/** @file gem_tiled_blits.c
*
* This is a test of doing many tiled blits, with a working set
* larger than the aperture size.
*
* The goal is to catch a couple types of failure;
* - Fence management problems on pre-965.
* - A17 or L-shaped memory tiling workaround problems in acceleration.
*
* The model is to fill a collection of 1MB objects in a way that can't trip
* over A6 swizzling -- upload data to a non-tiled object, blit to the tiled
* object. Then, copy the 1MB objects randomly between each other for a while.
* Finally, download their data through linear objects again and see what
* resulted.
