I think PERFCOUNTER is your friend.

CONFIG_LOCK_PROFILE and xen-lockprof on tools side?

Not sure it is still working, though. Its about 9 years since I wrote
and used it.
It does work. I've used it recently for this theme.
But it gave me unclear results, I did not match them with what I got from xentrace and rough lauterbach traces.

Can you expand it? What are the differences between the 3?

Cheers,
