| GNU LIBRARY GENERAL PUBLIC LICENSE |
| Version 2, June 1991 |
| Copyright (C) 1991 Free Software Foundation, Inc. |
| 675 Mass Ave, Cambridge, MA 02139, USA |
| Everyone is permitted to copy and distribute verbatim copies |
| of this license document, but changing it is not allowed. |
| [This is the first released version of the library GPL. It is |
| numbered 2 because it goes with version 2 of the ordinary GPL.] |
| Preamble |
| The licenses for most software are designed to take away your |
| freedom to share and change it. By contrast, the GNU General Public |
| Licenses are intended to guarantee your freedom to share and change |
| free software--to make sure the software is free for all its users. |
| This license, the Library General Public License, applies to some |
| specially designated Free Software Foundation software, and to any |
| other libraries whose authors decide to use it. You can use it for |
| your libraries, too. |
| When we speak of free software, we are referring to freedom, not |
| price. Our General Public Licenses are designed to make sure that you |
| have the freedom to distribute copies of free software (and charge for |
| this service if you wish), that you receive source code or can get it |
| if you want it, that you can change the software or use pieces of it |
| in new free programs; and that you know you can do these things. |
| To protect your rights, we need to make restrictions that forbid |
| anyone to deny you these rights or to ask you to surrender the rights. |
| These restrictions translate to certain responsibilities for you if |
| you distribute copies of the library, or if you modify it. |
| For example, if you distribute copies of the library, whether gratis |
| or for a fee, you must give the recipients all the rights that we gave |
| you. You must make sure that they, too, receive or can get the source |
| code. If you link a program with the library, you must provide |
| complete object files to the recipients so that they can relink them |
| with the library, after making changes to the library and recompiling |
| it. And you must show them these terms so they know their rights. |
| Our method of protecting your rights has two steps: (1) copyright |
| the library, and (2) offer you this license which gives you legal |
| permission to copy, distribute and/or modify the library. |
| Also, for each distributor's protection, we want to make certain |
| that everyone understands that there is no warranty for this free |
| library. If the library is modified by someone else and passed on, we |
| want its recipients to know that what they have is not the original |
| version, so that any problems introduced by others will not reflect on |
| the original authors' reputations. |
| Finally, any free program is threatened constantly by software |
| patents. We wish to avoid the danger that companies distributing free |
| software will individually obtain patent licenses, thus in effect |
| transforming the program into proprietary software. To prevent this, |
| we have made it clear that any patent must be licensed for everyone's |
| free use or not licensed at all. |
| Most GNU software, including some libraries, is covered by the ordinary |
| GNU General Public License, which was designed for utility programs. This |
| license, the GNU Library General Public License, applies to certain |
| designated libraries. This license is quite different from the ordinary |
| one; be sure to read it in full, and don't assume that anything in it is |
| the same as in the ordinary license. |
| The reason we have a separate public license for some libraries is that |
| they blur the distinction we usually make between modifying or adding to a |
| program and simply using it. Linking a program with a library, without |
| changing the library, is in some sense simply using the library, and is |
| analogous to running a utility program or application program. However, in |
| a textual and legal sense, the linked executable is a combined work, a |
| derivative of the original library, and the ordinary General Public License |
| treats it as such. |
| Because of this blurred distinction, using the ordinary General |
| Public License for libraries did not effectively promote software |
| sharing, because most developers did not use the libraries. We |
| concluded that weaker conditions might promote sharing better. |
| However, unrestricted linking of non-free programs would deprive the |
| users of those programs of all benefit from the free status of the |
| libraries themselves. This Library General Public License is intended to |
| permit developers of non-free programs to use free libraries, while |
| preserving your freedom as a user of such programs to change the free |
| libraries that are incorporated in them. (We have not seen how to achieve |
| this as regards changes in header files, but we have achieved it as regards |
| changes in the actual functions of the Library.) The hope is that this |
| will lead to faster development of free libraries. |
| The precise terms and conditions for copying, distribution and |
| modification follow. Pay close attention to the difference between a |
| "work based on the library" and a "work that uses the library". The |
| former contains code derived from the library, while the latter only |
| works together with the library. |
| Note that it is possible for a library to be covered by the ordinary |
| General Public License rather than by this special one. |
| GNU LIBRARY GENERAL PUBLIC LICENSE |
| TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION |
| 0. This License Agreement applies to any software library which |
| contains a notice placed by the copyright holder or other authorized |
| party saying it may be distributed under the terms of this Library |
| General Public License (also called "this License"). Each licensee is |
| addressed as "you". |
| A "library" means a collection of software functions and/or data |
| prepared so as to be conveniently linked with application programs |
| (which use some of those functions and data) to form executables. |
| The "Library", below, refers to any such software library or work |
| which has been distributed under these terms. A "work based on the |
| Library" means either the Library or any derivative work under |
| copyright law: that is to say, a work containing the Library or a |
| portion of it, either verbatim or with modifications and/or translated |
| straightforwardly into another language. (Hereinafter, translation is |
| included without limitation in the term "modification".) |
| "Source code" for a work means the preferred form of the work for |
| making modifications to it. For a library, complete source code means |
| all the source code for all modules it contains, plus any associated |
| interface definition files, plus the scripts used to control compilation |
| and installation of the library. |
| Activities other than copying, distribution and modification are not |
| covered by this License; they are outside its scope. The act of |
| running a program using the Library is not restricted, and output from |
| such a program is covered only if its contents constitute a work based |
| on the Library (independent of the use of the Library in a tool for |
| writing it). Whether that is true depends on what the Library does |
| and what the program that uses the Library does. |
| 1. You may copy and distribute verbatim copies of the Library's |
| complete source code as you receive it, in any medium, provided that |
| you conspicuously and appropriately publish on each copy an |
| appropriate copyright notice and disclaimer of warranty; keep intact |
| all the notices that refer to this License and to the absence of any |
| warranty; and distribute a copy of this License along with the |
| Library. |
| You may charge a fee for the physical act of transferring a copy, |
| and you may at your option offer warranty protection in exchange for a |
| fee. |
| 2. You may modify your copy or copies of the Library or any portion |
| of it, thus forming a work based on the Library, and copy and |
| distribute such modifications or work under the terms of Section 1 |
| above, provided that you also meet all of these conditions: |
| a) The modified work must itself be a software library. |
| b) You must cause the files modified to carry prominent notices |
| stating that you changed the files and the date of any change. |
| c) You must cause the whole of the work to be licensed at no |
| charge to all third parties under the terms of this License. |
| d) If a facility in the modified Library refers to a function or a |
| table of data to be supplied by an application program that uses |
| the facility, other than as an argument passed when the facility |
| is invoked, then you must make a good faith effort to ensure that, |
| in the event an application does not supply such function or |
| table, the facility still operates, and performs whatever part of |
| its purpose remains meaningful. |
| (For example, a function in a library to compute square roots has |
| a purpose that is entirely well-defined independent of the |
| application. Therefore, Subsection 2d requires that any |
| application-supplied function or table used by this function must |
| be optional: if the application does not supply it, the square |
| root function must still compute square roots.) |
| These requirements apply to the modified work as a whole. If |
| identifiable sections of that work are not derived from the Library, |
| and can be reasonably considered independent and separate works in |
| themselves, then this License, and its terms, do not apply to those |
| sections when you distribute them as separate works. But when you |
| distribute the same sections as part of a whole which is a work based |
| on the Library, the distribution of the whole must be on the terms of |
| this License, whose permissions for other licensees extend to the |
| entire whole, and thus to each and every part regardless of who wrote |
| it. |
| Thus, it is not the intent of this section to claim rights or contest |
| your rights to work written entirely by you; rather, the intent is to |
| exercise the right to control the distribution of derivative or |
| collective works based on the Library. |
| In addition, mere aggregation of another work not based on the Library |
| with the Library (or with a work based on the Library) on a volume of |
| a storage or distribution medium does not bring the other work under |
| the scope of this License. |
| 3. You may opt to apply the terms of the ordinary GNU General Public |
| License instead of this License to a given copy of the Library. To do |
| this, you must alter all the notices that refer to this License, so |
| that they refer to the ordinary GNU General Public License, version 2, |
| instead of to this License. (If a newer version than version 2 of the |
| ordinary GNU General Public License has appeared, then you can specify |
| that version instead if you wish.) Do not make any other change in |
| these notices. |
| Once this change is made in a given copy, it is irreversible for |
| that copy, so the ordinary GNU General Public License applies to all |
| subsequent copies and derivative works made from that copy. |
| This option is useful when you wish to copy part of the code of |
| the Library into a program that is not a library. |
| 4. You may copy and distribute the Library (or a portion or |
| derivative of it, under Section 2) in object code or executable form |
| under the terms of Sections 1 and 2 above provided that you accompany |
| it with the complete corresponding machine-readable source code, which |
| must be distributed under the terms of Sections 1 and 2 above on a |
| medium customarily used for software interchange. |
| If distribution of object code is made by offering access to copy |
| from a designated place, then offering equivalent access to copy the |
| source code from the same place satisfies the requirement to |
| distribute the source code, even though third parties are not |
| compelled to copy the source along with the object code. |
| 5. A program that contains no derivative of any portion of the |
| Library, but is designed to work with the Library by being compiled or |
| linked with it, is called a "work that uses the Library". Such a |
| work, in isolation, is not a derivative work of the Library, and |
| therefore falls outside the scope of this License. |
| However, linking a "work that uses the Library" with the Library |
| creates an executable that is a derivative of the Library (because it |
| contains portions of the Library), rather than a "work that uses the |
| library". The executable is therefore covered by this License. |
| Section 6 states terms for distribution of such executables. |
| When a "work that uses the Library" uses material from a header file |
| that is part of the Library, the object code for the work may be a |
| derivative work of the Library even though the source code is not. |
| Whether this is true is especially significant if the work can be |
| linked without the Library, or if the work is itself a library. The |
| threshold for this to be true is not precisely defined by law. |
| If such an object file uses only numerical parameters, data |
| structure layouts and accessors, and small macros and small inline |
| functions (ten lines or less in length), then the use of the object |
| file is unrestricted, regardless of whether it is legally a derivative |
| work. (Executables containing this object code plus portions of the |
| Library will still fall under Section 6.) |
| Otherwise, if the work is a derivative of the Library, you may |
| distribute the object code for the work under the terms of Section 6. |
| Any executables containing that work also fall under Section 6, |
| whether or not they are linked directly with the Library itself. |
| 6. As an exception to the Sections above, you may also compile or |
| link a "work that uses the Library" with the Library to produce a |
| work containing portions of the Library, and distribute that work |
| under terms of your choice, provided that the terms permit |
| modification of the work for the customer's own use and reverse |
| engineering for debugging such modifications. |
| You must give prominent notice with each copy of the work that the |
| Library is used in it and that the Library and its use are covered by |
| this License. You must supply a copy of this License. If the work |
| during execution displays copyright notices, you must include the |
| copyright notice for the Library among them, as well as a reference |
| directing the user to the copy of this License. Also, you must do one |
| of these things: |
| a) Accompany the work with the complete corresponding |
| machine-readable source code for the Library including whatever |
| changes were used in the work (which must be distributed under |
| Sections 1 and 2 above); and, if the work is an executable linked |
| with the Library, with the complete machine-readable "work that |
| uses the Library", as object code and/or source code, so that the |
| user can modify the Library and then relink to produce a modified |
| executable containing the modified Library. (It is understood |
| that the user who changes the contents of definitions files in the |
| Library will not necessarily be able to recompile the application |
| to use the modified definitions.) |
| b) Accompany the work with a written offer, valid for at |
| least three years, to give the same user the materials |
| specified in Subsection 6a, above, for a charge no more |
| than the cost of performing this distribution. |
| c) If distribution of the work is made by offering access to copy |
| from a designated place, offer equivalent access to copy the above |
| specified materials from the same place. |
| d) Verify that the user has already received a copy of these |
| materials or that you have already sent this user a copy. |
| For an executable, the required form of the "work that uses the |
| Library" must include any data and utility programs needed for |
| reproducing the executable from it. However, as a special exception, |
| the source code distributed need not include anything that is normally |
| distributed (in either source or binary form) with the major |
| components (compiler, kernel, and so on) of the operating system on |
| which the executable runs, unless that component itself accompanies |
| the executable. |
| It may happen that this requirement contradicts the license |
| restrictions of other proprietary libraries that do not normally |
| accompany the operating system. Such a contradiction means you cannot |
| use both them and the Library together in an executable that you |
| distribute. |
| 7. You may place library facilities that are a work based on the |
| Library side-by-side in a single library together with other library |
| facilities not covered by this License, and distribute such a combined |
| library, provided that the separate distribution of the work based on |
| the Library and of the other library facilities is otherwise |
| permitted, and provided that you do these two things: |
| a) Accompany the combined library with a copy of the same work |
| based on the Library, uncombined with any other library |
| facilities. This must be distributed under the terms of the |
| Sections above. |
| b) Give prominent notice with the combined library of the fact |
| that part of it is a work based on the Library, and explaining |
| where to find the accompanying uncombined form of the same work. |
| 8. You may not copy, modify, sublicense, link with, or distribute |
| the Library except as expressly provided under this License. Any |
| attempt otherwise to copy, modify, sublicense, link with, or |
| distribute the Library is void, and will automatically terminate your |
| rights under this License. However, parties who have received copies, |
| or rights, from you under this License will not have their licenses |
| terminated so long as such parties remain in full compliance. |
| 9. You are not required to accept this License, since you have not |
| signed it. However, nothing else grants you permission to modify or |
| distribute the Library or its derivative works. These actions are |
| prohibited by law if you do not accept this License. Therefore, by |
| modifying or distributing the Library (or any work based on the |
| Library), you indicate your acceptance of this License to do so, and |
| all its terms and conditions for copying, distributing or modifying |
| the Library or works based on it. |
| 10. Each time you redistribute the Library (or any work based on the |
| Library), the recipient automatically receives a license from the |
| original licensor to copy, distribute, link with or modify the Library |
| subject to these terms and conditions. You may not impose any further |
| restrictions on the recipients' exercise of the rights granted herein. |
| You are not responsible for enforcing compliance by third parties to |
| this License. |
| 11. If, as a consequence of a court judgment or allegation of patent |
| infringement or for any other reason (not limited to patent issues), |
| conditions are imposed on you (whether by court order, agreement or |
| otherwise) that contradict the conditions of this License, they do not |
| excuse you from the conditions of this License. If you cannot |
| distribute so as to satisfy simultaneously your obligations under this |
| License and any other pertinent obligations, then as a consequence you |
| may not distribute the Library at all. For example, if a patent |
| license would not permit royalty-free redistribution of the Library by |
| all those who receive copies directly or indirectly through you, then |
| the only way you could satisfy both it and this License would be to |
| refrain entirely from distribution of the Library. |
| If any portion of this section is held invalid or unenforceable under any |
| particular circumstance, the balance of the section is intended to apply, |
| and the section as a whole is intended to apply in other circumstances. |
| It is not the purpose of this section to induce you to infringe any |
| patents or other property right claims or to contest validity of any |
| such claims; this section has the sole purpose of protecting the |
| integrity of the free software distribution system which is |
| implemented by public license practices. Many people have made |
| generous contributions to the wide range of software distributed |
| through that system in reliance on consistent application of that |
| system; it is up to the author/donor to decide if he or she is willing |
| to distribute software through any other system and a licensee cannot |
| impose that choice. |
| This section is intended to make thoroughly clear what is believed to |
| be a consequence of the rest of this License. |
| 12. If the distribution and/or use of the Library is restricted in |
| certain countries either by patents or by copyrighted interfaces, the |
| original copyright holder who places the Library under this License may add |
| an explicit geographical distribution limitation excluding those countries, |
| so that distribution is permitted only in or among countries not thus |
| excluded. In such case, this License incorporates the limitation as if |
| written in the body of this License. |
| 13. The Free Software Foundation may publish revised and/or new |
| versions of the Library General Public License from time to time. |
| Such new versions will be similar in spirit to the present version, |
| but may differ in detail to address new problems or concerns. |
| Each version is given a distinguishing version number. If the Library |
| specifies a version number of this License which applies to it and |
| "any later version", you have the option of following the terms and |
| conditions either of that version or of any later version published by |
| the Free Software Foundation. If the Library does not specify a |
| license version number, you may choose any version ever published by |
| the Free Software Foundation. |
| 14. If you wish to incorporate parts of the Library into other free |
| programs whose distribution conditions are incompatible with these, |
| write to the author to ask for permission. For software which is |
| copyrighted by the Free Software Foundation, write to the Free |
| Software Foundation; we sometimes make exceptions for this. Our |
| decision will be guided by the two goals of preserving the free status |
| of all derivatives of our free software and of promoting the sharing |
| and reuse of software generally. |
| NO WARRANTY |
| 15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO |
| WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW. |
| EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR |
| OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY |
| KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE |
| IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR |
| PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE |
| LIBRARY IS WITH YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME |
| THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION. |
| 16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN |
| WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY |
| AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU |
| FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR |
| CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE |
| LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING |
| RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A |
| FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF |
| SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH |
| DAMAGES. |
| END OF TERMS AND CONDITIONS |
| Appendix: How to Apply These Terms to Your New Libraries |
| If you develop a new library, and you want it to be of the greatest |
| possible use to the public, we recommend making it free software that |
| everyone can redistribute and change. You can do so by permitting |
| redistribution under these terms (or, alternatively, under the terms of the |
| ordinary General Public License). |
| To apply these terms, attach the following notices to the library. It is |
| safest to attach them to the start of each source file to most effectively |
| convey the exclusion of warranty; and each file should have at least the |
| "copyright" line and a pointer to where the full notice is found. |
| <one line to give the library's name and a brief idea of what it does.> |
| Copyright (C) <year> <name of author> |
| This library is free software; you can redistribute it and/or |
| modify it under the terms of the GNU Library General Public |
| License as published by the Free Software Foundation; either |
| version 2 of the License, or (at your option) any later version. |
| This library is distributed in the hope that it will be useful, |
| but WITHOUT ANY WARRANTY; without even the implied warranty of |
| MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the GNU |
| Library General Public License for more details. |
| You should have received a copy of the GNU Library General Public |
| License along with this library; if not, write to the Free |
| Software Foundation, Inc., 675 Mass Ave, Cambridge, MA 02139, USA. |
| Also add information on how to contact you by electronic and paper mail. |
| You should also get your employer (if you work as a programmer) or your |
| school, if any, to sign a "copyright disclaimer" for the library, if |
| necessary. Here is a sample; alter the names: |
| Yoyodyne, Inc., hereby disclaims all copyright interest in the |
| library `Frob' (a library for tweaking knobs) written by James Random Hacker. |

| Mesa Cygwin/X11 Information |
| WARNING |
| ======= |
| If you installed X11 (packages xorg-x11-devel and xorg-x11-bin-dlls ) with the |
| latest setup.exe from Cygwin the GL (Mesa) libraries and include are already |
| installed in /usr/X11R6. |
| The following will explain how to "replace" them. |
| Installation |
| ============ |
| How to compile Mesa on Cygwin/X11 systems: |
| 1. Shared libs: |
| type 'make cygwin-sl'. |
| When finished, the Mesa DLL will be in the Mesa-x.y/lib/ and |
| Mesa-x.y/bin directories. |
| 2. Static libs: |
| type 'make cygwin-static'. |
| When finished, the Mesa libraries will be in the Mesa-x.y/lib/ directory. |
| Header and library files: |
| After you've compiled Mesa and tried the demos I recommend the following |
| procedure for "installing" Mesa. |
| Copy the Mesa include/GL directory to /usr/X11R6/include: |
| cp -a include/GL /usr/X11R6/include |
| Copy the Mesa library files to /usr/X11R6/lib: |
| cp -a lib/* /usr/X11R6ocal/lib |
| Copy the Mesa bin files (used by the DLL stuff) to /usr/X11R6/bin: |
| cp -a lib/cyg* /usr/X11R6/bin |
| Xt/Motif widgets: |
| If you want to use Mesa or OpenGL in your Xt/Motif program you can build |
| the widgets found in either the widgets-mesa or widgets-sgi directories. |
| The former were written for Mesa and the later are the original SGI |
| widgets. Look in those directories for more information. |
| For the Motif widgets you must have downloaded the lesstif package. |
| Using the library |
| ================= |
| Configuration options: |
| The file src/mesa/main/config.h has many parameters which you can adjust |
| such as maximum number of lights, clipping planes, maximum texture size, |
| etc. In particular, you may want to change DEPTH_BITS from 16 to 32 |
| if a 16-bit depth buffer isn't precise enough for your application. |
| Shared libraries: |
| If you compile shared libraries (Win32 DLLS) you may have to set an |
| environment variable to specify where the Mesa libraries are located. |
| Set the PATH variable to include /your-dir/Mesa-2.6/bin. |
| Otherwise, when you try to run a demo it may fail with a message saying |
| that one or more DLL couldn't be found. |
| Xt/Motif Widgets: |
| Two versions of the Xt/Motif OpenGL drawing area widgets are included: |
| widgets-sgi/ SGI's stock widgets |
| widgets-mesa/ Mesa-tuned widgets |
| Look in those directories for details |
| Togl: |
| Togl is an OpenGL/Mesa widget for Tcl/Tk. |
| See http://togl.sourceforge.net for more information. |
| X Display Modes: |
| Mesa supports RGB(A) rendering into almost any X visual type and depth. |
| The glXChooseVisual function tries its best to pick an appropriate visual |
| for the given attribute list. However, if this doesn't suit your needs |
| you can force Mesa to use any X visual you want (any supported by your |
| X server that is) by setting the MESA_RGB_VISUAL and MESA_CI_VISUAL |
| environment variables. When an RGB visual is requested, glXChooseVisual |
| will first look if the MESA_RGB_VISUAL variable is defined. If so, it |
| will try to use the specified visual. Similarly, when a color index |
| visual is requested, glXChooseVisual will look for the MESA_CI_VISUAL |
| variable. |
| The format of accepted values is: <visual-class> <depth> |
| Here are some examples: |
| using the C-shell: |
| % setenv MESA_RGB_VISUAL "TrueColor 8" // 8-bit TrueColor |
| % setenv MESA_CI_VISUAL "PseudoColor 12" // 12-bit PseudoColor |
| % setenv MESA_RGB_VISUAL "PseudoColor 8" // 8-bit PseudoColor |
| using the KornShell: |
| $ export MESA_RGB_VISUAL="TrueColor 8" |
| $ export MESA_CI_VISUAL="PseudoColor 12" |
| $ export MESA_RGB_VISUAL="PseudoColor 8" |
| Double buffering: |
| Mesa can use either an X Pixmap or XImage as the backbuffer when in |
| double buffer mode. Using GLX, the default is to use an XImage. The |
| MESA_BACK_BUFFER environment variable can override this. The valid |
| values for MESA_BACK_BUFFER are: Pixmap and XImage (only the first |
| letter is checked, case doesn't matter). |
| A pixmap is faster when drawing simple lines and polygons while an |
| XImage is faster when Mesa has to do pixel-by-pixel rendering. If you |
| need depth buffering the XImage will almost surely be faster. Exper- |
| iment with the MESA_BACK_BUFFER variable to see which is faster for |
| your application. |
| Colormaps: |
| When using Mesa directly or with GLX, it's up to the application writer |
| to create a window with an appropriate colormap. The aux, tk, and GLUT |
| toolkits try to minimize colormap "flashing" by sharing colormaps when |
| possible. Specifically, if the visual and depth of the window matches |
| that of the root window, the root window's colormap will be shared by |
| the Mesa window. Otherwise, a new, private colormap will be allocated. |
| When sharing the root colormap, Mesa may be unable to allocate the colors |
| it needs, resulting in poor color quality. This can happen when a |
| large number of colorcells in the root colormap are already allocated. |
| To prevent colormap sharing in aux, tk and GLUT, define the environment |
| variable MESA_PRIVATE_CMAP. The value isn't significant. |
| Gamma correction: |
| To compensate for the nonlinear relationship between pixel values |
| and displayed intensities, there is a gamma correction feature in |
| Mesa. Some systems, such as Silicon Graphics, support gamma |
| correction in hardware (man gamma) so you won't need to use Mesa's |
| gamma facility. Other systems, however, may need gamma adjustment |
| to produce images which look correct. If in the past you thought |
| Mesa's images were too dim, read on. |
| Gamma correction is controlled with the MESA_GAMMA environment |
| variable. Its value is of the form "Gr Gg Gb" or just "G" where |
| Gr is the red gamma value, Gg is the green gamma value, Gb is the |
| blue gamma value and G is one gamma value to use for all three |
| channels. Each value is a positive real number typically in the |
| range 1.0 to 2.5. The defaults are all 1.0, effectively disabling |
| gamma correction. Examples using csh: |
| % setenv MESA_GAMMA "2.3 2.2 2.4" // separate R,G,B values |
| % setenv MESA_GAMMA "2.0" // same gamma for R,G,B |
| The demos/gamma.c program may help you to determine reasonable gamma |
| value for your display. With correct gamma values, the color intensities |
| displayed in the top row (drawn by dithering) should nearly match those |
| in the bottom row (drawn as grays). |
| Alex De Bruyn reports that gamma values of 1.6, 1.6 and 1.9 work well |
| on HP displays using the HP-ColorRecovery technology. |
| Mesa implements gamma correction with a lookup table which translates |
| a "linear" pixel value to a gamma-corrected pixel value. There is a |
| small performance penalty. Gamma correction only works in RGB mode. |
| Also be aware that pixel values read back from the frame buffer will |
| not be "un-corrected" so glReadPixels may not return the same data |
| drawn with glDrawPixels. |
| For more information about gamma correction see: |
| http://www.inforamp.net/~poynton/notes/colour_and_gamma/GammaFAQ.html |
| Overlay Planes |
| Overlay planes in the frame buffer are supported by Mesa but require |
| hardware and X server support. To determine if your X server has |
| overlay support you can test for the SERVER_OVERLAY_VISUALS property: |
| xprop -root | grep SERVER_OVERLAY_VISUALS |
| HPCR glClear(GL_COLOR_BUFFER_BIT) dithering |
| If you set the MESA_HPCR_CLEAR environment variable then dithering |
| will be used when clearing the color buffer. This is only applicable |
| to HP systems with the HPCR (Color Recovery) system. |
| Extensions |
| ========== |
| There are three Mesa-specific GLX extensions at this time. |
| GLX_MESA_pixmap_colormap |
| This extension adds the GLX function: |
| GLXPixmap glXCreateGLXPixmapMESA( Display *dpy, XVisualInfo *visual, |
| Pixmap pixmap, Colormap cmap ) |
| It is an alternative to the standard glXCreateGLXPixmap() function. |
| Since Mesa supports RGB rendering into any X visual, not just True- |
| Color or DirectColor, Mesa needs colormap information to convert RGB |
| values into pixel values. An X window carries this information but a |
| pixmap does not. This function associates a colormap to a GLX pixmap. |
| See the xdemos/glxpixmap.c file for an example of how to use this |
| extension. |
| GLX_MESA_release_buffers |
| Mesa associates a set of ancillary (depth, accumulation, stencil and |
| alpha) buffers with each X window it draws into. These ancillary |
| buffers are allocated for each X window the first time the X window |
| is passed to glXMakeCurrent(). Mesa, however, can't detect when an |
| X window has been destroyed in order to free the ancillary buffers. |
| The best it can do is to check for recently destroyed windows whenever |
| the client calls the glXCreateContext() or glXDestroyContext() |
| functions. This may not be sufficient in all situations though. |
| The GLX_MESA_release_buffers extension allows a client to explicitly |
| deallocate the ancillary buffers by calling glxReleaseBuffersMESA() |
| just before an X window is destroyed. For example: |
| #ifdef GLX_MESA_release_buffers |
| glXReleaseBuffersMESA( dpy, window ); |
| #endif |
| XDestroyWindow( dpy, window ); |
| This extension is new in Mesa 2.0. |
| GLX_MESA_copy_sub_buffer |
| This extension adds the glXCopySubBufferMESA() function. It works |
| like glXSwapBuffers() but only copies a sub-region of the window |
| instead of the whole window. |
| This extension is new in Mesa version 2.6 |
| Summary of X-related environment variables: |
| MESA_RGB_VISUAL - specifies the X visual and depth for RGB mode (X only) |
| MESA_CI_VISUAL - specifies the X visual and depth for CI mode (X only) |
| MESA_BACK_BUFFER - specifies how to implement the back color buffer (X only) |
| MESA_PRIVATE_CMAP - force aux/tk libraries to use private colormaps (X only) |
| MESA_GAMMA - gamma correction coefficients (X only) |

| General Public License, see the LICENSE file for details. |
| This document is a preliminary introduction to help you get |
| started. For more detaile information consult the web page. |
| http://10-dencies.zkm.de/~mesa/ |
| Version 0.1 (Yes it's very alpha code so be warned!) |
| Contributors: |
| Emil Briggs (briggs@bucky.physics.ncsu.edu) |
| David Bucciarelli (tech.hmw@plus.it) |
| Andreas Schiffler (schiffler@zkm.de) |
| 1. Requirements: |
| Mesa 3.0. |
| An SMP capable machine running Linux 2.x |
| libpthread installed on your machine. |
| 2. What does MITS stand for? |
| MITS stands for Mesa Internal Threading System. By adding |
| internal threading to Mesa it should be possible to improve |
| performance of OpenGL applications on SMP machines. |
| 3. Do applications have to be recoded to take advantage of MITS? |
| No. The threading is internal to Mesa and transparent to |
| applications. |
| 4. Will all applications benefit from the current implementation of MITS? |
| No. This implementation splits the processing of the vertex buffer |
| over two threads. There is a certain amount of overhead involved |
| with the thread synchronization and if there is not enough work |
| to be done the extra overhead outweighs any speedup from using |
| dual processors. You will not for example see any speedup when |
| running Quake because it uses GL_POLYGON and there is only one |
| polygon for each vertex buffer processed. Test results on a |
| dual 200 Mhz. Pentium Pro system show that one needs around |
| 100-200 vertices in the vertex buffer before any there is any |
| appreciable benefit from the threading. |
| 5. Are there any parameters that I can tune to try to improve performance. |
| Yes. You can try to vary the size of the vertex buffer which is |
| define in VB_MAX located in the file src/vb.h from your top level |
| Mesa distribution. The number needs to be a multiple of 12 and |
| the optimum value will probably depend on the capabilities of |
| your machine and the particular application you are running. |
| 6. Are there any ways I can modify the application to improve its |
| performance with the MITS? |
| Yes. Try to use as many vertices between each Begin/End pair |
| as possbile. This will reduce the thread synchronization |
| overhead. |
| 7. What sort of speedups can I expect? |
| On some benchmarks performance gains of up to 30% have been |
| observerd. Others may see no gain at all and in a few rare |
| cases even some degradation. |
| 8. What still needs to be done? |
| Lots of testing and benchmarking. |
| A portable implementation that works within the Mesa thread API. |
| Threading of additional areas of Mesa to improve performance |
| even more. |
| Installation: |
| 1. This assumes that you already have a working Mesa 3.0 installation |
| from source. |
| 2. Place the tarball MITS.tar.gz in your top level Mesa directory. |
| 3. Unzip it and untar it. It will replace the following files in |
| your Mesa source tree so back them up if you want to save them. |
| README.MITS |
| Make-config |
| Makefile |
| mklib.glide |
| src/vbxform.c |
| src/vb.h |
| 4. Rebuild Mesa using the command |
| make linux-386-glide-mits |

| Info on using Mesa 3.0 with Linux Quake I and Quake II |
| Disclaimer |
| ---------- |
| I am _not_ a Quake expert by any means. I pretty much only run it to |
| test Mesa. There have been a lot of questions about Linux Quake and |
| Mesa so I'm trying to provide some useful info here. If this file |
| doesn't help you then you should look elsewhere for help. The Mesa |
| mailing list or the news://news.3dfx.com/3dfx.linux.glide newsgroup |
| might be good. |
| Again, all the information I have is in this file. Please don't email |
| me with questions. |
| If you have information to contribute to this file please send it to |
| me at brianp@elastic.avid.com |
| Linux Quake |
| ----------- |
| You can get Linux Quake from http://www.idsoftware.com/ |
| Quake I and II for Linux were tested with, and include, Mesa 2.6. You |
| shouldn't have too many problems if you simply follow the instructions |
| in the Quake distribution. |
| RedHat 5.0 Linux problems |
| ------------------------- |
| RedHat Linux 5.x uses the GNU C library ("glibc" or "libc6") whereas |
| previous RedHat and other Linux distributions use "libc5" for its |
| runtime C library. |
| Linux Quake I and II were compiled for libc5. If you compile Mesa |
| on a RedHat 5.x system the resulting libMesaGL.so file will not work |
| with Linux Quake because of the different C runtime libraries. |
| The symptom of this is a segmentation fault soon after starting Quake. |
| If you want to use a newer version of Mesa (like 3.x) with Quake on |
| RedHat 5.x then read on. |
| The solution to the C library problem is to force Mesa to use libc5. |
| libc5 is in /usr/i486-linux-libc5/lib on RedHat 5.x systems. |
| Emil Briggs (briggs@tick.physics.ncsu.edu) nicely gave me the following |
| info: |
| > I only know what works on a RedHat 5.0 distribution. RH5 includes |
| > a full set of libraries for both libc5 and glibc. The loader ld.so |
| > uses the libc5 libraries in /usr/i486-linux-libc5/lib for programs |
| > linked against libc5 while it uses the glibc libraries in /lib and |
| > /usr/lib for programs linked against glibc. |
| > |
| > Anyway I changed line 41 of mklib.glide to |

| > ./quake2 +set vid_ref gl |
| > kbd_mode -a |
| > reset |
| I've already patched the mklib.glide file. You'll have to start Quake |
| with the script shown above though. |

| Daryll Strauss writes: |
| Here's my thoughts on the problem. On a RH 5.x system, you can NOT build |
| a libc5 executable or library. Red Hat just doesn't include the right |
| stuff to do it. |
| Since Quake is a libc5 based application, you are in trouble. You need |
| libc5 libraries. |
| What can you do about it? Well there's a package called gcc5 that does |
| MOST of the right stuff to compile with libc5. (It brings back older |
| header files, makes appropriate symbolic links for libraries, and sets |
| up the compiler to use the correct directories) You can find gcc5 here: |
| ftp://ecg.mit.edu/pub/linux/gcc5-1.0-1.i386.rpm |
| No, this isn't quite enough. There are still a few tricks to getting |
| Mesa to compile as a libc5 application. First you have to make sure that |
| every compile uses gcc5 instead of gcc. Second, in some cases the link |
| line actually lists -L/usr/lib which breaks gcc5 (because it forces you |
| to use the glibc version of things) |
| If you get all the stuff correctly compiled with gcc5 it should work. |
| I've run Mesa 3.0B6 and its demos in a window with my Rush on a Red Hat |
| 5.1 system. It is a big hassle, but it can be done. I've only made Quake |
| segfault, but I think that's from my libRush using the wrong libc. |
| Yes, mixing libc5 and glibc is a major pain. I've been working to get |
| all my libraries compiling correctly with this setup. Someone should |
| make an RPM out of it and feed changes back to Brian once they get it |
| all working. If no one else has done so by the time I get the rest of my |
| stuff straightened out, I'll try to do it myself. |

| It was redesigned in Mesa 3.3 so that thread safety is |
| supported by default (on systems which support threads, |
| that is). There is no measurable penalty on single |
| threaded applications. |
| NOTE that the only _driver_ which is thread safe at this time |
| is the OS/Mesa driver! |
| At present the mthreads code supports three thread APIS: |
| 1) POSIX threads (aka pthreads). |
| 2) Solaris / Unix International threads. |
| 3) Win32 threads (Win 95/NT). |
| Support for other thread libraries can be added src/glthread.[ch] |
| In order to guarantee proper operation, it is |
| necessary for both Mesa and application code to use the same threads API. |
| So, if your application uses Sun's thread API, then you should build Mesa |
| using one of the targets for Sun threads. |
| The mtdemos directory contains some example programs which use |
| multiple threads to render to osmesa rendering context(s). |
| Linux users should be aware that there exist many different POSIX |
| threads packages. The best solution is the linuxthreads package |
| (http://pauillac.inria.fr/~xleroy/linuxthreads/) as this package is the |
| only one that really supports multiprocessor machines (AFAIK). See |
| http://pauillac.inria.fr/~xleroy/linuxthreads/README for further |
| information about the usage of linuxthreads. |
| If you are interested in helping with thread safety work in Mesa |
| join the Mesa developers mailing list and post your proposal. |

| Quick Start |
| ----- ----- |
| Windows drivers are build with SCons. Makefiles or Visual Studio projects are |
| no longer shipped or supported. |
| Run |
| scons osmesa mesagdi |
| to build classic mesa Windows GDI drivers; or |
| scons libgl-gdi |
| to build gallium based GDI driver. |
| This will work both with MSVS or Mingw. |
| Windows Drivers |
| ------- ------- |
| At this time, only the gallium GDI driver is known to work. |
| Source code also exists in the tree for other drivers in |
| src/mesa/drivers/windows, but the status of this code is unknown. |
| Recipe |
| ------ |
| Building on windows requires several open-source packages. These are |
| steps that work as of this writing. |
| 1) install python 2.7 |
| 2) install scons (latest) |
| 3) install mingw, flex, and bison |
| 4) install libxml2 from here: http://www.lfd.uci.edu/~gohlke/pythonlibs |
| get libxml2-python-2.9.1.win-amd64-py2.7.exe |
| 5) install pywin32 from here: http://www.lfd.uci.edu/~gohlke/pythonlibs |
| get pywin32-218.4.win-amd64-py2.7.exe |
| 6) install git |
| 7) download mesa from git |
| see http://www.mesa3d.org/repository.html |
| 8) run scons |
| General |
| ------- |
| After building, you can copy the above DLL files to a place in your |
| PATH such as $SystemRoot/SYSTEM32. If you don't like putting things |
| in a system directory, place them in the same directory as the |
| executable(s). Be careful about accidentially overwriting files of |
| the same name in the SYSTEM32 directory. |
| The DLL files are built so that the external entry points use the |
| stdcall calling convention. |
| Static LIB files are not built. The LIB files that are built with are |
| the linker import files associated with the DLL files. |
| The si-glu sources are used to build the GLU libs. This was done |
| mainly to get the better tessellator code. |
| If you have a Windows-related build problem or question, please post |
| to the mesa-dev or mesa-users list. |

| <h2>Topogun</h2> |
| <p> |
| <a href="http://www.topogun.com/">Topogun</a> for Linux (version 2, at least) |
| creates a GLX visual without requesting a depth buffer. |
| This causes bad rendering if the OpenGL driver happens to choose a visual |

| Mesa 9.1.2 and later (will) support a DRI configuration option to work around |

| Using the <a href="http://dri.freedesktop.org/wiki/DriConf">driconf</a> tool, |
| set the "Create all visuals with a depth buffer" option before running Topogun. |
| Then, all GLX visuals will be created with a depth buffer. |
| </p> |
| <h2>Old OpenGL games</h2> |
| <p> |
| Some old OpenGL games (approx. ten years or older) may crash during |
| start-up because of an extension string buffer-overflow problem. |
| </p> |
| <p> |
| The problem is a modern OpenGL driver will return a very long string |
| for the glGetString(GL_EXTENSIONS) query and if the application |
| naively copies the string into a fixed-size buffer it can overflow the |
| buffer and crash the application. |
| </p> |
| <p> |
| The work-around is to set the MESA_EXTENSION_MAX_YEAR environment variable |
| to the approximate release year of the game. |
| This will cause the glGetString(GL_EXTENSIONS) query to only report extensions |
| older than the given year. |
| </p> |
| <p> |
| For example, if the game was released in 2001, do |
| <pre> |
| export MESA_EXTENSION_MAX_YEAR=2001 |
| </pre> |
| before running the game. |

