摘要： A processing system may include a performance monitoring unit (PMU), a machine accessible medium, and a processor responsive to the PMU and the machine accessible medium. Instructions encoded in the machine accessible medium, when executed by the processor, may determine whether performance details for the processing system should be collected, based at least in part on a predetermined monitoring policy for the processing system. The instructions may generate performance data for the processing system, based at least in part on data obtained from the PMU. The instructions may determine whether the processing system should be reconfigured, based at least in part on the performance data and a power policy profile for the processing system. The instructions may automatically adjust power consumption of the processing system by using the PMU to reconfigure the processing system. Other embodiments are described and claimed.

摘要： A disclosed method involves initializing a performance profiler of a processing system. The performance profiler may include performance profile parameters for a power management policy for the processing system. The method also involves retrieving performance metrics for the processing system from a performance monitoring unit (PMU) of the processing system, in response to a determination that performance details should be collected. A current performance state of the processing system may be determined, based at least in part on the performance profile parameters and the performance metrics from the PMU. The current performance state may then be communicated to a policy manager of the processing system. Other embodiments are disclosed and claimed.
