitialize. This is
used by both the kernel subsystem and the utilities such as iASL compiler.
The function could possibly fail when the caches are initialized. Yang Yi.
Add a function to decode reference object types to strings. Created for
improved error messages.
Improve object conversion error messages. Better error messages during object
conversion from internal to the external ACPI_OBJECT. Used for external calls
to AcpiEvaluateObject.
Example Code and Data Size: These are the sizes for the OS-independent
acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The
debug version of the code includes the debug output trace mechanism and has a
much larger code and data size.

2) iASL Compiler/Disassembler and Tools:
Debugger: fix a possible hang when evaluating non-methods. Fixes a problem
introduced in version 20080701. If the object being evaluated (via execute
command) is not a method, the debugger can hang while trying to obtain non-
existent parameters.
iASL: relax error for using reserved "_T_x" identifiers. These names can
appear in a disassembled ASL file if they were emitted by the original
compiler. Instead of issuing an error or warning and forcing the user to
manually change these names, issue a remark instead.
iASL: error if named object created in while loop. Emit an error if any named
object is created within a While loop. If allowed, this code will generate a
run-time error on the second iteration of the loop when an attempt is made to
create the same named object twice. ACPICA bugzilla 730.
iASL: Support absolute pathnames for include files. Add support for absolute
pathnames within the Include operator. previously, only relative pathnames
were supported.
iASL: Enforce minimum 1 interrupt in interrupt macro and Resource Descriptor.
The ACPI spec requires one interrupt minimum. BZ 423
iASL: Handle a missing ResourceSource arg, with a present SourceIndex.
Handles the case for the Interrupt Resource Descriptor where
the ResourceSource argument is omitted but ResourceSourceIndex
is present. Now leave room for the Index. BZ 426
iASL: Prevent error message if CondRefOf target does not exist. Fixes cases
where an error message is emitted if the target does not exist. BZ 516
iASL: Fix broken -g option (get Windows ACPI tables). Fixes the -g option
(get ACPI tables on Windows). This was apparently broken in version 20070919.
AcpiXtract: Handle EOF while extracting data. Correctly handle the case where
the EOF happens immediately after the last table in the input file. Print
completion message. Previously, no message was displayed in this case.
----------------------------------------
01 July 2008. Summary of changes for version 20080701:
0) Git source tree / acpica.org
Fixed a problem where a git-clone from http would not transfer the entire
source tree.
1) ACPI CA Core Subsystem:
Implemented a "careful" GPE disable in AcpiEvDisableGpe, only modify one
enable bit. Now performs a read-change-write of the enable register instead
of simply writing out the cached enable mask. This will prevent inadvertent
enabling of GPEs if a rogue GPE is received during initialization (before GPE
handlers are installed.)
Implemented a copy for dynamically loaded tables. Previously, dynamically
loaded tables were simply mapped - but on some machines this memory is
corrupted after suspend. Now copy the table to a local buffer. For the
OpRegion case, added checksum verify. Use the table length from the table
header, not the region length. For the Buffer case, use the table length
also. Dennis Noordsij, Bob Moore. BZ 10734
Fixed a problem where the same ACPI table could not be dynamically loaded and
unloaded more than once. Without this change, a table cannot be loaded again
once it has been loaded/unloaded one time. The current mechanism does not
unregister a table upon an unload. During a load, if the same table is found,
this no longer returns an exception. BZ 722
Fixed a problem where the wrong descriptor length was calculated for the
EndTag descriptor in 64-bit mode. The "minimal" descriptors such as EndTag
are calculated as 12 bytes long, but the actual length in the internal
descriptor is 16 because of the round-up to 8 on the 64-bit build. Reported
by Linn Crosetto. BZ 728
Fixed a possible memory leak in the Unload operator. The DdbHandle returned
by Load() did not have its reference count decremented during unload, leading
to a memory leak. Lin Ming. BZ 727
Fixed a possible memory leak when deleting thermal/processor objects. Any
associated notify handlers (and objects) were not being deleted. Fiodor
Suietov. BZ 506
Fixed the ordering of the ASCII names in the global mutex table to match the
actual mutex IDs. Used by AcpiUtGetMutexName, a function used for debug only.
Vegard Nossum. BZ 726
Enhanced the AcpiGetObjectInfo interface to return the number of required
arguments if the object is a control method. Added this call to the debugger
so the proper number of default arguments are passed to a method. This
prevents a warning when executing methods from AcpiExec.
Added a check for an invalid handle in AcpiGetObjectInfo. Return
AE_BAD_PARAMETER if input handle is invalid. BZ 474
Fixed an extraneous warning from exconfig.c on the 64-bit build.
Example Code and Data Size: These are the sizes for the OS-independent
acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The
debug version of the code includes the debug output trace mechanism and has a
much larger code and data size.
Previous Release:
Non-Debug Version: 79.3K Code, 16.2K Data, 95.5K Total
Debug Version: 153.0K Code, 48.2K Data, 201.2K Total
Current Release:
Non-Debug Version: 79.6K Code, 16.2K Data, 95.8K Total
Debug Version: 153.5K Code, 48.2K Data, 201.7K Total
2) iASL Compiler/Disassembler and Tools:
iASL: Added two missing ACPI reserved names. Added _MTP and _ASZ, both
resource descriptor names.
iASL: Detect invalid ASCII characters in input (windows version). Removed the
"-CF" flag from the flex compile, enables correct detection of non-ASCII
characters in the input. BZ 441
iASL: Eliminate warning when result of LoadTable is not used. Eliminate the
"result of operation not used" warning when the DDB handle returned from
LoadTable is not used. The warning is not needed. BZ 590
AcpiExec: Add support for dynamic table load/unload. Now calls _CFG method to
pass address of table to the AML. Added option to disable OpRegion simulation
to allow creation of an OpRegion with a real address that was passed to _CFG.
All of this allows testing of the Load and Unload operators from AcpiExec.
Debugger: update tables command for unloaded tables. Handle unloaded tables
and use the standard table header output routine.
----------------------------------------
09 June 2008. Summary of changes for version 20080609:
1) ACPI CA Core Subsystem:
Implemented a workaround for reversed _PRT entries. A significant number of
BIOSs erroneously reverse the _PRT SourceName and the SourceIndex. This
change dynamically detects and repairs this problem. Provides compatibility
with MS ACPI. BZ 6859
Simplified the internal ACPI hardware interfaces to eliminate the locking
flag parameter from Register Read/Write. Added a new external interface,
AcpiGetRegisterUnlocked.
Fixed a problem where the invocation of a GPE control method could hang. This
was a regression introduced in 20080514. The new method argument count
validation mechanism can enter an infinite loop when a GPE method is
dispatched. Problem fixed by removing the obsolete code that passed GPE block
information to the notify handler via the control method parameter pointer.
Fixed a problem where the _SST execution status was incorrectly returned to
the caller of AcpiEnterSleepStatePrep. This was a regression introduced in
20080514. _SST is optional and a NOT_FOUND exception should never be
returned. BZ 716
Fixed a problem where a deleted object could be accessed from within the AML
parser. This was a regression introduced in version 20080123 as a fix for the
Unload operator. Lin Ming. BZ 10669
Cleaned up the debug operand dump mechanism. Eliminated unnecessary operands
and eliminated the use of a negative index in a loop. Operands are now
displayed in the correct order, not backwards. This also fixes a regression
introduced in 20080514 on 64-bit systems where the elimination of
ACPI_NATIVE_UINT caused the negative index to go large and positive. BZ 715
Fixed a possible memory leak in EvPciConfigRegionSetup where the error exit
path did not delete a locally allocated structure.
Updated definitions for the DMAR and SRAT tables to synchronize with the
current specifications. Includes disassembler support.
Fixed a problem in the mutex debug code (in utmutex.c) where an incorrect
loop termination value was used. Loop terminated on iteration early, missing
one mutex. Linn Crosetto
Example Code and Data Size: These are the sizes for the OS-independent
acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The
debug version of the code includes the debug output trace mechanism and has a
much larger code and data size.

Debug Version: 153.3K Code, 48.3K Data, 201.6K Total
Current Release:
Non-Debug Version: 79.3K Code, 16.2K Data, 95.5K Total
Debug Version: 153.0K Code, 48.2K Data, 201.2K Total
2) iASL Compiler/Disassembler and Tools:
Disassembler: Implemented support for EisaId() within _CID objects. Now
disassemble integer _CID objects back to EisaId invocations, including
multiple integers within _CID packages. Includes single-step support for
debugger also.
Disassembler: Added support for DMAR and SRAT table definition changes.
----------------------------------------
14 May 2008. Summary of changes for version 20080514:
1) ACPI CA Core Subsystem:
Fixed a problem where GPEs were enabled too early during the ACPICA
initialization. This could lead to "handler not installed" errors on some
machines. Moved GPE enable until after _REG/_STA/_INI methods are run. This
ensures that all operation regions and devices throughout the namespace have
been initialized before GPEs are enabled. Alexey Starikovskiy, BZ 9916.
Implemented a change to the enter sleep code. Moved execution of the _GTS
method to just before setting sleep enable bit. The execution was moved from
AcpiEnterSleepStatePrep to AcpiEnterSleepState. _GTS is now executed
immediately before the SLP_EN bit is set, as per the ACPI specification.
Luming Yu, BZ 1653.
Implemented a fix to disable unknown GPEs (2nd version). Now always disable
the GPE, even if ACPICA thinks that that it is already disabled. It is
possible that the AML or some other code has enabled the GPE unbeknownst to
the ACPICA code.
Fixed a problem with the Field operator where zero-length fields would return
an AE_AML_NO_OPERAND exception during table load. Fix enables zero-length ASL
field declarations in Field(), BankField(), and IndexField(). BZ 10606.
Implemented a fix for the Load operator, now load the table at the namespace
root. This reverts a change introduced in version 20071019. The table is now
loaded at the namespace root even though this goes against the ACPI
specification. This provides compatibility with other ACPI implementations.
The ACPI specification will be updated to reflect this in ACPI 4.0. Lin Ming.
Fixed a problem where ACPICA would not Load() tables with unusual signatures.
Now ignore ACPI table signature for Load() operator. Only "SSDT" is
acceptable to the ACPI spec, but tables are seen with OEMx and null sigs.
Therefore, signature validation is worthless. Apparently MS ACPI accepts such
signatures, ACPICA must be compatible. BZ 10454.
Fixed a possible negative array index in AcpiUtValidateException. Added NULL
fields to the exception string arrays to eliminate a -1 subtraction on the
SubStatus field.
Updated the debug tracking macros to reduce overall code and data size.
Changed ACPI_MODULE_NAME and ACPI_FUNCTION_NAME to use arrays of strings
instead of pointers to static strings. Jan Beulich and Bob Moore.
Implemented argument count checking in control method invocation via
AcpiEvaluateObject. Now emit an error if too few arguments, warning if too
many. This applies only to extern programmatic control method execution, not
method-to-method calls within the AML. Lin Ming.
Eliminated the ACPI_NATIVE_UINT type across all ACPICA code. This type is no
longer needed, especially with the removal of 16-bit support. It was replaced
mostly with UINT32, but also ACPI_SIZE where a type that changes 32/64 bit on
32/64-bit platforms is required.
Added the C const qualifier for appropriate string constants -- mostly
MODULE_NAME and printf format strings. Jan Beulich.
Example Code and Data Size: These are the sizes for the OS-independent
acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The
debug version of the code includes the debug output trace mechanism and has a
much larger code and data size.
Previous Release:
Non-Debug Version: 80.0K Code, 17.4K Data, 97.4K Total
Debug Version: 159.4K Code, 64.4K Data, 223.8K Total
Current Release:
Non-Debug Version: 79.5K Code, 16.2K Data, 95.7K Total
Debug Version: 153.3K Code, 48.3K Data, 201.6K Total
2) iASL Compiler/Disassembler and Tools:
Implemented ACPI table revision ID validation in the disassembler. Zero is
always invalid. For DSDTs, the ID controls the interpreter integer width. 1
means 32-bit and this is unusual. 2 or greater is 64-bit.
----------------------------------------
21 March 2008. Summary of changes for version 20080321:
1) ACPI CA Core Subsystem:
Implemented an additional change to the GPE support in order to suppress
spurious or stray GPEs. The AcpiEvDisableGpe function will now permanently
disable incoming GPEs that are neither enabled nor disabled -- meaning that
the GPE is unknown to the system. This should prevent future interrupt floods
from that GPE. BZ 6217 (Zhang Rui)
Fixed a problem where NULL package elements were not returned to the
AcpiEvaluateObject interface correctly. The element was simply ignored
instead of returning a NULL ACPI_OBJECT package element, potentially causing
a buffer overflow and/or confusing the caller who expected a fixed number of
elements. BZ 10132 (Lin Ming, Bob Moore)
Fixed a problem with the CreateField, CreateXXXField (Bit, Byte, Word, Dword,
Qword), Field, BankField, and IndexField operators when invoked from inside
an executing control method. In this case, these operators created namespace
nodes that were incorrectly left marked as permanent nodes instead of
temporary nodes. This could cause a problem if there is race condition
between an exiting control method and a running namespace walk. (Reported by
Linn Crosetto)
Fixed a problem where the CreateField and CreateXXXField operators would
incorrectly allow duplicate names (the name of the field) with no exception
generated.
Implemented several changes for Notify handling. Added support for new Notify
values (ACPI 2.0+) and improved the Notify debug output. Notify on
PowerResource objects is no longer allowed, as per the ACPI specification.
(Bob Moore, Zhang Rui)
All Reference Objects returned via the AcpiEvaluateObject interface are now
marked as type "REFERENCE" instead of "ANY". The type ANY is now reserved for
NULL objects - either NULL package elements or unresolved named references.
Fixed a problem where an extraneous debug message was produced for package
objects (when debugging enabled). The message "Package List length larger
than NumElements count" is now produced in the correct case, and is now an
error message rather than a debug message. Added a debug message for the
opposite case, where NumElements is larger than the Package List (the package
will be padded out with NULL elements as per the ACPI spec.)
Implemented several improvements for the output of the ASL "Debug" object to
clarify and keep all data for a given object on one output line.
Fixed two size calculation issues with the variable-length Start Dependent
resource descriptor.
Example Code and Data Size: These are the sizes for the OS-independent
acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The
debug version of the code includes the debug output trace mechanism and has
a much larger code and data size.
Previous Release:
Non-Debug Version: 79.7K Code, 17.3K Data, 97.0K Total
Debug Version: 158.9K Code, 64.0K Data, 222.9K Total
Current Release:
Non-Debug Version: 80.0K Code, 17.4K Data, 97.4K Total
Debug Version: 159.4K Code, 64.4K Data, 223.8K Total
2) iASL Compiler/Disassembler and Tools:
Fixed a problem with the use of the Switch operator where execution of the
containing method by multiple concurrent threads could cause an
AE_ALREADY_EXISTS exception. This is caused by the fact that there is no
actual Switch opcode, it must be simulated with local named temporary
variables and if/else pairs. The solution chosen was to mark any method that
uses Switch as Serialized, thus preventing multiple thread entries. BZ 469.
----------------------------------------
13 February 2008. Summary of changes for version 20080213:
1) ACPI CA Core Subsystem:
Implemented another MS compatibility design change for GPE/Notify handling.
GPEs are now cleared/enabled asynchronously to allow all pending notifies to
complete first. It is expected that the OSL will queue the enable request
behind all pending notify requests (may require changes to the local host OSL
in AcpiOsExecute). Alexey Starikovskiy.
Fixed a problem where buffer and package objects passed as arguments to a
control method via the external AcpiEvaluateObject interface could cause an
AE_AML_INTERNAL exception depending on the order and type of operators
executed by the target control method.
Fixed a problem where resource descriptor size optimization could cause a
problem when a _CRS resource template is passed to a _SRS method. The _SRS
resource template must use the same descriptors (with the same size) as
returned from _CRS. This change affects the following resource descriptors:
IRQ / IRQNoFlags and StartDependendentFn / StartDependentFnNoPri. (BZ 9487)
Fixed a problem where a CopyObject to RegionField, BankField, and IndexField
objects did not perform an implicit conversion as it should. These types must
retain their initial type permanently as per the ACPI specification. However,
a CopyObject to all other object types should not perform an implicit
conversion, as per the ACPI specification. (Lin Ming, Bob Moore) BZ 388
Fixed a problem with the AcpiGetDevices interface where the mechanism to
match device CIDs did not examine the entire list of available CIDs, but
instead aborted on the first non-matching CID. Andrew Patterson.
Fixed a regression introduced in version 20071114. The ACPI_HIDWORD macro was
inadvertently changed to return a 16-bit value instead of a 32-bit value,
truncating the upper dword of a 64-bit value. This macro is only used to
display debug output, so no incorrect calculations were made. Also,
reimplemented the macro so that a 64-bit shift is not performed by
inefficient compilers.
Added missing va_end statements that should correspond with each va_start
statement.
Example Code and Data Size: These are the sizes for the OS-independent
acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The
debug version of the code includes the debug output trace mechanism and has
a much larger code and data size.

Current Release:
Non-Debug Version: 79.7K Code, 17.3K Data, 97.0K Total
Debug Version: 158.9K Code, 64.0K Data, 222.9K Total
2) iASL Compiler/Disassembler and Tools:
Implemented full disassembler support for the following new ACPI tables:
BERT, EINJ, and ERST. Implemented partial disassembler support for the
complicated HEST table. These tables support the Windows Hardware Error
Architecture (WHEA).
----------------------------------------
23 January 2008. Summary of changes for version 20080123:
1) ACPI CA Core Subsystem:
Added the 2008 copyright to all module headers and signons. This affects
virtually every file in the ACPICA core subsystem, the iASL compiler, and
the tools/utilities.
Fixed a problem with the SizeOf operator when used with Package and Buffer
objects. These objects have deferred execution for some arguments, and the
execution is now completed before the SizeOf is executed. This problem caused
unexpected AE_PACKAGE_LIMIT errors on some systems (Lin Ming, Bob Moore) BZ
9558
Implemented an enhancement to the interpreter "slack mode". In the absence of
an explicit return or an implicitly returned object from the last executed
opcode, a control method will now implicitly return an integer of value 0 for
Microsoft compatibility. (Lin Ming) BZ 392
Fixed a problem with the Load operator where an exception was not returned in
the case where the table is already loaded. (Lin Ming) BZ 463
Implemented support for the use of DDBHandles as an Indexed Reference, as per
the ACPI spec. (Lin Ming) BZ 486
Implemented support for UserTerm (Method invocation) for the Unload operator
as per the ACPI spec. (Lin Ming) BZ 580
Fixed a problem with the LoadTable operator where the OemId and OemTableId
input strings could cause unexpected failures if they were shorter than the
maximum lengths allowed. (Lin Ming, Bob Moore) BZ 576
Implemented support for UserTerm (Method invocation) for the Unload operator
as per the ACPI spec. (Lin Ming) BZ 580
Implemented header file support for new ACPI tables - BERT, ERST, EINJ, HEST,
IBFT, UEFI, WDAT. Disassembler support is forthcoming.
Example Code and Data Size: These are the sizes for the OS-independent
acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The
debug version of the code includes the debug output trace mechanism and has
a much larger code and data size.

Non-Debug Version: 79.5K Code, 17.2K Data, 96.7K Total
Debug Version: 159.0K Code, 63.8K Data, 222.8K Total
2) iASL Compiler/Disassembler and Tools:
Implemented support in the disassembler for checksum validation on incoming
binary DSDTs and SSDTs. If incorrect, a message is displayed within the table
header dump at the start of the disassembly.
Implemented additional debugging information in the namespace listing file
created during compilation. In addition to the namespace hierarchy, the full
pathname to each namespace object is displayed.
Fixed a problem with the disassembler where invalid ACPI tables could cause
faults or infinite loops.
Fixed an unexpected parse error when using the optional "parameter types"
list in a control method declaration. (Lin Ming) BZ 397
Fixed a problem where two External declarations with the same name did not
cause an error (Lin Ming) BZ 509
Implemented support for full TermArgs (adding Argx, Localx and method
invocation) for the ParameterData parameter to the LoadTable operator. (Lin
Ming) BZ 583,587
----------------------------------------
19 December 2007. Summary of changes for version 20071219:
1) ACPI CA Core Subsystem:
Implemented full support for deferred execution for the TermArg string
arguments for DataTableRegion. This enables forward references and full
operand resolution for the three string arguments. Similar to OperationRegion
deferred argument execution.) Lin Ming. BZ 430
Implemented full argument resolution support for the BankValue argument to
BankField. Previously, only constants were supported, now any TermArg may be
used. Lin Ming BZ 387, 393
Fixed a problem with AcpiGetDevices where the search of a branch of the
device tree could be terminated prematurely. In accordance with the ACPI
specification, the search down the current branch is terminated if a device
is both not present and not functional (instead of just not present.) Yakui
Zhao.
Fixed a problem where "unknown" GPEs could be allowed to fire repeatedly if
the underlying AML code changed the GPE enable registers. Now, any unknown
incoming GPE (no _Lxx/_Exx method and not the EC GPE) is immediately disabled
instead of simply ignored. Rui Zhang.
Fixed a problem with Index Fields where the Index register was incorrectly
limited to a maximum of 32 bits. Now any size may be used.
Fixed a couple memory leaks associated with "implicit return" objects when
the AML Interpreter slack mode is enabled. Lin Ming BZ 349
Example Code and Data Size: These are the sizes for the OS-independent
acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The
debug version of the code includes the debug output trace mechanism and has
a much larger code and data size.

----------------------------------------
14 November 2007. Summary of changes for version 20071114:
1) ACPI CA Core Subsystem:
Implemented event counters for each of the Fixed Events, the ACPI SCI
(interrupt) itself, and control methods executed. Named
AcpiFixedEventCount[], AcpiSciCount, and AcpiMethodCount respectively. These
should be useful for debugging and statistics.
Implemented a new external interface, AcpiGetStatistics, to retrieve the
contents of the various event counters. Returns the current values for
AcpiSciCount, AcpiGpeCount, the AcpiFixedEventCount array, and
AcpiMethodCount. The interface can be expanded in the future if new counters
are added. Device drivers should use this interface rather than access the
counters directly.
Fixed a problem with the FromBCD and ToBCD operators. With some compilers,
the ShortDivide function worked incorrectly, causing problems with the BCD
functions with large input values. A truncation from 64-bit to 32-bit
inadvertently occurred. Internal BZ 435. Lin Ming
Fixed a problem with Index references passed as method arguments. References
passed as arguments to control methods were dereferenced immediately (before
control was passed to the called method). The references are now correctly
passed directly to the called method. BZ 5389. Lin Ming
Fixed a problem with CopyObject used in conjunction with the Index operator.
The reference was incorrectly dereferenced before the copy. The reference is
now correctly copied. BZ 5391. Lin Ming
Fixed a problem with Control Method references within Package objects. These
references are now correctly generated. This completes the package
construction overhaul that began in version 20071019.
Example Code and Data Size: These are the sizes for the OS-independent
acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The
debug version of the code includes the debug output trace mechanism and has
a much larger code and data size.

2) iASL Compiler/Disassembler and Tools:
The AcpiExec utility now installs handlers for all of the predefined
Operation Region types. New types supported are: PCI_Config, CMOS, and
PCIBARTarget.
Fixed a problem with the 64-bit version of AcpiExec where the extended (64-
bit) address fields for the DSDT and FACS within the FADT were not being
used, causing truncation of the upper 32-bits of these addresses. Lin Ming
and Bob Moore
----------------------------------------
19 October 2007. Summary of changes for version 20071019:
1) ACPI CA Core Subsystem:
Fixed a problem with the Alias operator when the target of the alias is a
named ASL operator that opens a new scope -- Scope, Device, PowerResource,
Processor, and ThermalZone. In these cases, any children of the original
operator could not be accessed via the alias, potentially causing unexpected
AE_NOT_FOUND exceptions. (BZ 9067)
Fixed a problem with the Package operator where all named references were
created as object references and left otherwise unresolved. According to the
ACPI specification, a Package can only contain Data Objects or references to
control methods. The implication is that named references to Data Objects
(Integer, Buffer, String, Package, BufferField, Field) should be resolved
immediately upon package creation. This is the approach taken with this
change. References to all other named objects (Methods, Devices, Scopes,
etc.) are all now properly created as reference objects. (BZ 5328)
Reverted a change to Notify handling that was introduced in version
20070508. This version changed the Notify handling from asynchronous to
fully synchronous (Device driver Notify handling with respect to the Notify
ASL operator). It was found that this change caused more problems than it
solved and was removed by most users.
Fixed a problem with the Increment and Decrement operators where the type of
the target object could be unexpectedly and incorrectly changed. (BZ 353)
Lin Ming.
Fixed a problem with the Load and LoadTable operators where the table
location within the namespace was ignored. Instead, the table was always
loaded into the root or current scope. Lin Ming.
Fixed a problem with the Load operator when loading a table from a buffer
object. The input buffer was prematurely zeroed and/or deleted. (BZ 577)
Fixed a problem with the Debug object where a store of a DdbHandle reference
object to the Debug object could cause a fault.
Added a table checksum verification for the Load operator, in the case where
the load is from a buffer. (BZ 578).
Implemented additional parameter validation for the LoadTable operator. The
length of the input strings SignatureString, OemIdString, and OemTableId are
now checked for maximum lengths. (BZ 582) Lin Ming.
Example Code and Data Size: These are the sizes for the OS-independent
acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The
debug version of the code includes the debug output trace mechanism and has
a much larger code and data size.

2) iASL Compiler/Disassembler:
Fixed a problem where if a single file was specified and the file did not
exist, no error message was emitted. (Introduced with wildcard support in
version 20070917.)
----------------------------------------
19 September 2007. Summary of changes for version 20070919:
1) ACPI CA Core Subsystem:
Designed and implemented new external interfaces to install and remove
handlers for ACPI table-related events. Current events that are defined are
LOAD and UNLOAD. These interfaces allow the host to track ACPI tables as
they are dynamically loaded and unloaded. See AcpiInstallTableHandler and
AcpiRemoveTableHandler. (Lin Ming and Bob Moore)
Fixed a problem where the use of the AcpiGbl_AllMethodsSerialized flag
(acpi_serialized option on Linux) could cause some systems to hang during
initialization. (Bob Moore) BZ 8171
Fixed a problem where objects of certain types (Device, ThermalZone,
Processor, PowerResource) can be not found if they are declared and
referenced from within the same control method (Lin Ming) BZ 341
Example Code and Data Size: These are the sizes for the OS-independent
acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The

2) iASL Compiler/Disassembler:
Implemented support to allow multiple files to be compiled/disassembled in a
single invocation. This includes command line wildcard support for both the
Windows and Unix versions of the compiler. This feature simplifies the
disassembly and compilation of multiple ACPI tables in a single directory.
----------------------------------------
08 May 2007. Summary of changes for version 20070508:
1) ACPI CA Core Subsystem:
Implemented a Microsoft compatibility design change for the handling of the
Notify AML operator. Previously, notify handlers were dispatched and
executed completely asynchronously in a deferred thread. The new design
still executes the notify handlers in a different thread, but the original
thread that executed the Notify() now waits at a synchronization point for
the notify handler to complete. Some machines depend on a synchronous Notify
operator in order to operate correctly.
Implemented support to allow Package objects to be passed as method
arguments to the external AcpiEvaluateObject interface. Previously, this
would return the AE_NOT_IMPLEMENTED exception. This feature had not been
implemented since there were no reserved control methods that required it
until recently.
Fixed a problem with the internal FADT conversion where ACPI 1.0 FADTs that
contained invalid non-zero values in reserved fields could cause later
failures because these fields have meaning in later revisions of the FADT.
For incoming ACPI 1.0 FADTs, these fields are now always zeroed. (The fields
are: Preferred_PM_Profile, PSTATE_CNT, CST_CNT, and IAPC_BOOT_FLAGS.)
Fixed a problem where the Global Lock handle was not properly updated if a
thread that acquired the Global Lock via executing AML code then attempted
to acquire the lock via the AcpiAcquireGlobalLock interface. Reported by Joe
Liu.
Fixed a problem in AcpiEvDeleteGpeXrupt where the global interrupt list
could be corrupted if the interrupt being removed was at the head of the
list. Reported by Linn Crosetto.

acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The

----------------------------------------
20 March 2007. Summary of changes for version 20070320:
1) ACPI CA Core Subsystem:
Implemented a change to the order of interpretation and evaluation of AML
operand objects within the AML interpreter. The interpreter now evaluates
operands in the order that they appear in the AML stream (and the
corresponding ASL code), instead of in the reverse order (after the entire
operand list has been parsed). The previous behavior caused several subtle
incompatibilities with the Microsoft AML interpreter as well as being
somewhat non-intuitive. BZ 7871, local BZ 263. Valery Podrezov.
Implemented a change to the ACPI Global Lock support. All interfaces to the
global lock now allow the same thread to acquire the lock multiple times.
This affects the AcpiAcquireGlobalLock external interface to the global lock
as well as the internal use of the global lock to support AML fields -- a
control method that is holding the global lock can now simultaneously access
AML fields that require global lock protection. Previously, in both cases,
this would have resulted in an AE_ALREADY_ACQUIRED exception. The change to
AcpiAcquireGlobalLock is of special interest to drivers for the Embedded
Controller. There is no change to the behavior of the AML Acquire operator,
as this can already be used to acquire a mutex multiple times by the same
thread. BZ 8066. With assistance from Alexey Starikovskiy.
Fixed a problem where invalid objects could be referenced in the AML
Interpreter after error conditions. During operand evaluation, ensure that
the internal "Return Object" field is cleared on error and only valid
pointers are stored there. Caused occasional access to deleted objects that
resulted in "large reference count" warning messages. Valery Podrezov.
Fixed a problem where an AE_STACK_OVERFLOW internal exception could occur on
deeply nested control method invocations. BZ 7873, local BZ 487. Valery
Podrezov.
Fixed an internal problem with the handling of result objects on the
interpreter result stack. BZ 7872. Valery Podrezov.
Removed obsolete code that handled the case where AML_NAME_OP is the target
of a reference (Reference.Opcode). This code was no longer necessary. BZ
7874. Valery Podrezov.
Removed obsolete ACPI_NO_INTEGER64_SUPPORT from two header files. This was a
remnant from the previously discontinued 16-bit support.
Example Code and Data Size: These are the sizes for the OS-independent
acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The
debug version of the code includes the debug output trace mechanism and has
a much larger code and data size.

----------------------------------------
26 January 2007. Summary of changes for version 20070126:
1) ACPI CA Core Subsystem:
Added the 2007 copyright to all module headers and signons. This affects
virtually every file in the ACPICA core subsystem, the iASL compiler, and
the utilities.
Implemented a fix for an incorrect parameter passed to AcpiTbDeleteTable
during a table load. A bad pointer was passed in the case where the DSDT is
overridden, causing a fault in this case.
Example Code and Data Size: These are the sizes for the OS-independent
acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The

----------------------------------------
15 December 2006. Summary of changes for version 20061215:
1) ACPI CA Core Subsystem:
Support for 16-bit ACPICA has been completely removed since it is no longer
necessary and it clutters the code. All 16-bit macros, types, and
conditional compiles have been removed, cleaning up and simplifying the code
across the entire subsystem. DOS support is no longer needed since the
bootable Linux firmware kit is now available.
The handler for the Global Lock is now removed during AcpiTerminate to
enable a clean subsystem restart, via the implementation of the
AcpiEvRemoveGlobalLockHandler function. (With assistance from Joel Bretz,
HP)
Implemented enhancements to the multithreading support within the debugger
to enable improved multithreading debugging and evaluation of the subsystem.
(Valery Podrezov)
Debugger: Enhanced the Statistics/Memory command to emit the total (maximum)
memory used during the execution, as well as the maximum memory consumed by
each of the various object types. (Valery Podrezov)
Example Code and Data Size: These are the sizes for the OS-independent
acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The
debug version of the code includes the debug output trace mechanism and has
a much larger code and data size.

Non-Debug Version: 78.0K Code, 17.1K Data, 95.1K Total
Debug Version: 155.8K Code, 63.3K Data, 219.1K Total
2) iASL Compiler/Disassembler and Tools:
AcpiExec: Implemented a new option (-m) to display full memory use
statistics upon subsystem/program termination. (Valery Podrezov)
----------------------------------------
09 November 2006. Summary of changes for version 20061109:
1) ACPI CA Core Subsystem:
Optimized the Load ASL operator in the case where the source operand is an
operation region. Simply map the operation region memory, instead of
performing a bytewise read. (Region must be of type SystemMemory, see
below.)
Fixed the Load ASL operator for the case where the source operand is a
region field. A buffer object is also allowed as the source operand. BZ 480
Fixed a problem where the Load ASL operator allowed the source operand to be
an operation region of any type. It is now restricted to regions of type
SystemMemory, as per the ACPI specification. BZ 481
Additional cleanup and optimizations for the new Table Manager code.
AcpiEnable will now fail if all of the required ACPI tables are not loaded
(FADT, FACS, DSDT). BZ 477
Added #pragma pack(8/4) to acobject.h to ensure that the structures in this
header are always compiled as aligned. The ACPI_OPERAND_OBJECT has been
manually optimized to be aligned and will not work if it is byte-packed.
Example Code and Data Size: These are the sizes for the OS-independent
acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The
debug version of the code includes the debug output trace mechanism and has
a much larger code and data size.

Current Release:
Non-Debug Version: 77.9K Code, 17.0K Data, 94.9K Total
Debug Version: 155.2K Code, 63.1K Data, 218.3K Total
2) iASL Compiler/Disassembler and Tools:
Fixed a problem where the presence of the _OSI predefined control method
within complex expressions could cause an internal compiler error.
AcpiExec: Implemented full region support for multiple address spaces.
SpaceId is now part of the REGION object. BZ 429
----------------------------------------
11 October 2006. Summary of changes for version 20061011:
1) ACPI CA Core Subsystem:
Completed an AML interpreter performance enhancement for control method
execution. Previously a 2-pass parse/execution, control methods are now
completely parsed and executed in a single pass. This improves overall
interpreter performance by ~25%, reduces code size, and reduces CPU stack
use. (Valery Podrezov + interpreter changes in version 20051202 that
eliminated namespace loading during the pass one parse.)
Implemented _CID support for PCI Root Bridge detection. If the _HID does not
match the predefined PCI Root Bridge IDs, the _CID list (if present) is now
obtained and also checked for an ID match.
Implemented additional support for the PCI _ADR execution: upsearch until a
device scope is found before executing _ADR. This allows PCI_Config
operation regions to be declared locally within control methods underneath
PCI device objects.
Fixed a problem with a possible race condition between threads executing
AcpiWalkNamespace and the AML interpreter. This condition was removed by
modifying AcpiWalkNamespace to (by default) ignore all temporary namespace
entries created during any concurrent control method execution. An
additional namespace race condition is known to exist between
AcpiWalkNamespace and the Load/Unload ASL operators and is still under
investigation.
Restructured the AML ParseLoop function, breaking it into several
subfunctions in order to reduce CPU stack use and improve maintainability.
(Mikhail Kouzmich)
AcpiGetHandle: Fix for parameter validation to detect invalid combinations
of prefix handle and pathname. BZ 478
Example Code and Data Size: These are the sizes for the OS-independent
acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The
debug version of the code includes the debug output trace mechanism and has
a much larger code and data size.

