[Qemu-devel] [PATCH RFC V3 00/12] xen device model support

[anthony.perard@citrix.com]

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

Hi all,
this is the third 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 finally removed the special target for Xen and use the i386 target.

- we removed xenstore management, we have only one call to xenstore to
  tell the device model state ("running").

- we integrated MapCache to RAMBlock infrastructure. This come with a new fonction
  qemu_ram_ptr_unlock because MapCache need to know if he can unmap a block.

- we removed dynamic check of Xen in get_irq_slot and set_irq, in piix_pci,
  and used Xen function with pci_bus_irqs.

- we converted the GPE of the Xen ACPI to VMSTATE.


Anthony PERARD (12):
  xen: Support new libxc calls from xen unstable.
  xen: Add xen_machine_fv
  xen: Introduce --enable-xen command options.
  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
  Intruduce 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
