* Remove ioemu-dir before replacing it with a symlink so that
switching between trees doesn't go wrong.
* Remove case-based arrangement for making XEN_ROOT absolute
and replace with $(abspath ...) since we depend on GNU make
anyway.
* `make clean' recurses into ioemu-dir

If the guest provides a suspend event channel through xenstore,
xc_save will use it in preference to the old xenstore-based method.
Xend is still informed when the domain has suspended so that it can
perform device migration in parallel with last-round migration.

This event channel will be notified when the domain transitions to the
suspended state, which can be much faster than raising VIRQ_DOM_EXC
and waiting for the notification to be propagated via xenstore.
No attempt is made here to prevent multiple subscribers (last one
wins), or to detect that the subscriber has gone away. Userspace tools
should take care.

and Device Specific Registers for pt device.
I implemented following Capability Structures and Device Specific
Registers.
* Configuration Header Type 0
-> emulation.
"emulation" does not mean no accessing real I/O device.
Access real I/O device, but guest value and real value
might be different.
* MSI Capability Structure
-> emulation.
Behavior is not changed from existed implementation in
pt-msi.c, although code is changed.
* MSI-X Capability Structure
-> emulation.
Behavior is not changed from existed implementation in
pt-msi.c, although code is changed.
* PCI Express Capability Structure
-> emulation.
* PCI Power Management Capability Structure
-> emulation.
* Vital Product Data Capability Structure
-> emulation.
Emulated register is only Next Capability Pointer
Register.
All other registers are passthrough.
* Vendor Specific Capability Structure
-> emulation
Emulated register is only Next Capability Pointer
Register.
All other registers are passthrough.
* Device Specific Register (exclude capability structures)
-> passthrough.
The device drivers in guest domain are allowed to access
Device Specific Register. So various I/O device will work.
I assigned following device to guest domain, and they worked fine.
- PCIe NIC (MSI)
- PCI NIC (MSI)
- UHCI (INTx interrupt)
- IDE Controller (INTx interrupt)

This provides support for building the new merged qemu from
qemu-xen.git, or from a local checkout.
The default is still to use the in-tree version, because the patchman
infrastructure for testing, and propagation from staging to
xen-unstable, needs a small amount of work to cope with git.

Rework blkdev_name_to_number to allow the tools to attach xvd disks
beyond xvdp.
1. Adds the handling for the /dev/xvd[q-z] and /dev/xvd[a-i][a-z]

2. Changes blkdev_name_to_number() to return a tuple of (xenbus,
devnum), and then deals with the resulting fallout.

Through recent additions to the rombios the code section of the post
function has filled up considerably. When I enable the BX_TCGBIOS
compile time option the BIOS crashes since the post section code
(starts at $e05b) spills over into the nmi entry point (starts at
$e2c3). as86 doesn't cause an error when building.

This patch is an extension for qemu-dm to enable emulation of generic
PCI devices. The information for the PCI devices can be passed by
command line parameter.
The command line parameter is "-pciemulation" followed by the
information which contains a label and hex value of the configuration
registers separated by ":".
The configuration registers for each PCI device are below.
vendorid
deviceid
command
status
revision
classcode
headertype
subvendorid
subsystemid
interruputline
interruptpin
This is an example of command line parameter.