| <h2 id="basic">1. Basic Usage</h2> |
| <p> |
| The autoconf generated configure script can be used to guess your |
| platform and change various options for building Mesa. To use the |
| configure script, type: |
| </p> |
| <pre> |
| ./configure |
| </pre> |
| <p> |
| To see a short description of all the options, type <code>./configure |
| --help</code>. If you are using a development snapshot and the configure |
| script does not exist, type <code>./autogen.sh</code> to generate it |
| first. If you know the options you want to pass to |
| <code>configure</code>, you can pass them to <code>autogen.sh</code>. It |
| will run <code>configure</code> with these options after it is |
| generated. Once you have run <code>configure</code> and set the options |
| to your preference, type: |
| </p> |
| <pre> |
| make |
| </pre> |
| <p> |
| This will produce libGL.so and several other libraries depending on the |
| options you have chosen. Later, if you want to rebuild for a different |
| configuration run <code>make realclean</code> before rebuilding. |
| </p> |
| <p> |
| Some of the generic autoconf options are used with Mesa: |
| </p> |
| <dl> |
| <dt><code>--prefix=PREFIX</code></dt> |
| <dd><p>This is the root directory where |
| files will be installed by <code>make install</code>. The default is |
| <code>/usr/local</code>.</p> |
| </dd> |
| <dt><code>--exec-prefix=EPREFIX</code></dt> |
| <dd><p>This is the root directory |
| where architecture-dependent files will be installed. In Mesa, this is |
| only used to derive the directory for the libraries. The default is |
| <code>${prefix}</code>.</p> |
| </dd> |
| <dt><code>--libdir=LIBDIR</code></dt> |
| <dd><p>This option specifies the directory |
| where the GL libraries will be installed. The default is |
| <code>${exec_prefix}/lib</code>. It also serves as the name of the |
| library staging area in the source tree. For instance, if the option |
| <code>--libdir=/usr/local/lib64</code> is used, the libraries will be |
| created in a <code>lib64</code> directory at the top of the Mesa source |
| tree.</p> |
| </dd> |
| <dt><code>--enable-static, --disable-shared</code></dt> |
| <dd><p>By default, Mesa |
| will build shared libraries. Either of these options will force static |
| libraries to be built. It is not currently possible to build static and |
| shared libraries in a single pass.</p> |
| </dd> |
| <dt><code>CC, CFLAGS, CXX, CXXFLAGS</code></dt> |
| <dd><p>These environment variables |
| control the C and C++ compilers used during the build. By default, |
| <code>gcc</code> and <code>g++</code> are used with the options |
| <code>"-g -O2"</code>.</p> |
| </dd> |
| <dt><code>LDFLAGS</code></dt> |
| <dd><p>An environment variable specifying flags to |
| pass when linking programs. These are normally empty, but can be used |
| to direct the linker to use libraries in nonstandard directories. For |
| example, <code>LDFLAGS="-L/usr/X11R6/lib"</code>.</p> |
| </dd> |
| <dt><code>PKG_CONFIG_PATH</code></dt> |
| <dd><p>When available, the |
| <code>pkg-config</code> utility is used to search for external libraries |
| on the system. This environment variable is used to control the search |
| path for <code>pkg-config</code>. For instance, setting |
| <code>PKG_CONFIG_PATH=/usr/X11R6/lib/pkgconfig</code> will search for |
| package metadata in <code>/usr/X11R6</code> before the standard |
| directories.</p> |
| </dd> |
| </dl> |
| <p> |
| There are also a few general options for altering the Mesa build: |
| </p> |
| <dl> |
| <dt><code>--with-x</code></dt> |
| <dd><p>When the X11 development libraries are |
| needed, the <code>pkg-config</code> utility <a href="#pkg-config">will |
| be used</a> for locating them. If they cannot be found through |
| <code>pkg-config</code> a fallback routing using <code>imake</code> will |
| be used. In this case, the <code>--with-x</code>, |
| <code>--x-includes</code> and <code>--x-libraries</code> options can |
| control the use of X for Mesa.</p> |
| </dd> |
| <dt><code>--enable-gl-osmesa</code></dt> |
| <dd><p>The <a href="osmesa.html">OSMesa |
| library</a> can be built on top of libGL for drivers that provide it. |
| This option controls whether to build libOSMesa. By default, this is |
| enabled for the Xlib driver and disabled otherwise. Note that this |
| option is different than using OSMesa as the driver.</p> |
| </dd> |
| <dt><code>--enable-debug</code></dt> |
| <dd><p>This option will enable compiler |
| options and macros to aid in debugging the Mesa libraries.</p> |
| </dd> |
| <dt><code>--disable-asm</code></dt> |
| <dd><p>There are assembly routines |
| available for a few architectures. These will be used by default if |
| one of these architectures is detected. This option ensures that |
| assembly will not be used.</p> |
| </dd> |
| <dt><code>--enable-32-bit</code></dt> |
| <dt><code>--enable-64-bit</code></dt> |
| <dd><p>By default, the |
| build will compile code as directed by the environment variables |
| <code>CC</code>, <code>CFLAGS</code>, etc. If the compiler is |
| <code>gcc</code>, these options offer a helper to add the compiler flags |
| to force 32- or 64-bit code generation as used on the x86 and x86_64 |
| architectures.</p> |
| </dd> |
| </dl> |
| <h2 id="driver">2. Driver Options</h2> |
| <p> |
| There are several different driver modes that Mesa can use. These are |
| described in more detail in the <a href="install.html">basic |
| installation instructions</a>. The Mesa driver is controlled through the |
| configure option --with-driver. There are currently three supported |
| options in the configure script. |
| </p> |
| <h3 id="xlib">Xlib</h3><p>This is the default mode for building Mesa. |
| It uses Xlib as a software renderer to do all rendering. It corresponds |
| to the option <code>--with-driver=xlib</code>. The libX11 and libXext |
| libraries, as well as the X11 development headers, will be need to |
| support the Xlib driver. |
| <h3 id="dri">DRI</h3><p>This mode uses the DRI hardware drivers for |
| accelerated OpenGL rendering. Enable the DRI drivers with the option |
| <code>--with-driver=dri</code>. See the <a href="install.html">basic |
| installation instructions</a> for details on prerequisites for the DRI |
| drivers. |
| <!-- DRI specific options --> |
| <dl> |
| <dt><code>--with-dri-driverdir=DIR</code> |
| <dd><p> This option specifies the |
| location the DRI drivers will be installed to and the location libGL |
| will search for DRI drivers. The default is <code>${libdir}/dri</code>. |
| <dt><code>--with-dri-drivers=DRIVER,DRIVER,...</code> |
| <dd><p> This option |
| allows a specific set of DRI drivers to be built. For example, |
| <code>--with-dri-drivers="swrast,i965,radeon,nouveau"</code>. By |
| default, the drivers will be chosen depending on the target platform. |
| See the directory <code>src/mesa/drivers/dri</code> in the source tree |
| for available drivers. Beware that the swrast DRI driver is used by both |
| libGL and the X.Org xserver GLX module to do software rendering, so you |
| may run into problems if it is not available. |
| <!-- This explanation might be totally bogus. Kristian? --> |
| <dt><code>--disable-driglx-direct</code> |
| <dd><p> Disable direct rendering in |
| GLX. Normally, direct hardware rendering through the DRI drivers and |
| indirect software rendering are enabled in GLX. This option disables |
| direct rendering entirely. It can be useful on architectures where |
| kernel DRM modules are not available. |
| <dt><code>--enable-glx-tls</code> <dd><p> |
| Enable Thread Local Storage (TLS) in |
| GLX. |
| <dt><code>--with-expat=DIR</code> <dd> The DRI-enabled libGL uses expat to |
| parse the DRI configuration files in <code>/etc/drirc</code> and |
| <code>~/.drirc</code>. This option allows a specific expat installation |
| to be used. For example, <code>--with-expat=/usr/local</code> will |
| search for expat headers and libraries in <code>/usr/local/include</code> |
| and <code>/usr/local/lib</code>, respectively. |
| </dl> |
| <h3 id="osmesa">OSMesa </h3><p> No libGL is built in this |
| mode. Instead, the driver code is built into the Off-Screen Mesa |
| (OSMesa) library. See the <a href="osmesa.html">Off-Screen Rendering</a> |
| page for more details. |
| <!-- OSMesa specific options --> |
| <dl> |
| <dt><code>--with-osmesa-bits=BITS</code> |
| <dd><p> This option allows the size |
| of the color channel in bits to be specified. By default, an 8-bit |
| channel will be used, and the driver will be named libOSMesa. Other |
| options are 16- and 32-bit color channels, which will add the bit size |
| to the library name. For example, <code>--with-osmesa-bits=16</code> |
| will create the libOSMesa16 library with a 16-bit color channel. |
| </dl> |
| <h2 id="library">3. Library Options</h2> |
| <p> |
| The configure script provides more fine grained control over the GL |
| libraries that will be built. More details on the specific GL libraries |
| can be found in the <a href="install.html">basic installation |
| instructions</a>. |

| <p> |
| The SGI OpenGL conformance tests verify correct operation of OpenGL |
| implementations. I, Brian Paul, have been given a copy of the tests |
| for testing Mesa. The tests are not publically available. |
| </p> |
| <p> |
| This file has the latest results of testing Mesa with the OpenGL 1.2 |
| conformance tests. Testing with the preliminary OpenGL 1.3 tests has |
| also been done. Mesa passes all the 1.3 tests. |
| </p> |
| <p> |
| The tests were run using the software X11 device driver on 24-bpp |
| and 16-bpp displays. |
| </p> |
| <p> |
| Mesa 4.0 and later pass all conformance tests at all path levels. |
| Note that this says nothing about the conformance of hardware drivers |
| based upon Mesa. |

| <h1>Debugging Tips</h1> |
| <p> |
| Normally Mesa (and OpenGL) records but does not notify the user of |
| errors. It is up to the application to call |
| <code>glGetError</code> to check for errors. Mesa supports an |
| environment variable, MESA_DEBUG, to help with debugging. If |
| MESA_DEBUG is defined, a message will be printed to stdout whenever |
| an error occurs. |
| </p> |
| <p> |
| More extensive error checking is done when Mesa is compiled with the |
| DEBUG symbol defined. You'll have to edit the Make-config file and |
| add -DDEBUG to the CFLAGS line for your system configuration. You may |
| also want to replace any optimization flags with the -g flag so you can |
| use your debugger. After you've edited Make-config type 'make clean' |
| before recompiling. |
| </p> |
| <p> |
| In your debugger you can set a breakpoint in _mesa_error() to trap Mesa |
| errors. |
| </p> |
| <p> |
| There is a display list printing/debugging facility. See the end of |
| src/dlist.c for details. |

| <p> |
| Both professional and volunteer developers contribute to Mesa. |
| </p> |
| <p> |
| <a href="http://www.vmware.com/">VMware</a> |
| employs several of the main Mesa developers including Brian Paul |
| and Keith Whitwell. |
| </p> |
| <p> |
| In the past, Tungsten Graphics contracts implemented many Mesa features |
| including: |
| </p> |
| <ul> |
| <li>DRI drivers for Intel i965, i945, i915 and other chips |
| <li>Advanced memory manager and framebuffer object support |
| <li>Shading language compiler and OpenGL 2.0 support |
| <li>MiniGLX environment |
| </ul> |
| <p> |
| Other companies including |
| <a href="http://www.intellinuxgraphics.org/index.html">Intel</a> |
| and RedHat also actively contribute to the project. |
| Intel has recently contributed the new GLSL compiler in Mesa 7.9. |
| </p> |
| <p> |
| <a href="http://www.lunarg.com/">LunarG</a> can be contacted |
| for custom Mesa / 3D graphics development. |
| </p> |
| <p> |
| Volunteers have made significant contributions to all parts of Mesa, including |
| complete device drivers. |

| <h2>Adding Extentions</h2> |
| <p> |
| To add a new GL extension to Mesa you have to do at least the following. |
| <ul> |
| <li> |
| If glext.h doesn't define the extension, edit include/GL/gl.h and add |
| code like this: |
| <pre> |
| #ifndef GL_EXT_the_extension_name |
| #define GL_EXT_the_extension_name 1 |
| /* declare the new enum tokens */ |
| /* prototype the new functions */ |
| /* TYPEDEFS for the new functions */ |
| #endif |
| </pre> |
| </li> |
| <li> |
| In the src/mesa/glapi/ directory, add the new extension functions and |
| enums to the gl_API.xml file. |
| Then, a bunch of source files must be regenerated by executing the |
| corresponding Python scripts. |
| </li> |
| <li> |
| Add a new entry to the <code>gl_extensions</code> struct in mtypes.h |
| </li> |
| <li> |
| Update the <code>extensions.c</code> file. |
| </li> |
| <li> |
| From this point, the best way to proceed is to find another extension, |
| similar to the new one, that's already implemented in Mesa and use it |
| as an example. |
| </li> |
| <li> |
| If the new extension adds new GL state, the functions in get.c, enable.c |
| and attrib.c will most likely require new code. |
| </li> |
| </ul> |
| <h2>Coding Style</h2> |
| <p> |
| Mesa's code style has changed over the years. Here's the latest. |
| </p> |
| <p> |
| Comment your code! It's extremely important that open-source code be |
| well documented. Also, strive to write clean, easily understandable code. |
| </p> |
| <p> |
| 3-space indentation |
| </p> |
| <p> |
| If you use tabs, set them to 8 columns |
| </p> |
| <p> |
| Line width: the preferred width to fill comments and code in Mesa is 78 |
| columns. Exceptions are sometimes made for clarity (e.g. tabular data is |
| sometimes filled to a much larger width so that extraneous carriage returns |
| don't obscure the table). |
| </p> |
| <p> |
| Brace example: |
| </p> |
| <pre> |
| if (condition) { |
| foo; |
| } |
| else { |
| bar; |
| } |
| switch (condition) { |
| case 0: |
| foo(); |
| break; |
| case 1: { |
| ... |
| break; |
| } |
| default: |
| ... |
| break; |
| } |
| </pre> |
| <p> |
| Here's the GNU indent command which will best approximate my preferred style: |
| (Note that it won't format switch statements in the preferred way) |
| </p> |
| <pre> |
| indent -br -i3 -npcs --no-tabs infile.c -o outfile.c |
| </pre> |
| <p> |
| Local variable name example: localVarName (no underscores) |
| </p> |
| <p> |
| Constants and macros are ALL_UPPERCASE, with _ between words |
| </p> |
| <p> |
| Global variables are not allowed. |
| </p> |
| <p> |
| Function name examples: |
| </p> |
| <pre> |
| glFooBar() - a public GL entry point (in glapi_dispatch.c) |
| _mesa_FooBar() - the internal immediate mode function |
| save_FooBar() - retained mode (display list) function in dlist.c |
| foo_bar() - a static (private) function |
| _mesa_foo_bar() - an internal non-static Mesa function |
| </pre> |
| <p> |
| Places that are not directly visible to the GL API should prefer the use |
| of <tt>bool</tt>, <tt>true</tt>, and |
| <tt>false</tt> over <tt>GLboolean</tt>, <tt>GL_TRUE</tt>, and |
| <tt>GL_FALSE</tt>. In C code, this may mean that |
| <tt>#include <stdbool.h></tt> needs to be added. The |
| <tt>try_emit_</tt>* methods in src/mesa/program/ir_to_mesa.cpp and |
| src/mesa/state_tracker/st_glsl_to_tgsi.cpp can serve as examples. |
| </p> |
| <h2>Marking a commit as a candidate for a stable branch</h2> |
| <p> |
| If you want a commit to be applied to a stable branch, |
| you should add an appropriate note to the commit message. |
| </p> |
| <p> |
| Here are some examples of such a note: |
| </p> |
| <ul> |
| <li>NOTE: This is a candidate for the 9.0 branch.</li> |
| <li>NOTE: This is a candidate for the 8.0 and 9.0 branches.</li> |
| <li>NOTE: This is a candidate for the stable branches.</li> |
| </ul> |
| <h2>Cherry-picking candidates for a stable branch</h2> |
| <p> |
| Please use <code>git cherry-pick -x <commit></code> for cherry-picking a commit |
| from master to a stable branch. |
| </p> |
| <h2>Making a New Mesa Release</h2> |
| <p> |
| These are the instructions for making a new Mesa release. |
| </p> |
| <h3>Get latest source files</h3> |
| <p> |
| Use git to get the latest Mesa files from the git repository, from whatever |
| branch is relevant. |
| </p> |
| <h3>Verify and update version info</h3> |
| <dl> |
| <dt>SConstruct</dt> |
| <dt>Android.common.mk</dt> |
| <dd>PACKAGE_VERSION</dd> |
| <dt>configure.ac</dt> |
| <dd>AC_INIT</dd> |
| </dl> |
| <p> |
| Create a docs/relnotes/x.y.z.html file. |

| <h1>GL Dispatch in Mesa</h1> |
| <p>Several factors combine to make efficient dispatch of OpenGL functions |
| fairly complicated. This document attempts to explain some of the issues |
| and introduce the reader to Mesa's implementation. Readers already familiar |
| with the issues around GL dispatch can safely skip ahead to the <a |
| href="#overview">overview of Mesa's implementation</a>.</p> |
| <h2>1. Complexity of GL Dispatch</h2> |
| <p>Every GL application has at least one object called a GL <em>context</em>. |
| This object, which is an implicit parameter to ever GL function, stores all |
| of the GL related state for the application. Every texture, every buffer |
| object, every enable, and much, much more is stored in the context. Since |
| an application can have more than one context, the context to be used is |
| selected by a window-system dependent function such as |
| <tt>glXMakeContextCurrent</tt>.</p> |
| <p>In environments that implement OpenGL with X-Windows using GLX, every GL |
| function, including the pointers returned by <tt>glXGetProcAddress</tt>, are |
| <em>context independent</em>. This means that no matter what context is |
| currently active, the same <tt>glVertex3fv</tt> function is used.</p> |
| <p>This creates the first bit of dispatch complexity. An application can |
| have two GL contexts. One context is a direct rendering context where |
| function calls are routed directly to a driver loaded within the |
| application's address space. The other context is an indirect rendering |
| context where function calls are converted to GLX protocol and sent to a |
| server. The same <tt>glVertex3fv</tt> has to do the right thing depending |
| on which context is current.</p> |
| <p>Highly optimized drivers or GLX protocol implementations may want to |
| change the behavior of GL functions depending on current state. For |
| example, <tt>glFogCoordf</tt> may operate differently depending on whether |
| or not fog is enabled.</p> |
| <p>In multi-threaded environments, it is possible for each thread to have a |
| differnt GL context current. This means that poor old <tt>glVertex3fv</tt> |
| has to know which GL context is current in the thread where it is being |
| called.</p> |
| <h2 id="overview">2. Overview of Mesa's Implementation</h2> |
| <p>Mesa uses two per-thread pointers. The first pointer stores the address |
| of the context current in the thread, and the second pointer stores the |
| address of the <em>dispatch table</em> associated with that context. The |
| dispatch table stores pointers to functions that actually implement |
| specific GL functions. Each time a new context is made current in a thread, |
| these pointers a updated.</p> |
| <p>The implementation of functions such as <tt>glVertex3fv</tt> becomes |
| conceptually simple:</p> |
| <ul> |
| <li>Fetch the current dispatch table pointer.</li> |
| <li>Fetch the pointer to the real <tt>glVertex3fv</tt> function from the |
| table.</li> |
| <li>Call the real function.</li> |
| </ul> |
| <p>This can be implemented in just a few lines of C code. The file |
| <tt>src/mesa/glapi/glapitemp.h</tt> contains code very similar to this.</p> |
| <blockquote> |
| <table border="1"> |
| <tr><td><pre> |
| void glVertex3f(GLfloat x, GLfloat y, GLfloat z) |
| { |
| const struct _glapi_table * const dispatch = GET_DISPATCH(); |
| (*dispatch->Vertex3f)(x, y, z); |
| }</pre></td></tr> |
| <tr><td>Sample dispatch function</td></tr></table> |
| </blockquote> |
| <p>The problem with this simple implementation is the large amount of |
| overhead that it adds to every GL function call.</p> |
| <p>In a multithreaded environment, a naive implementation of |
| <tt>GET_DISPATCH</tt> involves a call to <tt>pthread_getspecific</tt> or a |
| similar function. Mesa provides a wrapper function called |
| <tt>_glapi_get_dispatch</tt> that is used by default.</p> |
| <h2>3. Optimizations</h2> |
| <p>A number of optimizations have been made over the years to diminish the |
| performance hit imposed by GL dispatch. This section describes these |
| optimizations. The benefits of each optimization and the situations where |
| each can or cannot be used are listed.</p> |
| <h3>3.1. Dual dispatch table pointers</h3> |
| <p>The vast majority of OpenGL applications use the API in a single threaded |
| manner. That is, the application has only one thread that makes calls into |
| the GL. In these cases, not only do the calls to |
| <tt>pthread_getspecific</tt> hurt performance, but they are completely |
| unnecessary! It is possible to detect this common case and avoid these |
| calls.</p> |
| <p>Each time a new dispatch table is set, Mesa examines and records the ID |
| of the executing thread. If the same thread ID is always seen, Mesa knows |
| that the application is, from OpenGL's point of view, single threaded.</p> |
| <p>As long as an application is single threaded, Mesa stores a pointer to |
| the dispatch table in a global variable called <tt>_glapi_Dispatch</tt>. |
| The pointer is also stored in a per-thread location via |
| <tt>pthread_setspecific</tt>. When Mesa detects that an application has |
| become multithreaded, <tt>NULL</tt> is stored in <tt>_glapi_Dispatch</tt>.</p> |
| <p>Using this simple mechanism the dispatch functions can detect the |
| multithreaded case by comparing <tt>_glapi_Dispatch</tt> to <tt>NULL</tt>. |
| The resulting implementation of <tt>GET_DISPATCH</tt> is slightly more |
| complex, but it avoids the expensive <tt>pthread_getspecific</tt> call in |
| the common case.</p> |
| <blockquote> |
| <table border="1"> |
| <tr><td><pre> |
| #define GET_DISPATCH() \ |
| (_glapi_Dispatch != NULL) \ |
| ? _glapi_Dispatch : pthread_getspecific(&_glapi_Dispatch_key) |
| </pre></td></tr> |
| <tr><td>Improved <tt>GET_DISPATCH</tt> Implementation</td></tr></table> |
| </blockquote> |
| <h3>3.2. ELF TLS</h3> |
| <p>Starting with the 2.4.20 Linux kernel, each thread is allocated an area |
| of per-thread, global storage. Variables can be put in this area using some |
| extensions to GCC. By storing the dispatch table pointer in this area, the |
| expensive call to <tt>pthread_getspecific</tt> and the test of |
| <tt>_glapi_Dispatch</tt> can be avoided.</p> |
| <p>The dispatch table pointer is stored in a new variable called |
| <tt>_glapi_tls_Dispatch</tt>. A new variable name is used so that a single |
| libGL can implement both interfaces. This allows the libGL to operate with |
| direct rendering drivers that use either interface. Once the pointer is |
| properly declared, <tt>GET_DISPACH</tt> becomes a simple variable |
| reference.</p> |
| <blockquote> |
| <table border="1"> |
| <tr><td><pre> |
| extern __thread struct _glapi_table *_glapi_tls_Dispatch |
| __attribute__((tls_model("initial-exec"))); |
| #define GET_DISPATCH() _glapi_tls_Dispatch |
| </pre></td></tr> |
| <tr><td>TLS <tt>GET_DISPATCH</tt> Implementation</td></tr></table> |
| </blockquote> |
| <p>Use of this path is controlled by the preprocessor define |
| <tt>GLX_USE_TLS</tt>. Any platform capable of using TLS should use this as |
| the default dispatch method.</p> |
| <h3>3.3. Assembly Language Dispatch Stubs</h3> |
| <p>Many platforms has difficulty properly optimizing the tail-call in the |
| dispatch stubs. Platforms like x86 that pass parameters on the stack seem |
| to have even more difficulty optimizing these routines. All of the dispatch |
| routines are very short, and it is trivial to create optimal assembly |
| language versions. The amount of optimization provided by using assembly |
| stubs varies from platform to platform and application to application. |
| However, by using the assembly stubs, many platforms can use an additional |
| space optimization (see <a href="#fixedsize">below</a>).</p> |
| <p>The biggest hurdle to creating assembly stubs is handling the various |
| ways that the dispatch table pointer can be accessed. There are four |
| different methods that can be used:</p> |
| <ol> |
| <li>Using <tt>_glapi_Dispatch</tt> directly in builds for non-multithreaded |
| environments.</li> |
| <li>Using <tt>_glapi_Dispatch</tt> and <tt>_glapi_get_dispatch</tt> in |
| multithreaded environments.</li> |
| <li>Using <tt>_glapi_Dispatch</tt> and <tt>pthread_getspecific</tt> in |
| multithreaded environments.</li> |
| <li>Using <tt>_glapi_tls_Dispatch</tt> directly in TLS enabled |
| multithreaded environments.</li> |
| </ol> |
| <p>People wishing to implement assembly stubs for new platforms should focus |
| on #4 if the new platform supports TLS. Otherwise, implement #2 followed by |
| #3. Environments that do not support multithreading are uncommon and not |
| terribly relevant.</p> |
| <p>Selection of the dispatch table pointer access method is controlled by a |
| few preprocessor defines.</p> |
| <ul> |
| <li>If <tt>GLX_USE_TLS</tt> is defined, method #4 is used.</li> |
| <li>If <tt>HAVE_PTHREAD</tt> is defined, method #3 is used.</li> |
| <li>If <tt>WIN32_THREADS</tt> is defined, method #2 is used.</li> |
| <li>If none of the preceeding are defined, method #1 is used.</li> |
| </ul> |
| <p>Two different techniques are used to handle the various different cases. |
| On x86 and SPARC, a macro called <tt>GL_STUB</tt> is used. In the preamble |
| of the assembly source file different implementations of the macro are |
| selected based on the defined preprocessor variables. The assmebly code |
| then consists of a series of invocations of the macros such as: |
| <blockquote> |
| <table border="1"> |
| <tr><td><pre> |
| GL_STUB(Color3fv, _gloffset_Color3fv) |
| </pre></td></tr> |
| <tr><td>SPARC Assembly Implementation of <tt>glColor3fv</tt></td></tr></table> |
| </blockquote> |
| <p>The benefit of this technique is that changes to the calling pattern |
| (i.e., addition of a new dispatch table pointer access method) require fewer |
| changed lines in the assembly code.</p> |
| <p>However, this technique can only be used on platforms where the function |
| implementation does not change based on the parameters passed to the |
| function. For example, since x86 passes all parameters on the stack, no |
| additional code is needed to save and restore function parameters around a |
| call to <tt>pthread_getspecific</tt>. Since x86-64 passes parameters in |
| registers, varying amounts of code needs to be inserted around the call to |
| <tt>pthread_getspecific</tt> to save and restore the GL function's |
| parameters.</p> |
| <p>The other technique, used by platforms like x86-64 that cannot use the |
| first technique, is to insert <tt>#ifdef</tt> within the assembly |
| implementation of each function. This makes the assembly file considerably |
| larger (e.g., 29,332 lines for <tt>glapi_x86-64.S</tt> versus 1,155 lines for |
| <tt>glapi_x86.S</tt>) and causes simple changes to the function |
| implementation to generate many lines of diffs. Since the assmebly files |
| are typically generated by scripts (see <a href="#autogen">below</a>), this |
| isn't a significant problem.</p> |
| <p>Once a new assembly file is created, it must be inserted in the build |
| system. There are two steps to this. The file must first be added to |
| <tt>src/mesa/sources</tt>. That gets the file built and linked. The second |
| step is to add the correct <tt>#ifdef</tt> magic to |
| <tt>src/mesa/glapi/glapi_dispatch.c</tt> to prevent the C version of the |
| dispatch functions from being built.</p> |
| <h3 id="fixedsize">3.4. Fixed-Length Dispatch Stubs</h3> |
| <p>To implement <tt>glXGetProcAddress</tt>, Mesa stores a table that |
| associates function names with pointers to those functions. This table is |
| stored in <tt>src/mesa/glapi/glprocs.h</tt>. For different reasons on |
| different platforms, storing all of those pointers is inefficient. On most |
| platforms, including all known platforms that support TLS, we can avoid this |
| added overhead.</p> |
| <p>If the assembly stubs are all the same size, the pointer need not be |
| stored for every function. The location of the function can instead be |
| calculated by multiplying the size of the dispatch stub by the offset of the |
| function in the table. This value is then added to the address of the first |
| dispatch stub.</p> |
| <p>This path is activated by adding the correct <tt>#ifdef</tt> magic to |
| <tt>src/mesa/glapi/glapi.c</tt> just before <tt>glprocs.h</tt> is |
| included.</p> |

| <h1>Mesa EGL</h1> |
| <p>The current version of EGL in Mesa implements EGL 1.4. More information |
| about EGL can be found at |
| <a href="http://www.khronos.org/egl/"> |
| http://www.khronos.org/egl/</a>.</p> |
| <p>The Mesa's implementation of EGL uses a driver architecture. The main |
| library (<code>libEGL</code>) is window system neutral. It provides the EGL |
| API entry points and helper functions for use by the drivers. Drivers are |
| dynamically loaded by the main library and most of the EGL API calls are |
| directly dispatched to the drivers.</p> |
| <p>The driver in use decides the window system to support.</p> |
| <h2>Build EGL</h2> |
| <ol> |
| <li> |
| <p>Run <code>configure</code> with the desired client APIs and enable |
| the driver for your hardware. For example</p> |
| <pre> |
| $ ./configure --enable-gles1 --enable-gles2 \ |
| --with-dri-drivers=... \ |
| --with-gallium-drivers=... |
| </pre> |
| <p>The main library and OpenGL is enabled by default. The first two options |
| above enables <a href="opengles.html">OpenGL ES 1.x and 2.x</a>. The last two |
| options enables the listed classic and and Gallium drivers respectively.</p> |
| </li> |
| <li>Build and install Mesa as usual.</li> |
| </ol> |
| <p>In the given example, it will build and install <code>libEGL</code>, |
| <code>libGL</code>, <code>libGLESv1_CM</code>, <code>libGLESv2</code>, and one |
| or more EGL drivers.</p> |
| <h3>Configure Options</h3> |
| <p>There are several options that control the build of EGL at configuration |
| time</p> |
| <dl> |
| <dt><code>--enable-egl</code></dt> |
| <dd> |
| <p>By default, EGL is enabled. When disabled, the main library and the drivers |
| will not be built.</p> |
| </dd> |
| <dt><code>--with-egl-driver-dir</code></dt> |
| <dd> |
| <p>The directory EGL drivers should be installed to. If not specified, EGL |
| drivers will be installed to <code>${libdir}/egl</code>.</p> |
| </dd> |
| <dt><code>--enable-gallium-egl</code></dt> |
| <dd> |
| <p>Enable the optional <code>egl_gallium</code> driver.</p> |
| </dd> |
| <dt><code>--with-egl-platforms</code></dt> |
| <dd> |
| <p>List the platforms (window systems) to support. Its argument is a comma |
| seprated string such as <code>--with-egl-platforms=x11,drm</code>. It decides |
| the platforms a driver may support. The first listed platform is also used by |
| the main library to decide the native platform: the platform the EGL native |
| types such as <code>EGLNativeDisplayType</code> or |
| <code>EGLNativeWindowType</code> defined for.</p> |
| <p>The available platforms are <code>x11</code>, <code>drm</code>, |
| <code>fbdev</code>, and <code>gdi</code>. The <code>gdi</code> platform can |
| only be built with SCons. Unless for special needs, the build system should |
| select the right platforms automatically.</p> |
| </dd> |
| <dt><code>--enable-gles1</code></dt> |
| <dt><code>--enable-gles2</code></dt> |
| <dd> |
| <p>These options enable OpenGL ES support in OpenGL. The result is one big |
| internal library that supports multiple APIs.</p> |
| </dd> |
| <dt><code>--enable-shared-glapi</code></dt> |
| <dd> |
| <p>By default, <code>libGL</code> has its own copy of <code>libglapi</code>. |
| This options makes <code>libGL</code> use the shared <code>libglapi</code>. This |
| is required if applications mix OpenGL and OpenGL ES.</p> |
| </dd> |
| <dt><code>--enable-openvg</code></dt> |
| <dd> |
| <p>OpenVG must be explicitly enabled by this option.</p> |
| </dd> |
| </dl> |
| <h2>Use EGL</h2> |
| <h3>Demos</h3> |
| <p>There are demos for the client APIs supported by EGL. They can be found in |
| mesa/demos repository.</p> |
| <h3>Environment Variables</h3> |
| <p>There are several environment variables that control the behavior of EGL at |
| runtime</p> |
| <dl> |
| <dt><code>EGL_DRIVERS_PATH</code></dt> |
| <dd> |
| <p>By default, the main library will look for drivers in the directory where |
| the drivers are installed to. This variable specifies a list of |
| colon-separated directories where the main library will look for drivers, in |
| addition to the default directory. This variable is ignored for setuid/setgid |
| binaries.</p> |
| <p>This variable is usually set to test an uninstalled build. For example, one |
| may set</p> |
| <pre> |
| $ export LD_LIBRARY_PATH=$mesa/lib |
| $ export EGL_DRIVERS_PATH=$mesa/lib/egl |
| </pre> |
| <p>to test a build without installation</p> |
| </dd> |
| <dt><code>EGL_DRIVER</code></dt> |
| <dd> |
| <p>This variable specifies a full path to or the name of an EGL driver. It |
| forces the specified EGL driver to be loaded. It comes in handy when one wants |
| to test a specific driver. This variable is ignored for setuid/setgid |
| binaries.</p> |
| </dd> |
| <dt><code>EGL_PLATFORM</code></dt> |
| <dd> |
| <p>This variable specifies the native platform. The valid values are the same |
| as those for <code>--with-egl-platforms</code>. When the variable is not set, |
| the main library uses the first platform listed in |
| <code>--with-egl-platforms</code> as the native platform.</p> |
| <p>Extensions like <code>EGL_MESA_drm_display</code> define new functions to |
| create displays for non-native platforms. These extensions are usually used by |
| applications that support non-native platforms. Setting this variable is |
| probably required only for some of the demos found in mesa/demo repository.</p> |
| </dd> |
| <dt><code>EGL_LOG_LEVEL</code></dt> |
| <dd> |
| <p>This changes the log level of the main library and the drivers. The valid |
| values are: <code>debug</code>, <code>info</code>, <code>warning</code>, and |
| <code>fatal</code>.</p> |
| </dd> |
| <dt><code>EGL_SOFTWARE</code></dt> |
| <dd> |
| <p>For drivers that support both hardware and software rendering, setting this |
| variable to true forces the use of software rendering.</p> |
| </dd> |
| </dl> |
| <h2>EGL Drivers</h2> |
| <dl> |
| <dt><code>egl_dri2</code></dt> |
| <dd> |
| <p>This driver supports both <code>x11</code> and <code>drm</code> platforms. |
| It functions as a DRI driver loader. For <code>x11</code> support, it talks to |
| the X server directly using (XCB-)DRI2 protocol.</p> |
| <p>This driver can share DRI drivers with <code>libGL</code>.</p> |
| </dd> |
| <dt><code>egl_gallium</code></dt> |
| <dd> |
| <p>This driver is based on Gallium3D. It supports all rendering APIs and |
| hardwares supported by Gallium3D. It is the only driver that supports OpenVG. |
| The supported platforms are X11, DRM, FBDEV, and GDI.</p> |
| <p>This driver comes with its own hardware drivers |
| (<code>pipe_<hw></code>) and client API modules |
| (<code>st_<api></code>).</p> |
| </dd> |
| <dt><code>egl_glx</code></dt> |
| <dd> |
| <p>This driver provides a wrapper to GLX. It uses exclusively GLX to implement |
| the EGL API. It supports both direct and indirect rendering when the GLX does. |
| It is accelerated when the GLX is. As such, it cannot provide functions that |
| is not available in GLX or GLX extensions.</p> |
| </dd> |
| </dl> |
| <h2>Packaging</h2> |
| <p>The ABI between the main library and its drivers are not stable. Nor is |
| there a plan to stabilize it at the moment. Of the EGL drivers, |
| <code>egl_gallium</code> has its own hardware drivers and client API modules. |
| They are considered internal to <code>egl_gallium</code> and there is also no |
| stable ABI between them. These should be kept in mind when packaging for |
| distribution.</p> |
| <p>Generally, <code>egl_dri2</code> is preferred over <code>egl_gallium</code> |
| when the system already has DRI drivers. As <code>egl_gallium</code> is loaded |
| before <code>egl_dri2</code> when both are available, <code>egl_gallium</code> |
| is disabled by default.</p> |
| <h2>Developers</h2> |
| <p>The sources of the main library and the classic drivers can be found at |
| <code>src/egl/</code>. The sources of the <code>egl</code> state tracker can |
| be found at <code>src/gallium/state_trackers/egl/</code>.</p> |
| <p>The suggested way to learn to write a EGL driver is to see how other drivers |
| are written. <code>egl_glx</code> should be a good reference. It works in any |
| environment that has GLX support, and it is simpler than most drivers.</p> |
| <h3>Lifetime of Display Resources</h3> |
| <p>Contexts and surfaces are examples of display resources. They might live |
| longer than the display that creates them.</p> |
| <p>In EGL, when a display is terminated through <code>eglTerminate</code>, all |
| display resources should be destroyed. Similarly, when a thread is released |
| throught <code>eglReleaseThread</code>, all current display resources should be |
| released. Another way to destory or release resources is through functions |
| such as <code>eglDestroySurface</code> or <code>eglMakeCurrent</code>.</p> |
| <p>When a resource that is current to some thread is destroyed, the resource |
| should not be destroyed immediately. EGL requires the resource to live until |
| it is no longer current. A driver usually calls |
| <code>eglIs<Resource>Bound</code> to check if a resource is bound |
| (current) to any thread in the destroy callbacks. If it is still bound, the |
| resource is not destroyed.</p> |
| <p>The main library will mark destroyed current resources as unlinked. In a |
| driver's <code>MakeCurrent</code> callback, |
| <code>eglIs<Resource>Linked</code> can then be called to check if a newly |
| released resource is linked to a display. If it is not, the last reference to |
| the resource is removed and the driver should destroy the resource. But it |
| should be careful here because <code>MakeCurrent</code> might be called with an |
| uninitialized display.</p> |
| <p>This is the only mechanism provided by the main library to help manage the |
| resources. The drivers are responsible to the correct behavior as defined by |
| EGL.</p> |
| <h3><code>EGL_RENDER_BUFFER</code></h3> |
| <p>In EGL, the color buffer a context should try to render to is decided by the |
| binding surface. It should try to render to the front buffer if the binding |
| surface has <code>EGL_RENDER_BUFFER</code> set to |
| <code>EGL_SINGLE_BUFFER</code>; If the same context is later bound to a |
| surface with <code>EGL_RENDER_BUFFER</code> set to |
| <code>EGL_BACK_BUFFER</code>, the context should try to render to the back |
| buffer. However, the context is allowed to make the final decision as to which |
| color buffer it wants to or is able to render to.</p> |
| <p>For pbuffer surfaces, the render buffer is always |
| <code>EGL_BACK_BUFFER</code>. And for pixmap surfaces, the render buffer is |
| always <code>EGL_SINGLE_BUFFER</code>. Unlike window surfaces, EGL spec |
| requires their <code>EGL_RENDER_BUFFER</code> values to be honored. As a |
| result, a driver should never set <code>EGL_PIXMAP_BIT</code> or |
| <code>EGL_PBUFFER_BIT</code> bits of a config if the contexts created with the |
| config won't be able to honor the <code>EGL_RENDER_BUFFER</code> of pixmap or |
| pbuffer surfaces.</p> |
| <p>It should also be noted that pixmap and pbuffer surfaces are assumed to be |
| single-buffered, in that <code>eglSwapBuffers</code> has no effect on them. It |
| is desirable that a driver allocates a private color buffer for each pbuffer |
| surface created. If the window system the driver supports has native pbuffers, |
| or if the native pixmaps have more than one color buffers, the driver should |
| carefully attach the native color buffers to the EGL surfaces, re-route them if |
| required.</p> |
| <p>There is no defined behavior as to, for example, how |
| <code>glDrawBuffer</code> interacts with <code>EGL_RENDER_BUFFER</code>. Right |
| now, it is desired that the draw buffer in a client API be fixed for pixmap and |
| pbuffer surfaces. Therefore, the driver is responsible to guarantee that the |
| client API renders to the specified render buffer for pixmap and pbuffer |
| surfaces.</p> |
| <h3><code>EGLDisplay</code> Mutex</h3> |
| The <code>EGLDisplay</code> will be locked before calling any of the dispatch |
| functions (well, except for GetProcAddress which does not take an |
| <code>EGLDisplay</code>). This guarantees that the same dispatch function will |
| not be called with the sample display at the same time. If a driver has access |
| to an <code>EGLDisplay</code> without going through the EGL APIs, the driver |
| should as well lock the display before using it. |

