ABSTRACT:
A power level monitor and performance tracking tool are provided for correlating system performance with processor management events. When power management requires a change to the state of a microprocessor, software will be notified. Multiple layers of software may be notified, including a firmware level, an operating system, as well as applications. The performance tracking tool tracks the times of the power management events as well as their impact to the microprocessor performance. The performance tracking tool may then display or record the state changes to processor performance. These changes may be correlated against other system events to aid in determining system performance problems with respect to power management.
