[PATCH v7 11/15] sched/core: uclamp: Extend CPU's cgroup controller

2019-02-08 Thread Patrick Bellasi
The cgroup CPU bandwidth controller allows to assign a specified (maximum) bandwidth to the tasks of a group. However this bandwidth is defined and enforced only on a temporal base, without considering the actual frequency a CPU is running on. Thus, the amount of computation completed by a task
