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