/* 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 GART 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 GART 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)
|
|
* 1.8 - Remove need to call cleanup ioctls on last client exit (keith)
|
|
* Add 'GET' queries for starting additional clients on different VT's.
|
|
* 1.9 - Add DRM_IOCTL_RADEON_CP_RESUME ioctl.
|
|
* Add texture rectangle support for r100.
|
|
* 1.10- Add SETPARAM ioctl; first parameter to set is FB_LOCATION, which
|
|
* clients use to tell the DRM where they think the framebuffer is
|
|
* located in the card's address space
|
|
* 1.11- Add packet R200_EMIT_RB3D_BLENDCOLOR to support GL_EXT_blend_color
|
|
* and GL_EXT_blend_[func|equation]_separate on r200
