2017-08-18drm/i915: Don't use MI_STORE_DWORD_IMM on Sandybridge/vcsChris Wilson1-6/+12
MI_STORE_DWORD_IMM just doesn't work on the video decode engine under Sandybridge, so refrain from using it. Then switch the selftests over to using the now common test prior to using MI_STORE_DWORD_IMM.

2017-08-04drm/i915/selftests: Retarget igt_render_engine_reset_fallback()Chris Wilson1-57/+17
The purpose of the test was to check per-engine resets would fallback to the global reset when required, but first we actually need a test for a basic i915_handle_error()!

2017-07-27drm/i915: Squelch reset messages during selftestsChris Wilson1-4/+4
During our selftests, we try reseting the GPU tens of thousands of times, flooding the dmesg with our reset spam drowning out any potential warnings. Add an option to i915_reset()/i915_reset_engine() to specify a quiet reset for selftesting.

Extract the common barrier against rogue hangchecks from disrupting our direct testing of resets, and in the process expand the lock to include the per-engine reset shortcuts.

2017-07-27drm/i915/selftests: Exercise independence of per-engine resetsChris Wilson1-0/+164
If all goes well, resetting one engine should not affect the operation of any others. So to test this, we setup a continuous stream of requests onto to each of the "innocent" engines whilst constantly resetting our target engine.

2017-06-20drm/i915: Wait for concurrent global resets to completeChris Wilson1-0/+4
If we enter i915_handle_error() a second time and a global reset is already in progress, we can simply wait for completion of the first reset. Currently we exit early prior to the actual reset being performed -- the worst of both worlds! v2: Plug into the existing reset_queue, and remember that kselftests is playing games with I915_RESET_BACKOFF to prevent hangcheck from screwing up. v3: Rename to i915_reset_device to fit in better with i915_reset_engine Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk> Cc: Mika Kuoppala <mika.kuoppala@linux.intel.com> Cc: Michel Thierry <michel.thierry@intel.com> Reviewed-by: Michel Thierry <michel.thierry@intel.com> Link: http://patchwork.freedesktop.org/patch/msgid/20170620095751.13127-2-chris@chris-wilson.co.uk

2017-03-16drm/i915: Split I915_RESET_IN_PROGRESS into two flagsChris Wilson1-6/+12
I915_RESET_IN_PROGRESS is being used for both signaling the requirement to i915_mutex_lock_interruptible() to avoid taking the struct_mutex and to instruct a waiter (already holding the struct_mutex) to perform the reset. To allow for a little more coordination, split these two meaning into a couple of distinct flags. I915_RESET_BACKOFF tells i915_mutex_lock_interruptible() not to acquire the mutex and I915_RESET_HANDOFF tells the waiter to call i915_reset().
