[Intel-gfx] [PATCH 2/2] intel: Add .aub file output support.
Eric Anholt

Wed Mar 7 20:21:07 CET 2012
From: Kenneth Graunke <kenneth at whitecape.org>
This will allow the driver to capture all of its execution state to a
file for later debugging. intel_gpu_dump is limited in that it only
captures batchbuffers, and Mesa's captures, while more complete, still
capture only a portion of the state involved in execution.
It also enables us to load traces in our internal simulator.

+ *
+ * We choose to dump AUB files using the trace block format for ease

+ * and insert ring commands to execute the batchbuffer blob.
