Hello, right now I am reading the LTTng documentation and I am at the point with the "tutorial" for adding a tracepoint to the usb_probe_device(). I updated the files as instructed, rebuilt the kernel and bootet it, but the "/sys/kernel/debug/tracing/events/hello" directory wasnt created. It exists up to the debug directory, but the directory itself is empty. What could have gone wrong? Is this directory necessary? I still followed the other instructions and I was able to trace the USB event but I am curios about the directory. Furthermore, I am planning to instrument an RTAI kernel (for my Bachelorthesis), so I can trace it with LTTng. Is it even possible with these methods?
Thank you for your time! PS: I am using an RTAI patched 2.6.38.8 linux kernel with debian _______________________________________________ lttng-dev mailing list [email protected] http://lists.lttng.org/cgi-bin/mailman/listinfo/lttng-dev
