Hello all, I'm trying to get stack traces for a bunch of events using perf record and having trouble with them getting cut off. I'm using --callgraph dwarf, which helps a little, and I recompiled libc with --fno-omit-frame-pointer, which doesn't seem to have helped at all. Very often, the bottom of the stack is in libc, often __epoll_wait_nocancel. Stacks for sched:sched_switch events seem to be worse than cycles or sched:sched_wakeup events, but it isn't 100%. Is there anything else I could try?
Thanks, --Daniel Speyer -- To unsubscribe from this list: send the line "unsubscribe linux-perf-users" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
