Abstract:
Systems and methods are disclosed for power management in information handling systems using processor performance data to validate changes to processor performance states. Processor utilization data and processor performance data is obtained during system operation. The processor utilization data is analyzed to determine a desired performance state for the processor. Before setting the actual performance state of the processor to this desired performance state, however, processor performance data is analyzed to determine if prior changes to the performance state have been effective. The performance state of the processor is then changed are maintained based upon this additional performance verification analysis.
