[RFC/RFT] [PATCH 00/10] Intel_pstate: HWP Dynamic performance boost

2018-05-15 Thread Srinivas Pandruvada
This series tries to address some concern in performance particularly with IO workloads (Reported by Mel Gorman), when HWP is using intel_pstate powersave policy. Background HWP performance can be controlled by user space using sysfs interface for max/min frequency limits and energy performance pr
