If we want to trace "sched:sched_switch" to trace sched_switch func, We may utilize event option.(e.g: trace-cmd list -e | grep sched) This patch is based on Linux-3.3.rc2-SMP-PREEMPT Link: http://lkml.kernel.org/r/1328695537-15081-1-git-send-email-geunsik.lim@gmail.com Cc: Randy Dunlap <rdunlap@...otime.net> Signed-off-by: Geunsik Lim <geunsik.lim@...sung.com> Signed-off-by: Steven Rostedt <rostedt@...dmis.org> --- kernel/trace/trace.c | 6 +++--- 1 files changed, 3 insertions(+), 3 deletions(-) diff --git a/kernel/trace/trace.c b/kernel/trace/trace.c index a3f1bc5..10d5503 100644 --- a/kernel/trace/trace.c +++ b/kernel/trace/trace.c @@ -2764,12 +2764,12 @@ static const char readme_msg[] = "tracing mini-HOWTO:\n\n" "# mount -t debugfs nodev /sys/kernel/debug\n\n" "# cat /sys/kernel/debug/tracing/available_tracers\n" - "wakeup preemptirqsoff preemptoff irqsoff function sched_switch nop\n\n" + "wakeup wakeup_rt preemptirqsoff preemptoff irqsoff function nop\n\n" "# cat /sys/kernel/debug/tracing/current_tracer\n" "nop\n" - "# echo sched_switch > /sys/kernel/debug/tracing/current_tracer\n" + "# echo wakeup > /sys/kernel/debug/tracing/current_tracer\n" "# cat /sys/kernel/debug/tracing/current_tracer\n" - "sched_switch\n" + "wakeup\n" "# cat /sys/kernel/debug/tracing/trace_options\n" "noprint-parent nosym-offset nosym-addr noverbose\n" "# echo print-parent > /sys/kernel/debug/tracing/trace_options\n" -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
