[PATCH] sched/fair: Speed-up energy-aware wake-ups

2019-09-12 Thread Quentin Perret
From: Quentin Perret EAS computes the energy impact of migrating a waking task when deciding on which CPU it should run. However, the current approach is known to have a high algorithmic complexity, which can result in prohibitively high wake-up latencies on systems with complex energy models,
