Date: Wed, 8 Feb 2012 19:05:36 +0900 Message-Id: <1328695537-15081-1-git-send-email-geunsik.lim@gmail.com> X-Mailer: git-send-email 1.7.8.1 Sender: linux-kernel-owner@vger.kernel.org List-ID: X-Mailing-List: linux-kernel@vger.kernel.org Content-Length: 1694 Lines: 41 From: Geunsik Lim Actually, sched_switch function tracer is merged into wakeup/wakeup_rt Update 'mini-HOWTO' for ftrace(Kernel function tracer). 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 Signed-off-by: Geunsik Lim --- 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" -- 1.7.8.1 -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
