| 29 | * |
| 30 | * This is a test of doing many tiled blits, with a working set |
| 31 | * larger than the aperture size. |
| 32 | * |
| 33 | * The goal is to catch a couple types of failure; |
| 34 | * - Fence management problems on pre-965. |
| 35 | * - A17 or L-shaped memory tiling workaround problems in acceleration. |
| 36 | * |
| 37 | * The model is to fill a collection of 1MB objects in a way that can't trip |
| 38 | * over A6 swizzling -- upload data to a non-tiled object, blit to the tiled |
| 39 | * object. Then, copy the 1MB objects randomly between each other for a while. |
| 40 | * Finally, download their data through linear objects again and see what |
| 41 | * resulted. |
