src/gallium/drivers/trace/README

   1 This directory contains a Gallium3D pipe driver which traces all incoming calls.

   3 To build, invoke scons on the top dir as
   4
   5  scons statetrackers=mesa drivers=softpipe,i915simple,trace winsys=xlib
   6
   7 To use do
   8
   9  ln -s libGL.so build/linux-x86-debug/gallium/winsys/xlib/libGL.so.1
  10  export LD_LIBRARY_PATH=$PWD/build/linux-x86-debug/gallium/winsys/xlib
  11  export GALLIUM_TRACE=y
  12
  13 ensure the right libGL.so is being picked by doing
  14
  15  ldd `which glxinfo`
  16
  17 and then try running
  18
  19  glxinfo
  20
  21 which should create a gallium.*.trace file, which is an XML file. You can view
  22 copying trace.xsl and trace.css to the same directory, and opening with a
  23 XSLT capable browser like Firefox or Internet Explorer.
  24
  25 This is still work in progress, namely:
  26 - surface writes are not traced
  27 - no way to know the start/end of a frame
