[Intel-gfx] [PATCH 10/12] drm/i915/selftests: Replace an unbounded set-domain wait with a timeout

[Tvrtko Ursulin]

From: Chris Wilson <chris at chris-wilson.co.uk>

After the memory-region test completes, it flushes the test by calling
set-to-cpu-domain. Use the igt_flush_test as it includes a timeout,
recovery and reports and error for miscreant tests.
