| 32 | * quite a bit of hw state setup. Rather than pull the whole 3D driver | ||
| 33 | * (which normally generates the 3D state) into the DRM, we opt to use | ||
| 34 | * statically generated state tables. The regsiter state and shaders | ||
| 35 | * were hand generated to support blitting functionality. See the 3D | ||
| 36 | * driver or documentation for descriptions of the registers and | ||
