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. Easily reproducible by running glxgears and killing it about 6 times. Signed-off-by: Eric Anholt <eric@anholt.net>
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. By performing a LRU scan of the fenced buffers we also avoid waiting the possibility of waiting on a pinned, or otherwise unusable, buffer.

2009-03-10drm/i915: Check to see if we've pinned all available fencesChris Wilson
We need to check and report if there are no available fences - or else we spin endlessly waiting for a buffer to magically unpin itself. Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk> Signed-off-by: Eric Anholt <eric@anholt.net>
2009-03-10drm/i915: Check fence status on every pin.Chris Wilson
As we may steal the fence register of an unpinned buffer for another, every time we repin the buffer we need to recheck whether it needs to be allocated a fence. Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk> Signed-off-by: Eric Anholt <eric@anholt.net>
2009-03-10drm/i915: First recheck for an empty fence register.Chris Wilson
If we wait upon a request and successfully unbind a buffer occupying a fence register, then that slot will be freed and cause a NULL derefrence upon rescanning. Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk> Signed-off-by: Eric Anholt <eric@anholt.net>

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.

2009-02-25drm: disable encoders before re-routing themJesse Barnes
In some cases we may receive a mode config that has a different CRTC<->encoder map that the current configuration. In that case, we need to disable any re-routed encoders before setting the mode, otherwise they may not pick up the new CRTC (if the output types are incompatible for example).

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.

2009-02-20drm/i915: Don't add panel_fixed_mode to the probed modes list at LVDS init.Steve Aarnio
In the case where no EDID data is read from the device, adding the panel_fixed_mode pointer to the probed modes list causes data corruption. If the panel_fixed_mode pointer is added to the probed modes list at init time, a copy of the mode is added again at drm_get_modes() request time. Then, the panel_fixed_mode pointer is freed because it is seen as a duplicate mode. Unfortunately, this pointer is still stored and used in mode_fixup(). Because the panel_fixed_mode data is copied and returned at drm_get_modes() time, it is unnecessary to add this information at init time.