| <div class="content"> |
| <h1>Environment Variables</h1> |
| <p> |
| Normally, no environment variables need to be set. Most of the environment |
| variables used by Mesa/Gallium are for debugging purposes, but they can |
| sometimes be useful for debugging end-user issues. |
| </p> |
| <h2>LibGL environment variables</h2> |
| <ul> |
| <li>LIBGL_DEBUG - If defined debug information will be printed to stderr. |
| If set to 'verbose' additional information will be printed. |
| <li>LIBGL_DRIVERS_PATH - colon-separated list of paths to search for DRI drivers |
| <li>LIBGL_ALWAYS_INDIRECT - forces an indirect rendering context/connection. |
| <li>LIBGL_ALWAYS_SOFTWARE - if set, always use software rendering |
| <li>LIBGL_NO_DRAWARRAYS - if set do not use DrawArrays GLX protocol (for debugging) |
| <li>LIBGL_SHOW_FPS - print framerate to stdout based on the number of glXSwapBuffers |
| calls per second. |
| </ul> |
| <h2>Core Mesa environment variables</h2> |
| <ul> |
| <li>MESA_NO_ASM - if set, disables all assembly language optimizations |
| <li>MESA_NO_MMX - if set, disables Intel MMX optimizations |
| <li>MESA_NO_3DNOW - if set, disables AMD 3DNow! optimizations |
| <li>MESA_NO_SSE - if set, disables Intel SSE optimizations |
| <li>MESA_DEBUG - if set, error messages are printed to stderr. For example, |
| if the application generates a GL_INVALID_ENUM error, a corresponding error |
| message indicating where the error occured, and possibly why, will be |
| printed to stderr.<br> |
| If the value of MESA_DEBUG is 'FP' floating point arithmetic errors will |
| generate exceptions. |
| <li>MESA_LOG_FILE - specifies a file name for logging all errors, warnings, |
| etc., rather than stderr |
| <li>MESA_TEX_PROG - if set, implement conventional texture env modes with |
| fragment programs (intended for developers only) |
| <li>MESA_TNL_PROG - if set, implement conventional vertex transformation |
| operations with vertex programs (intended for developers only). |
| Setting this variable automatically sets the MESA_TEX_PROG variable as well. |
| <li>MESA_EXTENSION_OVERRIDE - can be used to enable/disable extensions. |
| A value such as "GL_EXT_foo -GL_EXT_bar" will enable the GL_EXT_foo extension |
| and disable the GL_EXT_bar extension. |
| <li>MESA_EXTENSION_MAX_YEAR - The GL_EXTENSIONS string returned by Mesa is sorted |
| by extension year. |
| If this variable is set to year X, only extensions defined on or before year |
| X will be reported. |
| This is to work-around a bug in some games where the extension string is |
| copied into a fixed-size buffer without truncating. |
| If the extension string is too long, the buffer overrun can cause the game |
| to crash. |
| This is a work-around for that. |
| <li>MESA_GL_VERSION_OVERRIDE - changes the value returned by |
| glGetString(GL_VERSION) and possibly the GL API type. |
| <ul> |
| <li> The format should be MAJOR.MINOR[FC] |
| <li> FC is an optional suffix that indicates a forward compatible context. |
| This is only valid for versions >= 3.0. |
| <li> GL versions < 3.0 are set to a compatibility (non-Core) profile |
| <li> GL versions = 3.0, see below |
| <li> GL versions > 3.0 are set to a Core profile |
| <li> Examples: 2.1, 3.0, 3.0FC, 3.1, 3.1FC |
| <ul> |
| <li> 2.1 - select a compatibility (non-Core) profile with GL version 2.1 |
| <li> 3.0 - select a compatibility (non-Core) profile with GL version 3.0 |
| <li> 3.0FC - select a Core+Forward Compatible profile with GL version 3.0 |
| <li> 3.1 - select a Core profile with GL version 3.1 |
| <li> 3.1FC - select a Core+Forward Compatible profile with GL version 3.1 |
| </ul> |
| <li> Mesa may not really implement all the features of the given version. |
| (for developers only) |
| </ul> |
| <li>MESA_GLSL_VERSION_OVERRIDE - changes the value returned by |
| glGetString(GL_SHADING_LANGUAGE_VERSION). Valid values are integers, such as |
| "130". Mesa will not really implement all the features of the given language version |
| if it's higher than what's normally reported. (for developers only) |
| <li>MESA_GLSL - <a href="shading.html#envvars">shading language compiler options</a> |
| </ul> |
| <h2>Mesa Xlib driver environment variables</h2> |
| <p> |
| The following are only applicable to the Mesa Xlib software driver. |
| See the <a href="xlibdriver.html">Xlib software driver page</a> for details. |
| </p> |

| <li>MESA_CI_VISUAL - specifies the X visual and depth for CI mode |
| <li>MESA_BACK_BUFFER - specifies how to implement the back color buffer, |
| either "pixmap" or "ximage" |
| <li>MESA_GAMMA - gamma correction coefficients for red, green, blue channels |

| <li>MESA_GLX_FORCE_CI - if set, force GLX to treat 8bpp visuals as CI visuals |
| <li>MESA_GLX_FORCE_ALPHA - if set, forces RGB windows to have an alpha channel. |
| <li>MESA_GLX_DEPTH_BITS - specifies default number of bits for depth buffer. |
| <li>MESA_GLX_ALPHA_BITS - specifies default number of bits for alpha channel. |
| </ul> |
| <h2>i945/i965 driver environment variables (non-Gallium)</h2> |
| <ul> |
| <li>INTEL_STRICT_CONFORMANCE - if set to 1, enable sw fallbacks to improve |
| OpenGL conformance. If set to 2, always use software rendering. |
| <li>INTEL_NO_BLIT - if set, disable hardware-accelerated glBitmap, |
| glCopyPixels, glDrawPixels. |
| </ul> |
| <h2>Radeon driver environment variables (radeon, r200, and r300g)</h2> |
| <ul> |
| <li>RADEON_NO_TCL - if set, disable hardware-accelerated Transform/Clip/Lighting. |
| </ul> |
| <h2>EGL environment variables</h2> |
| <p> |
| Mesa EGL supports different sets of environment variables. See the |
| <a href="egl.html">Mesa EGL</a> page for the details. |
| </p> |
| <h2>Gallium environment variables</h2> |
| <ul> |
| <li>GALLIUM_HUD - draws various information on the screen, like framerate, |
| cpu load, driver statistics, performance counters, etc. |
| Set GALLIUM_HUD=help and run e.g. glxgears for more info. |

| rather than stderr. |
| <li>GALLIUM_PRINT_OPTIONS - if non-zero, print all the Gallium environment |
| variables which are used, and their current values. |
| <li>GALLIUM_DUMP_CPU - if non-zero, print information about the CPU on start-up |
| <li>TGSI_PRINT_SANITY - if set, do extra sanity checking on TGSI shaders and |
| print any errors to stderr. |
| <LI>DRAW_FSE - ??? |
| <LI>DRAW_NO_FSE - ??? |
| <li>DRAW_USE_LLVM - if set to zero, the draw module will not use LLVM to execute |
| shaders, vertex fetch, etc. |
| <li>ST_DEBUG - controls debug output from the Mesa/Gallium state tracker. |
| Setting to "tgsi", for example, will print all the TGSI shaders. |
| See src/mesa/state_tracker/st_debug.c for other options. |
| </ul> |
| <h3>Softpipe driver environment variables</h3> |
| <ul> |
| <li>SOFTPIPE_DUMP_FS - if set, the softpipe driver will print fragment shaders |

| <li>LP_DEBUG - a comma-separated list of debug options is acceptec. See the |
| source code for details. |
| <li>LP_PERF - a comma-separated list of options to selectively no-op various |
| parts of the driver. See the source code for details. |
| <li>LP_NUM_THREADS - an integer indicating how many threads to use for rendering. |

| cores present. |
| </ul> |
| <h3>VMware SVGA driver environment variables</h3> |
| <ul> |
| <li>SVGA_FORCE_SWTNL - force use of software vertex transformation |
| <li>SVGA_NO_SWTNL - don't allow software vertex transformation fallbacks |
| (will often result in incorrect rendering). |
| <li>SVGA_DEBUG - for dumping shaders, constant buffers, etc. See the code |
| for details. |
| <li>See the driver code for other, lesser-used variables. |
| </ul> |
| <p> |
| Other Gallium drivers have their own environment variables. These may change |
| frequently so the source code should be consulted for details. |

| <h1 id="part1">1. High-level Questions and Answers</h1> |
| <h2>1.1 What is Mesa?</h2> |
| <p> |
| Mesa is an open-source implementation of the OpenGL specification. |
| OpenGL is a programming library for writing interactive 3D applications. |
| See the <a href="http://www.opengl.org/">OpenGL website</a> for more |
| information. |
| </p> |
| <p> |
| Mesa 9.x supports the OpenGL 3.1 specification. |
| </p> |
| <h2>1.2 Does Mesa support/use graphics hardware?</h2> |
| <p> |
| Yes. Specifically, Mesa serves as the OpenGL core for the open-source DRI |
| drivers for X.org. |
| </p> |
| <ul> |
| <li>See the <a href="http://dri.freedesktop.org/">DRI website</a> |
| for more information.</li> |
| <li>See <a href="http://intellinuxgraphics.org">intellinuxgraphics.org</a> |
| for more information about Intel drivers.</li> |
| <li>See <a href="http://nouveau.freedesktop.org">nouveau.freedesktop.org</a> |
| for more information about Nouveau drivers.</li> |
| <li>See <a href="http://www.x.org/wiki/RadeonFeature">www.x.org/wiki/RadeonFeature</a> |
| for more information about Radeon drivers.</li> |
| </ul> |
| <h2>1.3 What purpose does Mesa serve today?</h2> |
| <p> |
| Hardware-accelerated OpenGL implementations are available for most popular |
| operating systems today. |
| Still, Mesa serves at least these purposes: |
| </p> |
| <ul> |
| <li>Mesa is used as the core of the open-source X.org DRI |
| hardware drivers. |
| </li> |
| <li>Mesa is quite portable and allows OpenGL to be used on systems |
| that have no other OpenGL solution. |
| </li> |
| <li>Software rendering with Mesa serves as a reference for validating the |
| hardware drivers. |
| </li> |
| <li>A software implementation of OpenGL is useful for experimentation, |
| such as testing new rendering techniques. |
| </li> |
| <li>Mesa can render images with deep color channels: 16-bit integer |
| and 32-bit floating point color channels are supported. |
| This capability is only now appearing in hardware. |
| </li> |
| <li>Mesa's internal limits (max lights, clip planes, texture size, etc) can be |
| changed for special needs (hardware limits are hard to overcome). |
| </li> |
| </ul> |
| <h2>1.4 What's the difference between "Stand-Alone" Mesa and the DRI drivers?</h2> |
| <p> |
| <em>Stand-alone Mesa</em> is the original incarnation of Mesa. |
| On systems running the X Window System it does all its rendering through |
| the Xlib API: |
| </p> |
| <ul> |
| <li>The GLX API is supported, but it's really just an emulation of the |
| real thing. |
| <li>The GLX wire protocol is not supported and there's no OpenGL extension |
| loaded by the X server. |
| <li>There is no hardware acceleration. |
| <li>The OpenGL library, libGL.so, contains everything (the programming API, |
| the GLX functions and all the rendering code). |
| </ul> |
| <p> |
| Alternately, Mesa acts as the core for a number of OpenGL hardware drivers |
| within the DRI (Direct Rendering Infrastructure): |
| <ul> |
| <li>The libGL.so library provides the GL and GLX API functions, a GLX |
| protocol encoder, and a device driver loader. |
| <li>The device driver modules (such as r200_dri.so) contain a built-in |
| copy of the core Mesa code. |
| <li>The X server loads the GLX module. |
| The GLX module decodes incoming GLX protocol and dispatches the commands |
| to a rendering module. |
| For the DRI, this module is basically a software Mesa renderer. |
| </ul> |
| <h2>1.5 How do I upgrade my DRI installation to use a new Mesa release?</h2> |
| <p> |
| This wasn't easy in the past. |
| Now, the DRI drivers are included in the Mesa tree and can be compiled |
| separately from the X server. |
| Just follow the Mesa <a href="install.html">compilation instructions</a>. |
| </p> |
| <h2>1.6 Are there other open-source implementations of OpenGL?</h2> |
| <p> |
| Yes, SGI's <a href="http://oss.sgi.com/projects/ogl-sample/index.html"> |
| OpenGL Sample Implemenation (SI)</a> is available. |
| The SI was written during the time that OpenGL was originally designed. |
| Unfortunately, development of the SI has stagnated. |
| Mesa is much more up to date with modern features and extensions. |

| <h1 id="part2">2. Compilation and Installation Problems</h1> |
| <h2>2.1 What's the easiest way to install Mesa?</h2> |
| <p> |
| If you're using a Linux-based system, your distro CD most likely already |
| has Mesa packages (like RPM or DEB) which you can easily install. |
| </p> |
| <h2>2.2 I get undefined symbols such as bgnpolygon, v3f, etc...</h2> |
| <p> |
| You're application is written in IRIS GL, not OpenGL. |
| IRIS GL was the predecessor to OpenGL and is a different thing (almost) |
| entirely. |
| Mesa's not the solution. |
| </p> |
| <h2>2.3 Where is the GLUT library?</h2> |
| <p> |
| GLUT (OpenGL Utility Toolkit) is no longer in the separate MesaGLUT-x.y.z.tar.gz file. |
| If you don't already have GLUT installed, you should grab |
| <a href="http://freeglut.sourceforge.net/">freeglut</a>. |
| </p> |
| <h2>2.4 Where is the GLw library?</h2> |
| <p> |
| GLw (OpenGL widget library) is now available from a separate <a href="http://cgit.freedesktop.org/mesa/glw/">git repository</a>. Unless you're using very old Xt/Motif applications with OpenGL, you shouldn't need it. |
| </p> |
| <h2>2.5 What's the proper place for the libraries and headers?</h2> |
| <p> |
| On Linux-based systems you'll want to follow the |
| <a href="http://oss.sgi.com/projects/ogl-sample/ABI/index.html">Linux ABI</a> standard. |
| Basically you'll want the following: |
| </p> |
| <ul> |
| <li>/usr/include/GL/gl.h - the main OpenGL header |
| </li><li>/usr/include/GL/glu.h - the OpenGL GLU (utility) header |
| </li><li>/usr/include/GL/glx.h - the OpenGL GLX header |
| </li><li>/usr/include/GL/glext.h - the OpenGL extensions header |
| </li><li>/usr/include/GL/glxext.h - the OpenGL GLX extensions header |
| </li><li>/usr/include/GL/osmesa.h - the Mesa off-screen rendering header |
| </li><li>/usr/lib/libGL.so - a symlink to libGL.so.1 |
| </li><li>/usr/lib/libGL.so.1 - a symlink to libGL.so.1.xyz |
| </li><li>/usr/lib/libGL.so.xyz - the actual OpenGL/Mesa library. xyz denotes the |
| Mesa version number. |
| </li></ul> |
| <p> |
| When configuring Mesa, there are three autoconf options that affect the install |
| location that you should take care with: <code>--prefix</code>, |
| <code>--libdir</code>, and <code>--with-dri-driverdir</code>. To install Mesa |
| into the system location where it will be available for all programs to use, set |
| <code>--prefix=/usr</code>. Set <code>--libdir</code> to where your Linux |
| distribution installs system libraries, usually either <code>/usr/lib</code> or |
| <code>/usr/lib64</code>. Set <code>--with-dri-driverdir</code> to the directory |
| where your Linux distribution installs DRI drivers. To find your system's DRI |
| driver directory, try executing <code>find /usr -type d -name dri</code>. For |
| example, if the <code>find</code> command listed <code>/usr/lib64/dri</code>, |
| then set <code>--with-dri-driverdir=/usr/lib64/dri</code>. |
| </p> |
| <p> |
| After determining the correct values for the install location, configure Mesa |
| with <code>./configure --prefix=/usr --libdir=xxx --with-dri-driverdir=xxx</code> |
| and then install with <code>sudo make install</code>. |
| </p> |
| <br> |
| <br> |
| <h1 id="part3">3. Runtime / Rendering Problems</h1> |
| <h2>3.1 Rendering is slow / why isn't my graphics hardware being used?</h2> |
| <p> |
| If Mesa can't use its hardware accelerated drivers it falls back on one of its software renderers. |
| (eg. classic swrast, softpipe or llvmpipe) |
| </p> |
| <p> |
| You can run the <code>glxinfo</code> program to learn about your OpenGL |
| library. |
| Look for the <code>OpenGL vendor</code> and <code>OpenGL renderer</code> values. |
| That will identify who's OpenGL library with which driver you're using and what sort of |
| hardware it has detected. |
| </p> |
| <p> |
| If you're using a hardware accelerated driver you want <code>direct rendering: Yes</code>. |
| </p> |
| <p> |
| If your DRI-based driver isn't working, go to the |
| <a href="http://dri.freedesktop.org/">DRI website</a> for trouble-shooting information. |
| </p> |
| <h2>3.2 I'm seeing errors in depth (Z) buffering. Why?</h2> |
| <p> |
| Make sure the ratio of the far to near clipping planes isn't too great. |
| Look |
| <a href="http://www.opengl.org/resources/faq/technical/depthbuffer.htm#0040">here</a> |
| for details. |
| </p> |
| <p> |
| Mesa uses a 16-bit depth buffer by default which is smaller and faster |
| to clear than a 32-bit buffer but not as accurate. |
| If you need a deeper you can modify the parameters to |
| <code> glXChooseVisual</code> in your code. |
| </p> |
| <h2>3.3 Why Isn't depth buffering working at all?</h2> |
| <p> |
| Be sure you're requesting a depth buffered-visual. If you set the MESA_DEBUG |
| environment variable it will warn you about trying to enable depth testing |
| when you don't have a depth buffer. |
| </p> |
| <p>Specifically, make sure <code>glutInitDisplayMode</code> is being called |
| with <code>GLUT_DEPTH</code> or <code>glXChooseVisual</code> is being |
| called with a non-zero value for GLX_DEPTH_SIZE. |
| </p> |
| <p>This discussion applies to stencil buffers, accumulation buffers and |
| alpha channels too. |
| </p> |
| <h2>3.4 Why does glGetString() always return NULL?</h2> |
| <p> |
| Be sure you have an active/current OpenGL rendering context before |
| calling glGetString. |
| </p> |
| <h2>3.5 GL_POINTS and GL_LINES don't touch the right pixels</h2> |
| <p> |
| If you're trying to draw a filled region by using GL_POINTS or GL_LINES |
| and seeing holes or gaps it's because of a float-to-int rounding problem. |
| But this is not a bug. |
| See Appendix H of the OpenGL Programming Guide - "OpenGL Correctness Tips". |
| Basically, applying a translation of (0.375, 0.375, 0.0) to your coordinates |
| will fix the problem. |
| </p> |
| <h2>3.6 How can I change the maximum framebuffer size in Mesa's |
| <tt>swrast</tt> backend?</h2> |
| <p> |
| These can be overridden by using the <tt>--with-max-width</tt> and |
| <tt>--with-max-height</tt> options. The two need not be equal. |
| </p><p> |
| Do note that Mesa uses these values to size some internal buffers, |
| so increasing these sizes will cause Mesa to require additional |
| memory. Furthermore, increasing these limits beyond <tt>4096</tt> |
| may introduce rasterization artifacts; see the leading comments in |
| <tt>src/mesa/swrast/s_tritemp.h</tt>. |
| </p> |
| <br> |
| <br> |
| <h1 id="part4">4. Developer Questions</h1> |
| <h2>4.1 How can I contribute?</h2> |
| <p> |
| First, join the <a href="lists.html">mesa-dev mailing list</a>. |
| That's where Mesa development is discussed. |
| </p> |
| <p> |
| The <a href="http://www.opengl.org/documentation"> |
| OpenGL Specification</a> is the bible for OpenGL implemention work. |
| You should read it. |
| </p> |
| <p>Most of the Mesa development work involves implementing new OpenGL |
| extensions, writing hardware drivers (for the DRI), and code optimization. |
| </p> |
| <h2>4.2 How do I write a new device driver?</h2> |
| <p> |
| Unfortunately, writing a device driver isn't easy. |
| It requires detailed understanding of OpenGL, the Mesa code, and your |
| target hardware/operating system. |
| 3D graphics are not simple. |
| </p> |
| <p> |
| The best way to get started is to use an existing driver as your starting |
| point. |
| For a classic hardware driver, the i965 driver is a good example. |
| For a Gallium3D hardware driver, the r300g, r600g and the i915g are good examples. |
| </p> |
| <p>The DRI website has more information about writing hardware drivers. |
| The process isn't well document because the Mesa driver interface changes |
| over time, and we seldome have spare time for writing documentation. |
| That being said, many people have managed to figure out the process. |
| </p> |
| <p> |
| Joining the appropriate mailing lists and asking questions (and searching |
| the archives) is a good way to get information. |
| </p> |
| <h2>4.3 Why isn't GL_EXT_texture_compression_s3tc implemented in Mesa?</h2> |
| <p> |
| The <a href="http://oss.sgi.com/projects/ogl-sample/registry/EXT/texture_compression_s3tc.txt">specification for the extension</a> |
| indicates that there are intellectual property (IP) and/or patent issues |
| to be dealt with. |
| </p> |
| <p>We've been unsucessful in getting a response from S3 (or whoever owns |
| the IP nowadays) to indicate whether or not an open source project can |
| implement the extension (specifically the compression/decompression |
| algorithms). |
| </p> |
| <p> |
| In the mean time, a 3rd party <a href="http://dri.freedesktop.org/wiki/S3TC"> |
| plug-in library</a> is available. |

| <h1>Help Wanted / To-Do List</h1> |
| <p> |
| We can always use more help with the Mesa project. |
| Here are some specific ideas and areas where help would be appreciated: |
| </p> |
| <ol> |
| <li> |
| <b>Driver patching and testing.</b> |
| Patches are often posted to the <a href="http://lists.freedesktop.org/mailman/listinfo/mesa-dev">mesa-dev mailing list</a>, but aren't |
| immediately checked into git because not enough people are testing them. |
| Just applying patches, testing and reporting back is helpful. |
| <li> |
| <b>Driver debugging.</b> |
| There are plenty of open bugs in the <a href="https://bugs.freedesktop.org/describecomponents.cgi?product=Mesa">bug database</a>. |
| <li> |
| <b>Remove aliasing warnings.</b> |
| Enable gcc -Wstrict-aliasing=2 -fstrict-aliasing and track down aliasing |
| issues in the code. |
| <li> |
| <b>Windows driver building, testing and maintenance.</b> |
| Fixing MSVC builds. |
| <li> |
| <b>Contribute more tests to |
| <a href="http://piglit.freedesktop.org/">Piglit</a>.</b> |
| <li> |
| <b>Automatic testing. |
| </b> |
| It would be great if someone would set up an automated system for grabbing |
| the latest Mesa code and run tests (such as piglit) then report issues to |
| the mailing list. |
| </ol> |
| <p> |
| You can find some further To-do lists here: |
| </p> |
| <p> |
| <b>Common To-Do lists:</b> |
| </p> |
| <ul> |
| <li><a href="http://cgit.freedesktop.org/mesa/mesa/tree/docs/GL3.txt"> |
| <b>GL3.txt</b></a> - Status of OpenGL 3.x / 4.x features in Mesa.</li> |
| <li><a href="http://dri.freedesktop.org/wiki/MissingFunctionality"> |
| <b>MissingFunctionality</b></a> - Detailed information about missing OpenGL features.</li> |
| </ul> |
| <p> |
| <b>Driver specific To-Do lists:</b> |
| </p> |
| <ul> |
| <li><a href="http://cgit.freedesktop.org/mesa/mesa/tree/src/gallium/docs/llvm-todo.txt"> |
| <b>LLVMpipe</b></a> - Software driver using LLVM for runtime code generation.</li> |
| <li><a href="http://dri.freedesktop.org/wiki/RadeonsiToDo"> |

| <b>r300g</b></a> - Driver for ATI R300 - R500.</li> |
| <li><a href="http://cgit.freedesktop.org/mesa/mesa/tree/src/gallium/drivers/i915/TODO"> |
| <b>i915g</b></a> - Driver for Intel i915/i945.</li> |
| </ul> |
| <p> |
| If you want to do something new in Mesa, first join the Mesa developer's |
| mailing list. |
| Then post a message to propose what you want to do, just to make sure |
| there's no issues. |
| </p> |
| <p> |
| Anyone is welcome to contribute code to the Mesa project. |
| By doing so, it's assumed that you agree to the code's licensing terms. |
| </p> |
| <p> |
| Finally: |
| </p> |
| <ol> |
| <li>Try to write high-quality code that follows the existing style. |
| <li>Use uniform indentation, write comments, use meaningful identifiers, etc. |
| <li>Test your code thoroughly. Include test programs if appropriate. |
| </ol> |

| <h2>1.1 General</h2> |
| <ul> |
| <li>lex / yacc - for building the GLSL compiler. |
| On Linux systems, flex and bison are used. |
| Versions 2.5.35 and 2.4.1, respectively, (or later) should work. |
| <br> |
| <br> |
| On Windows with MinGW, install flex and bison with: |
| <pre>mingw-get install msys-flex msys-bison</pre> |
| </li> |
| <li>python - Python is needed for building the Gallium components. |
| Version 2.6.4 or later should work. |
| <br> |
| <br> |
| To build OpenGL ES 1.1 and 2.0 you'll also need |
| <a href="http://xmlsoft.org/sources/win32/python/libxml2-python-2.7.7.win32-py2.7.exe">libxml2-python</a>. |
| </li> |
| </ul> |
| <h3 id="prereq-dri">1.2 For DRI and hardware acceleration</h3> |
| <p> |
| The following are required for DRI-based hardware acceleration with Mesa: |
| </p> |
| <ul> |
| <li><a href="http://xorg.freedesktop.org/releases/individual/proto/"> |
| dri2proto</a> version 2.6 or later |
| <li><a href="http://dri.freedesktop.org/libdrm/">libDRM</a> |
| version 2.4.33 or later |
| <li>Xorg server version 1.5 or later |
| <li>Linux 2.6.28 or later |
| </ul> |
| <p> |
| If you're using a fedora distro the following command should install all |
| the needed dependencies: |
| </p> |
| <pre> |
| sudo yum install flex bison imake libtool xorg-x11-proto-devel libdrm-devel \ |
| gcc-c++ xorg-x11-server-devel libXi-devel libXmu-devel libXdamage-devel git \ |
| expat-devel llvm-devel |
| </pre> |
| <h1 id="autoconf">2. Building with autoconf (Linux/Unix/X11)</h1> |
| <p> |
| The primary method to build Mesa on Unix systems is with autoconf. |
| </p> |
| <p> |
| The general approach is the standard: |
| </p> |
| <pre> |
| ./configure |
| make |
| sudo make install |
| </pre> |
| <p> |
| But please read the <a href="autoconf.html">detailed autoconf instructions</a> |
| for more details. |
| </p> |
| <h1 id="scons">3. Building with SCons (Windows/Linux)</h1> |
| <p> |
| To build Mesa with SCons on Linux or Windows do |
| </p> |
| <pre> |
| scons |
| </pre> |
| <p> |
| The build output will be placed in |
| build/<i>platform</i>-<i>machine</i>-<i>debug</i>/..., where <i>platform</i> is for |
| example linux or windows, <i>machine</i> is x86 or x86_64, optionally followed |
| by -debug for debug builds. |
| </p> |
| <p> |
| To build Mesa with SCons for Windows on Linux using the MinGW crosscompiler toolchain do |
| </p> |
| <pre> |
| scons platform=windows toolchain=crossmingw machine=x86 mesagdi libgl-gdi |
| </pre> |
| <p> |
| This will create: |
| </p> |
| <ul> |
| <li>build/windows-x86-debug/mesa/drivers/windows/gdi/opengl32.dll — Mesa + swrast, binary compatible with Windows's opengl32.dll |
| <li>build/windows-x86-debug/gallium/targets/libgl-gdi/opengl32.dll — Mesa + Gallium + softpipe, binary compatible with Windows's opengl32.dll |
| </ul> |
| <p> |
| Put them all in the same directory to test them. |
| </p> |
| <h1 id="other">4. Building for other systems</h1> |
| <p> |
| Documentation for other environments (some may be very out of date): |
| </p> |
| <ul> |
| <li><a href="README.VMS">README.VMS</a> - VMS |
| <li><a href="README.CYGWIN">README.CYGWIN</a> - Cygwin |
| <li><a href="README.WIN32">README.WIN32</a> - Win32 |
| </ul> |
| <h1 id="libs">5. Library Information</h1> |
| <p> |
| When compilation has finished, look in the top-level <code>lib/</code> |
| (or <code>lib64/</code>) directory. |
| You'll see a set of library files similar to this: |
| </p> |
| <pre> |
| lrwxrwxrwx 1 brian users 10 Mar 26 07:53 libGL.so -> libGL.so.1* |
| lrwxrwxrwx 1 brian users 19 Mar 26 07:53 libGL.so.1 -> libGL.so.1.5.060100* |
| -rwxr-xr-x 1 brian users 3375861 Mar 26 07:53 libGL.so.1.5.060100* |
| lrwxrwxrwx 1 brian users 14 Mar 26 07:53 libOSMesa.so -> libOSMesa.so.6* |
| lrwxrwxrwx 1 brian users 23 Mar 26 07:53 libOSMesa.so.6 -> libOSMesa.so.6.1.060100* |
| -rwxr-xr-x 1 brian users 23871 Mar 26 07:53 libOSMesa.so.6.1.060100* |
| </pre> |
| <p> |
| <b>libGL</b> is the main OpenGL library (i.e. Mesa). |
| <br> |
| <b>libOSMesa</b> is the OSMesa (Off-Screen) interface library. |
| </p> |
| <p> |
| If you built the DRI hardware drivers, you'll also see the DRI drivers: |
| </p> |
| <pre> |
| -rwxr-xr-x 1 brian users 16895413 Jul 21 12:11 i915_dri.so |
| -rwxr-xr-x 1 brian users 16895413 Jul 21 12:11 i965_dri.so |
| -rwxr-xr-x 1 brian users 11849858 Jul 21 12:12 r200_dri.so |
| -rwxr-xr-x 1 brian users 11757388 Jul 21 12:12 radeon_dri.so |
| </pre> |
| <p> |
| If you built with Gallium support, look in lib/gallium/ for Gallium-based |
| versions of libGL and device drivers. |
| </p> |
| <h1 id="pkg-config">6. Building OpenGL programs with pkg-config</h1> |
| <p> |
| Running <code>make install</code> will install package configuration files |
| for the pkg-config utility. |
| </p> |
| <p> |
| When compiling your OpenGL application you can use pkg-config to determine |
| the proper compiler and linker flags. |
| </p> |
| <p> |
| For example, compiling and linking a GLUT application can be done with: |
| </p> |
| <pre> |
| gcc `pkg-config --cflags --libs glut` mydemo.c -o mydemo |
| </pre> |

| <iframe src="contents.html"></iframe> |
| <div class="content"> |
| <h1>Introduction</h1> |
| <p> |
| Mesa is an open-source implementation of the |
| <a href="http://www.opengl.org/">OpenGL</a> specification - |
| a system for rendering interactive 3D graphics. |
| </p> |
| <p> |
| A variety of device drivers allows Mesa to be used in many different |
| environments ranging from software emulation to complete hardware acceleration |
| for modern GPUs. |
| </p> |
| <p> |
| Mesa ties into several other open-source projects: the |
| <a href="http://dri.freedesktop.org/">Direct Rendering |
| Infrastructure</a> and <a href="http://x.org">X.org</a> to |
| provide OpenGL support to users of X on Linux, FreeBSD and other operating |
| systems. |
| </p> |
| <h1>Project History</h1> |
| <p> |
| The Mesa project was originally started by Brian Paul. |
| Here's a short history of the project. |
| </p> |
| <p> |
| August, 1993: I begin working on Mesa in my spare time. The project |
| has no name at that point. I was simply interested in writing a simple |
| 3D graphics library that used the then-new OpenGL API. I was partially |
| inspired by the <em>VOGL</em> library which emulated a subset of IRIS GL. |
| I had been programming with IRIS GL since 1991. |
| </p> |
| <p> |
| November 1994: I contact SGI to ask permission to distribute my OpenGL-like |
| graphics library on the internet. SGI was generally receptive to the |
| idea and after negotiations with SGI's legal department, I get permission |
| to release it. |
| </p> |
| <p> |
| February 1995: Mesa 1.0 is released on the internet. I expected that |
| a few people would be interested in it, but not thousands. |
| I was soon receiving patches, new features and thank-you notes on a |
| daily basis. That encouraged me to continue working on Mesa. The |
| name Mesa just popped into my head one day. SGI had asked me not to use |
| the terms <em>"Open"</em> or <em>"GL"</em> in the project name and I didn't |
| want to make up a new acronym. Later, I heard of the Mesa programming |
| language and the Mesa spreadsheet for NeXTStep. |
| </p> |
| <p> |
| In the early days, OpenGL wasn't available on too many systems. |
| It even took a while for SGI to support it across their product line. |
| Mesa filled a big hole during that time. |
| For a lot of people, Mesa was their first introduction to OpenGL. |
| I think SGI recognized that Mesa actually helped to promote |
| the OpenGL API, so they didn't feel threatened by the project. |
| </p> |
| <p> |
| 1995-1996: I continue working on Mesa both during my spare time and during |
| my work hours at the Space Science and Engineering Center at the University |
| of Wisconsin in Madison. My supervisor, Bill Hibbard, lets me do this because |
| Mesa is now being using for the <a href="http://www.ssec.wisc.edu/%7Ebillh/vis.html">Vis5D</a> project. |
| </p><p> |
| October 1996: Mesa 2.0 is released. It implements the OpenGL 1.1 specification. |
| </p> |
| <p> |
| March 1997: Mesa 2.2 is released. It supports the new 3dfx Voodoo graphics |
| card via the Glide library. It's the first really popular hardware OpenGL |
| implementation for Linux. |
| </p> |
| <p> |
| September 1998: Mesa 3.0 is released. It's the first publicly-available |
| implementation of the OpenGL 1.2 API. |
| </p> |
| <p> |
| March 1999: I attend my first OpenGL ARB meeting. I contribute to the |
| development of several official OpenGL extensions over the years. |
| </p> |
| <p> |
| September 1999: I'm hired by Precision Insight, Inc. Mesa is a key |
| component of 3D hardware acceleration in the new DRI project for XFree86. |
| Drivers for 3dfx, 3dLabs, Intel, Matrox and ATI hardware soon follow. |
| </p> |
| <p> |
| October 2001: Mesa 4.0 is released. |
| It implements the OpenGL 1.3 specification. |
| </p> |
| <p> |
| November 2001: I cofounded Tungsten Graphics, Inc. with Keith Whitwell, |
| Jens Owen, David Dawes and Frank LaMonica. |
| Tungsten Graphics was acquired by VMware in December 2008. |
| </p> |
| <p> |
| November 2002: Mesa 5.0 is released. |
| It implements the OpenGL 1.4 specification. |
| </p> |
| <p> |
| January 2003: Mesa 6.0 is released. It implements the OpenGL 1.5 |
| specification as well as the GL_ARB_vertex_program and |
| GL_ARB_fragment_program extensions. |
| </p> |
| <p> |
| June 2007: Mesa 7.0 is released, implementing the OpenGL 2.1 specification |
| and OpenGL Shading Language. |
| </p> |
| <p> |
| 2008: Keith Whitwell and other Tungsten Graphics employees develop |
| <a href="http://en.wikipedia.org/wiki/Gallium3D">Gallium</a> |
| - a new GPU abstraction layer. The latest Mesa drivers are based on |
| Gallium and other APIs such as OpenVG are implemented on top of Gallium. |
| </p> |
| <p> |
| February 2012: Mesa 8.0 is released, implementing the OpenGL 3.0 specification |
| and version 1.30 of the OpenGL Shading Language. |
| </p> |
| <p> |
| Ongoing: Mesa is the OpenGL implementation for several types of hardware |
| made by Intel, AMD and NVIDIA, plus the VMware virtual GPU. |
| There's also several software-based renderers: swrast (the legacy |
| Mesa rasterizer), softpipe (a gallium reference driver) and llvmpipe |
| (LLVM/JIT-based high-speed rasterizer). |
| Work continues on the drivers and core Mesa to implement newer versions |
| of the OpenGL specification. |
| </p> |
| <h1>Major Versions</h1> |
| <p> |
| This is a summary of the major versions of Mesa. |
| Mesa's major version number has been incremented whenever a new version |
| of the OpenGL specification is implemented. |
| </p> |
| <h2>Version 9.x features</h2> |
| <p> |
| Version 9.x of Mesa implements the OpenGL 3.1 API. |
| While the driver for Intel Sandy Bridge and Ivy Bridge is the only |
| driver to support OpenGL 3.1, many developers across the open-source |
| community contributed features required for OpenGL 3.1. The primary |
| features added since the Mesa 8.0 release are |
| GL_ARB_texture_buffer_object and GL_ARB_uniform_buffer_object. |
| </p> |
| <h2>Version 8.x features</h2> |
| <p> |
| Version 8.x of Mesa implements the OpenGL 3.0 API. |
| The developers at Intel deserve a lot of credit for implementing most |
| of the OpenGL 3.0 features in core Mesa, the GLSL compiler as well as |
| the i965 driver. |
| </p> |
| <h2>Version 7.x features</h2> |
| <p> |
| Version 7.x of Mesa implements the OpenGL 2.1 API. The main feature |
| of OpenGL 2.x is the OpenGL Shading Language. |
| </p> |
| <h2>Version 6.x features</h2> |
| <p> |
| Version 6.x of Mesa implements the OpenGL 1.5 API with the following |
| extensions incorporated as standard features: |
| </p> |
| <ul> |
| <li>GL_ARB_occlusion_query |
| <li>GL_ARB_vertex_buffer_object |
| <li>GL_EXT_shadow_funcs |
| </ul> |
| <p> |
| Also note that several OpenGL tokens were renamed in OpenGL 1.5 |
| for the sake of consistency. |
| The old tokens are still available. |

