Abstract
In one embodiment, a processor includes a plurality of cores to execute instructions, a first identification register having a first field to store a feedback indicator to indicate to an operating system (OS) that the processor is to provide hardware feedback information to the OS dynamically and a power controller coupled to the plurality of cores. The power controller may include a feedback control circuit to dynamically determine the hardware feedback information for at least one of the plurality of cores and inform the OS of an update to the hardware feedback information. Other embodiments are described and claimed.
