2017-02-17drm/i915/glk: Load the degamma LUT even in legacy gamma modeAnder Conselvan de Oliveira
In Geminilake, the degamma table is enabled or disabled by the pipe CSC enable bit, so its active even when running in the legacy gamma mode. So always set sane values for that table, since the default value is all zeroes. This fixes blank screens after a suspend/resume cycle while legacy gamma is in use.

2017-02-17drm/i915: Consolidate gen8_emit_pipe_controlTvrtko Ursulin
We have a few open coded instances in the execlists code and an almost suitable helper in intel_ringbuf.c We can consolidate to a single helper if we change the existing helper to emit directly to ring buffer memory and move the space reservation outside it. v2: Drop memcpy for memset.

2017-02-17drm/i915: Tidy workaround batch buffer emissionTvrtko Ursulin
Use the "*batch++ = " style as in the ring emission for better readability and also simplify the logic a bit by consolidating the offset and size calculations and overflow checking. The latter is a programming error so it is not required to check for it after each write to the object, but rather do it once the whole state has been written and fail the driver if something went wrong. v2: Rebase. v3: Keep track of offsets and sizes in bytes for simplicity and rename function pointer variable to _fn suffix. (Chris Wilson) v4: Fix size calc broken in v3 and add alignment warning. (Chris Wilson) v5: Fix return code. v6: I added an exit from loop in v5 but forgot to put back the object teardown.

There are instances (such as non-recoverable GPU page faults) where NVKM decides that a channel's context is no longer viable, and will be removed from the runlist. This commit notifies the owner of the channel when this happens, so it has the opportunity to take some kind of recovery action instead of hanging. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

2017-02-17drm/nouveau/drm/nouveau/led: prevent a possible use-after-freeMartin Peres
