Since Matthew's efi/vga changes on non-EFI machines we were failing
to tell the vgaarb/switcheroo what the default device was, this
sets the default device in the quirk if none has been set before.

This fixes the switcheroo on my T410s.

- prep work for wait_rendering_timeout from Ben with some nice
 refactorings
- first set of infoframe fixes from Paulo for doubleclocked CEA modes
- improve pch pll handling from Jesse and Chris
- gpu hangman, this also contains the reset fix for gen4
- rps sanity check from Chris - this papers over issues when the gpu fails
 to clock up on snb/ivb, and it is shockingly easy to hit. The code
 prints a big WARN backtrace and restores the hw to a sane state. The
 real fix is still in the works.

Atm I'm aware of 2 regressions in -next:
- One of the gmbus patches (not gmbus itself) regressed lvds detection on
 a MacbookPro. I've analyzed the bug already and I think I know what's
 going on, patch is awaiting test feedback.
- Just today QA reported that DP on ilk regressed. That bug is fresh of
 the press and still awaiting detailed logfiles and the bisect result.
 The only thing that's clear atm is that -fixes works and -next doesn't.

12 years agodrm: pass dev to drm_vm_{open,close}_locked()
Rob Clark [Tue, 1 May 2012 16:04:51 +0000 (11:04 -0500)]
drm: pass dev to drm_vm_{open,close}_locked()

Previously these functions would assume that vma->vm_file was the
drm_file.  Although if in some cases if the drm driver needs to use
something else for the backing file (such as the tmpfs filp) then this
assumption is no longer true.  But vma->vm_private_data is still the
GEM object.

With this change, now the drm_device comes from the GEM object rather
than the drm_file so the driver is more free to play with vma->vm_file.

The scenario where this comes up is for mmap'ing of cached dmabuf's
for non-coherent systems, where the driver needs to use fault handling
and PTE shootdown to simulate coherency.  We can't use the vma->vm_file
of the dmabuf, which is using anon_inode's address_space.  The most
straightforward thing to do is to use the GEM object's obj->filp for
vma->vm_file in all cases, for which we need this patch.
