6 This document only discusses CPU bandwidth control for SCHED_NORMAL.
9 CFS bandwidth control is a CONFIG_FAIR_GROUP_SCHED extension which allows the
10 specification of the maximum CPU bandwidth available to a group or hierarchy.
12 The bandwidth allowed for a group is specified using a quota and period. Within
21 cfs_quota units at each period boundary. As threads consume this bandwidth it