Debug Version: 155.4K Code, 63.1K Data, 218.5K Total
2) iASL Compiler/Disassembler and Tools:
Ported the -g option (get local ACPI tables) to the new ACPICA Table Manager
to restore original behavior.
----------------------------------------
27 September 2006. Summary of changes for version 20060927:
1) ACPI CA Core Subsystem:
Removed the "Flags" parameter from AcpiGetRegister and AcpiSetRegister.
These functions now use a spinlock for mutual exclusion and the interrupt
level indication flag is not needed.
Fixed a problem with the Global Lock where the lock could appear to be
obtained before it is actually obtained. The global lock semaphore was
inadvertently created with one unit instead of zero units. (BZ 464) Fiodor
Suietov.
Fixed a possible memory leak and fault in AcpiExResolveObjectToValue during
a read from a buffer or region field. (BZ 458) Fiodor Suietov.
Example Code and Data Size: These are the sizes for the OS-independent
acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The
debug version of the code includes the debug output trace mechanism and has
a much larger code and data size.

Current Release:
Non-Debug Version: 77.9K Code, 17.1K Data, 95.0K Total
Debug Version: 154.6K Code, 63.0K Data, 217.6K Total
2) iASL Compiler/Disassembler and Tools:
Fixed a compilation problem with the pre-defined Resource Descriptor field
names where an "object does not exist" error could be incorrectly generated
if the parent ResourceTemplate pathname places the template within a
different namespace scope than the current scope. (BZ 7212)
Fixed a problem where the compiler could hang after syntax errors detected
in an ElseIf construct. (BZ 453)
Fixed a problem with the AmlFilename parameter to the DefinitionBlock()
operator. An incorrect output filename was produced when this parameter was
a null string (""). Now, the original input filename is used as the AML
output filename, with an ".aml" extension.
Implemented a generic batch command mode for the AcpiExec utility (execute
any AML debugger command) (Valery Podrezov).
----------------------------------------
12 September 2006. Summary of changes for version 20060912:
1) ACPI CA Core Subsystem:
Enhanced the implementation of the "serialized mode" of the interpreter
(enabled via the AcpiGbl_AllMethodsSerialized flag.) When this mode is
specified, instead of creating a serialization semaphore per control method,
the interpreter lock is simply no longer released before a blocking
operation during control method execution. This effectively makes the AML
Interpreter single-threaded. The overhead of a semaphore per-method is
eliminated.
Fixed a regression where an error was no longer emitted if a control method
attempts to create 2 objects of the same name. This once again returns
AE_ALREADY_EXISTS. When this exception occurs, it invokes the mechanism that
will dynamically serialize the control method to possible prevent future
errors. (BZ 440)
Integrated a fix for a problem with PCI Express HID detection in the PCI
Config Space setup procedure. (BZ 7145)
Moved all FADT-related functions to a new file, tbfadt.c. Eliminated the
AcpiHwInitialize function - the FADT registers are now validated when the
table is loaded.
Added two new warnings during FADT verification - 1) if the FADT is larger
than the largest known FADT version, and 2) if there is a mismatch between a
32-bit block address and the 64-bit X counterpart (when both are non-zero.)
Example Code and Data Size: These are the sizes for the OS-independent
acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The
debug version of the code includes the debug output trace mechanism and has
a much larger code and data size.
Previous Release:
Non-Debug Version: 77.9K Code, 16.7K Data, 94.6K Total
Debug Version: 154.9K Code, 62.6K Data, 217.5K Total
Current Release:
Non-Debug Version: 77.9K Code, 17.1K Data, 95.0K Total
Debug Version: 154.7K Code, 63.0K Data, 217.7K Total
2) iASL Compiler/Disassembler and Tools:
Fixed a problem with the implementation of the Switch() operator where the
temporary variable was declared too close to the actual Switch, instead of
at method level. This could cause a problem if the Switch() operator is
within a while loop, causing an error on the second iteration. (BZ 460)
Disassembler - fix for error emitted for unknown type for target of scope
operator. Now, ignore it and continue.
Disassembly of an FADT now verifies the input FADT and reports any errors
found. Fix for proper disassembly of full-sized (ACPI 2.0) FADTs.
Disassembly of raw data buffers with byte initialization data now prefixes
each output line with the current buffer offset.
Disassembly of ASF! table now includes all variable-length data fields at
the end of some of the subtables.
The disassembler now emits a comment if a buffer appears to be a
ResourceTemplate, but cannot be disassembled as such because the EndTag does
not appear at the very end of the buffer.
AcpiExec - Added the "-t" command line option to enable the serialized mode
of the AML interpreter.
----------------------------------------
31 August 2006. Summary of changes for version 20060831:
1) ACPI CA Core Subsystem:
Miscellaneous fixes for the Table Manager:
- Correctly initialize internal common FADT for all 64-bit "X" fields
- Fixed a couple table mapping issues during table load
- Fixed a couple alignment issues for IA64
- Initialize input array to zero in AcpiInitializeTables
- Additional parameter validation for AcpiGetTable, AcpiGetTableHeader,
AcpiGetTableByIndex
Change for GPE support: when a "wake" GPE is received, all wake GPEs are now
immediately disabled to prevent the waking GPE from firing again and to
prevent other wake GPEs from interrupting the wake process.
Added the AcpiGpeCount global that tracks the number of processed GPEs, to
be used for debugging systems with a large number of ACPI interrupts.
Implemented support for the "DMAR" ACPI table (DMA Redirection Table) in
both the ACPICA headers and the disassembler.
Example Code and Data Size: These are the sizes for the OS-independent
acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The
debug version of the code includes the debug output trace mechanism and has
a much larger code and data size.

Disassembler support for the DMAR ACPI table.
----------------------------------------
23 August 2006. Summary of changes for version 20060823:
1) ACPI CA Core Subsystem:
The Table Manager component has been completely redesigned and
reimplemented. The new design is much simpler, and reduces the overall code
and data size of the kernel-resident ACPICA by approximately 5%. Also, it is
now possible to obtain the ACPI tables very early during kernel
initialization, even before dynamic memory management is initialized.
(Alexey Starikovskiy, Fiodor Suietov, Bob Moore)
Obsolete ACPICA interfaces:
- AcpiGetFirmwareTable: Use AcpiGetTable instead (works at early kernel init
time).
- AcpiLoadTable: Not needed.
- AcpiUnloadTable: Not needed.
New ACPICA interfaces:
- AcpiInitializeTables: Must be called before the table manager can be used.
- AcpiReallocateRootTable: Used to transfer the root table to dynamically
allocated memory after it becomes available.
- AcpiGetTableByIndex: Allows the host to easily enumerate all ACPI tables
in the RSDT/XSDT.
Other ACPICA changes:
- AcpiGetTableHeader returns the actual mapped table header, not a copy. Use
AcpiOsUnmapMemory to free this mapping.
- AcpiGetTable returns the actual mapped table. The mapping is managed
internally and must not be deleted by the caller. Use of this interface
causes no additional dynamic memory allocation.
- AcpiFindRootPointer: Support for physical addressing has been eliminated,
it appeared to be unused.
- The interface to AcpiOsMapMemory has changed to be consistent with the
other allocation interfaces.
- The interface to AcpiOsGetRootPointer has changed to eliminate unnecessary
parameters.
- ACPI_PHYSICAL_ADDRESS is now 32 bits on 32-bit platforms, 64 bits on 64-
bit platforms. Was previously 64 bits on all platforms.
- The interface to the ACPI Global Lock acquire/release macros have changed
slightly since ACPICA no longer keeps a local copy of the FACS with a
constructed pointer to the actual global lock.
Porting to the new table manager:
- AcpiInitializeTables: Must be called once, and can be called anytime
during the OS initialization process. It allows the host to specify an area
of memory to be used to store the internal version of the RSDT/XSDT (root
table). This allows the host to access ACPI tables before memory management
is initialized and running.
- AcpiReallocateRootTable: Can be called after memory management is running
to copy the root table to a dynamically allocated array, freeing up the
scratch memory specified in the call to AcpiInitializeTables.
- AcpiSubsystemInitialize: This existing interface is independent of the
Table Manager, and does not have to be called before the Table Manager can
be used, it only must be called before the rest of ACPICA can be used.
- ACPI Tables: Some changes have been made to the names and structure of the
actbl.h and actbl1.h header files and may require changes to existing code.
For example, bitfields have been completely removed because of their lack of
portability across C compilers.
- Update interfaces to the Global Lock acquire/release macros if local
versions are used. (see acwin.h)
Obsolete files: tbconvrt.c, tbget.c, tbgetall.c, tbrsdt.c
New files: tbfind.c
Example Code and Data Size: These are the sizes for the OS-independent
acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The
debug version of the code includes the debug output trace mechanism and has
a much larger code and data size.

----------------------------------------
21 July 2006. Summary of changes for version 20060721:
1) ACPI CA Core Subsystem:
The full source code for the ASL test suite used to validate the iASL
compiler and the ACPICA core subsystem is being released with the ACPICA
source for the first time. The source is contained in a separate package and
consists of over 1100 files that exercise all ASL/AML operators. The package
should appear on the Intel/ACPI web site shortly. (Valery Podrezov, Fiodor
Suietov)
Completed a new design and implementation for support of the ACPI Global
Lock. On the OS side, the global lock is now treated as a standard AML
mutex. Previously, multiple OS threads could "acquire" the global lock
simultaneously. However, this could cause the BIOS to be starved out of the
lock - especially in cases such as the Embedded Controller driver where
there is a tight coupling between the OS and the BIOS.
Implemented an optimization for the ACPI Global Lock interrupt mechanism.
The Global Lock interrupt handler no longer queues the execution of a
separate thread to signal the global lock semaphore. Instead, the semaphore
is signaled directly from the interrupt handler.
Implemented support within the AML interpreter for package objects that
contain a larger AML length (package list length) than the package element
count. In this case, the length of the package is truncated to match the
package element count. Some BIOS code apparently modifies the package length
on the fly, and this change supports this behavior. Provides compatibility
with the MS AML interpreter. (With assistance from Fiodor Suietov)
Implemented a temporary fix for the BankValue parameter of a Bank Field to
support all constant values, now including the Zero and One opcodes.
Evaluation of this parameter must eventually be converted to a full TermArg
evaluation. A not-implemented error is now returned (temporarily) for non-
constant values for this parameter.
Fixed problem reports (Fiodor Suietov) integrated:
- Fix for premature object deletion after CopyObject on Operation Region (BZ
350)
Example Code and Data Size: These are the sizes for the OS-independent
acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The
debug version of the code includes the debug output trace mechanism and has
a much larger code and data size.

No changes for this release.
----------------------------------------
07 July 2006. Summary of changes for version 20060707:
1) ACPI CA Core Subsystem:
Added the ACPI_PACKED_POINTERS_NOT_SUPPORTED macro to support C compilers
that do not allow the initialization of address pointers within packed
structures - even though the hardware itself may support misaligned
transfers. Some of the debug data structures are packed by default to
minimize size.
Added an error message for the case where AcpiOsGetThreadId() returns zero.
A non-zero value is required by the core ACPICA code to ensure the proper
operation of AML mutexes and recursive control methods.
The DSDT is now the only ACPI table that determines whether the AML
interpreter is in 32-bit or 64-bit mode. Not really a functional change, but
the hooks for per-table 32/64 switching have been removed from the code. A
clarification to the ACPI specification is forthcoming in ACPI 3.0B.
Fixed a possible leak of an OwnerID in the error path of
AcpiTbInitTableDescriptor (tbinstal.c), and migrated all table OwnerID
deletion to a single place in AcpiTbUninstallTable to correct possible leaks
when using the AcpiTbDeleteTablesByType interface (with assistance from
Lance Ortiz.)
Fixed a problem with Serialized control methods where the semaphore
associated with the method could be over-signaled after multiple method
invocations.
Fixed two issues with the locking of the internal namespace data structure.
Both the Unload() operator and AcpiUnloadTable interface now lock the
namespace during the namespace deletion associated with the table unload
(with assistance from Linn Crosetto.)
Fixed problem reports (Valery Podrezov) integrated:
- Eliminate unnecessary memory allocation for CreateXxxxField (BZ 5426)
Fixed problem reports (Fiodor Suietov) integrated:
- Incomplete cleanup branches in AcpiTbGetTableRsdt (BZ 369)
- On Address Space handler deletion, needless deactivation call (BZ 374)
- AcpiRemoveAddressSpaceHandler: validate Device handle parameter (BZ 375)
- Possible memory leak, Notify sub-objects of Processor, Power, ThermalZone
(BZ 376)
- AcpiRemoveAddressSpaceHandler: validate Handler parameter (BZ 378)
- Minimum Length of RSDT should be validated (BZ 379)
- AcpiRemoveNotifyHandler: return AE_NOT_EXIST if Processor Obj has no
Handler (BZ (380)
- AcpiUnloadTable: return AE_NOT_EXIST if no table of specified type loaded
(BZ 381)
Example Code and Data Size: These are the sizes for the OS-independent

----------------------------------------
23 June 2006. Summary of changes for version 20060623:
1) ACPI CA Core Subsystem:
Implemented a new ACPI_SPINLOCK type for the OSL lock interfaces. This
allows the type to be customized to the host OS for improved efficiency
(since a spinlock is usually a very small object.)
Implemented support for "ignored" bits in the ACPI registers. According to
the ACPI specification, these bits should be preserved when writing the
registers via a read/modify/write cycle. There are 3 bits preserved in this
manner: PM1_CONTROL[0] (SCI_EN), PM1_CONTROL[9], and PM1_STATUS[11].
Implemented the initial deployment of new OSL mutex interfaces. Since some
host operating systems have separate mutex and semaphore objects, this
feature was requested. The base code now uses mutexes (and the new mutex
interfaces) wherever a binary semaphore was used previously. However, for
the current release, the mutex interfaces are defined as macros to map them
to the existing semaphore interfaces. Therefore, no OSL changes are required
at this time. (See acpiosxf.h)
Fixed several problems with the support for the control method SyncLevel
parameter. The SyncLevel now works according to the ACPI specification and
in concert with the Mutex SyncLevel parameter, since the current SyncLevel
is a property of the executing thread. Mutual exclusion for control methods
is now implemented with a mutex instead of a semaphore.
Fixed three instances of the use of the C shift operator in the bitfield
support code (exfldio.c) to avoid the use of a shift value larger than the
target data width. The behavior of C compilers is undefined in this case and
can cause unpredictable results, and therefore the case must be detected and
avoided. (Fiodor Suietov)
Added an info message whenever an SSDT or OEM table is loaded dynamically
via the Load() or LoadTable() ASL operators. This should improve debugging
capability since it will show exactly what tables have been loaded (beyond
the tables present in the RSDT/XSDT.)
Example Code and Data Size: These are the sizes for the OS-independent
acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The
debug version of the code includes the debug output trace mechanism and has
a much larger code and data size.

----------------------------------------
08 June 2006. Summary of changes for version 20060608:
1) ACPI CA Core Subsystem:
Converted the locking mutex used for the ACPI hardware to a spinlock. This
change should eliminate all problems caused by attempting to acquire a
semaphore at interrupt level, and it means that all ACPICA external
interfaces that directly access the ACPI hardware can be safely called from
interrupt level. OSL code that implements the semaphore interfaces should be
able to eliminate any workarounds for being called at interrupt level.
Fixed a regression introduced in 20060526 where the ACPI device
initialization could be prematurely aborted with an AE_NOT_FOUND if a device
did not have an optional _INI method.
Fixed an IndexField issue where a write to the Data Register should be
limited in size to the AccessSize (width) of the IndexField itself. (BZ 433,
Fiodor Suietov)
Fixed problem reports (Valery Podrezov) integrated:
- Allow store of ThermalZone objects to Debug object (BZ 5369/5370)
Fixed problem reports (Fiodor Suietov) integrated:
- AcpiGetTableHeader doesn't handle multiple instances correctly (BZ 364)
Removed four global mutexes that were obsolete and were no longer being
used.
Example Code and Data Size: These are the sizes for the OS-independent
acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The
debug version of the code includes the debug output trace mechanism and has
a much larger code and data size.

machines.
Fixed problem reports integrated:
- Generate error if CreateField NumBits parameter is zero. (BZ 405)
- Fault if Offset/Length in Field unit is very large (BZ 432, Fiodor
Suietov)
- Global table revision override (-r) is ignored (BZ 413)
----------------------------------------
26 May 2006. Summary of changes for version 20060526:
1) ACPI CA Core Subsystem:
Restructured, flattened, and simplified the internal interfaces for
namespace object evaluation - resulting in smaller code, less CPU stack use,
and fewer interfaces. (With assistance from Mikhail Kouzmich)
Fixed a problem with the CopyObject operator where the first parameter was
not typed correctly for the parser, interpreter, compiler, and disassembler.
Caused various errors and unexpected behavior.
Fixed a problem where a ShiftLeft or ShiftRight of more than 64 bits
produced incorrect results with some C compilers. Since the behavior of C
compilers when the shift value is larger than the datatype width is
apparently not well defined, the interpreter now detects this condition and
simply returns zero as expected in all such cases. (BZ 395)
Fixed problem reports (Valery Podrezov) integrated:
- Update String-to-Integer conversion to match ACPI 3.0A spec (BZ 5329)
- Allow interpreter to handle nested method declarations (BZ 5361)
Fixed problem reports (Fiodor Suietov) integrated:
- AcpiTerminate doesn't free debug memory allocation list objects (BZ 355)
- After Core Subsystem shutdown, AcpiSubsystemStatus returns AE_OK (BZ 356)
- AcpiOsUnmapMemory for RSDP can be invoked inconsistently (BZ 357)
- Resource Manager should return AE_TYPE for non-device objects (BZ 358)
- Incomplete cleanup branch in AcpiNsEvaluateRelative (BZ 359)
- Use AcpiOsFree instead of ACPI_FREE in AcpiRsSetSrsMethodData (BZ 360)
- Incomplete cleanup branch in AcpiPsParseAml (BZ 361)
- Incomplete cleanup branch in AcpiDsDeleteWalkState (BZ 362)
- AcpiGetTableHeader returns AE_NO_ACPI_TABLES until DSDT is loaded (BZ 365)
- Status of the Global Initialization Handler call not used (BZ 366)
- Incorrect object parameter to Global Initialization Handler (BZ 367)
Example Code and Data Size: These are the sizes for the OS-independent
acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The
debug version of the code includes the debug output trace mechanism and has
a much larger code and data size.

Debug Version: 160.3K Code, 64.9K Data, 225.2K Total
2) iASL Compiler/Disassembler and Tools:
Modified the parser to allow the names IO, DMA, and IRQ to be used as
namespace identifiers with no collision with existing resource descriptor
macro names. This provides compatibility with other ASL compilers and is
most useful for disassembly/recompilation of existing tables without parse
errors. (With assistance from Thomas Renninger)
Disassembler: fixed an incorrect disassembly problem with the
DataTableRegion and CopyObject operators. Fixed a possible fault during
disassembly of some Alias operators.
----------------------------------------
12 May 2006. Summary of changes for version 20060512:
1) ACPI CA Core Subsystem:
Replaced the AcpiOsQueueForExecution interface with a new interface named
AcpiOsExecute. The major difference is that the new interface does not have
a Priority parameter, this appeared to be useless and has been replaced by a
Type parameter. The Type tells the host what type of execution is being
requested, such as global lock handler, notify handler, GPE handler, etc.
This allows the host to queue and execute the request as appropriate for the
request type, possibly using different work queues and different priorities
for the various request types. This enables fixes for multithreading
deadlock problems such as BZ #5534, and will require changes to all existing
OS interface layers. (Alexey Starikovskiy and Bob Moore)
Fixed a possible memory leak associated with the support for the so-called
"implicit return" ACPI extension. Reported by FreeBSD, BZ #6514. (Fiodor
Suietov)
Fixed a problem with the Load() operator where a table load from an
operation region could overwrite an internal table buffer by up to 7 bytes
and cause alignment faults on IPF systems. (With assistance from Luming Yu)
Example Code and Data Size: These are the sizes for the OS-independent
acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The
debug version of the code includes the debug output trace mechanism and has
a much larger code and data size.

Current Release:
Non-Debug Version: 79.8K Code, 17.7K Data, 97.5K Total
Debug Version: 160.5K Code, 65.1K Data, 225.6K Total
2) iASL Compiler/Disassembler and Tools:
Disassembler: Implemented support to cross reference the internal namespace
and automatically generate ASL External() statements for symbols not defined
within the current table being disassembled. This will simplify the
disassembly and recompilation of interdependent tables such as SSDTs since
these statements will no longer have to be added manually.
Disassembler: Implemented experimental support to automatically detect
invocations of external control methods and generate appropriate External()
statements. This is problematic because the AML cannot be correctly parsed
until the number of arguments for each control method is known. Currently,
standalone method invocations and invocations as the source operand of a
Store() statement are supported.
Disassembler: Implemented support for the ASL pseudo-operators LNotEqual,
LLessEqual, and LGreaterEqual. Previously disassembled as LNot(LEqual()),
LNot(LGreater()), and LNot(LLess()), this makes the disassembled ASL code
more readable and likely closer to the original ASL source.
----------------------------------------
21 April 2006. Summary of changes for version 20060421:
1) ACPI CA Core Subsystem:
Removed a device initialization optimization introduced in 20051216 where
the _STA method was not run unless an _INI was also present for the same
device. This optimization could cause problems because it could allow _INI
methods to be run within a not-present device subtree. (If a not-present
device had no _INI, _STA would not be run, the not-present status would not
be discovered, and the children of the device would be incorrectly
traversed.)
Implemented a new _STA optimization where namespace subtrees that do not
contain _INI are identified and ignored during device initialization.
Selectively running _STA can significantly improve boot time on large
machines (with assistance from Len Brown.)
Implemented support for the device initialization case where the returned
_STA flags indicate a device not-present but functioning. In this case, _INI
is not run, but the device children are examined for presence, as per the
ACPI specification.
Implemented an additional change to the IndexField support in order to
conform to MS behavior. The value written to the Index Register is not
simply a byte offset, it is a byte offset in units of the access width of
the parent Index Field. (Fiodor Suietov)
Defined and deployed a new OSL interface, AcpiOsValidateAddress. This
interface is called during the creation of all AML operation regions, and
allows the host OS to exert control over what addresses it will allow the
AML code to access. Operation Regions whose addresses are disallowed will
cause a runtime exception when they are actually accessed (will not affect
or abort table loading.) See oswinxf or osunixxf for an example
implementation.
Defined and deployed a new OSL interface, AcpiOsValidateInterface. This
interface allows the host OS to match the various "optional"
interface/behavior strings for the _OSI predefined control method as
appropriate (with assistance from Bjorn Helgaas.) See oswinxf or osunixxf
for an example implementation.
Restructured and corrected various problems in the exception handling code
paths within DsCallControlMethod and DsTerminateControlMethod in dsmethod
(with assistance from Takayoshi Kochi.)
Modified the Linux source converter to ignore quoted string literals while
converting identifiers from mixed to lower case. This will correct problems
with the disassembler and other areas where such strings must not be
modified.
The ACPI_FUNCTION_* macros no longer require quotes around the function
name. This allows the Linux source converter to convert the names, now that
the converter ignores quoted strings.
Example Code and Data Size: These are the sizes for the OS-independent
acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The
debug version of the code includes the debug output trace mechanism and has
a much larger code and data size.

Current Release:
Non-Debug Version: 79.7K Code, 17.7K Data, 97.4K Total
Debug Version: 160.1K Code, 65.2K Data, 225.3K Total
2) iASL Compiler/Disassembler and Tools:
Implemented 3 new warnings for iASL, and implemented multiple warning levels
(w2 flag).
1) Ignored timeouts: If the TimeoutValue parameter to Wait or Acquire is not
WAIT_FOREVER (0xFFFF) and the code does not examine the return value to
check for the possible timeout, a warning is issued.
2) Useless operators: If an ASL operator does not specify an optional target
operand and it also does not use the function return value from the
operator, a warning is issued since the operator effectively does nothing.
3) Unreferenced objects: If a namespace object is created, but never
referenced, a warning is issued. This is a warning level 2 since there are
cases where this is ok, such as when a secondary table is loaded that uses
the unreferenced objects. Even so, care is taken to only flag objects that
don't look like they will ever be used. For example, the reserved methods
(starting with an underscore) are usually not referenced because it is
expected that the OS will invoke them.
----------------------------------------
31 March 2006. Summary of changes for version 20060331:
1) ACPI CA Core Subsystem:
Implemented header file support for the following additional ACPI tables:
ASF!, BOOT, CPEP, DBGP, MCFG, SPCR, SPMI, TCPA, and WDRT. With this support,
all current and known ACPI tables are now defined in the ACPICA headers and
are available for use by device drivers and other software.
Implemented support to allow tables that contain ACPI names with invalid
characters to be loaded. Previously, this would cause the table load to
fail, but since there are several known cases of such tables on existing
machines, this change was made to enable ACPI support for them. Also, this
matches the behavior of the Microsoft ACPI implementation.
Fixed a couple regressions introduced during the memory optimization in the
20060317 release. The namespace node definition required additional
reorganization and an internal datatype that had been changed to 8-bit was
restored to 32-bit. (Valery Podrezov)
Fixed a problem where a null pointer passed to AcpiUtDeleteGenericState
could be passed through to AcpiOsReleaseObject which is unexpected. Such
null pointers are now trapped and ignored, matching the behavior of the
previous implementation before the deployment of AcpiOsReleaseObject.
(Valery Podrezov, Fiodor Suietov)
Fixed a memory mapping leak during the deletion of a SystemMemory operation
region where a cached memory mapping was not deleted. This became a
noticeable problem for operation regions that are defined within frequently
used control methods. (Dana Meyers)
Reorganized the ACPI table header files into two main files: one for the
ACPI tables consumed by the ACPICA core, and another for the miscellaneous
ACPI tables that are consumed by the drivers and other software. The various
FADT definitions were merged into one common section and three different
tables (ACPI 1.0, 1.0+, and 2.0)
Example Code and Data Size: These are the sizes for the OS-independent
acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The
debug version of the code includes the debug output trace mechanism and has
a much larger code and data size.

Current Release:
Non-Debug Version: 81.1K Code, 17.7K Data, 98.8K Total
Debug Version: 158.9K Code, 64.9K Data, 223.8K Total
2) iASL Compiler/Disassembler and Tools:
Disassembler: Implemented support to decode and format all non-AML ACPI
tables (tables other than DSDTs and SSDTs.) This includes the new tables
added to the ACPICA headers, therefore all current and known ACPI tables are
supported.
Disassembler: The change to allow ACPI names with invalid characters also
enables the disassembly of such tables. Invalid characters within names are
changed to '*' to make the name printable; the iASL compiler will still
generate an error for such names, however, since this is an invalid ACPI
character.
Implemented an option for AcpiXtract (-a) to extract all tables found in the
input file. The default invocation extracts only the DSDTs and SSDTs.
Fixed a couple of gcc generation issues for iASL and AcpiExec and added a
makefile for the AcpiXtract utility.
----------------------------------------
17 March 2006. Summary of changes for version 20060317:
1) ACPI CA Core Subsystem:
Implemented the use of a cache object for all internal namespace nodes.
Since there are about 1000 static nodes in a typical system, this will
decrease memory use for cache implementations that minimize per-allocation
overhead (such as a slab allocator.)
Removed the reference count mechanism for internal namespace nodes, since it
was deemed unnecessary. This reduces the size of each namespace node by
about 5%-10% on all platforms. Nodes are now 20 bytes for the 32-bit case,
and 32 bytes for the 64-bit case.
Optimized several internal data structures to reduce object size on 64-bit
platforms by packing data within the 64-bit alignment. This includes the
frequently used ACPI_OPERAND_OBJECT, of which there can be ~1000 static
instances corresponding to the namespace objects.
Added two new strings for the predefined _OSI method: "Windows 2001.1 SP1"
and "Windows 2006".
Split the allocation tracking mechanism out to a separate file, from
utalloc.c to uttrack.c. This mechanism appears to be only useful for
application-level code. Kernels may wish to not include uttrack.c in
distributions.
Removed all remnants of the obsolete ACPI_REPORT_* macros and the associated
code. (These macros have been replaced by the ACPI_ERROR and ACPI_WARNING
macros.)
Code and Data Size: These are the sizes for the acpica.lib produced by the
Microsoft Visual C++ 6.0 32-bit compiler. The values do not include any ACPI
driver or OSPM code. The debug version of the code includes the debug output
trace mechanism and has a much larger code and data size. Note that these
values will vary depending on the efficiency of the compiler and the
compiler options used during generation.

Non-Debug Version: 80.9K Code, 17.7K Data, 98.6K Total
Debug Version: 158.7K Code, 64.8K Data, 223.5K Total
2) iASL Compiler/Disassembler and Tools:
Implemented an ANSI C version of the acpixtract utility. This version will
automatically extract the DSDT and all SSDTs from the input acpidump text
file and dump the binary output to separate files. It can also display a
summary of the input file including the headers for each table found and
will extract any single ACPI table, with any signature. (See
source/tools/acpixtract)
----------------------------------------
10 March 2006. Summary of changes for version 20060310:
1) ACPI CA Core Subsystem:
Tagged all external interfaces to the subsystem with the new
ACPI_EXPORT_SYMBOL macro. This macro can be defined as necessary to assist
kernel integration. For Linux, the macro resolves to the EXPORT_SYMBOL
macro. The default definition is NULL.
Added the ACPI_THREAD_ID type for the return value from AcpiOsGetThreadId.
This allows the host to define this as necessary to simplify kernel
integration. The default definition is ACPI_NATIVE_UINT.
Fixed two interpreter problems related to error processing, the deletion of
objects, and placing invalid pointers onto the internal operator result
stack. BZ 6028, 6151 (Valery Podrezov)
Increased the reference count threshold where a warning is emitted for large
reference counts in order to eliminate unnecessary warnings on systems with
large namespaces (especially 64-bit.) Increased the value from 0x400 to
0x800.
Due to universal disagreement as to the meaning of the 'c' in the calloc()
function, the ACPI_MEM_CALLOCATE macro has been renamed to
ACPI_ALLOCATE_ZEROED so that the purpose of the interface is 'clear'.
ACPI_MEM_ALLOCATE and ACPI_MEM_FREE are renamed to ACPI_ALLOCATE and
ACPI_FREE.
Code and Data Size: These are the sizes for the acpica.lib produced by the
Microsoft Visual C++ 6.0 32-bit compiler. The values do not include any ACPI
driver or OSPM code. The debug version of the code includes the debug output
trace mechanism and has a much larger code and data size. Note that these
values will vary depending on the efficiency of the compiler and the
compiler options used during generation.

Non-Debug Version: 81.1K Code, 17.8K Data, 98.9K Total
Debug Version: 161.6K Code, 65.7K Data, 227.3K Total
2) iASL Compiler/Disassembler:
Disassembler: implemented support for symbolic resource descriptor
references. If a CreateXxxxField operator references a fixed offset within a
resource descriptor, a name is assigned to the descriptor and the offset is
translated to the appropriate resource tag and pathname. The addition of
this support brings the disassembled code very close to the original ASL
source code and helps eliminate run-time errors when the disassembled code
is modified (and recompiled) in such a way as to invalidate the original
fixed offsets.
Implemented support for a Descriptor Name as the last parameter to the ASL
Register() macro. This parameter was inadvertently left out of the ACPI
specification, and will be added for ACPI 3.0b.
Fixed a problem where the use of the "_OSI" string (versus the full path
"\_OSI") caused an internal compiler error. ("No back ptr to op")
Fixed a problem with the error message that occurs when an invalid string is
used for a _HID object (such as one with an embedded asterisk: "*PNP010A".)
The correct message is now displayed.
----------------------------------------
17 February 2006. Summary of changes for version 20060217:
1) ACPI CA Core Subsystem:
Implemented a change to the IndexField support to match the behavior of the
Microsoft AML interpreter. The value written to the Index register is now a
byte offset, no longer an index based upon the width of the Data register.
This should fix IndexField problems seen on some machines where the Data
register is not exactly one byte wide. The ACPI specification will be
clarified on this point.
Fixed a problem where several resource descriptor types could overrun the
internal descriptor buffer due to size miscalculation: VendorShort,
VendorLong, and Interrupt. This was noticed on IA64 machines, but could
affect all platforms.
Fixed a problem where individual resource descriptors were misaligned within
the internal buffer, causing alignment faults on IA64 platforms.
Code and Data Size: These are the sizes for the acpica.lib produced by the
Microsoft Visual C++ 6.0 32-bit compiler. The values do not include any ACPI
driver or OSPM code. The debug version of the code includes the debug output
trace mechanism and has a much larger code and data size. Note that these
values will vary depending on the efficiency of the compiler and the
compiler options used during generation.

2) iASL Compiler/Disassembler:
Implemented support for new reserved names: _WDG and _WED are Microsoft
extensions for Windows Instrumentation Management, _TDL is a new ACPI-
defined method (Throttling Depth Limit.)
Fixed a problem where a zero-length VendorShort or VendorLong resource
descriptor was incorrectly emitted as a descriptor of length one.
----------------------------------------
10 February 2006. Summary of changes for version 20060210:
1) ACPI CA Core Subsystem:
Removed a couple of extraneous ACPI_ERROR messages that appeared during
normal execution. These became apparent after the conversion from
ACPI_DEBUG_PRINT.
Fixed a problem where the CreateField operator could hang if the BitIndex or
NumBits parameter referred to a named object. (Valery Podrezov, BZ 5359)
Fixed a problem where a DeRefOf operation on a buffer object incorrectly
failed with an exception. This also fixes a couple of related RefOf and
DeRefOf issues. (Valery Podrezov, BZ 5360/5392/5387)
Fixed a problem where the AE_BUFFER_LIMIT exception was returned instead of
AE_STRING_LIMIT on an out-of-bounds Index() operation. (Valery Podrezov, BZ
5480)
Implemented a memory cleanup at the end of the execution of each iteration
of an AML While() loop, preventing the accumulation of outstanding objects.
(Valery Podrezov, BZ 5427)
Eliminated a chunk of duplicate code in the object resolution code. (Valery
Podrezov, BZ 5336)
Fixed several warnings during the 64-bit code generation.
The AcpiSrc source code conversion tool now inserts one line of whitespace
after an if() statement that is followed immediately by a comment, improving
readability of the Linux code.
Code and Data Size: The current and previous library sizes for the core
subsystem are shown below. These are the code and data sizes for the
acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. These
values do not include any ACPI driver or OSPM code. The debug version of the
code includes the debug output trace mechanism and has a much larger code
and data size. Note that these values will vary depending on the efficiency

2) iASL Compiler/Disassembler:
Fixed a problem with the disassembly of a BankField operator with a complex
expression for the BankValue parameter.
----------------------------------------
27 January 2006. Summary of changes for version 20060127:
1) ACPI CA Core Subsystem:
Implemented support in the Resource Manager to allow unresolved namestring
references within resource package objects for the _PRT method. This support
is in addition to the previously implemented unresolved reference support
within the AML parser. If the interpreter slack mode is enabled, these
unresolved references will be passed through to the caller as a NULL package
entry.
Implemented and deployed new macros and functions for error and warning
messages across the subsystem. These macros are simpler and generate less
code than their predecessors. The new macros ACPI_ERROR, ACPI_EXCEPTION,
ACPI_WARNING, and ACPI_INFO replace the ACPI_REPORT_* macros. The older
macros remain defined to allow ACPI drivers time to migrate to the new
macros.
Implemented the ACPI_CPU_FLAGS type to simplify host OS integration of the
Acquire/Release Lock OSL interfaces.
Fixed a problem where Alias ASL operators are sometimes not correctly
resolved, in both the interpreter and the iASL compiler.
Fixed several problems with the implementation of the ConcatenateResTemplate
ASL operator. As per the ACPI specification, zero length buffers are now
treated as a single EndTag. One-length buffers always cause a fatal
exception. Non-zero length buffers that do not end with a full 2-byte EndTag
cause a fatal exception.
Fixed a possible structure overwrite in the AcpiGetObjectInfo external

Code and Data Size: The current and previous library sizes for the core
subsystem are shown below. These are the code and data sizes for the
acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. These
values do not include any ACPI driver or OSPM code. The debug version of the
code includes the debug output trace mechanism and has a much larger code
and data size. Note that these values will vary depending on the efficiency
of the compiler and the compiler options used during generation.

