[PATCH v7 13/14] sched/topology: Make Energy Aware Scheduling depend on schedutil

2018-09-12 Thread Quentin Perret
Energy Aware Scheduling (EAS) is designed with the assumption that frequencies of CPUs follow their utilization value. When using a CPUFreq governor other than schedutil, the chances of this assumption being true are small, if any. When schedutil is being used, EAS' predictions are at least
