2014-02-07drm/i915: Disable dp aux irq on g4xDaniel Vetter
Apparently it's broken in the exact same way as the gmbus irq. For reference of the full story see commit c12aba5aa0e60b7947bc8b6ea25ef55c4acf81a4 Author: Jiri Kosina <jkosina@suse.cz> Date: Tue Mar 19 09:56:57 2013 +0100 drm/i915: stop using GMBUS IRQs on Gen4 chips The effect is that we have a storm of unclaimed interrupts on the legacy irq line. If that one is used by a different device then the kernel will complain and rather quickly kill the irq source. Which breaks any device trying to actually use the legacy irq line. This regression has been introduced commit 4aeebd7443e36b0a40032e518a9338f48bd27efc Author: Daniel Vetter <daniel.vetter@ffwll.ch> Date: Thu Oct 31 09:53:36 2013 +0100 drm/i915: dp aux irq support for g4x/vlv Note that disabling MSI works around the issue, but we can't do that since apparently then the hw will miss interrupts. At least if relevant comments in i915_irq.c are accurate. v2: Cross-reference dp aux and gmbus gen4 comments. v3: Consolidate harder into i915_drv.h as suggested by Chris.

2014-02-05drm/msm/mdp4: pageflip fixesRob Clark
Backport a few fixes found in the course of getting mdp5 working. There is a window of time after pageflip is requested, before we start scanning out the new fb (ie. while we are waiting for gpu). During that time we need to continue holding a reference to the still-current scanout fb, to avoid the backing gem bo's from being destroyed. Possibly a common mdp_crtc parent class could be useful to share some of this logic between mdp4_crtc and mdp5_crtc. OTOH, this all can be removed from the driver once atomic is in place, as plane/crtc updates get deferred until all fb's are ready before calling in to .page_flip(), etc. Signed-off-by: Rob Clark <robdclark@gmail.com>

Also make sure that all bound resources are put on the resource validate list. This is needed for legacy emulation, since legacy user-space drivers will typically not re-emit shader bindings. It also removes the requirement for user-space drivers to re-emit render-target- and texture bindings.
