I dont think I am handling that case well (yet), primarily because usage of remaining tasks (which are not in cpuset "all", "mikeg" & "root") is not accounted/controlled. Note that those remaining tasks will be running on one of the CPUs assigned to "all". What needs to happen is those remaining tasks need to be moved to a separate group (and a runqueue), being given some left-over CPU quota (which is left over from assignment of quota to mikeg and root), which is not handled in the patches (yet). One of the reason why I havent handled it yet is that there is no easy way to retrieve list of tasks attached to a cpuset. Can you try assigning (NUM_CPUS-1) cpus to "all" and give it a shot? Essentially you need to ensure that only tasks chosen by you are running in cpus given to "all" and other child-cpusets under it. -- Regards, vatsa - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/ | ||||||||||||
