[lttng-dev] Adding kernel events

[Francis Deslauriers]

Hi Eric,

You have to define the LTTng probe in lttng-modules to hook on your custom
kernel tracepoint.
Have a look this commit where a new probe was added:
https://github.com/lttng/lttng-modules/commit/2ca394649a5fb4135bfbe541f090b06ef933a63b

Cheers!
Francis
