Well, you'd need the part of Jean's patches which adds the event to evlist:

AFAICT, you could apply patches 1-5 and replace 6 with yours. Now,
rasd.cfg has the mce:mce_record tracepoint which rasd opens but you
probably want to put a tracepoint which is much easier to exercise,
maybe some syscall or whatever.

I think that should do it but we won't know until we've tried it.

HTH and thanks a lot for doing this!
