/*
 * R6xx+ cards need to use the 3D engine to blit data which requires
 * quite a bit of hw state setup.  Rather than pull the whole 3D driver
 * (which normally generates the 3D state) into the DRM, we opt to use
 * statically generated state tables.  The regsiter state and shaders
 * were hand generated to support blitting functionality.  See the 3D
 * driver or documentation for descriptions of the registers and
 * shader instructions.
