Chris Wilson 9452302436 drm/i915/gt: Report the currently active execlists request ... Since commit 22b7a426bb ("drm/i915/execlists: Preempt-to-busy"), we prune the engine->active.requests list prior to preemption, thus removing the trace of the currently executing request. If that request hangs rather than be preempted, we conclude that no active request was on the GPU. Fortunately, this only impacts our debugging, and not our means of hang detection or recovery. v2: Use from to check the current iterator before continuing, and report active as NULL if the current request is already completed.
