On AMD cpus, HVM S3 resume was hanging in the bios when trying
to load the x_firmware_waking_vector from absolute
address 0xEA01C (that is, a segment offset greater than 64kB).
This change also now uses 20-bits (instead of 16) from the FACS
standard firmware_waking_vector.

F10 to select boot device. This will be rarely used, and it is
possible to hit F10 before the message is displayed and the keypress
will still register. So in practice it is quite possibel to use this
boot feature reliably without needing a multi-second delay.

* Cleanly define a scratch area for temporary storage
* Raise Etherboot ROM out of the way of larger VGA BIOSes
Also detect virtual VGA adaptors more cleanly.

- add S3 package in ACPI DSDT table. Guest OS will get S3 value from
this package and write the value to PM1A control register to
trigger S3 suspend.
- Add S3 resume logic in rombios post code. the CMOS shutdown register
is used to indicate if this is a S3 resume.
- if it is s3 resume, rombios will get wakeup vector from ACPI FACS
table and jump to wakeup vector. Per ACPI spec, the wakeup vector
jumping must be the forms CS:IP, in which CS=3D(wakeup vector>>4)
IP=3D(wakeup vector)&0xF, for example, for vector=3D0x12345,
CS:IP=3D0x1234:0x5
Note: clobber_entry_point will clobber the post entry, which make S3
resume not work. We will directly jmp to POST Entry if it in S3
Resume path.

- Move MTRR MSR initialisation into hvmloader.
- Simplify initialisation logic by overlaying UC on default WB rather
than vice versa.
- Clean up hypervisor HVM MTRR/PAE code's interface with rest of
hypervisor.

Some versions of Windows 2000 only support no more than 15 cpus in
ACPI table, otherwise it will cause a BSOD
KMODE_EXCEPTION_NOT_HANDLED. This patch decrease the cpu count in the
ACPI DSDT to 15.

I ran into this when I was reviewing what was outstanding to get
NetWare to run fully virtualized.
The BIOS emulator code has the segment and offset backward in the
returned buffer for the int 13h, fn 48h BIOS call.

No need to generate the correct number dynamically since
present/not-present can be determined from the MADT. What *is*
required is that we have a Processor Object for every present
processor. We statically declare 16 Objects, which should be plenty
for now.

** Currently only 2 virtual hotplug pci slots(6~7) are created so more
than 2 vtd dev can't be hotplugged, but we can easily extend it in
future.
Three new commands are added:
"xm pci-list domid" show the current assigned vtd device, like:
VSlt domain bus slot func
0x6 0x0 0x02 0x00 0x0
"xm pci-detach" hot remove the specified vtd device by the virtual
slot, like:
xm pci-detach EdwinHVMDomainVtd 6
"xm pci-attach DomainID dom bus dev func [vslot]" hot add a new vtd
device in the vslot. If no vslot specified, a free slot will be picked
up. e.g. to insert '0000:03:00.0':
xm pci-attach EdwinHVMDomainVtd 0 3 0 0
** guest pci hotplug
linux: pls. use 2.6.X and enable ACPI PCI hotplug ( Bus options=> PCI
hotplug => ACPI PCI hotplug driver )
windows: 2000/xp/2003/vista are all okay

A new platform variable 'hpet' is added, which defaults to 0 for new
guests (that is, hpet disabled). Default is off (no hpet) because
hpet is currently less accurate in keeping time than PIT (because no
timer_mode adjustments).

This patch adds extboot to Xen. It should be pretty harmless as the
moment because it's never enabled. extboot allows arbitrary block
devices to be used to boot guests including SCSI and PV disks. I've
tested it with both Windows and Linux guests in QEMU.

The attached patch implements a mini BIOS menu for choosing a
non-default
boot device. When a guest starts it'll display
'Press F10 to select boot device'
And wait 3 seconds, before continuing with the normal boot device. If
they press the F10 key, a menu is shown allowing a choice between
floppy, harddisk, cdrom and network (PXE).
I can't take credit for this originally - Jeremy Katz wrote it for
KVM, I merely re-diffed the patch to work against Xen's QEMU/BIOS code
tree. It has been tested in Fedora successfully against 3.1.x and 3.2.x
