(this flag is a bit #1 == 2) cat /proc/sys/kernel/sched_domain/cpu0/domain0/flags ? it can be changed with "echo new_value > ..." does a change of it make any difference? moreover, /proc/sys/kernel/sched_domain/cpu1/domain0/newidle_idx seems to be responsible for a source of the load for calculating the busiest group. e.g. with newidle_idx == 0, the current load on the queue is used instead of cpu_load[]. > > Thanks, > --Micah > -- Best regards, Dmitry Adamushko - 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/
