  • Controlling power state demotion in a processor
    Patent number: 11216276
    Abstract: In an embodiment, a processor for demotion includes a plurality of cores to execute instructions and a demotion control circuit. The demotion control circuit is to: for each core of the plurality of cores, determine an average count of power state break events in the core; determine a sum of the average counts of the plurality of cores; determine whether the average count of a first core exceeds a first demotion threshold; determine whether the sum of the average counts of the plurality of cores exceeds a second demotion threshold; and in response to a determination that the average count of the first core exceeds the first demotion threshold and the sum of the average counts exceeds the second demotion threshold, perform a power state demotion of the first core. Other embodiments are described and claimed.
