Hi all,

I am writing to kindly ask one question: is there any tracing
mechanism in Linux kernel that can trace all the executed instructions
of a user process? If this user process is run on different
processors, traces of this process on different processors should be
also recorded.

Any comment is welcome.

My best regards to you.
