Attached please see the hvm guest ACPI dynamic initialization update: 1. Adding dynamic USB bridge number..., so ACPI FADT table's ACPI HW register base pointer will no longer need to be changed. 2. No need to have USB support (USB=1 and usbdevice='device' ) switches in guest configuration to enable proper ACPI support. 3. ACPI PCI bridge will be init only on acpi=1 is set in guest configuration. 4. Minor issue is fixed in PIC mode _PRT table for PCI device 4( we don't have the such a device yet, fix it now for the future blow up). 5. The patch is tested on acpi=0/1;usb=0/1, smp/up Linux guest, Windows XP/2003 installation/boot, those all 16 combination cases. Signed-off-by: Winston Wang <winston.l.wang@xxxxxxxxx>
