[Xen-devel] [PATCH 0/5] Enable QEMU to handle more than 2GB with Xen.

Hi all,

Xen is not limited by the QEMU's virtual address space for the allocation of
the guest RAM. So even with a QEMU 32bits, a Xen guest can have more than 4 GB
of RAM.

With this serie, we will be able to run a guest with more than 4GB. The main
point is to change ram_addr_t from ulong to uin64 when QEMU is configure with
Xen. The second point is better register the memory in QEMU.


Anthony PERARD (5):
  xen: Fix xen_enabled().
  exec.c: Use ram_addr_t in cpu_physical_memory_rw(...).
  cpu-common: Have a ram_addr_t of uint64 with Xen.
  xen: Fix the memory registration to reflect of what is done by Xen.
  vl.c: Check the asked ram_size later.