| Introduction |
| ------------ |
| This document describes the implementation of the XFree86 4.0 libGL.so |
| library defined by the Linux/OpenGL Base specification found at |
| http://reality.sgi.com/opengl/linux/linuxbase.html. |
| The documentation is divided into two sections: |
| User's Guide |
| Driver Developer's Guide |
| Author: Brian Paul (brian@precisioninsight.com) |
| Date: February 2000 |
| User's Guide |
| ------------ |
| Using libGL.so |
| The libGL.so library defines the gl- and glX-prefixed functions needed to |
| run OpenGL programs. OpenGL client applications should link with the |
| -lGL option to use it. |
| libGL.so serves two primary functions: GLX protocol generation for indirect |
| rendering and loading/management of hardware drivers for direct rendering. |
| When libGL.so initializes itself it uses the DRI to determine the |
| appropriate hardware driver for each screen on the local X display. |
| The hardware drivers are expected to be in the /usr/X11R6/lib/modules/dri/ |
| directory. Drivers are named with the convention <name>_dri.so where |
| <name> is a driver such as "radeon", "i965", "nouveau", etc. |
| The LIBGL_DRIVERS_DIR environment variable may be used to specify a |
| different DRI modules directory, overriding /usr/X11R6/lib/modules/dri/. |
| This environment variable is ignored in setuid programs for security |
| reasons. |
| When libGL.so is unable to locate appropriate hardware drivers it will |
| fall back to using indirect GLX rendering. |
| To aid in solving problems, libGL.so will print diagnostic messages to |
| stderr if the LIBGL_DEBUG environment variable is defined. |
| libGL.so is thread safe. The overhead of thread safety for common, |
| single-thread clients is negligible. However, the overhead of thread |
| safety for multi-threaded clients is significant. Each GL API call |
| requires two calls to pthread_get_specific() which can noticably |
| impact performance. Warning: libGL.so is thread safe but individual |
| DRI drivers may not be. Please consult the documentation for a driver |
| to learn if it is thread safe. |
| Indirect Rendering |
| You can force indirect rendering mode by setting the LIBGL_ALWAYS_INDIRECT |
| environment variable. Hardware acceleration will not be used. |
| libGL.so Extensibility |
| libGL.so is designed to be extended without upgrading. That is, |
| drivers may install new OpenGL extension functions into libGL.so |
| without requiring libGL.so to be replaced. Clients of libGL.so should |
| use the glXGetProcAddressEXT() function to obtain the address of |
| functions by name. For more details of GLX_ARB_get_proc_address see |
| http://oss.sgi.com/projects/ogl-sample/registry/ARB/get_proc_address.spec |
| libGL.so is also designed with flexibility such that it may be used |
| with many generations of hardware drivers to come. |
| Driver Developer's Guide |
| ------------------------ |
| This section describes the requirements to make an XFree86 4.0 |
| libGL.so-compatible hardware driver. It is not intended for end |
| users of libGL.so. |
| XFree86 source files |
| libGL.so is built inside XFree86 with sources found in xc/lib/GL/. |
| Specifically, libGL.so is built from: |
| xc/lib/GL/glx/*.c |
| xc/lib/dri/XF86dri.c |
| xc/lib/dri/dri_glx.c |
| xc/lib/GL/mesa/src/glapi.c |
| xc/lib/GL/mesa/src/glapitemp.h |
| xc/lib/GL/mesa/src/glapitable.h |
| xc/lib/GL/mesa/src/glapioffsets.h |
| xc/lib/GL/mesa/src/glapinoop.c |
| xc/lib/GL/mesa/src/glheader.h |
| xc/lib/GL/mesa/src/glthread.c |
| xc/lib/GL/mesa/src/glthread.h |
| xc/lib/GL/mesa/src/X86/glapi_x86.S |
| xc/lib/GL/mesa/src/X86/assyntax.h |
| Understand that the mesa/src/gl*.[ch] files are not tied to Mesa. They |
| have no dependencies on the rest of Mesa and are designed to be reusable |
| in a number of projects. |
| The glapi_x86.X and assyntax.h files implement x86-optimized dispatch |
| of GL functions. They are not required; C-based dispatch can be used |
| instead, with a slight performance penalty. |
| Driver loading and binding |
| When libGL.so initializes itself (via the __glXInitialize function) a |
| call is made to driCreateDisplay(). This function uses DRI facilities |
| to determine the driver file appropriate for each screen on the local |
| display. Each screen's driver is then opened with dlopen() and asked |
| for its __driCreateScreen() function. The pointers to the __driCreateScreen() |
| functions are kept in an array, indexed by screen number, in the |
| __DRIdisplayRec struct. |
| When a driver's __driCreateScreen() function is called, it must initialize |
| a __DRIscreenRec struct. This struct acts as the root of a tree of |
| function pointers which are called to create and destroy contexts and |
| drawables and perform all the operations needed by the GLX interface. |
| See the xc/lib/GL/glx/glxclient.h file for details. |
| Dynamic Extension Function Registration |
| In order to provide forward compatibility with future drivers, libGL.so |
| allows drivers to register new OpenGL extension functions which weren't |
| known when libGL.so was built. |
| The register_extensions() function in xc/lib/GL/dri/dri_glx.c is called |
| as soon as libGL.so is loaded. This is done with gcc's constructor |
| attribute. This mechanism will likely have to be changed for other compilers. |
| register_extensions() loops over all local displays and screens, determines |
| the DRI driver for each, and calls the driver's __driRegisterExtensions() |
| function, if present. |
| The __driRegisterExtensions() function can add new entrypoints to libGL |
| by calling: |
| GLboolean _glapi_add_entrypoint(const char *funcName, GLuint offset) |
| The parameters are the name of the function (such as "glFoobarEXT") and the |
| offset of the dispatch slot in the API dispatch table. The return value |
| indicates success (GL_TRUE) or failure (GL_FALSE). |
| _glapi_add_entrypoint() will synthesize entrypoint code in assembly |
| language. Assembly languages is required since parameter passing |
| can't be handled correctly using a C-based solution. |
| The address of the new entrypoint is obtained by calling the |
| glXGetProcAddressARB() function. |
| The dispatch offset number MUST be a number allocated by SGI in the same |
| manner in which new GL_* constants are allocated. Using an arbitrary |
| offset number will result in many problems. |
| Dispatch Management |
| When a GL context is made current, the driver must install its dispatch |
| table as the current dispatch table. This is done by calling |
| void _glapi_set_dispatch(struct _glapi_table *dispatch); |
| This will install the named dispatch table for the calling thread. |
| The current dispatch table for a thread can be obtained by calling |
| struct _glapi_table *_glapi_get_dispatch(void); |
| For higher performance in the common single-thread case, the global |
| variable _glapi_Dispatch will point to the current dispatch table. |
| This variable will be NULL when in multi-thread mode. |
| Context Management |
| libGL.so uses the XFree86 xthreads package to manage a thread-specific |
| current context pointer. See __glXGet/SetCurrentContext() in glext.c |
| Drivers may use the _glapi_set/get_context() functions to maintain |
| a private thread-specific context pointer. |

| <div class="content"> |
| <h1>Introduction</h1> |
| <p> |
| The Gallium llvmpipe driver is a software rasterizer that uses LLVM to |
| do runtime code generation. |
| Shaders, point/line/triangle rasterization and vertex processing are |
| implemented with LLVM IR which is translated to x86 or x86-64 machine |
| code. |
| Also, the driver is multithreaded to take advantage of multiple CPU cores |
| (up to 8 at this time). |
| It's the fastest software rasterizer for Mesa. |
| </p> |
| <h1>Requirements</h1> |
| <ul> |
| <li> |
| <p>An x86 or amd64 processor; 64-bit mode recommended.</p> |
| <p> |
| Support for SSE2 is strongly encouraged. Support for SSSE3 and SSE4.1 will |
| yield the most efficient code. The fewer features the CPU has the more |
| likely is that you run into underperforming, buggy, or incomplete code. |
| </p> |
| <p> |
| See /proc/cpuinfo to know what your CPU supports. |
| </p> |
| </li> |
| <li> |
| <p>LLVM: version 2.9 recommended; 2.6 or later required.</p> |
| <p><b>NOTE</b>: LLVM 2.8 and earlier will not work on systems that support the |
| Intel AVX extensions (e.g. Sandybridge). LLVM's code generator will |
| fail when trying to emit AVX instructions. This was fixed in LLVM 2.9. |
| </p> |
| <p> |
| For Linux, on a recent Debian based distribution do: |
| </p> |
| <pre> |
| aptitude install llvm-dev |
| </pre> |
| <p> |
| For a RPM-based distribution do: |
| </p> |
| <pre> |
| yum install llvm-devel |
| </pre> |
| <p> |
| For Windows you will need to build LLVM from source with MSVC or MINGW |
| (either natively or through cross compilers) and CMake, and set the LLVM |
| environment variable to the directory you installed it to. |
| LLVM will be statically linked, so when building on MSVC it needs to be |
| built with a matching CRT as Mesa, and you'll need to pass |
| -DLLVM_USE_CRT_RELEASE=MTd for debug and checked builds, |
| -DLLVM_USE_CRT_RELEASE=MTd for profile and release builds. |
| You can build only the x86 target by passing -DLLVM_TARGETS_TO_BUILD=X86 |
| to cmake. |
| </p> |
| </li> |
| <li> |
| <p>scons (optional)</p> |
| </li> |
| </ul> |
| <h1>Building</h1> |
| To build everything on Linux invoke scons as: |
| <pre> |
| scons build=debug libgl-xlib |
| </pre> |
| Alternatively, you can build it with GNU make, if you prefer, by invoking it as |
| <pre> |
| make linux-llvm |
| </pre> |
| but the rest of these instructions assume that scons is used. |
| For Windows the procedure is similar except the target: |
| <pre> |
| scons build=debug libgl-gdi |
| </pre> |
| <h1>Using</h1> |
| On Linux, building will create a drop-in alternative for libGL.so into |
| <pre> |
| build/foo/gallium/targets/libgl-xlib/libGL.so |
| </pre> |
| or |
| <pre> |
| lib/gallium/libGL.so |
| </pre> |
| To use it set the LD_LIBRARY_PATH environment variable accordingly. |
| For performance evaluation pass debug=no to scons, and use the corresponding |
| lib directory without the "-debug" suffix. |
| On Windows, building will create a drop-in alternative for opengl32.dll. To use |
| it put it in the same directory as the application. It can also be used by |
| replacing the native ICD driver, but it's quite an advanced usage, so if you |
| need to ask, don't even try it. |
| <h1>Profiling</h1> |
| <p> |
| To profile llvmpipe you should build as |
| </p> |
| <pre> |
| scons build=profile <same-as-before> |
| </pre> |
| <p> |
| This will ensure that frame pointers are used both in C and JIT functions, and |
| that no tail call optimizations are done by gcc. |
| </p> |
| <h2>Linux perf integration</h2> |
| <p> |
| On Linux, it is possible to have symbol resolution of JIT code with <a href="http://perf.wiki.kernel.org/">Linux perf</a>: |
| </p> |
| <pre> |
| perf record -g /my/application |
| perf report |
| </pre> |
| <p> |
| When run inside Linux perf, llvmpipe will create a /tmp/perf-XXXXX.map file with |
| symbol address table. It also dumps assembly code to /tmp/perf-XXXXX.map.asm, |
| which can be used by the bin/perf-annotate-jit script to produce disassembly of |
| the generated code annotated with the samples. |
| </p> |
| <p>You can obtain a call graph via |
| <a href="http://code.google.com/p/jrfonseca/wiki/Gprof2Dot#linux_perf">Gprof2Dot</a>.</p> |
| <h1>Unit testing</h1> |
| <p> |
| Building will also create several unit tests in |
| build/linux-???-debug/gallium/drivers/llvmpipe: |
| </p> |
| <ul> |
| <li> lp_test_blend: blending |
| <li> lp_test_conv: SIMD vector conversion |
| <li> lp_test_format: pixel unpacking/packing |
| </ul> |
| <p> |
| Some of this tests can output results and benchmarks to a tab-separated-file |
| for posterior analysis, e.g.: |
| </p> |
| <pre> |
| build/linux-x86_64-debug/gallium/drivers/llvmpipe/lp_test_blend -o blend.tsv |
| </pre> |
| <h1>Development Notes</h1> |
| <ul> |
| <li> |
| When looking to this code by the first time start in lp_state_fs.c, and |
| then skim through the lp_bld_* functions called in there, and the comments |
| at the top of the lp_bld_*.c functions. |
| </li> |
| <li> |
| The driver-independent parts of the LLVM / Gallium code are found in |
| src/gallium/auxiliary/gallivm/. The filenames and function prefixes |
| need to be renamed from "lp_bld_" to something else though. |
| </li> |
| <li> |
| We use LLVM-C bindings for now. They are not documented, but follow the C++ |
| interfaces very closely, and appear to be complete enough for code |
| generation. See |
| http://npcontemplation.blogspot.com/2008/06/secret-of-llvm-c-bindings.html |
| for a stand-alone example. See the llvm-c/Core.h file for reference. |

| <p> |
| To do this, recompile Mesa with the compiler flag -DUSE_MGL_NAMESPACE. |
| Add the flag to CFLAGS in the configuration file which you want to use. |
| For example: |
| </p> |
| <pre> |
| CFLAGS += -DUSE_MGL_NAMESPACE |

| <h1>OpenGL ES</h1> |
| <p>Mesa implements OpenGL ES 1.1 and OpenGL ES 2.0. More informations about |
| OpenGL ES can be found at <a href="http://www.khronos.org/opengles/"> |
| http://www.khronos.org/opengles/</a>.</p> |
| <p>OpenGL ES depends on a working EGL implementation. Please refer to |
| <a href="egl.html">Mesa EGL</a> for more information about EGL.</p> |
| <h2>Build the Libraries</h2> |
| <ol> |
| <li>Run <code>configure</code> with <code>--enable-gles1 --enable-gles2</code> and enable the Gallium driver for your hardware.</li> |
| <li>Build and install Mesa as usual.</li> |
| </ol> |
| Alternatively, if XCB-DRI2 is installed on the system, one can use |
| <code>egl_dri2</code> EGL driver with OpenGL|ES-enabled DRI drivers |
| <ol> |
| <li>Run <code>configure</code> with <code>--enable-gles1 --enable-gles2</code>.</li> |
| <li>Build and install Mesa as usual.</li> |
| </ol> |
| <p>Both methods will install libGLESv1_CM, libGLESv2, libEGL, and one or more |
| EGL drivers for your hardware.</p> |
| <h2>Run the Demos</h2> |
| <p>There are some demos in <code>mesa/demos</code> repository.</p> |
| <h2>Developers</h2> |
| <h3>Dispatch Table</h3> |
| <p>OpenGL ES has an additional indirection when dispatching fucntions</p> |
| <pre> |
| Mesa: glFoo() --> _mesa_Foo() |
| OpenGL ES: glFoo() --> _es_Foo() --> _mesa_Foo() |
| </pre> |
| <p>The indirection serves several purposes</p> |
| <ul> |
| <li>When a function is in Mesa and the type matches, it checks the arguments and calls the Mesa function.</li> |
| <li>When a function is in Mesa but the type mismatches, it checks and converts the arguments before calling the Mesa function.</li> |
| <li>When a function is not available in Mesa, or accepts arguments that are not available in OpenGL, it provides its own implementation.</li> |
| </ul> |
| <p>Other than the last case, OpenGL ES uses <code>APIspec.xml</code> to generate functions to check and/or converts the arguments.</p> |

| <h1>Off-screen Rendering</h1> |
| <p> |
| Mesa's off-screen interface is used for rendering into user-allocated memory |
| without any sort of window system or operating system dependencies. |
| That is, the GL_FRONT colorbuffer is actually a buffer in main memory, |
| rather than a window on your display. |
| </p> |
| <p> |
| The OSMesa API provides three basic functions for making off-screen |
| renderings: OSMesaCreateContext(), OSMesaMakeCurrent(), and |
| OSMesaDestroyContext(). See the Mesa/include/GL/osmesa.h header for |
| more information about the API functions. |
| </p> |
| <p> |
| The OSMesa interface may be used with any of three software renderers: |
| </p> |
| <ol> |
| <li>llvmpipe - this is the high-performance Gallium LLVM driver |
| <li>softpipe - this it the reference Gallium software driver |
| <li>swrast - this is the legacy Mesa software rasterizer |
| </ol> |
| <p> |
| There are several examples of OSMesa in the mesa/demos repository. |
| </p> |
| <h1>Building OSMesa</h1> |
| <p> |
| Configure and build Mesa with something like: |
| <pre> |
| configure --enable-osmesa --disable-driglx-direct --disable-dri --with-gallium-drivers=swrast |
| make |
| </pre> |
| <p> |
| Make sure you have LLVM installed first if you want to use the llvmpipe driver. |
| </p> |
| <p> |
| When the build is complete you should find: |
| </p> |
| <pre> |
| lib/libOSMesa.so (swrast-based OSMesa) |
| lib/gallium/libOSMsea.so (gallium-based OSMesa) |
| </pre> |
| <p> |
| Set your LD_LIBRARY_PATH to point to one directory or the other to select |
| the library you want to use. |
| </p> |
| <p> |
| When you link your application, link with -lOSMesa |

| <h1>Performance Tips</h1> |
| <p> |
| Performance tips for software rendering: |
| </p> |
| <ol> |
| <li> Turn off smooth shading when you don't need it (glShadeModel) |
| <li> Turn off depth buffering when you don't need it. |
| <li> Turn off dithering when not needed. |
| <li> Use double buffering as it's often faster than single buffering |
| <li> Compile in the X Shared Memory extension option if it's supported |
| on your system by adding -DSHM to CFLAGS and -lXext to XLIBS for |
| your system in the Make-config file. |
| <li> Recompile Mesa with more optimization if possible. |
| <li> Try to maximize the amount of drawing done between glBegin/glEnd pairs. |
| <li> Use the MESA_BACK_BUFFER variable to find best performance in double |
| buffered mode. (X users only) |
| <li> Optimized polygon rasterizers are employed when: |
| rendering into back buffer which is an XImage |
| RGB mode, not grayscale, not monochrome |
| depth buffering is GL_LESS, or disabled |
| flat or smooth shading |
| dithered or non-dithered |
| no other rasterization operations enabled (blending, stencil, etc) |
| <li> Optimized line drawing is employed when: |
| rendering into back buffer which is an XImage |
| RGB mode, not grayscale, not monochrome |
| depth buffering is GL_LESS or disabled |
| flat shading |
| dithered or non-dithered |
| no other rasterization operations enabled (blending, stencil, etc) |
| <li> Textured polygons are fastest when: |
| using a 3-component (RGB), 2-D texture |
| minification and magnification filters are GL_NEAREST |
| texture coordinate wrap modes for S and T are GL_REPEAT |
| GL_DECAL environment mode |
| glHint( GL_PERSPECTIVE_CORRECTION_HINT, GL_FASTEST ) |
| depth buffering is GL_LESS or disabled |
| <li> Lighting is fastest when: |
| Two-sided lighting is disabled |
| GL_LIGHT_MODEL_LOCAL_VIEWER is false |
| GL_COLOR_MATERIAL is disabled |
| No spot lights are used (all GL_SPOT_CUTOFFs are 180.0) |
| No local lights are used (all position W's are 0.0) |
| All material and light coefficients are >= zero |
| <li> XFree86 users: if you want to use 24-bit color try starting your |
| X server in 32-bit per pixel mode for better performance. That is, |
| start your X server with |
| startx -- -bpp 32 |
| instead of |
| startx -- -bpp 24 |
| <li> Try disabling dithering with the MESA_NO_DITHER environment variable. |
| If this env var is defined Mesa will disable dithering and the |
| command glEnable(GL_DITHER) will be ignored. |

| <h1>Gallium Post-processing</h1> |
| <p> |
| The Gallium drivers support user-defined image post-processing. |
| At the end of drawing a frame a post-processing filter can be applied to |
| the rendered image. |
| Example filters include morphological antialiasing and cell shading. |
| </p> |
| <p> |
| The filters can be toggled per-app via driconf, or per-session via the |
| corresponding environment variables. |
| </p> |
| <p> |
| Multiple filters can be used together. |
| </p> |
| <h2>PP environment variables</h2> |
| <ul> |
| <li>PP_DEBUG - If defined debug information will be printed to stderr. |
| </ul> |
| <h2>Current filters</h2> |
| <ul> |
| <li>pp_nored, pp_nogreen, pp_noblue - set to 1 to remove the corresponding color channel. |
| These are basic filters for easy testing of the PP queue. |
| <li>pp_jimenezmlaa, pp_jimenezmlaa_color - |
| <a href="http://www.iryokufx.com/mlaa/" target=_blank>Jimenez's MLAA</a> |
| is a morphological antialiasing filter. |
| The two versions use depth and color data, respectively. |
| Which works better depends on the app - depth will not blur text, but it will |
| miss transparent textures for example. |
| Set to a number from 2 to 32, roughly corresponding to quality. |
| Numbers higher than 8 see minimizing gains. |
| <li>pp_celshade - set to 1 to enable cell shading (a more complex color filter). |

| Mesa 3.1 release notes |
| PLEASE READ!!!! |
| New copyright |
| ------------- |
| Mesa 3.1 will be distributed under an XFree86-style copyright instead |
| of the GNU LGPL. |
| New directories |
| --------------- |
| All documentation files are now in the docs/ directory. |
| All shell scripts are now in the bin/ directory. |
| New library names |
| ----------------- |
| Formerly, the main Mesa library was named libMesaGL.so (or libMesaGL.a) |
| and the GLU library was named libMesaGLU.so (or libMesaGLU.a). |
| Now, the main library is named libGL.so (or libGL.a) and the GLU library |
| is named libGLU.so (or libGLU.a). |
| The change allows Mesa to be more easily substituted for OpenGL. |
| Specifically, the linker/loader on some Unix-like systems won't |
| allow libMesaGL.so to be used instead of libGL.so if the application |
| was linked with the former. |
| Warning: if you have another OpenGL implementation installed on your |
| system (i.e. you have another OpenGL libGL.so) you'll have to be |
| carefull about which library (OpenGL or Mesa) you link against. Be |
| aware of -L linker flags and the value of the LD_LIBRARY_PATH environment |
| variable. |
| New library versioning |
| ---------------------- |
| Previously, the Mesa GL library was named libMesaGL.so.3.0 |
| To better support Linux/OpenGL standards, the Mesa GL library is now |
| named libGL.so.1.2.030100 This indicates version 1.2 of the OpenGL spec |
| and Mesa implementation 3.1.0 |
| In the long term this will allow better interoperability with other |
| OpenGL implementations, especially on Linux. In the short term, |
| OpenGL apps may have to be relinked to use the new library naming. |
| New makefiles |
| ------------- |
| The old Makefiles found in the various directories have been renamed |
| to Makefile.X11 in order to prevent filename collisions with autoconfig- |
| generated Makefiles. |
| The top-level Makefile simply includes Makefile.X11 |
| If your top-level Makefile get's overwritten/destroyed you can restore |
| it by copying Makefile.X11 to Makefile |
| New extensions |
| -------------- |
| GL_EXT_stencil_wrap |
| Implements two new stencil operations: GL_INCR_WRAP_EXT and |
| GL_DECR_WRAP_EXT which allow stencil increment and decrement |
| without clamping. |
| GL_INGR_blend_func_separate |
| Allows specification of blend factors for RGB and Alpha independently. |
| (INGR = Intergraph) |
| GL_ARB_multitexture |
| Multiple simultaneous textures. (ARB = Architecture Review Board) |
| GL_NV_texgen_reflection |
| nVidia texgen extension for better reflection mapping. |
| GL_PGI_misc_hints |
| Assorted transformation hints. |
| GL_EXT_compiled_vertex_array |
| Compiled vertex arrays. |
| GL_EXT_clip_volume_hint |
| Allows one to disable clip volume (frustum) testing. |
| Extensions removed |
| ------------------ |
| GL_EXT_multitexture - obsolete in favor of GL_ARB_multitexture |
| Config file |
| ----------- |
| By default, /etc/mesa.conf will be read when Mesa starts. This |
| file controls default hints, enable/disable of extensions, and |
| more. See the CONFIG file for documentation. |
| Optimizations |
| ------------- |
| Keith Whitwell has contributed significant optimizations to Mesa's |
| vertex transformation code. Basically, the whole transformation |
| stage of Mesa has been rewritten. |
| It's impossible to give a speedup factor. You'll just have to |
| try your app and see how it performs. |
| Device Driver changes |
| --------------------- |
| A bunch of new device driver functions have been added. See src/dd.h |
| Keith Harrison contributed many of them. I've been planning on adding |
| a bunch of functions like these to make writing hardware drivers easier. |
| More such function will probably be added in the near future. |
| Miscellaneous |
| ------------- |
| util/glstate.c has some handy functions for debugging. Basically, it |
| offers a simple function for printing GL state variables. It's not |
| finished yet. There's a LOT more GLenum records to be added (see the |
| code). Anyone want to help? |

| PLEASE READ!!!! |
| The Mesa 3.2.1 release mainly just fixes bugs since the 3.2 release. |
| See the VERSIONS file for the exact list. |
| GLU Polygon Tessellator |
| ----------------------- |
| The GLU tessellator has been reverted back to the version included |
| with Mesa 3.0 since it's more stable. The Mesa 3.1/3.2 tessellator |
| implemented the GLU 1.3 specification but suffered from a number of |
| bugs. |
| Mesa implements GLU 1.1. |
| Ideally, people should use the GLU 1.3 library included in SGI's |
| OpenGL Sample Implementation (SI) available from |
| http://oss.sgi.com/projects/ogl-sample/ |
| People are working to make easy-to-install Linux RPMs of the |
| GLU library. |

| Mesa 3.3 release notes |
| July 21, 2000 |
| PLEASE READ!!!! |
| Introduction |
| ------------ |
| Mesa uses an even/odd version number scheme like the Linux kernel. |
| Odd numbered versions (such as 3.3) designate new developmental releases. |
| Even numbered versions (such as 3.2.1) designate stable releases. |
| Mesa 3.3 has a undergone many internal changes since version 3.2 |
| and features a lot of new extensions. 3.3 is expected to be pretty |
| stable, but perhaps not as stable as 3.2 which has been used by |
| thousands of users over the past months. |
| Everyone is encouraged to try Mesa 3.3. Bugs should be reported to |
| the Mesa bug database on www.sourceforge.net. |
| Header file / GLenum changes |
| ---------------------------- |
| The gl.h and glu.h headers now use #defines to define all GL_* tokens |
| instead of C-language enums. This change improves Mesa/OpenGL |
| interoperability. |
| New API dispatch code |
| --------------------- |
| The core Mesa gl* functions are now implemented with a new dispatch |
| (jump table) which will allow simultaneous direct/indirect rendering. |
| The code is found in the glapi*.[ch] files. |
| Of interest: the actual "glFooBar" functions are generated with |
| templatized code defined in glapitemp.h and included by glapi.c |
| The glapitemp.h template should be reusable for all sorts of OpenGL |
| projects. |
| The new dispatch code has also optimized with x86 assembly code. |
| This optimization eliminates copying the function arguments during |
| dispatch. |
| New thread support |
| ------------------ |
| Thread support in Mesa has been rewritten. The glthread.[ch] files |
| replace mthreads.[ch]. Thread safety is always enabled (on platforms |
| which support threads, that is). There is virtually no performance |
| penalty for typical single-thread applications. See the glapi.c |
| file for details. |
| The Xlib driver (XMesa) is now thread-safe as well. Be sure to |
| call XInitThreads() in your app first. See the xdemos/glthreads.c |
| demo for an example. |
| Make configuration changes |
| -------------------------- |
| If you use the old-style (non GNU automake) method to build Mesa note |
| that several of the configuration names have changed: |
| Old name New name |
| ------------- ---------------- |
| linux-elf linux |
| linux linux-static |
| linux-386-elf linux-386 |
| linux-386 linux-386-static |
| etc. |
| New extensions |
| -------------- |
| GL_ARB_transpose_matrix |
| Adds glLoadTransposeMatrixARB() and glMultTransposeMatrixARB() |
| functions. |
| GL_ARB_texture_cube_map |
| For cube-based reflection mapping. |
| GL_EXT_texture_add_env |
| Adds GL_ADD texture environment mode. |
| See http://www.berkelium.com/OpenGL/EXT/texture_env_add.txt |
| GL_EXT_texture_lod_bias |
| Allows mipmapped texture blurring and sharpening. |
| GLX_EXT_visual_rating extension |
| This extension has no effect in stand-alone Mesa (used for DRI). |
| GL_HP_occlusion_test |
| Used for bounding box occlusion testing (see demos/occlude.c). |
| GL_SGIX_pixel_texture / GL_SGIS_pixel_texture |
| Lets glDraw/CopyPixels draw a texture coordinate image. |
| GL_SGI_color_matrix |
| Adds a color matrix and another set of scale and bias parameters |
| to the glDraw/CopyPixels paths. |
| GL_SGI_color_table |
| Adds additional color tables to the glDraw/Read/CopyPixels paths. |
| GL_EXT_histogram |
| Compute histograms for glDraw/Read/CopyPixels. |
| GL_EXT_blend_func_separate |
| This is the same as GL_INGR_blend_func_separate. |
| GL_ARB_texture_cube_mapping |
| 6-face cube mapping, nicer than sphere mapping |
| GL_EXT_texture_env_combine |
| For advanced texture environment effects. |
| Documentation for all these functions can be found at |
| http://oss.sgi.com/projects/ogl-sample/registry/ |
| GLX_SGI_make_current_read functionality |
| --------------------------------------- |
| The functionality of this extension is needed for GLX 1.3 (and required |
| for the Linux/OpenGL standards base). |
| Implementing this function required a **DEVICE DRIVER CHANGE**. |
| The old SetBuffer() function has been replaced by SetReadBuffer() and |
| SetDrawBuffer(). All device drivers will have to be updated because |
| of this change. |
| The new function, glXMakeContextCurrent(), in GLX 1.3 now works in Mesa. |
| The xdemos/wincopy.c program demonstrates it. |
| Image-related code changes |
| -------------------------- |
| The imaging path code used by glDrawPixels, glTexImage[123]D, |
| glTexSubImage[123], etc has been rewritten. It's now faster, |
| uses less memory and has several bug fixes. This work was |
| actually started in Mesa 3.1 with the glTexImage paths but has now |
| been carried over to glDrawPixels as well. |
| Device driver interface changes |
| ------------------------------- |
| Added new functions for hardware stencil buffer support: |
| WriteStencilSpan |
| ReadStencilSpan |
| WriteStencilPixels |
| ReadStencilPixels |
| Removed old depth buffer functions: |
| AllocDepthBuffer |
| DepthTestSpan |
| DepthTestPixels |
| ReadDepthSpanFloat |
| ReadDepthSpanInt |
| Added new depth buffer functions: |
| WriteDepthSpan |
| ReadDepthSpan |
| WriteDepthPixels |
| ReadDepthPixels |
| These functions always read/write 32-bit GLuints. This will allow |
| drivers to have anywhere from 0 to 32-bit Z buffers without |
| recompiling for 16 vs 32 bits as was previously needed. |
| New texture image functions |
| The entire interface for texture image specification has been updated. |
| With the new functions, it's optional for Mesa to keep an internal copy |
| of all textures. Texture download should be a lot faster when the extra |
| copy isn't made. |
| Misc changes |
| TexEnv now takes a target argument |
| Removed UseGlobalTexturePalette (use Enable function instead) |
| Also added |
| ReadPixels |
| CopyPixels |
| The SetBufffer function has been replaced by SetDrawBuffer and |
| SetReadBuffer functions. This lets core Mesa independently |
| specify which buffer is to be used for reading and which for |
| drawing. |
| The Clear function's mask parameter has changed. Instead of |
| mask being the flags specified by the user to glClear, the |
| mask is now a bitmask of the DD_*_BIT flags in dd.h. Now |
| multiple color buffers can be specified for clearing (ala |
| glDrawBuffers). The driver's Clear function must also |
| check the glColorMask glIndexMask, and glStencilMask settings |
| and do the right thing. See the X/Mesa, OS/Mesa, or FX/Mesa |
| drivers for examples. |
| The depth buffer changes shouldn't be hard to make for existing |
| drivers. In fact, it should simply the code. Be careful with |
| the depthBits value passed to gl_create_context(). 1 is a bad |
| value! It should normally be 0, 16, 24, or 32. |
| gl_create_framebuffer() takes new arguments which explicitly tell |
| core Mesa which ancillary buffers (depth, stencil, accum, alpha) |
| should be implemented in software. Mesa hardware drivers should |
| carefully set these flags depending on which buffers are in the |
| graphics card. |
| Internal constants |
| ------------------ |
| Point and line size range and granularity limits are now stored |
| in the gl_constants struct, which is the Const member of GLcontext. |
| The limits are initialized from values in config.h but may be |
| overridden by device drivers to reflect the limits of that driver's |
| hardware. |
| Also added constants for NumAuxBuffers and SubPixelBits. |
| OpenGL Conformance |
| ------------------ |
| Mesa now passes all the OpenGL 1.1 conformance tests, except for |
| antialiased lines. AA lines fail on some, but not all, the tests. |
| In order to fix the remaining failures, a new AA line algorithm will |
| be needed (which computes coverage values for end-point fragments). |
| This will be done for Mesa 3.5/3.6. |
| OpenGL 1.2 GL_ARB_imaging subset |
| -------------------------------- |
| Mesa 3.3 implements all the features of GL_ARB_imaging except for |
| image convolution. This will (hopefully) be done for Mesa 3.5/3.6. |

| Mesa 3.5 release notes |
| June 21, 2001 |
| PLEASE READ!!!! |
| Introduction |
| ------------ |
| Mesa uses an even/odd version number scheme like the Linux kernel. |
| Odd numbered versions (such as 3.5) designate new developmental releases. |
| Even numbered versions (such as 3.4) designate stable releases. |
| The biggest change in Mesa 3.5 is a complete overhaul of the source |
| code in order to make it more modular. This was driven by the DRI |
| hardware drivers. It simplifies the DRI drivers and opens the door |
| to hardware transform/clip/lighting (TCL). Keith Whitwell can take |
| the credit for that. |
| Driver Support |
| -------------- |
| The device driver interface in Mesa 3.5 has changed a lot since Mesa 3.4 |
| Not all of the older Mesa drivers have been updated. Here's the status: |
| Driver Status |
| ---------------------- ----------- |
| XMesa (Xlib) updated |
| OSMesa (off-screen) updated |
| FX (3dfx Voodoo1/2) updated |
| SVGA updated |
| GGI not updated |
| Windows/Win32 not updated |
| DOS/DJGPP not updated |
| BeOS not updated |
| Allegro not updated |
| D3D not updated |
| DOS not updated |
| We're looking for volunteers to update the remaining drivers. Please |
| post to the Mesa3d-dev mailing list if you can help. |
| GLU 1.3 |
| ------- |
| Mesa 3.5 includes the SGI Sample Implementation (SI) GLU library. |
| This version of GLU supports the GLU 1.3 specification. The old |
| Mesa GLU library implemented the 1.1 specification. The SI GLU |
| library should work much better. |
| You'll need a C++ compiler to compile the SI GLU library. This may |
| be a problem on some systems. |
| New Extensions |
| -------------- |
| GL_EXT_convolution |
| Adds image convolution to glRead/Copy/DrawPixels/TexImage. |
| GL_ARB_imaging |
| This is the optional imaging subset of OpenGL 1.2. |
| It's the GL_EXT_convolution, GL_HP_convolution_border_modes, |
| GL_EXT_histogram, GL_EXT_color_table, GL_EXT_color_subtable |
| GL_EXT_blend_color, GL_EXT_blend_minmax, GL_EXT_blend_subtract |
| and GL_SGI_color_matrix extensions all rolled together. |
| This is supported in all software renderers but not in all |
| hardware drivers (3dfx for example). |
| GL_ARB_texture_compression |
| This is supported in Mesa but only used by the 3dfx DRI drivers |
| for Voodoo4 and later. |
| GL_ARB_texture_env_add |
| This is identical to GL_EXT_texture_env_add. |
| GL_NV_blend_square |
| Adds extra blend source and dest factors which allow squaring |
| of color values. |
| GL_EXT_fog_coord |
| Allows specification of a per-vertex fog coordinate instead of |
| having fog always computed from the eye distance. |
| GL_EXT_secondary_color |
| Allows specifying the secondary (specular) color for each vertex |
| instead of getting it only from lighting in GL_SEPARATE_SPECULAR_COLOR |
| mode. |
| GL_ARB_texture_env_combine |
| Basically the same as GL_EXT_texture_env_combine |
| GL_ARB_texture_env_add extension |
| Texture addition mode. |
| GL_ARB_texture_env_dot3 extension |
| Dot product texture environment. |
| GL_ARB_texture_border_clamp |
| Adds GL_CLAMP_TO_BORDER_ARB texture wrap mode |
| GL_SGIX_depth_texture, GL_SGIX_shadow and GL_SGIX_shadow_ambient |
| Implements a shadow casting algorithm based on depth map textures |
| GL_SGIS_generate_mipmap |
| Automatically generate lower mipmap images whenever the base mipmap |
| image is changed with glTexImage, glCopyTexImage, etc. |
| libOSMesa.so |
| ------------ |
| libOSMesa.so is a new library which contains the OSMesa interface for |
| off-screen rendering. Apps which need the OSMesa interface should link |
| with both -lOSMesa and -lGL. This change was made so that stand-alone |
| Mesa works the same way as XFree86/DRI's libGL. |
| Device Driver Changes / Core Mesa Changes |
| ----------------------------------------- |
| The ctx->Driver.LogicOp() function has been removed. It used to |
| be called during state update in order to determine if the driver |
| could do glLogicOp() operations, and if not, set the SWLogicOpEnabled |
| flag. Drivers should instead examine the LogicOp state themselves |
| and choose specialized point, line, and triangle functions appropriately, |
| or fall back to software rendering. The Xlib driver was the only driver |
| to use this function. And since the Xlib driver no longer draws |
| points, lines or triangles using Xlib, the LogicOp function isn't needed. |
| The ctx->Driver.Dither() function has been removed. Drivers should |
| detect dither enable/disable via ctx->Driver.Enable() instead. |
| The ctx->Driver.IndexMask() and ctx->Driver.ColorMask() functions |
| are now just called from glIndexMask and glColorMask like the other |
| GL state-changing functions. They are no longer called from inside |
| gl_update_state(). Also, they now return void. The change was made |
| mostly for sake of uniformity. |
| The NEW_DRVSTATE[0123] flags have been removed. They weren't being used |
| and are obsolete w.r.t. the way state updates are done in DRI drivers. |
| Removed obsolete gl_create_visual() and gl_destroy_visual(). |
| Renamed functions (new namespace): |
| old new |
| gl_create_framebuffer _mesa_create_framebuffer |
| gl_destroy_framebuffer _mesa_destroy_framebuffer |
| gl_create_context _mesa_create_context |
| gl_destroy_context _mesa_destroy_context |
| gl_context_initialize _mesa_context_initialize |
| gl_copy_context _mesa_copy_context |
| gl_make_current _mesa_make_current |
| gl_make_current2 _mesa_make_current2 |
| gl_get_current_context _mesa_get_current_context |
| gl_flush_vb _mesa_flush_vb |
| gl_warning _mesa_warning |
| gl_compile_error _mesa_compile_error |
| All the drivers have been updated, but not all of them have been |
| tested since I can't test some platforms (DOS, Windows, Allegro, etc). |
| X/Mesa Driver |
| ------------- |
| The source files for the X/Mesa driver in src/X have been renamed. |
| The xmesa[1234].c files are gone. The new files are xm_api.c, |
| xm_dd.c, xm_line.c, xm_span.c and xm_tri.c. |
| Multitexture |
| ------------ |
| Eight texture units are now supported by default. |
| OpenGL SI related changes |
| ------------------------- |
| In an effort to make Mesa's internal interfaces more like the OpenGL |
| SI interfaces, a number of changes have been made: |
| 1. Importing the SI's glcore.h file which defines a number of |
| interface structures like __GLimports and __GLexports. |
| 2. Renamed "struct gl_context" to "struct __GLcontextRec". |
| 3. Added __glCoreCreateContext() and __glCoreNopDispatch() functions. |
| 4. The GLcontext member Visual is no longer a pointer. |
| 5. New file: imports.c to setup default import functions for Mesa. |
| 16-bit color channels |
| --------------------- |
| There's experimental support for 16-bit color channels (64-bit pixels) |
| in Mesa 3.5. Only the OSMesa interface can be used for 16-bit rendering. |
| Type "make linux-osmesa16" in the top-level directory to build the |
| special libOSMesa16.so library. |
| This hasn't been tested very thoroughly yet so please file bug reports |
| if you have trouble. |
| In the future I hope to implement support for 32-bit, floating point |
| color channels. |

