Ah indeed. My Core2Quad didn't have an L3 afaik (its sitting around without a PSU atm so checking gets a little hard) so the LLC level was the L2 and all worked out right (it also not having SMT helped of course). But if there was a Xeon chip that did add a package L3 then yes, all this would become more interesting still. We'd need to extend the scheduler topology a bit as well, I don't think it can currently handle this well. So I guess we get to do some work for steamroller. -- 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/
