[lttng-dev] Strange result from LTTng porting to ARM

2014-11-12 Thread J Lin
Hello, I've recently ported LTTng to ARM and I can't seem to understand what is going wrong with my results. I ran a typical session with lttng enable-event -k -a for test. Here are the observations: 1. only lttng_xxx (e.g, lttng_statedump_interrupts) are recorded 2. different sessions yield

In order to correctly handle the use-case where events are enabled _after_ trace is started, and _after_ applications are already being traced, the event should be created in a disabled state, so that it does not trace events until its filter is attached. This fix needs to be done both in