| Mesa 4.0 release notes |
| October 18, 2001 |
| PLEASE READ!!!! |
| Introduction |
| ------------ |
| Mesa uses an even/odd version number scheme like the Linux kernel. |
| Odd numbered versions (such as 3.3) designate new developmental releases. |
| Even numbered versions (such as 3.4) designate stable releases. |
| Mesa version 4.0 signifies two things: |
| 1. A stabilization of the 3.5 development release |
| 2. Implementation of the OpenGL 1.3 specification |
| Note that the Mesa major version number is incremented with the OpenGL |
| minor version number: |
| Mesa 1.x == OpenGL 1.0 |
| Mesa 2.x == OpenGL 1.1 |
| Mesa 3.x == OpenGL 1.2 |
| Mesa 4.x == OpenGL 1.3 |
| New Features |
| ------------ |
| Mesa 3.5 already had all the new features of OpenGL 1.3, implemented as |
| extensions. These extensions were simply promoted to standard features: |
| GL_ARB_multisample |
| GL_ARB_multitexture |
| GL_ARB_texture_border_clamp |
| GL_ARB_texture_compression |
| GL_ARB_texture_cube_map |
| GL_ARB_texture_env_add |
| GL_ARB_texture_env_combine |
| GL_ARB_texture_env_dot3 |
| GL_ARB_transpose_matrix |
| In Mesa 4.0 the functions defined by these extensions are now available |
| without the "ARB" suffix. For example, glLoadTransposeMatrixf() is now |
| a standard API function. The new functions in OpenGL 1.3 and Mesa 4.0 are: |
| glActiveTexture |
| glClientActiveTexture |
| glCompressedTexImage1D |
| glCompressedTexImage2D |
| glCompressedTexImage3D |
| glCompressedTexSubImage1D |
| glCompressedTexSubImage2D |
| glCompressedTexSubImage3D |
| glGetCompressedTexImage |
| glLoadTransposeMatrixd |
| glLoadTransposeMatrixf |
| glMultiTexCoord1d |
| glMultiTexCoord1dv |
| glMultiTexCoord1f |
| glMultiTexCoord1fv |
| glMultiTexCoord1i |
| glMultiTexCoord1iv |
| glMultiTexCoord1s |
| glMultiTexCoord1sv |
| glMultiTexCoord2d |
| glMultiTexCoord2dv |
| glMultiTexCoord2f |
| glMultiTexCoord2fv |
| glMultiTexCoord2i |
| glMultiTexCoord2iv |
| glMultiTexCoord2s |
| glMultiTexCoord2sv |
| glMultiTexCoord3d |
| glMultiTexCoord3dv |
| glMultiTexCoord3f |
| glMultiTexCoord3fv |
| glMultiTexCoord3i |
| glMultiTexCoord3iv |
| glMultiTexCoord3s |
| glMultiTexCoord3sv |
| glMultiTexCoord4d |
| glMultiTexCoord4dv |
| glMultiTexCoord4f |
| glMultiTexCoord4fv |
| glMultiTexCoord4i |
| glMultiTexCoord4iv |
| glMultiTexCoord4s |
| glMultiTexCoord4sv |
| glMultTransposeMatrixd |
| glMultTransposeMatrixf |
| glSampleCoverage |
| glSamplePass |
| GLX 1.4 is the companion to OpenGL 1.3. The only new features in GLX 1.4 |
| are support for multisampling and the GLX_ARB_get_proc_address extension. |
| glXGetProcAddress() is the only new function in GLX 1.4. |
| Multisample and Texture Compression |
| ----------------------------------- |
| The OpenGL 1.3 specification allows the multisample and texture compression |
| features to essentially be no-ops. For example, if you query for multisample |
| support you'll find none, but the API functions work. |
| Similarly, texture compression is not implemented by any of the software |
| drivers but you can specify a generic compressed texture format (like |
| GL_COMPRESSED_RGBA) to glTexImage2D and it'll be accepted. |
| Device Drivers |
| -------------- |
| Mesa advertises itself as either OpenGL 1.2 or OpenGL 1.3 depending on the |
| device driver. If the driver enables all the ARB extensions which are part |
| of OpenGL 1.3 then glGetString(GL_VERSION) will return "1.3". Otherwise, |
| it'll return "1.2". |
| A number of Mesa's software drivers haven't been actively maintained for |
| some time. We rely on volunteers to maintain many of the drivers. |
| Here's the current status of all included drivers: |
| Driver Status |

| Mesa 4.1 release notes |
| October 29, 2002 |
| PLEASE READ!!!! |
| Introduction |
| ------------ |
| Mesa uses an even/odd version number scheme like the Linux kernel. |
| Even numbered versions (such as 4.0) designate stable releases. |
| Odd numbered versions (such as 4.1) designate new developmental releases. |
| New Features in Mesa 4.1 |
| ------------------------ |
| New extensions. Docs at http://oss.sgi.com/projects/ogl-sample/registry/ |
| GL_NV_vertex_program |
| NVIDIA's vertex programming extension |
| GL_NV_vertex_program1_1 |
| A few features built on top of GL_NV_vertex_program |
| GL_ARB_window_pos |
| This is the ARB-approved version of GL_MESA_window_pos |
| GL_ARB_depth_texture |
| This is the ARB-approved version of GL_SGIX_depth_texture. |
| It allows depth (Z buffer) data to be stored in textures. |
| This is used by GL_ARB_shadow |
| GL_ARB_shadow |
| Shadow mapping with depth textures. |
| This is the ARB-approved version of GL_SGIX_shadow. |
| GL_ARB_shadow_ambient |
| Allows one to specify the luminance of shadowed pixels. |
| This is the ARB-approved version of GL_SGIX_shadow_ambient. |
| GL_EXT_shadow_funcs |
| Extends the set of GL_ARB_shadow texture comparision functions to |
| include all eight of standard OpenGL dept-test functions. |
| GL_ARB_point_parameters |
| This is basically the same as GL_EXT_point_parameters. |
| GL_ARB_texture_env_crossbar |
| Allows any texture combine stage to reference any texture source unit. |
| GL_NV_point_sprite |
| For rendering points as textured quads. Useful for particle effects. |
| GL_NV_texture_rectangle (new in 4.0.4 actually) |
| Allows one to use textures with sizes that are not powers of two. |
| Note that mipmapping and several texture wrap modes are not allowed. |
| GL_EXT_multi_draw_arrays |
| Allows arrays of vertex arrays to be rendered with one call. |
| GL_EXT_stencil_two_side |
| Separate stencil modes for front and back-facing polygons. |
| GLX_SGIX_fbconfig & GLX_SGIX_pbuffer |
| Off-screen rendering support. |
| GL_ATI_texture_mirror_once |
| Adds two new texture wrap modes: GL_MIRROR_CLAMP_ATI and |
| GL_MIRROR_CLAMP_TO_EDGE_ATI. |
| Device Driver Status |

| New features in GLUT |
| -------------------- |
| 1. Frames per second printing |
| GLUT now looks for an environment variable called "GLUT_FPS". If it's |
| set, GLUT will print out a frames/second statistic to stderr when |
| glutSwapBuffers() is called. By default, frames/second is computed |
| and displayed once every 5 seconds. You can specify a different |
| interval (in milliseconds) when you set the env var. For example |
| 'export GLUT_FPS=1000' or 'setenv GLUT_FPS 1000' will set the interval |
| to one second. |
| NOTE: the demo or application must call the glutInit() function for |
| this to work. Otherwise, the env var will be ignored. |
| Finally, this feature may not be reliable in multi-window programs. |
| 2. glutGetProcAddress() function |
| The new function: |
| void *glutGetProcAddress(const char *procName) |
| is a wrapper for glXGetProcAddressARB() and wglGetProcAddress(). It |
| lets you dynamically get the address of an OpenGL function at runtime. |
| The GLUT_API_VERSION has been bumped to 5, but I haven't bumped the |
| GLUT version number from 3.7 since that's probably Mark Kilgard's role. |
| This function should probably also be able to return the address of |
| GLUT functions themselves, but it doesn't do that yet. |
| XXX Things To Do Yet XXXX |
| ------------------------- |
| isosurf with vertex program exhibits some missing triangles (probably |
| when recycling the vertex buffer for long prims). |
| Porting Info |
| ------------ |
| If you're porting a DRI or other driver from Mesa 4.0.x to Mesa 4.1 here |
| are some things to change: |
| 1. ctx->Texture._ReallyEnabled is obsolete. |
| Since there are now 5 texture targets (1D, 2D, 3D, cube and rect) that |
| left room for only 6 units (6*5 < 32) in this field. |
| This field is being replaced by ctx->Texture._EnabledUnits which has one |
| bit per texture unit. If the bit k of _EnabledUnits is set, that means |
| ctx->Texture.Unit[k]._ReallyEnabled is non-zero. You'll have to look at |
| ctx->Texture.Unit[k]._ReallyEnabled to learn if the 1D, 2D, 3D, cube or |
| rect texture is enabled for unit k. |
| This also means that the constants TEXTURE1_*, TEXTURE2_*, etc are |
| obsolete. |
| The tokens TEXTURE0_* have been replaced as well (since there's no |
| significance to the "0" part: |
| old token new token |
| TEXTURE0_1D TEXTURE_1D_BIT |
| TEXTURE0_2D TEXTURE_2D_BIT |
| TEXTURE0_3D TEXTURE_3D_BIT |
| TEXTURE0_CUBE TEXTURE_CUBE_BIT |
| <none> TEXTURE_RECT_BIT |
| These tokens are only used for the ctx->Texture.Unit[i].Enabled and |
| ctx->Texture.Unit[i]._ReallyEnabled fields. Exactly 0 or 1 bits will |
| be set in _ReallyEnabled at any time! |
| Q: "What's the purpose of Unit[i].Enabled vs Unit[i]._ReallyEnabled?" |
| A: The user can enable GL_TEXTURE_1D, GL_TEXTURE_2D, etc for any |
| texure unit all at once (an unusual thing to do). |
| OpenGL defines priorities that basically say GL_TEXTURE_2D has |
| higher priority than GL_TEXTURE_1D, etc. Also, just because a |
| texture target is enabled by the user doesn't mean we'll actually |
| use that texture! If a texture object is incomplete (missing mip- |
| map levels, etc) it's as if texturing is disabled for that target. |
| The _ReallyEnabled field will have a bit set ONLY if the texture |
| target is enabled and complete. This spares the driver writer from |
| examining a _lot_ of GL state to determine which texture target is |
| to be used. |
| 2. Tnl tokens changes |
| During the implementation of GL_NV_vertex_program some of the vertex |
| buffer code was changed. Specifically, the VERT_* bits defined in |
| tnl/t_context.h have been renamed to better match the conventions of |
| GL_NV_vertex_program. The old names are still present but obsolete. |
| Drivers should use the newer names. |
| For example: VERT_RGBA is now VERT_BIT_COLOR0 and |
| VERT_SPEC_RGB is now VERT_BIT_COLOR1. |
| 3. Read/Draw Buffer changes |
| The business of setting the current read/draw buffers in Mesa 4.0.x |
| was complicated. It's much simpler now in Mesa 4.1. |
| Here are the changes: |
| - Renamed ctx->Color.DrawDestMask to ctx->Color._DrawDestMask |
| - Removed ctx->Color.DriverDrawBuffer |
| - Removed ctx->Pixel.DriverReadBuffer |
| - Removed ctx->Color.MultiDrawBuffer |
| - Removed ctx->Driver.SetDrawBuffer() |
| - Removed swrast->Driver.SetReadBuffer(). |
| - Added ctx->Color._DrawDestMask - a bitmask of FRONT/BACK_LEFT/RIGHT_BIT |
| values to indicate the current draw buffers. |
| - Added ctx->Pixel._ReadSrcMask to indicate the source for pixel reading. |
| The value is _one_ of the FRONT/BACK_LEFT/RIGHT_BIT values. |
| - Added ctx->Driver.DrawBuffer() and ctx->Driver.ReadBuffer(). |
| These functions exactly correspond to glDrawBuffer and glReadBuffer calls. |
| Many drivers will set ctx->Driver.DrawBuffer = _swrast_DrawBuffer and |
| leave ctx->Draw.ReadBuffer NULL. |
| DRI drivers should implement their own function for ctx->Driver.DrawBuffer |
| and use it to set the current hardware drawing buffer. You'll probably |
| also want to check for GL_FRONT_AND_BACK mode and fall back to software. |
| Call _swrast_DrawBuffer() too, to update the swrast state. |
| - Added swrast->Driver.SetBuffer(). |
| This function should be implemented by all device drivers that use swrast. |
| Mesa will call it to specify the buffer to use for span reading AND |
| writing and point/line/triangle rendering. |
| There should be no confusion between current read or draw buffer anymore. |
| - Added swrast->CurrentBuffer to indicate which color buffer to read/draw. |
| Will be FRONT_LEFT_BIT, BACK_LEFT_BIT, FRONT_RIGHT_BIT or BACK_RIGHT_BIT. |
| This value is usually passed to swrast->Driver.SetBuffer(). |
| 4. _mesa_create_context() changes. This function now takes a pointer to |
| a __GLimports object. The __GLimports structure contains function |
| pointers to system functions like fprintf(), malloc(), etc. |
| The _mesa_init_default_imports() function can be used to initialize |
| a __GLimports object. Most device drivers (like the DRI drivers) |
| should use this. |
| 5. In tnl's struct vertex_buffer, the field "ProjectedClipCoords" |
| has been replaced by "NdcPtr" to better match the OpenGL spec's |
| terminology. |
| 6. Since GL_EXT_stencil_two_side has been implemented, many of the |
| ctx->Stencil fields are now 2-element arrays. For example, |
| "GLenum Ref" is now "GLenum Ref[2]" The [0] elements are the front-face |
| values and the [1] elements are the back-face values. |
| ctx->Stencil.ActiveFace is 0 or 1 to indicate the current face for |
| the glStencilOp/Func/Mask() functions. |
| ctx->Stencil.TestTwoSide controls whether or not 1 or 2-sided stenciling |
| is enabled. |
| 7. Removed ctx->Polygon._OffsetAny. Removed ctx->Polygon.OffsetMRD. |
| 8. GLfloat / GLchan changes: |
| - Changed ctx->Driver.ClearColor() to take GLfloat[4] instead of GLchan[4]. |
| ctx->Color.ClearColor is now GLfloat[4] too. |
| - Changed ctx->Driver.AlphaRef() to take GLfloat instead of GLchan. |
| - ctx->Color.AlphaRef is now GLfloat. |
| - texObj->BorderColor is now GLfloat[4]. texObj->_BorderChan is GLchan[4]. |
| This is part of an effort to remove all GLchan types from core Mesa so |
| that someday we can support 8, 16 and 32-bit color channels dynamically |
| at runtime, instead of at compile-time. |
| 9. GLboolean ctx->Tranform.ClipEnabled[MAX_CLIP_PLANES] has been replaced |
| by GLuint ctx->Transform.ClipPlanesEnabled. The later is a bitfield. |
| 10. There's a new matrix_stack type in mtypes.h used for the Modelview, |
| Projection, Color and Texcoord matrix stacks. |
| 11. The ctx->Current.* fields have changed a lot. Now, there's a |
| ctx->Current.Attrib[] array for all vertex attributes which matches |
| the NV vertex program conventions. |

| December 17, 2003 |
| PLEASE READ!!!! |
| Introduction |
| ------------ |
| Mesa uses an even/odd version number scheme like the Linux kernel. |
| Even-numbered versions (such as 5.0) designate stable releases. |
| Odd-numbered versions (such as 5.1) designate new developmental releases. |
| Bug fixes |
| --------- |
| See the VERSIONS file for a list of bugs fixed in this release. |
| New Features in Mesa 5.1 |
| ------------------------ |
| GL_ARB_vertex_program / GL_ARB_fragment_program |
| Michal Krol and Karl Rasche implemented these extensions. Thanks! |
| Be aware that there may be some rough edges and lurking bugs. |
| GL_ATI_texture_env_combine3 extension |
| This adds a few new texture combine modes. |
| Contributed by Ian Romanick. |
| GL_SGI_texture_color_table |
| Adds a color table lookup to the RGBA texture path. There's a separate |
| color table for each texture unit. |
| Contributed by Eric Plante. |
| GL_NV_fragment_program |
| NVIDIA's fragment-level programming feature. |
| Possible lurking bugs: |
| - the DDX and DDY commands aren't fully tested |
| - there may be bugs in the parser |
| - the TEX and TXP instructions both do perspective correction |
| - the pack/unpack instructions may not be correct |
| GL_EXT_depth_bounds_test |
| This extension adds a scissor-like test for the Z axis. It's used to |
| optimize stencil-volume shadow algorithms. |
| GL_NV_light_max_exponent |
| Lifts the 128 limit for max light exponent. |
| GL_EXT_texture_rectangle |
| Identical to GL_NV_texture_rectangle |
| GL_ARB_occlusion_query |
| Useful for visibility-based culling. |
| GL_ARB_texture_non_power_of_two |
| Removes the restriction that texture dimensions must be powers of two. |
| GL_ARB_vertex_buffer_object |
| Allows server-side vertex arrays, optimized host/card data transfers, etc. |
| GL_ARB_point_sprite |
| ARB-approved version of GL_NV_point_sprite. Basically allows textures |
| to be applied to points. |
| GL_IBM_multimode_draw_arrays |
| Allows multiple vertex arrays to be drawn with one call, including arrays |
| of different types of primitives. |
| GL_SUN_multi_draw_arrays |
| An alias for GL_EXT_multi_draw_arrays, standard in OpenGL 1.4. |
| Faster glDrawPixels / glCopyPixels in X11 driver |
| If your X screen is 32bpp, glDrawPixels to the front color buffer will |
| be accelerated (via XPutImage()) if the image format is GL_BGRA and the |
| type is GL_UNSIGNED_BYTE. No raster operations, such as depth test, |
| blend, fog, etc. can be enabled. |
| If your X screen is 16bpp, glDrawPixels to the front color buffer will |
| be accelerated (via XPutImage()) if the image format is GL_RGB and the |
| type is GL_UNSIGNED_SHORT_5_6_5. No raster operations, such as depth |
| test, blend, fog, etc. can be enabled. |
| glCopyPixels() calls for the front color buffer will be accelerated |
| (via XCopyArea()) if no raster operations, such as depth test, blend, |
| fog, pixel zoom, etc. are enabled. |
| The speed-up over typical software rendering is a factor of 10 for |
| glDrawPixels and 100 for glCopyPixels. |
| With the addition of GL_ARB_occlusion_query, GL_ARB_vertex_buffer_object, |
| GL_ARB_texture_non_power_of_two and GL_EXT_shadow_funcs, Mesa 5.1 supports |
| all the new features of OpenGL 1.5. Mesa 6.0 (the next stable release) |
| will advertise GL_VERSION = "1.5". |
| Vertex/Fragment program debugger |
| -------------------------------- |
| GL_MESA_program_debug is an experimental extension to support |
| interactive debugging of vertex and fragment programs. See the |
| docs/specs/OLD/MESA_program_debug.spec file for details. |
| The bulk of the vertex/fragment program debugger is implemented |
| outside of Mesa. The GL_MESA_program_debug extension just has minimal |
| hooks for stopping running programs and inspecting programs. |
| The progs/tests/debugger.c (only in CVS) program is an example of how |
| the extension can be used. Presently, the debugger code and demo code |
| is in the same file. Eventually the debugger code should be moved |
| into a reusable module. |
| As it is now, the demo lets you set breakpoings in vertex/fragment |
| programs, single step, and print intermediate register values. It's |
| basically just a proof of concept. |
| Directory tree reorganization |
| ----------------------------- |
| The directory structure for Mesa has been overhauled to improve its layout. |
| All source code for Mesa, GLU, GLUT, etc is now under the src/ directory |
| in appropriate subdirectories. |
| The Mesa source code and drivers has been reorganized under src/mesa/. |
| All demonstration programs and tests are now in subdirectories under progs/. |
| Build System Changes |
| -------------------- |
| The GNU automake/autoconf support has been removed. As it was, it seldom |
| worked on anything but Linux. The Mesa developers aren't big fans of |
| automake/autoconf/libtool and didn't have the time to maintain it. |
| If someone wants to contribute new automake/autoconf support (and is |
| willing to maintain it), it may be re-incorporated into Mesa, subject |
| to some requirements. |
| The "old style" makefile system has been updated: |
| 1. Make-config has been trimmed down to fewer, modern configurations. |
| 2. Most of the bin/mklib.* scripts have been rolled into a new "mklib" |
| script that works on all sorts of systems. There are probably some |
| bugs in it, but it's been tested on Linux, SunOS 5.8 and IRIX 6.5. |
| Improvements/contributes are greatly appreciated. |
| 3. The Makefile.X11 files have been cleaned up in various ways |
| Source File Changes |
| ------------------- |
| The mmath.[ch] files are obsolete. Their contents have been moved |
| into the imports.[ch] and macros.[ch] files. |
| The files related to vertex and fragment programming have changed. |
| Old files: |
| vpexec.[ch] |
| vpparse.[ch] |
| vpstate.[ch] |
| New files: |
| program.[ch] - generic ARB/NV program code |
| arbprogram.[ch] - ARB program API functions |
| arbfragparse.[ch] - ARB fragment program parsing |
| arbvertparse.[ch] - ARB vertex program parsing |
| arbparse.[ch] - ARB vertex/fragment parsing |
| arbparse_syn.h - vertex/fragment program syntax |
| nvprogram.[ch] - NV program API functions |
| nvvertprog.h - NV vertex program definitions |
| nvfragprog.h - NV fragment program definitions |
| nvvertparse.[ch] - NV vertex program parser |
| nvfragparse.[ch] - NV fragment program parser |
| nvvertexec.[ch] - NV vertex program execution |
| swrast/s_nvfragprog.[ch] - NV fragment program execution |
| The files related to per-vertex handling have changed. |
| Old files: |
| tnl/t_eval_api.c - old per-vertex code |
| tnl/t_imm_alloc.c - old per-vertex code |
| tnl/t_imm_api.c - old per-vertex code |
| tnl/t_imm_debug.c - old per-vertex code |
| tnl/t_imm_dlist.c - old per-vertex code |
| tnl/t_imm_elt.c - old per-vertex code |
| tnl/t_imm_eval.c - old per-vertex code |
| tnl/t_imm_exec.c - old per-vertex code |
| tnl/t_imm_fixup.c - old per-vertex code |
| tnl/t_vtx_sse.c - old per-vertex code |
| tnl/t_vtx_x86.c - old per-vertex code |
| New files: |
| tnl/t_save_api.c - new per-vertex code |
| tnl/t_save_loopback.c - new per-vertex code |
| tnl/t_save_playback.c - new per-vertex code |
| tnl/t_vtx_eval.c - old per-vertex code |
| Other new files: |
| bufferobj.[ch] - GL_ARB_vertex_buffer_object functions |
| version.h - defines the Mesa version info |
| Other removed files: |
| swrast/s_histogram.[ch] - moved into src/histogram.c |
| Other Changes |
| ------------- |
| The ctx->Driver.CreateTexture function has been removed - it wasn't used. |
| New device driver hook functions: |
| NewTextureObject - used to allocate struct gl_texture_objects |
| NewTextureImage - used to allocate struct gl_texture_images |
| New ctx->Texture._EnabledCoordUnits field: |
| With the addition of GL_NV_fragment_program we may need to interpolate |
| various sets of texture coordinates even when the corresponding texture |
| unit is not enabled. That is, glEnable(GL_TEXTURE_xD) may never get |
| called but we still may have to interpolate texture coordinates across |
| triangles so that the fragment program will get them. |
| This new field indicates which sets of texture coordinates are needed. |
| If a bit is set in the ctx->Texture._EnabledUnits bitmask is set, the |
| same bit MUST be set in ctx->Texture._EnabledCoordUnits. |
| The ctx->_TriangleCaps field is deprecated. |
| Instead of testing the DD_* bits in _TriangleCaps, you should instead |
| directly test the relevant state variables, or use one of the helper |
| functions like NEED_SECONDARY_COLOR() at the bottom of context.h |
| While testing _TriangleCaps bits was fast, it was kludgey, and setting |
| the bits in the first place could be error prone. |
| New vertex processing code. |
| The code behind glBegin, glEnd, glVertex, glNormal, etc. has been |
| totally rewritten. It's a cleaner implementation now and should use |
| less memory. (Keith) |
| To Do |

| Add screen-awareness to fakeglx.c |

| Mesa 6.0 release notes |
| January 16, 2004 |
| PLEASE READ!!!! |
| Introduction |
| ------------ |
| Mesa uses an even/odd version number scheme like the Linux kernel. |
| Odd numbered versions (such as 5.1) designate new developmental releases. |
| Even numbered versions (such as 6.0) designate stable releases. |
| Mesa version 6.0 signifies two things: |
| 1. A stabilization of the 5.1 development release |
| 2. Implementation of the OpenGL 1.5 specification. When you query |
| glGetString(GL_VERSION) "1.5" will be returned (as long as the |
| driver supports all the required features). |
| Note that the Mesa major version number is incremented with the OpenGL |
| minor version number: |
| Mesa 1.x == OpenGL 1.0 |
| Mesa 2.x == OpenGL 1.1 |
| Mesa 3.x == OpenGL 1.2 |
| Mesa 4.x == OpenGL 1.3 |
| Mesa 5.x == OpenGL 1.4 |
| Mesa 6.x == OpenGL 1.5 |
| New Features |
| ------------ |
| Mesa 5.1 already had all the new features of OpenGL 1.5, implemented as |
| extensions. These extensions were simply promoted to standard features: |
| GL_ARB_occlusion_query extension |
| GL_ARB_texture_non_power_of_two extension |
| GL_ARB_vertex_buffer_object extension |
| GL_EXT_shadow_funcs |
| Device Drivers |
| -------------- |
| Mesa advertises itself as either OpenGL 1.2 or OpenGL 1.3 depending on |
| the device driver. For example, if the driver enables all the ARB |
| extensions which are part of OpenGL 1.3 then glGetString(GL_VERSION) |
| will return "1.3". Otherwise, it'll return "1.2". |
| A number of Mesa's software drivers haven't been actively maintained for |
| some time. We rely on volunteers to maintain many of the drivers. |
| Here's the current status of all included drivers: |
| Driver Status |

| Mesa 6.0.1 release notes |
| April 2, 2003 |
| Introduction |
| ------------ |
| Mesa uses an even/odd version number scheme like the Linux kernel. |
| Even-numbered versions (such as 6.0.x) designate stable releases. |
| Odd-numbered versions (such as 6.1.x) designate new developmental releases. |
| Mesa 6.0.1 just fixes bugs found since the 6.0 release. See the VERSIONS |
| file for details. |
| Device Drivers |
| -------------- |
| Mesa advertises itself as supporting OpenGL 1.2, 1.3, 1.4 or 1.5 |
| depending on the device driver's capabilities. For example, if the |
| driver enables all the ARB extensions which are part of OpenGL 1.5 |
| then glGetString(GL_VERSION) will return "1.5". Otherwise, it'll |
| return "1.4" or the next lower version that implements all required |
| functionality. |
| A number of Mesa's software drivers haven't been actively maintained for |
| some time. We rely on volunteers to maintain many of the drivers. |
| Here's the current status of all included drivers: |
| Driver Status |
| ---------------------- --------------------- |
| XMesa (Xlib) implements OpenGL 1.5 |
| OSMesa (off-screen) implements OpenGL 1.5 |
| FX (3dfx Voodoo1/2) implements OpenGL 1.3 |

| Wind River UGL implements OpenGL 1.3 |
| Windows/Win32 implements OpenGL 1.5 |
| DJGPP implements OpenGL 1.5 |
| GGI implements OpenGL 1.3 |

| Mesa 6.1 release notes |
| August 18, 2004 |
| PLEASE READ!!!! |
| Introduction |
| ------------ |
| Mesa uses an even/odd version number scheme like the Linux kernel. |
| Odd numbered versions (such as 6.1) designate new developmental releases. |
| Even numbered versions (such as 6.0) designate stable releases. |
| New Features |
| ------------ |
| Half-precision floating point (GLhalf) pixel formats are supported |
| in Mesa, but the feature isn't exposed yet since the ARB extension |
| hasn't been finalized yet. |
| Texture image handling |
| ---------------------- |
| The code which implements image conversion, pixel transfer ops, etc |
| for glTexImage commands has been rewritten. |
| Now the gl_texture_format struct has a new StoreImage function |
| pointer. Each texture format must implement this function. The |
| function is totally responsible for converting the user's texture |
| image into the specific format. A few helper functions makes this |
| relatively simple. |
| Overall, the code is much simpler, cleaner and easier to work with |
| now. Adding new texture formats is straight-forward and there's no |
| longer any distinction between "hardware" and "software" formats. |
| Finally, the code for compressed texture images has been reorganized |
| as well. |
| Removed files: |
| texutil.c |
| texutil.h |
| texutil_tmp.h |
| New files: |
| texcompress_s3tc.c |
| texcompress_fxt1.c |
| Driver / context changes |
| ------------------------ |
| The _mesa_create_context() and _mesa_initialize_context() function |
| parameters have changed. They now take a pointer to a struct |
| dd_function_table. Drivers can initialize this table by calling |
| _mesa_init_driver_functions(). Drivers should then plug in the special |
| functions they implement. In particular, the ctx->Driver.NewTextureObject |
| pointer _must_ be set so that the default texture objects created in |
| _mesa_create/initialize_context() are correctly built. |
| The _mesa_init_driver_functions() function allows a lot of redundant code |
| to be removed from the device drivers (such as initializing |
| ctx->Driver.Accum to point to _swrast_Accum). Adding new functions to |
| the dd_function_table can be done with less hassle since the pointer can |
| be initialized in _mesa_init_driver_functions() rather than in _all_ the |
| drivers. |
| Device Drivers |
| -------------- |
| Mesa advertises itself as supporting OpenGL 1.2, 1.3, 1.4 or 1.5 |
| depending on the device driver's capabilities. For example, if the |
| driver enables all the ARB extensions which are part of OpenGL 1.5 |

| return "1.4" or the next lower version that implements all required |

| Introduction |
| ------------ |
| Mesa uses an even/odd version number scheme like the Linux kernel. |
| Odd numbered versions (such as 6.1) designate new developmental releases. |
| Even numbered versions (such as 6.2) designate stable releases. |
| This release primarily just fixes bugs found in the Mesa 6.1 release. |
| See the VERSIONS file for details. |
| ToDo: PBO for polygon stipple, convolution filter, etc. |
| Known Issues |
| ------------ |
| The GL_EXT_pixel_buffer_object extension isn't fully implemented for |
| functions like glPolygonStipple, glConvolutionFilter, glColorTable, |
| etc. The important functions like glRead/DrawPixels, glTex[Sub]Image, |
| and glBitmap work with PBOs. |

| Mesa 6.3 release notes |
| July 20, 2005 |
| PLEASE READ!!!! |
| Introduction |
| ------------ |
| Mesa uses an even/odd version number scheme like the Linux kernel. |
| Odd numbered versions (such as 6.3) designate new developmental releases. |
| Even numbered versions (such as 6.2) designate stable releases. |
| New Features |
| ------------ |
| GL_ARB_draw_buffers - allows a fragment program to write to a number of |
| separate color buffers, instead of just one. |
| GL_OES_read_format - allows one to query the fastest glReadPixels format |
| and datatype. |
| GL_ARB_pixel_buffer_object - buffer objects for pixel read/write functions. |
| GL_EXT_framebuffer_object - allows render-to-texture and provides a |
| window-system indepedent Pbuffer facility. |
| The Mesa CVS tree contains a couple tests of this extension. |
| DirectFB driver, contributed by Claudio Ciccani. See docs/README.directfb |
| for details. |
| Vertex/Fragment Program PRINT Instruction |
| ----------------------------------------- |
| The GL_NV_vertex_program and GL_NV_fragment_program languages have been |
| extended with a PRINT instruction. |
| glDeleteTextures(), glDeletePrograms() and glDeleteBuffers() Changed |
| -------------------------------------------------------------------- |
| To match the behaviour of other OpenGL implementations, glDeleteTextures, |
| glDeletePrograms and glDeleteBuffers have been modified so that: |
| * The named texture/program/buffer ID is immediately freed for re-use. |
| * The actual texture object, program or buffers isn't really deleted until |
| it is no longer bound in any rendering context (the reference count |
| is zero). |
| Previously, the texture/program/buffer ID wasn't freed until the object |
| was really deleted. |
| Note that textures, programs and buffers can be shared by several rendering |
| contexts so they can't be deleted until they're unbound in _all_ contexts. |
| GL_EXT_framebuffer_object changes |
| --------------------------------- |
| Implementing this extension involved changing a lot of code (for the better). |
| The gl_framebuffer object now a collection of gl_renderbuffer objects. |
| Renderbuffers may store colors, stencil indices, or depth values. The |
| gl_framebuffer and gl_renderbuffer types are object-oriented in design. |
| All the old RGB, color index, stencil and depth-related span functions for |
| reading/writing pixels from/to buffers has changed. Now, all pixels are |
| read/written through a set of common renderbuffer functions (methods). |
| Most device drivers have been updated for these changes, but some haven't. |
| To Do (someday) items |
| --------------------- |
| Switch to freeglut |
| Increase MAX_DRAWBUFFERS |
| driver hooks for BeginQuery/EndQuery |
| Miscellaneous |
| ------------- |
| The main/get.c file is now generated with a Python script (get_gen.py). |

| </ul> |
| <h2>Bug fixes</h2> |
| <ul> |

| </pre> |
| <h2>Shared library numbering</h2> |
| <p> |
| Mesa 6.5.3 supports the OpenGL 2.0/2.1 API. However, the (unix) |
| shared library version is still 1.5 (i.e. libGL.so.1.5.xxxxxx). |
| Bumping the shared library version to 2.x would cause linking problems |
| with existing OpenGL applications. Since OpenGL 2.x is backward |
| compatible with OpenGL 1.x the shared library version number doesn't |
| have to be incremented (which would indicate an incompatible ABI). |
| </p> |
| <p> |
| Other OpenGL vendors name their OpenGL 2.x libraries libGL.so.1.0.xxxxx |
| for the same reason. |
| </p> |
| <h2>New features</h2> |
| <ul> |
| <li>OpenGL 2.0 and 2.1 API support. |
| <li>Entirely new Shading Language code generator. See the |
| <a href="../shading.html">Shading Language</a> page for more information. |
| <li>Much faster software execution of vertex, fragment shaders. |
| <li>New vertex buffer object (vbo) infrastructure |
| <li>Updated glext.h file (version 39) |
| <li>Updated glxext.h file (version 19) |
| <li>GL_MAX_DRAWBUFFERS is now 4 (software rendering) so |
| "multiple render targets" are really supported. |
| </ul> |
| <h2>Bug fixes</h2> |
| <ul> |
| <li>Fog was errantly applied when a fragment shader was enabled (bug 9346) |
| <li>glPush/PopClientAttrib didn't handle VBO bindings correctly (bug 9445) |
| <li>With 32-bit Z buffer, the fragment Z of lines and points was sometimes wrong. |
| <li>GL_POST_CONVOLUTION_ALPHA_BIAS/SCALE was broken. |
| <li>1D convolution state could effect 2D image transfers |
| <li>Overlapping glCopyPixels with negative Y zoom didn't work (bug 10521) |
| <li>Fixed a number of framebuffer/renderbuffer reference counting bugs |
| <li>Fixed a few bugs in software-emulated alpha planes |
| <li>Assorted minor bug fixes in glCopy/DrawPixels, glPixelZoom, etc. |
| <li>Assorted DRI driver bug fixes. |
| <li>Fixed a number of bugs that prevented "depth-peeling" rendering from working. |
| </ul> |
| <h2>Internal code changes</h2> |
| <ul> |
| <li>Old array_cache module replaced by new vbo module. All geometry |
| rendering is now cast in the form of vertex buffer objects. |
| <li>Massive changes to the Shading Language compiler and related state. |
| <li>Vertex/fragment shaders are compiled into GPU instructions and |
| programs very similar to GL_ARB_vertex/fragment_program. |
| <li>Vertex and fragment programs are executed with the same code now. |
| <li>The SSE-optimized vertex program path has been removed since it didn't |
| support more than 12 temp registers, didn't support branching/looping, etc. |
| </ul> |
| <h2>To Do (someday) items</h2> |
| <ul> |
| <li>Switch to freeglut |
| <li>Fix linux-glide target/driver. |
| <li>Improved lambda and derivative calculation for frag progs. |

| <h2>New Features</h2> |
| <ul> |
| <li>OpenGL Shading language support |
| <br> |
| This includes the GL_ARB_shader_objects, GL_ARB_shading_language_100, |
| GL_ARB_vertex_shader and GL_ARB_fragment_shader extensions. Most of |
| the work was done by Michal Krol. |
| There's probably a fair number of bugs since this is a pretty large, |
| complicated body of code. |
| <br> |
| The OpenGL 2.0 interface to these features will be implemented in a |
| future version of Mesa, |
| <li>GL_EXT_timer_query |
| <br> |
| Used to measure the time of OpenGL operations at high precision. |
| Only supported in the software/Xlib driver at this time. |

