Abstract:
In some embodiments, the invention involves modification of the processor utilization calculations that are used by operating system power management services to improve processor efficiency. An embodiment of the present invention is a system and method relating to power management policies under operating system control. In at least one embodiment, the present invention is intended to modify the processor utilization evaluation process so that C-state transition time and/or unhalted reference cycles are included in the calculation. Other embodiments are described and claimed.
