FYI, I've also got another driver in progress that will need domains
assigned outside the ACPI range, so it's not just limited to VMD.

Hi John,
please fix your quoting of the previous mails, thanks!
What ACPI defines does not matter at all. Linux uses 32-bit domains

(e.g. VMD).
You've also not demontrated any issue with any Linux driver yet.

Which of the many nvidia drivers in the tree? Just fix it instead of

instance? Why do drivers ca
