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/auxiliary/driver_rbug/README
= Integrating =
You can integrate the trace pipe driver either inside the gallium frontend 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.
