* drm/radeon/kms: fix rs600 tlb flushJerome Glisse2010-04-26
| | | | | | | | | | | | | commit 30f69f3fb20bd719b5e1bf879339914063d38f47 upstream. Typo in in flush leaded to no flush of the RS600 tlb which ultimately leaded to massive system ram corruption, with this patch everythings seems to work properly.

* drm/radeon/kms: fix tv dac conflict resolverAlex Deucher2010-04-26
| | | | | | | | | | | | | | | | | commit 08d075116db3592db218bfe0f554cd93c9e12505 upstream. On systems with the tv dac shared between DVI and TV, we can only use the dac for one of the connectors. However, when using a digital monitor on the DVI port, you can use the dac for the TV connector just fine. Check the use_digital status when resolving the conflict.

| | * drm/nv50: improve vram page table constructionBen Skeggs2010-02-22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

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.
