  • Thread-topic: [Xen-devel] [PATCH]hvm guest ACPI dynamic initialization

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
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.
