The initial idea was to disable load balance between CPUs and then do this. So, that new timers and workqueues from other CPUs would never get queued on this CPU.. But I think we can just modify get_nohz_timer_target() for making sure this for timers.. > Seems like the proposal discussed is to support setting > cpu affinity for workqueues through sysfs.

That was another thread just for workqueues, but this one is about migrating everything else as well.. Probably some more additions apart from timers/ hrtimers/wqs in future. So, for us it is still required :) -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
