From: Anthony PERARD <anthony.perard@xxxxxxxxxx> This patches are for Xen-unstable and Qemu-DM. With the integration of Xen into QEMU, we would like to minimise the change and use the ACPI implementation of QEMU. So there are some change to make on the firmware to match the QEMU's BIOS. Some IO Ports are different and the sleep state values are different. Change with the v2->v3: Xen will register the old ioport by default and switch to the new ioport if the HVM_PARAM_ACPI_NEW_IOPORT is set. So, this series come with a new function, unregister_io_handler, and a new HVM_PARAM. Change v1->v2: This time, both old and new ioport are handled. In QEMU-Xen, the choice between one or the other is made when a saved state is restored. In Xen, both ioports are registered.
