Subject: [git pull] drm fixes for 2.6.27-rc5
Hi Linus,
Please pull the 'drm-fixes' branch from
ssh://master.kernel.org/pub/scm/linux/kernel/git/airlied/drm-2.6.git drm-fixes
This fixes two regressions, one in radeon suspend/resume, and one in
965/GM45 suspend/resume. It also removes a major racy piece of code for
doing vblank swaps, it really was never used properly and userspace never
relied on it being there. It also stops the drm binding twice to certain
Intel PCI devices where the second head isn't a real device but a dumb
placeholder.
Intel are working on some interrupt handling issues that we might have
some fixes for quite soon, and the AGP on PAE issue is still outstanding.
Dave.

drm/i915: Move legacy breadcrumb out of the reserved status page area
Addresses in the hardware status page below index 0x20 are reserved for use
by the hardware. The legacy breadcrumb was sitting at index 5. Move it to
index 0x21, and make sure everyone uses the defined value instead of
hard-coded constants.

drm/i915: Filter pci devices based on PCI_CLASS_DISPLAY_VGA
This fixes hangs on 855-class hardware by avoiding double attachment of the
driver due to the stub second head device having the same pci id as the real
device.
Other DRM drivers probably want this treatment as well, but I'm applying it
just to this one for safety. But we should clean up the drm_pciids.h mess
now so that each driver has its own pci id list header in its own directory.
Lets do that in the next release.

drm/radeon: map registers at load time
Now that the radeon driver has suspend/resume functions, it needs to map its
registers at load time or it will likely crash if a suspend operation occurs
before the driver has been initialized.
This patch moves the register mapping code from firstopen to load and makes
the mapping into a _DRM_DRIVER one so that the core won't remove it at
lastclose time.
Fixes (at least partially) kernel bz #11891.

drm: Remove infrastructure for supporting i915's vblank swapping.

i915: Remove racy delayed vblank swap ioctl.
When userland detected that this ioctl was supported (by version number check),
it used it in a racy way -- dispatch delayed swap, wait for vblank, continue
rendering. As there was no mechanism for it to wait for the swap to finish,
sometimes it would render before the swap and garbage would be displayed on
the screen.
By removing the ioctl and returning -EINVAL, userland returns to its previous,
correct rendering path of waiting for a vblank then dispatching a swap. The
only path that could have used this ioctl correctly was page flipping, which
relied on only one client running and emitting wait-for-vblank-before-rendering
in the command stream. That path also falls back correctly, at the performance
cost of not being able to queue up rendering before the flip occurs.

i915: Don't attempt to short-circuit object_wait_rendering by checking domains.
This could return early when reading after writing a buffer, if somebody
had already put it on the flushing list (write domains are 0, but still
active), leading to glReadPixels failure.

i915: Save/restore MCHBAR_RENDER_STANDBY on GM965/GM45
This register is set by the 2D driver to prevent lockups, and so it needs to
be preserved across suspend/resume too. This makes my X200s work.
