[RFC PATCH v3 5/6] sched/cpufreq: Boost schedutil frequency ramp up

2019-10-11 Thread Douglas RAILLARD
In some situations, it can be interesting to spend temporarily more power if that can give a useful frequency boost. Use the new sugov_cpu_ramp_boost() function to drive an energy-aware boost, on top of the minimal required frequency. As that boost number is not accurate (and cannot be without a
