2010-03-15drm/i915: Use a dmi quirk to skip a broken SDVO TV output.Zhao Yakui
commit 6070a4a928f8c92b9fae7d6717ebbb05f425d6b2 upstream. This IBM system has a multi-function SDVO card that reports both VGA and TV, but the system has no TV connector. The TV connector always reported as connected, which would lead to poor modesetting choices. https://bugs.freedesktop.org/show_bug.cgi?id=25787 Signed-off-by: Zhao Yakui <yakui.zhao@intel.com> Tested-by: Vance <liangghv@sg.ibm.com> Signed-off-by: Eric Anholt <eric@anholt.net> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

So don't use it to detect LVDS presence, but leave the event handler to deal with lid open/close, when we might need to reset the mode.

2010-02-23drm/nv50: improve vram page table constructionBen Skeggs
This commit changes nouveau to construct PTEs which look very much like the ones the binary driver creates. I presume that filling multiple PTEs identically with length flags and the physical address of the start of a block of VRAM is a hint to the memory controller that it need not perform additional page table lookups for that range of addresses.

2010-02-22i915 / PM: Fix hibernate regression caused by suspend/resume splittingRafael J. Wysocki
Commit 84b79f8d2882b0a84330c04839ed4d3cefd2ff77 (drm/i915: Fix crash while aborting hibernation) attempted to fix a regression introduced by commit cbda12d77ea590082edb6d30bd342a67ebc459e0 (drm/i915: implement new pm ops for i915), but it went too far trying to split the freeze/suspend and resume/thaw parts of the code. As a result, it introduced another regression, which only is visible on some systems. Fix the problem by merging i915_drm_suspend() with i915_drm_freeze() and moving some code from i915_resume() into i915_drm_thaw(), so that intel_opregion_free() and intel_opregion_init() are also executed in the freeze and thaw code paths, respectively.

2010-02-18drm/radeon/kms: fix bo's fence associationJerome Glisse
Previous code did associate fence to bo before the fence was emited and it also didn't lock protected access to ttm sync_obj member. Both of this flaw leads to possible race between different code path. This patch fix this by associating fence only once the fence is emitted and properly lock protect access to sync_obj member of ttm.

2010-02-18drm/radeon/kms: fix indirect buffer management V2Jerome Glisse
There is 3 different distinct states for an indirect buffer (IB) : 1- free with no fence 2- free with a fence 3- non free (fence doesn't matter) Previous code mixed case 2 & 3 in a single one leading to possible catastrophique failure. This patch rework the handling and properly separate each case. So when you get ib we set the ib as non free and fence status doesn't matter. Fence become active (ie has a meaning for the ib code) once the ib is scheduled or free. This patch also get rid of the alloc bitmap as it was overkill, we know go through IB pool list like in a ring buffer as the oldest IB is the first one the will be free. Fix : https://bugs.freedesktop.org/show_bug.cgi?id=26438 and likely other bugs.

2010-02-11vgaarb: fix incorrect dereference of userspace pointer.Andy Getzendanner
This patch corrects a userspace pointer dereference in the VGA arbiter in 2.6.32.1. copy_from_user() is used at line 822 to copy the contents of buf into kbuf, but a call to strncmp() on line 964 uses buf rather than kbuf. This problem led to a GPF in strncmp() when X was started on my x86_32 systems. X triggered the behavior with a write of "target PCI:0000:01:00.0" to /dev/vga_arbiter. The patch has been tested against 2.6.32.1 and observed to correct the GPF observed when starting X or manually writing the string "target PCI:0000:01:00.0" to /dev/vga_arbiter.
