Only lightly tested with a Linux HVM guest PXE boot.
Accept the defaults for the config options. Many of them are not
relevant to Xen but this matches what others (at least the Debian
SeaBIOS packages and the binary shipped by Qemu) are doing. The
Debian Xen packages are built against Debian's SeaBIOS package so
there is value in being similar.

Microsoft have now published their VM generation ID specification at
https://www.microsoft.com/en-us/download/details.aspx?id=30707.
It differs from the original specification upon which I based my
implementation in several key areas. Particularly, it is no longer
an incrementing 64-bit counter and so this patch is to remove
the incr_generationid field from the build_info and also disable the
ACPI device before 4.2 is released.
I will follow up with further patches to implement the VM generation
ID to the new specification.

Currently qemu-xen will be compiled with CFLAGS only if CFLAGS was
already in the environment during make invocation. If CFLAGS is in
environment then make will append all of the various flags specified in
xen Makefiles to this environment variable, which is then used in qemu
configure. Since qemu-xen is not ready for compiler flags like
"-std=gnu99" compilation will fail. If CFLAGS is not in environment,
then configure will use just its own "-O2 -g" because make does not
export its own CFLAGS variable.
>From a distro perspective, it is required to build libraries and
binaries with certain global cflags (arbitrary gcc options). Up to the
point when qemu-xen was imported it worked as expected by exporting
CFLAGS before 'make tools'. Now qemu-upstream reuses these CFLAGS, but
it cant deal with the result.
This patch extends the tools Makefiles so that three new environment
variables are recognized:
EXTRA_CFLAGS_XEN_TOOLS= specifies CFLAGS for the tools build.
EXTRA_CFLAGS_QEMU_TRADITIONAL= specifies CFLAGS for old qemu.
EXTRA_CFLAGS_QEMU_XEN= specifies CFLAGS for new qemu.
Special care needs to be taken in tools/firmware because the resulting
binaries are not linked with the hosts runtime libraries. These binaries
run in guest context. To avoid build errors from gcc options like
-fstack-protector, reuse existing practice to unset the new
EXTRA_CFLAGS_XEN_TOOLS for the firmware dirs.
The new feature can be used like this in a rpm xen.spec file:
export EXTRA_CFLAGS_XEN_TOOLS="${RPM_OPT_FLAGS}"
export EXTRA_CFLAGS_QEMU_TRADITIONAL="${RPM_OPT_FLAGS}"
export EXTRA_CFLAGS_QEMU_XEN="${RPM_OPT_FLAGS}"
./configure \
--libdir=%{_libdir} \
--prefix=/usr

This patch introduces configuration options allowing to built either a
rombios only or a seabios only hvmloader.
Building option ROMs like vgabios or etherboot is only enabled for a
rombios hvmloader, since SeaBIOS takes care or extracting option ROMs
itself from the PCI devices (these option ROMs are provided by the
device model and do not need to be built in hvmloader).
The Makefile in tools/firmware/ now only checks for bcc if rombios is
enabled.
These two configuration options are left on by default to remain
compatible.

The Intel GPU uses a two pages NVS region called OpRegion.
In order to get full support for the driver in the guest
we need to map this region.
This patch reserves 2 pages on the top of the memory in the
reserved area and mark this region as NVS in the e820. Then
we write the address to the config space (offset 0xfc) so the
device model can map the OpRegion at this address in the guest.

Change the way we relocate the memory page if they overlap with pci
hole. Use new map space (XENMAPSPACE_gmfn_range) to move the loop
into xen.
This code usually get triggered when a device is pass through to a
guest and the PCI hole has to be extended to have enough room to map
the device BARs. The PCI hole will starts lower and it might overlap
with some RAM that has been alocated for the guest. That usually
happen if the guest has more than 4G of RAM. We have to relocate
those pages in high mem otherwise they won't be accessible.
