ABSTRACT:
A computer system that has multiple performance states periodically obtains utilization information for a plurality of tasks operating on the processor and determines processor utilization according to the utilization information for the plurality of tasks. The system compares the processor utilization to at least one threshold and selectively adjusts a current processor performance state to another performance state according to the comparison.
