Hi, I'm trying to investigate a problem under Linux 2.6.39.4 involving kworker threads and am pretty much stymied. I've tried enabling various events using --function and --probe and it's been very hit or miss. Very often, "lttng enable-event" comes back with nothing more specific than "bad ioctl", but every once in a while I'll find a symbol I can add a probe point for.
So: What does "--probe" mean? What does "--function" mean, and how does it differ from "--probe"? How do I determine what symbols are valid for each of these options? And, maybe as a worked example, how do I trace what work is being enqueued and run by the kworker threads? Thanks, Bill _______________________________________________ lttng-dev mailing list [email protected] http://lists.lttng.org/cgi-bin/mailman/listinfo/lttng-dev
