Chris Wilson 5400367a86 drm/i915: Ensure the engine is idle before manually changing HWS ... During reset_all_global_seqno() on seqno rollover, we have to update the HWS. This causes all in flight requests to be completed, so first we wait. However, we were only waiting for the requests themselves to be completed and clearing out the waiter rbtrees - what I had missed was the extra reference in execlists->port[]. Since commit fe9ae7a3bf ("drm/i915/execlists: Detect an out-of-order context switch") we can detect when the request is retired before the context switch interrupt is completed. The impact should be neglible outside of debugging.
