2015-05-21drm/i915/bxt: fix WaForceContextSaveRestoreNonCoherent on steppings B0+Imre Deak
On B0 and C0 steppings the workaround enable bit would be overriden by default, so the overriding must be disabled.

ARGB8888 is used for cursors on all platforms so we need to allow it everywhere. ABGR8888 is currently only honoured: - on VLV/CHV in sprite planes - on SKL+ for primary and sprite planes so only allow it for those platforms. Note that we only support ARGB8888/ABGR8888 on the primary plane for SKL/BXT because we have in line of sight the pipe bottom color on those platforms and because the primary plane programming on VLV/CHV doesn't anything different for those formats today. v2: Fix the logic to forbid the creation ABGR2101010 fbs (Ville) v3: Still allow the creation of ARGB8888 fbs now that cursor planes use real fb objects (found by PRTS).

2015-05-20drm/i915: Use uninterruptible mutex_lock for userptr bo creationChris Wilson
Mika encountered one pathological scenario under X where acquiring all the mm locks (required to insert a mmu notifier) was very slow, so slow that by the time we tried to lock the struct_mutex with the usual call to i915_mutex_lock_interruptible(), X's signal timer had fired causing us to restart the ioctl (and so looped indefinitely). While I suspect this is the result of another bug (something leaking mm perhaps?) we can forgo the error checking and interuptible nature of the lock here so we only have to pay the expense once and get on with it. This does expose the userptr creation routine to a driver livelock though by not being interruptible.

2015-05-20drm/i915: Don't overwrite (e)DP PLL selection on SKLAnder Conselvan de Oliveira
In the following commit, the place where the contents of dpll_hw_state in crtc_state where zeroed was changed. Prior to that commit, it happened when the new state was allocated, but now that happens just before the call the .crtc_compute_clock() hook. The DP code for SKL, however, sets up the (private) PLL in the encoder compute config function that has already run by the time that memset() is reached, causing the previous value to be lost. This patch fixes the issue by moving the memset() down the call chain, so that it is only called if the values in dpll_hw_state are going to be updated. commit 4978cc93d9ac240b435ce60431aef24239b4c270 Author: Ander Conselvan de Oliveira <ander.conselvan.de.oliveira@intel.com> Date: Tue Apr 21 17:13:21 2015 +0300 drm/i915: Preserve shared DPLL information in new pipe_config Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=90462 Signed-off-by: Ander Conselvan de Oliveira <ander.conselvan.de.oliveira@intel.com> Reviewed-by: Damien Lespiau <damien.lespiau@intel.com> Reported-and-tested-by: Tvrtko Ursulin <tvrtko.ursulin@linux.intel.com> Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch>

2015-05-20drm/i915: Make scaler_id check in check_crtc_state work for all gensChandra Konduru
During check_crtc_state, scaler_id mispatch is being reported for HSW. This is applicable for skl+ and not for HSW. It is introduced by commit id: commit a1b2278e4dfcd2dbea85e319ebf73a6b7b2f180b Author: Chandra Konduru <chandra.konduru@intel.com> Date: Tue Apr 7 15:28:45 2015 -0700 drm/i915: skylake panel fitting using shared scalers This patch will make sure that we leave scaler_id as 0 for platforms before skl and set for skl+ only. This way scaler_id check during check_crtc_state will pass for both prior to skl and skl+ platforms. v2: -Leave scaler_id as 0 for gen < 9 (Daniel) Signed-off-by: Chandra Konduru <chandra.konduru@intel.com> References: http://lists.freedesktop.org/archives/intel-gfx/2015-May/065741.html Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch>
2015-05-20drm/i915: Fix race on unreferencing the wrong mmio-flip-requestChris Wilson
As we perform the mmio-flip without any locking and then try to acquire the struct_mutex prior to dereferencing the request, it is possible for userspace to queue a new pageflip before the worker can finish clearing the old state - and then it will clear the new flip request. The result is that the new flip could be completed before the GPU has finished rendering. The bugs stems from removing the seqno checking in commit 536f5b5e86b225dab94c7ff8061ae482b6077387 Author: Ander Conselvan de Oliveira <ander.conselvan.de.oliveira@intel.com> Date: Thu Nov 6 11:03:40 2014 +0200 drm/i915: Make mmio flip wait for seqno in the work function Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk> Cc: Ander Conselvan de Oliveira <ander.conselvan.de.oliveira@intel.com> Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch>
2015-05-20drm/i915: Ensure cache flushes prior to doing CS flipsChris Wilson
Synchronising to an object active on the same ring is a no-op, for the benefit of execbuffer scheduler. However, for CS flips this means that we can forgo checking whether the last write request of the object is actually queued and more importantly whether the cache flush for the write was emitted.
