then I don't understand why you advocate ACPI here.

what we should have is portable power management API, which should
be very MI (this can be very independent from ACPI - I have no
concrete picture yet). underneath we can have ACPI, APM, whatever
you name it. for hpcmips case, you don't need to emulate ACPI.
why do we need to implement (1) ACPI parser, and (2) ACPI pseudo
instructions for hpcmips which can be cryptic, for hpcmips case?
