Would you mind explaining why? it seems to me that rdtscll() here would be perfectly safe: the only case in which they wouldn't, is in a nested-vm environment running paravirt-linux with a paravirt tsc. In this case, it is quite likely that we'll want rdtscll *anyway*, instead of going to tsc directly. -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
