[PATCH v6 10/14] sched/cpufreq: Refactor the utilization aggregation method

2018-08-20 Thread Quentin Perret
Schedutil aggregates the PELT signals of CFS, RT, DL and IRQ in order to decide which frequency to request. Energy Aware Scheduling (EAS) needs to be able to predict those requests to assess the energy impact of scheduling decisions. However, the PELT signals aggregation is only done in schedutil f
