43/* Interface history:
44 *
45 * 1.1 - ??
46 * 1.2 - Add vertex2 ioctl (keith)
47 * - Add stencil capability to clear ioctl (gareth, keith)
48 * - Increase MAX_TEXTURE_LEVELS (brian)
49 * 1.3 - Add cmdbuf ioctl (keith)
50 * - Add support for new radeon packets (keith)
51 * - Add getparam ioctl (keith)
52 * - Add flip-buffers ioctl, deprecate fullscreen foo (keith).
53 * 1.4 - Add scratch registers to get_param ioctl.
54 * 1.5 - Add r200 packets to cmdbuf ioctl
55 * - Add r200 function to init ioctl
56 * - Add 'scalar2' instruction to cmdbuf
57 * 1.6 - Add static GART memory manager
58 * Add irq handler (won't be turned on unless X server knows to)
59 * Add irq ioctls and irq_active getparam.
60 * Add wait command for cmdbuf ioctl
61 * Add GART offset query for getparam
62 * 1.7 - Add support for cube map registers: R200_PP_CUBIC_FACES_[0..5]
63 * and R200_PP_CUBIC_OFFSET_F1_[0..5].
64 * Added packets R200_EMIT_PP_CUBIC_FACES_[0..5] and
65 * R200_EMIT_PP_CUBIC_OFFSETS_[0..5]. (brian)
66 * 1.8 - Remove need to call cleanup ioctls on last client exit (keith)
67 * Add 'GET' queries for starting additional clients on different VT's.
68 * 1.9 - Add DRM_IOCTL_RADEON_CP_RESUME ioctl.
69 * Add texture rectangle support for r100.
70 * 1.10- Add SETPARAM ioctl; first parameter to set is FB_LOCATION, which
71 * clients use to tell the DRM where they think the framebuffer is
72 * located in the card's address space
73 * 1.11- Add packet R200_EMIT_RB3D_BLENDCOLOR to support GL_EXT_blend_color
74 * and GL_EXT_blend_[func|equation]_separate on r200
75 * 1.12- Add R300 CP microcode support - this just loads the CP on r300
76 * (No 3D support yet - just microcode loading)
77 * 1.13- Add packet R200_EMIT_TCL_POINT_SPRITE_CNTL for ARB_point_parameters
78 * - Add hyperz support, add hyperz flags to clear ioctl.
79 * 1.14- Add support for color tiling
80 * - Add R100/R200 surface allocation/free support
81 * 1.15- Add support for texture micro tiling
82 * - Add support for r100 cube maps
83 * 1.16- Add R200_EMIT_PP_TRI_PERF_CNTL packet to support brilinear
84 * texture filtering on r200
