2009-06-15drm/r128: fix r128 ioremaps to use ioremap_wc.Dave Airlie
commit 42beefc0093725ec0f8cea340cc54c36ccaceea0 upstream. This should allow r128 to start working again since PAT changes. taken from F-11 kernel.

2009-05-08drm/i915: allow tiled front buffers on 965+Jesse Barnes
commit f544847fbaf099278343f875987a983f2b913134 upstream. This patch corrects a pretty big oversight in the KMS code for 965+ chips. The current code is missing tiled surface register programming, so userland can allocate a tiled surface and use it for mode setting, resulting in corruption. This patch fixes that, allowing for tiled front buffers on 965+.

2009-05-08drm/i915: add support for G41 chipsetZhenyu Wang
commit 72021788678523047161e97b3dfed695e802a5fd upstream. This had been delayed for some time due to failure to work on the one piece of G41 hardware we had, and lack of success reports from anybody else. Current hardware appears to be OK.

2009-03-11drm/i915: fix 945 fence register writes for fence 8 and above.Eric Anholt
The last 8 fence registers sit at a different offset, so when we went to set fence number 8 in the lower offset, we instead set PGETBL_CTL, and the GPU got all sorts of angry at us. fd.o bug #20567.

2009-03-11drm/i915: Protect active fences on i915Chris Wilson
The i915 also uses the fence registers for GPU access to tiled buffers so we cannot reallocate one whilst it is on the active list.

2009-03-03drm: Avoid client deadlocks when the master disappears.Thomas Hellstrom
This is done by 1) Wake up lock waiters when we close the master file descriptor. Not when the master structure is removed, since the latter requires the waiters themselves to release the refcount on the master structure -> Deadlock. 2) Send a SIGTERM to all clients waiting for the lock. Normally these clients will get a SIGPIPE when the X server dies, but clients may also spin trying to grab the DRM lock, without getting any sort of notification.

2009-02-25drm: edid revision 0 is validKyle McMartin
edid->revision == 0 should be valid (at least, so the error message indicates. :) and wikipedia seems to indicate that EDID 1.0 existed. We can dump the entire check, since edid->revision is a u8, so it can't ever be less than 0. Marko reports in RH bz#476735 that his monitor claims to be EDID 1.0, and therefore hits the check and is stuck at 800x600 because of it.

2009-02-25drm: Correct unbalanced drm_vblank_put() during mode setting.Chris Wilson
The first time we install a mode, the vblank will be disabled for a pipe and so drm_vblank_get() in drm_vblank_pre_modeset() will fail. As we unconditionally call drm_vblank_put() afterwards, the vblank reference counter becomes unbalanced.

2009-02-23drm/i915: Don't let a device flush to prepare buffers clear new write_domains.Eric Anholt
The problem was that object_set_to_gpu_domain would set the new write_domains that are getting set by this batchbuffer, then the accumulated flushes required for all the objects in preparation for this batchbuffer were posted, and the brand new write domain would get cleared by the flush being posted. Instead, hang on to the new (or old if we're not changing it) value and set it after the flush is queued. Results from this noticably included conformance test failures from reads shortly after writes (where the new write domain had been lost and thus not flushed and waited on), but is a suspected cause of hangs in some apps when a write domain is lost on a buffer that gets reused for instruction or commmand state.
