drm/i915/selftests: exercise emit_pte() with nearly full ring
Simple regression test to check that we don't trample the
rq->reserved_space when returning from emit_pte(), if the ring is nearly
full.
v2: Make spinner_kill() static
v3: Reduce the ring size further, which should mean we need to execute less
noops; hopefully this appeases bsw. Also add some debug logging.
v4: Fix the min request construction to account for reserved_space +
I915_EMIT_PTE_NUM_DWORDS
v5: Use a simple on-stack timer to kill the spinner instead of kthread (Chris)
