   29  *       Definitions for SVGA3D hardware capabilities.  Capabilities
   30  *       are used to query for optional rendering features during
   31  *       driver initialization. The capability data is stored as very
   32  *       basic key/value dictionary within the "FIFO register" memory
   33  *       area at the beginning of BAR2.
   34  *
   35  *       Note that these definitions are only for 3D capabilities.
   36  *       The SVGA device also has "device capabilities" and "FIFO
   37  *       capabilities", which are non-3D-specific and are stored as
   38  *       bitfields rather than key/value pairs.
