perf stat -a / record -a / top will work. The case it doesn't fix is per thread when the other sibling is not running a counter. Essentially with the patch you may still get under-counting on these specific events if they run per thread (or are really unlucky in multiplexing), but never over-counting on anything. In the past Ingo's guidance was to focus on the most common use cases, which I think this patch does. It would be possible to fix the per thread mode too, but it would need quite a bit of new infrastructure and I have doubts that's worth it. -Andi -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