| <br> |
| Defines a new GL_DEPTH_STENCIL_EXT pixel format. |
| <li>GL_EXT_framebuffer_blit |
| <br> |
| A simplified glCopyPixels-like feature for copying pixel rectangles. |
| <li>GL_ARB_half_float_pixel |
| <br> |
| Adds a new half-precision floating point format for image transfers, |
| such as for glDrawPixels, glReadPixels, glTexImage, etc. |
| </ul> |
| <h2>Changes</h2> |
| <ul> |
| <li>removed GL_HP_occlusion_test (use GL_ARB_occlusion_query instead) |
| <li>removed GL_SGIX/SGIS_pixel_texture extensions |
| </ul> |
| <h2>Bug fixes</h2> |

| <li>fixed aix-gcc build/install bugs (bug 5874) |
| <li>fixed some bugs in texture env program generation |
| <li>glXCopyContext() didn't handle texture object bindings properly |
| <li>glXCopyContext() didn't copy all lighting state |
| <li>fixed FreeBSD config (Pedro Giffuni) |
| <li>fixed some minor framebuffer object bugs |
| <li>replaced dprintf() with _glu_printf() in GLU (bug 6244) |

| textures should work. |
| </ul> |
| <h2>Driver Interface Changes</h2> |
| <ul> |
| <li>Stencil: The Driver.StencilOp/Func/Mask() functions have been replaced by |
| the two-sided versions: Driver.Stencil*Separate(). |
| <li>Render-to-texture: The functions for rendering to textures have changed. |
| </ul> |
| <h2>To Do (someday) items</h2> |
| <ul> |
| <li>Switch to freeglut |
| <li>Increase MAX_DRAWBUFFERS |
| <li>Fix linux-glide target/driver. |

| <p> |
| Mesa 7.1 is a new development release. |
| There have been many internal code changes since Mesa 7.0.x. |
| It should be relatively stable, but those who are especially concerned about |
| stability should wait for Mesa 7.2 or use Mesa 7.0.4 (the previous stable |
| release). |
| </p> |
| <p> |
| Note that this version of Mesa does not use the GEM memory manager. |
| The master branch of git uses GEM. |
| </p> |
| <p> |
| DRM version 2.3.1 should be used with Mesa 7.1 |

| </pre> |
| <h2>New features</h2> |
| <ul> |
| <li>autoconf-based configuration (and clean-up of Makefiles) |
| <li>Assorted DRI driver enhancements |
| <li>Reduced dependencies between X server and Mesa |
| <li>GL_EXT_texture_from_pixmap extension for Xlib driver |
| <li>Support for the GL shading language with i965 driver (implemented by Intel) |
| <li>ATI R500 series support (Radeon X1300–X1950) in r300 DRI driver |
| </ul> |
| <h2>Bug fixes</h2> |
| <ul> |
| <li>Numerous GLSL fixes |
| <li>Fixed some error code/detection bugs in the GLSL-related API functions |
| <li>Lots of DRI driver fixes. |
| </ul> |
| <h2>To Do (someday) items</h2> |
| <ul> |
| <li>Remove the MEMCPY() and _mesa_memcpy() wrappers and just use memcpy(). |
| Probably do the same for malloc, calloc, etc. |
| The wrappers were useful in the past for memory debugging but now we |
| have valgrind. Not worried about SunOS 4 support anymore either... |
| <li>Switch to freeglut |
| <li>Fix linux-glide target/driver. |
| <li>Improved lambda and derivative calculation for frag progs. |
| </ul> |
| <h2>Driver Status</h2> |

| <h1>Mesa 7.10.1 Release Notes / March 2, 2011</h1> |
| <p> |
| Mesa 7.10.1 is a bug fix release which fixes bugs found since the 7.10 release. |
| </p> |
| <p> |
| Mesa 7.10.1 implements the OpenGL 2.1 API, but the version reported by |
| glGetString(GL_VERSION) depends on the particular driver being used. |
| Some drivers don't support all the features required in OpenGL 2.1. |
| </p> |
| <p> |
| See the <a href="../install.html">Compiling/Installing page</a> for prerequisites |
| for DRI hardware acceleration. |

| <h1>Mesa 7.10.2 Release Notes / April 6, 2011</h1> |
| <p> |
| Mesa 7.10.2 is a bug fix release which fixes bugs found since the 7.10 release. |
| </p> |
| <p> |
| Mesa 7.10.2 implements the OpenGL 2.1 API, but the version reported by |
| glGetString(GL_VERSION) depends on the particular driver being used. |
| Some drivers don't support all the features required in OpenGL 2.1. |
| </p> |
| <p> |
| See the <a href="../install.html">Compiling/Installing page</a> for prerequisites |
| for DRI hardware acceleration. |

| <h1>Mesa 7.10 Release Notes / January 7, 2011</h1> |
| <p> |
| Mesa 7.10 is a new development release. |
| People who are concerned with stability and reliability should stick |
| with a previous release or wait for Mesa 7.10.1. |
| </p> |
| <p> |
| Mesa 7.10 implements the OpenGL 2.1 API, but the version reported by |
| glGetString(GL_VERSION) depends on the particular driver being used. |
| Some drivers don't support all the features required in OpenGL 2.1. |
| </p> |
| <p> |
| See the <a href="../install.html">Compiling/Installing page</a> for prerequisites |
| for DRI hardware acceleration. |
| </p> |

| <h1>Mesa 7.11.1 Release Notes / November 17, 2011</h1> |
| <p> |
| Mesa 7.11.1 is a bug fix release which fixes bugs found since the 7.11 release. |
| </p> |
| <p> |
| Mesa 7.11 implements the OpenGL 2.1 API, but the version reported by |
| glGetString(GL_VERSION) depends on the particular driver being used. |
| Some drivers don't support all the features required in OpenGL 2.1. |
| </p> |
| <p> |
| See the <a href="../install.html">Compiling/Installing page</a> for prerequisites |
| for DRI hardware acceleration. |

| <h2>Changes</h2> |
| <ul> |
| <li>The Windows MSVC project files have been removed. |
| They haven't been maintained in quite a while. |
| Building with SCons is an alternative. |
| <li>Removed GL_SGI_texture_color_table support from swrast driver - the only |

| <h1>Mesa 7.2 Release Notes / 20 September 2008</h1> |
| <p> |
| Mesa 7.2 is a stable release fixing bugs found in 7.1, which was a |
| new development release. |
| </p> |
| <p> |
| Mesa 7.2 implements the OpenGL 2.1 API, but the version reported by |
| glGetString(GL_VERSION) depends on the particular driver being used. |
| Some drivers don't support all the features required in OpenGL 2.1. |
| </p> |
| <p> |
| Note that this version of Mesa does not use the GEM memory manager. |
| The master branch of git uses GEM. |
| The prototype DRI2 code that was in 7.1 has also been removed. |
| </p> |
| <p> |
| DRM version 2.3.1 should be used with Mesa 7.2 |

| <h2>New features</h2> |
| <ul> |
| <li>i965 driver: added support for G41 chipset (Intel) |
| </ul> |
| <h2>Bug fixes</h2> |
| <ul> |
| <li>Fixed display list bug involving primitives split across lists (bug 17564) |
| <li>Fixed some issues with glBindAttribLocation() |
| <li>Fixed crash in _tnl_InvalidateState() found with Amira (bug 15834) |
| <li>Assorted bug fixes for Ming build |
| <li>Fixed some vertex/pixel buffer object reference counting bugs |
| <li>Fixed depth/stencil bug in i915/945 driver |
| <li>Fixed some shader flow control bugs in i965 driver |
| <li>Fixed a few tdfx driver bugs which prevented driver from working |
| <li>Fixed multisample enable/disable bug |
| </ul> |
| <h2>Changes</h2> |
| <ul> |
| <li>Updated SGI header files with new license terms. |
| </ul> |
| <h2>To Do (someday) items</h2> |
| <ul> |
| <li>Remove the MEMCPY() and _mesa_memcpy() wrappers and just use memcpy(). |
| Probably do the same for malloc, calloc, etc. |
| The wrappers were useful in the past for memory debugging but now we |
| have valgrind. Not worried about SunOS 4 support anymore either... |
| <li>Switch to freeglut |
| <li>Fix linux-glide target/driver. |
| <li>Improved lambda and derivative calculation for frag progs. |
| </ul> |

| <h1>Mesa 7.5 Release Notes / 17 July 2009</h1> |
| <p> |
| Mesa 7.5 is a new development release. |
| People who are concerned with stability and reliability should stick |
| with the 7.4.x branch or wait for Mesa 7.5.1. |
| </p> |
| <p> |
| The main new feature of Mesa 7.5 is the |

| <p> |
| Note that the Mesa project is no longer using odd/even version numbers |
| to indicate development/stable releases. |
| The so-called development releases have been fairly stable. |
| If you're especially concerned with stability you should probably look for |
| "point" releases such as 7.5.1 which will be a bug-fix release. |

| <h2>New features</h2> |
| <ul> |
| <li>Gallium3D - this is the new architecture for OS-independent and |
| API-independent 3D drivers. |
| Gallium3D is intended for GPUs that fully support vertex/fragment shaders. |
| The Gallium3D drivers currently included are: |
| <ul> |
| <li>softpipe - a software/reference driver |
| <li>i915 - Intel 915/945 driver |
| <li>Cell - IBM/Sony/Toshiba Cell processor driver |
| <li>nouveau (for NVIDIA GPUs) and R300 for (AMD/ATI R300). |
| <b>PLEASE NOTE: these drivers are incomplete and still under development. |
| It's probably NOT worthwhile to report any bugs unless you have patches. |
| </b> |
| </ul> |
| <li>GL_ARB_framebuffer_object extension (software drivers, i965 driver) |
| <li>Reworked two-sided stencil support. |
| This allows a driver to support all three variations of two-sided stencil |
| including GL_ATI_separate_stencil, GL_EXT_stencil_two_side and OpenGL 2.0 |
| <li>GL_EXT_vertex_array_bgra extension (software drivers, i965 driver) |
| <li>GL_NV_texture_env_combine4 extension (software drivers, i965/i915 drivers) |
| <li>GL_EXT_texture_swizzle extension (software drivers, i965 driver) |
| <li>Updated SPARC assembly optimizations (David S. Miller) |
| <li>Initial support for separate compilation units in GLSL compiler. |
| <li>Increased max number of generic GLSL varying variables to 16 (formerly 8). |
| <li>GLSL linker now detects when too many varying variables are used. |
| <li>Optimize-out redundant glMaterial and glShadeModel calls in display lists |
| <li>Fixed gl_TextureMatrix[i][j] array indexing bug in GLSL compiler. |
| </ul> |
| <h2>Bug fixes</h2> |
| <ul> |
| <li>Lots of i965 driver bug fixes |
| <li>Fixed some GLSL preprocessor bugs |
| <li>GLSL: continue inside of a for-loop didn't work |
| </ul> |
| <h2>Changes</h2> |
| <ul> |
| <li>Remove support for GL_SGIX_shadow, GL_SGIX_shadow_ambient and |
| GL_SGIX_depth_texture extensions. Superseded by the ARB versions. |
| <li>Omitted some old Mesa demos from the release tarballs, added some others. |

| <h1>Mesa 7.9.1 Release Notes / January 7, 2011</h1> |
| <p> |
| Mesa 7.9.1 is a bug fix release which fixes bugs found since the 7.9 release. |
| </p> |
| <p> |
| Mesa 7.9.1 implements the OpenGL 2.1 API, but the version reported by |
| glGetString(GL_VERSION) depends on the particular driver being used. |
| Some drivers don't support all the features required in OpenGL 2.1. |
| </p> |
| <p> |
| See the <a href="../install.html">Compiling/Installing page</a> for prerequisites |
| for DRI hardware acceleration. |

| <h1>Mesa 8.0.5 Release Notes / October 24, 2012</h1> |
| <p> |
| Mesa 8.0.5 is a bug fix release which fixes bugs found since the 8.0.4 release. |
| </p> |
| <p> |
| Mesa 8.0.5 implements the OpenGL 3.0 API, but the version reported by |
| glGetString(GL_VERSION) depends on the particular driver being used. |
| Some drivers don't support all the features required in OpenGL 3.0. |
| </p> |
| <p> |
| See the <a href="../install.html">Compiling/Installing page</a> for prerequisites |
| for DRI hardware acceleration. |

| <h1>Mesa 8.0 Release Notes / February 9, 2012</h1> |
| <p> |
| Mesa 8.0 is a new development release. |
| People who are concerned with stability and reliability should stick |
| with a previous release or wait for Mesa 8.0.1. |
| </p> |
| <p> |
| Mesa 8.0 implements the OpenGL 3.0 API, but the version reported by |
| glGetString(GL_VERSION) depends on the particular driver being used. |
| Some drivers don't support all the features required in OpenGL 3.0. |
| </p> |

| See the <a href="../install.html">Compiling/Installing page</a> for prerequisites |
| for DRI hardware acceleration. |

| <li>GL_ARB_depth_buffer_float (r600g) |
| <li>GL_ARB_vertex_type_2_10_10_10_rev (r600g) |

| <li>Many updates to the VMware svga Gallium driver |
| </ul> |
| <h2>Bug fixes</h2> |
| <h2>Changes</h2> |
| <ul> |
| <li>Removed all DRI drivers that did not support DRI2. Specifically, |
| i810, mach64, mga, r128, savage, sis, tdfx, and unichrome were |
| removed.</li> |
| <li>Removed support for BeOS.</li> |
| <li>Removed the obsolete (and unmaintained) Windows "gldirect" and |
| "ICD" drivers.</li> |
| <li>Removed the linux-fbdev software driver.</li> |
| <li>Removed all remnants of paletted texture support. As required by |
| desktop OpenGL, <tt>GL_COLOR_INDEX</tt> data can still be uploaded |
| to a color (e.g., RGBA) texture. However, the data cannot be stored |
| internally as color-index.</li> |
| <li>Removed support for GL_APPLE_client_storage extension.</li> |
| <li>Removed the classic Mesa r300 and r600 drivers, which are superseded |
| by the gallium drivers for this hardware.</li> |
| <li>Removed the dead Gallium i965, cell and failover drivers, which were |
| either broken and with nobody in sight to fix the situation or |
| deprecated.</li> |

| <h1>Mesa 9.0.2 Release Notes / January 22th, 2013</h1> |
| <p> |
| Mesa 9.0.2 is a bug fix release which fixes bugs found since the 9.0.1 release. |
| </p> |
| <p> |
| Mesa 9.0 implements the OpenGL 3.1 API, but the version reported by |
| glGetString(GL_VERSION) or glGetIntegerv(GL_MAJOR_VERSION) / |
| glGetIntegerv(GL_MINOR_VERSION) depends on the particular driver being used. |
| Some drivers don't support all the features required in OpenGL 3.1. OpenGL |
| 3.1 is <strong>only</strong> available if requested at context creation |
| because GL_ARB_compatibility is not supported. |

| <h1>Mesa 9.0 Release Notes / October 8, 2012</h1> |
| <p> |
| Mesa 9.0 is a new development release. |
| People who are concerned with stability and reliability should stick |
| with a previous release or wait for Mesa 9.0.1. |
| </p> |
| <p> |
| Mesa 9.0 implements the OpenGL 3.1 API, but the version reported by |
| glGetString(GL_VERSION) or glGetIntegerv(GL_MAJOR_VERSION) / |
| glGetIntegerv(GL_MINOR_VERSION) depends on the particular driver being used. |
| Some drivers don't support all the features required in OpenGL 3.1. OpenGL |
| 3.1 is <strong>only</strong> available if requested at context creation |
| because GL_ARB_compatibility is not supported. |
| </p> |

| <h2>Bug fixes</h2> |
| <p>TBD -- This list is likely incomplete.</p> |
| <h2>Changes</h2> |
| <ul> |
| <li> |

| <br> |
| The two supported build methods are now autoconf/automake and SCons. |
| </li> |
| <li>Removed support for GL_ARB_shadow_ambient extension</li> |
| <li>Removed Gallium3D - nvfx driver (use nv30 instead)</li> |
| <li> |

| <h1>Mesa 9.1.2 Release Notes / April 30th, 2013</h1> |
| <p> |
| Mesa 9.1.2 is a bug fix release which fixes bugs found since the 9.1.1 release. |
| </p> |
| <p> |
| Mesa 9.1 implements the OpenGL 3.1 API, but the version reported by |
| glGetString(GL_VERSION) or glGetIntegerv(GL_MAJOR_VERSION) / |
| glGetIntegerv(GL_MINOR_VERSION) depends on the particular driver being used. |
| Some drivers don't support all the features required in OpenGL 3.1. OpenGL |
| 3.1 is <strong>only</strong> available if requested at context creation |
| because GL_ARB_compatibility is not supported. |

| <h1>Mesa 9.1.4 Release Notes / July 1st, 2013</h1> |
| <p> |
| Mesa 9.1.4 is a bug fix release which fixes bugs found since the 9.1.3 release. |
| </p> |
| <p> |
| Mesa 9.1 implements the OpenGL 3.1 API, but the version reported by |
| glGetString(GL_VERSION) or glGetIntegerv(GL_MAJOR_VERSION) / |
| glGetIntegerv(GL_MINOR_VERSION) depends on the particular driver being used. |
| Some drivers don't support all the features required in OpenGL 3.1. OpenGL |
| 3.1 is <strong>only</strong> available if requested at context creation |
| because GL_ARB_compatibility is not supported. |
| </p> |

| Some drivers don't support all the features required in OpenGL 3.1. OpenGL |
| 3.1 is <strong>only</strong> available if requested at context creation |

| </ul> |
| <h2>Changes</h2> |
| <ul> |
| <li>Removed d3d1x state tracker (unused, unmaintained and broken)</li> |
| <li>Removed GL_EXT_clip_volume_hint because no driver had enabled it since |
| 2007.</li> |
| <li>Removed GL_MESA_resize_buffers because it was only really implemented by |
| the (unsupported) GDI driver.</li> |
| <li>GL_EXT_separate_shader_objects has been removed from all Gallium drivers, |
| because it disallows a critical GLSL shader optimization. |
| GL_ARB_separate_shader_objects doesn't have this issue.</li> |
| <li>i965 Gen6+ requires Kernel 3.6 or later. (92d2f5a)</li> |

| <a href="http://www.freedesktop.org/wiki/AccountRequests"> |
| procedure</a>. |
| </p> |
| <p> |
| Once your account is established: |
| </p> |
| <ol> |
| <li>Install the git software on your computer if needed.<br><br> |
| <li>Get an initial, local copy of the repository with: |
| <pre> |
| git clone git+ssh://username@git.freedesktop.org/git/mesa/mesa |
| </pre> |
| Replace <em>username</em> with your actual login name.<br><br> |
| <li>Later, you can update your tree from the master repository with: |
| <pre> |
| git pull origin |
| </pre> |
| <li>If you also want the Mesa demos/tests repository: |
| <pre> |
| git clone git+ssh://username@git.freedesktop.org/git/mesa/demos |
| </pre> |
| </ol> |
| <h2>Windows Users</h2> |
| <p> |
| If you're <a href="http://git.wiki.kernel.org/index.php/WindowsInstall"> |
| using git on Windows</a> you'll want to enable automatic CR/LF conversion in |
| your local copy of the repository: |
| </p> |
| <pre> |
| git config --global core.autocrlf true |
| </pre> |
| <p> |
| This will cause git to convert all text files to CR+LF on checkout, |
| and to LF on commit. |
| </p> |
| <p> |
| Unix users don't need to set this option. |
| </p> |
| <br> |
| <h2>Development Branches</h2> |
| <p> |
| At any given time, there may be several active branches in Mesa's |
| repository. |
| Generally, the trunk contains the latest development (unstable) |
| code while a branch has the latest stable code. |
| </p> |
| <p> |
| The command <code>git-branch</code> will list all available branches. |
| </p> |
| <p> |
| Questions about branch status/activity should be posted to the |
| mesa3d-dev mailing list. |
| </p> |
| <h2>Developer Git Tips</h2> |
| <ol> |
| <li>Setting up to edit the master branch |
| <p> |
| If you try to do a pull by just saying<code> git pull </code> |
| and git complains that you have not specified a |
| branch, try: |
| <pre> |
| git config branch.master.remote origin |
| git config branch.master.merge master |
| </pre> |
| <p> |
| Otherwise, you have to say<code> git pull origin master </code> |
| each time you do a pull. |
| </p> |
| <li>Small changes to master |
| <p> |
| If you are an experienced git user working on substancial modifications, |
| you are probably |
| working on a separate branch and would rebase your branch prior to |
| merging with master. |
| But for small changes to the master branch itself, |
| you also need to use the rebase feature in order to avoid an |
| unnecessary and distracting branch in master. |
| </p> |
| <p> |
| If it has been awhile since you've done the initial clone, try |
| <pre> |
| git pull |
| </pre> |
| <p> |
| to get the latest files before you start working. |
| </p> |
| <p> |
| Make your changes and use |
| <pre> |
| git add <files to commit> |
| git commit |
| </pre> |
| <p> |
| to get your changes ready to push back into the fd.o repository. |
| </p> |
| <p> |
| It is possible (and likely) that someone has changed master since |
| you did your last pull. Even if your changes do not conflict with |
| their changes, git will make a fast-forward |
| merge branch, branching from the point in time |
| where you did your last pull and merging it to a point after the other changes. |
| </p> |
| <p> |
| To avoid this, |
| <pre> |
| git pull --rebase |
| git push |
| </pre> |
| <p> |
| If you are familiar with CVS or similar system, this is similar to doing a |
| <code> cvs update </code> in order to update your source tree to |
| the current repository state, instead of the time you did the last update. |
| (CVS doesn't work like git in this respect, but this is easiest way |
| to explain it.) |
| <br> |
| In any case, your repository now looks like you made your changes after |
| all the other changes. |
| </p> |
| <p> |
| If the rebase resulted in conflicts or changes that could affect |
| the proper operation of your changes, you'll need to investigate |
| those before doing the push. |
| </p> |
| <p> |
| If you want the rebase action to be the default action, then |
| <pre> |
| git config branch.master.rebase true |
| git config --global branch.autosetuprebase=always |
| </pre> |
| <p> |
| See <a href="http://www.eecs.harvard.edu/~cduan/technical/git/">Understanding Git Conceptually</a> for a fairly clear explanation about all of this. |

| <p> |
| This page describes the features and status of Mesa's support for the |
| <a href="http://opengl.org/documentation/glsl/"> |
| OpenGL Shading Language</a>. |
| </p> |

| </ul> |
| <h2 id="envvars">Environment Variables</h2> |
| <p> |
| The <b>MESA_GLSL</b> environment variable can be set to a comma-separated |
| list of keywords to control some aspects of the GLSL compiler and shader |
| execution. These are generally used for debugging. |
| </p> |
| <ul> |
| <li><b>dump</b> - print GLSL shader code to stdout at link time |
| <li><b>log</b> - log all GLSL shaders to files. |
| The filenames will be "shader_X.vert" or "shader_X.frag" where X |
| the shader ID. |
| <li><b>nopt</b> - disable compiler optimizations |
| <li><b>opt</b> - force compiler optimizations |
| <li><b>uniform</b> - print message to stdout when glUniform is called |
| <li><b>nopvert</b> - force vertex shaders to be a simple shader that just transforms |
| the vertex position with ftransform() and passes through the color and |
| texcoord[0] attributes. |
| <li><b>nopfrag</b> - force fragment shader to be a simple shader that passes |
| through the color attribute. |
| <li><b>useprog</b> - log glUseProgram calls to stderr |
| </ul> |
| <p> |
| Example: export MESA_GLSL=dump,nopt |
| </p> |
| <h2 id="support">GLSL Version</h2> |
| <p> |
| The GLSL compiler currently supports version 1.40 of the shading language. |
| </p> |
| <p> |
| Several GLSL extensions are also supported: |
| </p> |
| <ul> |
| <li>GL_ARB_draw_buffers |
| <li>GL_ARB_fragment_coord_conventions |
| <li>GL_ARB_shader_bit_encoding |
| </ul> |
| <h2 id="unsup">Unsupported Features</h2> |
| <p>XXX update this section</p> |
| <p> |
| The following features of the shading language are not yet fully supported |
| in Mesa: |
| </p> |
| <ul> |
| <li>Linking of multiple shaders does not always work. Currently, linking |
| is implemented through shader concatenation and re-compiling. This |
| doesn't always work because of some #pragma and preprocessor issues. |
| <li>The gl_Color and gl_SecondaryColor varying vars are interpolated |
| without perspective correction |
| </ul> |
| <p> |
| All other major features of the shading language should function. |
| </p> |
| <h2 id="notes">Implementation Notes</h2> |
| <ul> |
| <li>Shading language programs are compiled into low-level programs |
| very similar to those of GL_ARB_vertex/fragment_program. |
| <li>All vector types (vec2, vec3, vec4, bvec2, etc) currently occupy full |
| float[4] registers. |
| <li>Float constants and variables are packed so that up to four floats |
| can occupy one program parameter/register. |
| <li>All function calls are inlined. |
| <li>Shaders which use too many registers will not compile. |
| <li>The quality of generated code is pretty good, register usage is fair. |
| <li>Shader error detection and reporting of errors (InfoLog) is not |
| very good yet. |
| <li>The ftransform() function doesn't necessarily match the results of |
| fixed-function transformation. |
| </ul> |
| <p> |
| These issues will be addressed/resolved in the future. |
| </p> |
| <h2 id="hints">Programming Hints</h2> |
| <ul> |
| <li>Use the built-in library functions whenever possible. |
| For example, instead of writing this: |
| <pre> |
| float x = 1.0 / sqrt(y); |
| </pre> |
| Write this: |
| <pre> |
| float x = inversesqrt(y); |
| </pre> |
| </li> |
| </ul> |
| <h2 id="standalone">Stand-alone GLSL Compiler</h2> |
| <p> |
| The stand-alone GLSL compiler program can be used to compile GLSL shaders |
| into low-level GPU code. |
| </p> |
| <p> |
| This tool is useful for: |
| </p> |
| <ul> |
| <li>Inspecting GPU code to gain insight into compilation |
| <li>Generating initial GPU code for subsequent hand-tuning |
| <li>Debugging the GLSL compiler itself |
| </ul> |
| <p> |
| After building Mesa, the compiler can be found at src/glsl/glsl_compiler |
| </p> |
| <p> |
| Here's an example of using the compiler to compile a vertex shader and |
| emit GL_ARB_vertex_program-style instructions: |
| </p> |
| <pre> |
| src/glsl/glsl_compiler --dump-ast myshader.vert |
| </pre> |
| Options include |
| <ul> |
| <li><b>--dump-ast</b> - dump GPU code |
| <li><b>--dump-hir</b> - dump high-level IR code |
| <li><b>--dump-lir</b> - dump low-level IR code |
| <li><b>--link</b> - ??? |
| </ul> |
| <h2 id="implementation">Compiler Implementation</h2> |
| <p> |
| The source code for Mesa's shading language compiler is in the |
| <code>src/glsl/</code> directory. |
| </p> |
| <p> |
| XXX provide some info about the compiler.... |
| </p> |
| <p> |
| The final vertex and fragment programs may be interpreted in software |
| (see prog_execute.c) or translated into a specific hardware architecture |
| (see drivers/dri/i915/i915_fragprog.c for example). |
| </p> |
| <h3>Code Generation Options</h3> |
| <p> |
| Internally, there are several options that control the compiler's code |
| generation and instruction selection. |
| These options are seen in the gl_shader_state struct and may be set |
| by the device driver to indicate its preferences: |
| <pre> |
| struct gl_shader_state |
| { |
| ... |
| /** Driver-selectable options: */ |
| GLboolean EmitHighLevelInstructions; |
| GLboolean EmitCondCodes; |
| GLboolean EmitComments; |
| }; |
| </pre> |
| <dl> |
| <dt>EmitHighLevelInstructions</dt> |
| <dd> |
| This option controls instruction selection for loops and conditionals. |
| If the option is set high-level IF/ELSE/ENDIF, LOOP/ENDLOOP, CONT/BRK |
| instructions will be emitted. |
| Otherwise, those constructs will be implemented with BRA instructions. |
| </dd> |
| <dt>EmitCondCodes</dt> |
| <dd> |
| If set, condition codes (ala GL_NV_fragment_program) will be used for |
| branching and looping. |
| Otherwise, ordinary registers will be used (the IF instruction will |
| examine the first operand's X component and do the if-part if non-zero). |
| This option is only relevant if EmitHighLevelInstructions is set. |
| </dd> |
| <dt>EmitComments</dt> |
| <dd> |
| If set, instructions will be annoted with comments to help with debugging. |
| Extra NOP instructions will also be inserted. |
| </dd> |
| </dl> |
| <h2 id="validation">Compiler Validation</h2> |
| <p> |
| Developers working on the GLSL compiler should test frequently to avoid |
| regressions. |
| </p> |
| <p> |
| The <a href="http://piglit.freedesktop.org/">Piglit</a> project |
| has many GLSL tests. |
| </p> |
| <p> |
| The Mesa demos repository also has some good GLSL tests. |

| Additions to Chapter 3 the GLX 1.4 Specification (Functions and Errors) |
| Add a new section, 3.6 as follows: |
| 3.6 AGP Memory Access |
| On "PC" computers, AGP memory can be allocated with glXAllocateMemoryNV |
| and freed with glXFreeMemoryNV. Sometimes it's useful to know where a |
| block of AGP memory is located with respect to the start of the AGP |
| aperture. The function |
| GLuint glXGetAGPOffsetMESA( const GLvoid *pointer ) |
| Returns the offset of the given memory block from the start of AGP |
| memory in basic machine units (i.e. bytes). If pointer is invalid |
| the value ~0 will be returned. |
| GLX Protocol |
| None. This is a client side-only extension. |
| Errors |
| glXGetAGPOffsetMESA will return ~0 if the pointer does not point to |
| an AGP memory region. |

| Add to section 3.3.10 Double Buffering: |
| The function |
| void glXCopySubBufferMESA( Display *dpy, GLXDrawable drawable, |
| int x, int y, int width, int height ); |
| may be used to copy a rectangular region of the back color buffer to |
| the front color buffer. This can be used to quickly repaint 3D windows |
| in response to expose events when the back color buffer cannot be |
| damaged by other windows. |
| <x> and <y> indicates the lower-left corner of the region to copy and |
| <width> and <height> indicate the size in pixels. Coordinate (0,0) |
| corresponds to the lower-left pixel of the window, like glReadPixels. |
| If dpy and drawable are the display and drawable for the calling |
| thread's current context, glXCopySubBufferMESA performs an |
| implicit glFlush before it returns. Subsequent OpenGL commands |
| may be issued immediately after calling glXCopySubBufferMESA, but |
| are not executed until the copy is completed. |

| EGL Extension #not assigned |
| Dependencies |
| Requires EGL 1.4 or later. This extension is written against the |
| wording of the EGL 1.4 specification. |
| EGL_KHR_base_image is required. |
| Overview |
| This extension provides entry points for integrating EGLImage with the |
| Linux DRM mode setting and memory management drivers. The extension |
| lets applications create EGLImages without a client API resource and |
| lets the application get the DRM buffer handles. |
| IP Status |
| Open-source; freely implementable. |
| New Procedures and Functions |
| EGLImageKHR eglCreateDRMImageMESA(EGLDisplay dpy, |
| const EGLint *attrib_list); |
| EGLBoolean eglExportDRMImageMESA(EGLDisplay dpy, |
| EGLImageKHR image, |
| EGLint *name, |

| New Tokens |
| Accepted in the <attrib_list> parameter of eglCreateDRMImageMESA: |
| EGL_DRM_BUFFER_FORMAT_MESA 0x31D0 |
| EGL_DRM_BUFFER_USE_MESA 0x31D1 |
| Accepted as values for the EGL_IMAGE_FORMAT_MESA attribute: |
| EGL_DRM_BUFFER_FORMAT_ARGB32_MESA 0x31D2 |
| Bits accepted in EGL_DRM_BUFFER_USE_MESA: |
| EGL_DRM_BUFFER_USE_SCANOUT_MESA 0x0001 |
| EGL_DRM_BUFFER_USE_SHARE_MESA 0x0002 |
| EGL_DRM_BUFFER_USE_CURSOR_MESA 0x0004 |
| Accepted in the <target> parameter of eglCreateImageKHR: |
| EGL_DRM_BUFFER_MESA 0x31D3 |
| Use when importing drm buffer: |
| EGL_DRM_BUFFER_STRIDE_MESA 0x31D4 |
| EGL_DRM_BUFFER_FORMAT_MESA 0x31D0 |
| Additions to the EGL 1.4 Specification: |
| To create a DRM EGLImage, call |
| EGLImageKHR eglCreateDRMImageMESA(EGLDisplay dpy, |
| const EGLint *attrib_list); |
| In the attribute list, pass EGL_WIDTH, EGL_HEIGHT and format and |
| use in the attrib list using EGL_DRM_BUFFER_FORMAT_MESA and |
| EGL_DRM_BUFFER_USE_MESA. The only format specified by this |
| extension is EGL_DRM_BUFFER_FORMAT_ARGB32_MESA, where each pixel |
| is a CPU-endian, 32-bit quantity, with alpha in the upper 8 bits, |
| then red, then green, then blue. The bit values accepted by |
| EGL_DRM_BUFFER_USE_MESA are EGL_DRM_BUFFER_USE_SCANOUT_MESA, |
| EGL_DRM_BUFFER_USE_SHARE_MESA and EGL_DRM_BUFFER_USE_CURSOR_MESA. |
| EGL_DRM_BUFFER_USE_SCANOUT_MESA requests that the created EGLImage |
| should be usable as a scanout buffer with the DRM kernel |
| modesetting API. EGL_DRM_BUFFER_USE_SHARE_MESA requests that the |
| EGLImage can be shared with other processes by passing the |
| underlying DRM buffer name. EGL_DRM_BUFFER_USE_CURSOR_MESA |
| requests that the image must be usable as a cursor with KMS. When |
| EGL_DRM_BUFFER_USE_CURSOR_MESA is set, width and height must both |
| be 64. |
| To create a process local handle or a global DRM name for a |
| buffer, call |
| EGLBoolean eglExportDRMImageMESA(EGLDisplay dpy, |
| EGLImageKHR image, |
| EGLint *name, |
| EGLint *handle, |
| EGLint *stride); |
| If <name> is non-NULL, a global name is assigned to the image and |
| written to <name>, the handle (local to the DRM file descriptor, |
| for use with DRM kernel modesetting API) is written to <handle> if |
| non-NULL and the stride (in bytes) is written to <stride>, if |
| non-NULL. |
| Import a shared buffer by calling eglCreateImageKHR with |
| EGL_DRM_BUFFER_MESA as the target, using EGL_WIDTH, EGL_HEIGHT, |
| EGL_DRM_BUFFER_FORMAT_MESA, EGL_DRM_BUFFER_STRIDE_MESA |
| in the attrib list. |
| Issues |
| 1. Why don't we use eglCreateImageKHR with a target that |
| indicates that we want to create an EGLImage from scratch? |
| RESOLVED: The eglCreateImageKHR entry point is reserved for |
| creating an EGLImage from an already existing client API |
| resource. This is fine when we're creating the EGLImage from |
| an existing DRM buffer name, it doesn't seem right to overload |
| the function to also allocate the underlying resource. |
| 2. Why don't we use an eglQueryImageMESA type functions for |
| querying the DRM EGLImage attributes (name, handle, and stride)? |
| RESOLVED: The eglQueryImage function has been proposed often, |
| but it goes against the EGLImage design. EGLImages are opaque |
| handles to a 2D array of pixels, which can be passed between |
| client APIs. By referencing an EGLImage in a client API, the |
| EGLImage target (a texture, a renderbuffer or such) can be |
| used to query the attributes of the EGLImage. We don't have a |
| full client API for creating and querying DRM buffers, though, |
| so we use a new EGL extension entry point instead. |

| Overview |
| The GLX context setup encourages multithreaded applications to |
| create a context per thread which each operate on their own |
| objects in parallel, and leaves synchronization for write access |
| to shared objects up to the application. |
| For some applications, maintaining per-thread contexts and |
| ensuring that the glFlush happens in one thread before another |
| thread starts working on that object is difficult. For them, |
| using the same context across multiple threads and protecting its |
| usage with a mutex is both higher performance and easier to |
| implement. This extension gives those applications that option by |
| relaxing the context binding requirements. |
| This new behavior matches the requirements of AGL, while providing |
| a feature not specified in WGL. |
| IP Status |

| Changes to Chapter 2 of the GLX 1.3 Specification (Functions and Errors) |
| Replace the following sentence from section 2.2 Rendering Contexts: |
| In addition, a rendering context can be current for only one |
| thread at a time. |
| with: |
| In addition, an indirect rendering context can be current for |
| only one thread at a time. A direct rendering context may be |
| current to multiple threads, with synchronization of access to |
| the context thruogh the GL managed by the application through |
| mutexes. |
| Changes to Chapter 3 of the GLX 1.3 Specification (Functions and Errors) |
| Replace the following sentence from section 3.3.7 Rendering Contexts: |
| If ctx is current to some other thread, then |
| glXMakeContextCurrent will generate a BadAccess error. |
| with: |
| If ctx is an indirect context current to some other thread, |
| then glXMakeContextCurrent will generate a BadAccess error. |
| Replace the following sentence from section 3.5 Rendering Contexts: |
| If ctx is current to some other thread, then |
| glXMakeCurrent will generate a BadAccess error. |
| with: |
| If ctx is an indirect context current to some other thread, |
| then glXMakeCurrent will generate a BadAccess error. |
| GLX Protocol |
| None. The GLX extension only extends to direct rendering contexts. |
| Errors |
| None. |
| New State |
| None. |
| Issues |
| (1) What happens if the app binds a context/drawable in multiple |
| threads, then binds a different context/thread in one of them? |
| As with binding a new context from the current thread, the old |
| context's refcount is reduced and the new context's refcount is |
| increased. |
| (2) What happens if the app binds a context/drawable in multiple |
| threads, then binds None/None in one of them? |
| The GLX context is unreferenced from that thread, and the other |
| threads retain their GLX context binding. |
| (3) What happens if the app binds a context/drawable in 7 threads, |
| then destroys the context in one of them? |
| As with GLX context destruction previously, the XID is destroyed |
| but the context remains usable by threads that have the context |
| current. |
| (4) What happens if the app binds a new drawable/readable with |
| glXMakeCurrent() when it is already bound to another thread? |
| The context becomes bound to the new drawable/readable, and |
| further rendering in either thread will use the new |
| drawable/readable. |
| (5) What requirements should be placed on the user managing contexts |
| from multiple threads? |
| The intention is to allow multithreaded access to the GL at the |
| minimal performance cost, so requiring that the GL do general |
| synchronization (beyond that already required by context sharing) |
| is not an option, and synchronizing of GL's access to the GL |
| context between multiple threads is left to the application to do |
| across GL calls. However, it would be unfortunate for a library |
| doing multithread_makecurrent to require that other libraries |
| share in synchronization for binding of their own contexts, so the |
| refcounting of the contexts is required to be threadsafe. |
| (6) Does this apply to indirect contexts? |
| This was ignored in the initial revision of the spec. Behavior |
| for indirect contexts is left as-is. |