Alias objects.
----------------------------------------
13 January 2006. Summary of changes for version 20060113:
1) ACPI CA Core Subsystem:
Added 2006 copyright to all module headers and signons. This affects
virtually every file in the ACPICA core subsystem, iASL compiler, and the
utilities.
Enhanced the ACPICA error reporting in order to simplify user migration to
the non-debug version of ACPICA. Replaced all instances of the
ACPI_DEBUG_PRINT macro invoked at the ACPI_DB_ERROR and ACPI_DB_WARN debug
levels with the ACPI_REPORT_ERROR and ACPI_REPORT_WARNING macros,
respectively. This preserves all error and warning messages in the non-debug
version of the ACPICA code (this has been referred to as the "debug lite"
option.) Over 200 cases were converted to create a total of over 380
error/warning messages across the ACPICA code. This increases the code and
data size of the default non-debug version of the code somewhat (about 13K),
but all error/warning reporting may be disabled if desired (and code
eliminated) by specifying the ACPI_NO_ERROR_MESSAGES compile-time
configuration option. The size of the debug version of ACPICA remains about
the same.
Fixed a memory leak within the AML Debugger "Set" command. One object was
not properly deleted for every successful invocation of the command.
Code and Data Size: The current and previous library sizes for the core
subsystem are shown below. These are the code and data sizes for the
acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. These
values do not include any ACPI driver or OSPM code. The debug version of the

and data size. Note that these values will vary depending on the efficiency

2) iASL Compiler/Disassembler:
The compiler now officially supports the ACPI 3.0a specification that was
released on December 30, 2005. (Specification is available at www.acpi.info)
----------------------------------------
16 December 2005. Summary of changes for version 20051216:
1) ACPI CA Core Subsystem:
Implemented optional support to allow unresolved names within ASL Package
objects. A null object is inserted in the package when a named reference
cannot be located in the current namespace. Enabled via the interpreter
slack flag, this should eliminate AE_NOT_FOUND exceptions seen on machines
that contain such code.
Implemented an optimization to the initialization sequence that can improve
boot time. During ACPI device initialization, the _STA method is now run if
and only if the _INI method exists. The _STA method is used to determine if
the device is present; An _INI can only be run if _STA returns present, but
it is a waste of time to run the _STA method if the _INI does not exist.
(Prototype and assistance from Dong Wei)
Implemented use of the C99 uintptr_t for the pointer casting macros if it is
available in the current compiler. Otherwise, the default (void *) cast is
used as before.
Fixed some possible memory leaks found within the execution path of the
Break, Continue, If, and CreateField operators. (Valery Podrezov)
Fixed a problem introduced in the 20051202 release where an exception is
generated during method execution if a control method attempts to declare
another method.
Moved resource descriptor string constants that are used by both the AML
disassembler and AML debugger to the common utilities directory so that
these components are independent.
Implemented support in the AcpiExec utility (-e switch) to globally ignore
exceptions during control method execution (method is not aborted.)
Added the rsinfo.c source file to the AcpiExec makefile for Linux/Unix
generation.
Code and Data Size: The current and previous library sizes for the core
subsystem are shown below. These are the code and data sizes for the
acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. These
values do not include any ACPI driver or OSPM code. The debug version of the

and data size. Note that these values will vary depending on the efficiency

Non-Debug Version: 76.6K Code, 12.3K Data, 88.9K Total
Debug Version: 163.7K Code, 67.5K Data, 231.2K Total
2) iASL Compiler/Disassembler:
Fixed a problem where a CPU stack overflow fault could occur if a recursive
method call was made from within a Return statement.
----------------------------------------
02 December 2005. Summary of changes for version 20051202:
1) ACPI CA Core Subsystem:
Modified the parsing of control methods to no longer create namespace
objects during the first pass of the parse. Objects are now created only
during the execute phase, at the moment the namespace creation operator is
encountered in the AML (Name, OperationRegion, CreateByteField, etc.) This
should eliminate ALREADY_EXISTS exceptions seen on some machines where
reentrant control methods are protected by an AML mutex. The mutex will now
correctly block multiple threads from attempting to create the same object
more than once.
Increased the number of available Owner Ids for namespace object tracking
from 32 to 255. This should eliminate the OWNER_ID_LIMIT exceptions seen on
some machines with a large number of ACPI tables (either static or dynamic).
Fixed a problem with the AcpiExec utility where a fault could occur when the
-b switch (batch mode) is used.
Enhanced the namespace dump routine to output the owner ID for each
namespace object.
Code and Data Size: The current and previous library sizes for the core
subsystem are shown below. These are the code and data sizes for the
acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. These
values do not include any ACPI driver or OSPM code. The debug version of the
code includes the debug output trace mechanism and has a much larger code
and data size. Note that these values will vary depending on the efficiency
of the compiler and the compiler options used during generation.

Current Release:
Non-Debug Version: 76.3K Code, 12.3K Data, 88.6K Total
Debug Version: 163.2K Code, 67.4K Data, 230.6K Total
2) iASL Compiler/Disassembler:
Fixed a parse error during compilation of certain Switch/Case constructs. To
simplify the parse, the grammar now allows for multiple Default statements
and this error is now detected and flagged during the analysis phase.
Disassembler: The disassembly now includes the contents of the original
table header within a comment at the start of the file. This includes the
name and version of the original ASL compiler.
----------------------------------------
17 November 2005. Summary of changes for version 20051117:
1) ACPI CA Core Subsystem:
Fixed a problem in the AML parser where the method thread count could be
decremented below zero if any errors occurred during the method parse phase.
This should eliminate AE_AML_METHOD_LIMIT exceptions seen on some machines.
This also fixed a related regression with the mechanism that detects and
corrects methods that cannot properly handle reentrancy (related to the
deployment of the new OwnerId mechanism.)
Eliminated the pre-parsing of control methods (to detect errors) during
table load. Related to the problem above, this was causing unwind issues if
any errors occurred during the parse, and it seemed to be overkill. A table
load should not be aborted if there are problems with any single control
method, thus rendering this feature rather pointless.
Fixed a problem with the new table-driven resource manager where an internal
buffer overflow could occur for small resource templates.
Implemented a new external interface, AcpiGetVendorResource. This interface
will find and return a vendor-defined resource descriptor within a _CRS or
_PRS method via an ACPI 3.0 UUID match. With assistance from Bjorn Helgaas.
Removed the length limit (200) on string objects as per the upcoming ACPI
3.0A specification. This affects the following areas of the interpreter: 1)
any implicit conversion of a Buffer to a String, 2) a String object result
of the ASL Concatentate operator, 3) the String object result of the ASL
ToString operator.
Fixed a problem in the Windows OS interface layer (OSL) where a WAIT_FOREVER
on a semaphore object would incorrectly timeout. This allows the
multithreading features of the AcpiExec utility to work properly under
Windows.
Updated the Linux makefiles for the iASL compiler and AcpiExec to include
the recently added file named "utresrc.c".
Code and Data Size: The current and previous library sizes for the core
subsystem are shown below. These are the code and data sizes for the
acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. These
values do not include any ACPI driver or OSPM code. The debug version of the
code includes the debug output trace mechanism and has a much larger code
and data size. Note that these values will vary depending on the efficiency
of the compiler and the compiler options used during generation.

Current Release:
Non-Debug Version: 76.3K Code, 12.3K Data, 88.6K Total
Debug Version: 163.0K Code, 67.4K Data, 230.4K Total
2) iASL Compiler/Disassembler:
Removed the limit (200) on string objects as per the upcoming ACPI 3.0A
specification. For the iASL compiler, this means that string literals within
the source ASL can be of any length.
Enhanced the listing output to dump the AML code for resource descriptors
immediately after the ASL code for each descriptor, instead of in a block at
the end of the entire resource template.
Enhanced the compiler debug output to dump the entire original parse tree
constructed during the parse phase, before any transforms are applied to the
tree. The transformed tree is dumped also.
----------------------------------------
02 November 2005. Summary of changes for version 20051102:
1) ACPI CA Core Subsystem:
Modified the subsystem initialization sequence to improve GPE support. The
GPE initialization has been split into two parts in order to defer execution
of the _PRW methods (Power Resources for Wake) until after the hardware is
fully initialized and the SCI handler is installed. This allows the _PRW
methods to access fields protected by the Global Lock. This will fix systems
where a NO_GLOBAL_LOCK exception has been seen during initialization.
Converted the ACPI internal object disassemble and display code within the
AML debugger to fully table-driven operation, reducing code size and
increasing maintainability.
Fixed a regression with the ConcatenateResTemplate() ASL operator introduced
in the 20051021 release.
Implemented support for "local" internal ACPI object types within the
debugger "Object" command and the AcpiWalkNamespace external interfaces.
These local types include RegionFields, BankFields, IndexFields, Alias, and
reference objects.
Moved common AML resource handling code into a new file, "utresrc.c". This
code is shared by both the Resource Manager and the AML Debugger.
Code and Data Size: The current and previous library sizes for the core
subsystem are shown below. These are the code and data sizes for the
acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. These
values do not include any ACPI driver or OSPM code. The debug version of the
code includes the debug output trace mechanism and has a much larger code
and data size. Note that these values will vary depending on the efficiency
of the compiler and the compiler options used during generation.

Debug Version: 163.5K Code, 67.0K Data, 230.5K Total
Current Release:
Non-Debug Version: 76.2K Code, 12.3K Data, 88.5K Total
Debug Version: 163.0K Code, 67.4K Data, 230.4K Total
2) iASL Compiler/Disassembler:
Fixed a problem with very large initializer lists (more than 4000 elements)
for both Buffer and Package objects where the parse stack could overflow.
Enhanced the pre-compile source code scan for non-ASCII characters to ignore
characters within comment fields. The scan is now always performed and is no
longer optional, detecting invalid characters within a source file
immediately rather than during the parse phase or later.
Enhanced the ASL grammar definition to force early reductions on all list-
style grammar elements so that the overall parse stack usage is greatly
reduced. This should improve performance and reduce the possibility of parse
stack overflow.
Eliminated all reduce/reduce conflicts in the iASL parser generation. Also,
with the addition of a %expected statement, the compiler generates from
source with no warnings.
Fixed a possible segment fault in the disassembler if the input filename
does not contain a "dot" extension (Thomas Renninger).
----------------------------------------
21 October 2005. Summary of changes for version 20051021:
1) ACPI CA Core Subsystem:
Implemented support for the EM64T and other x86-64 processors. This
essentially entails recognizing that these processors support non-aligned
memory transfers. Previously, all 64-bit processors were assumed to lack
hardware support for non-aligned transfers.
Completed conversion of the Resource Manager to nearly full table-driven
operation. Specifically, the resource conversion code (convert AML to
internal format and the reverse) and the debug code to dump internal
resource descriptors are fully table-driven, reducing code and data size and
improving maintainability.
The OSL interfaces for Acquire and Release Lock now use a 64-bit flag word
on 64-bit processors instead of a fixed 32-bit word. (With assistance from
Alexey Starikovskiy)
Implemented support within the resource conversion code for the Type-
Specific byte within the various ACPI 3.0 *WordSpace macros.
Fixed some issues within the resource conversion code for the type-specific
flags for both Memory and I/O address resource descriptors. For Memory,
implemented support for the MTP and TTP flags. For I/O, split the TRS and
TTP flags into two separate fields.
Code and Data Size: The current and previous library sizes for the core
subsystem are shown below. These are the code and data sizes for the
acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. These
values do not include any ACPI driver or OSPM code. The debug version of the
code includes the debug output trace mechanism and has a much larger code
and data size. Note that these values will vary depending on the efficiency
of the compiler and the compiler options used during generation.

Debug Version: 168.0K Code, 68.3K Data, 236.3K Total
Current Release:
Non-Debug Version: 76.1K Code, 12.2K Data, 88.3K Total
Debug Version: 163.5K Code, 67.0K Data, 230.5K Total
2) iASL Compiler/Disassembler:
Relaxed a compiler restriction that disallowed a ResourceIndex byte if the
corresponding ResourceSource string was not also present in a resource
descriptor declaration. This restriction caused problems with existing
AML/ASL code that includes the Index byte without the string. When such AML
was disassembled, it could not be compiled without modification. Further,
the modified code created a resource template with a different size than the
original, breaking code that used fixed offsets into the resource template
buffer.
Removed a recent feature of the disassembler to ignore a lone ResourceIndex
byte. This byte is now emitted if present so that the exact AML can be
reproduced when the disassembled code is recompiled.
Improved comments and text alignment for the resource descriptor code
emitted by the disassembler.
Implemented disassembler support for the ACPI 3.0 AccessSize field within a
Register() resource descriptor.
----------------------------------------
30 September 2005. Summary of changes for version 20050930:
1) ACPI CA Core Subsystem:
Completed a major overhaul of the Resource Manager code - specifically,
optimizations in the area of the AML/internal resource conversion code. The
code has been optimized to simplify and eliminate duplicated code, CPU stack
use has been decreased by optimizing function parameters and local
variables, and naming conventions across the manager have been standardized
for clarity and ease of maintenance (this includes function, parameter,
variable, and struct/typedef names.) The update may force changes in some
driver code, depending on how resources are handled by the host OS.
All Resource Manager dispatch and information tables have been moved to a
single location for clarity and ease of maintenance. One new file was
created, named "rsinfo.c".
The ACPI return macros (return_ACPI_STATUS, etc.) have been modified to
guarantee that the argument is not evaluated twice, making them less prone
to macro side-effects. However, since there exists the possibility of
additional stack use if a particular compiler cannot optimize them (such as
in the debug generation case), the original macros are optionally available.
Note that some invocations of the return_VALUE macro may now cause size
mismatch warnings; the return_UINT8 and return_UINT32 macros are provided to
eliminate these. (From Randy Dunlap)
Implemented a new mechanism to enable debug tracing for individual control
methods. A new external interface, AcpiDebugTrace, is provided to enable
this mechanism. The intent is to allow the host OS to easily enable and
disable tracing for problematic control methods. This interface can be
easily exposed to a user or debugger interface if desired. See the file
psxface.c for details.
AcpiUtCallocate will now return a valid pointer if a length of zero is
specified - a length of one is used and a warning is issued. This matches
the behavior of AcpiUtAllocate.
Code and Data Size: The current and previous library sizes for the core
subsystem are shown below. These are the code and data sizes for the
acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. These
values do not include any ACPI driver or OSPM code. The debug version of the
code includes the debug output trace mechanism and has a much larger code
and data size. Note that these values will vary depending on the efficiency
of the compiler and the compiler options used during generation.

Debug Version: 168.0K Code, 68.3K Data, 236.3K Total
2) iASL Compiler/Disassembler:
A remark is issued if the effective compile-time length of a package or
buffer is zero. Previously, this was a warning.
----------------------------------------
16 September 2005. Summary of changes for version 20050916:
1) ACPI CA Core Subsystem:
Fixed a problem within the Resource Manager where support for the Generic
Register descriptor was not fully implemented. This descriptor is now fully
recognized, parsed, disassembled, and displayed.
Completely restructured the Resource Manager code to utilize table-driven
dispatch and lookup, eliminating many of the large switch() statements. This
reduces overall subsystem code size and code complexity. Affects the
resource parsing and construction, disassembly, and debug dump output.
Cleaned up and restructured the debug dump output for all resource
descriptors. Improved readability of the output and reduced code size.
Fixed a problem where changes to internal data structures caused the
optional ACPI_MUTEX_DEBUG code to fail compilation if specified.
Code and Data Size: The current and previous library sizes for the core
subsystem are shown below. These are the code and data sizes for the
acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. These
values do not include any ACPI driver or OSPM code. The debug version of the
code includes the debug output trace mechanism and has a much larger code
and data size. Note that these values will vary depending on the efficiency
of the compiler and the compiler options used during generation.

Current Release:
Non-Debug Version: 77.5K Code, 12.0K Data, 89.5K Total
Debug Version: 168.1K Code, 68.4K Data, 236.5K Total
2) iASL Compiler/Disassembler:
Updated the disassembler to automatically insert an EndDependentFn() macro
into the ASL stream if this macro is missing in the original AML code,
simplifying compilation of the resulting ASL module.
Fixed a problem in the disassembler where a disassembled ResourceSource
string (within a large resource descriptor) was not surrounded by quotes and
not followed by a comma, causing errors when the resulting ASL module was
compiled. Also, escape sequences within a ResourceSource string are now
handled correctly (especially "\\")
----------------------------------------
02 September 2005. Summary of changes for version 20050902:
1) ACPI CA Core Subsystem:
Fixed a problem with the internal Owner ID allocation and deallocation
mechanisms for control method execution and recursive method invocation.
This should eliminate the OWNER_ID_LIMIT exceptions and "Invalid OwnerId"
messages seen on some systems. Recursive method invocation depth is
currently limited to 255. (Alexey Starikovskiy)
Completely eliminated all vestiges of support for the "module-level
executable code" until this support is fully implemented and debugged. This
should eliminate the NO_RETURN_VALUE exceptions seen during table load on
some systems that invoke this support.
Fixed a problem within the resource manager code where the transaction flags
for a 64-bit address descriptor were handled incorrectly in the type-
specific flag byte.
Consolidated duplicate code within the address descriptor resource manager
code, reducing overall subsystem code size.
Fixed a fault when using the AML debugger "disassemble" command to
disassemble individual control methods.
Removed references to the "release_current" directory within the Unix
release package.
Code and Data Size: The current and previous core subsystem library sizes
are shown below. These are the code and data sizes for the acpica.lib
produced by the Microsoft Visual C++ 6.0 compiler. These values do not
include any ACPI driver or OSPM code. The debug version of the code includes
the debug output trace mechanism and has a much larger code and data size.
Note that these values will vary depending on the efficiency of the compiler
and the compiler options used during generation.

Current Release:
Non-Debug Version: 78.4K Code, 11.8K Data, 90.2K Total
Debug Version: 169.6K Code, 69.9K Data, 239.5K Total
2) iASL Compiler/Disassembler:
Implemented an error check for illegal duplicate values in the interrupt and
dma lists for the following ASL macros: Dma(), Irq(), IrqNoFlags(), and
Interrupt().
Implemented error checking for the Irq() and IrqNoFlags() macros to detect
too many values in the interrupt list (16 max) and invalid values in the
list (range 0 - 15)
The maximum length string literal within an ASL file is now restricted to
200 characters as per the ACPI specification.
Fixed a fault when using the -ln option (generate namespace listing).
Implemented an error check to determine if a DescriptorName within a
resource descriptor has already been used within the current scope.
----------------------------------------
15 August 2005. Summary of changes for version 20050815:
1) ACPI CA Core Subsystem:
Implemented a full bytewise compare to determine if a table load request is
attempting to load a duplicate table. The compare is performed if the table
signatures and table lengths match. This will allow different tables with
the same OEM Table ID and revision to be loaded - probably against the ACPI
specification, but discovered in the field nonetheless.
Added the changes.txt logfile to each of the zipped release packages.
Code and Data Size: Current and previous core subsystem library sizes are
shown below. These are the code and data sizes for the acpica.lib produced
by the Microsoft Visual C++ 6.0 compiler, and these values do not include
any ACPI driver or OSPM code. The debug version of the code includes the
debug output trace mechanism and has a much larger code and data size. Note
that these values will vary depending on the efficiency of the compiler and
the compiler options used during generation.

Non-Debug Version: 78.6K Code, 11.7K Data, 90.3K Total
Debug Version: 170.0K Code, 69.9K Data, 239.9K Total
2) iASL Compiler/Disassembler:
Fixed a problem where incorrect AML code could be generated for Package
objects if optimization is disabled (via the -oa switch).
Fixed a problem with where incorrect AML code is generated for variable-
length packages when the package length is not specified and the number of
initializer values is greater than 255.
----------------------------------------
29 July 2005. Summary of changes for version 20050729:
1) ACPI CA Core Subsystem:
Implemented support to ignore an attempt to install/load a particular ACPI
table more than once. Apparently there exists BIOS code that repeatedly
attempts to load the same SSDT upon certain events. With assistance from
Venkatesh Pallipadi.
Restructured the main interface to the AML parser in order to correctly
handle all exceptional conditions. This will prevent leakage of the OwnerId
resource and should eliminate the AE_OWNER_ID_LIMIT exceptions seen on some
machines. With assistance from Alexey Starikovskiy.
Support for "module level code" has been disabled in this version due to a
number of issues that have appeared on various machines. The support can be
enabled by defining ACPI_ENABLE_MODULE_LEVEL_CODE during subsystem
compilation. When the issues are fully resolved, the code will be enabled by
default again.
Modified the internal functions for debug print support to define the
FunctionName parameter as a (const char *) for compatibility with compiler
built-in macros such as __FUNCTION__, etc.
Linted the entire ACPICA source tree for both 32-bit and 64-bit.
Implemented support to display an object count summary for the AML Debugger
commands Object and Methods.
Code and Data Size: Current and previous core subsystem library sizes are
shown below. These are the code and data sizes for the acpica.lib produced
by the Microsoft Visual C++ 6.0 compiler, and these values do not include
any ACPI driver or OSPM code. The debug version of the code includes the
debug output trace mechanism and has a much larger code and data size. Note
that these values will vary depending on the efficiency of the compiler and
the compiler options used during generation.

2) iASL Compiler/Disassembler:
Fixed a regression that appeared in the 20050708 version of the compiler
where an error message was inadvertently emitted for invocations of the _OSI
reserved control method.
----------------------------------------
08 July 2005. Summary of changes for version 20050708:
1) ACPI CA Core Subsystem:
The use of the CPU stack in the debug version of the subsystem has been
considerably reduced. Previously, a debug structure was declared in every
function that used the debug macros. This structure has been removed in
favor of declaring the individual elements as parameters to the debug
functions. This reduces the cumulative stack use during nested execution of
ACPI function calls at the cost of a small increase in the code size of the
debug version of the subsystem. With assistance from Alexey Starikovskiy and
Len Brown.
Added the ACPI_GET_FUNCTION_NAME macro to enable the compiler-dependent
headers to define a macro that will return the current function name at
runtime (such as __FUNCTION__ or _func_, etc.) The function name is used by
the debug trace output. If ACPI_GET_FUNCTION_NAME is not defined in the
compiler-dependent header, the function name is saved on the CPU stack (one
pointer per function.) This mechanism is used because apparently there
exists no standard ANSI-C defined macro that that returns the function name.
Redesigned and reimplemented the "Owner ID" mechanism used to track
namespace objects created/deleted by ACPI tables and control method
execution. A bitmap is now used to allocate and free the IDs, thus solving
the wraparound problem present in the previous implementation. The size of
the namespace node descriptor was reduced by 2 bytes as a result (Alexey
Starikovskiy).
Removed the UINT32_BIT and UINT16_BIT types that were used for the bitfield
flag definitions within the headers for the predefined ACPI tables. These
have been replaced by UINT8_BIT in order to increase the code portability of
the subsystem. If the use of UINT8 remains a problem, we may be forced to
eliminate bitfields entirely because of a lack of portability.
Enhanced the performance of the AcpiUtUpdateObjectReference procedure. This
is a frequently used function and this improvement increases the performance
of the entire subsystem (Alexey Starikovskiy).
Fixed several possible memory leaks and the inverse - premature object
deletion (Alexey Starikovskiy).
Code and Data Size: Current and previous core subsystem library sizes are
shown below. These are the code and data sizes for the acpica.lib produced
by the Microsoft Visual C++ 6.0 compiler, and these values do not include
any ACPI driver or OSPM code. The debug version of the code includes the
debug output trace mechanism and has a much larger code and data size. Note
that these values will vary depending on the efficiency of the compiler and
the compiler options used during generation.

----------------------------------------
24 June 2005. Summary of changes for version 20050624:
1) ACPI CA Core Subsystem:
Modified the new OSL cache interfaces to use ACPI_CACHE_T as the type for
the host-defined cache object. This allows the OSL implementation to define
and type this object in any manner desired, simplifying the OSL
implementation. For example, ACPI_CACHE_T is defined as kmem_cache_t for
Linux, and should be defined in the OS-specific header file for other
operating systems as required.
Changed the interface to AcpiOsAcquireObject to directly return the
requested object as the function return (instead of ACPI_STATUS.) This
change was made for performance reasons, since this is the purpose of the
interface in the first place. AcpiOsAcquireObject is now similar to the
AcpiOsAllocate interface.
Implemented a new AML debugger command named Businfo. This command displays
information about all devices that have an associate _PRT object. The _ADR,
_HID, _UID, and _CID are displayed for these devices.
Modified the initialization sequence in AcpiInitializeSubsystem to call the
OSL interface AcpiOslInitialize first, before any local initialization. This
change was required because the global initialization now calls OSL
interfaces.
Enhanced the Dump command to display the entire contents of Package objects
(including all sub-objects and their values.)
Restructured the code base to split some files because of size and/or
because the code logically belonged in a separate file. New files are listed
below. All makefiles and project files included in the ACPI CA release have
been updated.
utilities/utcache.c /* Local cache interfaces */
utilities/utmutex.c /* Local mutex support */
utilities/utstate.c /* State object support */
interpreter/parser/psloop.c /* Main AML parse loop */
Code and Data Size: Current and previous core subsystem library sizes are
shown below. These are the code and data sizes for the acpica.lib produced
by the Microsoft Visual C++ 6.0 compiler, and these values do not include
any ACPI driver or OSPM code. The debug version of the code includes the
debug output trace mechanism and has a much larger code and data size. Note
that these values will vary depending on the efficiency of the compiler and
the compiler options used during generation.

Current Release:
Non-Debug Version: 78.6K Code, 11.5K Data, 90.1K Total
Debug Version: 165.2K Code, 69.6K Data, 234.8K Total
2) iASL Compiler/Disassembler:
Fixed a regression introduced in version 20050513 where the use of a Package
object within a Case() statement caused a compile time exception. The
original behavior has been restored (a Match() operator is emitted.)
----------------------------------------
17 June 2005. Summary of changes for version 20050617:
1) ACPI CA Core Subsystem:
Moved the object cache operations into the OS interface layer (OSL) to allow
the host OS to handle these operations if desired (for example, the Linux
OSL will invoke the slab allocator). This support is optional; the compile
time define ACPI_USE_LOCAL_CACHE may be used to utilize the original cache
code in the ACPI CA core. The new OSL interfaces are shown below. See
utalloc.c for an example implementation, and acpiosxf.h for the exact
interface definitions. With assistance from Alexey Starikovskiy.
AcpiOsCreateCache
AcpiOsDeleteCache
AcpiOsPurgeCache
AcpiOsAcquireObject
AcpiOsReleaseObject
Modified the interfaces to AcpiOsAcquireLock and AcpiOsReleaseLock to return
and restore a flags parameter. This fits better with many OS lock models.
Note: the current execution state (interrupt handler or not) is no longer
passed to these interfaces. If necessary, the OSL must determine this state
by itself, a simple and fast operation. With assistance from Alexey
Starikovskiy.
Fixed a problem in the ACPI table handling where a valid XSDT was assumed
present if the revision of the RSDP was 2 or greater. According to the ACPI
specification, the XSDT is optional in all cases, and the table manager
therefore now checks for both an RSDP >=2 and a valid XSDT pointer.
Otherwise, the RSDT pointer is used. Some ACPI 2.0 compliant BIOSs contain
only the RSDT.
Fixed an interpreter problem with the Mid() operator in the case of an input
string where the resulting output string is of zero length. It now correctly
returns a valid, null terminated string object instead of a string object
with a null pointer.
Fixed a problem with the control method argument handling to allow a store
to an Arg object that already contains an object of type Device. The Device
object is now correctly overwritten. Previously, an error was returned.
Enhanced the debugger Find command to emit object values in addition to the
found object pathnames. The output format is the same as the dump namespace
command.
Enhanced the debugger Set command. It now has the ability to set the value
of any Named integer object in the namespace (Previously, only method locals
and args could be set.)
Code and Data Size: Current and previous core subsystem library sizes are
shown below. These are the code and data sizes for the acpica.lib produced
by the Microsoft Visual C++ 6.0 compiler, and these values do not include
any ACPI driver or OSPM code. The debug version of the code includes the
debug output trace mechanism and has a much larger code and data size. Note
that these values will vary depending on the efficiency of the compiler and
the compiler options used during generation.
Previous Release:

Debug Version: 164.0K Code, 69.3K Data, 233.3K Total
Current Release:
Non-Debug Version: 78.3K Code, 11.6K Data, 89.9K Total
Debug Version: 164.0K Code, 69.1K Data, 233.1K Total
2) iASL Compiler/Disassembler:
Fixed a regression in the disassembler where if/else/while constructs were
output incorrectly. This problem was introduced in the previous release
(20050526). This problem also affected the single-step disassembly in the
debugger.
Fixed a problem where compiling the reserved _OSI method would randomly (but
rarely) produce compile errors.
Enhanced the disassembler to emit compilable code in the face of incorrect
AML resource descriptors. If the optional ResourceSourceIndex is present,
but the ResourceSource is not, do not emit the ResourceSourceIndex in the
disassembly. Otherwise, the resulting code cannot be compiled without
errors.
----------------------------------------
26 May 2005. Summary of changes for version 20050526:
1) ACPI CA Core Subsystem:
Implemented support to execute Type 1 and Type 2 AML opcodes appearing at
the module level (not within a control method.) These opcodes are executed
exactly once at the time the table is loaded. This type of code was legal up
until the release of ACPI 2.0B (2002) and is now supported within ACPI CA in
order to provide backwards compatibility with earlier BIOS implementations.
This eliminates the "Encountered executable code at module level" warning
that was previously generated upon detection of such code.
Fixed a problem in the interpreter where an AE_NOT_FOUND exception could
inadvertently be generated during the lookup of namespace objects in the
second pass parse of ACPI tables and control methods. It appears that this
problem could occur during the resolution of forward references to namespace
objects.
Added the ACPI_MUTEX_DEBUG #ifdef to the AcpiUtReleaseMutex function,
corresponding to the same #ifdef in the AcpiUtAcquireMutex function. This
allows the deadlock detection debug code to be compiled out in the normal
case, improving mutex performance (and overall subsystem performance)
considerably.
Implemented a handful of miscellaneous fixes for possible memory leaks on
error conditions and error handling control paths. These fixes were
suggested by FreeBSD and the Coverity Prevent source code analysis tool.
Added a check for a null RSDT pointer in AcpiGetFirmwareTable (tbxfroot.c)
to prevent a fault in this error case.
Code and Data Size: Current and previous core subsystem library sizes are
shown below. These are the code and data sizes for the acpica.lib produced
by the Microsoft Visual C++ 6.0 compiler, and these values do not include
any ACPI driver or OSPM code. The debug version of the code includes the
debug output trace mechanism and has a much larger code and data size. Note
that these values will vary depending on the efficiency of the compiler and
the compiler options used during generation.

Debug Version: 163.7K Code, 69.3K Data, 233.0K Total
Current Release:
Non-Debug Version: 78.1K Code, 11.6K Data, 89.7K Total
Debug Version: 164.0K Code, 69.3K Data, 233.3K Total
2) iASL Compiler/Disassembler:
Implemented support to allow Type 1 and Type 2 ASL operators to appear at
the module level (not within a control method.) These operators will be
executed once at the time the table is loaded. This type of code was legal
up until the release of ACPI 2.0B (2002) and is now supported by the iASL
compiler in order to provide backwards compatibility with earlier BIOS ASL
code.
The ACPI integer width (specified via the table revision ID or the -r
override, 32 or 64 bits) is now used internally during compile-time constant
folding to ensure that constants are truncated to 32 bits if necessary.
Previously, the revision ID value was only emitted in the AML table header.
An error message is now generated for the Mutex and Method operators if the
SyncLevel parameter is outside the legal range of 0 through 15.
Fixed a problem with the Method operator ParameterTypes list handling (ACPI
3.0). Previously, more than 2 types or 2 arguments generated a syntax error.
The actual underlying implementation of method argument typechecking is
still under development, however.
----------------------------------------
13 May 2005. Summary of changes for version 20050513:
1) ACPI CA Core Subsystem:
Implemented support for PCI Express root bridges -- added support for device
PNP0A08 in the root bridge search within AcpiEvPciConfigRegionSetup.
The interpreter now automatically truncates incoming 64-bit constants to 32
bits if currently executing out of a 32-bit ACPI table (Revision < 2). This
also affects the iASL compiler constant folding. (Note: as per below, the
iASL compiler no longer allows 64-bit constants within 32-bit tables.)
Fixed a problem where string and buffer objects with "static" pointers
(pointers to initialization data within an ACPI table) were not handled
consistently. The internal object copy operation now always copies the data
to a newly allocated buffer, regardless of whether the source object is
static or not.
Fixed a problem with the FromBCD operator where an implicit result
conversion was improperly performed while storing the result to the target
operand. Since this is an "explicit conversion" operator, the implicit
conversion should never be performed on the output.
Fixed a problem with the CopyObject operator where a copy to an existing
named object did not always completely overwrite the existing object stored
at name. Specifically, a buffer-to-buffer copy did not delete the existing
buffer.
Replaced "InterruptLevel" with "InterruptNumber" in all GPE interfaces and
structs for consistency.
Code and Data Size: Current and previous core subsystem library sizes are
shown below. These are the code and data sizes for the acpica.lib produced
by the Microsoft Visual C++ 6.0 compiler, and these values do not include
any ACPI driver or OSPM code. The debug version of the code includes the
debug output trace mechanism and has a much larger code and data size. Note
that these values will vary depending on the efficiency of the compiler and
the compiler options used during generation.
Previous Release:
Non-Debug Version: 78.2K Code, 11.6K Data, 89.8K Total
Debug Version: 163.7K Code, 69.3K Data, 233.0K Total
Current Release: (Same sizes)
Non-Debug Version: 78.2K Code, 11.6K Data, 89.8K Total
Debug Version: 163.7K Code, 69.3K Data, 233.0K Total
2) iASL Compiler/Disassembler:
The compiler now emits a warning if an attempt is made to generate a 64-bit
integer constant from within a 32-bit ACPI table (Revision < 2). The integer
is truncated to 32 bits.
Fixed a problem with large package objects: if the static length of the
package is greater than 255, the "variable length package" opcode is
emitted. Previously, this caused an error. This requires an update to the
ACPI spec, since it currently (incorrectly) states that packages larger than
255 elements are not allowed.
The disassembler now correctly handles variable length packages and packages
larger than 255 elements.
----------------------------------------
08 April 2005. Summary of changes for version 20050408:
1) ACPI CA Core Subsystem:
Fixed three cases in the interpreter where an "index" argument to an ASL
function was still (internally) 32 bits instead of the required 64 bits.
This was the Index argument to the Index, Mid, and Match operators.
The "strupr" function is now permanently local (AcpiUtStrupr), since this is
not a POSIX-defined function and not present in most kernel-level C
libraries. All references to the C library strupr function have been removed
from the headers.
Completed the deployment of static functions/prototypes. All prototypes with
the static attribute have been moved from the headers to the owning C file.
Implemented an extract option (-e) for the AcpiBin utility (AML binary
utility). This option allows the utility to extract individual ACPI tables
from the output of AcpiDmp. It provides the same functionality of the
acpixtract.pl perl script without the worry of setting the correct perl
options. AcpiBin runs on Windows and has not yet been generated/validated in
the Linux/Unix environment (but should be soon).
Updated and fixed the table dump option for AcpiBin (-d). This option
converts a single ACPI table to a hex/ascii file, similar to the output of
AcpiDmp.
Code and Data Size: Current and previous core subsystem library sizes are
shown below. These are the code and data sizes for the acpica.lib produced
by the Microsoft Visual C++ 6.0 compiler, and these values do not include
any ACPI driver or OSPM code. The debug version of the code includes the
debug output trace mechanism and has a much larger code and data size. Note
that these values will vary depending on the efficiency of the compiler and
the compiler options used during generation.

