[Intel-gfx] [PATCH] drm/i915: Extend reset modparam to domain resets

2019-11-20 Thread Stuart Summers
In the event a platform does not properly implement reset, do not go through reset flows for engine domains to avoid an unlikely situation where writes are accepted but register values are never cleared, as this can result in GPU wedges in these cases. Signed-off-by: Stuart Summers --- drivers/g
