I think Cx could be added relatively easily as a software event, but frequency doesn't fit very well into the perf counting model, as it's really sampling. -Andi -- 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/
