Subject: [PATCH 0/3] ftrace: Add timer-source of walltime for ftrace
Date: Tue, 25 Aug 2009 16:12:15 +0800 [thread overview]
Message-ID: <4A939CDF.2000407@cn.fujitsu.com> (raw)
In-Reply-To: <alpine.DEB.2.00.0908181454090.727@gandalf.stny.rr.com>
Hi,
I finished this patchset to enable ftrace display walltime.
We can get following output by using it:
# cd /mnt/debugfs/tracing/
# cat trace_clock
[local] global walltime
# echo sched_switch > current_tracer
# cat trace
# tracer: sched_switch
#
# TASK-PID CPU# TIMESTAMP FUNCTION

This patchset merged suggestion of Steven, Frederic and Kosaki-san on last RFC.
Thanks
