commit 6b8eeca65b18ae77e175cc2b6571731f0ee413bf upstream. I've only seen this once, and I failed to capture the lockdep backtrace, but I did some investigations. If we are calling into the MST layer from EDID probing, we have the mode_config mutex held, if during that EDID probing, the MST hub goes away, then we can get a deadlock where the connector destruction function in the driver tries to retake the mode config mutex. This offloads connector destruction to a workqueue, and avoid the subsequenct lock ordering issue.

2015-06-15drm/i915: Always reset vma->ggtt_view.pages cache on unbindingChris Wilson
With the introduction of multiple views of an obj in the same vm, each vma was taught to cache its copy of the pages (so that different views could have different page arrangements). However, this missed decoupling those vma->ggtt_view.pages when the vma released its reference on the obj->pages. As we don't always free the vma, this leads to a possible scenario (e.g. execbuffer interrupted by the shrinker) where the vma points to a stale obj->pages, and explodes. Fixes regression from commit fe14d5f4e5468c5b80a24f1a64abcbe116143670 Author: Tvrtko Ursulin <tvrtko.ursulin@intel.com> Date: Wed Dec 10 17:27:58 2014 +0000 drm/i915: Infrastructure for supporting different GGTT views per object Tvrtko says, if someone else will be confused how this can happen, key is the reservation execbuffer path. That puts the VMA on the exec_list which prevents i915_vma_unbind and i915_gem_vma_destroy from fully destroying the VMA. So the VMA is left existing as an empty object in the list - unbound and disassociated with the backing store. Kind of a cached memory object. And then re-using it needs to clear the cached pages pointer which is fixed above.

2015-06-09drm/i915: Fix DDC probe for passive adaptersJani Nikula
Passive DP->DVI/HDMI dongles on DP++ ports show up to the system as HDMI devices, as they do not have a sink device in them to respond to any AUX traffic. When probing these dongles over the DDC, sometimes they will NAK the first attempt even though the transaction is valid and they support the DDC protocol. The retry loop inside of drm_do_probe_ddc_edid() would normally catch this case and try the transaction again, resulting in success. That, however, was thwarted by the fix for [1]: commit 9292f37e1f5c79400254dca46f83313488093825 Author: Eugeni Dodonov <eugeni.dodonov@intel.com> Date: Thu Jan 5 09:34:28 2012 -0200 drm: give up on edid retries when i2c bus is not responding This added code to exit immediately if the return code from the i2c_transfer function was -ENXIO in order to reduce the amount of time spent in waiting for unresponsive or disconnected devices. That was possible because the underlying i2c bit banging algorithm had retries of its own (which, of course, were part of the reason for the bug the commit fixes). Since its introduction in commit f899fc64cda8569d0529452aafc0da31c042df2e Author: Chris Wilson <chris@chris-wilson.co.uk> Date: Tue Jul 20 15:44:45 2010 -0700 drm/i915: use GMBUS to manage i2c links we've been flipping back and forth enabling the GMBUS transfers, but we've settled since then. The GMBUS implementation does not do any retries, however, bailing out of the drm_do_probe_ddc_edid() retry loop on first encounter of -ENXIO. This, combined with Eugeni's commit, broke the retry on -ENXIO. Retry GMBUS once on -ENXIO on first message to mitigate the issues with passive adapters. This patch is based on the work, and commit message, by Todd Previte <tprevite@gmail.com>.

2015-06-01drm/i915: Don't skip request retirement if the active list is emptyVille Syrjälä
Apparently we can have requests even if though the active list is empty, so do the request retirement regardless of whether there's anything on the active list. The way it happened here is that during suspend intel_ring_idle() notices the olr hanging around and then proceeds to get rid of it by adding a request. However since there was nothing on the active lists i915_gem_retire_requests() didn't clean those up, and so the idle work never runs, and we leave the GPU "busy" during suspend resulting in a WARN later.

2015-05-26drm/vgem: drop DRIVER_PRIME (v2)Rob Clark
For actual sharing of buffers with other drivers (ie. actual hardware) we'll need to pimp things out a bit better to deal w/ caching, multiple memory domains, etc. See thread: http://lists.freedesktop.org/archives/dri-devel/2015-May/083160.html But for the llvmpipe use-case this isn't a problem. Nor do we really need prime/dri3 (dri2 is sufficient). So until the other issues are sorted lets remove DRIVER_PRIME. v2: also drop the dead code [airlied: Okay I'm convinced this API could have a lot of use cases that are really really bad, yes the upload use case is valid however that isn't the only use case enabled, and if we allow all the other use cases, people will start to (ab)use them, and then they'll be ABI and my life will get worse, so disable PRIME for now] Acked-by: Thomas Hellstrom <thellstrom@vmware.com> Acked-by: Daniel Vetter <daniel.vetter@ffwll.ch> Signed-off-by: Rob Clark <robdclark@gmail.com> Signed-off-by: Dave Airlie <airlied@redhat.com>
2015-05-22drm/plane-helper: Adapt cursor hack to transitional helpersDaniel Vetter
In commit f02ad907cd9e7fe3a6405d2d005840912f1ed258 Author: Daniel Vetter <daniel.vetter@ffwll.ch> Date: Thu Jan 22 16:36:23 2015 +0100 drm/atomic-helpers: Recover full cursor plane behaviour we've added a hack to atomic helpers to never to vblank waits for cursor updates through the legacy apis since that's what X expects. Unfortunately we've (again) forgotten to adjust the transitional helpers. Do this now. This fixes regressions for drivers only partially converted over to atomic (like i915).

git://anongit.freedesktop.org/drm-intel into drm-fixes There's a stable backport from Ander [1] that combines this and a few other commits to fix the flickering on v4.0, reported in [2] among others.
