So if I understand this correctly, you set all possible CPUs on active
and available. What exactly happens if one of these is not usable?
I know that Darwin broke on the _PR description quite badly, as it
just allocates possible execution engines using the ACPI Processor
specification and I do not know what happens if the engine is not
available.
I have to admit that I have not tested it as I do not have the time to
do so though, so maybe it works.
