[git pull] update the staging radeon kms driver

[Dave Airlie]

Hi Linus,

Please read below then think about pulling the 'drm-radeon-kms' branch from
ssh://master.kernel.org/pub/scm/linux/kernel/git/airlied/drm-2.6.git drm-radeon-kms

The radeon kms driver has gotten a lot of bugfixes and cleanups in the run 
up to using it in F12, I'm going to be pulling this tree in there, so I said I 
may as well offer it up for you to include. I've been careful to not touch 
any code outside the radeon kms and TTM code (I even dropped some patches 
that touched the main drm code). The only non-kms file touched is adding 
an export needed for TTM.

You can pull this if you want, the kms driver is under staging and I'd 
like to have a better working baseline in the 2.6.31 final kernel than 
what we have now.

Dave.

    drm/ttm: Fix ttm in-kernel copying of pages with non-standard caching attributes.
    
    For x86 this affected highmem pages only, since they were always kmapped
    cache-coherent, and this is fixed using kmap_atomic_prot().
    
    For other architectures that may not modify the linear kernel map we
    resort to vmap() for now, since kmap_atomic_prot() generally uses the
    linear kernel map for lowmem pages. This of course comes with a
    performance impact and should be optimized when possible.

    drm/radeon/kms: vram sizing on certain r100 chips needs workaround.
    
    If an rn50/r100/m6/m7 GPU has < 64MB RAM, i.e. 8/16/32, the
    aperture used to calculate the MC_FB_LOCATION needs to be worked
    out from the CONFIG_APER_SIZE register, and not the actual vram size.
    
    TTM VRAM size was also being initialised wrong, use actual vram size
    to initialise it.

    drm/radeon/kms: add initial colortiling support.
    
    This adds new set/get tiling interfaces where the pitch
    and macro/micro tiling enables can be set. Along with
    a flag to decide if this object should have a surface when mapped.
    
    The only thing we need to allocate with a mapped surface should be
    the frontbuffer. Note rotate scanout shouldn't require one, and
    back/depth shouldn't either, though mesa needs some fixes.
    
    It fixes the TTM interfaces along Thomas's suggestions, and I've tested
    the surface stealing code with two X servers and not seen any lockdep issues.
    
    I've stopped tiling the fbcon frontbuffer, as I don't see there being
    any advantage other than testing, I've left the testing commands in there,
    just flip the fb_tiled to true in radeon_fb.c
    
    Open: Can we integrate endian swapping in with this?
    
    Future features:
    texture tiling - need to relocate texture registers TXOFFSET* with tiling info.
    
    This also merges Michel's cleanup surfaces regs at init time patch
    even though it makes sense on its own, this patch really relies on it.
    
    Some PowerMac firmwares set up a tiling surface at the beginning of VRAM
    which messes us up otherwise.
    that patch is:

    drm/radeon: fix support for vline relocations.
    
    Userspace sends us a special relocation type to sync video/exa
    to vlines to avoid tearing, this deals with the relocation
    in the kernel, it picks the correct crtc and avoids issues
    where crtcs are disabled.
    
    This version also parses the wait until to make sure it isn't
    trying to do anything evil.

    drm/radeon/kms: respect TOM on rs100->rs480 IGP variants.
    
    Normally we are free to place VRAM where we want in the GPUs
    memory address space, however on IGP chips the VRAM is actual RAM,
    and no special translation or aperture is used inside the GPU MC.
    
    So when you move the VRAM aperture away from the TOM register,
    you actually move it into main memory and can trash things quite badly.
    
    This commit makes the code respect the TOM location for MC_FB_LOCATION.

    drm/radeon/kms: set crtc and cursor offsets correctly on legacy chips.
    
    The crtc and cursor offsets on the legacy chips are offset from
    DISPLAY_BASE_ADDR. The code worked if display base addr was at 0,
    but otherwise falls to pieces.

    drm/radeon/kms: remove IB flushing trick.
    
    If there is a problem then this is hiding it, we shouldn't
    ever need to flush the IB. Either the buffers are:
    
    WB - caching just works.
    WC - no need to do explicit flush, the MB + readback will do it

    drm/radeon/kms: mmio base/size should be resource_size_t.
    
    Unsigned long is incorrect for 64-bit resources on 32-bit hw.

    drm/radeon/kms: fix some GART table entry bugs.
    
    1. rv370 can accept 40-bit addresses - also at 24-bit shift not 4 bits
    2. rs480 table can be in 40-bit space. - 4 bit shift for top 8 bits
    3. rs480 table entries can be in 40-bit space.
