AS Notify

AS Notify is a low-latency hardware-based thread wakeup mechanism. Instead of actively polling a Completion Queue (CQ), the user application can arm the CQ and issue a “wait” instruction to put the user thread to sleep. The user application will be woken up by AS_notify interrupt once a completion event takes place. Note that when AS_notify interrupt cannot be triggered, firmware will fall back into the traditional MSI interrupt.
