Chris Wilson 3adee4ac29 drm/i915: Soften the tasklet flush frequency before waits ... We include a tasklet flush before waiting on a request as a precaution against the HW being lax in event signaling. We now have a precautionary flush in the engine's heartbeat and so do not need to be quite so zealous on every request wait. If we focus on the request, the only tasklet flush that matters is if there is a delay in submitting this request to HW, so if the request is not ready to be executed, no advantage in reducing this wait can be gained by running the tasklet. And there is little point in doing busy work for no result.
