Well, you'd need the part of Jean's patches which adds the event to evlist: https://lkml.kernel.org/r/1412933690-25576-1-git-send-email-jean.pihet@linaro.org 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! -- Regards/Gruss, Boris. Sent from a fat crate under my desk.
