We still have quite a few letters in the Latin alphabet :) I assume any CPU with TSX will have something like that. PMU is model specific, but it's obviously something that is needed. So I wouldn't really call it HSW specific. Something like this will be likely in many Intel CPUs going forward. Also I don't know for sure but it wouldn't surprise me if the other CPUs with transactions (BG etc.) have something similar. > > Maybe we can allow some configuration on the userspace side that would > allow each individual user to be lazy and create shortcuts or aliasses > of some sort ? That would likely be a logistical nightmare. You could never send a measurement script to someone else. -Andi -- a...@linux.intel.com -- Speaking for myself only. -- 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/