Non-Debug Version: 78.2K Code, 11.6K Data, 89.8K Total
Debug Version: 163.7K Code, 69.3K Data, 233.0K Total
2) iASL Compiler/Disassembler:
Disassembler fix: Added a check to ensure that the table length found in the
ACPI table header within the input file is not longer than the actual input
file size. This indicates some kind of file or table corruption.
----------------------------------------
29 March 2005. Summary of changes for version 20050329:
1) ACPI CA Core Subsystem:
An error is now generated if an attempt is made to create a Buffer Field of
length zero (A CreateField with a length operand of zero.)
The interpreter now issues a warning whenever executable code at the module
level is detected during ACPI table load. This will give some idea of the
prevalence of this type of code.
Implemented support for references to named objects (other than control
methods) within package objects.
Enhanced package object output for the debug object. Package objects are now
completely dumped, showing all elements.
Enhanced miscellaneous object output for the debug object. Any object can
now be written to the debug object (for example, a device object can be
written, and the type of the object will be displayed.)
The "static" qualifier has been added to all local functions across both the
core subsystem and the iASL compiler.
The number of "long" lines (> 80 chars) within the source has been
significantly reduced, by about 1/3.
Cleaned up all header files to ensure that all CA/iASL functions are
prototyped (even static functions) and the formatting is consistent.
Two new header files have been added, acopcode.h and acnames.h.
Removed several obsolete functions that were no longer used.
Code and Data Size: Current and previous core subsystem library sizes are
shown below. These are the code and data sizes for the acpica.lib produced
by the Microsoft Visual C++ 6.0 compiler, and these values do not include
any ACPI driver or OSPM code. The debug version of the code includes the
debug output trace mechanism and has a much larger code and data size. Note
that these values will vary depending on the efficiency of the compiler and
the compiler options used during generation.

Current Release:
Non-Debug Version: 78.0K Code, 11.6K Data, 89.6K Total
Debug Version: 163.5K Code, 69.3K Data, 232.8K Total
2) iASL Compiler/Disassembler:
Fixed a problem with the resource descriptor generation/support. For the
ResourceSourceIndex and the ResourceSource fields, both must be present, or
both must be not present - can't have one without the other.
The compiler now returns non-zero from the main procedure if any errors have
occurred during the compilation.
----------------------------------------
09 March 2005. Summary of changes for version 20050309:
1) ACPI CA Core Subsystem:
The string-to-buffer implicit conversion code has been modified again after
a change to the ACPI specification. In order to match the behavior of the
other major ACPI implementation, the target buffer is no longer truncated if
the source string is smaller than an existing target buffer. This change
requires an update to the ACPI spec, and should eliminate the recent
AE_AML_BUFFER_LIMIT issues.
The "implicit return" support was rewritten to a new algorithm that solves
the general case. Rather than attempt to determine when a method is about to
exit, the result of every ASL operator is saved momentarily until the very
next ASL operator is executed. Therefore, no matter how the method exits,
there will always be a saved implicit return value. This feature is only
enabled with the AcpiGbl_EnableInterpreterSlack flag, and should eliminate
AE_AML_NO_RETURN_VALUE errors when enabled.
Implemented implicit conversion support for the predicate (operand) of the
If, Else, and While operators. String and Buffer arguments are automatically
converted to Integers.
Changed the string-to-integer conversion behavior to match the new ACPI
errata: "If no integer object exists, a new integer is created. The ASCII
string is interpreted as a hexadecimal constant. Each string character is
interpreted as a hexadecimal value ('0'-'9', 'A'-'F', 'a', 'f'), starting
with the first character as the most significant digit, and ending with the
first non-hexadecimal character or end-of-string." This means that the first
non-hex character terminates the conversion and this is the code that was
changed.
Fixed a problem where the ObjectType operator would fail (fault) when used
on an Index of a Package which pointed to a null package element. The
operator now properly returns zero (Uninitialized) in this case.
Fixed a problem where the While operator used excessive memory by not
properly popping the result stack during execution. There was no memory leak
after execution, however. (Code provided by Valery Podrezov.)
Fixed a problem where references to control methods within Package objects
caused the method to be invoked, instead of producing a reference object
pointing to the method.
Restructured and simplified the pswalk.c module (AcpiPsDeleteParseTree) to
improve performance and reduce code size. (Code provided by Alexey
Starikovskiy.)
Code and Data Size: Current and previous core subsystem library sizes are
shown below. These are the code and data sizes for the acpica.lib produced
by the Microsoft Visual C++ 6.0 compiler, and these values do not include
any ACPI driver or OSPM code. The debug version of the code includes the
debug output trace mechanism and has a much larger code and data size. Note
that these values will vary depending on the efficiency of the compiler and
the compiler options used during generation.

Current Release:
Non-Debug Version: 78.3K Code, 11.5K Data, 89.8K Total
Debug Version: 165.4K Code, 69.7K Data, 236.1K Total
2) iASL Compiler/Disassembler:
Fixed a problem with the Return operator with no arguments. Since the AML
grammar for the byte encoding requires an operand for the Return opcode, the
compiler now emits a Return(Zero) for this case. An ACPI specification
update has been written for this case.
For tables other than the DSDT, namepath optimization is automatically
disabled. This is because SSDTs can be loaded anywhere in the namespace, the
compiler has no knowledge of where, and thus cannot optimize namepaths.
Added "ProcessorObj" to the ObjectTypeKeyword list. This object type was
inadvertently omitted from the ACPI specification, and will require an
update to the spec.
The source file scan for ASCII characters is now optional (-a). This change
was made because some vendors place non-ascii characters within comments.
However, the scan is simply a brute-force byte compare to ensure all
characters in the file are in the range 0x00 to 0x7F.
Fixed a problem with the CondRefOf operator where the compiler was
inappropriately checking for the existence of the target. Since the point of
the operator is to check for the existence of the target at run-time, the
compiler no longer checks for the target existence.
Fixed a problem where errors generated from the internal AML interpreter
during constant folding were not handled properly, causing a fault.
Fixed a problem with overly aggressive range checking for the Stall
operator. The valid range (max 255) is now only checked if the operand is of
type Integer. All other operand types cannot be statically checked.
Fixed a problem where control method references within the RefOf, DeRefOf,
and ObjectType operators were not treated properly. They are now treated as
actual references, not method invocations.
Fixed and enhanced the "list namespace" option (-ln). This option was broken
a number of releases ago.
Improved error handling for the Field, IndexField, and BankField operators.
The compiler now cleanly reports and recovers from errors in the field
component (FieldUnit) list.
Fixed a disassembler problem where the optional ResourceDescriptor fields
TRS and TTP were not always handled correctly.
Disassembler - Comments in output now use "//" instead of "/*"
----------------------------------------
28 February 2005. Summary of changes for version 20050228:
1) ACPI CA Core Subsystem:
Fixed a problem where the result of an Index() operator (an object
reference) must increment the reference count on the target object for the
life of the object reference.
Implemented AML Interpreter and Debugger support for the new ACPI 3.0
Extended Address (IO, Memory, Space), QwordSpace, DwordSpace, and WordSpace
resource descriptors.
Implemented support in the _OSI method for the ACPI 3.0 "Extended Address
Space Descriptor" string, indicating interpreter support for the descriptors
above.
Implemented header support for the new ACPI 3.0 FADT flag bits.
Implemented header support for the new ACPI 3.0 PCI Express bits for the PM1
status/enable registers.
Updated header support for the MADT processor local Apic struct and MADT
platform interrupt source struct for new ACPI 3.0 fields.
Implemented header support for the SRAT and SLIT ACPI tables.
Implemented the -s switch in AcpiExec to enable the "InterpreterSlack" flag
at runtime.
Code and Data Size: Current and previous core subsystem library sizes are
shown below. These are the code and data sizes for the acpica.lib produced
by the Microsoft Visual C++ 6.0 compiler, and these values do not include
any ACPI driver or OSPM code. The debug version of the code includes the
debug output trace mechanism and has a much larger code and data size. Note
that these values will vary depending on the efficiency of the compiler and
the compiler options used during generation.

Non-Debug Version: 78.3K Code, 11.5K Data, 89.8K Total
Debug Version: 165.4K Code, 69.6K Data, 236.0K Total
2) iASL Compiler/Disassembler:
Fixed a problem with the internal 64-bit String-to-integer conversion with
strings less than two characters long.
Fixed a problem with constant folding where the result of the Index()
operator can not be considered a constant. This means that Index() cannot be
a type3 opcode and this will require an update to the ACPI specification.
Disassembler: Implemented support for the TTP, MTP, and TRS resource
descriptor fields. These fields were inadvertently ignored and not output in
the disassembly of the resource descriptor.
----------------------------------------
11 February 2005. Summary of changes for version 20050211:
1) ACPI CA Core Subsystem:
Implemented ACPI 3.0 support for implicit conversion within the Match()
operator. MatchObjects can now be of type integer, buffer, or string instead
of just type integer. Package elements are implicitly converted to the type
of the MatchObject. This change aligns the behavior of Match() with the
behavior of the other logical operators (LLess(), etc.) It also requires an
errata change to the ACPI specification as this support was intended for
ACPI 3.0, but was inadvertently omitted.
Fixed a problem with the internal implicit "to buffer" conversion. Strings
that are converted to buffers will cause buffer truncation if the string is
smaller than the target buffer. Integers that are converted to buffers will
not cause buffer truncation, only zero extension (both as per the ACPI
spec.) The problem was introduced when code was added to truncate the
buffer, but this should not be performed in all cases, only the string case.
Fixed a problem with the Buffer and Package operators where the interpreter
would get confused if two such operators were used as operands to an ASL
operator (such as LLess(Buffer(1){0},Buffer(1){1}). The internal result
stack was not being popped after the execution of these operators, resulting
in an AE_NO_RETURN_VALUE exception.
Fixed a problem with constructs of the form Store(Index(...),...). The
reference object returned from Index was inadvertently resolved to an actual
value. This problem was introduced in version 20050114 when the behavior of
Store() was modified to restrict the object types that can be used as the
source operand (to match the ACPI specification.)
Reduced excessive stack use within the AcpiGetObjectInfo procedure.
Added a fix to aclinux.h to allow generation of AcpiExec on Linux.
Updated the AcpiSrc utility to add the FADT_DESCRIPTOR_REV2_MINUS struct.
Code and Data Size: Current and previous core subsystem library sizes are
shown below. These are the code and data sizes for the acpica.lib produced
by the Microsoft Visual C++ 6.0 compiler, and these values do not include
any ACPI driver or OSPM code. The debug version of the code includes the
debug output trace mechanism and has a much larger code and data size. Note
that these values will vary depending on the efficiency of the compiler and
the compiler options used during generation.

2) iASL Compiler/Disassembler:
Fixed a code generation problem in the constant folding optimization code
where incorrect code was generated if a constant was reduced to a buffer
object (i.e., a reduced type 5 opcode.)
Fixed a typechecking problem for the ToBuffer operator. Caused by an
incorrect return type in the internal opcode information table.
----------------------------------------
25 January 2005. Summary of changes for version 20050125:
1) ACPI CA Core Subsystem:
Fixed a recently introduced problem with the Global Lock where the
underlying semaphore was not created. This problem was introduced in
version 20050114, and caused an AE_AML_NO_OPERAND exception during an
Acquire() operation on _GL.
The local object cache is now optional, and is disabled by default. Both
AcpiExec and the iASL compiler enable the cache because they run in user
mode and this enhances their performance. #define ACPI_ENABLE_OBJECT_CACHE
to enable the local cache.
Fixed an issue in the internal function AcpiUtEvaluateObject concerning the
optional "implicit return" support where an error was returned if no return
object was expected, but one was implicitly returned. AE_OK is now returned
in this case and the implicitly returned object is deleted.
AcpiUtEvaluateObject is only occasionally used, and only to execute reserved
methods such as _STA and _INI where the return type is known up front.
Fixed a few issues with the internal convert-to-integer code. It now returns
an error if an attempt is made to convert a null string, a string of only
blanks/tabs, or a zero-length buffer. This affects both implicit conversion
and explicit conversion via the ToInteger() operator.
The internal debug code in AcpiUtAcquireMutex has been commented out. It is
not needed for normal operation and should increase the performance of the
entire subsystem. The code remains in case it is needed for debug purposes
again.
The AcpiExec source and makefile are included in the Unix/Linux package for
the first time.
Code and Data Size: Current and previous core subsystem library sizes are
shown below. These are the code and data sizes for the acpica.lib produced
by the Microsoft Visual C++ 6.0 compiler, and these values do not include
any ACPI driver or OSPM code. The debug version of the code includes the
debug output trace mechanism and has a much larger code and data size. Note
that these values will vary depending on the efficiency of the compiler and
the compiler options used during generation.

2) iASL Compiler/Disassembler:
Switch/Case support: A warning is now issued if the type of the Switch value
cannot be determined at compile time. For example, Switch(Arg0) will
generate the warning, and the type is assumed to be an integer. As per the
ACPI spec, use a construct such as Switch(ToInteger(Arg0)) to eliminate the
warning.
Switch/Case support: Implemented support for buffer and string objects as
the switch value. This is an ACPI 3.0 feature, now that LEqual supports
buffers and strings.
Switch/Case support: The emitted code for the LEqual() comparisons now uses
the switch value as the first operand, not the second. The case value is now
the second operand, and this allows the case value to be implicitly
converted to the type of the switch value, not the other way around.
Switch/Case support: Temporary variables are now emitted immediately within
the control method, not at the global level. This means that there are now
36 temps available per-method, not 36 temps per-module as was the case with
the earlier implementation (_T_0 through _T_9 and _T_A through _T_Z.)
----------------------------------------
14 January 2005. Summary of changes for version 20050114:
Added 2005 copyright to all module headers. This affects every module in
the core subsystem, iASL compiler, and the utilities.
1) ACPI CA Core Subsystem:
Fixed an issue with the String-to-Buffer conversion code where the string
null terminator was not included in the buffer after conversion, but there
is existing ASL that assumes the string null terminator is included. This is
the root of the ACPI_AML_BUFFER_LIMIT regression. This problem was
introduced in the previous version when the code was updated to correctly
set the converted buffer size as per the ACPI specification. The ACPI spec
is ambiguous and will be updated to specify that the null terminator must be
included in the converted buffer. This also affects the ToBuffer() ASL
operator.
Fixed a problem with the Mid() ASL/AML operator where it did not work
correctly on Buffer objects. Newly created sub-buffers were not being marked
as initialized.
Fixed a problem in AcpiTbFindTable where incorrect string compares were
performed on the OemId and OemTableId table header fields. These fields are
not null terminated, so strncmp is now used instead of strcmp.
Implemented a restriction on the Store() ASL/AML operator to align the
behavior with the ACPI specification. Previously, any object could be used
as the source operand. Now, the only objects that may be used are Integers,
Buffers, Strings, Packages, Object References, and DDB Handles. If
necessary, the original behavior can be restored by enabling the
EnableInterpreterSlack flag.
Enhanced the optional "implicit return" support to allow an implicit return
value from methods that are invoked externally via the AcpiEvaluateObject
interface. This enables implicit returns from the _STA and _INI methods,
for example.
Changed the Revision() ASL/AML operator to return the current version of the
AML interpreter, in the YYYYMMDD format. Previously, it incorrectly returned
the supported ACPI version (This is the function of the _REV method).
Updated the _REV predefined method to return the currently supported version
of ACPI, now 3.
Implemented batch mode option for the AcpiExec utility (-b).
Code and Data Size: Current and previous core subsystem library sizes are
shown below. These are the code and data sizes for the acpica.lib produced
by the Microsoft Visual C++ 6.0 compiler, and these values do not include
any ACPI driver or OSPM code. The debug version of the code includes the
debug output trace mechanism and has a much larger code and data size. Note
that these values will vary depending on the efficiency of the compiler and
the compiler options used during generation.

----------------------------------------
10 December 2004. Summary of changes for version 20041210:
ACPI 3.0 support is nearing completion in both the iASL compiler and the
ACPI CA core subsystem.
1) ACPI CA Core Subsystem:
Fixed a problem in the ToDecimalString operator where the resulting string
length was incorrectly calculated. The length is now calculated exactly,
eliminating incorrect AE_STRING_LIMIT exceptions.
Fixed a problem in the ToHexString operator to allow a maximum 200 character
string to be produced.
Fixed a problem in the internal string-to-buffer and buffer-to-buffer copy
routine where the length of the resulting buffer was not truncated to the
new size (if the target buffer already existed).
Code and Data Size: Current and previous core subsystem library sizes are
shown below. These are the code and data sizes for the acpica.lib produced
by the Microsoft Visual C++ 6.0 compiler, and these values do not include
any ACPI driver or OSPM code. The debug version of the code includes the
debug output trace mechanism and has a much larger code and data size. Note
that these values will vary depending on the efficiency of the compiler and
the compiler options used during generation.

Current Release:
Non-Debug Version: 78.3K Code, 11.5K Data, 89.8K Total
Debug Version: 165.3K Code, 69.4K Data, 234.7K Total
2) iASL Compiler/Disassembler:
Implemented the new ACPI 3.0 resource template macros - DWordSpace,
ExtendedIO, ExtendedMemory, ExtendedSpace, QWordSpace, and WordSpace.
Includes support in the disassembler.
Implemented support for the new (ACPI 3.0) parameter to the Register macro,
AccessSize.
Fixed a problem where the _HE resource name for the Interrupt macro was
referencing bit 0 instead of bit 1.
Implemented check for maximum 255 interrupts in the Interrupt macro.
Fixed a problem with the predefined resource descriptor names where
incorrect AML code was generated if the offset within the resource buffer
was 0 or 1. The optimizer shortened the AML code to a single byte opcode
but did not update the surrounding package lengths.
Changes to the Dma macro: All channels within the channel list must be in
the range 0-7. Maximum 8 channels can be specified. BusMaster operand is
optional (default is BusMaster).
Implemented check for maximum 7 data bytes for the VendorShort macro.
The ReadWrite parameter is now optional for the Memory32 and similar macros.
----------------------------------------
03 December 2004. Summary of changes for version 20041203:
1) ACPI CA Core Subsystem:
The low-level field insertion/extraction code (exfldio) has been completely
rewritten to eliminate unnecessary complexity, bugs, and boundary
conditions.
Fixed a problem in the ToInteger, ToBuffer, ToHexString, and ToDecimalString
operators where the input operand could be inadvertently deleted if no
conversion was necessary (e.g., if the input to ToInteger was an Integer
object.)
Fixed a problem with the ToDecimalString and ToHexString where an incorrect
exception code was returned if the resulting string would be > 200 chars.
AE_STRING_LIMIT is now returned.
Fixed a problem with the Concatenate operator where AE_OK was always
returned, even if the operation failed.
Fixed a problem in oswinxf (used by AcpiExec and iASL) to allow > 128
semaphores to be allocated.
Code and Data Size: Current and previous core subsystem library sizes are
shown below. These are the code and data sizes for the acpica.lib produced
by the Microsoft Visual C++ 6.0 compiler, and these values do not include
any ACPI driver or OSPM code. The debug version of the code includes the
debug output trace mechanism and has a much larger code and data size. Note
that these values will vary depending on the efficiency of the compiler and

Current Release:
Non-Debug Version: 78.3K Code, 11.5K Data, 89.8K Total
Debug Version: 164.7K Code, 68.5K Data, 233.2K Total
2) iASL Compiler/Disassembler:
Fixed typechecking for the ObjectType and SizeOf operators. Problem was
recently introduced in 20041119.
Fixed a problem with the ToUUID macro where the upper nybble of each buffer
byte was inadvertently set to zero.
----------------------------------------
19 November 2004. Summary of changes for version 20041119:
1) ACPI CA Core Subsystem:
Fixed a problem in the internal ConvertToInteger routine where new integers
were not truncated to 32 bits for 32-bit ACPI tables. This routine converts
buffers and strings to integers.
Implemented support to store a value to an Index() on a String object. This
is an ACPI 2.0 feature that had not yet been implemented.
Implemented new behavior for storing objects to individual package elements
(via the Index() operator). The previous behavior was to invoke the implicit
conversion rules if an object was already present at the index. The new
behavior is to simply delete any existing object and directly store the new
object. Although the ACPI specification seems unclear on this subject, other
ACPI implementations behave in this manner. (This is the root of the
AE_BAD_HEX_CONSTANT issue.)
Modified the RSDP memory scan mechanism to support the extended checksum for
ACPI 2.0 (and above) RSDPs. Note that the search continues until a valid
RSDP signature is found with a valid checksum.
Code and Data Size: Current and previous core subsystem library sizes are
shown below. These are the code and data sizes for the acpica.lib produced
by the Microsoft Visual C++ 6.0 compiler, and these values do not include
any ACPI driver or OSPM code. The debug version of the code includes the
debug output trace mechanism and has a much larger code and data size. Note
that these values will vary depending on the efficiency of the compiler and
the compiler options used during generation.

2) iASL Compiler/Disassembler:
Fixed a missing semicolon in the aslcompiler.y file.
----------------------------------------
05 November 2004. Summary of changes for version 20041105:
1) ACPI CA Core Subsystem:
Implemented support for FADT revision 2. This was an interim table (between
ACPI 1.0 and ACPI 2.0) that adds support for the FADT reset register.
Implemented optional support to allow uninitialized LocalX and ArgX
variables in a control method. The variables are initialized to an Integer
object with a value of zero. This support is enabled by setting the
AcpiGbl_EnableInterpreterSlack flag to TRUE.
Implemented support for Integer objects for the SizeOf operator. Either 4
or 8 is returned, depending on the current integer size (32-bit or 64-bit,
depending on the parent table revision).
Fixed a problem in the implementation of the SizeOf and ObjectType operators
where the operand was resolved to a value too early, causing incorrect
return values for some objects.
Fixed some possible memory leaks during exceptional conditions.
Code and Data Size: Current and previous core subsystem library sizes are
shown below. These are the code and data sizes for the acpica.lib produced
by the Microsoft Visual C++ 6.0 compiler, and these values do not include
any ACPI driver or OSPM code. The debug version of the code includes the
debug output trace mechanism and has a much larger code and data size. Note
that these values will vary depending on the efficiency of the compiler and
the compiler options used during generation.

2) iASL Compiler/Disassembler:
Implemented support for all ACPI 3.0 reserved names and methods.
Implemented all ACPI 3.0 grammar elements in the front-end, including
support for semicolons.
Implemented the ACPI 3.0 Function() and ToUUID() macros
Fixed a problem in the disassembler where a Scope() operator would not be
emitted properly if the target of the scope was in another table.
----------------------------------------
15 October 2004. Summary of changes for version 20041015:
Note: ACPI CA is currently undergoing an in-depth and complete formal
evaluation to test/verify the following areas. Other suggestions are
welcome. This will result in an increase in the frequency of releases and
the number of bug fixes in the next few months.
- Functional tests for all ASL/AML operators
- All implicit/explicit type conversions
- Bit fields and operation regions
- 64-bit math support and 32-bit-only "truncated" math support
- Exceptional conditions, both compiler and interpreter
- Dynamic object deletion and memory leaks
- ACPI 3.0 support when implemented
- External interfaces to the ACPI subsystem
1) ACPI CA Core Subsystem:
Fixed two alignment issues on 64-bit platforms - within debug statements in
AcpiEvGpeDetect and AcpiEvCreateGpeBlock. Removed references to the Address
field within the non-aligned ACPI generic address structure.
Fixed a problem in the Increment and Decrement operators where incorrect
operand resolution could result in the inadvertent modification of the
original integer when the integer is passed into another method as an
argument and the arg is then incremented/decremented.
Fixed a problem in the FromBCD operator where the upper 32-bits of a 64-bit
BCD number were truncated during conversion.
Fixed a problem in the ToDecimal operator where the length of the resulting
string could be set incorrectly too long if the input operand was a Buffer
object.
Fixed a problem in the Logical operators (LLess, etc.) where a NULL byte (0)
within a buffer would prematurely terminate a compare between buffer
objects.
Added a check for string overflow (>200 characters as per the ACPI
specification) during the Concatenate operator with two string operands.
Code and Data Size: Current and previous core subsystem library sizes are
shown below. These are the code and data sizes for the acpica.lib produced
by the Microsoft Visual C++ 6.0 compiler, and these values do not include
any ACPI driver or OSPM code. The debug version of the code includes the
debug output trace mechanism and has a much larger code and data size. Note
that these values will vary depending on the efficiency of the compiler and
the compiler options used during generation.

Current Release:
Non-Debug Version: 78.0K Code, 11.5K Data, 89.5K Total
Debug Version: 164.8K Code, 68.6K Data, 233.4K Total
2) iASL Compiler/Disassembler:
Allow the use of the ObjectType operator on uninitialized Locals and Args
(returns 0 as per the ACPI specification).
Fixed a problem where the compiler would fault if there was a syntax error
in the FieldName of all of the various CreateXXXField operators.
Disallow the use of lower case letters within the EISAID macro, as per the
ACPI specification. All EISAID strings must be of the form "UUUNNNN" Where
U is an uppercase letter and N is a hex digit.
----------------------------------------
06 October 2004. Summary of changes for version 20041006:
1) ACPI CA Core Subsystem:
Implemented support for the ACPI 3.0 Timer operator. This ASL function
implements a 64-bit timer with 100 nanosecond granularity.
Defined a new OSL interface, AcpiOsGetTimer. This interface is used to
implement the ACPI 3.0 Timer operator. This allows the host OS to implement
the timer with the best clock available. Also, it keeps the core subsystem
out of the clock handling business, since the host OS (usually) performs
this function.
Fixed an alignment issue on 64-bit platforms. The HwLowLevelRead(Write)
functions use a 64-bit address which is part of the packed ACPI Generic
Address Structure. Since the structure is non-aligned, the alignment macros
are now used to extract the address to a local variable before use.
Fixed a problem where the ToInteger operator assumed all input strings were
hexadecimal. The operator now handles both decimal strings and hex strings
(prefixed with "0x").
Fixed a problem where the string length in the string object created as a
result of the internal ConvertToString procedure could be incorrect. This
potentially affected all implicit conversions and also the ToDecimalString
and ToHexString operators.
Fixed two problems in the ToString operator. If the length parameter was
zero, an incorrect string object was created and the value of the input
length parameter was inadvertently changed from zero to Ones.
Fixed a problem where the optional ResourceSource string in the ExtendedIRQ
resource macro was ignored.
Simplified the interfaces to the internal division functions, reducing code
size and complexity.
Code and Data Size: Current and previous core subsystem library sizes are
shown below. These are the code and data sizes for the acpica.lib produced
by the Microsoft Visual C++ 6.0 compiler, and these values do not include
any ACPI driver or OSPM code. The debug version of the code includes the
debug output trace mechanism and has a much larger code and data size. Note
that these values will vary depending on the efficiency of the compiler and
the compiler options used during generation.

Debug Version: 164.6K Code, 68.5K Data, 233.1K Total
2) iASL Compiler/Disassembler:
Implemented support for the ACPI 3.0 Timer operator.
Fixed a problem where the Default() operator was inadvertently ignored in a
Switch/Case block. This was a problem in the translation of the Switch
statement to If...Else pairs.
Added support to allow a standalone Return operator, with no parentheses (or
operands).
Fixed a problem with code generation for the ElseIf operator where the
translated Else...If parse tree was improperly constructed leading to the
loss of some code.
----------------------------------------
22 September 2004. Summary of changes for version 20040922:
1) ACPI CA Core Subsystem:
Fixed a problem with the implementation of the LNot() operator where "Ones"
was not returned for the TRUE case. Changed the code to return Ones instead
of (!Arg) which was usually 1. This change affects iASL constant folding for
this operator also.
Fixed a problem in AcpiUtInitializeBuffer where an existing buffer was not
initialized properly -- Now zero the entire buffer in this case where the
buffer already exists.
Changed the interface to AcpiOsSleep from (UINT32 Seconds, UINT32
Milliseconds) to simply (ACPI_INTEGER Milliseconds). This simplifies all
related code considerably. This will require changes/updates to all OS
interface layers (OSLs.)
Implemented a new external interface, AcpiInstallExceptionHandler, to allow
a system exception handler to be installed. This handler is invoked upon any
run-time exception that occurs during control method execution.
Added support for the DSDT in AcpiTbFindTable. This allows the
DataTableRegion() operator to access the local copy of the DSDT.
Code and Data Size: Current and previous core subsystem library sizes are
shown below. These are the code and data sizes for the acpica.lib produced
by the Microsoft Visual C++ 6.0 compiler, and these values do not include
any ACPI driver or OSPM code. The debug version of the code includes the
debug output trace mechanism and has a much larger code and data size. Note
that these values will vary depending on the efficiency of the compiler and
the compiler options used during generation.

Non-Debug Version: 77.9K Code, 11.4K Data, 89.3K Total
Debug Version: 164.5K Code, 68.3K Data, 232.8K Total
2) iASL Compiler/Disassembler:
Fixed a problem with constant folding and the LNot operator. LNot was
returning 1 in the TRUE case, not Ones as per the ACPI specification. This
could result in the generation of an incorrect folded/reduced constant.
End-Of-File is now allowed within a "//"-style comment. A parse error no
longer occurs if such a comment is at the very end of the input ASL source
file.
Implemented the "-r" option to override the Revision in the table header.
The initial use of this option will be to simplify the evaluation of the AML
interpreter by allowing a single ASL source module to be compiled for either
32-bit or 64-bit integers.
----------------------------------------
27 August 2004. Summary of changes for version 20040827:
1) ACPI CA Core Subsystem:
- Implemented support for implicit object conversion in the non-numeric
logical operators (LEqual, LGreater, LGreaterEqual, LLess, LLessEqual, and
LNotEqual.) Any combination of Integers/Strings/Buffers may now be used;
the second operand is implicitly converted on the fly to match the type of
the first operand. For example:
LEqual (Source1, Source2)
Source1 and Source2 must each evaluate to an integer, a string, or a buffer.
The data type of Source1 dictates the required type of Source2. Source2 is
implicitly converted if necessary to match the type of Source1.
- Updated and corrected the behavior of the string conversion support. The
rules concerning conversion of buffers to strings (according to the ACPI
specification) are as follows:
ToDecimalString - explicit byte-wise conversion of buffer to string of
decimal values (0-255) separated by commas. ToHexString - explicit byte-wise
conversion of buffer to string of hex values (0-FF) separated by commas.
ToString - explicit byte-wise conversion of buffer to string. Byte-by-byte
copy with no transform except NULL terminated. Any other implicit buffer-to-
string conversion - byte-wise conversion of buffer to string of hex values
(0-FF) separated by spaces.
- Fixed typo in definition of AcpiGbl_EnableInterpreterSlack.
- Fixed a problem in AcpiNsGetPathnameLength where the returned length was
one byte too short in the case of a node in the root scope. This could
cause a fault during debug output.
- Code and Data Size: Current and previous core subsystem library sizes are
shown below. These are the code and data sizes for the acpica.lib produced
by the Microsoft Visual C++ 6.0 compiler, and these values do not include
any ACPI driver or OSPM code. The debug version of the code includes the
debug output trace mechanism and has a much larger code and data size. Note
that these values will vary depending on the efficiency of the compiler and
the compiler options used during generation.

----------------------------------------
16 August 2004. Summary of changes for version 20040816:
1) ACPI CA Core Subsystem:
Designed and implemented support within the AML interpreter for the so-
called "implicit return". This support returns the result of the last ASL
operation within a control method, in the absence of an explicit Return()
operator. A few machines depend on this behavior, even though it is not
explicitly supported by the ASL language. It is optional support that can
be enabled at runtime via the AcpiGbl_EnableInterpreterSlack flag.
Removed support for the PCI_Config address space from the internal low level
hardware interfaces (AcpiHwLowLevelRead and AcpiHwLowLevelWrite). This
support was not used internally, and would not work correctly anyway because
the PCI bus number and segment number were not supported. There are
separate interfaces for PCI configuration space access because of the unique
interface.
Code and Data Size: Current and previous core subsystem library sizes are
shown below. These are the code and data sizes for the acpica.lib produced
by the Microsoft Visual C++ 6.0 compiler, and these values do not include
any ACPI driver or OSPM code. The debug version of the code includes the
debug output trace mechanism and has a much larger code and data size. Note
that these values will vary depending on the efficiency of the compiler and
the compiler options used during generation.

