Abstract
In one embodiment, processor includes a first core to execute instructions, and a power controller to control power consumption of the processor. The power controller may include a hardware performance state controller to control a performance state of the first core autonomously to an operating system, and calculate a target operating frequency for the performance state based at least in part on an energy performance preference hint received from the operating system. Other embodiments are described and claimed.
