Hi, I'm trying to trace all lock operations in the kernel for a project which involves deciding dependencies between tasks. I'm using lttng for the tracing and was expecting to see a huge amount of trace events, but I see none. So obviously I have configured something wrong.
The question is what kernel configs are needed to trace lockdep lock operations? And do I need any configurations when starting the tracing? I use ltt-armall with the -l option, I have the module lockdep_trace inserted (any module parameters?). I have installed lttng using the ubuntu packages available in ppa. I have verified that all the markers under lockdep in debugfs are enabled, i.e. return 1. Other markers produce traces.
