     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.
