Will try that.
I'm afraid not, per-task profiling with uncore doesn't really make that much sense. For IBS it does. We can't share a context with different PMUs, that'll totally mess up the event scheduling. We'll have to grow perf_event_task_context with an extra context and have IBS use that. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
