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.
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.
