title: Kernel trace using Lttng
body: <p>I have been playing around with linux trace tools (Lttng, <a href="http://lttng.org/" rel="nofollow">http://lttng.org/</a>) for sometime now. Currently, I'm interpreting the trace using Eclipse with Lttng plug-in.  Although using this tool I could retrieve logs associated with system calls, context switches, I couldn't find a way to trace a particular event occurring at a specific location say an interrupt raised by a peripheral. I also tried my hand at KProbes for dynamic tracing but in vain. Any suggestions/guidance will be useful and highly appreciated.  </p>
