Well, I wasn't thinking *that* early actually. So, I'm trying to enable tracing at some point after jump_labels (could be near perf_event_init). Right now, the static ring buffer part is done and I'm having some problems copying this ring buffer into the *real* one. Mind giving me another hint? Thanks a lot for your help so far, Ezequiel. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
