47/* Interface history:
48 *
49 * 1.1 - ??
50 * 1.2 - Add vertex2 ioctl (keith)
51 * - Add stencil capability to clear ioctl (gareth, keith)
52 * - Increase MAX_TEXTURE_LEVELS (brian)
53 * 1.3 - Add cmdbuf ioctl (keith)
54 * - Add support for new radeon packets (keith)
55 * - Add getparam ioctl (keith)
56 * - Add flip-buffers ioctl, deprecate fullscreen foo (keith).
57 * 1.4 - Add scratch registers to get_param ioctl.
58 * 1.5 - Add r200 packets to cmdbuf ioctl
59 * - Add r200 function to init ioctl
60 * - Add 'scalar2' instruction to cmdbuf
61 * 1.6 - Add static GART memory manager
62 * Add irq handler (won't be turned on unless X server knows to)
63 * Add irq ioctls and irq_active getparam.
64 * Add wait command for cmdbuf ioctl
65 * Add GART offset query for getparam
66 * 1.7 - Add support for cube map registers: R200_PP_CUBIC_FACES_[0..5]
67 * and R200_PP_CUBIC_OFFSET_F1_[0..5].
68 * Added packets R200_EMIT_PP_CUBIC_FACES_[0..5] and
69 * R200_EMIT_PP_CUBIC_OFFSETS_[0..5]. (brian)
70 * 1.8 - Remove need to call cleanup ioctls on last client exit (keith)
71 * Add 'GET' queries for starting additional clients on different VT's.
72 * 1.9 - Add DRM_IOCTL_RADEON_CP_RESUME ioctl.
73 * Add texture rectangle support for r100.
74 * 1.10- Add SETPARAM ioctl; first parameter to set is FB_LOCATION, which
75 * clients use to tell the DRM where they think the framebuffer is
76 * located in the card's address space
77 * 1.11- Add packet R200_EMIT_RB3D_BLENDCOLOR to support GL_EXT_blend_color
78 * and GL_EXT_blend_[func|equation]_separate on r200
79 * 1.12- Add R300 CP microcode support - this just loads the CP on r300
80 * (No 3D support yet - just microcode loading).
81 * 1.13- Add packet R200_EMIT_TCL_POINT_SPRITE_CNTL for ARB_point_parameters
82 * - Add hyperz support, add hyperz flags to clear ioctl.
83 * 1.14- Add support for color tiling
84 * - Add R100/R200 surface allocation/free support
85 * 1.15- Add support for texture micro tiling
86 * - Add support for r100 cube maps
87 * 1.16- Add R200_EMIT_PP_TRI_PERF_CNTL packet to support brilinear
88 * texture filtering on r200
89 * 1.17- Add initial support for R300 (3D).
90 * 1.18- Add support for GL_ATI_fragment_shader, new packets
91 * R200_EMIT_PP_AFS_0/1, R200_EMIT_PP_TXCTLALL_0-5 (replaces
92 * R200_EMIT_PP_TXFILTER_0-5, 2 more regs) and R200_EMIT_ATF_TFACTOR
93 * (replaces R200_EMIT_TFACTOR_0 (8 consts instead of 6)
94 * 1.19- Add support for gart table in FB memory and PCIE r300
95 * 1.20- Add support for r300 texrect
96 * 1.21- Add support for card type getparam
97 * 1.22- Add support for texture cache flushes (R300_TX_CNTL)
98 * 1.23- Add new radeon memory map work from benh
99 * 1.24- Add general-purpose packet for manipulating scratch registers (r300)
100 * 1.25- Add support for r200 vertex programs (R200_EMIT_VAP_PVS_CNTL,
101 * new packet type)
102 * 1.26- Add support for variable size PCI(E) gart aperture
103 * 1.27- Add support for IGP GART
104 * 1.28- Add support for VBL on CRTC2
105 * 1.29- R500 3D cmd buffer support
106 * 1.30- Add support for occlusion queries
107 * 1.31- Add support for num Z pipes from GET_PARAM
108 * 1.32- fixes for rv740 setup
109 * 1.33- Add r6xx/r7xx const buffer support
110 * 1.34- fix evergreen/cayman GS register
