[Intel-gfx] [PATCH] drm/i915: Soften the tasklet flush frequency before waits

[Intel-gfx] [PATCH] drm/i915: Soften the tasklet flush frequency before waits

[Chris Wilson]

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.
