3d1cc47037 drm/i915: Remove spurious warning "Failure to install fence"
This particular warning is harmless as we emit during the normal
pinning process where the batch buffer requires more fences than is
available without eviction. Only if we fail to evict enough fences does
this become a problem, so include the requested number of fences in the
ultimate *error* message.

v2: Remember to compile test even trial patches to remove warnings.

ac0c6b5ad3 drm/i915: Rebind bo if currently bound with incorrect alignment.
Whilst pinning the buffer, check that that its current alignment
matches the requested alignment. If it does not, rebind.

This should clear up any final render errors whilst resuming,

d13102c6b4 drm/nouveau: fix POST detection for certain chipsets
We totally fail at detecting un-POSTed chipsets prior to G80.  This commit
changes the pre-G80 POST detection to read the programmed horizontal total
from CRTC 0, and assume the card isn't POSTed if it's 0.

NVIDIA use some other heuristics more similar to what we do on G80, but I
wasted quite a long time trying to figure out the exact specifics of what
they do so we can try this for a bit instead.

9908ff736a drm/i915: Kill dangerous pending-flip debugging
We can, by virtue of a vblank interrupt firing in the middle of setting
up the unpin work (i.e. after we set the unpin_work field and before we
write to the ringbuffer) enter intel_finish_page_flip() prior to
receiving the pending flip notification. Therefore we can expect to hit
intel_finish_page_flip() under normal circumstances without a pending flip
and even without installing the pending_flip_obj. This is exacerbated by
aperture thrashing whilst binding the framebuffer

d1b851fc0d drm/i915: implement BSD ring buffer V2
The BSD (bit stream decoder) ring is used for accessing the BSD engine
which decodes video bitstream for H.264 and VC1 on G45+.  It is
asynchronous with the render ring and has access to separate parts of

79a78dd626 drm/i915: Fail to load driver if KMS request without GEM
The i915's implementation of KMS requires GEM in order to manage the
memory and execution domains of the framebuffer and associated

several subsystems. Rather than introducing a fragile unwind and attempt
to continue with UMS, spit out an error and unload the driver.

4a638b4e38 drm/edid: Allow non-fatal checksum errors in CEA blocks
Switches will try to update the topology address and not correctly fix
up the checksum, so just let it slide.

921d98b582 drm/radeon/kms: suppress a build warning (unused variable)
At least 'make CONFIG_DEBUG_SECTION_MISMATCH=y' causes
drivers/gpu/drm/radeon/atombios_crtc.c: In function 'atombios_crtc_set_pll':
drivers/gpu/drm/radeon/atombios_crtc.c:684: warning: 'pll' may be used uninitialized in this function
which has the looks of a falso positive.

Add a default: case so that gcc rests assured that all possible pll_id's are covered.
Keep the present cases that fall through to the default one for self-documentation.

I think it's good to release the AGP bridge at suspend
and reacquire it at resume. Also fix :