Debug Version: 164.1K Code, 68.3K Data, 232.4K Total
2) iASL Compiler/Disassembler:
Fixed a problem where constants in ASL expressions at the root level (not
within a control method) could be inadvertently truncated during code
generation. This problem was introduced in the 20040715 release.
----------------------------------------
15 July 2004. Summary of changes for version 20040715:
1) ACPI CA Core Subsystem:
Restructured the internal HW GPE interfaces to pass/track the current state
of interrupts (enabled/disabled) in order to avoid possible deadlock and
increase flexibility of the interfaces.
Implemented a "lexicographical compare" for String and Buffer objects within
the logical operators -- LGreater, LLess, LGreaterEqual, and LLessEqual --
as per further clarification to the ACPI specification. Behavior is similar
to C library "strcmp".
Completed a major reduction in CPU stack use for the AcpiGetFirmwareTable
external function. In the 32-bit non-debug case, the stack use has been
reduced from 168 bytes to 32 bytes.
Deployed a new run-time configuration flag, AcpiGbl_EnableInterpreterSlack,
whose purpose is to allow the AML interpreter to forgive certain bad AML
constructs. Default setting is FALSE.
Implemented the first use of AcpiGbl_EnableInterpreterSlack in the Field IO
support code. If enabled, it allows field access to go beyond the end of a
region definition if the field is within the region length rounded up to the
next access width boundary (a common coding error.)
Renamed OSD_HANDLER to ACPI_OSD_HANDLER, and OSD_EXECUTION_CALLBACK to
ACPI_OSD_EXEC_CALLBACK for consistency with other ACPI symbols. Also, these
symbols are lowercased by the latest version of the AcpiSrc tool.
The prototypes for the PCI interfaces in acpiosxf.h have been updated to
rename "Register" to simply "Reg" to prevent certain compilers from
complaining.
Code and Data Size: Current and previous core subsystem library sizes are
shown below. These are the code and data sizes for the acpica.lib produced
by the Microsoft Visual C++ 6.0 compiler, and these values do not include
any ACPI driver or OSPM code. The debug version of the code includes the
debug output trace mechanism and has a much larger code and data size. Note
that these values will vary depending on the efficiency of the compiler and
the compiler options used during generation.

2) iASL Compiler/Disassembler:
Implemented full support for Package objects within the Case() operator.
Note: The Break() operator is currently not supported within Case blocks
(TermLists) as there is some question about backward compatibility with ACPI
1.0 interpreters.
Fixed a problem where complex terms were not supported properly within the
Switch() operator.
Eliminated extraneous warning for compiler-emitted reserved names of the
form "_T_x". (Used in Switch/Case operators.)
Eliminated optimization messages for "_T_x" objects and small constants
within the DefinitionBlock operator.
----------------------------------------
15 June 2004. Summary of changes for version 20040615:
1) ACPI CA Core Subsystem:
Implemented support for Buffer and String objects (as per ACPI 2.0) for the
following ASL operators: LEqual, LGreater, LLess, LGreaterEqual, and
LLessEqual.
All directory names in the entire source package are lower case, as they
were in earlier releases.
Implemented "Disassemble" command in the AML debugger that will disassemble
a single control method.
Code and Data Size: Current and previous core subsystem library sizes are
shown below. These are the code and data sizes for the acpica.lib produced
by the Microsoft Visual C++ 6.0 compiler, and these values do not include
any ACPI driver or OSPM code. The debug version of the code includes the
debug output trace mechanism and has a much larger code and data size. Note
that these values will vary depending on the efficiency of the compiler and
the compiler options used during generation.

Debug Version: 163.3K Code, 67.2K Data, 230.5K Total
Current Release:
Non-Debug Version: 77.8K Code, 11.5K Data, 89.3K Total
Debug Version: 163.8K Code, 68.2K Data, 232.0K Total
2) iASL Compiler/Disassembler:
Implemented support for Buffer and String objects (as per ACPI 2.0) for the
following ASL operators: LEqual, LGreater, LLess, LGreaterEqual, and
LLessEqual.
All directory names in the entire source package are lower case, as they
were in earlier releases.
Fixed a fault when using the -g or -d<nofilename> options if the FADT was
not found.
Fixed an issue with the Windows version of the compiler where later versions
of Windows place the FADT in the registry under the name "FADT" and not
"FACP" as earlier versions did. This applies when using the -g or -
d<nofilename> options. The compiler now looks for both strings as
necessary.
Fixed a problem with compiler namepath optimization where a namepath within
the Scope() operator could not be optimized if the namepath was a subpath of
the current scope path.
----------------------------------------
27 May 2004. Summary of changes for version 20040527:
1) ACPI CA Core Subsystem:
Completed a new design and implementation for EBDA (Extended BIOS Data Area)
support in the RSDP scan code. The original code improperly scanned for the
EBDA by simply scanning from memory location 0 to 0x400. The correct method
is to first obtain the EBDA pointer from within the BIOS data area, then
scan 1K of memory starting at the EBDA pointer. There appear to be few if
any machines that place the RSDP in the EBDA, however.
Integrated a fix for a possible fault during evaluation of BufferField
arguments. Obsolete code that was causing the problem was removed.
Found and fixed a problem in the Field Support Code where data could be
corrupted on a bit field read that starts on an aligned boundary but does
not end on an aligned boundary. Merged the read/write "datum length"
calculation code into a common procedure.
Rolled in a couple of changes to the FreeBSD-specific header.
Code and Data Size: Current and previous core subsystem library sizes are
shown below. These are the code and data sizes for the acpica.lib produced
by the Microsoft Visual C++ 6.0 compiler, and these values do not include
any ACPI driver or OSPM code. The debug version of the code includes the
debug output trace mechanism and has a much larger code and data size. Note
that these values will vary depending on the efficiency of the compiler and
the compiler options used during generation.

2) iASL Compiler/Disassembler:
Fixed a generation warning produced by some overly-verbose compilers for a
64-bit constant.
----------------------------------------
14 May 2004. Summary of changes for version 20040514:
1) ACPI CA Core Subsystem:
Fixed a problem where hardware GPE enable bits sometimes not set properly
during and after GPE method execution. Result of 04/27 changes.
Removed extra "clear all GPEs" when sleeping/waking.
Removed AcpiHwEnableGpe and AcpiHwDisableGpe, replaced by the single
AcpiHwWriteGpeEnableReg. Changed a couple of calls to the functions above to
the new AcpiEv* calls as appropriate.
ACPI_OS_NAME was removed from the OS-specific headers. The default name is
now "Microsoft Windows NT" for maximum compatibility. However this can be
changed by modifying the acconfig.h file.
Allow a single invocation of AcpiInstallNotifyHandler for a handler that
traps both types of notifies (System, Device). Use ACPI_ALL_NOTIFY flag.
Run _INI methods on ThermalZone objects. This is against the ACPI
specification, but there is apparently ASL code in the field that has these
_INI methods, and apparently "other" AML interpreters execute them.
Performed a full 16/32/64 bit lint that resulted in some small changes.
Added a sleep simulation command to the AML debugger to test sleep code.
Code and Data Size: Current and previous core subsystem library sizes are
shown below. These are the code and data sizes for the acpica.lib produced
by the Microsoft Visual C++ 6.0 compiler, and these values do not include
any ACPI driver or OSPM code. The debug version of the code includes the

----------------------------------------
27 April 2004. Summary of changes for version 20040427:
1) ACPI CA Core Subsystem:
Completed a major overhaul of the GPE handling within ACPI CA. There are
now three types of GPEs: wake-only, runtime-only, and combination wake/run.
The only GPEs allowed to be combination wake/run are for button-style
devices such as a control-method power button, control-method sleep button,
or a notebook lid switch. GPEs that have an _Lxx or _Exx method and are not
referenced by any _PRW methods are marked for "runtime" and hardware
enabled. Any GPE that is referenced by a _PRW method is marked for "wake"
(and disabled at runtime). However, at sleep time, only those GPEs that
have been specifically enabled for wake via the AcpiEnableGpe interface will
actually be hardware enabled.
A new external interface has been added, AcpiSetGpeType(), that is meant to
be used by device drivers to force a GPE to a particular type. It will be
especially useful for the drivers for the button devices mentioned above.
Completed restructuring of the ACPI CA initialization sequence so that
default operation region handlers are installed before GPEs are initialized
and the _PRW methods are executed. This will prevent errors when the _PRW
methods attempt to access system memory or I/O space.
GPE enable/disable no longer reads the GPE enable register. We now keep the
enable info for runtime and wake separate and in the GPE_EVENT_INFO. We
thus no longer depend on the hardware to maintain these bits.
Always clear the wake status and fixed/GPE status bits before sleep, even
for state S5.
Improved the AML debugger output for displaying the GPE blocks and their
current status.
Added new strings for the _OSI method, of the form "Windows 2001 SPx" where
x = 0,1,2,3,4.
Fixed a problem where the physical address was incorrectly calculated when
the Load() operator was used to directly load from an Operation Region (vs.
loading from a Field object.) Also added check for minimum table length for
this case.
Fix for multiple mutex acquisition. Restore original thread SyncLevel on
mutex release.
Added ACPI_VALID_SXDS flag to the AcpiGetObjectInfo interface for
consistency with the other fields returned.
Shrunk the ACPI_GPE_EVENT_INFO structure by 40%. There is one such
structure for each GPE in the system, so the size of this structure is
important.
CPU stack requirement reduction: Cleaned up the method execution and object
evaluation paths so that now a parameter structure is passed, instead of
copying the various method parameters over and over again.
In evregion.c: Correctly exit and reenter the interpreter region if and
only if dispatching an operation region request to a user-installed handler.
Do not exit/reenter when dispatching to a default handler (e.g., default
system memory or I/O handlers)
Notes for updating drivers for the new GPE support. The following changes
must be made to ACPI-related device drivers that are attached to one or more
GPEs: (This information will be added to the ACPI CA Programmer Reference.)
1) AcpiInstallGpeHandler no longer automatically enables the GPE, you must
explicitly call AcpiEnableGpe.
2) There is a new interface called AcpiSetGpeType. This should be called
before enabling the GPE. Also, this interface will automatically disable
the GPE if it is currently enabled.
3) AcpiEnableGpe no longer supports a GPE type flag.
Specific drivers that must be changed:
1) EC driver:
AcpiInstallGpeHandler (NULL, GpeNum, ACPI_GPE_EDGE_TRIGGERED,
AeGpeHandler, NULL);
AcpiSetGpeType (NULL, GpeNum, ACPI_GPE_TYPE_RUNTIME);
AcpiEnableGpe (NULL, GpeNum, ACPI_NOT_ISR);
2) Button Drivers (Power, Lid, Sleep):
Run _PRW method under parent device
If _PRW exists: /* This is a control-method button */
Extract GPE number and possibly GpeDevice
AcpiSetGpeType (GpeDevice, GpeNum, ACPI_GPE_TYPE_WAKE_RUN);
AcpiEnableGpe (GpeDevice, GpeNum, ACPI_NOT_ISR);
For all other devices that have _PRWs, we automatically set the GPE type to
ACPI_GPE_TYPE_WAKE, but the GPE is NOT automatically (wake) enabled. This
must be done on a selective basis, usually requiring some kind of user app
to allow the user to pick the wake devices.
Code and Data Size: Current and previous core subsystem library sizes are
shown below. These are the code and data sizes for the acpica.lib produced
by the Microsoft Visual C++ 6.0 compiler, and these values do not include
any ACPI driver or OSPM code. The debug version of the code includes the

that these values will vary depending on the efficiency of the compiler and
the compiler options used during generation.

Debug Version: 162.9K Code, 67.0K Data, 229.9K Total
----------------------------------------
02 April 2004. Summary of changes for version 20040402:
1) ACPI CA Core Subsystem:
Fixed an interpreter problem where an indirect store through an ArgX
parameter was incorrectly applying the "implicit conversion rules" during
the store. From the ACPI specification: "If the target is a method local or
argument (LocalX or ArgX), no conversion is performed and the result is
stored directly to the target". The new behavior is to disable implicit
conversion during ALL stores to an ArgX.
Changed the behavior of the _PRW method scan to ignore any and all errors
returned by a given _PRW. This prevents the scan from aborting from the
failure of any single _PRW.
Moved the runtime configuration parameters from the global init procedure to
static variables in acglobal.h. This will allow the host to override the
default values easily.
Code and Data Size: Current and previous core subsystem library sizes are
shown below. These are the code and data sizes for the acpica.lib produced
by the Microsoft Visual C++ 6.0 compiler, and these values do not include
any ACPI driver or OSPM code. The debug version of the code includes the
debug output trace mechanism and has a much larger code and data size. Note
that these values will vary depending on the efficiency of the compiler and
the compiler options used during generation.

Non-Debug Version: 77.0K Code, 11.4K Data, 88.4K Total
Debug Version: 161.0K Code, 66.3K Data, 227.3K Total
2) iASL Compiler/Disassembler:
iASL now fully disassembles SSDTs. However, External() statements are not
generated automatically for unresolved symbols at this time. This is a
planned feature for future implementation.
Fixed a scoping problem in the disassembler that occurs when the type of the
target of a Scope() operator is overridden. This problem caused an
incorrectly nested internal namespace to be constructed.
Any warnings or errors that are emitted during disassembly are now commented
out automatically so that the resulting file can be recompiled without any
hand editing.
----------------------------------------
26 March 2004. Summary of changes for version 20040326:
1) ACPI CA Core Subsystem:
Implemented support for "wake" GPEs via interaction between GPEs and the
_PRW methods. Every GPE that is pointed to by one or more _PRWs is
identified as a WAKE GPE and by default will no longer be enabled at
runtime. Previously, we were blindly enabling all GPEs with a corresponding
_Lxx or _Exx method - but most of these turn out to be WAKE GPEs anyway. We
believe this has been the cause of thousands of "spurious" GPEs on some
systems.
This new GPE behavior is can be reverted to the original behavior (enable
ALL GPEs at runtime) via a runtime flag.
Fixed a problem where aliased control methods could not access objects
properly. The proper scope within the namespace was not initialized
(transferred to the target of the aliased method) before executing the
target method.
Fixed a potential race condition on internal object deletion on the return
object in AcpiEvaluateObject.
Integrated a fix for resource descriptors where both _MEM and _MTP were
being extracted instead of just _MEM. (i.e. bitmask was incorrectly too
wide, 0x0F instead of 0x03.)
Added a special case for ACPI_ROOT_OBJECT in AcpiUtGetNodeName, preventing a
fault in some cases.
Updated Notify() values for debug statements in evmisc.c
Return proper status from AcpiUtMutexInitialize, not just simply AE_OK.
Code and Data Size: Current and previous core subsystem library sizes are
shown below. These are the code and data sizes for the acpica.lib produced
by the Microsoft Visual C++ 6.0 compiler, and these values do not include
any ACPI driver or OSPM code. The debug version of the code includes the
debug output trace mechanism and has a much larger code and data size. Note
that these values will vary depending on the efficiency of the compiler and
the compiler options used during generation.

----------------------------------------
11 March 2004. Summary of changes for version 20040311:
1) ACPI CA Core Subsystem:
Fixed a problem where errors occurring during the parse phase of control
method execution did not abort cleanly. For example, objects created and
installed in the namespace were not deleted. This caused all subsequent
invocations of the method to return the AE_ALREADY_EXISTS exception.
Implemented a mechanism to force a control method to "Serialized" execution
if the method attempts to create namespace objects. (The root of the
AE_ALREADY_EXISTS problem.)
Implemented support for the predefined _OSI "internal" control method.
Initial supported strings are "Linux", "Windows 2000", "Windows 2001", and
"Windows 2001.1", and can be easily upgraded for new strings as necessary.
This feature will allow "other" operating systems to execute the fully
tested, "Windows" code path through the ASL code
Global Lock Support: Now allows multiple acquires and releases with any
internal thread. Removed concept of "owning thread" for this special mutex.
Fixed two functions that were inappropriately declaring large objects on the
CPU stack: PsParseLoop, NsEvaluateRelative. Reduces the stack usage during
method execution considerably.
Fixed a problem in the ACPI 2.0 FACS descriptor (actbl2.h) where the
S4Bios_f field was incorrectly defined as UINT32 instead of UINT32_BIT.
Fixed a problem where AcpiEvGpeDetect would fault if there were no GPEs
defined on the machine.
Implemented two runtime options: One to force all control method execution
to "Serialized" to mimic Windows behavior, another to disable _OSI support
if it causes problems on a given machine.
Code and Data Size: Current and previous core subsystem library sizes are
shown below. These are the code and data sizes for the acpica.lib produced
by the Microsoft Visual C++ 6.0 compiler, and these values do not include
any ACPI driver or OSPM code. The debug version of the code includes the
debug output trace mechanism and has a much larger code and data size. Note
that these values will vary depending on the efficiency of the compiler and
the compiler options used during generation.

fault.
----------------------------------------
20 February 2004. Summary of changes for version 20040220:
1) ACPI CA Core Subsystem:
Implemented execution of _SxD methods for Device objects in the
GetObjectInfo interface.
Fixed calls to _SST method to pass the correct arguments.
Added a call to _SST on wake to restore to "working" state.
Check for End-Of-Buffer failure case in the WalkResources interface.
Integrated fix for 64-bit alignment issue in acglobal.h by moving two
structures to the beginning of the file.
After wake, clear GPE status register(s) before enabling GPEs.
After wake, clear/enable power button. (Perhaps we should clear/enable all
fixed events upon wake.)
Fixed a couple of possible memory leaks in the Namespace manager.
Integrated latest acnetbsd.h file.
----------------------------------------
11 February 2004. Summary of changes for version 20040211:
1) ACPI CA Core Subsystem:
Completed investigation and implementation of the call-by-reference
mechanism for control method arguments.
Fixed a problem where a store of an object into an indexed package could
fail if the store occurs within a different method than the method that
created the package.
Fixed a problem where the ToDecimal operator could return incorrect results.
Fixed a problem where the CopyObject operator could fail on some of the more
obscure objects (e.g., Reference objects.)
Improved the output of the Debug object to display buffer, package, and
index objects.
Fixed a problem where constructs of the form "RefOf (ArgX)" did not return
the expected result.
Added permanent ACPI_REPORT_ERROR macros for all instances of the
ACPI_AML_INTERNAL exception.
Integrated latest version of acfreebsd.h
----------------------------------------
16 January 2004. Summary of changes for version 20040116:
The purpose of this release is primarily to update the copyright years in
each module, thus causing a huge number of diffs. There are a few small
functional changes, however.
1) ACPI CA Core Subsystem:
Improved error messages when there is a problem finding one or more of the
required base ACPI tables
Reintroduced the definition of APIC_HEADER in actbl.h
Changed definition of MADT_ADDRESS_OVERRIDE to 64 bits (actbl.h)
Removed extraneous reference to NewObj in dsmthdat.c
2) iASL compiler
Fixed a problem introduced in December that disabled the correct disassembly
of Resource Templates
----------------------------------------
03 December 2003. Summary of changes for version 20031203:
1) ACPI CA Core Subsystem:
Changed the initialization of Operation Regions during subsystem
init to perform two entire walks of the ACPI namespace; The first
to initialize the regions themselves, the second to execute the
_REG methods. This fixed some interdependencies across _REG
methods found on some machines.
Fixed a problem where a Store(Local0, Local1) could simply update
the object reference count, and not create a new copy of the
object if the Local1 is uninitialized.
Implemented support for the _SST reserved method during sleep
transitions.
Implemented support to clear the SLP_TYP and SLP_EN bits when
waking up, this is apparently required by some machines.
When sleeping, clear the wake status only if SleepState is not S5.
Fixed a problem in AcpiRsExtendedIrqResource() where an incorrect
pointer arithmetic advanced a string pointer too far.
Fixed a problem in AcpiTbGetTablePtr() where a garbage pointer
could be returned if the requested table has not been loaded.
Within the support for IRQ resources, restructured the handling of
the active and edge/level bits.
Fixed a few problems in AcpiPsxExecute() where memory could be
leaked under certain error conditions.
Improved error messages for the cases where the ACPI mode could
not be entered.
Code and Data Size: Current and previous core subsystem library
sizes are shown below. These are the code and data sizes for the
acpica.lib produced by the Microsoft Visual C++ 6.0 compiler, and
these values do not include any ACPI driver or OSPM code. The

these values will vary depending on the efficiency of the compiler
and the compiler options used during generation.

2) iASL Compiler/Disassembler:

generated. This was most noticeable on 64-bit platforms
----------------------------------------
29 October 2003. Summary of changes for version 20031029:
1) ACPI CA Core Subsystem:
Fixed a problem where a level-triggered GPE with an associated
_Lxx control method was incorrectly cleared twice.
Fixed a problem with the Field support code where an access can
occur beyond the end-of-region if the field is non-aligned but
extends to the very end of the parent region (resulted in an
AE_AML_REGION_LIMIT exception.)
Fixed a problem with ACPI Fixed Events where an RT Clock handler
would not get invoked on an RTC event. The RTC event bitmasks for
the PM1 registers were not being initialized properly.
Implemented support for executing _STA and _INI methods for
Processor objects. Although this is currently not part of the
ACPI specification, there is existing ASL code that depends on the
init-time execution of these methods.
Implemented and deployed a GetDescriptorName function to decode
the various types of internal descriptors. Guards against null
descriptors during debug output also.
Implemented and deployed a GetNodeName function to extract the 4-
character namespace node name. This function simplifies the debug
and error output, as well as guarding against null pointers during
output.
Implemented and deployed the ACPI_FORMAT_UINT64 helper macro to
simplify the debug and error output of 64-bit integers. This
macro replaces the HIDWORD and LODWORD macros for dumping these
integers.
Updated the implementation of the Stall() operator to only call
AcpiOsStall(), and also return an error if the operand is larger
than 255. This preserves the required behavior of not
relinquishing the processor, as would happen if AcpiOsSleep() was
called for "long stalls".
Constructs of the form "Store(LocalX,LocalX)" where LocalX is not
initialized are now treated as NOOPs.
Cleaned up a handful of warnings during 64-bit generation.
Fixed a reported error where and incorrect GPE number was passed
to the GPE dispatch handler. This value is only used for error
output, however. Used this opportunity to clean up and streamline
the GPE dispatch code.
Code and Data Size: Current and previous core subsystem library
sizes are shown below. These are the code and data sizes for the
acpica.lib produced by the Microsoft Visual C++ 6.0 compiler, and
these values do not include any ACPI driver or OSPM code. The
debug version of the code includes the debug output trace
mechanism and has a much larger code and data size. Note that
these values will vary depending on the efficiency of the compiler
and the compiler options used during generation.

----------------------------------------
02 October 2003. Summary of changes for version 20031002:
1) ACPI CA Core Subsystem:
Fixed a problem with Index Fields where the index was not
incremented for fields that require multiple writes to the
index/data registers (Fields that are wider than the data
register.)
Fixed a problem with all Field objects where a write could go
beyond the end-of-field if the field was larger than the access
granularity and therefore required multiple writes to complete the
request. An extra write beyond the end of the field could happen
inadvertently.
Fixed a problem with Index Fields where a BUFFER_OVERFLOW error
would incorrectly be returned if the width of the Data Register
was larger than the specified field access width.
Completed fixes for LoadTable() and Unload() and verified their
operation. Implemented full support for the "DdbHandle" object
throughout the ACPI CA subsystem.
Implemented full support for the MADT and ECDT tables in the ACPI
CA header files. Even though these tables are not directly
consumed by ACPI CA, the header definitions are useful for ACPI
device drivers.
Integrated resource descriptor fixes posted to the Linux ACPI
list. This included checks for minimum descriptor length, and
support for trailing NULL strings within descriptors that have
optional string elements.
Code and Data Size: Current and previous core subsystem library
sizes are shown below. These are the code and data sizes for the
acpica.lib produced by the Microsoft Visual C++ 6.0 compiler, and

2) iASL Compiler:
Implemented detection of non-ASCII characters within the input
source ASL file. This catches attempts to compile binary (AML)
files early in the compile, with an informative error message.
Fixed a problem where the disassembler would fault if the output
filename could not be generated or if the output file could not be
opened.
----------------------------------------
18 September 2003. Summary of changes for version 20030918:
1) ACPI CA Core Subsystem:
Found and fixed a longstanding problem with the late execution of
the various deferred AML opcodes (such as Operation Regions,
Buffer Fields, Buffers, and Packages). If the name string
specified for the name of the new object placed the object in a
scope other than the current scope, the initialization/execution
of the opcode failed. The solution to this problem was to
implement a mechanism where the late execution of such opcodes
does not attempt to lookup/create the name a second time in an
incorrect scope. This fixes the "region size computed
incorrectly" problem.
Fixed a call to AcpiHwRegisterWrite in hwregs.c that was causing a
Global Lock AE_BAD_PARAMETER error.
Fixed several 64-bit issues with prototypes, casting and data
types.
Removed duplicate prototype from acdisasm.h
Fixed an issue involving EC Operation Region Detach (Shaohua Li)

these values will vary depending on the efficiency of the compiler
and the compiler options used during generation.

----------------------------------------
22 May 2003. Summary of changes for version 20030522:
1) ACPI CA Core Subsystem:
Found and fixed a reported problem where an AE_NOT_FOUND error
occurred occasionally during _BST evaluation. This turned out to
be an Owner ID allocation issue where a called method did not get
a new ID assigned to it. Eventually, (after 64k calls), the Owner
ID UINT16 would wraparound so that the ID would be the same as the
caller's and the called method would delete the caller's
namespace.
Implemented extended error reporting for control methods that are
aborted due to a run-time exception. Output includes the exact
AML instruction that caused the method abort, a dump of the method
locals and arguments at the time of the abort, and a trace of all
nested control method calls.
Modified the interpreter to allow the creation of buffers of zero
length from the AML code. Implemented new code to ensure that no
attempt is made to actually allocate a memory buffer (of length
zero) - instead, a simple buffer object with a NULL buffer pointer
and length zero is created. A warning is no longer issued when
the AML attempts to create a zero-length buffer.
Implemented a workaround for the "leading asterisk issue" in
_HIDs, _UIDs, and _CIDs in the AML interpreter. One leading
asterisk is automatically removed if present in any HID, UID, or
CID strings. The iASL compiler will still flag this asterisk as
an error, however.
Implemented full support for _CID methods that return a package of
multiple CIDs (Compatible IDs). The AcpiGetObjectInfo() interface
now additionally returns a device _CID list if present. This
required a change to the external interface in order to pass an
ACPI_BUFFER object as a parameter since the _CID list is of
variable length.
Fixed a problem with the new AE_SAME_HANDLER exception where
handler initialization code did not know about this exception.
Code and Data Size: Current and previous core subsystem library
sizes are shown below. These are the code and data sizes for the
acpica.lib produced by the Microsoft Visual C++ 6.0 compiler, and
these values do not include any ACPI driver or OSPM code. The
debug version of the code includes the debug output trace
mechanism and has a much larger code and data size. Note that
these values will vary depending on the efficiency of the compiler
and the compiler options used during generation.

2) Linux:
Fixed a bug in which we would reinitialize the ACPI interrupt
after it was already working, thus disabling all ACPI and the IRQs
for any other device sharing the interrupt. (Thanks to Stian
Jordet)
Toshiba driver update (John Belmonte)
Return only 0 or 1 for our interrupt handler status (Andrew
Morton)
3) iASL Compiler:
Fixed a reported problem where multiple (nested) ElseIf()
statements were not handled correctly by the compiler, resulting
in incorrect warnings and incorrect AML code. This was a problem
in both the ASL parser and the code generator.
4) Documentation:
Added changes to existing interfaces, new exception codes, and new
text concerning reference count object management versus garbage
collection.
----------------------------------------
09 May 2003. Summary of changes for version 20030509.
1) ACPI CA Core Subsystem:
Changed the subsystem initialization sequence to hold off
installation of address space handlers until the hardware has been
initialized and the system has entered ACPI mode. This is because
the installation of space handlers can cause _REG methods to be
run. Previously, the _REG methods could potentially be run before
ACPI mode was enabled.
Fixed some memory leak issues related to address space handler and
notify handler installation. There were some problems with the
reference count mechanism caused by the fact that the handler
objects are shared across several namespace objects.
Fixed a reported problem where reference counts within the
namespace were not properly updated when named objects created by
method execution were deleted.
Fixed a reported problem where multiple SSDTs caused a deletion
issue during subsystem termination. Restructured the table data
structures to simplify the linked lists and the related code.
Fixed a problem where the table ID associated with secondary
tables (SSDTs) was not being propagated into the namespace objects
created by those tables. This would only present a problem for
tables that are unloaded at run-time, however.
Updated AcpiOsReadable and AcpiOsWritable to use the ACPI_SIZE
type as the length parameter (instead of UINT32).
Solved a long-standing problem where an ALREADY_EXISTS error
appears on various systems. This problem could happen when there
are multiple PCI_Config operation regions under a single PCI root
bus. This doesn't happen very frequently, but there are some
systems that do this in the ASL.
Fixed a reported problem where the internal DeleteNode function
was incorrectly handling the case where a namespace node was the
first in the parent's child list, and had additional peers (not
the only child, but first in the list of children.)
Code and Data Size: Current core subsystem library sizes are shown
below. These are the code and data sizes for the acpica.lib
produced by the Microsoft Visual C++ 6.0 compiler, and these
values do not include any ACPI driver or OSPM code. The debug
version of the code includes the debug output trace mechanism and
has a much larger code and data size. Note that these values will
vary depending on the efficiency of the compiler and the compiler
options used during generation.

2) Linux:
Allow ":" in OS override string (Ducrot Bruno)
Kobject fix (Greg KH)
3 iASL Compiler/Disassembler:
Fixed a problem in the generation of the C source code files (AML
is emitted in C source statements for BIOS inclusion) where the
Ascii dump that appears within a C comment at the end of each line
could cause a compile time error if the AML sequence happens to
have an open comment or close comment sequence embedded.
----------------------------------------
24 April 2003. Summary of changes for version 20030424.
1) ACPI CA Core Subsystem:
Support for big-endian systems has been implemented. Most of the
support has been invisibly added behind big-endian versions of the
ACPI_MOVE_* macros.
Fixed a problem in AcpiHwDisableGpeBlock() and
AcpiHwClearGpeBlock() where an incorrect offset was passed to the
low level hardware write routine. The offset parameter was
actually eliminated from the low level read/write routines because
they had become obsolete.
Fixed a problem where a handler object was deleted twice during
the removal of a fixed event handler.
2) Linux:
A fix for SMP systems with link devices was contributed by
Compaq's Dan Zink.
(2.5) Return whether we handled the interrupt in our IRQ handler.
(Linux ISRs no longer return void, so we can propagate the handler
return value from the ACPI CA core back to the OS.)
3) Documentation:
The ACPI CA Programmer Reference has been updated to reflect new
interfaces and changes to existing interfaces.
----------------------------------------
28 March 2003. Summary of changes for version 20030328.
1) ACPI CA Core Subsystem:
The GPE Block Device support has been completed. New interfaces
are AcpiInstallGpeBlock and AcpiRemoveGpeBlock. The Event
interfaces (enable, disable, clear, getstatus) have been split
into separate interfaces for Fixed Events and General Purpose
Events (GPEs) in order to support GPE Block Devices properly.
Fixed a problem where the error message "Failed to acquire
semaphore" would appear during operations on the embedded
controller (EC).
Code and Data Size: Current core subsystem library sizes are shown
below. These are the code and data sizes for the acpica.lib
produced by the Microsoft Visual C++ 6.0 compiler, and these
values do not include any ACPI driver or OSPM code. The debug
version of the code includes the debug output trace mechanism and
has a much larger code and data size. Note that these values will
vary depending on the efficiency of the compiler and the compiler
options used during generation.

----------------------------------------
28 February 2003. Summary of changes for version 20030228.
1) ACPI CA Core Subsystem:
The GPE handling and dispatch code has been completely overhauled
in preparation for support of GPE Block Devices (ID ACPI0006).
This affects internal data structures and code only; there should
be no differences visible externally. One new file has been
added, evgpeblk.c
The FADT fields GPE0_BLK_LEN and GPE1_BLK_LEN are now the only
fields that are used to determine the GPE block lengths. The
REGISTER_BIT_WIDTH field of the X_GPEx_BLK extended address
structures are ignored. This is per the ACPI specification but it
isn't very clear. The full 256 Block 0/1 GPEs are now supported
(the use of REGISTER_BIT_WIDTH limited the number of GPEs to 128).
In the SCI interrupt handler, removed the read of the PM1_CONTROL
register to look at the SCI_EN bit. On some machines, this read
causes an SMI event and greatly slows down SCI events. (This may
in fact be the cause of slow battery status response on some
systems.)
Fixed a problem where a store of a NULL string to a package object
could cause the premature deletion of the object. This was seen
during execution of the battery _BIF method on some systems,
resulting in no battery data being returned.
Added AcpiWalkResources interface to simplify parsing of resource
lists.
Code and Data Size: Current core subsystem library sizes are shown
below. These are the code and data sizes for the acpica.lib
produced by the Microsoft Visual C++ 6.0 compiler, and these
values do not include any ACPI driver or OSPM code. The debug
version of the code includes the debug output trace mechanism and
has a much larger code and data size. Note that these values will
vary depending on the efficiency of the compiler and the compiler
options used during generation.

2) Linux
S3 fixes (Ole Rohne)
Update ACPI PHP driver with to use new acpi_walk_resource API
(Bjorn Helgaas)
Add S4BIOS support (Pavel Machek)
Map in entire table before performing checksum (John Stultz)
Expand the mem= cmdline to allow the specification of reserved and
ACPI DATA blocks (Pavel Machek)
Never use ACPI on VISWS
Fix derive_pci_id (Ducrot Bruno, Alvaro Lopez)
Revert a change that allowed P_BLK lengths to be 4 or 5. This is
causing us to think that some systems support C2 when they really
don't.
Do not count processor objects for non-present CPUs (Thanks to
Dominik Brodowski)
3) iASL Compiler:
Fixed a problem where ASL include files could not be found and
opened.
Added support for the _PDC reserved name.
----------------------------------------
22 January 2003. Summary of changes for version 20030122.
1) ACPI CA Core Subsystem:
Added a check for constructs of the form: Store (Local0, Local0)
where Local0 is not initialized. Apparently, some BIOS
programmers believe that this is a NOOP. Since this store doesn't
do anything anyway, the new prototype behavior will ignore this
error. This is a case where we can relax the strict checking in
the interpreter in the name of compatibility.
2) Linux
The AcpiSrc Source Conversion Utility has been released with the
Linux package for the first time. This is the utility that is
used to convert the ACPI CA base source code to the Linux version.
(Both) Handle P_BLK lengths shorter than 6 more gracefully
(Both) Move more headers to include/acpi, and delete an unused
header.
(Both) Move drivers/acpi/include directory to include/acpi
(Both) Boot functions don't use cmdline, so don't pass it around
(Both) Remove include of unused header (Adrian Bunk)
(Both) acpiphp.h includes both linux/acpi.h and acpi_bus.h. Since
the
former now also includes the latter, acpiphp.h only needs the one,
now.
(2.5) Make it possible to select method of bios restoring after S3
resume. [=> no more ugly ifdefs] (Pavel Machek)
(2.5) Make proc write interfaces work (Pavel Machek)
(2.5) Properly init/clean up in cpufreq/acpi (Dominik Brodowski)
(2.5) Break out ACPI Perf code into its own module, under cpufreq
(Dominik Brodowski)
(2.4) S4BIOS support (Ducrot Bruno)
(2.4) Fix acpiphp_glue.c for latest ACPI struct changes (Sergio
Visinoni)
3) iASL Compiler:
Added support to disassemble SSDT and PSDTs.
Implemented support to obtain SSDTs from the Windows registry if
available.
----------------------------------------
09 January 2003. Summary of changes for version 20030109.
1) ACPI CA Core Subsystem:
Changed the behavior of the internal Buffer-to-String conversion
function. The current ACPI specification states that the contents
of the buffer are "converted to a string of two-character
hexadecimal numbers, each separated by a space". Unfortunately,
this definition is not backwards compatible with existing ACPI 1.0
implementations (although the behavior was not defined in the ACPI
1.0 specification). The new behavior simply copies data from the
buffer to the string until a null character is found or the end of
the buffer is reached. The new String object is always null
terminated. This problem was seen during the generation of _BIF
battery data where incorrect strings were returned for battery
type, etc. This will also require an errata to the ACPI
specification.
Renamed all instances of NATIVE_UINT and NATIVE_INT to
ACPI_NATIVE_UINT and ACPI_NATIVE_INT, respectively.
Copyright in all module headers (both Linux and non-Linux) has be
updated to 2003.
Code and Data Size: Current core subsystem library sizes are shown
below. These are the code and data sizes for the acpica.lib
produced by the Microsoft Visual C++ 6.0 compiler, and these
values do not include any ACPI driver or OSPM code. The debug
version of the code includes the debug output trace mechanism and
has a much larger code and data size. Note that these values will
vary depending on the efficiency of the compiler and the compiler
options used during generation.

