| |
This is the -v3 of the load balancing patches that makes nohz idle load balancing more scalabale. While the last 2 in the series are not directly related to nohz, I clubbed them as part of this series as I noticed them while I was working in this area and they helped the context switch intensive workloads improve on the 8-socket system.
First RFC version of this can be found at https://lkml.org/lkml/2011/11/1/368
Second version of this can be found at https://lkml.org/lkml/2011/11/18/518
changes from v2: a. Make the changelogs more descriptive. b. nr_busy_cpus in the sched_group_power is updated when entering idle irrespective of whether the tick is stopped or not. c. kick the idle load balancer for the groups sharing package resources and having more than one cpu busy. d. Incroporate Mike's patch for enhancing ttwu_feature instead of disabling the feature by default.
thanks, suresh
