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 register 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.
