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 trace on different CPU (the system has 4) but not for all 4, just 1 cpu 3. no recorded session span more than 1 second though I would run sleep (i.e., 10s) between "start" and "stop" This leads me to believe LTTng might be dependent on something in the system that isn't present. This is a customized kernel of a client. It has all required configs. If there is a trigger mechanism after running "lttng start", what would it be? It seems it grabs items initially then doesn't continue. I read in one of the papers that LTTng is architecture dependent. Any help is appreciated. Thanks, Mike
