What did I miss? :) I don't think this is a question about speed. Ard doesn't like the spec. You like the feature more than you dislike the spec. Apparently that means there's a disagreement. As I mentioned earlier, I'd encourage you to send a patch to the ACPI people and let them decide. If that gets in, then I'm fine with modifying vmgenid to meet the spec and take advantage of the change you'll be making to the ACPI code. If it is rejected by the ACPI people, and consequently Linux isn't able to match on _CID, then I guess we'll have the next best thing, which is "well, it still works on QEMU." Hopefully you'll convince them. Feel free to CC me on that patch. Jason
