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. -- Jose Fonseca
