/** @file intel_aub.h
 *
 * The AUB file is a file format used by Intel's internal simulation
 * and other validation tools.  It can be used at various levels by a
 * driver to input state to the simulated hardware or a replaying
 * debugger.
 *
 * We choose to dump AUB files using the trace block format for ease
 * of implementation -- dump out the blocks of memory as plain blobs
 * and insert ring commands to execute the batchbuffer blob.
