Preempt-to-busy allows replacement of an\nactive request that may complete before the preemption is processed by\nHW. If that happens, the request is retired from the queue, but the\nqueue_priority_hint remains set, preventing direct submission until\nafter the next CS interrupt is processed.\n\nThis preempt-to-busy race can be triggered by the heartbeat, which will\nalso act as the power-management barrier and upon completion allow us to\nidle the HW. We may process the completion of the heartbeat, and begin\nparking the engine before the CS event that restores the\nqueue_priority_hint, causing us to fail the assertion that it is MIN.\n\n<3>[
