[Xen-devel] RE: Windows XP ACPI Installation

["Guy Zana" <guy@xxxxxxxxxxxx>]

Sorry, I accidently casted esi to uint8_t,
The value supposed to be 0xf7e70d58.

The PCI bars btw looks like this:

"""
(XEN) HVM4: pci dev 00:01:1 bar 20 size 00000010: 0000c001
(XEN) HVM4: pci dev 00:01:2 INTA->IRQ7
(XEN) HVM4: pci dev 00:02:0 bar 10 size 02000000: c0000008
(XEN) HVM4: pci dev 00:02:0 bar 14 size 00001000: b0000000
(XEN) HVM4: pci dev 00:03:0 bar 10 size 00000100: 0000c101
(XEN) HVM4: pci dev 00:03:0 bar 14 size 00000100: b0001000
(XEN) HVM4: pci dev 00:03:0 INTA->IRQ11
"""

I seperated non-prefetchable and prefetchable memory to two different address 
space:
/* 
    MMIO space looks like this:
        Non prefetchable mmio   0xB0000000 - 0xC0000000
        Prefectchable mmio      0xC0000000 - End
*/

Thanks,
Guy.
