commit 3fb04cb0bea5c68c23eaf0cfbd4de840a7948ee9 Author: Chris Wilson <chris@chris-wilson.co.uk> Date: Sun Dec 17 13:28:52 2017 +0000 drm/i915/selftests: Fix up igt_reset_engine Now that we skip a per-engine reset on an idle engine, we need to update the selftest to take that into account. In the process, we find that we were not stressing the per-engine reset very hard, so add those missing active resets. v2: Actually test i915_reset_engine() by loading it with requests.