2) Linux
Fixed an oops on module insertion/removal (Matthew Tippett)
(2.4) Fix to handle dynamic size of mp_irqs (Joerg Prante)
(2.5) Replace pr_debug (Randy Dunlap)
(2.5) Remove usage of CPUFREQ_ALL_CPUS (Dominik Brodowski)
(Both) Eliminate spawning of thread from timer callback, in favor
of schedule_work()
(Both) Show Lid status in /proc (Zdenek OGAR Skalak)
(Both) Added define for Fixed Function HW region (Matthew Wilcox)
(Both) Add missing statics to button.c (Pavel Machek)
Several changes have been made to the source code translation
utility that generates the Linux Code in order to make the code
more "Linux-like":
All typedefs on structs and unions have been removed in keeping
with the Linux coding style.
Removed the non-Linux SourceSafe module revision number from each
module header.
Completed major overhaul of symbols to be lowercased for linux.
Doubled the number of symbols that are lowercased.
Fixed a problem where identifiers within procedure headers and
within quotes were not fully lower cased (they were left with a
starting capital.)
Some C macros whose only purpose is to allow the generation of 16-
bit code are now completely removed in the Linux code, increasing
readability and maintainability.
----------------------------------------
12 December 2002. Summary of changes for version 20021212.
1) ACPI CA Core Subsystem:
Fixed a problem where the creation of a zero-length AML Buffer
would cause a fault.
Fixed a problem where a Buffer object that pointed to a static AML
buffer (in an ACPI table) could inadvertently be deleted, causing
memory corruption.
Fixed a problem where a user buffer (passed in to the external
ACPI CA interfaces) could be overwritten if the buffer was too
small to complete the operation, causing memory corruption.
Fixed a problem in the Buffer-to-String conversion code where a
string of length one was always returned, regardless of the size
of the input Buffer object.
Removed the NATIVE_CHAR data type across the entire source due to
lack of need and lack of consistent use.
Code and Data Size: Current core subsystem library sizes are shown
below. These are the code and data sizes for the acpica.lib
produced by the Microsoft Visual C++ 6.0 compiler, and these
values do not include any ACPI driver or OSPM code. The debug

----------------------------------------
05 December 2002. Summary of changes for version 20021205.
1) ACPI CA Core Subsystem:
Fixed a problem where a store to a String or Buffer object could
cause corruption of the DSDT if the object type being stored was
the same as the target object type and the length of the object
being stored was equal to or smaller than the original (existing)
target object. This was seen to cause corruption of battery _BIF
buffers if the _BIF method modified the buffer on the fly.
Fixed a problem where an internal error was generated if a control
method invocation was used in an OperationRegion, Buffer, or
Package declaration. This was caused by the deferred parsing of
the control method and thus the deferred creation of the internal
method object. The solution to this problem was to create the
internal method object at the moment the method is encountered in
the first pass - so that subsequent references to the method will
able to obtain the required parameter count and thus properly
parse the method invocation. This problem presented itself as an
AE_AML_INTERNAL during the pass 1 parse phase during table load.
Fixed a problem where the internal String object copy routine did
not always allocate sufficient memory for the target String object
and caused memory corruption. This problem was seen to cause
"Allocation already present in list!" errors as memory allocation
became corrupted.
Implemented a new function for the evaluation of namespace objects
that allows the specification of the allowable return object
types. This simplifies a lot of code that checks for a return
object of one or more specific objects returned from the
evaluation (such as _STA, etc.) This may become and external
function if it would be useful to ACPI-related drivers.
Completed another round of prefixing #defines with "ACPI_" for
clarity.
Completed additional code restructuring to allow more modular
linking for iASL compiler and AcpiExec. Several files were split
creating new files. New files: nsparse.c dsinit.c evgpe.c
Implemented an abort mechanism to terminate an executing control
method via the AML debugger. This feature is useful for debugging
control methods that depend (wait) for specific hardware
responses.
Code and Data Size: Current core subsystem library sizes are shown
below. These are the code and data sizes for the acpica.lib
produced by the Microsoft Visual C++ 6.0 compiler, and these
values do not include any ACPI driver or OSPM code. The debug
version of the code includes the debug output trace mechanism and
has a much larger code and data size. Note that these values will
vary depending on the efficiency of the compiler and the compiler
options used during generation.

2) iASL Compiler/Disassembler
Fixed a compiler code generation problem for "Interrupt" Resource
Descriptors. If specified in the ASL, the optional "Resource
Source Index" and "Resource Source" fields were not inserted into
the correct location within the AML resource descriptor, creating
an invalid descriptor.
Fixed a disassembler problem for "Interrupt" resource descriptors.
The optional "Resource Source Index" and "Resource Source" fields
were ignored.
----------------------------------------
22 November 2002. Summary of changes for version 20021122.
1) ACPI CA Core Subsystem:
Fixed a reported problem where an object stored to a Method Local
or Arg was not copied to a new object during the store - the
object pointer was simply copied to the Local/Arg. This caused
all subsequent operations on the Local/Arg to also affect the
original source of the store operation.
Fixed a problem where a store operation to a Method Local or Arg
was not completed properly if the Local/Arg contained a reference
(from RefOf) to a named field. The general-purpose store-to-
namespace-node code is now used so that this case is handled
automatically.
Fixed a problem where the internal object copy routine would cause
a protection fault if the object being copied was a Package and
contained either 1) a NULL package element or 2) a nested sub-
package.
Fixed a problem with the GPE initialization that resulted from an
ambiguity in the ACPI specification. One section of the
specification states that both the address and length of the GPE
block must be zero if the block is not supported. Another section
implies that only the address need be zero if the block is not
supported. The code has been changed so that both the address and
the length must be non-zero to indicate a valid GPE block (i.e.,
if either the address or the length is zero, the GPE block is
invalid.)
Code and Data Size: Current core subsystem library sizes are shown
below. These are the code and data sizes for the acpica.lib
produced by the Microsoft Visual C++ 6.0 compiler, and these
values do not include any ACPI driver or OSPM code. The debug
version of the code includes the debug output trace mechanism and
has a much larger code and data size. Note that these values will
vary depending on the efficiency of the compiler and the compiler
options used during generation.

2) Linux
Cleaned up EC driver. Exported an external EC read/write
interface. By going through this, other drivers (most notably
sonypi) will be able to serialize access to the EC.
3) iASL Compiler/Disassembler
Implemented support to optionally generate include files for both
ASM and C (the -i switch). This simplifies BIOS development by
automatically creating include files that contain external
declarations for the symbols that are created within the
(optionally generated) ASM and C AML source files.
----------------------------------------
15 November 2002. Summary of changes for version 20021115.
1) ACPI CA Core Subsystem:
Fixed a memory leak problem where an error during resolution of
method arguments during a method invocation from another method
failed to cleanup properly by deleting all successfully resolved
argument objects.
Fixed a problem where the target of the Index() operator was not
correctly constructed if the source object was a package. This
problem has not been detected because the use of a target operand
with Index() is very rare.
Fixed a problem with the Index() operator where an attempt was
made to delete the operand objects twice.
Fixed a problem where an attempt was made to delete an operand
twice during execution of the CondRefOf() operator if the target
did not exist.
Implemented the first of perhaps several internal create object
functions that create and initialize a specific object type. This
consolidates duplicated code wherever the object is created, thus
shrinking the size of the subsystem.
Implemented improved debug/error messages for errors that occur
during nested method invocations. All executing method pathnames
are displayed (with the error) as the call stack is unwound - thus
simplifying debug.
Fixed a problem introduced in the 10/02 release that caused
premature deletion of a buffer object if a buffer was used as an
ASL operand where an integer operand is required (Thus causing an
implicit object conversion from Buffer to Integer.) The change in
the 10/02 release was attempting to fix a memory leak (albeit
incorrectly.)
Code and Data Size: Current core subsystem library sizes are shown
below. These are the code and data sizes for the acpica.lib
produced by the Microsoft Visual C++ 6.0 compiler, and these
values do not include any ACPI driver or OSPM code. The debug

vary depending on the efficiency of the compiler and the compiler
options used during generation.

Debug Version: 152.7K Code, 63.2K Data, 215.5K Total
2) Linux
Changed the implementation of the ACPI semaphores to use down()
instead of down_interruptable(). It is important that the
execution of ACPI control methods not be interrupted by signals.
Methods must run to completion, or the system may be left in an
unknown/unstable state.
Fixed a compilation error when CONFIG_SOFTWARE_SUSPEND is not set.
(Shawn Starr)
3) iASL Compiler/Disassembler
Changed the default location of output files. All output files
are now placed in the current directory by default instead of in
the directory of the source file. This change may affect some
existing makefiles, but it brings the behavior of the compiler in
line with other similar tools. The location of the output files
can be overridden with the -p command line switch.

Implemented support for the ACPI 2.0 SMBus Operation Regions.
This includes the early detection and handoff of the request to
the SMBus region handler (avoiding all of the complex field
support code), and support for the bidirectional return packet
from an SMBus write operation. This paves the way for the
development of SMBus drivers in each host operating system.
Fixed a problem where the semaphore WAIT_FOREVER constant was
defined as 32 bits, but must be 16 bits according to the ACPI
specification. This had the side effect of causing ASL
Mutex/Event timeouts even though the ASL code requested a wait
forever. Changed all internal references to the ACPI timeout
parameter to 16 bits to prevent future problems. Changed the name
of WAIT_FOREVER to ACPI_WAIT_FOREVER.
Code and Data Size: Current core subsystem library sizes are shown
below. These are the code and data sizes for the acpica.lib
produced by the Microsoft Visual C++ 6.0 compiler, and these
values do not include any ACPI driver or OSPM code. The debug
version of the code includes the debug output trace mechanism and
has a much larger code and data size. Note that these values will
vary depending on the efficiency of the compiler and the compiler
options used during generation.

----------------------------------------
01 November 2002. Summary of changes for version 20021101.
1) ACPI CA Core Subsystem:
Fixed a problem where platforms that have a GPE1 block but no GPE0
block were not handled correctly. This resulted in a "GPE
overlap" error message. GPE0 is no longer required.
Removed code added in the previous release that inserted nodes
into the namespace in alphabetical order. This caused some side-
effects on various machines. The root cause of the problem is
still under investigation since in theory, the internal ordering
of the namespace nodes should not matter.
Enhanced error reporting for the case where a named object is not
found during control method execution. The full ACPI namepath
(name reference) of the object that was not found is displayed in
this case.
Note: as a result of the overhaul of the namespace object types in
the previous release, the namespace nodes for the predefined
scopes (_TZ, _PR, etc.) are now of the type ACPI_TYPE_LOCAL_SCOPE
instead of ACPI_TYPE_ANY. This simplifies the namespace
management code but may affect code that walks the namespace tree
looking for specific object types.
Code and Data Size: Current core subsystem library sizes are shown
below. These are the code and data sizes for the acpica.lib
produced by the Microsoft Visual C++ 6.0 compiler, and these
values do not include any ACPI driver or OSPM code. The debug
version of the code includes the debug output trace mechanism and
has a much larger code and data size. Note that these values will
vary depending on the efficiency of the compiler and the compiler
options used during generation.

2) Linux
Fixed a problem introduced in the previous release where the
Processor and Thermal objects were not recognized and installed in
/proc. This was related to the scope type change described above.
3) iASL Compiler/Disassembler
Implemented the -g option to get all of the required ACPI tables
from the registry and save them to files (Windows version of the
compiler only.) The required tables are the FADT, FACS, and DSDT.
Added ACPI table checksum validation during table disassembly in
order to catch corrupted tables.
----------------------------------------
22 October 2002. Summary of changes for version 20021022.
1) ACPI CA Core Subsystem:
Implemented a restriction on the Scope operator that the target
must already exist in the namespace at the time the operator is
encountered (during table load or method execution). In other
words, forward references are not allowed and Scope() cannot
create a new object. This changes the previous behavior where the
interpreter would create the name if not found. This new behavior
correctly enables the search-to-root algorithm during namespace
lookup of the target name. Because of this upsearch, this fixes
the known Compaq _SB_.OKEC problem and makes both the AML
interpreter and iASL compiler compatible with other ACPI
implementations.
Completed a major overhaul of the internal ACPI object types for
the ACPI Namespace and the associated operand objects. Many of
these types had become obsolete with the introduction of the two-
pass namespace load. This cleanup simplifies the code and makes
the entire namespace load mechanism much clearer and easier to
understand.
Improved debug output for tracking scope opening/closing to help
diagnose scoping issues. The old scope name as well as the new
scope name are displayed. Also improved error messages for
problems with ASL Mutex objects and error messages for GPE
problems.
Cleaned up the namespace dump code, removed obsolete code.
All string output (for all namespace/object dumps) now uses the
common ACPI string output procedure which handles escapes properly
and does not emit non-printable characters.
Fixed some issues with constants in the 64-bit version of the
local C library (utclib.c)
2) Linux
EC Driver: No longer attempts to acquire the Global Lock at
interrupt level.
3) iASL Compiler/Disassembler
Implemented ACPI 2.0B grammar change that disallows all Type 1 and
2 opcodes outside of a control method. This means that the
"executable" operators (versus the "namespace" operators) cannot
be used at the table level; they can only be used within a control
method.
Implemented the restriction on the Scope() operator where the
target must already exist in the namespace at the time the
operator is encountered (during ASL compilation). In other words,
forward references are not allowed and Scope() cannot create a new
object. This makes the iASL compiler compatible with other ACPI
implementations and makes the Scope() implementation adhere to the
ACPI specification.
Fixed a problem where namepath optimization for the Alias operator
was optimizing the wrong path (of the two namepaths.) This caused
a "Missing alias link" error message.
Fixed a problem where an "unknown reserved name" warning could be
incorrectly generated for names like "_SB" when the trailing
underscore is not used in the original ASL.
Fixed a problem where the reserved name check did not handle
NamePaths with multiple NameSegs correctly. The first nameseg of
the NamePath was examined instead of the last NameSeg.
----------------------------------------
02 October 2002. Summary of changes for this release.
1) ACPI CA Core Subsystem version 20021002:
Fixed a problem where a store/copy of a string to an existing
string did not always set the string length properly in the String
object.
Fixed a reported problem with the ToString operator where the
behavior was identical to the ToHexString operator instead of just
simply converting a raw buffer to a string data type.
Fixed a problem where CopyObject and the other "explicit"
conversion operators were not updating the internal namespace node
type as part of the store operation.
Fixed a memory leak during implicit source operand conversion
where the original object was not deleted if it was converted to a
new object of a different type.
Enhanced error messages for all problems associated with namespace
lookups. Common procedure generates and prints the lookup name as
well as the formatted status.
Completed implementation of a new design for the Alias support
within the namespace. The existing design did not handle the case
where a new object was assigned to one of the two names due to the
use of an explicit conversion operator, resulting in the two names
pointing to two different objects. The new design simply points
the Alias name to the original name node - not to the object.
This results in a level of indirection that must be handled in the
name resolution mechanism.
Code and Data Size: Current core subsystem library sizes are shown
below. These are the code and data sizes for the acpica.lib
produced by the Microsoft Visual C++ 6.0 compiler, and these
values do not include any ACPI driver or OSPM code. The debug
version of the code includes the debug output trace mechanism and
has a larger code and data size. Note that these values will vary
depending on the efficiency of the compiler and the compiler
options used during generation.

Brodowski)
3) iASL Compiler/Disassembler
Clarified some warning/error messages.
----------------------------------------
18 September 2002. Summary of changes for this release.
1) ACPI CA Core Subsystem version 20020918:
Fixed a reported problem with reference chaining (via the Index()
and RefOf() operators) in the ObjectType() and SizeOf() operators.
The definition of these operators includes the dereferencing of
all chained references to return information on the base object.
Fixed a problem with stores to indexed package elements - the
existing code would not complete the store if an "implicit
conversion" was not performed. In other words, if the existing
object (package element) was to be replaced completely, the code
didn't handle this case.
Relaxed typechecking on the ASL "Scope" operator to allow the
target name to refer to an object of type Integer, String, or
Buffer, in addition to the scoping object types (Device,
predefined Scopes, Processor, PowerResource, and ThermalZone.)
This allows existing AML code that has workarounds for a bug in
Windows to function properly. A warning is issued, however. This
affects both the AML interpreter and the iASL compiler. Below is
an example of this type of ASL code:
Name(DEB,0x00)
Scope(DEB)
{
Fixed some reported problems with 64-bit integer support in the
local implementation of C library functions (clib.c)
2) Linux
Use ACPI fix map region instead of IOAPIC region, since it is
undefined in non-SMP.
Ensure that the SCI has the proper polarity and trigger, even on
systems that do not have an interrupt override entry in the MADT.
2.5 big driver reorganization (Pat Mochel)
Use early table mapping code from acpitable.c (Andi Kleen)
New blacklist entries (Andi Kleen)
Blacklist improvements. Split blacklist code out into a separate
file. Move checking the blacklist to very early. Previously, we
would use ACPI tables, and then halfway through init, check the
blacklist -- too late. Now, it's early enough to completely fall-
back to non-ACPI.
3) iASL Compiler/Disassembler version 20020918:
Fixed a problem where the typechecking code didn't know that an
alias could point to a method. In other words, aliases were not
being dereferenced during typechecking.
----------------------------------------
29 August 2002. Summary of changes for this release.
1) ACPI CA Core Subsystem Version 20020829:
If the target of a Scope() operator already exists, it must be an
object type that actually opens a scope -- such as a Device,
Method, Scope, etc. This is a fatal runtime error. Similar error
check has been added to the iASL compiler also.
Tightened up the namespace load to disallow multiple names in the
same scope. This previously was allowed if both objects were of
the same type. (i.e., a lookup was the same as entering a new
name).
2) Linux
Ensure that the ACPI interrupt has the proper trigger and
polarity.
local_irq_disable is extraneous. (Matthew Wilcox)
Make "acpi=off" actually do what it says, and not use the ACPI
interpreter *or* the tables.
Added arch-neutral support for parsing SLIT and SRAT tables (Kochi
Takayoshi)
3) iASL Compiler/Disassembler Version 20020829:
Implemented namepath optimization for name declarations. For
example, a declaration like "Method (\_SB_.ABCD)" would get
optimized to "Method (ABCD)" if the declaration is within the
\_SB_ scope. This optimization is in addition to the named
reference path optimization first released in the previous
version. This would seem to complete all possible optimizations
for namepaths within the ASL/AML.
If the target of a Scope() operator already exists, it must be an
object type that actually opens a scope -- such as a Device,
Method, Scope, etc.
Implemented a check and warning for unreachable code in the same
block below a Return() statement.
Fixed a problem where the listing file was not generated if the
compiler aborted if the maximum error count was exceeded (200).
Fixed a problem where the typechecking of method return values was
broken. This includes the check for a return value when the
method is invoked as a TermArg (a return value is expected.)
Fixed a reported problem where EOF conditions during a quoted
string or comment caused a fault.
----------------------------------------
15 August 2002. Summary of changes for this release.
1) ACPI CA Core Subsystem Version 20020815:
Fixed a reported problem where a Store to a method argument that
contains a reference did not perform the indirect store correctly.
This problem was created during the conversion to the new
reference object model - the indirect store to a method argument
code was not updated to reflect the new model.
Reworked the ACPI mode change code to better conform to ACPI 2.0,
handle corner cases, and improve code legibility (Kochi Takayoshi)
Fixed a problem with the pathname parsing for the carat (^)
prefix. The heavy use of the carat operator by the new namepath
optimization in the iASL compiler uncovered a problem with the AML
interpreter handling of this prefix. In the case where one or
more carats precede a single nameseg, the nameseg was treated as
standalone and the search rule (to root) was inadvertently
applied. This could cause both the iASL compiler and the
interpreter to find the wrong object or to miss the error that
should occur if the object does not exist at that exact pathname.
Found and fixed the problem where the HP Pavilion DSDT would not
load. This was a relatively minor tweak to the table loading code
(a problem caused by the unexpected encounter with a method
invocation not within a control method), but it does not solve the
overall issue of the execution of AML code at the table level.
This investigation is still ongoing.
Code and Data Size: Current core subsystem library sizes are shown
below. These are the code and data sizes for the acpica.lib
produced by the Microsoft Visual C++ 6.0 compiler, and these
values do not include any ACPI driver or OSPM code. The debug
version of the code includes the debug output trace mechanism and
has a larger code and data size. Note that these values will vary
depending on the efficiency of the compiler and the compiler
options used during generation.

2) Linux
Remove redundant slab.h include (Brad Hards)
Fix several bugs in thermal.c (Herbert Nachtnebel)
Make CONFIG_ACPI_BOOT work properly (Pavel Machek)
Change acpi_system_suspend to use updated irq functions (Pavel
Machek)
Export acpi_get_firmware_table (Matthew Wilcox)
Use proper root proc entry for ACPI (Kochi Takayoshi)
Fix early-boot table parsing (Bjorn Helgaas)
3) iASL Compiler/Disassembler
Reworked the compiler options to make them more consistent and to
use two-letter options where appropriate. We were running out of
sensible letters. This may break some makefiles, so check the
current options list by invoking the compiler with no parameters.
Completed the design and implementation of the ASL namepath
optimization option for the compiler. This option optimizes all
references to named objects to the shortest possible path. The
first attempt tries to utilize a single nameseg (4 characters) and
the "search-to-root" algorithm used by the interpreter. If that
cannot be used (because either the name is not in the search path
or there is a conflict with another object with the same name),
the pathname is optimized using the carat prefix (usually a
shorter string than specifying the entire path from the root.)
Implemented support to obtain the DSDT from the Windows registry
(when the disassembly option is specified with no input file).
Added this code as the implementation for AcpiOsTableOverride in
the Windows OSL. Migrated the 16-bit code (used in the AcpiDump
utility) to scan memory for the DSDT to the AcpiOsTableOverride
function in the DOS OSL to make the disassembler truly OS
independent.
Implemented a new option to disassemble and compile in one step.
When used without an input filename, this option will grab the
DSDT from the local machine, disassemble it, and compile it in one
step.
Added a warning message for invalid escapes (a backslash followed
by any character other than the allowable escapes). This catches
the quoted string error "\_SB_" (which should be "\\_SB_" ).
Also, there are numerous instances in the ACPI specification where
this error occurs.
Added a compiler option to disable all optimizations. This is
basically the "compatibility mode" because by using this option,
the AML code will come out exactly the same as other ASL
compilers.
Added error messages for incorrectly ordered dependent resource
functions. This includes: missing EndDependentFn macro at end of
dependent resource list, nested dependent function macros (both
start and end), and missing StartDependentFn macro. These are
common errors that should be caught at compile time.
Implemented _OSI support for the disassembler and compiler. _OSI
must be included in the namespace for proper disassembly (because
the disassembler must know the number of arguments.)
Added an "optimization" message type that is optional (off by
default). This message is used for all optimizations - including
constant folding, integer optimization, and namepath optimization.
----------------------------------------
25 July 2002. Summary of changes for this release.
1) ACPI CA Core Subsystem Version 20020725:
The AML Disassembler has been enhanced to produce compilable ASL
code and has been integrated into the iASL compiler (see below) as
well as the single-step disassembly for the AML debugger and the
disassembler for the AcpiDump utility. All ACPI 2.0A opcodes,
resource templates and macros are fully supported. The
disassembler has been tested on over 30 different AML files,
producing identical AML when the resulting disassembled ASL file
is recompiled with the same ASL compiler.
Modified the Resource Manager to allow zero interrupts and zero
dma channels during the GetCurrentResources call. This was
causing problems on some platforms.
Added the AcpiOsRedirectOutput interface to the OSL to simplify
output redirection for the AcpiOsPrintf and AcpiOsVprintf
interfaces.
Code and Data Size: Current core subsystem library sizes are shown
below. These are the code and data sizes for the acpica.lib
produced by the Microsoft Visual C++ 6.0 compiler, and these
values do not include any ACPI driver or OSPM code. The debug
version of the code includes the debug output trace mechanism and
has a larger code and data size. Note that these values will vary
depending on the efficiency of the compiler and the compiler
options used during generation.

2) Linux
Fixed a panic in the EC driver (Dominik Brodowski)
Implemented checksum of the R/XSDT itself during Linux table scan
(Richard Schaal)
3) iASL compiler
The AML disassembler is integrated into the compiler. The "-d"
option invokes the disassembler to completely disassemble an
input AML file, producing as output a text ASL file with the
extension ".dsl" (to avoid name collisions with existing .asl
source files.) A future enhancement will allow the disassembler
to obtain the BIOS DSDT from the registry under Windows.
Fixed a problem with the VendorShort and VendorLong resource
descriptors where an invalid AML sequence was created.
Implemented a fix for BufferData term in the ASL parser. It was
inadvertently defined twice, allowing invalid syntax to pass and
causing reduction conflicts.
Fixed a problem where the Ones opcode could get converted to a
value of zero if "Ones" was used where a byte, word or dword value
was expected. The 64-bit value is now truncated to the correct
size with the correct value.
----------------------------------------
02 July 2002. Summary of changes for this release.
1) ACPI CA Core Subsystem Version 20020702:
The Table Manager code has been restructured to add several new
features. Tables that are not required by the core subsystem
(other than the FADT, DSDT, FACS, PSDTs, etc.) are no longer
validated in any way and are returned from AcpiGetFirmwareTable if
requested. The AcpiOsTableOverride interface is now called for
each table that is loaded by the subsystem in order to allow the
host to override any table it chooses. Previously, only the DSDT
could be overridden. Added one new files, tbrsdt.c and
tbgetall.c.
Fixed a problem with the conversion of internal package objects to
external objects (when a package is returned from a control
method.) The return buffer length was set to zero instead of the
proper length of the package object.
Fixed a reported problem with the use of the RefOf and DeRefOf
operators when passing reference arguments to control methods. A
new type of Reference object is used internally for references
produced by the RefOf operator.
Added additional error messages in the Resource Manager to explain
AE_BAD_DATA errors when they occur during resource parsing.
Split the AcpiEnableSubsystem into two primitives to enable a
finer granularity initialization sequence. These two calls should
be called in this order: AcpiEnableSubsystem (flags),
AcpiInitializeObjects (flags). The flags parameter remains the
same.
2) Linux
Updated the ACPI utilities module to understand the new style of
fully resolved package objects that are now returned from the core
subsystem. This eliminates errors of the form:
ACPI: PCI Interrupt Routing Table [\_SB_.PCI0.PPB_._PRT]
acpi_utils-0430 [145] acpi_evaluate_reference:
Invalid element in package (not a device reference)
The method evaluation utility uses the new buffer allocation
scheme instead of calling AcpiEvaluate Object twice.
Added support for ECDT. This allows the use of the Embedded
Controller before the namespace has been fully initialized, which
is necessary for ACPI 2.0 support, and for some laptops to
initialize properly. (Laptops using ECDT are still rare, so only
limited testing was performed of the added functionality.)
Fixed memory leaks in the EC driver.
Eliminated a brittle code structure in acpi_bus_init().
Eliminated the acpi_evaluate() helper function in utils.c. It is
no longer needed since acpi_evaluate_object can optionally
allocate memory for the return object.
Implemented fix for keyboard hang when getting battery readings on
some systems (Stephen White)
PCI IRQ routing update (Dominik Brodowski)
Fix an ifdef to allow compilation on UP with LAPIC but no IOAPIC
support
----------------------------------------
11 June 2002. Summary of changes for this release.
1) ACPI CA Core Subsystem Version 20020611:
Fixed a reported problem where constants such as Zero and One
appearing within _PRT packages were not handled correctly within
the resource manager code. Originally reported against the ASL
compiler because the code generator now optimizes integers to
their minimal AML representation (i.e. AML constants if possible.)
The _PRT code now handles all AML constant opcodes correctly
(Zero, One, Ones, Revision).
Fixed a problem with the Concatenate operator in the AML
interpreter where a buffer result object was incorrectly marked as
not fully evaluated, causing a run-time error of AE_AML_INTERNAL.
All package sub-objects are now fully resolved before they are
returned from the external ACPI interfaces. This means that name
strings are resolved to object handles, and constant operators
(Zero, One, Ones, Revision) are resolved to Integers.
Implemented immediate resolution of the AML Constant opcodes
(Zero, One, Ones, Revision) to Integer objects upon detection
within the AML stream. This has simplified and reduced the
generated code size of the subsystem by eliminating about 10
switch statements for these constants (which previously were
contained in Reference objects.) The complicating issues are that
the Zero opcode is used as a "placeholder" for unspecified
optional target operands and stores to constants are defined to be
no-ops.
Code and Data Size: Current core subsystem library sizes are shown
below. These are the code and data sizes for the acpica.lib
produced by the Microsoft Visual C++ 6.0 compiler, and these
values do not include any ACPI driver or OSPM code. The debug
version of the code includes the debug output trace mechanism and
has a larger code and data size. Note that these values will vary
depending on the efficiency of the compiler and the compiler
options used during generation.

2) Linux
Added preliminary support for obtaining _TRA data for PCI root
bridges (Bjorn Helgaas).
3) iASL Compiler Version X2046:
Fixed a problem where the "_DDN" reserved name was defined to be a
control method with one argument. There are no arguments, and
_DDN does not have to be a control method.
Fixed a problem with the Linux version of the compiler where the
source lines printed with error messages were the wrong lines.
This turned out to be the "LF versus CR/LF" difference between
Windows and Unix. This appears to be the longstanding issue
concerning listing output and error messages.
Fixed a problem with the Linux version of compiler where opcode
names within error messages were wrong. This was caused by a
slight difference in the output of the Flex tool on Linux versus
Windows.
Fixed a problem with the Linux compiler where the hex output files
contained some garbage data caused by an internal buffer overrun.
----------------------------------------
17 May 2002. Summary of changes for this release.
1) ACPI CA Core Subsystem Version 20020517:
Implemented a workaround to an BIOS bug discovered on the HP
OmniBook where the FADT revision number and the table size are
inconsistent (ACPI 2.0 revision vs. ACPI 1.0 table size). The new
behavior is to fallback to using only the ACPI 1.0 fields of the
FADT if the table is too small to be a ACPI 2.0 table as claimed
by the revision number. Although this is a BIOS bug, this is a
case where the workaround is simple enough and with no side
effects, so it seemed prudent to add it. A warning message is
issued, however.
Implemented minimum size checks for the fixed-length ACPI tables -
- the FADT and FACS, as well as consistency checks between the
revision number and the table size.
Fixed a reported problem in the table override support where the
new table pointer was incorrectly treated as a physical address
instead of a logical address.
Eliminated the use of the AE_AML_ERROR exception and replaced it
with more descriptive codes.
Fixed a problem where an exception would occur if an ASL Field was
defined with no named Field Units underneath it (used by some
index fields).
Code and Data Size: Current core subsystem library sizes are shown
below. These are the code and data sizes for the acpica.lib
produced by the Microsoft Visual C++ 6.0 compiler, and these
values do not include any ACPI driver or OSPM code. The debug
version of the code includes the debug output trace mechanism and
has a larger code and data size. Note that these values will vary
depending on the efficiency of the compiler and the compiler
options used during generation.

Fix "MHz" typo (Dominik Brodowski)
Fix RTC year 2000 issue (Dominik Brodowski)
Preclude multiple button proc entries (Eric Brunet)
Moved arch-specific code out of include/platform/aclinux.h
3) iASL Compiler Version X2044:
Implemented error checking for the string used in the EISAID macro
(Usually used in the definition of the _HID object.) The code now
strictly enforces the PnP format - exactly 7 characters, 3
uppercase letters and 4 hex digits.
If a raw string is used in the definition of the _HID object
(instead of the EISAID macro), the string must contain all
alphanumeric characters (e.g., "*PNP0011" is not allowed because
of the asterisk.)
Implemented checking for invalid use of ACPI reserved names for
most of the name creation operators (Name, Device, Event, Mutex,
OperationRegion, PowerResource, Processor, and ThermalZone.)
Previously, this check was only performed for control methods.
Implemented an additional check on the Name operator to emit an
error if a reserved name that must be implemented in ASL as a
control method is used. We know that a reserved name must be a
method if it is defined with input arguments.
The warning emitted when a namespace object reference is not found
during the cross reference phase has been changed into an error.
The "External" directive should be used for names defined in other
modules.
4) Tools and Utilities
The 16-bit tools (adump16 and aexec16) have been regenerated and
tested.
Fixed a problem with the output of both acpidump and adump16 where
the indentation of closing parentheses and brackets was not
aligned properly with the parent block.
----------------------------------------
03 May 2002. Summary of changes for this release.
1) ACPI CA Core Subsystem Version 20020503:
Added support a new OSL interface that allows the host operating
system software to override the DSDT found in the firmware -
AcpiOsTableOverride. With this interface, the OSL can examine the
version of the firmware DSDT and replace it with a different one
if desired.
Added new external interfaces for accessing ACPI registers from
device drivers and other system software - AcpiGetRegister and
AcpiSetRegister. This was simply an externalization of the
existing AcpiHwBitRegister interfaces.
Fixed a regression introduced in the previous build where the
ASL/AML CreateField operator always returned an error,
"destination must be a NS Node".
Extended the maximum time (before failure) to successfully enable
ACPI mode to 3 seconds.
Code and Data Size: Current core subsystem library sizes are shown
below. These are the code and data sizes for the acpica.lib
produced by the Microsoft Visual C++ 6.0 compiler, and these
values do not include any ACPI driver or OSPM code. The debug
version of the code includes the debug output trace mechanism and
has a larger code and data size. Note that these values will vary
depending on the efficiency of the compiler and the compiler
options used during generation.

