Hi All,

I would like to know if there is anyway to profile thread running time in linux kernel? If there is already some method for it, please share. Otherwise, let me know where to start looking

perf or oprofile should do the job. So far I only used perf to profile a driver so far. Be aware that you have to enable the profiling options when compiling your kernel. can you share a good tutorial or starting point to understand and use these tools?

Google is your friend, I had some success with following instructions a bloke called Brendan Gregg, who seems to be a profiling guru, wrote: http://www.brendangregg.com/linuxperf.html
