Consider, for instance, softirq_timer and softirq_sched. A\ntimer goes off in an ISR which schedules softirq_thread to run at RT50.\nThen the timer handler determines that it\u0027s time to smp-rebalance the\nsystem so it schedules softirq_sched to run. So we are in a situation\nwhere we have two RT50 tasks queued, and the system will go into\nrt-overload condition to request other CPUs for help.\n\nThis causes two problems in the current code:\n\n1) If a high-priority bound task and a low-priority unbounded task queue\n up behind the running task, we will fail to ever relocate the unbounded\n task because we terminate the search on the first unmovable task.\n\n2) We spend precious futile cycles in the fast-path trying to pull\n overloaded tasks over.

This, however, would yield this bandwidth:\n\n\tA \u003d 50%\n\tB \u003d 25%\n\tC \u003d 25%\n\nwhich is not the desired result.\n\nWhat\u0027s changing in the patch?\n\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\n\n\t- How cpu weights are calculated when CONFIF_FAIR_GROUP_SCHED is\n\t defined (see below)\n\t- API Change\n\t\t- Two tunables introduced in sysfs (under SCHED_DEBUG) to\n\t\t control the frequency at which the load balance monitor\n\t\t thread runs.\n\nThe basic change made in this patch is how cpu weight (rq-\u003eload.weight) is\ncalculated. Its now calculated as the summation of group weights on a cpu,\nrather than summation of task weights. Weight exerted by a group on a\ncpu is dependent on the shares allocated to it and also the number of\ntasks the group has on that cpu compared to the total number of\n(runnable) tasks the group has in the system.\n\nLet,\n\tW(K,i) \u003d Weight of group K on cpu i\n\tT(K,i) \u003d Task load present in group K\u0027s cfs_rq on cpu i\n\tT(K) \u003d Total task load of group K across various cpus\n\tS(K) \t\u003d Shares allocated to group K\n\tNRCPUS\t\u003d Number of online cpus in the scheduler domain to\n\t \t which group K is assigned.\n\nThen,\n\tW(K,i) \u003d S(K) * NRCPUS * T(K,i) / T(K)\n\nA load balance monitor thread is created at bootup, which periodically\nruns and adjusts group\u0027s weight on each cpu. To avoid its overhead, two\nmin/max tunables are introduced (under SCHED_DEBUG) to control the rate\nat which it runs.\n\nFixes from: Peter Zijlstra \u003ca.p.zijlstra@chello.nl\u003e\n\n- don\u0027t start the load_balance_monitor when there is only a single cpu.\n- rename the kthread because its currently longer than TASK_COMM_LEN\n\nSigned-off-by: Srivatsa Vaddagiri
