摘要： An indication that a subsystem is about to enter an idle state is received, and an original fire time for a next timer interrupt is determined. An idle state for a subsystem is selected based on the original fire time; and a new fire time for the next timer interrupt is determined based on the selected idle state to reduce timer interrupt latency. A current latency in exiting an idle state is measured. The measured latency is added to a running average of latencies for the idle state. A latency value is determined based on the running average and a worst case latency to adjust an original fire time for a next timer interrupt.

摘要： Exemplary embodiments of methods and apparatuses to manage a power of a data processing system are described. One or more constraint parameters of a system are monitored. The data processing system is forced into an idle state for a first portion of a time while allowed to operate for a second portion of the time based on the one or more constraint parameters, wherein the system is forced into the idle state in response to comparing a target idle time to an actual idle time. The target idle time of the system is determined, in one embodiment, based on the one or more constraint parameters. The actual idle time of the system may be monitored to take into account interrupts which disrupt an idle time and idle times resulting from no software instructions to execute. The system may be allowed to operate based on comparisons of the target idle time and the actual idle time.
