摘要：
Techniques are described for determining a temporary latency tolerance report (tLTR) value. A processing unit has to respond to a device interrupt within a duration specified by tLTR to ensure no incoming data is lost due to device buffer overflow. The tLTR value can be used to prevent the processing unit from entering too deep a sleep state when a device driver anticipates multiple sequential interrupts for a transaction.
