[Xen-devel] [PATCH v2 00/18] xen: add pvh guest support

[Juergen Gross <jgross@xxxxxxxx>]

This patch series adds support for booting Linux as PVH guest.

Similar to i386/xen and x86_64/xen platforms the new i386/xenpvh
platform grub is booted as a standalone image directly by Xen.

For booting Linux kernel it is using the standard linux kernel
loader. The only modification of the linux loader is to pass the
ACPI RSDP address via boot parameters to the kernel, as that table
might not be located at the usual physical address just below 1MB.

As the related Linux kernel patches are not yet accepted please
wait for this to happen before applying the series. This Linux kernel
series is available under:

Changes in V2:
- extend linux boot protocol version 2.14 to report back the protocol
  version supported by grub2 (needed as there are grub2 downstream
  variants in some distros which clobber data after the setup_header)
- split former patch 4 into 10 patches
- fix memmap handling for >4GB of memory
- added new patch from Hans (thanks for that one)
- addressed most of Daniel's comments (see individual patches)

Hans van Kranenburg (1):
  grub-module-verifier: Ignore all_video for xenpvh

Juergen Gross (17):
  xen: add some xen headers
  loader/linux: support passing rsdp address via boot params
  xen: carve out grant tab initialization into dedicated function
  xen: prepare common code for Xen PVH support
  xen: add some dummy headers for PVH mode
  xen: rearrange xen/init.c to prepare it for Xen PVH mode
  xen: add PVH specific defines to offset.h
  xen: add basic hooks for PVH in current code
  xen: add PVH boot entry code
  xen: setup hypercall page for PVH
  xen: get memory map from hypervisor for PVH
  xen: setup Xen specific data for PVH
  xen: init memory regions for PVH
  xenpvh: add build runes for grub-core
  xenpvh: support building a standalone image
  xenpvh: support grub-install for xenpvh
  xenpvh: add support to configure
