/* Interface history:
 *
 * 1.1 - ??
 * 1.2 - Add vertex2 ioctl (keith)
 *     - Add stencil capability to clear ioctl (gareth, keith)
 *     - Increase MAX_TEXTURE_LEVELS (brian)
 * 1.3 - Add cmdbuf ioctl (keith)
 *     - Add support for new radeon packets (keith)
 *     - Add getparam ioctl (keith)
 *     - Add flip-buffers ioctl, deprecate fullscreen foo (keith).
 * 1.4 - Add scratch registers to get_param ioctl.
 * 1.5 - Add r200 packets to cmdbuf ioctl
 *     - Add r200 function to init ioctl
 *     - Add 'scalar2' instruction to cmdbuf
 * 1.6 - Add static agp memory manager
 *       Add irq handler (won't be turned on unless X server knows to)
 *       Add irq ioctls and irq_active getparam.
 *       Add wait command for cmdbuf ioctl
 *       Add agp offset query for getparam
 * 1.7 - Add support for cube map registers: R200_PP_CUBIC_FACES_[0..5]
 *       and R200_PP_CUBIC_OFFSET_F1_[0..5].
 *       Added packets R200_EMIT_PP_CUBIC_FACES_[0..5] and
 *       R200_EMIT_PP_CUBIC_OFFSETS_[0..5].  (brian)
