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