Debug Version: 142.9K Code, 58.4K Data, 201.3K Total
2) Linux
Enhanced ACPI init code for SMP. We are now fully MPS and $PIR-
free. While 3 out of 4 of our in-house systems work fine, the last
one still hangs when testing the LAPIC timer.
Renamed many files in 2.5 kernel release to omit "acpi_" from the
name.
Added warning on boot for Presario 711FR.
Sleep improvements (Pavel Machek)
ACPI can now be built without CONFIG_PCI enabled.
IA64: Fixed memory map functions (JI Lee)
3) iASL Compiler Version X2043:
Added support to allow the compiler to be integrated into the MS
VC++ development environment for one-button compilation of single
files or entire projects -- with error-to-source-line mapping.
Implemented support for compile-time constant folding for the
Type3, Type4, and Type5 opcodes first defined in the ACPI 2.0
specification. This allows the ASL writer to use expressions
instead of Integer/Buffer/String constants in terms that must
evaluate to constants at compile time and will also simplify the
emitted AML in any such sub-expressions that can be folded
(evaluated at compile-time.) This increases the size of the
compiler significantly because a portion of the ACPI CA AML
interpreter is included within the compiler in order to pre-
evaluate constant expressions.
Fixed a problem with the "Unicode" ASL macro that caused the
compiler to fault. (This macro is used in conjunction with the
_STR reserved name.)
Implemented an AML opcode optimization to use the Zero, One, and
Ones opcodes where possible to further reduce the size of integer
constants and thus reduce the overall size of the generated AML
code.
Implemented error checking for new reserved terms for ACPI version
2.0A.
Implemented the -qr option to display the current list of ACPI
reserved names known to the compiler.
Implemented the -qc option to display the current list of ASL
operators that are allowed within constant expressions and can
therefore be folded at compile time if the operands are constants.
4) Documentation
Updated the Programmer's Reference for new interfaces, data types,
and memory allocation model options.
Updated the iASL Compiler User Reference to apply new format and
add information about new features and options.
----------------------------------------
19 April 2002. Summary of changes for this release.
1) ACPI CA Core Subsystem Version 20020419:
The source code base for the Core Subsystem has been completely
cleaned with PC-lint (FlexLint) for both 32-bit and 64-bit
versions. The Lint option files used are included in the
/acpi/generate/lint directory.
Implemented enhanced status/error checking across the entire
Hardware manager subsystem. Any hardware errors (reported from
the OSL) are now bubbled up and will abort a running control
method.
Fixed a problem where the per-ACPI-table integer width (32 or 64)
was stored only with control method nodes, causing a fault when
non-control method code was executed during table loading. The
solution implemented uses a global variable to indicate table
width across the entire ACPI subsystem. Therefore, ACPI CA does
not support mixed integer widths across different ACPI tables
(DSDT, SSDT).
Fixed a problem where NULL extended fields (X fields) in an ACPI
2.0 ACPI FADT caused the table load to fail. Although the
existing ACPI specification is a bit fuzzy on this topic, the new
behavior is to fall back on a ACPI 1.0 field if the corresponding
ACPI 2.0 X field is zero (even though the table revision indicates
a full ACPI 2.0 table.) The ACPI specification will be updated to
clarify this issue.
Fixed a problem with the SystemMemory operation region handler
where memory was always accessed byte-wise even if the AML-
specified access width was larger than a byte. This caused
problems on systems with memory-mapped I/O. Memory is now
accessed with the width specified. On systems that do not support
non-aligned transfers, a check is made to guarantee proper address
alignment before proceeding in order to avoid an AML-caused
alignment fault within the kernel.
Fixed a problem with the ExtendedIrq resource where only one byte
of the 4-byte Irq field was extracted.
Fixed the AcpiExDigitsNeeded() procedure to support _UID. This
function was out of date and required a rewrite.
Code and Data Size: Current core subsystem library sizes are shown
below. These are the code and data sizes for the acpica.lib
produced by the Microsoft Visual C++ 6.0 compiler, and these
values do not include any ACPI driver or OSPM code. The debug
version of the code includes the debug output trace mechanism and
has a larger code and data size. Note that these values will vary
depending on the efficiency of the compiler and the compiler
options used during generation.

2) Linux
PCI IRQ routing fixes (Dominik Brodowski)
3) iASL Compiler Version X2042:
Implemented an additional compile-time error check for a field
unit whose size + minimum access width would cause a run-time
access beyond the end-of-region. Previously, only the field size
itself was checked.
The Core subsystem and iASL compiler now share a common parse
object in preparation for compile-time evaluation of the type
3/4/5 ASL operators.
----------------------------------------
Summary of changes for this release: 03_29_02
1) ACPI CA Core Subsystem Version 20020329:
Implemented support for late evaluation of TermArg operands to
Buffer and Package objects. This allows complex expressions to be
used in the declarations of these object types.
Fixed an ACPI 1.0 compatibility issue when reading Fields. In ACPI
1.0, if the field was larger than 32 bits, it was returned as a
buffer - otherwise it was returned as an integer. In ACPI 2.0,
the field is returned as a buffer only if the field is larger than
64 bits. The TableRevision is now considered when making this
conversion to avoid incompatibility with existing ASL code.
Implemented logical addressing for AcpiOsGetRootPointer. This
allows an RSDP with either a logical or physical address. With
this support, the host OS can now override all ACPI tables with
one logical RSDP. Includes implementation of "typed" pointer
support to allow a common data type for both physical and logical
pointers internally. This required a change to the
AcpiOsGetRootPointer interface.
Implemented the use of ACPI 2.0 Generic Address Structures for all
GPE, Fixed Event, and PM Timer I/O. This allows the use of memory
mapped I/O for these ACPI features.
Initialization now ignores not only non-required tables (All
tables other than the FADT, FACS, DSDT, and SSDTs), but also does
not validate the table headers of unrecognized tables.
Fixed a problem where a notify handler could only be
installed/removed on an object of type Device. All "notify"
objects are now supported -- Devices, Processor, Power, and
Thermal.
Removed most verbosity from the ACPI_DB_INFO debug level. Only
critical information is returned when this debug level is enabled.
Code and Data Size: Current core subsystem library sizes are shown
below. These are the code and data sizes for the acpica.lib
produced by the Microsoft Visual C++ 6.0 compiler, and these
values do not include any ACPI driver or OSPM code. The debug
version of the code includes the debug output trace mechanism and
has a larger code and data size. Note that these values will vary
depending on the efficiency of the compiler and the compiler
options used during generation.

Debug Version: 138.0K Code, 56.6K Data, 194.6K Total
Current Release:
Non-Debug Version: 66.6K Code, 6.5K Data, 73.1K Total
Debug Version: 139.8K Code, 57.4K Data, 197.2K Total
2) Linux:
The processor driver (acpi_processor.c) now fully supports ACPI
2.0-based processor performance control (e.g. Intel(R)
SpeedStep(TM) technology) Note that older laptops that only have
the Intel "applet" interface are not supported through this. The
'limit' and 'performance' interface (/proc) are fully functional.
[Note that basic policy for controlling performance state
transitions will be included in the next version of ospmd.] The
idle handler was modified to more aggressively use C2, and PIIX4
errata handling underwent a complete overhaul (big thanks to
Dominik Brodowski).
Added support for ACPI-PCI device binding (acpi_pci_root.c). _ADR-
based devices in the ACPI namespace are now dynamically bound
(associated) with their PCI counterparts (e.g. PCI1->01:00.0).
This allows, among other things, ACPI to resolve bus numbers for
subordinate PCI bridges.
Enhanced PCI IRQ routing to get the proper bus number for _PRT
entries defined underneath PCI bridges.
Added IBM 600E to bad bios list due to invalid _ADR value for
PIIX4 PCI-ISA bridge, resulting in improper PCI IRQ routing.
In the process of adding full MADT support (e.g. IOAPIC) for IA32
(acpi.c, mpparse.c) -- stay tuned.
Added back visual differentiation between fixed-feature and
control-method buttons in dmesg. Buttons are also subtyped (e.g.
button/power/PWRF) to simplify button identification.
We no longer use -Wno-unused when compiling debug. Please ignore
any "_THIS_MODULE defined but not used" messages.
Can now shut down the system using "magic sysrq" key.
3) iASL Compiler version 2041:
Fixed a problem where conversion errors for hex/octal/decimal
constants were not reported.
Implemented a fix for the General Register template Address field.
This field was 8 bits when it should be 64.
Fixed a problem where errors/warnings were no longer being emitted
within the listing output file.
Implemented the ACPI 2.0A restriction on ACPI Table Signatures to
exactly 4 characters, alphanumeric only.
----------------------------------------
Summary of changes for this release: 03_08_02
1) ACPI CA Core Subsystem Version 20020308:
Fixed a problem with AML Fields where the use of the "AccessAny"
keyword could cause an interpreter error due to attempting to read
or write beyond the end of the parent Operation Region.
Fixed a problem in the SystemMemory Operation Region handler where
an attempt was made to map memory beyond the end of the region.
This was the root cause of the "AE_ERROR" and "AE_NO_MEMORY"
errors on some Linux systems.
Fixed a problem where the interpreter/namespace "search to root"
algorithm was not functioning for some object types. Relaxed the
internal restriction on the search to allow upsearches for all
external object types as well as most internal types.
2) Linux:
We now use safe_halt() macro versus individual calls to sti | hlt.
Writing to the processor limit interface should now work. "echo 1"
will increase the limit, 2 will decrease, and 0 will reset to the
default.
3) ASL compiler:
Fixed segfault on Linux version.
----------------------------------------
Summary of changes for this release: 02_25_02
1) ACPI CA Core Subsystem:
Fixed a problem where the GPE bit masks were not initialized
properly, causing erratic GPE behavior.
Implemented limited support for multiple calling conventions. The
code can be generated with either the VPL (variable parameter
list, or "C") convention, or the FPL (fixed parameter list, or
"Pascal") convention. The core subsystem is about 3.4% smaller
when generated with FPL.
2) Linux
Re-add some /proc/acpi/event functionality that was lost during
the rewrite
Resolved issue with /proc events for fixed-feature buttons showing
up as the system device.
Fixed checks on C2/C3 latencies to be inclusive of maximum values.
Replaced AE_ERRORs in acpi_osl.c with more specific error codes.
Changed ACPI PRT option from "pci=noacpi-routing" to "pci=noacpi"
Fixed limit interface & usage to fix bugs with passive cooling
hysterisis.
Restructured PRT support.
----------------------------------------
Summary of changes for this label: 02_14_02
1) ACPI CA Core Subsystem:
Implemented support in AcpiLoadTable to allow loading of FACS and
FADT tables.
Suport for the now-obsolete interim 0.71 64-bit ACPI tables has
been removed. All 64-bit platforms should be migrated to the ACPI
2.0 tables. The actbl71.h header has been removed from the source
tree.
All C macros defined within the subsystem have been prefixed with
"ACPI_" to avoid collision with other system include files.
Removed the return value for the two AcpiOsPrint interfaces, since
it is never used and causes lint warnings for ignoring the return
value.
Added error checking to all internal mutex acquire and release
calls. Although a failure from one of these interfaces is
probably a fatal system error, these checks will cause the
immediate abort of the currently executing method or interface.
Fixed a problem where the AcpiSetCurrentResources interface could
fault. This was a side effect of the deployment of the new memory
allocation model.
Fixed a couple of problems with the Global Lock support introduced
in the last major build. The "common" (1.0/2.0) internal FACS was
being overwritten with the FACS signature and clobbering the
Global Lock pointer. Also, the actual firmware FACS was being
unmapped after construction of the "common" FACS, preventing
access to the actual Global Lock field within it. The "common"
internal FACS is no longer installed as an actual ACPI table; it
is used simply as a global.
Code and Data Size: Current core subsystem library sizes are shown
below. These are the code and data sizes for the acpica.lib
produced by the Microsoft Visual C++ 6.0 compiler, and these
values do not include any ACPI driver or OSPM code. The debug
version of the code includes the debug output trace mechanism and
has a larger code and data size. Note that these values will vary
depending on the efficiency of the compiler and the compiler
options used during generation.

2) Linux
Updated Linux-specific code for core macro and OSL interface
changes described above.
Improved /proc/acpi/event. It now can be opened only once and has
proper poll functionality.
Fixed and restructured power management (acpi_bus).
Only create /proc "view by type" when devices of that class exist.
Fixed "charging/discharging" bug (and others) in acpi_battery.
Improved thermal zone code.
3) ASL Compiler, version X2039:
Implemented the new compiler restriction on ASL String hex/octal
escapes to non-null, ASCII values. An error results if an invalid
value is used. (This will require an ACPI 2.0 specification
change.)
AML object labels that are output to the optional C and ASM source
are now prefixed with both the ACPI table signature and table ID
to help guarantee uniqueness within a large BIOS project.
----------------------------------------
Summary of changes for this label: 02_01_02
1) ACPI CA Core Subsystem:
ACPI 2.0 support is complete in the entire Core Subsystem and the
ASL compiler. All new ACPI 2.0 operators are implemented and all
other changes for ACPI 2.0 support are complete. With
simultaneous code and data optimizations throughout the subsystem,
ACPI 2.0 support has been implemented with almost no additional
cost in terms of code and data size.
Implemented a new mechanism for allocation of return buffers. If
the buffer length is set to ACPI_ALLOCATE_BUFFER, the buffer will
be allocated on behalf of the caller. Consolidated all return
buffer validation and allocation to a common procedure. Return
buffers will be allocated via the primary OSL allocation interface
since it appears that a separate pool is not needed by most users.
If a separate pool is required for these buffers, the caller can
still use the original mechanism and pre-allocate the buffer(s).
Implemented support for string operands within the DerefOf
operator.
Restructured the Hardware and Event managers to be table driven,
simplifying the source code and reducing the amount of generated
code.
Split the common read/write low-level ACPI register bitfield
procedure into a separate read and write, simplifying the code
considerably.
Obsoleted the AcpiOsCallocate OSL interface. This interface was
used only a handful of times and didn't have enough critical mass
for a separate interface. Replaced with a common calloc procedure
in the core.
Fixed a reported problem with the GPE number mapping mechanism
that allows GPE1 numbers to be non-contiguous with GPE0.
Reorganized the GPE information and shrunk a large array that was
originally large enough to hold info for all possible GPEs (256)
to simply large enough to hold all GPEs up to the largest GPE
number on the machine.
Fixed a reported problem with resource structure alignment on 64-
bit platforms.
Changed the AcpiEnableEvent and AcpiDisableEvent external
interfaces to not require any flags for the common case of
enabling/disabling a GPE.
Implemented support to allow a "Notify" on a Processor object.
Most TBDs in comments within the source code have been resolved
and eliminated.
Fixed a problem in the interpreter where a standalone parent
prefix (^) was not handled correctly in the interpreter and
debugger.
Removed obsolete and unnecessary GPE save/restore code.
Implemented Field support in the ASL Load operator. This allows a
table to be loaded from a named field, in addition to loading a
table directly from an Operation Region.
Implemented timeout and handle support in the external Global Lock
interfaces.
Fixed a problem in the AcpiDump utility where pathnames were no
longer being generated correctly during the dump of named objects.
Modified the AML debugger to give a full display of if/while
predicates instead of just one AML opcode at a time. (The
predicate can have several nested ASL statements.) The old method
was confusing during single stepping.
Code and Data Size: Current core subsystem library sizes are shown
below. These are the code and data sizes for the acpica.lib
produced by the Microsoft Visual C++ 6.0 compiler, and these
values do not include any ACPI driver or OSPM code. The debug
version of the code includes the debug output trace mechanism and
has a larger code and data size. Note that these values will vary
depending on the efficiency of the compiler and the compiler
options used during generation.

2) Linux
Implemented fix for PIIX reverse throttling errata (Processor
driver)
Added new Limit interface (Processor and Thermal drivers)
New thermal policy (Thermal driver)
Many updates to /proc
Battery "low" event support (Battery driver)
Supports ACPI PCI IRQ routing (PCI Link and PCI root drivers)
IA32 - IA64 initialization unification, no longer experimental
Menuconfig options redesigned
3) ASL Compiler, version X2037:
Implemented several new output features to simplify integration of
AML code into firmware: 1) Output the AML in C source code with
labels for each named ASL object. The original ASL source code
is interleaved as C comments. 2) Output the AML in ASM source code
with labels and interleaved ASL source. 3) Output the AML in
raw hex table form, in either C or ASM.
Implemented support for optional string parameters to the
LoadTable operator.
Completed support for embedded escape sequences within string
literals. The compiler now supports all single character escapes
as well as the Octal and Hex escapes. Note: the insertion of a
null byte into a string literal (via the hex/octal escape) causes
the string to be immediately terminated. A warning is issued.
Fixed a problem where incorrect AML was generated for the case
where an ASL namepath consists of a single parent prefix (
) with no trailing name segments.
The compiler has been successfully generated with a 64-bit C
compiler.
----------------------------------------
Summary of changes for this label: 12_18_01
1) Linux
Enhanced blacklist with reason and severity fields. Any table's
signature may now be used to identify a blacklisted system.
Call _PIC control method to inform the firmware which interrupt
model the OS is using. Turn on any disabled link devices.
Cleaned up busmgr /proc error handling (Andreas Dilger)
2) ACPI CA Core Subsystem:
Implemented ACPI 2.0 semantics for the "Break" operator (Exit from
while loop)
Completed implementation of the ACPI 2.0 "Continue",
"ConcatenateResTemplate", "DataTableRegion", and "LoadTable"
operators. All new ACPI 2.0 operators are now implemented in both
the ASL compiler and the AML interpreter. The only remaining ACPI
2.0 task is support for the String data type in the DerefOf
operator. Fixed a problem with AcquireMutex where the status code
was lost if the caller had to actually wait for the mutex.
Increased the maximum ASL Field size from 64K bits to 4G bits.
Completed implementation of the external Global Lock interfaces --
AcpiAcquireGlobalLock and AcpiReleaseGlobalLock. The Timeout and
Handler parameters were added.
Completed another pass at removing warnings and issues when
compiling with 64-bit compilers. The code now compiles cleanly
with the Intel 64-bit C/C++ compiler. Most notably, the pointer
add and subtract (diff) macros have changed considerably.
Created and deployed a new ACPI_SIZE type that is 64-bits wide on
64-bit platforms, 32-bits on all others. This type is used
wherever memory allocation and/or the C sizeof() operator is used,
and affects the OSL memory allocation interfaces AcpiOsAllocate
and AcpiOsCallocate.
Implemented sticky user breakpoints in the AML debugger.
Code and Data Size: Current core subsystem library sizes are shown
below. These are the code and data sizes for the acpica.lib
produced by the Microsoft Visual C++ 6.0 compiler, and these
values do not include any ACPI driver or OSPM code. The debug
version of the code includes the debug output trace mechanism and
has a larger code and data size. Note that these values will vary
depending on the efficiency of the compiler and the compiler
options used during generation.

Now checks for (and generates an error if detected) the use of a
Break or Continue statement without an enclosing While statement.
Successfully generated the compiler with the Intel 64-bit C
compiler.
----------------------------------------
Summary of changes for this label: 12_05_01
1) ACPI CA Core Subsystem:
The ACPI 2.0 CopyObject operator is fully implemented. This
operator creates a new copy of an object (and is also used to
bypass the "implicit conversion" mechanism of the Store operator.)
The ACPI 2.0 semantics for the SizeOf operator are fully
implemented. The change is that performing a SizeOf on a
reference object causes an automatic dereference of the object to
tha actual value before the size is evaluated. This behavior was
undefined in ACPI 1.0.
The ACPI 2.0 semantics for the Extended IRQ resource descriptor
have been implemented. The interrupt polarity and mode are now
independently set.
Fixed a problem where ASL Constants (Zero, One, Ones, Revision)
appearing in Package objects were not properly converted to
integers when the internal Package was converted to an external
object (via the AcpiEvaluateObject interface.)
Fixed a problem with the namespace object deletion mechanism for
objects created by control methods. There were two parts to this
problem: 1) Objects created during the initialization phase method
parse were not being deleted, and 2) The object owner ID mechanism
to track objects was broken.
Fixed a problem where the use of the ASL Scope operator within a
control method would result in an invalid opcode exception.
Fixed a problem introduced in the previous label where the buffer
length required for the _PRT structure was not being returned
correctly.
Code and Data Size: Current core subsystem library sizes are shown
below. These are the code and data sizes for the acpica.lib
produced by the Microsoft Visual C++ 6.0 compiler, and these
values do not include any ACPI driver or OSPM code. The debug
version of the code includes the debug output trace mechanism and
has a larger code and data size. Note that these values will vary
depending on the efficiency of the compiler and the compiler
options used during generation.

Debug Version: 136.2K Code, 55.6K Data, 191.8K Total
2) Linux:
Updated all files to apply cleanly against 2.4.16.
Added basic PCI Interrupt Routing Table (PRT) support for IA32
(acpi_pci.c), and unified the PRT code for IA32 and IA64. This
version supports both static and dyanmic PRT entries, but dynamic
entries are treated as if they were static (not yet
reconfigurable). Architecture- specific code to use this data is
absent on IA32 but should be available shortly.
Changed the initialization sequence to start the ACPI interpreter
(acpi_init) prior to initialization of the PCI driver (pci_init)
in init/main.c. This ordering is required to support PRT and
facilitate other (future) enhancement. A side effect is that the
ACPI bus driver and certain device drivers can no longer be loaded
as modules.
Modified the 'make menuconfig' options to allow PCI Interrupt
Routing support to be included without the ACPI Bus and other
device drivers.
3) ASL Compiler, version X2033:
Fixed some issues with the use of the new CopyObject and
DataTableRegion operators. Both are fully functional.
----------------------------------------
Summary of changes for this label: 11_20_01
20 November 2001. Summary of changes for this release.
1) ACPI CA Core Subsystem:
Updated Index support to match ACPI 2.0 semantics. Storing a
Integer, String, or Buffer to an Index of a Buffer will store only
the least-significant byte of the source to the Indexed buffer
byte. Multiple writes are not performed.
Fixed a problem where the access type used in an AccessAs ASL
operator was not recorded correctly into the field object.
Fixed a problem where ASL Event objects were created in a
signalled state. Events are now created in an unsignalled state.
The internal object cache is now purged after table loading and
initialization to reduce the use of dynamic kernel memory -- on
the assumption that object use is greatest during the parse phase
of the entire table (versus the run-time use of individual control
methods.)
ACPI 2.0 variable-length packages are now fully operational.
Code and Data Size: Code and Data optimizations have permitted new
feature development with an actual reduction in the library size.
Current core subsystem library sizes are shown below. These are
the code and data sizes for the acpica.lib produced by the
Microsoft Visual C++ 6.0 compiler, and these values do not include
any ACPI driver or OSPM code. The debug version of the code
includes the debug output trace mechanism and has a larger code
and data size. Note that these values will vary depending on the
efficiency of the compiler and the compiler options used during
generation.

2) Linux:
Enhanced the ACPI boot-time initialization code to allow the use
of Local APIC tables for processor enumeration on IA-32, and to
pave the way for a fully MPS-free boot (on SMP systems) in the
near future. This functionality replaces
arch/i386/kernel/acpitables.c, which was introduced in an earlier
2.4.15-preX release. To enable this feature you must add
"acpi_boot=on" to the kernel command line -- see the help entry
for CONFIG_ACPI_BOOT for more information. An IA-64 release is in
the works...
Restructured the configuration options to allow boot-time table
parsing support without inclusion of the ACPI Interpreter (and
other) code.
NOTE: This release does not include fixes for the reported events,
power-down, and thermal passive cooling issues (coming soon).
3) ASL Compiler:
Added additional typechecking for Fields within restricted access
Operation Regions. All fields within EC and CMOS regions must be
declared with ByteAcc. All fields withing SMBus regions must be
declared with the BufferAcc access type.
Fixed a problem where the listing file output of control methods
no longer interleaved the actual AML code with the ASL source
code.
----------------------------------------
Summary of changes for this label: 11_09_01
1) ACPI CA Core Subsystem:
Implemented ACPI 2.0-defined support for writes to fields with a
Buffer, String, or Integer source operand that is smaller than the
target field. In these cases, the source operand is zero-extended
to fill the target field.
Fixed a problem where a Field starting bit offset (within the
parent operation region) was calculated incorrectly if the
alignment of the field differed from the access width. This
affected CreateWordField, CreateDwordField, CreateQwordField, and
possibly other fields that use the "AccessAny" keyword.
Fixed a problem introduced in the 11_02_01 release where indirect
stores through method arguments did not operate correctly.
2) Linux:
Implemented boot-time ACPI table parsing support
(CONFIG_ACPI_BOOT) for IA32 and IA64 UP/SMP systems. This code
facilitates the use of ACPI tables (e.g. MADT, SRAT) rather than
legacy BIOS interfaces (e.g. MPS) for the configuration of system
processors, memory, and interrupts during setup_arch(). Note that
this patch does not include the required architecture-specific
changes required to apply this information -- subsequent patches
will be posted for both IA32 and IA64 to achieve this.
Added low-level sleep support for IA32 platforms, courtesy of Pat
Mochel. This allows IA32 systems to transition to/from various
sleeping states (e.g. S1, S3), although the lack of a centralized
driver model and power-manageable drivers will prevent its
(successful) use on most systems.
Revamped the ACPI 'menuconfig' layout: created new "ACPI Support"
submenu, unified IA32 and IA64 options, added new "Boot using ACPI
tables" option, etc.
Increased the default timeout for the EC driver from 1ms to 10ms
(1000 cycles of 10us) to try to address AE_TIME errors during EC
transactions.
----------------------------------------
Summary of changes for this label: 11_02_01
1) ACPI CA Core Subsystem:
ACPI 2.0 Support: Implemented ACPI 2.0 64-bit Field access
(QWordAcc keyword). All ACPI 2.0 64-bit support is now
implemented.
OSL Interfaces: Several of the OSL (AcpiOs*) interfaces required
changes to support ACPI 2.0 Qword field access. Read/Write
PciConfiguration(), Read/Write Memory(), and Read/Write Port() now
accept an ACPI_INTEGER (64 bits) as the value parameter. Also,
the value parameter for the address space handler interface is now
an ACPI_INTEGER. OSL implementations of these interfaces must now
handle the case where the Width parameter is 64.
Index Fields: Fixed a problem where unaligned bit assembly and
disassembly for IndexFields was not supported correctly.
Index and Bank Fields: Nested Index and Bank Fields are now
supported. During field access, a check is performed to ensure
that the value written to an Index or Bank register is not out of
the range of the register. The Index (or Bank) register is
written before each access to the field data. Future support will
include allowing individual IndexFields to be wider than the
DataRegister width.
Fields: Fixed a problem where the AML interpreter was incorrectly
attempting to write beyond the end of a Field/OpRegion. This was
a boundary case that occurred when a DWORD field was written to a
BYTE access OpRegion, forcing multiple writes and causing the
interpreter to write one datum too many.
Fields: Fixed a problem with Field/OpRegion access where the
starting bit address of a field was incorrectly calculated if the
current access type was wider than a byte (WordAcc, DwordAcc, or
QwordAcc).
Fields: Fixed a problem where forward references to individual
FieldUnits (individual Field names within a Field definition) were
not resolved during the AML table load.
Fields: Fixed a problem where forward references from a Field
definition to the parent Operation Region definition were not
resolved during the AML table load.
Fields: Duplicate FieldUnit names within a scope are now detected
during AML table load.
Acpi Interfaces: Fixed a problem where the AcpiGetName() interface
returned an incorrect name for the root node.
Code and Data Size: Code and Data optimizations have permitted new
feature development with an actual reduction in the library size.
Current core subsystem library sizes are shown below. These are
the code and data sizes for the acpica.lib produced by the
Microsoft Visual C++ 6.0 compiler, and these values do not include
any ACPI driver or OSPM code. The debug version of the code
includes the debug output trace mechanism and has a larger code
and data size. Note that these values will vary depending on the
efficiency of the compiler and the compiler options used during
generation.

handler interface changes described above.
----------------------------------------
Summary of changes for this label: 10_18_01
ACPI CA Core Subsystem:
Fixed a problem with the internal object reference count mechanism
that occasionally caused premature object deletion. This resolves
all of the outstanding problem reports where an object is deleted
in the middle of an interpreter evaluation. Although this problem
only showed up in rather obscure cases, the solution to the
problem involved an adjustment of all reference counts involving
objects attached to namespace nodes.
Fixed a problem with Field support in the interpreter where
writing to an aligned field whose length is an exact multiple (2
or greater) of the field access granularity would cause an attempt
to write beyond the end of the field.
The top level AML opcode execution functions within the
interpreter have been renamed with a more meaningful and
consistent naming convention. The modules exmonad.c and
exdyadic.c were eliminated. New modules are exoparg1.c,
exoparg2.c, exoparg3.c, and exoparg6.c.
Support for the ACPI 2.0 "Mid" ASL operator has been implemented.
Fixed a problem where the AML debugger was causing some internal
objects to not be deleted during subsystem termination.
Fixed a problem with the external AcpiEvaluateObject interface
where the subsystem would fault if the named object to be
evaluated refered to a constant such as Zero, Ones, etc.
Fixed a problem with IndexFields and BankFields where the
subsystem would fault if the index, data, or bank registers were
not defined in the same scope as the field itself.
Added printf format string checking for compilers that support
this feature. Corrected more than 50 instances of issues with
format specifiers within invocations of ACPI_DEBUG_PRINT
throughout the core subsystem code.
The ASL "Revision" operator now returns the ACPI support level
implemented in the core - the value "2" since the ACPI 2.0 support
is more than 50% implemented.
Enhanced the output of the AML debugger "dump namespace" command
to output in a more human-readable form.
Current core subsystem library code sizes are shown below. These
are the code and data sizes for the acpica.lib produced by the
Microsoft Visual C++ 6.0 compiler, and these values do not include
any ACPI driver or OSPM code. The debug version of the code
includes the full debug trace mechanism -- leading to a much
larger code and data size. Note that these values will vary
depending on the efficiency of the compiler and the compiler
options used during generation.

Linux:
Implemented a "Bad BIOS Blacklist" to track machines that have
known ASL/AML problems.
Enhanced the /proc interface for the thermal zone driver and added
support for _HOT (the critical suspend trip point). The 'info'
file now includes threshold/policy information, and allows setting
of _SCP (cooling preference) and _TZP (polling frequency) values
to the 'info' file. Examples: "echo tzp=5 > info" sets the polling
frequency to 5 seconds, and "echo scp=1 > info" sets the cooling
preference to the passive/quiet mode (if supported by the ASL).
Implemented a workaround for a gcc bug that resuted in an OOPs
when loading the control method battery driver.
----------------------------------------
Summary of changes for this label: 09_20_01
ACPI CA Core Subsystem:
The AcpiEnableEvent and AcpiDisableEvent interfaces have been
modified to allow individual GPE levels to be flagged as wake-
enabled (i.e., these GPEs are to remain enabled when the platform
sleeps.)
The AcpiEnterSleepState and AcpiLeaveSleepState interfaces now
support wake-enabled GPEs. This means that upon entering the
sleep state, all GPEs that are not wake-enabled are disabled.
When leaving the sleep state, these GPEs are reenabled.
A local double-precision divide/modulo module has been added to
enhance portability to OS kernels where a 64-bit math library is
not available. The new module is "utmath.c".
Several optimizations have been made to reduce the use of CPU
stack. Originally over 2K, the maximum stack usage is now below
2K at 1860 bytes (1.82k)
Fixed a problem with the AcpiGetFirmwareTable interface where the
root table pointer was not mapped into a logical address properly.
Fixed a problem where a NULL pointer was being dereferenced in the
interpreter code for the ASL Notify operator.
Fixed a problem where the use of the ASL Revision operator
returned an error. This operator now returns the current version
of the ACPI CA core subsystem.
Fixed a problem where objects passed as control method parameters
to AcpiEvaluateObject were always deleted at method termination.
However, these objects may end up being stored into the namespace
by the called method. The object reference count mechanism was
applied to these objects instead of a force delete.
Fixed a problem where static strings or buffers (contained in the
AML code) that are declared as package elements within the ASL
code could cause a fault because the interpreter would attempt to
delete them. These objects are now marked with the "static
object" flag to prevent any attempt to delete them.
Implemented an interpreter optimization to use operands directly
from the state object instead of extracting the operands to local
variables. This reduces stack use and code size, and improves
performance.
The module exxface.c was eliminated as it was an unnecessary extra
layer of code.
Current core subsystem library code sizes are shown below. These
are the code and data sizes for the acpica.lib produced by the
Microsoft Visual C++ 6.0 compiler, and these values do not include
any ACPI driver or OSPM code. The debug version of the code

