PROCHOT Demotion Algorithm

PROCHOT demotion algorithm is designed to improve system performance following multiple Platform PROCHOT consecutive assertions. During each PROCHOT assertion processor will eventually transition to the lowest P-State (Pn) supported by the processor IA cores and graphics cores (LFM). When detecting several PROCHOT consecutive assertions the processor will reduce the max frequency in order to reduce the PROCHOT assertions events. The processor will keep reducing the frequency until no consecutive assertions detected. The processor will raise the frequency if no consecutive PROCHOT assertion events will occur. PROCHOT demotion algorithm enabled only when the PROCHOT is configured as input.
