Hi all, This series is supposed to optimize the kernel/sched/clock.c and x86 sched_clock() implementations.
So far its only been boot tested. So no clue if it really makes the thing faster, but it does remove the need to disable IRQs. I'm hoping Eliezer will test this with his benchmark where he could measure a performance regression between using sched_clock() and local_clock(). It looks like ia64, the only other CONFIG_HAVE_UNSTABLE_SCHED_CLOCK user, already matches the new expectations -- mostly not requiring IRQs disabled for calling sched_clock(). -- 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/
