  49 /* Interface history:
  50  *
  51  * 1.1 - ??
  52  * 1.2 - Add vertex2 ioctl (keith)
  53  *     - Add stencil capability to clear ioctl (gareth, keith)
  54  *     - Increase MAX_TEXTURE_LEVELS (brian)
  55  * 1.3 - Add cmdbuf ioctl (keith)
  56  *     - Add support for new radeon packets (keith)
  57  *     - Add getparam ioctl (keith)
  58  *     - Add flip-buffers ioctl, deprecate fullscreen foo (keith).
  59  * 1.4 - Add scratch registers to get_param ioctl.
  60  * 1.5 - Add r200 packets to cmdbuf ioctl
  61  *     - Add r200 function to init ioctl
  62  *     - Add 'scalar2' instruction to cmdbuf
  63  * 1.6 - Add static GART memory manager
  64  *       Add irq handler (won't be turned on unless X server knows to)
  65  *       Add irq ioctls and irq_active getparam.
  66  *       Add wait command for cmdbuf ioctl
  67  *       Add GART offset query for getparam
  68  * 1.7 - Add support for cube map registers: R200_PP_CUBIC_FACES_[0..5]
  69  *       and R200_PP_CUBIC_OFFSET_F1_[0..5].
  70  *       Added packets R200_EMIT_PP_CUBIC_FACES_[0..5] and
  71  *       R200_EMIT_PP_CUBIC_OFFSETS_[0..5].  (brian)
  72  * 1.8 - Remove need to call cleanup ioctls on last client exit (keith)
  73  *       Add 'GET' queries for starting additional clients on different VT's.
  74  * 1.9 - Add DRM_IOCTL_RADEON_CP_RESUME ioctl.
  75  *       Add texture rectangle support for r100.
  76  * 1.10- Add SETPARAM ioctl; first parameter to set is FB_LOCATION, which
  77  *       clients use to tell the DRM where they think the framebuffer is
  78  *       located in the card's address space
  79  * 1.11- Add packet R200_EMIT_RB3D_BLENDCOLOR to support GL_EXT_blend_color
  80  *       and GL_EXT_blend_[func|equation]_separate on r200
  81  * 1.12- Add R300 CP microcode support - this just loads the CP on r300
  82  *       (No 3D support yet - just microcode loading).
  83  * 1.13- Add packet R200_EMIT_TCL_POINT_SPRITE_CNTL for ARB_point_parameters
  84  *     - Add hyperz support, add hyperz flags to clear ioctl.
  85  * 1.14- Add support for color tiling
  86  *     - Add R100/R200 surface allocation/free support
  87  * 1.15- Add support for texture micro tiling
  88  *     - Add support for r100 cube maps
  89  * 1.16- Add R200_EMIT_PP_TRI_PERF_CNTL packet to support brilinear
  90  *       texture filtering on r200
  91  * 1.17- Add initial support for R300 (3D).
  92  * 1.18- Add support for GL_ATI_fragment_shader, new packets
  93  *       R200_EMIT_PP_AFS_0/1, R200_EMIT_PP_TXCTLALL_0-5 (replaces
  94  *       R200_EMIT_PP_TXFILTER_0-5, 2 more regs) and R200_EMIT_ATF_TFACTOR
  95  *       (replaces R200_EMIT_TFACTOR_0 (8 consts instead of 6)
  96  * 1.19- Add support for gart table in FB memory and PCIE r300
  97  * 1.20- Add support for r300 texrect
  98  * 1.21- Add support for card type getparam
  99  * 1.22- Add support for texture cache flushes (R300_TX_CNTL)
 100  * 1.23- Add new radeon memory map work from benh
 101  * 1.24- Add general-purpose packet for manipulating scratch registers (r300)
 102  * 1.25- Add support for r200 vertex programs (R200_EMIT_VAP_PVS_CNTL,
 103  *       new packet type)
 104  * 1.26- Add support for variable size PCI(E) gart aperture
 105  * 1.27- Add support for IGP GART
 106  * 1.28- Add support for VBL on CRTC2
 107  * 1.29- R500 3D cmd buffer support
 108  * 1.30- Add support for occlusion queries
 109  * 1.31- Add support for num Z pipes from GET_PARAM
 110  * 1.32- fixes for rv740 setup
 111  * 1.33- Add r6xx/r7xx const buffer support
 112  * 1.34- fix evergreen/cayman GS register
