Chris Wilson 01b8fdc522 drm/i915: Skip post-reset request emission if the engine is not idle ... Since commit 7b6da818d8 ("drm/i915: Restore the kernel context after a GPU reset on an idle engine") we submit a request following the engine reset. The intent is that we don't submit a request if the engine is busy (as it will restart active by itself) but we only checked to see if there were remaining requests in flight on the hardware and skipped checking to see if there were any ready requests that would be immediately submitted on restart (the same time as our new request would be). Having convinced the engine to appear idle in the previous patch, we can use intel_engine_is_idle() as a better test to only submit a new request if there are no pending requests. As it happens, this is tripping up igt/drv_selftest/live_hangcheck in CI as we overfill the kernel_context ringbuffer trigger an infinite recursion from within the reset.
