[Qemu-devel] [PATCH RFC V4 00/14] xen device model support

[anthony.perard@citrix.com]

From: Anthony PERARD <anthony.perard@citrix.com>

Hi all,
this is the fourth version of the patch series that adds xen device
model support in qemu.

This is the list of changes we made on top of the last version:

- we addressed the code style change requests;

- we have split mapcache in two file xen-mapcache.c and xen-mapcache-stub.c
  with check in configure to use one or the other;

- we have fixed the compilation issue with user-only target and with older Xen
  release (3.3.0, 3.4.0 and 4.0.1), this come with more check in the configure script;

- we have replaced -enable-xen by a more generic options, 
  so we introduce -accel options (use for kvm and xen).

For the next time we have to remove the Xen specific ACPI Implementation.

Anthony PERARD (14):
  xen: Replace some tab-indents with spaces (clean-up).
  xen: Support new libxc calls from xen unstable.
  xen: Add xen_machine_fv
  Introduce -accel command option.
  xen: Add xen in -accel option.
  xen: Add the Xen platform pci device
  piix_pci: Introduces Xen specific call for irq.
  xen: add a 8259 Interrupt Controller
  xen: Introduce the Xen mapcache
  Introduce qemu_ram_ptr_unlock.
  vl.c: Introduce getter for shutdown_requested and reset_requested.
  xen: Initialize event channels and io rings
  xen: Set running state in xenstore.
  xen: Add a Xen specific ACPI Implementation to target-xen
