TRACE PIPE DRIVER

= About =

This directory contains a Gallium3D trace debugger pipe driver.

It can traces all incoming calls.

= Usage =

== Tracing ==

For tracing then do

 GALLIUM_TRACE=tri.trace trivial/tri

which should create a tri.trace file, which is an XML file. You can view copying

trace.xsl to the same directory, and opening with a XSLT capable browser such as

Firefox or Internet Explorer.

For long traces you can use the

  src/gallium/tools/trace/dump.py tri.trace | less -R

== Remote debugging ==

For remote debugging see:

  src/gallium/drivers/rbug/README

= Integrating =

You can integrate the trace pipe driver either inside the state tracker or the

target. The procedure on both cases is the same. Let's assume you have a

pipe_screen obtained by the usual means (variable and function names are just

for illustration purposes):

  real_screen = real_screen_create(...);

The trace screen is then created by doing

  trace_screen = trace_screen_create(real_screen);

You can then simply use trace_screen instead of real_screen.

You can create as many contexts you wish from trace_screen::context_create they

are automatically wrapped by trace_screen.
