Summary:A mechanism for P-state feedback to operating system (OS) with hardware coordination is described herein. In one embodiment, an example of a process includes, but is not limited to, receiving data from a processor representing an average performance over a previous period of time, and determining a performance state (P-state) for a next period of time based in part on the data representing the average performance over the previous period of time. Other methods and apparatuses are also described.