Linux:
Support for ACPI 2.0 64-bit integers has been added. All ACPI
Integer objects are now 64 bits wide
All Acpi data types and structures are now in lower case. Only
Acpi macros are upper case for differentiation.
Documentation:
Changes to the external interfaces as described above.
----------------------------------------
Summary of changes for this label: 08_31_01
ACPI CA Core Subsystem:
A bug with interpreter implementation of the ASL Divide operator
was found and fixed. The implicit function return value (not the
explicit store operands) was returning the remainder instead of
the quotient. This was a longstanding bug and it fixes several
known outstanding issues on various platforms.
The ACPI_DEBUG_PRINT and function trace entry/exit macros have
been further optimized for size. There are 700 invocations of the
DEBUG_PRINT macro alone, so each optimization reduces the size of
the debug version of the subsystem significantly.
A stack trace mechanism has been implemented. The maximum stack
usage is about 2K on 32-bit platforms. The debugger command "stat
stack" will display the current maximum stack usage.
All public symbols and global variables within the subsystem are
now prefixed with the string "Acpi". This keeps all of the
symbols grouped together in a kernel map, and avoids conflicts
with other kernel subsystems.
Most of the internal fixed lookup tables have been moved into the
code segment via the const operator.
Several enhancements have been made to the interpreter to both
reduce the code size and improve performance.
Current core subsystem library code sizes are shown below. These
are the code and data sizes for the acpica.lib produced by the
Microsoft Visual C++ 6.0 compiler, and these values do not include
any ACPI driver or OSPM code. The debug version of the code
includes the full debug trace mechanism which contains over 700
invocations of the DEBUG_PRINT macro, 500 function entry macro
invocations, and over 900 function exit macro invocations --
leading to a much larger code and data size. Note that these
values will vary depending on the efficiency of the compiler and
the compiler options used during generation.
Non-Debug Version: 64K Code, 5K Data, 69K Total
Debug Version: 137K Code, 58K Data, 195K Total
Linux:
Implemented wbinvd() macro, pending a kernel-wide definition.
Fixed /proc/acpi/event to handle poll() and short reads.
ASL Compiler, version X2026:
Fixed a problem introduced in the previous label where the AML
code emitted for package objects produced packages with zero
length.
----------------------------------------
Summary of changes for this label: 08_16_01
ACPI CA Core Subsystem:
The following ACPI 2.0 ASL operators have been implemented in the
AML interpreter (These are already supported by the Intel ASL
compiler): ToDecimalString, ToHexString, ToString, ToInteger, and
ToBuffer. Support for 64-bit AML constants is implemented in the
AML parser, debugger, and disassembler.
The internal memory tracking mechanism (leak detection code) has
been upgraded to reduce the memory overhead (a separate tracking
block is no longer allocated for each memory allocation), and now
supports all of the internal object caches.
The data structures and code for the internal object caches have
been coelesced and optimized so that there is a single cache and
memory list data structure and a single group of functions that
implement generic cache management. This has reduced the code
size in both the debug and release versions of the subsystem.
The DEBUG_PRINT macro(s) have been optimized for size and replaced
by ACPI_DEBUG_PRINT. The syntax for this macro is slightly
different, because it generates a single call to an internal
function. This results in a savings of about 90 bytes per
invocation, resulting in an overall code and data savings of about
16% in the debug version of the subsystem.
Linux:
Fixed C3 disk corruption problems and re-enabled C3 on supporting
machines.
Integrated low-level sleep code by Patrick Mochel.
Further tweaked source code Linuxization.
Other minor fixes.
ASL Compiler:
Support for ACPI 2.0 variable length packages is fixed/completed.
Fixed a problem where the optional length parameter for the ACPI
2.0 ToString operator.
Fixed multiple extraneous error messages when a syntax error is
detected within the declaration line of a control method.
----------------------------------------
Summary of changes for this label: 07_17_01
ACPI CA Core Subsystem:
Added a new interface named AcpiGetFirmwareTable to obtain any
ACPI table via the ACPI signature. The interface can be called at
any time during kernel initialization, even before the kernel
virtual memory manager is initialized and paging is enabled. This
allows kernel subsystems to obtain ACPI tables very early, even
before the ACPI CA subsystem is initialized.
Fixed a problem where Fields defined with the AnyAcc attribute
could be resolved to the incorrect address under the following
conditions: 1) the field width is larger than 8 bits and 2) the
parent operation region is not defined on a DWORD boundary.
Fixed a problem where the interpreter is not being locked during
namespace initialization (during execution of the _INI control
methods), causing an error when an attempt is made to release it
later.
ACPI 2.0 support in the AML Interpreter has begun and will be
ongoing throughout the rest of this year. In this label, The Mod
operator is implemented.
Added a new data type to contain full PCI addresses named
ACPI_PCI_ID. This structure contains the PCI Segment, Bus, Device,
and Function values.
Linux:
Enhanced the Linux version of the source code to change most
capitalized ACPI type names to lowercase. For example, all
instances of ACPI_STATUS are changed to acpi_status. This will
result in a large diff, but the change is strictly cosmetic and
aligns the CA code closer to the Linux coding standard.
OSL Interfaces:
The interfaces to the PCI configuration space have been changed to
add the PCI Segment number and to split the single 32-bit combined
DeviceFunction field into two 16-bit fields. This was
accomplished by moving the four values that define an address in
PCI configuration space (segment, bus, device, and function) to
the new ACPI_PCI_ID structure.
The changes to the PCI configuration space interfaces led to a
reexamination of the complete set of address space access
interfaces for PCI, I/O, and Memory. The previously existing 18
interfaces have proven difficult to maintain (any small change
must be propagated across at least 6 interfaces) and do not easily
allow for future expansion to 64 bits if necessary. Also, on some
systems, it would not be appropriate to demultiplex the access
width (8, 16, 32,or 64) before calling the OSL if the
corresponding native OS interfaces contain a similar access width
parameter. For these reasons, the 18 address space interfaces
have been replaced by these 6 new ones:
AcpiOsReadPciConfiguration
AcpiOsWritePciConfiguration
AcpiOsReadMemory
AcpiOsWriteMemory
AcpiOsReadPort
AcpiOsWritePort
Added a new interface named AcpiOsGetRootPointer to allow the OSL
to perform the platform and/or OS-specific actions necessary to
obtain the ACPI RSDP table pointer. On IA-32 platforms, this
interface will simply call down to the CA core to perform the low-
memory search for the table. On IA-64, the RSDP is obtained from
EFI. Migrating this interface to the OSL allows the CA core to
remain OS and platform independent.
Added a new interface named AcpiOsSignal to provide a generic
"function code and pointer" interface for various miscellaneous
signals and notifications that must be made to the host OS. The
first such signals are intended to support the ASL Fatal and
Breakpoint operators. In the latter case, the AcpiOsBreakpoint
interface has been obsoleted.
The definition of the AcpiFormatException interface has been
changed to simplify its use. The caller no longer must supply a
buffer to the call; A pointer to a const string is now returned
directly. This allows the call to be easily used in printf
statements, etc. since the caller does not have to manage a local
buffer.
ASL Compiler, Version X2025:
The ACPI 2.0 Switch/Case/Default operators have been implemented
and are fully functional. They will work with all ACPI 1.0
interpreters, since the operators are simply translated to If/Else
pairs.
The ACPI 2.0 ElseIf operator is implemented and will also work
with 1.0 interpreters, for the same reason.
Implemented support for ACPI 2.0 variable-length packages. These
packages have a separate opcode, and their size is determined by
the interpreter at run-time.
Documentation The ACPI CA Programmer Reference has been updated to
reflect the new interfaces and changes to existing interfaces.
------------------------------------------
Summary of changes for this label: 06_15_01
ACPI CA Core Subsystem:
Fixed a problem where a DWORD-accessed field within a Buffer
object would get its byte address inadvertently rounded down to
the nearest DWORD. Buffers are always Byte-accessible.
ASL Compiler, version X2024:
Fixed a problem where the Switch() operator would either fault or
hang the compiler. Note however, that the AML code for this ACPI
2.0 operator is not yet implemented.
Compiler uses the new AcpiOsGetTimer interface to obtain compile
timings.
Implementation of the CreateField operator automatically converts
a reference to a named field within a resource descriptor from a
byte offset to a bit offset if required.
Added some missing named fields from the resource descriptor
support. These are the names that are automatically created by the
compiler to reference fields within a descriptor. They are only
valid at compile time and are not passed through to the AML
interpreter.
Resource descriptor named fields are now typed as Integers and
subject to compile-time typechecking when used in expressions.
------------------------------------------
Summary of changes for this label: 05_18_01
ACPI CA Core Subsystem:
Fixed a couple of problems in the Field support code where bits
from adjacent fields could be returned along with the proper field
bits. Restructured the field support code to improve performance,
readability and maintainability.
New DEBUG_PRINTP macro automatically inserts the procedure name
into the output, saving hundreds of copies of procedure name
strings within the source, shrinking the memory footprint of the
debug version of the core subsystem.
Source Code Structure:
The source code directory tree was restructured to reflect the
current organization of the component architecture. Some files
and directories have been moved and/or renamed.
Linux:
Fixed leaking kacpidpc processes.
Fixed queueing event data even when /proc/acpi/event is not
opened.
ASL Compiler, version X2020:
Memory allocation performance enhancement - over 24X compile time
improvement on large ASL files. Parse nodes and namestring
buffers are now allocated from a large internal compiler buffer.
The temporary .SRC file is deleted unless the "-s" option is
specified
The "-d" debug output option now sends all output to the .DBG file
instead of the console.
"External" second parameter is now optional
"ElseIf" syntax now properly allows the predicate
Last operand to "Load" now recognized as a Target operand
Debug object can now be used anywhere as a normal object.
ResourceTemplate now returns an object of type BUFFER
EISAID now returns an object of type INTEGER
"Index" now works with a STRING operand
"LoadTable" now accepts optional parameters
"ToString" length parameter is now optional
"Interrupt (ResourceType," parse error fixed.
"Register" with a user-defined region space parse error fixed
Escaped backslash at the end of a string ("\\") scan/parse error
fixed
"Revision" is now an object of type INTEGER.
------------------------------------------
Summary of changes for this label: 05_02_01
Linux:
/proc/acpi/event now blocks properly.
Removed /proc/sys/acpi. You can still dump your DSDT from
/proc/acpi/dsdt.
ACPI CA Core Subsystem:
Fixed a problem introduced in the previous label where some of the
"small" resource descriptor types were not recognized.
Improved error messages for the case where an ASL Field is outside
the range of the parent operation region.
ASL Compiler, version X2018:
Added error detection for ASL Fields that extend beyond the length
of the parent operation region (only if the length of the region
is known at compile time.) This includes fields that have a
minimum access width that is smaller than the parent region, and
individual field units that are partially or entirely beyond the
extent of the parent.
------------------------------------------
Summary of changes for this label: 04_27_01
ACPI CA Core Subsystem:
Fixed a problem where the namespace mutex could be released at the
wrong time during execution of AcpiRemoveAddressSpaceHandler.
Added optional thread ID output for debug traces, to simplify
debugging of multiple threads. Added context switch notification
when the debug code realizes that a different thread is now
executing ACPI code.
Some additional external data types have been prefixed with the
string "ACPI_" for consistency. This may effect existing code.
The data types affected are the external callback typedefs - e.g.,
WALK_CALLBACK becomes ACPI_WALK_CALLBACK.
Linux:
Fixed an issue with the OSL semaphore implementation where a
thread was waking up with an error from receiving a SIGCHLD
signal.
Linux version of ACPI CA now uses the system C library for string
manipulation routines instead of a local implementation.
Cleaned up comments and removed TBDs.
ASL Compiler, version X2017:
Enhanced error detection and reporting for all file I/O
operations.
Documentation:
Programmer Reference updated to version 1.06.
------------------------------------------
Summary of changes for this label: 04_13_01
ACPI CA Core Subsystem:
Restructured support for BufferFields and RegionFields.
BankFields support is now fully operational. All known 32-bit
limitations on field sizes have been removed. Both BufferFields
and (Operation) RegionFields are now supported by the same field
management code.
Resource support now supports QWORD address and IO resources. The
16/32/64 bit address structures and the Extended IRQ structure
have been changed to properly handle Source Resource strings.
A ThreadId of -1 is now used to indicate a "mutex not acquired"
condition internally and must never be returned by AcpiOsThreadId.
This reserved value was changed from 0 since Unix systems allow a
thread ID of 0.
Linux:
Driver code reorganized to enhance portability
Added a kernel configuration option to control ACPI_DEBUG
Fixed the EC driver to honor _GLK.
ASL Compiler, version X2016:
Fixed support for the "FixedHw" keyword. Previously, the FixedHw
address space was set to 0, not 0x7f as it should be.
------------------------------------------
Summary of changes for this label: 03_13_01
ACPI CA Core Subsystem:
During ACPI initialization, the _SB_._INI method is now run if
present.
Notify handler fix - notifies are deferred until the parent method
completes execution. This fixes the "mutex already acquired"
issue seen occasionally.
Part of the "implicit conversion" rules in ACPI 2.0 have been
found to cause compatibility problems with existing ASL/AML. The
convert "result-to-target-type" implementation has been removed
for stores to method Args and Locals. Source operand conversion
is still fully implemented. Possible changes to ACPI 2.0
specification pending.
Fix to AcpiRsCalculatePciRoutingTableLength to return correct
length.
Fix for compiler warnings for 64-bit compiles.
Linux:
/proc output aligned for easier parsing.
Release-version compile problem fixed.
New kernel configuration options documented in Configure.help.
IBM 600E - Fixed Sleep button may generate "Invalid <NULL>
context" message.
OSPM:
Power resource driver integrated with bus manager.
Fixed kernel fault during active cooling for thermal zones.
Source Code:
The source code tree has been restructured.
------------------------------------------
Summary of changes for this label: 03_02_01
Linux OS Services Layer (OSL):
Major revision of all Linux-specific code.
Modularized all ACPI-specific drivers.
Added new thermal zone and power resource drivers.
Revamped /proc interface (new functionality is under /proc/acpi).
New kernel configuration options.
Linux known issues:
New kernel configuration options not documented in Configure.help
yet.
Module dependencies not currently implemented. If used, they
should be loaded in this order: busmgr, power, ec, system,
processor, battery, ac_adapter, button, thermal.
Modules will not load if CONFIG_MODVERSION is set.
IBM 600E - entering S5 may reboot instead of shutting down.
IBM 600E - Sleep button may generate "Invalid <NULL> context"
message.
Some systems may fail with "execution mutex already acquired"
message.
ACPI CA Core Subsystem:
Added a new OSL Interface, AcpiOsGetThreadId. This was required
for the deadlock detection code. Defined to return a non-zero, 32-
bit thread ID for the currently executing thread. May be a non-
zero constant integer on single-thread systems.
Implemented deadlock detection for internal subsystem mutexes. We
may add conditional compilation for this code (debug only) later.
ASL/AML Mutex object semantics are now fully supported. This
includes multiple acquires/releases by owner and support for the
Mutex SyncLevel parameter.
A new "Force Release" mechanism automatically frees all ASL
Mutexes that have been acquired but not released when a thread
exits the interpreter. This forces conformance to the ACPI spec
("All mutexes must be released when an invocation exits") and
prevents deadlocked ASL threads. This mechanism can be expanded
(later) to monitor other resource acquisitions if OEM ASL code
continues to misbehave (which it will).
Several new ACPI exception codes have been added for the Mutex
support.
Recursive method calls are now allowed and supported (the ACPI
spec does in fact allow recursive method calls.) The number of
recursive calls is subject to the restrictions imposed by the
SERIALIZED method keyword and SyncLevel (ACPI 2.0) method
parameter.
Implemented support for the SyncLevel parameter for control
methods (ACPI 2.0 feature)
Fixed a deadlock problem when multiple threads attempted to use
the interpreter.
Fixed a problem where the string length of a String package
element was not always set in a package returned from
AcpiEvaluateObject.
Fixed a problem where the length of a String package element was
not always included in the length of the overall package returned
from AcpiEvaluateObject.
Added external interfaces (Acpi*) to the ACPI debug memory
manager. This manager keeps a list of all outstanding
allocations, and can therefore detect memory leaks and attempts to
free memory blocks more than once. Useful for code such as the
power manager, etc. May not be appropriate for device drivers.
Performance with the debug code enabled is slow.
The ACPI Global Lock is now an optional hardware element.
ASL Compiler Version X2015:
Integrated changes to allow the compiler to be generated on
multiple platforms.
Linux makefile added to generate the compiler on Linux
Source Code:
All platform-specific headers have been moved to their own
subdirectory, Include/Platform.
New source file added, Interpreter/ammutex.c
New header file, Include/acstruct.h
Documentation:
The programmer reference has been updated for the following new
interfaces: AcpiOsGetThreadId AcpiAllocate AcpiCallocate AcpiFree
------------------------------------------
Summary of changes for this label: 02_08_01
Core ACPI CA Subsystem: Fixed a problem where an error was
incorrectly returned if the return resource buffer was larger than
the actual data (in the resource interfaces).
References to named objects within packages are resolved to the
full pathname string before packages are returned directly (via
the AcpiEvaluateObject interface) or indirectly via the resource
interfaces.
Linux OS Services Layer (OSL):
Improved /proc battery interface.
Added C-state debugging output and other miscellaneous fixes.
ASL Compiler Version X2014:
All defined method arguments can now be used as local variables,
including the ones that are not actually passed in as parameters.
The compiler tracks initialization of the arguments and issues an
exception if they are used without prior assignment (just like
locals).
The -o option now specifies a filename prefix that is used for all
output files, including the AML output file. Otherwise, the
default behavior is as follows: 1) the AML goes to the file
specified in the DSDT. 2) all other output files use the input
source filename as the base.
------------------------------------------
Summary of changes for this label: 01_25_01
Core ACPI CA Subsystem: Restructured the implementation of object
store support within the interpreter. This includes support for
the Store operator as well as any ASL operators that include a
target operand.
Partially implemented support for Implicit Result-to-Target
conversion. This is when a result object is converted on the fly
to the type of an existing target object. Completion of this
support is pending further analysis of the ACPI specification
concerning this matter.
CPU-specific code has been removed from the subsystem (hardware
directory).
New Power Management Timer functions added
Linux OS Services Layer (OSL): Moved system state transition code
to the core, fixed it, and modified Linux OSL accordingly.
Fixed C2 and C3 latency calculations.
We no longer use the compilation date for the version message on
initialization, but retrieve the version from AcpiGetSystemInfo().
Incorporated for fix Sony VAIO machines.
Documentation: The Programmer Reference has been updated and
reformatted.
ASL Compiler: Version X2013: Fixed a problem where the line
numbering and error reporting could get out of sync in the
presence of multiple include files.
------------------------------------------
Summary of changes for this label: 01_15_01
Core ACPI CA Subsystem:
Implemented support for type conversions in the execution of the
ASL Concatenate operator (The second operand is converted to
match the type of the first operand before concatenation.)
Support for implicit source operand conversion is partially
implemented. The ASL source operand types Integer, Buffer, and
String are freely interchangeable for most ASL operators and are
converted by the interpreter on the fly as required. Implicit
Target operand conversion (where the result is converted to the
target type before storing) is not yet implemented.
Support for 32-bit and 64-bit BCD integers is implemented.
Problem fixed where a field read on an aligned field could cause a
read past the end of the field.
New exception, AE_AML_NO_RETURN_VALUE, is returned when a method
does not return a value, but the caller expects one. (The ASL
compiler flags this as a warning.)
ASL Compiler:
Version X2011:
1. Static typechecking of all operands is implemented. This
prevents the use of invalid objects (such as using a Package where
an Integer is required) at compile time instead of at interpreter
run-time.
2. The ASL source line is printed with ALL errors and warnings.
3. Bug fix for source EOF without final linefeed.
4. Debug option is split into a parse trace and a namespace trace.
5. Namespace output option (-n) includes initial values for
integers and strings.
6. Parse-only option added for quick syntax checking.
7. Compiler checks for duplicate ACPI name declarations
Version X2012:
1. Relaxed typechecking to allow interchangeability between
strings, integers, and buffers. These types are now converted by
the interpreter at runtime.
2. Compiler reports time taken by each internal subsystem in the
debug output file.
------------------------------------------
Summary of changes for this label: 12_14_00
ASL Compiler:
This is the first official release of the compiler. Since the
compiler requires elements of the Core Subsystem, this label
synchronizes everything.
------------------------------------------
Summary of changes for this label: 12_08_00
Fixed a problem where named references within the ASL definition
of both OperationRegions and CreateXXXFields did not work
properly. The symptom was an AE_AML_OPERAND_TYPE during
initialization of the region/field. This is similar (but not
related internally) to the problem that was fixed in the last
label.
Implemented both 32-bit and 64-bit support for the BCD ASL
functions ToBCD and FromBCD.
Updated all legal headers to include "2000" in the copyright
years.
------------------------------------------
Summary of changes for this label: 12_01_00
Fixed a problem where method invocations within the ASL definition
of both OperationRegions and CreateXXXFields did not work
properly. The symptom was an AE_AML_OPERAND_TYPE during
initialization of the region/field:
nsinit-0209: AE_AML_OPERAND_TYPE while getting region arguments
[DEBG] ammonad-0284: Exec_monadic2_r/Not: bad operand(s)
(0x3005)
Fixed a problem where operators with more than one nested
subexpression would fail. The symptoms were varied, by mostly
AE_AML_OPERAND_TYPE errors. This was actually a rather serious
problem that has gone unnoticed until now.
Subtract (Add (1,2), Multiply (3,4))
Fixed a problem where AcpiGetHandle didn't quite get fixed in the
previous build (The prefix part of a relative path was handled
incorrectly).
Fixed a problem where Operation Region initialization failed if
the operation region name was a "namepath" instead of a simple
"nameseg". Symptom was an AE_NO_OPERAND error.
Fixed a problem where an assignment to a local variable via the
indirect RefOf mechanism only worked for the first such
assignment. Subsequent assignments were ignored.
------------------------------------------
Summary of changes for this label: 11_15_00
ACPI 2.0 table support with backwards support for ACPI 1.0 and the
0.71 extensions. Note: although we can read ACPI 2.0 BIOS tables,
the AML interpreter does NOT have support for the new 2.0 ASL
grammar terms at this time.
All ACPI hardware access is via the GAS structures in the ACPI 2.0
FADT.
All physical memory addresses across all platforms are now 64 bits
wide. Logical address width remains dependent on the platform
(i.e., "void *").
AcpiOsMapMemory interface changed to a 64-bit physical address.
The AML interpreter integer size is now 64 bits, as per the ACPI
2.0 specification.
For backwards compatibility with ACPI 1.0, ACPI tables with a
revision number less than 2 use 32-bit integers only.
Fixed a problem where the evaluation of OpRegion operands did not
always resolve them to numbers properly.
------------------------------------------
Summary of changes for this label: 10_20_00
Fix for CBN_._STA issue. This fix will allow correct access to
CBN_ OpRegions when the _STA returns 0x8.
Support to convert ACPI constants (Ones, Zeros, One) to actual
values before a package object is returned
Fix for method call as predicate to if/while construct causing
incorrect if/while behavior
Fix for Else block package lengths sometimes calculated wrong (if
block > 63 bytes)
Fix for Processor object length field, was always zero
Table load abort if FACP sanity check fails
Fix for problem with Scope(name) if name already exists
Warning emitted if a named object referenced cannot be found
(resolved) during method execution.
------------------------------------------
Summary of changes for this label: 9_29_00
New table initialization interfaces: AcpiInitializeSubsystem no
longer has any parameters AcpiFindRootPointer - Find the RSDP (if
necessary) AcpiLoadTables (RSDP) - load all tables found at RSDP-
>RSDT Obsolete Interfaces AcpiLoadFirmwareTables - replaced by
AcpiLoadTables
Note: These interface changes require changes to all existing OSDs
The PCI_Config default address space handler is always installed
at the root namespace object.
-------------------------------------------
Summary of changes for this label: 09_15_00
The new initialization architecture is implemented. New
interfaces are: AcpiInitializeSubsystem (replaces AcpiInitialize)
AcpiEnableSubsystem Obsolete Interfaces: AcpiLoadNamespace
(Namespace is automatically loaded when a table is loaded)
The ACPI_OPERAND_OBJECT has been optimized to shrink its size from
52 bytes to 32 bytes. There is usually one of these for every
namespace object, so the memory savings is significant.
Implemented just-in-time evaluation of the CreateField operators.
Bug fixes for IA-64 support have been integrated.
Additional code review comments have been implemented
The so-called "third pass parse" has been replaced by a final walk
through the namespace to initialize all operation regions (address
spaces) and fields that have not yet been initialized during the
execution of the various _INI and REG methods.
New file - namespace/nsinit.c
-------------------------------------------
Summary of changes for this label: 09_01_00
Namespace manager data structures have been reworked to change the
primary object from a table to a single object. This has
resulted in dynamic memory savings of 3X within the namespace and
2X overall in the ACPI CA subsystem.
Fixed problem where the call to AcpiEvFindPciRootBuses was
inadvertently left commented out.
Reduced the warning count when generating the source with the GCC
compiler.
Revision numbers added to each module header showing the
SourceSafe version of the file. Please refer to this version
number when giving us feedback or comments on individual modules.
The main object types within the subsystem have been renamed to
clarify their purpose:
ACPI_INTERNAL_OBJECT -> ACPI_OPERAND_OBJECT
ACPI_GENERIC_OP -> ACPI_PARSE_OBJECT
ACPI_NAME_TABLE_ENTRY -> ACPI_NAMESPACE_NODE
NOTE: no changes to the initialization sequence are included in
this label.
-------------------------------------------
Summary of changes for this label: 08_23_00
Fixed problem where TerminateControlMethod was being called
multiple times per method
Fixed debugger problem where single stepping caused a semaphore to
be oversignalled
Improved performance through additional parse object caching -
added ACPI_EXTENDED_OP type
-------------------------------------------
Summary of changes for this label: 08_10_00
Parser/Interpreter integration: Eliminated the creation of
complete parse trees for ACPI tables and control methods.
Instead, parse subtrees are created and then deleted as soon as
they are processed (Either entered into the namespace or executed
by the interpreter). This reduces the use of dynamic kernel
memory significantly. (about 10X)
Exception codes broken into classes and renumbered. Be sure to
recompile all code that includes acexcep.h. Hopefully we won't
have to renumber the codes again now that they are split into
classes (environment, programmer, AML code, ACPI table, and
internal).
Fixed some additional alignment issues in the Resource Manager
subcomponent
Implemented semaphore tracking in the AcpiExec utility, and fixed
several places where mutexes/semaphores were being unlocked
without a corresponding lock operation. There are no known
semaphore or mutex "leaks" at this time.
Fixed the case where an ASL Return operator is used to return an
unnamed package.
-------------------------------------------
Summary of changes for this label: 07_28_00
Fixed a problem with the way addresses were calculated in
AcpiAmlReadFieldData() and AcpiAmlWriteFieldData(). This problem
manifested itself when a Field was created with WordAccess or
DwordAccess, but the field unit defined within the Field was less
than a Word or Dword.
Fixed a problem in AmlDumpOperands() module's loop to pull
operands off of the operand stack to display information. The
problem manifested itself as a TLB error on 64-bit systems when
accessing an operand stack with two or more operands.
Fixed a problem with the PCI configuration space handlers where
context was getting confused between accesses. This required a
change to the generic address space handler and address space
setup definitions. Handlers now get both a global handler context
(this is the one passed in by the user when executing
AcpiInstallAddressSpaceHandler() and a specific region context
that is unique to each region (For example, the _ADR, _SEG and
_BBN values associated with a specific region). The generic
function definitions have changed to the following:
typedef ACPI_STATUS (*ADDRESS_SPACE_HANDLER) ( UINT32 Function,
UINT32 Address, UINT32 BitWidth, UINT32 *Value, void
*HandlerContext, // This used to be void *Context void
*RegionContext); // This is an additional parameter
typedef ACPI_STATUS (*ADDRESS_SPACE_SETUP) ( ACPI_HANDLE
RegionHandle, UINT32 Function, void *HandlerContext, void
**RegionContext); // This used to be **ReturnContext
-------------------------------------------
Summary of changes for this label: 07_21_00
Major file consolidation and rename. All files within the
interpreter have been renamed as well as most header files. This
was done to prevent collisions with existing files in the host
OSs -- filenames such as "config.h" and "global.h" seem to be
quite common. The VC project files have been updated. All
makefiles will require modification.
The parser/interpreter integration continues in Phase 5 with the
implementation of a complete 2-pass parse (the AML is parsed
twice) for each table; This avoids the construction of a huge
parse tree and therefore reduces the amount of dynamic memory
required by the subsystem. Greater use of the parse object cache
means that performance is unaffected.
Many comments from the two code reviews have been rolled in.
The 64-bit alignment support is complete.
-------------------------------------------
Summary of changes for this label: 06_30_00
With a nod and a tip of the hat to the technology of yesteryear,
we've added support in the source code for 80 column output
devices. The code is now mostly constrained to 80 columns or
less to support environments and editors that 1) cannot display
or print more than 80 characters on a single line, and 2) cannot
disable line wrapping.
A major restructuring of the namespace data structure has been
completed. The result is 1) cleaner and more
understandable/maintainable code, and 2) a significant reduction
in the dynamic memory requirement for each named ACPI object
(almost half).
-------------------------------------------
Summary of changes for this label: 06_23_00
Linux support has been added. In order to obtain approval to get
the ACPI CA subsystem into the Linux kernel, we've had to make
quite a few changes to the base subsystem that will affect all
users (all the changes are generic and OS- independent). The
effects of these global changes have been somewhat far reaching.
Files have been merged and/or renamed and interfaces have been
renamed. The major changes are described below.
Osd* interfaces renamed to AcpiOs* to eliminate namespace
pollution/confusion within our target kernels. All OSD
interfaces must be modified to match the new naming convention.
Files merged across the subsystem. A number of the smaller source
and header files have been merged to reduce the file count and
increase the density of the existing files. There are too many
to list here. In general, makefiles that call out individual
files will require rebuilding.
Interpreter files renamed. All interpreter files now have the
prefix am* instead of ie* and is*.
Header files renamed: The acapi.h file is now acpixf.h. The
acpiosd.h file is now acpiosxf.h. We are removing references to
the acronym "API" since it is somewhat windowsy. The new name is
"external interface" or xface or xf in the filenames.j
All manifest constants have been forced to upper case (some were
mixed case.) Also, the string "ACPI_" has been prepended to many
(not all) of the constants, typedefs, and structs.
The globals "DebugLevel" and "DebugLayer" have been renamed
"AcpiDbgLevel" and "AcpiDbgLayer" respectively.
All other globals within the subsystem are now prefixed with
"AcpiGbl_" Internal procedures within the subsystem are now
prefixed with "Acpi" (with only a few exceptions). The original
two-letter abbreviation for the subcomponent remains after "Acpi"
- for example, CmCallocate became AcpiCmCallocate.
Added a source code translation/conversion utility. Used to
generate the Linux source code, it can be modified to generate
other types of source as well. Can also be used to cleanup
existing source by removing extraneous spaces and blank lines.
Found in tools/acpisrc/*
OsdUnMapMemory was renamed to OsdUnmapMemory and then
AcpiOsUnmapMemory. (UnMap became Unmap).
A "MaxUnits" parameter has been added to AcpiOsCreateSemaphore.
When set to one, this indicates that the caller wants to use the
semaphore as a mutex, not a counting semaphore. ACPI CA uses
both types. However, implementers of this call may want to use
different OS primitives depending on the type of semaphore
requested. For example, some operating systems provide separate
"mutex" and "semaphore" interfaces - where the mutex interface is
much faster because it doesn't have all the overhead of a full
semaphore implementation.
Fixed a deadlock problem where a method that accesses the PCI
address space can block forever if it is the first access to the
space.
-------------------------------------------
Summary of changes for this label: 06_02_00
Support for environments that cannot handle unaligned data
accesses (e.g. firmware and OS environments devoid of alignment
handler technology namely SAL/EFI and the IA-64 Linux kernel) has
been added (via configurable macros) in these three areas: -
Transfer of data from the raw AML byte stream is done via byte
moves instead of word/dword/qword moves. - External objects are
aligned within the user buffer, including package elements (sub-
objects). - Conversion of name strings to UINT32 Acpi Names is now
done byte-wise.
The Store operator was modified to mimic Microsoft's
implementation when storing to a Buffer Field.
Added a check of the BM_STS bit before entering C3.
The methods subdirectory has been obsoleted and removed. A new
file, cmeval.c subsumes the functionality.
A 16-bit (DOS) version of AcpiExec has been developed. The
makefile is under the acpiexec directory.

*
* A seven character ASCII representation of the product
* identifier compressed into a 32-bit identifier. The seven
* character ID consists of a three character manufacturer code,
* a three character hexadecimal product identifier, and a one
* character hexadecimal revision number. The manufacturer code
* is a 3 uppercase character code that is compressed into 3 5-bit
* values as follows:
* 1) Find hex ASCII value for each letter
* 2) Subtract 40h from each ASCII value
* 3) Retain 5 least signficant bits for each letter by
* discarding upper 3 bits because they are always 0.
* 4) Compressed code = concatenate 0 and the 3 5-bit values
*
* The format of the compressed product identifier is as follows:
* Byte 0: Bit 7 - Reserved (0)
* Bits 6-2: - 1st character of compressed mfg code
* Bits 1-0 - Upper 2 bits of 2nd character of mfg code
* Byte 1: Bits 7-5 - Lower 3 bits of 2nd character of mfg code
* Bits 4-0 - 3rd character of mfg code
* Byte 2: Bits 7-4 - 1st hex digit of product number
* Bits 3-0 - 2nd hex digit of product number
* Byte 3: Bits 7-4 - 3st hex digit of product number
* Bits 3-0 - Hex digit of the revision number

Instructions for integrating iASL compiler into MS VC++ 6.0 environment.
Part 1. Integration as a custom tool
This procedure adds the iASL compiler as a custom tool that can be used
to compile ASL source files. The output is sent to the VC output
window.
a) Select Tools->Customize.
b) Select the "Tools" tab.
c) Scroll down to the bottom of the "Menu Contents" window. There you
will see an empty rectangle. Click in the rectangle to enter a
name for this tool.
d) Type "iASL Compiler" in the box and hit enter. You can now edit
the other fields for this new custom tool.
e) Enter the following into the fields:
Command: C:\Acpi\iasl.exe
Arguments: -e "$(FilePath)"
Initial Directory "$(FileDir)"
Use Output Window <Check this option>
"Command" must be the path to wherever you copied the compiler.
"-e" instructs the compiler to produce messages appropriate for VC.
Quotes around FilePath and FileDir enable spaces in filenames.
f) Select "Close".
These steps will add the compiler to the tools menu as a custom tool.
By enabling "Use Output Window", you can click on error messages in
the output window and the source file and source line will be
automatically displayed by VC. Also, you can use F4 to step through
the messages and the corresponding source line(s).
Part 2. Integration into a project build
This procedure creates a project that compiles ASL files to AML.
a) Create a new, empty project and add your .ASL files to the project
b) For all ASL files in the project, specify a custom build (under
Project/Settings/CustomBuild with the following settings (or similar):
Commands:
c:\acpi\libraries\iasl.exe -vs -vi "$(InputPath)"
Output:
$(InputDir)\$(InputPath).aml
Compiler Generation From Source
Generation of the ASL compiler from source code requires these items:
Required Tools
1) The Flex (or Lex) lexical analyzer generator.
2) The Bison (or Yacc) parser generator.
3) An ANSI C compiler.
Required Source Code.
There are three major source code components that are required to
generate the compiler:
1) The ASL compiler source.
2) The ACPI CA Core Subsystem source. In particular, the Namespace Manager
component is used to create an internal ACPI namespace and symbol table,
and the AML Interpreter is used to evaluate constant expressions.
3) The Common source for all ACPI components.

* Architecture-specific ACPICA Subsystem Data Types
*
* The goal of these types is to provide source code portability across
* 16-bit, 32-bit, and 64-bit targets.
*
* 1) The following types are of fixed size for all targets (16/32/64):
*
* BOOLEAN Logical boolean
*
* UINT8 8-bit (1 byte) unsigned value
* UINT16 16-bit (2 byte) unsigned value
* UINT32 32-bit (4 byte) unsigned value
* UINT64 64-bit (8 byte) unsigned value
*
* INT16 16-bit (2 byte) signed value
* INT32 32-bit (4 byte) signed value
* INT64 64-bit (8 byte) signed value
*
* COMPILER_DEPENDENT_UINT64/INT64 - These types are defined in the
* compiler-dependent header(s) and were introduced because there is no common
* 64-bit integer type across the various compilation models, as shown in
* the table below.
*
* Datatype LP64 ILP64 LLP64 ILP32 LP32 16bit
* char 8 8 8 8 8 8
* short 16 16 16 16 16 16
* _int32 32
* int 32 64 32 32 16 16
* long 64 64 32 32 32 32
* long long 64 64
* pointer 64 64 64 32 32 32
*
* Note: ILP64 and LP32 are currently not supported.
*
*
* 2) These types represent the native word size of the target mode of the
* processor, and may be 16-bit, 32-bit, or 64-bit as required. They are
* usually used for memory allocation, efficient loop counters, and array
* indexes. The types are similar to the size_t type in the C library and are
* required because there is no C type that consistently represents the native
* data width. ACPI_SIZE is needed because there is no guarantee that a
* kernel-level C library is present.
*
* ACPI_SIZE 16/32/64-bit unsigned value
* ACPI_NATIVE_INT 16/32/64-bit signed value

*
* The following conversions can be performed as necessary:
*
* Integer -> String
* Integer -> Buffer
* String -> Integer
* String -> Buffer
* Buffer -> Integer
* Buffer -> String
* Buffer -> Package of Integers
* Package -> Package of one Package
*
* Additional possible repairs:
*
* Optional/unnecessary NULL package elements removed
* Required package elements that are NULL replaced by Integer/String/Buffer
* Incorrect standalone package wrapped with required outer package
