<pre>Based on the age and addr hints, something to do with
static bool
need_timeslice(struct intel_engine_cs *engine, const struct i915_request *rq)
{
int hint;
if (!intel_engine_has_semaphores(engine))
return false;
if (list_is_last(&rq->sched.link, &engine->active.requests))
return false;
hint = max(rq_prio(list_next_entry(rq, sched.link)),
engine->execlists.queue_priority_hint);
return hint >= effective_prio(rq);
}
Likely suspect is *list_next_entry(rq, sched.link)</pre>
