  28 *
  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.
