This directory contains a Gallium3D pipe driver which traces all incoming calls.
To build, invoke scons on the top dir as
scons statetrackers=mesa drivers=softpipe,i915simple,trace winsys=xlib
To use do
ln -s libGL.so build/linux-x86-debug/gallium/winsys/xlib/libGL.so.1
export LD_LIBRARY_PATH=$PWD/build/linux-x86-debug/gallium/winsys/xlib
export GALLIUM_TRACE=y
ensure the right libGL.so is being picked by doing
ldd `which glxinfo`
and then try running
glxinfo
which should create a gallium.*.trace file, which is an XML file. You can view
copying trace.xsl and trace.css to the same directory, and opening with a
XSLT capable browser like Firefox or Internet Explorer. It often happens that
the trace file was not properly terminated, and a
</trace>
closing tag is missing from the file end. Add it before try to open or
further transform it by doing
echo '</trace>' >> gallium.??.trace
This is still work in progress, namely:
- surface writes are not traced
- no way to know the start/end of a frame
