Thanks for the per-entity tracking feature, we could know the details of each task by its help. This patch add its trace support, so that we could quickly know the system status in a large time scale, like now we may get each runqueue's usage ratio by:
cfs_rq's usage ratio = cfs_rq->runnable_load_avg/cfs_rq->load.weight Lei Wen (2): sched: add trace events for task and rq usage tracking sched: update cfs_rq weight earlier in enqueue_entity include/trace/events/sched.h | 73 ++++++++++++++++++++++++++++++++++++++++++ kernel/sched/fair.c | 31 ++++++++++++++++-- 2 files changed, 101 insertions(+), 3 deletions(-) -- 1.7.10.4 -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
