Dave Airlie 9a18664506 drm: 32/64-bit DRM ioctl compatibility patch
The patch is against a 2.6.11 kernel tree.  I am running this with a
32-bit X server (compiled up from X.org CVS as of a couple of weeks
ago) and 32-bit DRI libraries and clients.  All the userland stuff is
identical to what I am using under a 32-bit kernel on my G4 powerbook
(which is a 32-bit machine of course).  I haven't tried compiling up a
64-bit X server or clients yet.

In the compatibility routines I have assumed that the kernel can
safely access user addresses after set_fs(KERNEL_DS).  That is, where
an ioctl argument structure contains pointers to other structures, and
those other structures are already compatible between the 32-bit and
64-bit ABIs (i.e. they only contain things like chars, shorts or
ints), I just check the address with access_ok() and then pass it
through to the 64-bit ioctl code.  I believe this approach may not
work on sparc64, but it does work on ppc64 and x86_64 at least.

One tricky area which may need to be revisited is the question of how
to handle the handles which we pass back to userspace to identify
mappings.  These handles are generated in the ADDMAP ioctl and then
passed in as the offset value to mmap.  However, offset values for
mmap seem to be generated in other ways as well, particularly for AGP
mappings.

The approach I have ended up with is to generate a fake 32-bit handle
only for _DRM_SHM mappings.  The handles for other mappings (AGP, REG,
FB) are physical addresses which are already limited to 32 bits, and
generating fake handles for them created all sorts of problems in the
mmap/nopage code.

This patch has been updated to use the new compatibility ioctls.

/* 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
* 1.12- Add R300 CP microcode support - this just loads the CP on r300
* (No 3D support yet - just microcode loading)
* 1.13- Add packet R200_EMIT_TCL_POINT_SPRITE_CNTL for ARB_point_parameters
* - Add hyperz support, add hyperz flags to clear ioctl.
* 1.14- Add support for color tiling
* - Add R100/R200 surface allocation/free support
* 1.15- Add support for texture micro tiling
* - Add support for r100 cube maps
* 1.16- Add R200_EMIT_PP_TRI_PERF_CNTL packet to support brilinear
* texture filtering on r200
