[PATCH V4 38/38] x86/intel_rdt: Limit C-states dynamically when pseudo-locking active

2018-05-22 Thread Reinette Chatre
Deeper C-states impact cache content through shrinking of the cache or flushing entire cache to memory before reducing power to the cache. Deeper C-states will thus negatively impact the pseudo-locked regions. To avoid impacting pseudo-locked regions C-states are limited on pseudo-locked region
