+/** @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.
