Chris Wilson f9e9e9de58 drm/i915: Prioritise non-busywait semaphore workloads ... We don't want to busywait on the GPU if we have other work to do. If we give non-busywaiting workloads higher (initial) priority than workloads that require a busywait, we will prioritise work that is ready to run immediately. We then also have to be careful that we don't give earlier semaphores an accidental boost because later work doesn't wait on other rings, hence we keep a history of semaphore usage of the dependency chain. v2: Stop rolling the bits into a chain and just use a flag in case this request or any of our dependencies use a semaphore. The rolling around was contagious as Tvrtko was heard to fall off his chair.
