Just for completeness -- Linux already had a way to profile latencies since quite some time. It's little known unfortunately and doesn't work for modules since it's a special mode in the old non modular kernel profiler. You enable CONFIG_SCHEDSTATS and boot with profile=sleep and then you can use the readprofile command to read the data. Information can be reset with echo > /proc/profile There's also a profile=sched to profile the scheduler which works even without CONFIG_SCHEDSTATS Latencytop will be probably a little more user friendly though. -Andi -- 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/
