2010-12-05drm/i915/lvds: Always restore panel-fitter when enabling the LVDSChris Wilson
Linus Torvalds pointed out that our code was unbalanced when powering on the panel with respect to the power off sequence in that we were failing to restore the panel-fitter. The consequence of this would be that across a simple DPMS off/on for a non-native mode, without an intervening modeset, the panel fitter would remain disabled and the output would shift on the panel.

2010-12-05drm/i915/ringbuffer: Only print an error on the second attempt to reset headChris Wilson
There's not much we can do here but hope for the best. However the first failure happens quite frequently and if often remedied by the second attempt to reset HEAD. So only print the error if that attempt also fails.

2010-12-05drm/i915: announce to userspace that the bsd ring is coherentDaniel Vetter
Otherwise we can't really fix the abi-braindeadness of forcing libva to manually wait for rendering when switching rings. Which in turn makes implementing hw semaphores a pointless exercise (at least for ironlake). [Also added the relaxed fencing param to explain the jump in numbering - relaxed fencing is in -next.] Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch> Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>

2010-12-05drm/i915: Implement GPU semaphores for inter-ring synchronisation on SNBChris Wilson

2010-12-03drm/i915: Clean conflicting modesetting registers upon initChris Wilson
If we leave the registers in a conflicting state then when we attempt to teardown the active mode, we will not disable the pipes and planes in the correct order -- leaving a plane reading from a disabled pipe and possibly leading to undefined behaviour.

2010-12-03drm/nouveau: fix annoying nouveau_fence type issueMarcin Slusarz
nouveau_fence_* functions are not type safe, which could lead to bugs. Additionally every use of nouveau_fence_unref had to cast struct nouveau_fence to void **. Fix it by renaming old functions and creating static inline functions with new prototypes. We still need old functions, because we pass function pointers to ttm. As we are wrapping functions, drop unused "void *arg" parameter where possible.

2010-12-03drm/nouveau: add support for MSIBen Skeggs
Only supported on NV50+ so far, and disabled by default currently. The module parameter "msi=1" will enable it. There's a kernel bug which will cause this to fail if the module (or the NVIDIA binary driver) has ever been loaded before loading nouveau with MSI enabled. As such, this is only safe to enable if you have nouveau load on boot, and don't wish to ever reload it. The workaround is to "echo 0 > /sys/bus/pci/devices/<device>/enable" until the enable count reads 0. Then you should be able to load nouveau with MSI enabled.
