[Intel-gfx] [PATCH 1/2] drm/i915/selftests: Restore previous heartbeat interval

[Chris Wilson]

Use the defaults we store on the engine when resetting the heartbeat as
we may have had to adjust it from the config value during initialisation.

[Intel-gfx] [PATCH 2/2] drm/i915/gt: Ratelimit heartbeat completion probing

[Chris Wilson]

The heartbeat runs through a few phases that we expect to complete
within a certain number of heartbeat intervals. First we must submit the
heartbeat to the queue, and if the queue is occupied it may take a
couple of intervals before the heartbeat preempts the workload and is
submitted to HW. Once running on HW, completion is not instantaneous as
it may have to first reset the current workload before it itself runs
through the empty request and signals completion. As such, we know that
the heartbeat must take at least the preempt reset timeout and before we
have had a chance to reset the engine, we do not want to issue a global
reset ourselves (simply so that we only try to do one reset at a time
and not confuse ourselves by resetting twice and hitting an innocent.)

So by taking into consideration that once running the request must take
a finite amount of time, we can delay the final completion check to
accommodate that and avoid checking too early (before we've had a chance
to handle any engine resets required).

v2: Attach a callback to flush the work immediately upon the heartbeat
completion and insert the delay before the next.
