drm/i915/selftests: Flush GPU activity before completing live_contexts igt_ctx_exec() expects that we retire all active requests/objects before completing, so that when we clean up the files afterwards they are ready to be freed. Before we do so, it is then prudent to ensure that we have indeed retired the GPU activity, raising an error if it fails. If we do not, we run the risk of triggering an assertion when freeing the object: __i915_gem_free_objects:4793 GEM_BUG_ON(i915_gem_object_is_active(obj)) Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk> Reviewed-by: Mika Kuoppala <mika.kuoppala@linux.intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20180505091014.26126-2-chris@chris-wilson.co.uk
