[Qemu-devel] [PATCH V15 00/18] Xen device model support

[<anthony.perard@citrix.com>]

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

Hi all,

Here is an update on the series that add the support of a Xen HVM guest to
QEMU.

change v14-v15:
  - add a patch to not initialise vmport with Xen.

The change v13->v14:
  - Remove of ram_size parameter from pc_memory_init
  - set both below/above_4g_mem_size at the same place in the code.

Change v12->v13:
  - There are few changes in the xen init code. A xen_hvm_init function is new
    in this patch set and is call from xenfv:machine->init.
  -> So "-xen-create -M xenpv" will continue to work as before this patch
    series.
  - There is a new reset handler to set env->halted = 0 on the first vcpu.
  - One change have been made to pc_memory_init, the calculation of
    below/above_4g_mem_size have been moved to pc_init1. This is to remove a
    "random" "if (xen()) return;" in pc_memory_init.
  - xen_map_block is a new function to map RAMBlock that belong to a ROM/RAM of
    a device.
  - fix cpu_physical_memory_unmap with mapcache, Because qemu_get_ram_ptr can
    be called more than one time in cpu_physical_memory_map, qemu_put_ram_ptr
    need to be called the same amount of time.
  - Add some trace_* call.


This series depends on the series "Introduce "machine" QemuOpts".
