Very nice Namhyung, thanks for doing this. I did a quick run through of the patches and I have no complaints about them. I'm not sure how the others will feel about it. Also, have you given thought on how to execute both ftrace and the pmu counters? That is, to get a way to interleave the data? I added a 'perf' clock to ftrace. I didn't see that being checked, although I didn't look too hard. If possible, you can use that, as well as the multi-buffers that are coming in 3.10. I would also like to add a system call to allow you to get to the ftrace data without the need for debugfs. I'm not sure if we should piggy back on the perf system call, or add a new one. I'm thinking we should add a new one so that it doesn't get too confusing.
