  31  * evergreen cards need to use the 3D engine to blit data which requires
  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
  37  * shader instructions.