| This extensions is written against the OpenGL 1.4 Specification. |
| Overview |
| This extension adds a new pixel storage parameter to indicate that |
| images are to be packed in top-to-bottom order instead of OpenGL's |
| conventional bottom-to-top order. Only pixel packing can be |
| inverted (i.e. for glReadPixels, glGetTexImage, glGetConvolutionFilter, |
| etc). |
| Almost all known image file formats store images in top-to-bottom |
| order. As it is, OpenGL reads images from the frame buffer in |
| bottom-to-top order. Thus, images usually have to be inverted before |
| writing them to a file with image I/O libraries. This extension |
| allows images to be read such that inverting isn't needed. |
| IP Status |
| None |
| Issues |
| 1. Should we also define UNPACK_INVERT_MESA for glDrawPixels, etc? |
| Resolved: No, we're only concerned with pixel packing. There are other |
| solutions for inverting images when using glDrawPixels (negative Y pixel |
| zoom) or glTexImage (invert the vertex T coordinates). It would be easy |
| enough to define a complementary extension for pixel packing in the |
| future if needed. |

| Overview |
| Since Mesa allows RGB rendering into drawables with PseudoColor, |
| StaticColor, GrayScale and StaticGray visuals, Mesa needs a colormap |
| in order to compute pixel values during rendering. |
| The colormap associated with a window can be queried with normal |
| Xlib functions but there is no colormap associated with pixmaps. |
| The glXCreateGLXPixmapMESA function is an alternative to glXCreateGLXPixmap |
| which allows specification of a colormap. |

| Therefore, Mesa cannot immediately detect when an X window or pixmap is |

| Buffering)] |
| glXSwapIntervalMESA specifies the minimum number of video frame periods |
| per buffer swap. (e.g. a value of two means that the color buffers |
| will be swapped at most every other video frame.) A return value |
| of zero indicates success; otherwise an error occurred. The interval |
| takes effect when glXSwapBuffers is first called subsequent to the |
| glXSwapIntervalMESA call. |
| A video frame period is the time required by the monitor to display a |
| full frame of video data. In the case of an interlaced monitor, |
| this is typically the time required to display both the even and odd |
| fields of a frame of video data. |
| If <interval> is set to a value of 0, buffer swaps are not synchro- |
| nized to a video frame. The <interval> value is silently clamped to |
| the maximum implementation-dependent value supported before being |
| stored. |
| The swap interval is not part of the render context state. It cannot |
| be pushed or popped. The current swap interval for the window |
| associated with the current context can be obtained by calling |
| glXGetSwapIntervalMESA. The default swap interval is 0. |
| On XFree86, setting the environment variable LIBGL_THROTTLE_REFRESH sets |
| the swap interval to 1. |

| GLX_MESA_swap_control affects the definition of this extension. |
| GLX_OML_sync_control affects the definition of this extension. |
| Based on WGL_I3D_swap_frame_usage version 1.3. |
| Overview |
| This extension allows an application to determine what portion of the |
| swap period has elapsed since the last swap operation completed. The |
| "usage" value is a floating point value on the range [0,max] which is |
| calculated as follows: |
| td |
| percent = ---- |
| tf |
| where td is the time measured from the last completed buffer swap (or |
| call to enable the statistic) to when the next buffer swap completes, tf |
| is the entire time for a frame which may be multiple screen refreshes |
| depending on the swap interval as set by the GLX_SGI_swap_control or |
| GLX_OML_sync_control extensions. |
| The value, percent, indicates the amount of time spent between the |
| completion of the two swaps. If the value is in the range [0,1], the |
| buffer swap occurred within the time period required to maintain a |
| constant frame rate. If the value is in the range (1,max], a constant |
| frame rate was not achieved. The value indicates the number of frames |
| required to draw. |
| This definition of "percent" differs slightly from |
| WGL_I3D_swap_frame_usage. In WGL_I3D_swap_frame_usage, the measurement |
| is taken from the completion of one swap to the issuance of the next. |
| This representation may not be as useful as measuring between |
| completions, as a significant amount of time may pass between the |
| issuance of a swap and the swap actually occurring. |
| There is also a mechanism to determine whether a frame swap was |
| missed. |

| The frame usage is measured as the percentage of the swap period elapsed |
| between two buffer-swap operations being committed. In unextended GLX the |
| swap period is the vertical refresh time. If SGI_swap_control or |
| MESA_swap_control are supported, the swap period is the vertical refresh |
| time multiplied by the swap interval (or one if the swap interval is set |
| to zero). |
| If OML_sync_control is supported, the swap period is the vertical |
| refresh time multiplied by the divisor parameter to |
| glXSwapBuffersMscOML. The frame usage in this case is less than 1.0 if |
| the swap is committed before target_msc, and is greater than or equal to |
| 1.0 otherwise. The actual usage value is based on the divisor and is |
| never less than 0.0. |
| int glXBeginFrameTrackingMESA(Display *dpy, |
| GLXDrawable drawable, |
| float *usage) |
| glXGetFrameUsageMESA returns a floating-point value in <usage> |
| that represents the current swap usage, as defined above. |
| Missed frame swaps can be tracked by calling the following function: |
| int glXBeginFrameTrackingMESA(Display *dpy, |
| GLXDrawable drawable) |
| glXBeginFrameTrackingMESA resets a "missed frame" count and |
| synchronizes with the next frame vertical sync before it returns. |
| If a swap is missed based in the rate control specified by the |
| <interval> set by glXSwapIntervalSGI or the default swap of once |
| per frame, the missed frame count is incremented. |
| The current missed frame count and total number of swaps since |
| the last call to glXBeginFrameTrackingMESA can be obtained by |
| calling the following function: |
| int glXQueryFrameTrackingMESA(Display *dpy, |
| GLXDrawable drawable, |
| int64_t *swapCount, |
| int64_t *missedFrames, |
| float *lastMissedUsage) |
| The location pointed to by <swapCount> will be updated with the |
| number of swaps that have been committed. This value may not match the |
| number of swaps that have been requested since swaps may be |
| queued by the implementation. This function can be called at any |
| time and does not synchronize to vertical blank. |
| The location pointed to by <missedFrames> will contain the number |
| swaps that missed the specified frame. The frame usage for the |
| last missed frame is returned in the location pointed to by |
| <lastMissedUsage>. |
| Frame tracking is disabled by calling the function |
| int glXEndFrameTrackingMESA(Display *dpy, |
| GLXDrawable drawable) |
| This function will not return until all swaps have occurred. The |
| application can call glXQueryFrameTrackingMESA for a final swap and |
| missed frame count. |
| If these functions are successful, zero is returned. If the context |
| associated with dpy and drawable is not a direct context, |
| GLX_BAD_CONTEXT is returned. |
| Errors |
| If the function succeeds, zero is returned. If the function |
| fails, one of the following error codes is returned: |
| GLX_BAD_CONTEXT The current rendering context is not a direct |
| context. |

| OpenGL 1.2 or GL_EXT_texture3D is required. |
| Support for ARB_fragment_program is assumed, but not required. |
| Support for ARB_fragment_program_shadow is assumed, but not required. |
| Support for EXT_framebuffer_object is assumed, but not required. |
| Written based on the wording of the OpenGL 2.0 specification and |
| ARB_fragment_program_shadow but not dependent on them. |
| Overview |
| There are a number of circumstances where an application may wish to |
| blend two textures out of a larger set of textures. Moreover, in some |
| cases the selected textures may vary on a per-fragment basis within |
| a polygon. Several examples include: |
| 1. High dynamic range textures. The application stores several |
| different "exposures" of an image as different textures. On a |
| per-fragment basis, the application selects which exposures are |
| used. |
| 2. A terrain engine where the altitude of a point determines the |
| texture applied to it. If the transition is from beach sand to |
| grass to rocks to snow, the application will store each texture |
| in a different texture map, and dynamically select which two |
| textures to blend at run-time. |
| 3. Storing short video clips in textures. Each depth slice is a |
| single frame of video. |
| Several solutions to this problem have been proposed, but they either |
| involve using a separate texture unit for each texture map or using 3D |
| textures without mipmaps. Both of these options have major drawbacks. |
| This extension provides a third alternative that eliminates the major |
| drawbacks of both previous methods. A new texture target, |
| TEXTURE_2D_ARRAY, is added that functions identically to TEXTURE_3D in |
| all aspects except the sizes of the non-base level images. In |
| traditional 3D texturing, the size of the N+1 LOD is half the size |
| of the N LOD in all three dimensions. For the TEXTURE_2D_ARRAY target, |
| the height and width of the N+1 LOD is halved, but the depth is the |
| same for all levels of detail. The texture then becomes an array of |
| 2D textures. The per-fragment texel is selected by the R texture |
| coordinate. |

| Change the second and third paragraphs (page 179) to say (spec changes |
| identical to EXT_texture_array): |
| "In addition to image arrays for one-, two-, and three-dimensional |
| textures, one- and two-dimensional array textures, and the six image |
| arrays for the cube map texture, partially instantiated image arrays |
| are maintained for one-, two-, and three-dimensional textures and one- |
| and two-dimensional array textures. Additionally, a single proxy image |
| array is maintained for the cube map texture. Each proxy image array |
| includes width, height, depth, border width, and internal format state |
| values, as well as state for the red, green, blue, alpha, luminance, |
| and intensity component resolutions. Proxy image arrays do not include |
| image data, nor do they include texture properties. When TexImage3D is |
| executed with target specified as PROXY_TEXTURE_3D, the |
| three-dimensional proxy state values of the specified level-of-detail |
| are recomputed and updated. If the image array would not be supported |
| by TexImage3D called with target set to TEXTURE 3D, no error is |
| generated, but the proxy width, height, depth, border width, and |
| component resolutions are set to zero. If the image array would be |
| supported by such a call to TexImage3D, the proxy state values are set |
| exactly as though the actual image array were being specified. No pixel |
| data are transferred or processed in either case. |
| Proxy arrays for one- and two-dimensional textures and one- and |
| two-dimensional array textures are operated on in the same way when |
| TexImage1D is executed with target specified as PROXY_TEXTURE_1D, |
| TexImage2D is executed with target specified as PROXY_TEXTURE_2D or |
| PROXY_TEXTURE_1D_ARRAY_EXT, or TexImage3D is executed with target |
| specified as PROXY_TETXURE_2D_ARRAY_EXT." |
| -- Section 3.8.12 "Texture Objects" |
| Change section (page 180) to say (spec changes identical to |
| EXT_texture_array): |
| "In addition to the default textures TEXTURE_1D, TEXTURE_2D, |
| TEXTURE_3D, TEXTURE_CUBE_MAP, TEXTURE_1D_ARRAY_EXT, and TEXTURE_2D_EXT, |
| named one-, two-, and three-dimensional, cube map, and one- and |
| two-dimensional array texture objects can be created and operated upon. |
| The name space for texture objects is the unsigned integers, with zero |
| reserved by the GL. |
| A texture object is created by binding an unused name to TEXTURE_1D, |
| TEXTURE_2D, TEXTURE_3D, TEXTURE_CUBE_MAP, TEXTURE_1D_ARRAY_EXT, or |
| TEXTURE_2D_ARRAY_EXT. The binding is effected by calling |
| void BindTexture(enum target, uint texture); |
| with <target> set to the desired texture target and <texture> set to |
| the unused name. The resulting texture object is a new state vector, |
| comprising all the state values listed in section 3.8.11, set to the |
| same initial values. If the new texture object is bound to TEXTURE_1D, |
| TEXTURE_2D, TEXTURE_3D, TEXTURE_CUBE_MAP, TEXTURE_1D_ARRAY_EXT, or |
| TEXTURE_2D_ARRAY_EXT, it is and remains a one-, two-, |
| three-dimensional, cube map, one- or two-dimensional array texture |
| respectively until it is deleted. |
| BindTexture may also be used to bind an existing texture object to |
| either TEXTURE_1D, TEXTURE_2D, TEXTURE_3D, TEXTURE_CUBE_MAP, |
| TEXTURE_1D_ARRAY_EXT, or TEXTURE_2D_ARRAY_EXT. The error |
| INVALID_OPERATION is generated if an attempt is made to bind a texture |
| object of different dimensionality than the specified target. If the |
| bind is successful no change is made to the state of the bound texture |
| object, and any previous binding to target is broken. |
| While a texture object is bound, GL operations on the target to which |
| it is bound affect the bound object, and queries of the target to which |
| it is bound return state from the bound object. If texture mapping of |
| the dimensionality of the target to which a texture object is bound is |
| enabled, the state of the bound texture object directs the texturing |
| operation. |
| In the initial state, TEXTURE_1D, TEXTURE_2D, TEXTURE_3D, |
| TEXTURE_CUBE_MAP, TEXTURE_1D_ARRAY_EXT, and TEXTURE_2D_ARRAY_EXT have |
| one-, two-, three-dimensional, cube map, and one- and two-dimensional |
| array texture state vectors respectively associated with them. In order |
| that access to these initial textures not be lost, they are treated as |
| texture objects all of whose names are 0. The initial one-, two-, |
| three-dimensional, cube map, one- and two-dimensional array textures |
| are therefore operated upon, queried, and applied as TEXTURE_1D, |
| TEXTURE_2D, TEXTURE_3D, TEXTURE_CUBE_MAP, TEXTURE_1D_ARRAY_EXT, and |
| TEXTURE_2D_ARRAY_EXT respectively while 0 is bound to the corresponding |
| targets. |
| Change second paragraph on page 181 to say (spec changes identical to |
| EXT_texture_array): |
| "... If a texture that is currently bound to one of the targets |
| TEXTURE_1D, TEXTURE_2D, TEXTURE_3D, TEXTURE_CUBE_MAP, |
| TEXTURE_1D_ARRAY_EXT, or TEXTURE_2D_ARRAY_EXT is deleted, it is as |
| though BindTexture had been executed with the same target and texture |
| zero. ..." |
| Change second paragraph on page 182 to say (spec changes identical to |
| EXT_texture_array): |
| "The texture object name space, including the initial one-, two-, and |
| three dimensional, cube map, and one- and two-dimensional array texture |
| objects, is shared among all texture units. ..." |
| -- Section 3.8.14 "Depth Texture Comparison Modes" in "Texture Comparison Modes" |
| Change second through fourth paragraphs (page 188) to say: |
| "Let D_t be the depth texture value, in the range [0, 1]. For |
| texture lookups from one- and two-dimensional, rectangle, and |
| one-dimensional array targets, let R be the interpolated <r> |
| texture coordinate, clamped to the range [0, 1]. For texture lookups |
| from two-dimensional array texture targets, let R be the interpolated |
| <q> texture coordinate, clamped to the range [0, 1]. Then the |
| effective texture value L_t, I_t, or A_t is computed as follows: |
| If the value of TEXTURE_COMPARE_MODE is NONE, then |
| r = Dt |
| If the value of TEXTURE_COMPARE_MODE is |
| COMPARE_REF_DEPTH_TO_TEXTURE_EXT), then r depends on the texture |
| comparison function as shown in table 3.27." |
| -- Section 3.8.15 "Texture Application" |
| Change the first paragraph (page 189) to say: |
| "Texturing is enabled or disabled using the generic Enable and Disable |
| commands, respectively, with the symbolic constants TEXTURE_1D, |
| TEXTURE_2D, TEXTURE_3D, TEXTURE_CUBE_MAP, TEXTURE_1D_ARRAY_EXT, or |
| TEXTURE_2D_ARRAY_EXT to enable one-, two-, three-dimensional, cube |
| map, one-dimensional array, or two-dimensional array texture, |
| respectively. If both two- and one-dimensional textures are enabled, |
| the two-dimensional texture is used. If the three-dimensional and |
| either of the two- or one-dimensional textures is enabled, the |
| three-dimensional texture is used. If the cube map texture and any of |
| the three-, two-, or one-dimensional textures is enabled, then cube map |
| texturing is used. If one-dimensional array texture is enabled and any |
| of cube map, three-, two-, or one-dimensional textures is enabled, |
| one-dimensional array texturing is used. If two-dimensional array |
| texture is enabled and any of cube map, three-, two-, one-dimensional |
| textures or one-dimensional array texture is enabled, two-dimensional |
| array texturing is used..." |

| Issues |
| (1) Is "texture stack" a good name for this functionality? |
| NO. The name is changed to "array texture" to match the |
| nomenclature used by GL_EXT_texture_array. |
| (2) Should the R texture coordinate be treated as normalized or |
| un-normalized? If it were un-normalized, floor(R) could be thought |
| of as a direct index into the array texture. This may be more |
| convenient for applications. |
| RESOLVED. All texture coordinates are normalized. The issue of |
| un-normalized texture coordinates has been discussed in the ARB |
| before and should be left for a layered extension. |
| RE-RESOLVED. The R coordinate is un-normalized. Accessing an array |
| using [0, layers-1] coordinates is much more natural. |
| (3) How does LOD selection work for stacked textures? |
| RESOLVED. For 2D array textures the R coordinate is ignored, and |
| the LOD selection equations for 2D textures are used. For 1D |
| array textures the T coordinate is ignored, and the LOD selection |
| equations for 1D textures are used. The expected usage is in a |
| fragment program with an explicit LOD selection. |
| (4) What is the maximum size of a 2D array texture? Is it the same |
| as for a 3D texture, or should a new query be added? How about for 1D |
| array textures? |
| RESOLVED. A new query is added. |
| (5) How are array textures exposed in GLSL? |
| RESOLVED. Use GL_EXT_texture_array. |
| (6) Should a 1D array texture also be exposed? |
| RESOLVED. For orthogonality, yes. |
| (7) How are stacked textures attached to framebuffer objects? |
| RESOLVED. Layers of both one- and two-dimensional array textures |
| are attached using FreambufferTextureLayerEXT. Once attached, the |
| array texture layer behaves exactly as either a one- or |
| two-dimensional texture. |
| (8) How is this extension related to GL_EXT_texture_array? |
| This extension adapats GL_MESAX_texture_stack to the notation, |
| indexing, and FBO access of GL_EXT_texture_array. This extension |
| replaces the GLSL support of GL_EXT_texture_array with |
| GL_ARB_fragment_program support. |
| Assembly program support is also provided by GL_NV_gpu_program4. |
| GL_NV_gpu_program4 also adds support for other features that are |
| specific to Nvidia hardware, while this extension adds only support |
| for array textures. |
| Much of text of this extension that has changed since |
| GL_MESAX_texture_stack comes directly from either |
| GL_EXT_texture_array or GL_NV_gpu_program4. |

| Written based on the wording of the OpenGL 2.0 specification. |
| This extension trivially interacts with ARB_texture_float. |
| This extension shares some language with ARB_texture_compression_rgtc |
| but does not depend on it. |
| Overview |
| OpenGL prior to 3.1 does not support any signed texture formats. |
| ARB_texture_compression_rgtc introduces some compressed red and |
| red_green signed formats but no uncompressed ones, which might |
| still be useful. NV_texture_shader adds signed texture formats, |
| but also a lot of functionality which has been superseded by fragment |
| shaders. |
| It is usually possible to get the same functionality |
| using a unsigned format by doing scale and bias in a shader, but this |
| is undesirable since modern hardware has direct support for this. |
| This extension adds a signed 4-channel texture format by backporting |
| the relevant features from OpenGL 3.1, as a means to support this in |
| OpenGL implementations only supporting older versions. |
| Issues |
| 1) What should this extension be called? |
| RESOLVED: MESA_texture_signed_rgba seems reasonable. |
| The rgba part is there because only 4 channel format is supported. |
| 2) Should the full set of signed formats (alpha, luminance, rgb, etc.) |
| be supported? |
| RESOLVED: NO. To keep this extension simple, only add the most |
| universal format, rgba. alpha/luminance can't be trivially supported |
| since OpenGL 3.1 does not support them any longer, and there is some |
| implied dependency on ARB_texture_rg for red/red_green formats so |
| avoid all this. Likewise, only 8 bits per channel is supported. |
| 3) Should this extension use new enums for the texture formats? |
| RESOLVED: NO. Same enums as those used in OpenGL 3.1. |
| 4) How are signed integer values mapped to floating-point values? |
| RESOLVED: Same as described in issue 5) of |
| ARB_texture_compression_rgtc (quote): |
| A signed 8-bit two's complement value X is computed to |
| a floating-point value Xf with the formula: |
| { X / 127.0, X > -128 |
| Xf = { |
| { -1.0, X == -128 |
| This conversion means -1, 0, and +1 are all exactly representable, |
| however -128 and -127 both map to -1.0. Mapping -128 to -1.0 |
| avoids the numerical awkwardness of have a representable value |
| slightly more negative than -1.0. |
| This conversion is intentionally NOT the "byte" conversion listed |
| in Table 2.9 for component conversions. That conversion says: |
| Xf = (2*X + 1) / 255.0 |
| The Table 2.9 conversion is incapable of exactly representing |
| zero. |
| (Difference to ARB_texture_compression_rgtc): |
| This is the same mapping as OpenGL 3.1 uses. |
| This is also different to what NV_texture_shader used. |
| The above mapping should be considered the reference, but there |
| is some leeway so other mappings are allowed for implementations which |
| cannot do this. Particularly the mapping given in NV_texture_shader or |
| the standard OpenGL byte/float mapping is considered acceptable too, as |
| might be a mapping which represents -1.0 by -128, 0.0 by 0 and 1.0 by |
| 127 (that is, uses different scale factors for negative and positive |
| numbers). |
| Also, it is ok to store incoming GL_BYTE user data as-is, without |
| converting to GL_FLOAT (using the standard OpenGL float/byte mapping) |
| and converting back (using the mapping described here). |
| Other than those subtle issues there are no other non-standard |
| conversions used, so when using for instance CopyTexImage2D with |
| a framebuffer clamped to [0,1] all converted numbers will be in the range |
| [0, 127] (and not scaled and biased). |
| 5) How will signed components resulting from RGBA8_SNORM texture |
| fetches interact with fragment coloring? |
| RESOLVED: Same as described in issue 6) of |
| ARB_texture_compression_rgtc (quote): |
| The specification language for this extension is silent |
| about clamping behavior leaving this to the core specification |
| and other extensions. The clamping or lack of clamping is left |
| to the core specification and other extensions. |
| For assembly program extensions supporting texture fetches |
| (ARB_fragment_program, NV_fragment_program, NV_vertex_program3, |
| etc.) or the OpenGL Shading Language, these signed formats will |
| appear as expected with unclamped signed components as a result |
| of a texture fetch instruction. |
| If ARB_color_buffer_float is supported, its clamping controls |
| will apply. |
| NV_texture_shader extension, if supported, adds support for |
| fixed-point textures with signed components and relaxed the |
| fixed-function texture environment clamping appropriately. If the |
| NV_texture_shader extension is supported, its specified behavior |
| for the texture environment applies where intermediate values |
| are clamped to [-1,1] unless stated otherwise as in the case |
| of explicitly clamped to [0,1] for GL_COMBINE. or clamping the |
| linear interpolation weight to [0,1] for GL_DECAL and GL_BLEND. |
| Otherwise, the conventional core texture environment clamps |
| incoming, intermediate, and output color components to [0,1]. |
| This implies that the conventional texture environment |
| functionality of unextended OpenGL 1.5 or OpenGL 2.0 without |
| using GLSL (and with none of the extensions referred to above) |
| is unable to make proper use of the signed texture formats added |
| by this extension because the conventional texture environment |
| requires texture source colors to be clamped to [0,1]. Texture |
| filtering of these signed formats would be still signed, but |
| negative values generated post-filtering would be clamped to |
| zero by the core texture environment functionality. The |
| expectation is clearly that this extension would be co-implemented |
| with one of the previously referred to extensions or used with |
| GLSL for the new signed formats to be useful. |
| 6) Should the RGBA_SNORM tokens also be accepted by CopyTexImage |
| functions? |
| RESOLVED: YES. |
| 7) What to do with GetTexParameter if ARB_texture_float is supported, |
| in particular what datatype should this return for TEXTURE_RED_TYPE_ARB, |
| TEXTURE_GREEN_TYPE_ARB, TEXTURE_BLUE_TYPE_ARB, TEXTURE_ALPHA_TYPE_ARB? |
| RESOLVED: ARB_texture_float states type is either NONE, |
| UNSIGNED_NORMALIZED_ARB, or FLOAT. This extension adds a new enum, |
| SIGNED_NORMALIZED, which will be returned accordingly. This is the |

| OpenGL 1.0 is required. |
| The extension is written against the OpenGL 1.2 Specification |
| Overview |
| In order to set the current raster position to a specific window |
| coordinate with the RasterPos command, the modelview matrix, projection |
| matrix and viewport must be set very carefully. Furthermore, if the |
| desired window coordinate is outside of the window's bounds one must |
| rely on a subtle side-effect of the Bitmap command in order to circumvent |
| frustum clipping. |
| This extension provides a set of functions to directly set the |
| current raster position, bypassing the modelview matrix, the |
| projection matrix and the viewport to window mapping. Furthermore, |
| clip testing is not performed. |
| This greatly simplifies the process of setting the current raster |
| position to a specific window coordinate prior to calling DrawPixels, |
| CopyPixels or Bitmap. |

| This extension is written against the OpenGL 1.4 Specification. |
| NV_texture_rectangle effects the definition of this extension. |
| Overview |
| This extension supports texture images stored in the YCbCr format. |
| There is no support for converting YCbCr images to RGB or vice versa |
| during pixel transfer. The texture's YCbCr colors are converted to |
| RGB during texture sampling, after-which, all the usual per-fragment |
| operations take place. Only 2D texture images are supported (not |
| glDrawPixels, glReadPixels, etc). |
| A YCbCr pixel (texel) is a 16-bit unsigned short with two components. |
| The first component is luminance (Y). For pixels in even-numbered |
| image columns, the second component is Cb. For pixels in odd-numbered |
| image columns, the second component is Cr. If one were to convert the |
| data to RGB one would need to examine two pixels from columns N and N+1 |
| (where N is even) to deduce the RGB color. |

| Overview |
| Provides a mechanism for DrawPixels and ReadPixels to efficiently |
| transfer depth and stencil image data. Specifically, we defined new |
| packed pixel formats and types which pack both stencil and depth |
| into one value. |
| Issues: |
| 1. Is this the right way to distinguish between 24/8 and 8/24 |
| pixel formats? Should we instead provide both: |
| GL_DEPTH_STENCIL_MESA |
| GL_STENCIL_DEPTH_MESA |
| And perhaps just use GL_UNSIGNED_INT, GL_UNSIGNED_SHORT ? |
| 2. If not, is it correct to use _REV to indicate that stencil |
| preceeds depth in the 1_15 and 8_24 formats? |
| 3. Do we really want the GL_UNSIGNED_SHORT formats? |

| OpenGL 1.4 is required |
| The extension is written against the OpenGL 1.4 specification. |
| ARB_vertex_program or ARB_fragment_program or NV_vertex_program |
| or NV_fragment_program is required. |
| Overview |
| The extension provides facilities for implementing debuggers for |
| vertex and fragment programs. |
| The concept is that vertex and fragment program debuggers will be |
| implemented outside of the GL as a utility package. This extension |
| only provides the minimal hooks required to implement a debugger. |
| There are facilities to do the following: |
| 1. Have the GL call a user-specified function prior to executing |
| each vertex or fragment instruction. |
| 2. Query the current program string's execution position. |
| 3. Query the current values of intermediate program values. |
| The main feature is the ProgramCallbackMESA function. It allows the |
| user to register a callback function with the GL. The callback will |
| be called prior to executing each vertex or fragment program instruction. |
| From within the callback, the user may issue Get* commands to |
| query current GL state. The GetProgramRegisterfvMESA function allows |
| current program values to be queried (such as temporaries, input |
| attributes, and result registers). |
| There are flags for enabling/disabling the program callbacks. |
| The current execution position (as an offset from the start of the |
| program string) can be queried with |
| GetIntegerv(GL_FRAGMENT_PROGRAM_POSITION_MESA, &pos) or |
| GetIntegerv(GL_VERTEX_PROGRAM_POSITION_MESA, &pos). |
| IP Status |

| Issues |
| 1. Is this the right model for a debugger? |
| It seems prudent to minimize the scope of this extension and leave |
| it up to the developer (or developer community) to write debuggers |
| that layer on top of this extension. |
| If the debugger were fully implemented within the GL it's not |
| clear how terminal and GUI-based interfaces would work, for |
| example. |
| 2. There aren't any other extensions that register callbacks with |
| the GL. Isn't there another solution? |
| If we want to be able to single-step through vertex/fragment |
| programs I don't see another way to do it. |
| 3. How do we prevent the user from doing something crazy in the |
| callback function, like trying to call glBegin (leading to |
| recursion)? |
| The rule is that the callback function can only issue glGet*() |
| functions and no other GL commands. It could be difficult to |
| enforce this, however. Therefore, calling any non-get GL |
| command from within the callback will result in undefined |
| results. |
| 4. Is this extension amenable to hardware implementation? |
| Hopefully, but if not, the GL implementation will have to fall |
| back to a software path when debugging. This may be acceptable |
| for debugging. |
| 5. What's the <data> parameter to ProgramCallbackMESA for? |
| It's a common programming practice to associate a user-supplied |
| value with callback functions. |
| 6. Debuggers often allow one to modify intermediate program values, |
| then continue. Does this extension support that? |
| No. |

| In section 5.4 "Display Lists", page 202, add the following command |
| to the list of those that are not compiled into display lists: |
| ProgramCallbackMESA. |
| Add a new section 5.7 "Callback Functions" |
| The function |
| void ProgramCallbackMESA(enum target, programcallbackMESA callback, |
| void *data) |
| registers a user-defined callback function with the GL. <target> |
| may be FRAGMENT_PROGRAM_ARB or VERTEX_PROGRAM_ARB. The enabled |
| callback functions registered with these targets will be called |
| prior to executing each instruction in the current fragment or |
| vertex program, respectively. The callbacks are enabled and |
| disabled by calling Enable or Disable with <cap> |
| FRAGMENT_PROGRAM_ARB or VERTEX_PROGRAM_ARB. |
| The callback function's signature must match the typedef |
| typedef void (*programcallbackMESA)(enum target, void *data) |
| When the callback function is called, <target> will either be |
| FRAGMENT_PROGRAM_ARB or VERTEX_PROGRAM_ARB to indicate which |
| program is currently executing and <data> will be the value |
| specified when ProgramCallbackMESA was called. |
| From within the callback function, only the following GL commands |
| may be called: |
| GetBooleanv |
| GetDoublev |
| GetFloatv |
| GetIntegerv |
| GetProgramLocalParameter |
| GetProgramEnvParameter |
| GetProgramRegisterfvMESA |
| GetProgramivARB |
| GetProgramStringARB |
| GetError |

| Mesa 2.2 or later is required. |
| Overview |
| Mesa is often used as a client library with no integration with |
| the computer's window system (an X server, for example). And since |
| Mesa does not have an event loop nor window system callbacks, it |
| cannot properly respond to window system events. In particular, |
| Mesa cannot automatically detect when a window has been resized. |
| Mesa's glViewport command queries the current window size and updates |
| its internal data structors accordingly. This normally works fine |
| since most applications call glViewport in response to window size |
| changes. |
| In some situations, however, the application may not call glViewport |
| when a window size changes but would still like Mesa to adjust to |
| the new window size. This extension exports a new function to solve |
| this problem. |
| New Procedures and Functions |
| void glResizeBuffersMESA( void ) |
| New Tokens |

| Additions to the OpenGL Specification (no particular section) |
| The glResizeBuffersMESA command may be called when the client |
| determines that a window has been resized. Calling |
| glResizeBuffersMESA causes Mesa to query the current window size |
| and adjust its internal data structures. This may include |
| reallocating depth, stencil, alpha and accumulation buffers. |

| GL_EXT_point_parameters effects the definition of this extension |
| GL_ARB_multitexture effects the definition of this extension |
| Overview |
| This extension modifies the way in which points are rendered, |
| specifically when they're textured. When SPRITE_POINT_MESA is enabled |
| a point is rendered as if it were a quadrilateral with unique texture |
| coordinates at each vertex. This extension effectively turns points |
| into sprites which may be rendered more easily and quickly than using |
| conventional textured quadrilaterals. |
| When using point size > 1 or attenuated points this extension is an |
| effective way to render many small sprite images for particle systems |
| or other effects. |
| Issues: |
| 1. How are the texture coordinates computed? |
| The lower-left corner has texture coordinate (0,0,r,q). |
| The lower-right, (1,0,r,q). The upper-right, (1,1,r,q). |
| The upper-left, (0,1,r,q). |
| 2. What about texgen and texture matrices? |
| Texgen and the texture matrix have no effect on the point's s and t |
| texture coordinates. The r and q coordinates may have been computed |
| by texgen or the texture matrix. Note that with a 3D texture and/or |
| texgen that the r coordinate could be used to select a slice in the |
| 3D texture. |
| 3. What about point smoothing? |
| When point smoothing is enabled, a triangle fan could be rendered |
| to approximate a circular point. This could be problematic to |
| define and implement so POINT_SMOOTH is ignored when drawing sprite |
| points. |
| Smoothed points can be approximated by using an appropriate texture |
| images, alpha testing and blending. |
| POLYGON_SMOOTH does effect the rendering of the quadrilateral, however. |
| 4. What about sprite rotation? |
| There is none. Sprite points are always rendered as window-aligned |
| squares. One could define rotated texture images if desired. A 3D |
| texture and appropriate texture r coordinates could be used to |
| effectively specify image rotation per point. |
| 5. What about POLYGON_MODE? |
| POLYGON_MODE does not effect the rasterization of the quadrilateral. |
| 6. What about POLYGON_CULL? |
| TBD. Polygon culling is normally specified and implemented in the |
| transformation stage of OpenGL. However, some rasterization hardware |
| implements it later during triangle setup. |
| Polygon culling wouldn't be useful for sprite points since the |
| quadrilaterals are always defined in counter-clockwise order in |
| window space. For that reason, polygon culling should probably be |
| ignored. |
| 7. Should sprite points be alpha-attenuated if their size is below the |
| point parameter's threshold size? |
| 8. Should there be an advertisized maximum sprite point size? |
| No. Since we're rendering the point as a quadrilateral there's no |
| need to limit the size. |
| New Procedures and Functions |
| None. |
| New Tokens |
| Accepted by the <pname> parameter of Enable, Disable, IsEnabled, |

| Additions to Chapter 2 of the 1.1 Specification (OpenGL Operation) |
| None |
| Additions to Chapter 3 of the 1.1 Specification (Rasterization) |
| Section ???. |
| When SPRITE_POINT_MESA is enabled points are rasterized as screen- |
| aligned quadrilaterals. If the four vertices of the quadrilateral |
| are labeled A, B, C, and D, starting at the lower-left corner and moving |
| counter-clockwise around the quadrilateral, then the vertex and |
| texture coordinates are computed as follows: |
| vertex window coordinate texture coordinate |
| A (x-r, y-r, z, w) (0, 0, r, q) |
| B (x+r, y-r, z, w) (1, 0, r, q) |
| C (x+r, y+r, z, w) (1, 1, r, q) |
| D (x-r, y+r, z, w) (0, 1, r, q) |
| where x, y, z, w are the point's window coordinates, r and q are the |
| point's 3rd and 4th texture coordinates and r is half the point's |
| size. The other vertex attributes (such as the color and fog coordinate) |
| are simply duplicated from the original point vertex. |
| Point size may either be specified with PointSize or computed |
| according to the EXT_point_parameters extension. |
| The new texture coordinates are not effected by texgen or the texture |
| matrix. Note, however, that the texture r and q coordinates are passed |
| unchanged and may have been computed with texgen and/or the texture |
| matrix. |
| If multiple texture units are present the same texture coordinate is |
| used for all texture units. |
| The point is then rendered as if it were a quadrilateral using the |
| normal point sampling rules. POLYGON_MODE does not effect the |
| rasterization of the quadrilateral but POLYGON_SMOOTH does. |
| POINT_SMOOTH has no effect when SPRITE_POINT_MESA is enabled. |

| OpenGL 1.2 is required. |
| The extension is written against the OpenGL 1.2 Specification |
| Overview |
| Provides the application with means to enable and disable logging |
| of GL calls including parameters as readable text. The verbosity |
| of the generated log can be controlled. The resulting logs are |
| valid (but possibly incomplete) C code and can be compiled and |
| linked for standalone test programs. The set of calls and the |
| amount of static data that is logged can be controlled at runtime. |
| The application can add comments and enable or disable tracing of GL |
| operations at any time. The data flow from the application to GL |
| and back is unaffected except for timing. |
| Application-side implementation of these features raises namespace |
| and linkage issues. In the driver dispatch table a simple |
| "chain of responsibility" pattern (aka "composable piepline") |
| can be added. |
| IP Status |
| The extension spec is in the public domain. The current implementation |
| in Mesa is covered by Mesa's XFree86-style copyright by the authors above. |
| This extension is partially inspired by the Quake2 QGL wrapper. |
| Issues |
| (1) Is this Extension obsolete because it can |
| be implemented as a wrapper DLL? |
| RESOLVED: No. While certain operating systems (Win32) provide linkers |
| that facilitate this kind of solution, other operating systems |
| (Linux) do not support hierarchical linking, so a wrapper solution |
| would result in symbol collisions. |
| Further, IHV's might have builtin support for tracing GL execution |
| that enjoys privileged access, or that they do not wish to separate |
| the tracing code from their driver code base. |
| (2) Should the Trace API explicitely support the notion of "frames? |
| This would require hooking into glXSwapBuffers calls as well. |
| RESOLVED: No. The application can use NewTraceMESA/EndTraceMESA |
| and TraceComment along with external parsing tools to split the |
| trace into frames, in whatever way considered adequate. |
| (2a) Should GLX calls be traced? |
| PBuffers and other render-to-texture solutions demonstrate that |
| context level commands beyond SwapBuffers might have to be |
| traced. The GL DLL exports the entry points, so this would not |
| be out of the question. |
| (3) Should the specification mandate the actual output format? |
| RESOLVED: No. It is sufficient to guarantee that all data and commands |
| will be traced as requested by Enable/DisableTraceMESA, in the order |
| encountered. Whether the resulting trace is available as a readable |
| text file, binary metafile, compilable source code, much less which |
| indentation and formatting has been used, is up to the implementation. |
| For the same reason this specification does not enforce or prohibit |
| additional information added to the trace (statistics, profiling/timing, |
| warnings on possible error conditions). |
| (4) Should the comment strings associated with names and pointer (ranges) |
| be considered persistent state? |
| RESOLVED: No. The implementation is not forced to use this information |
| on subsequent occurences of name/pointer, and is free to consider it |
| transient state. |
| (5) Should comment commands be prohibited between Begin/End? |
| RESOLVED: Yes, with the exception of TraceCommentMESA. TraceCommentMESA |
| is transient, the other commands might cause storage of persistent |
| data in the context. There is no need to have the ability mark names |
| or pointers between Begin and End. |

