    SubjectRe: ACPI request/release generic address
    -----BEGIN PGP SIGNED MESSAGE-----
    Hash: SHA1

    It an acpi_generic_address structure defined in include/acpi/actbl2.h.
    It's an address that can be in memory, I/O, or PCI configuration space.

    The definition is at http://www.microsoft.com/hwdev/tech/onnow/LF-ACPI.asp

    |Can you define a generic address?
    |
    |IIRC, ACPI needs some work in this area.
    |
    |If the "generic address" is host RAM, that's easy.
    |If the generic address is PIO address, that's mostly easy.
    |If the generic address is MMIO address, that takes a bit of care with
    |mapping, and I'm not sure ACPI gets it right in these cases.
