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