Use rcu_read_lock to read p->event_idr concurrently with other readers and writers. Use p->event_mutex only for creating and destroying events and in kfd_wait_on_events. Protect the contents of the kfd_event structure with a per-event spinlock that can be taken inside the rcu_read_lock critical section. This eliminates contention of p->event_mutex in set_event, which tends to be on the critical path for dispatch latency even when busy waiting is used. It also eliminates lock contention in event interrupt handlers. Since the p->event_mutex is now used much less, the impact of requiring it in kfd_wait_on_events should also be much smaller. This should improve event handling latency for processes using multiple GPUs concurrently. v2: Reschedule the worker periodically to avoid soft lockup warnings Signed-off-by:
