  31 /*
  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.
