Chris Wilson c3f1ed90e6 drm/i915/gt: Allow temporary suspension of inflight requests ... In order to support out-of-line error capture, we need to remove the active request from HW and put it to one side while a worker compresses and stores all the details associated with that request. (As that compression may take an arbitrary user-controlled amount of time, we want to let the engine continue running on other workloads while the hanging request is dumped.) Not only do we need to remove the active request, but we also have to remove its context and all requests that were dependent on it (both in flight, queued and future submission). Finally once the capture is complete, we need to be able to resubmit the request and its dependents and allow them to execute. v2: Replace stack recursion with a simple list. v3: Check all the parents, not just the first, when searching for a stuck ancestor!