| 5.7 Tracing |
| The tracing facility is used to record the execution of a GL program |
| to a human-readable log. The log appears as a sequence of GL commands |
| using C syntax. The primary intention of tracing is to aid in program |
| debugging. |
| A trace is started with the command |
| void NewTraceMESA( bitfield mask, const GLubyte * traceName ) |
| <mask> may be any value accepted by PushAttrib and specifies a set of |
| attribute groups. The state values included in those attribute groups |
| is written to the trace as a sequence of GL commands. |
| <traceName> specifies a name or label for the trace. It is expected |
| that <traceName> will be interpreted as a filename in most implementations. |
| A trace is ended by calling the command |
| void EndTraceMESA( void ) |
| It is illegal to call NewTraceMESA or EndTraceMESA between Begin and End. |
| The commands |
| void EnableTraceMESA( bitfield mask ) |
| void DisableTraceMESA( bitfield mask ) |
| enable or disable tracing of different classes of GL commands. |
| <mask> may be the union of any of TRACE_OPERATIONS_BIT_MESA, |
| TRACE_PRIMITIVES_BIT_MESA, TRACE_ARRAYS_BIT_MESA, TRACE_TEXTURES_BIT_MESA, |
| and TRACE_PIXELS_BIT_MESA. The special token TRACE_ALL_BITS_MESA |
| indicates all classes of commands are to be logged. |
| TRACE_OPERATIONS_BIT_MESA controls logging of all commands outside of |
| Begin/End, including Begin/End. |
| TRACE_PRIMITIVES_BIT_MESA controls logging of all commands inside of |
| Begin/End, including Begin/End. |
| TRACE_ARRAYS_BIT_MESA controls logging of VertexPointer, NormalPointer, |
| ColorPointer, IndexPointer, TexCoordPointer and EdgeFlagPointer commands. |
| TRACE_TEXTURES_BIT_MESA controls logging of texture data dereferenced by |
| TexImage1D, TexImage2D, TexImage3D, TexSubImage1D, TexSubImage2D, and |
| TexSubImage3D commands. |
| TRACE_PIXELS_BIT_MESA controls logging of image data dereferenced by |
| Bitmap and DrawPixels commands. |
| TRACE_ERRORS_BIT_MESA controls logging of all errors. If this bit is |
| set, GetError will be executed whereever applicable, and the result will |
| be added to the trace as a comment. The error returns are cached and |
| returned to the application on its GetError calls. If the user does not |
| wish the additional GetError calls to be performed, this bit should not |
| be set. |
| The command |
| void TraceCommentMESA( const ubyte* comment ) |
| immediately adds the <comment> string to the trace output, surrounded |
| by C-style comment delimiters. |
| The commands |
| void TraceTextureMESA( uint name, const ubyte* comment ) |
| void TraceListMESA( uint name, const ubyte* comment ) |
| associates <comment> with the texture object or display list specified |
| by <name>. Logged commands which reference the named texture object or |
| display list will be annotated with <comment>. If IsTexture(name) or |
| IsList(name) fail (respectively) the command is quietly ignored. |
| The commands |
| void TracePointerMESA( void* pointer, const ubyte* comment ) |
| void TracePointerRangeMESA( const void* first, |
| const void* last, |
| const ubyte* comment ) |
| associate <comment> with the address specified by <pointer> or with |
| a range of addresses specified by <first> through <last>. |
| Any logged commands which reference <pointer> or an address between |
| <first> and <last> will be annotated with <comment>. |
| The command |
| void TraceAssertAttribMESA( bitfield attribMask ) |
| will add GL state queries and assertion statements to the log to |
| confirm that the current state at the time TraceAssertAttrib is |
| executed matches the current state when the trace log is executed |
| in the future. |
| <attribMask> is any value accepted by PushAttrib and specifies |
| the groups of state variables which are to be asserted. |
| The commands NewTraceMESA, EndTraceMESA, EnableTraceMESA, DisableTraceMESA, |
| TraceAssertAttribMESA, TraceCommentMESA, TraceTextureMESA, TraceListMESA, |
| TracePointerMESA and TracePointerRangeMESA are not compiled into display lists. |
| Examples: |
| The command NewTraceMESA(DEPTH_BUFFER_BIT, "log") will query the state |
| variables DEPTH_TEST, DEPTH_FUNC, DEPTH_WRITEMASK, and DEPTH_CLEAR_VALUE |
| to get the values <test>, <func>, <mask>, and <clear> respectively. |
| Statements equivalent to the following will then be logged: |
| glEnable(GL_DEPTH_TEST); (if <test> is true) |
| glDisable(GL_DEPTH_TEST); (if <test> is false) |
| glDepthFunc(<func>); |
| glDepthMask(<mask>); |
| glClearDepth(<clear>); |
| The command TraceAssertAttribMESA(DEPTH_BUFFER_BIT) will query the state |
| variables DEPTH_TEST, DEPTH_FUNC, DEPTH_WRITEMASK, and DEPTH_CLEAR_VALUE |
| to get the values <test>, <func>, <mask>, and <clear> respectively. |
| The resulting trace might then look will like this: |
| { |
| GLboolean b; |
| GLint i; |
| GLfloat f; |
| b = glIsEnabled(GL_DEPTH_TEST); |
| assert(b == <test>); |
| glGetIntegerv(GL_DEPTH_FUNC, &i); |
| assert(i == <func>); |
| glGetIntegerv(GL_DEPTH_MASK, &i); |
| assert(i == <mask>); |
| glGetFloatv(GL_DEPTH_CLEAR_VALUE, &f); |
| assert(f == <clear>); |
| } |
| Additions to Chapter 6 of the OpenGL 1.2.1 Specification |
| (State and State Requests) |
| Querying TRACE_MASK_MESA with GetIntegerv, GetFloatv, GetBooleanv or |
| GetDoublev returns the current command class trace mask. |
| Querying TRACE_NAME_MESA with GetString returns the current trace name. |
| Additions to Appendix A of the OpenGL 1.2.1 Specification (Invariance) |
| The MESA_trace extension can be used in a way that does not affect data |
| flow from application to OpenGL, as well as data flow from OpenGL to |
| application, except for timing, possible print I/O. TRACE_ERRORS_BIT_MESA |
| will add additional GetError queries. Setting a trace mask with NewTraceMESA |
| as well as use of TraceAssertAttribMESA might cause additional state queries. |
| With the possible exception of performance, OpenGL rendering should not be |
| affected at all by a properly chosen logging operation. |
| Additions to the AGL/GLX/WGL Specifications |
| None. |
| GLX Protocol |
| None. The logging operation is carried out client-side, by exporting |
| entry points to the wrapper functions that execute the logging operation. |
| Errors |
| INVALID_OPERATION is generated if any trace command except TraceCommentMESA |
| is called between Begin and End. |
| New State |
| The current trace name and current command class mask are stored |
| per-context. |
| New Implementation Dependent State |
| None. |

| EGL Extension #not assigned |
| Dependencies |
| Requires EGL 1.4 or later. This extension is written against the |
| wording of the EGL 1.4 specification. |
| EGL_KHR_base_image is required. |
| Overview |
| This extension provides entry points for binding and unbinding the |
| wl_display of a Wayland compositor to an EGLDisplay. Binding a |
| wl_display means that the EGL implementation should provide one or |
| more interfaces in the Wayland protocol to allow clients to create |
| wl_buffer objects. On the server side, this extension also |
| provides a new target for eglCreateImageKHR, to create an EGLImage |
| from a wl_buffer |
| Adding an implementation specific wayland interface, allows the |
| EGL implementation to define specific wayland requests and events, |
| needed for buffer sharing in an EGL wayland platform. |
| IP Status |
| Open-source; freely implementable. |
| New Procedures and Functions |

| EGL_TEXTURE_Y_UV_WL 0x31D8 |
| EGL_TEXTURE_Y_XUXV_WL 0x31D9 |
| Additions to the EGL 1.4 Specification: |
| To bind a server side wl_display to an EGLDisplay, call |
| EGLBoolean eglBindWaylandDisplayWL(EGLDisplay dpy, |
| struct wl_display *display); |
| To unbind a server side wl_display from an EGLDisplay, call |
| EGLBoolean eglUnbindWaylandDisplayWL(EGLDisplay dpy, |
| struct wl_display *display); |
| eglBindWaylandDisplayWL returns EGL_FALSE when there is already a |
| wl_display bound to EGLDisplay otherwise EGL_TRUE. |
| eglUnbindWaylandDisplayWL returns EGL_FALSE when there is no |
| wl_display bound to the EGLDisplay currently otherwise EGL_TRUE. |
| A wl_buffer can have several planes, typically in case of planar |
| YUV formats. Depending on the exact YUV format in use, the |
| compositor will have to create one or more EGLImages for the |
| various planes. The eglQueryWaylandBufferWL function should be |
| used to first query the wl_buffer texture format using |
| EGL_TEXTURE_FORMAT as the attribute. If the wl_buffer object is |
| not an EGL wl_buffer (wl_shm and other wayland extensions can |
| create wl_buffer objects of different types), this query will |
| return EGL_FALSE. In that case the wl_buffer can not be used with |
| EGL and the compositor should have another way to get the buffer |
| contents. |
| If eglQueryWaylandBufferWL succeeds, the returned value will be |
| one of EGL_TEXTURE_RGB, EGL_TEXTURE_RGBA, EGL_TEXTURE_Y_U_V_WL, |
| EGL_TEXTURE_Y_UV_WL, EGL_TEXTURE_Y_XUXV_WL. The value returned |
| describes how many EGLImages must be used, which components will |
| be sampled from each EGLImage and how they map to rgba components |
| in the shader. The naming conventions separates planes by _ and |
| within each plane, the order or R, G, B, A, Y, U, and V indicates |
| how those components map to the rgba value returned by the |
| sampler. X indicates that the corresponding component in the rgba |
| value isn't used. |
| RGB and RGBA buffer types: |
| EGL_TEXTURE_RGB |
| One plane, samples RGB from the texture to rgb in the |
| shader. Alpha channel is not valid. |
| EGL_TEXTURE_RGBA |
| One plane, samples RGBA from the texture to rgba in the |
| shader. |
| YUV buffer types: |
| EGL_TEXTURE_Y_U_V_WL |
| Three planes, samples Y from the first plane to r in |
| the shader, U from the second plane to r, and V from |
| the third plane to r. |
| EGL_TEXTURE_Y_UV_WL |
| Two planes, samples Y from the first plane to r in |
| the shader, U and V from the second plane to rg. |
| EGL_TEXTURE_Y_XUXV_WL |
| Two planes, samples Y from the first plane to r in |
| the shader, U and V from the second plane to g and a. |
| After querying the wl_buffer layout, create EGLImages for the |
| planes by calling eglCreateImageKHR with wl_buffer as |
| EGLClientBuffer, EGL_WAYLAND_BUFFER_WL as the target, NULL |
| context. If no attributes are given, an EGLImage will be created |
| for the first plane. For multi-planar buffers, specify the plane |
| to create the EGLImage for by using the EGL_WAYLAND_PLANE_WL |
| attribute. The value of the attribute is the index of the plane, |
| as defined by the buffer format. Writing to an EGLImage created |
| from a wl_buffer in any way (such as glTexImage2D, binding the |
| EGLImage as a renderbuffer etc) will result in undefined behavior. |
| Further, eglQueryWaylandBufferWL accepts attributes EGL_WIDTH and |
| EGL_HEIGHT to query the width and height of the wl_buffer. |

| <h1>Supported Systems and Drivers</h1> |
| <p> |
| Mesa is primarily developed and used on Linux systems. |
| But there's also support for Windows, other flavors of Unix and other |
| systems such as Haiku. |
| We're actively developing and maintaining several hardware and |
| software drivers. |
| </p> |
| <p> |
| The primary API is OpenGL but there's also support for OpenGL ES 1, ES2 |
| and ES 3, OpenVG, OpenCL, VDPAU, XvMC and the EGL interface. |
| </p> |
| <p> |
| Hardware drivers include: |
| </p> |
| <ul> |
| <li>Intel i965, i945, i915. |
| See <a href="http://intellinuxgraphics.org/index.html"> |
| Intel's website</a></li> |
| <li>AMD Radeon series. |
| See <a href="http://www.x.org/wiki/RadeonFeature">RadeonFeature</a></li> |
| <li>NVIDIA GPUs. |
| See <a href="http://nouveau.freedesktop.org">Nouveau Wiki</a></li> |
| <li><a href="http://www.x.org/wiki/vmware">VMware virtual GPU</a></li> |
| </ul> |
| <p> |
| Software drivers include: |

| <h1> |
| Deprecated Systems and Drivers |
| </h1> |
| <p> |
| In the past there were other drivers for older GPUs and operating |
| systems. |
| These have been removed from the Mesa source tree and distribution. |
| If anyone's interested though, the code can be found in the git repo. |
| The list includes: |

| <h1>Viewperf Issues</h1> |
| <p> |
| This page lists known issues with |
| <a href="http://www.spec.org/gwpg/gpc.static/vp11info.html" target="_main">SPEC Viewperf 11</a> |
| when running on Mesa-based drivers. |
| </p> |
| <p> |
| The Viewperf data sets are basically GL API traces that are recorded from |
| CAD applications, then replayed in the Viewperf framework. |
| </p> |
| <p> |
| The primary problem with these traces is they blindly use features and |
| OpenGL extensions that were supported by the OpenGL driver when the trace |
| was recorded, |
| but there's no checks to see if those features are supported by the driver |
| when playing back the traces with Viewperf. |
| </p> |
| <p> |
| These issues have been reported to the SPEC organization in the hope that |
| they'll be fixed in the future. |
| </p> |
| <p> |
| Some of the Viewperf tests use a lot of memory. |
| At least 2GB of RAM is recommended. |
| </p> |
| <h2>Catia-03 test 2</h2> |
| <p> |
| This test creates over 38000 vertex buffer objects. On some systems |
| this can exceed the maximum number of buffer allocations. Mesa |
| generates GL_OUT_OF_MEMORY errors in this situation, but Viewperf |
| does no error checking and continues. When this happens, some drawing |
| commands become no-ops. This can also eventually lead to a segfault |
| either in Viewperf or the Mesa driver. |
| </p> |
| <h2>Catia-03 tests 3, 4, 8</h2> |
| <p> |
| These tests use features of the |
| <a href="http://www.opengl.org/registry/specs/NV/fragment_program2.txt" |
| target="_main"> |
| GL_NV_fragment_program2</a> and |
| <a href="http://www.opengl.org/registry/specs/NV/vertex_program3.txt" |
| target="_main"> |
| GL_NV_vertex_program3</a> extensions without checking if the driver supports |
| them. |
| </p> |
| <p> |
| When Mesa tries to compile the vertex/fragment programs it generates errors |
| (which Viewperf ignores). |
| Subsequent drawing calls become no-ops and the rendering is incorrect. |
| </p> |
| <h2>sw-02 tests 1, 2, 4, 6</h2> |
| <p> |
| These tests depend on the |
| <a href="http://www.opengl.org/registry/specs/NV/primitive_restart.txt" |
| target="_main">GL_NV_primitive_restart</a> extension. |
| </p> |
| <p> |
| If the Mesa driver doesn't support this extension the rendering will |
| be incorrect and the test will fail. |
| </p> |
| <p> |
| Also, the color of the line drawings in test 2 seem to appear in a random |
| color. This is probably due to some uninitialized state somewhere. |
| </p> |
| <h2>sw-02 test 6</h2> |
| <p> |
| The lines drawn in this test appear in a random color. |
| That's because texture mapping is enabled when the lines are drawn, but no |
| texture image is defined (glTexImage2D() is called with pixels=NULL). |
| Since GL says the contents of the texture image are undefined in that |
| situation, we get a random color. |
| </p> |
| <h2>Lightwave-01 test 3</h2> |
| <p> |
| This test uses a number of mipmapped textures, but the textures are |
| incomplete because the last/smallest mipmap level (1 x 1 pixel) is |
| never specified. |
| </p> |
| <p> |
| A trace captured with |
| <a href="https://github.com/apitrace/apitrace" target="_main">API trace</a> |
| shows this sequences of calls like this: |
| <pre> |
| 2504 glBindTexture(target = GL_TEXTURE_2D, texture = 55) |
| 2505 glTexImage2D(target = GL_TEXTURE_2D, level = 0, internalformat = GL_RGBA, width = 512, height = 512, border = 0, format = GL_RGB, type = GL_UNSIGNED_SHORT, pixels = blob(1572864)) |
| 2506 glTexImage2D(target = GL_TEXTURE_2D, level = 1, internalformat = GL_RGBA, width = 256, height = 256, border = 0, format = GL_RGB, type = GL_UNSIGNED_SHORT, pixels = blob(393216)) |
| 2507 glTexImage2D(target = GL_TEXTURE_2D, level = 2, internalformat = GL_RGBA, width = 128, height = 128, border = 0, format = GL_RGB, type = GL_UNSIGNED_SHORT, pixels = blob(98304)) |
| [...] |
| 2512 glTexImage2D(target = GL_TEXTURE_2D, level = 7, internalformat = GL_RGBA, width = 4, height = 4, border = 0, format = GL_RGB, type = GL_UNSIGNED_SHORT, pixels = blob(96)) |
| 2513 glTexImage2D(target = GL_TEXTURE_2D, level = 8, internalformat = GL_RGBA, width = 2, height = 2, border = 0, format = GL_RGB, type = GL_UNSIGNED_SHORT, pixels = blob(24)) |
| 2514 glTexParameteri(target = GL_TEXTURE_2D, pname = GL_TEXTURE_MIN_FILTER, param = GL_LINEAR_MIPMAP_LINEAR) |
| 2515 glTexParameteri(target = GL_TEXTURE_2D, pname = GL_TEXTURE_WRAP_S, param = GL_REPEAT) |
| 2516 glTexParameteri(target = GL_TEXTURE_2D, pname = GL_TEXTURE_WRAP_T, param = GL_REPEAT) |
| 2517 glTexParameteri(target = GL_TEXTURE_2D, pname = GL_TEXTURE_MAG_FILTER, param = GL_NEAREST) |
| </pre> |
| <p> |
| Note that one would expect call 2514 to be glTexImage(level=9, width=1, |
| height=1) but it's not there. |
| </p> |
| <p> |
| The minification filter is GL_LINEAR_MIPMAP_LINEAR and the texture's |
| GL_TEXTURE_MAX_LEVEL is 1000 (the default) so a full mipmap is expected. |
| </p> |
| <p> |
| Later, these incomplete textures are bound before drawing calls. |
| According to the GL specification, if a fragment program or fragment shader |
| is being used, the sampler should return (0,0,0,1) ("black") when sampling |
| from an incomplete texture. |
| This is what Mesa does and the resulting rendering is darker than it should |
| be. |
| </p> |
| <p> |
| It appears that NVIDIA's driver (and possibly AMD's driver) detects this case |
| and returns (1,1,1,1) (white) which causes the rendering to appear brighter |
| and match the reference image (however, AMD's rendering is <em>much</em> |
| brighter than NVIDIA's). |
| </p> |
| <p> |
| If the fallback texture created in _mesa_get_fallback_texture() is |
| initialized to be full white instead of full black the rendering appears |
| correct. |
| However, we have no plans to implement this work-around in Mesa. |
| </p> |
| <h2>Maya-03 test 2</h2> |
| <p> |
| This test makes some unusual calls to glRotate. For example: |
| </p> |
| <pre> |
| glRotate(50, 50, 50, 1); |
| glRotate(100, 100, 100, 1); |
| glRotate(52, 52, 52, 1); |
| </pre> |
| <p> |
| These unusual values lead to invalid modelview matrices. |
| For example, the last glRotate command above produces this matrix with Mesa: |
| <pre> |
| 1.08536e+24 2.55321e-23 -0.000160389 0 |
| 5.96937e-25 1.08536e+24 103408 0 |
| 103408 -0.000160389 1.74755e+09 0 |
| 0 0 0 nan |
| </pre> |
| and with NVIDIA's OpenGL: |
| <pre> |
| 1.4013e-45 0 -nan 0 |
| 0 1.4013e-45 1.4013e-45 0 |
| 1.4013e-45 -nan 1.4013e-45 0 |
| 0 0 0 1.4013e-45 |
| </pre> |
| <p> |
| This causes the object in question to be drawn in a strange orientation |
| and with a semi-random color (between white and black) since GL_FOG is enabled. |
| </p> |
| <h2>Proe-05 test 1</h2> |
| <p> |
| This uses depth testing but there's two problems: |
| <ol> |
| <li>The glXChooseFBConfig() call doesn't request a depth buffer |
| <li>The test never calls glClear(GL_DEPTH_BUFFER_BIT) to initialize the depth buffer |
| </ol> |
| <p> |
| If the chosen visual does not have a depth buffer, you'll see the wireframe |
| car model but it won't be rendered correctly. |
| </p> |
| If (by luck) the chosen visual has a depth buffer, its initial contents |
| will be undefined so you may or may not see parts of the model. |
| <p> |
| Interestingly, with NVIDIA's driver most visuals happen to have a depth buffer |
| and apparently the contents are initialized to 1.0 by default so this test |
| just happens to work with their drivers. |
| </p> |
| <p> |
| Finally, even if a depth buffer was requested and the glClear(GL_COLOR_BUFFER_BIT) |
| calls were changed to glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT) |
| the problem still wouldn't be fixed because GL_DEPTH_WRITEMASK=GL_FALSE when |
| glClear is called so clearing the depth buffer would be a no-op anyway. |
| </p> |
| <h2>Proe-05 test 6</h2> |
| <p> |
| This test draws an engine model with a two-pass algorithm. |
| The first pass is drawn with polygon stipple enabled. |
| The second pass is drawn without polygon stipple but with blending |
| and GL_DEPTH_FUNC=GL_LEQUAL. |
| If either of the two passes happen to use a software fallback of some |
| sort, the Z values of fragments may be different between the two passes. |
| This leads to incorrect rendering. |
| </p> |
| <p> |
| For example, the VMware SVGA gallium driver uses a special semi-fallback path |
| for drawing with polygon stipple. |
| Since the two passes are rendered with different vertex transformation |
| implementations, the rendering doesn't appear as expected. |
| Setting the SVGA_FORCE_SWTNL environment variable to 1 will force the |
| driver to use the software vertex path all the time and clears up this issue. |
| </p> |
| <p> |
| According to the OpenGL invariance rules, there's no guarantee that |
| the pixels produced by these two rendering states will match. |
| To achieve invariance, both passes should enable polygon stipple and |
| blending with appropriate patterns/modes to ensure the same fragments |
| are produced in both passes. |

| <h1>VMware guest GL driver</h1> |
| <p> |
| This page describes how to build, install and use the |
| <a href="http://www.vmware.com/">VMware</a> guest GL driver |
| (aka the SVGA or SVGA3D driver) for Linux using the latest source code. |
| This driver gives a Linux virtual machine access to the host's GPU for |
| hardware-accelerated 3D. |
| VMware Workstation running on Linux or Windows and VMware Fusion running on |
| MacOS are all supported. |
| </p> |
| <p> |
| End users shouldn't have to go through all these steps once the driver is |
| included in newer Linux distributions. |
| Fedora 18 and Ubuntu 12.10 include the VMware guest GL driver, for example. |
| </p> |
| <p> |
| For more information about the X components see these wiki pages at x.org: |

| Driver Overview</a> |
| <li><a href="http://wiki.x.org/wiki/vmware/vmware3D"> |
| xf86-video-vmware Details</a> |
| </ul> |
| <h2>Components</h2> |
| The components involved in this include: |
| <ul> |
| <li>Linux kernel module: vmwgfx |
| <li>X server 2D driver: xf86-video-vmware |
| <li>User-space libdrm library |
| <li>Mesa/gallium OpenGL driver: "svga" |
| </ul> |
| <h2>Prerequisites</h2> |
| <ul> |
| <li>Kernel version at least 2.6.25 |
| <li>Xserver version at least 1.7 |
| <li>Ubuntu: For ubuntu you need to install a number of build dependencies. |
| <pre> |
| sudo apt-get install git-core |
| sudo apt-get install automake libtool libpthread-stubs0-dev |
| sudo apt-get install xserver-xorg-dev x11proto-xinerama-dev libx11-xcb-dev |
| sudo apt-get install libxcb-glx0-dev libxrender-dev |
| sudo apt-get build-dep libgl1-mesa-dri libxcb-glx0-dev |
| </pre> |
| <li>Fedora: For Fedora you also need to install a number of build dependencies. |
| <pre> |
| sudo yum install mesa-libGL-devel xorg-x11-server-devel xorg-x11-util-macros |
| sudo yum install libXrender-devel.i686 |
| sudo yum install automake gcc libtool expat-devel kernel-devel git-core |
| sudo yum install makedepend flex bison |
| </pre> |
| </ul> |
| <p> |
| Depending on your Linux distro, other packages may be needed. |
| The configure scripts should tell you what's missing. |
| </p> |
| <h2>Getting the Latest Source Code</h2> |
| Begin by saving your current directory location: |
| <pre> |
| export TOP=$PWD |
| </pre> |
| <ul> |
| <li>Mesa/Gallium master branch. This code is used to build libGL, and the direct rendering svga driver for libGL, vmwgfx_dri.so, and the X acceleration library libxatracker.so.x.x.x. |
| <pre> |
| git clone git://anongit.freedesktop.org/git/mesa/mesa |
| </pre> |
| <li>VMware Linux guest kernel module. Note that this repo contains the complete DRM and TTM code. The vmware-specific driver is really only the files prefixed with vmwgfx. |
| <pre> |
| git clone git://anongit.freedesktop.org/git/mesa/vmwgfx |
| </pre> |
| <li>libdrm, a user-space library that interfaces with drm. |
| Most distros ship with this but it's safest to install a newer version. |
| To get the latest code from git: |
| <pre> |
| git clone git://anongit.freedesktop.org/git/mesa/drm |
| </pre> |
| <li>xf86-video-vmware. The chainloading driver, vmware_drv.so, the legacy driver vmwlegacy_drv.so, and the vmwgfx driver vmwgfx_drv.so. |
| <pre> |
| git clone git://anongit.freedesktop.org/git/xorg/driver/xf86-video-vmware |
| </pre> |
| </ul> |
| <h2>Building the Code</h2> |
| <ul> |
| <li>Build libdrm: If you're on a 32-bit system, you should skip the --libdir configure option. Note also the comment about toolchain libdrm above. |
| <pre> |
| cd $TOP/drm |
| ./autogen.sh --prefix=/usr --libdir=/usr/lib64 |
| make |
| sudo make install |
| </pre> |
| <li>Build Mesa and the vmwgfx_dri.so driver, the vmwgfx_drv.so xorg driver, the X acceleration library libxatracker. |
| The vmwgfx_dri.so is used by the OpenGL libraries during direct rendering, |
| and by the Xorg server during accelerated indirect GL rendering. |
| The libxatracker library is used exclusively by the X server to do render, |
| copy and video acceleration: |
| <br> |
| The following configure options doesn't build the EGL system. |
| <br> |
| As before, if you're on a 32-bit system, you should skip the --libdir |
| configure option. |
| <pre> |
| cd $TOP/mesa |
| ./autogen.sh --prefix=/usr --libdir=/usr/lib64 --with-gallium-drivers=svga --with-dri-drivers= --enable-xa |
| make |
| sudo make install |
| </pre> |
| Note that you may have to install other packages that Mesa depends upon |
| if they're not installed in your system. You should be told what's missing. |
| <br> |
| <br> |
| <li>xf86-video-vmware: Now, once libxatracker is installed, we proceed with building and replacing the current Xorg driver. First check if your system is 32- or 64-bit. If you're building for a 32-bit system, you will not be needing the --libdir=/usr/lib64 option to autogen. |
| <pre> |
| cd $TOP/xf86-video-vmware |
| ./autogen.sh --prefix=/usr --libdir=/usr/lib64 |
| make |
| sudo make install |
| </pre> |
| <li>vmwgfx kernel module. First make sure that any old version of this kernel module is removed from the system by issuing |
| <pre> |
| sudo rm /lib/modules/`uname -r`/kernel/drivers/gpu/drm/vmwgfx.ko* |
| </pre> |
| Then |
| <pre> |
| cd $TOP/vmwgfx |
| make |
| sudo make install |
| sudo cp 00-vmwgfx.rules /etc/udev/rules.d |
| sudo depmod -ae |
| </pre> |
| Note: some distros put DRM kernel drivers in different directories. |
| For example, sometimes vmwgfx.ko might be found in |
| <code>/lib/modules/{version}/extra/vmwgfx.ko</code> or in |
| <code>/lib/modules/{version}/kernel/drivers/gpu/drm/vmwgfx/vmwgfx.ko</code>. |
| <p> |
| After installing vmwgfx.ko you might want to run the following command to |
| check that the new kernel module is in the expected place: |
| <pre> |
| find /lib/modules -name vmwgfx.ko -exec ls -l '{}' \; |
| </pre> |
| If you see the kernel module listed in more than one place, you may need to |
| move things around. |
| <p> |
| Finally, if you update your kernel you'll probably have to rebuild and |
| reinstall the vmwgfx.ko module again. |
| </ul> |
| Now try to load the kernel module by issuing |
| <pre> |
| sudo modprobe vmwgfx</pre> |
| Then type |
| <pre> |
| dmesg</pre> |
| to watch the debug output. It should contain a number of lines prefixed with "[vmwgfx]". |
| <p> |
| Then restart the Xserver (or reboot). |
| The lines starting with "vmwlegacy" or "VMWARE" in the file /var/log/Xorg.0.log |
| should now have been replaced with lines starting with "vmwgfx", indicating that |
| the new Xorg driver is in use. |
| </p> |
| <h2>Running OpenGL Programs</h2> |
| <p> |
| In a shell, run 'glxinfo' and look for the following to verify that the |
| driver is working: |
| </p> |
| <pre> |
| OpenGL vendor string: VMware, Inc. |
| OpenGL renderer string: Gallium 0.4 on SVGA3D; build: RELEASE; |
| OpenGL version string: 2.1 Mesa 8.0 |
| </pre> |
| <p> |
| If you don't see this, try setting this environment variable: |
| <pre> |
| export LIBGL_DEBUG=verbose</pre> |
| <p> |
| then rerun glxinfo and examine the output for error messages. |

| <div class="content"> |
| <h1>Xlib Software Driver</h1> |
| <p> |
| Mesa's Xlib driver provides an emulation of the GLX interface so that |
| OpenGL programs which use the GLX API can render to any X display, even |
| those that don't support the GLX extension. |
| Effectively, the Xlib driver converts all OpenGL rendering into Xlib calls. |
| </p> |
| <p> |
| The Xlib driver is the oldest Mesa driver and the most mature of Mesa's |
| software-only drivers. |
| </p> |
| <p> |
| Since the Xlib driver <em>emulates</em> the GLX extension, it's not |
| totally conformant with a true GLX implementation. |
| The differences are fairly obscure, however. |
| </p> |
| <p> |
| The unique features of the Xlib driver follows. |
| </p> |
| <h2>X Visual Selection</h2> |
| <p> |
| Mesa supports RGB(A) rendering into almost any X visual type and depth. |
| </p> |
| <p> |
| The glXChooseVisual function tries to choose the best X visual |
| for the given attribute list. However, if this doesn't suit your needs |
| you can force Mesa to use any X visual you want (any supported by your |
| X server that is) by setting the <b>MESA_RGB_VISUAL</b> and |
| <b>MESA_CI_VISUAL</b> |
| environment variables. |
| When an RGB visual is requested, glXChooseVisual |
| will first look if the MESA_RGB_VISUAL variable is defined. |
| If so, it will try to use the specified visual. |
| Similarly, when a color index visual is requested, glXChooseVisual will |
| look for the MESA_CI_VISUAL variable. |
| </p> |
| <p> |
| The format of accepted values is: <code>visual-class depth</code> |
| </p> |
| <p> |
| Here are some examples: |
| </p> |
| <pre> |
| using csh: |
| % setenv MESA_RGB_VISUAL "TrueColor 8" // 8-bit TrueColor |
| % setenv MESA_CI_VISUAL "PseudoColor 12" // 12-bit PseudoColor |
| % setenv MESA_RGB_VISUAL "PseudoColor 8" // 8-bit PseudoColor |
| using bash: |
| $ export MESA_RGB_VISUAL="TrueColor 8" |
| $ export MESA_CI_VISUAL="PseudoColor 12" |
| $ export MESA_RGB_VISUAL="PseudoColor 8" |
| </pre> |
| <h2>Double Buffering</h2> |
| <p> |
| Mesa can use either an X Pixmap or XImage as the back color buffer when in |
| double-buffer mode. |
| The default is to use an XImage. |
| The <b>MESA_BACK_BUFFER</b> environment variable can override this. |
| The valid values for <b>MESA_BACK_BUFFER</b> are: <b>Pixmap</b> and |
| <b>XImage</b> (only the first letter is checked, case doesn't matter). |
| </p> |
| <p> |
| Using XImage is almost always faster than a Pixmap since it resides in |
| the application's address space. |
| When glXSwapBuffers() is called, XPutImage() or XShmPutImage() is used |
| to transfer the XImage to the on-screen window. |
| </p> |
| <p> |
| A Pixmap may be faster when doing remote rendering of a simple scene. |
| Some OpenGL features will be very slow with a Pixmap (for example, blending |
| will require a round-trip message for pixel readback.) |
| </p> |
| <p> |
| Experiment with the MESA_BACK_BUFFER variable to see which is faster |
| for your application. |
| </p> |
| <h2>Colormaps</h2> |
| <p> |
| When using Mesa directly or with GLX, it's up to the application |
| writer to create a window with an appropriate colormap. The GLUT |
| toolkit tris to minimize colormap <em>flashing</em> by sharing |
| colormaps when possible. Specifically, if the visual and depth of the |
| window matches that of the root window, the root window's colormap |
| will be shared by the Mesa window. Otherwise, a new, private colormap |
| will be allocated. |
| </p> |
| <p> |
| When sharing the root colormap, Mesa may be unable to allocate the colors |
| it needs, resulting in poor color quality. This can happen when a |
| large number of colorcells in the root colormap are already allocated. |
| To prevent colormap sharing in GLUT, set the |
| <b>MESA_PRIVATE_CMAP</b> environment variable. The value isn't |
| significant. |
| </p> |
| <h2>Gamma Correction</h2> |
| <p> |
| To compensate for the nonlinear relationship between pixel values |
| and displayed intensities, there is a gamma correction feature in |
| Mesa. Some systems, such as Silicon Graphics, support gamma |
| correction in hardware (man gamma) so you won't need to use Mesa's |
| gamma facility. Other systems, however, may need gamma adjustment |
| to produce images which look correct. If you believe that |
| Mesa's images are too dim, read on. |
| </p> |
| <p> |
| Gamma correction is controlled with the <b>MESA_GAMMA</b> environment |
| variable. Its value is of the form <b>Gr Gg Gb</b> or just <b>G</b> where |
| Gr is the red gamma value, Gg is the green gamma value, Gb is the |
| blue gamma value and G is one gamma value to use for all three |
| channels. Each value is a positive real number typically in the |
| range 1.0 to 2.5. |
| The defaults are all 1.0, effectively disabling gamma correction. |
| Examples: |
| </p> |
| <pre> |
| % export MESA_GAMMA="2.3 2.2 2.4" // separate R,G,B values |
| % export MESA_GAMMA="2.0" // same gamma for R,G,B |
| </pre> |
| <p> |
| The <code>demos/gamma.c</code> program in mesa/demos repository may help |
| you to determine reasonable gamma value for your display. With correct |
| gamma values, the color intensities displayed in the top row (drawn by |
| dithering) should nearly match those in the bottom row (drawn as grays). |
| </p> |
| <p> |
| Alex De Bruyn reports that gamma values of 1.6, 1.6 and 1.9 work well |
| on HP displays using the HP-ColorRecovery technology. |
| </p> |
| <p> |
| Mesa implements gamma correction with a lookup table which translates |
| a "linear" pixel value to a gamma-corrected pixel value. There is a |
| small performance penalty. Gamma correction only works in RGB mode. |
| Also be aware that pixel values read back from the frame buffer will |
| not be "un-corrected" so glReadPixels may not return the same data |
| drawn with glDrawPixels. |
| </p> |
| <p> |
| For more information about gamma correction see: |
| <a href="http://www.inforamp.net/~poynton/notes/colour_and_gamma/GammaFAQ.html"> |
| the Gamma FAQ</a> |
| </p> |
| <h2>Overlay Planes</h2> |
| <p> |
| Hardware overlay planes are supported by the Xlib driver. To |
| determine if your X server has overlay support you can test for the |
| SERVER_OVERLAY_VISUALS property: |
| </p> |
| <pre> |
| xprop -root | grep SERVER_OVERLAY_VISUALS |
| </pre> |
| <h2>HPCR Dithering</h2> |
| <p> |
| If you set the <b>MESA_HPCR_CLEAR</b> environment variable then dithering |
| will be used when clearing the color buffer. This is only applicable |
| to HP systems with the HPCR (Color Recovery) feature. |
| This incurs a small performance penalty. |
| </p> |
| <h2>Extensions</h2> |
| <p> |
| The following MESA-specific extensions are implemented in the Xlib driver. |
| </p> |
| <h3>GLX_MESA_pixmap_colormap</h3> |
| <p> |
| This extension adds the GLX function: |
| </p> |
| <pre> |
| GLXPixmap glXCreateGLXPixmapMESA( Display *dpy, XVisualInfo *visual, |
| Pixmap pixmap, Colormap cmap ) |
| </pre> |
| <p> |
| It is an alternative to the standard glXCreateGLXPixmap() function. |
| Since Mesa supports RGB rendering into any X visual, not just True- |
| Color or DirectColor, Mesa needs colormap information to convert RGB |
| values into pixel values. An X window carries this information but a |
| pixmap does not. This function associates a colormap to a GLX pixmap. |
| See the xdemos/glxpixmap.c file for an example of how to use this |
| extension. |
| </p> |
| <p> |
| <a href="specs/MESA_pixmap_colormap.spec">GLX_MESA_pixmap_colormap specification</a> |
| </p> |
| <h3>GLX_MESA_release_buffers</h3> |
| <p> |
| Mesa associates a set of ancillary (depth, accumulation, stencil and |
| alpha) buffers with each X window it draws into. These ancillary |
| buffers are allocated for each X window the first time the X window |
| is passed to glXMakeCurrent(). Mesa, however, can't detect when an |
| X window has been destroyed in order to free the ancillary buffers. |
| </p> |
| <p> |
| The best it can do is to check for recently destroyed windows whenever |
| the client calls the glXCreateContext() or glXDestroyContext() |
| functions. This may not be sufficient in all situations though. |
| </p> |
| <p> |
| The GLX_MESA_release_buffers extension allows a client to explicitly |
| deallocate the ancillary buffers by calling glxReleaseBuffersMESA() |
| just before an X window is destroyed. For example: |
| </p> |
| <pre> |
| #ifdef GLX_MESA_release_buffers |
| glXReleaseBuffersMESA( dpy, window ); |
| #endif |
| XDestroyWindow( dpy, window ); |
| </pre> |
| <p> |
| <a href="specs/MESA_release_buffers.spec">GLX_MESA_release_buffers specification</a> |
| </p> |
| <p> |
| This extension was added in Mesa 2.0. |
| </p> |
| <h3>GLX_MESA_copy_sub_buffer</h3> |
| <p> |
| This extension adds the glXCopySubBufferMESA() function. It works |
| like glXSwapBuffers() but only copies a sub-region of the window |
| instead of the whole window. |
| </p> |
| <p> |
| <a href="specs/MESA_copy_sub_buffer.spec">GLX_MESA_copy_sub_buffer specification</a> |
| </p> |
| <p> |
| This extension was added in Mesa 2.6 |
| </p> |
