I mean, I am using it in a combination with the intel_gpu_dump, based on
the original idea which came from
http://comments.gmane.org/gmane.comp.freedesktop.xorg.drivers.intel/6408,
only outside of the real intel_decode routine.

But yes, reading the code is the best way, the overall idea here is to at
least indicate which code to read in the first place (kernel or ddx or mesa
or va or....) :).
