Hi all,
Update on this series:
- Use a RAM address of 64bits only on 64bits targets when Xen is enable.
- Add some comment on the memory registration done for Xen.
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.
Regards,
Anthony PERARD (3):
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.
cpu-common.h | 8 ++++++++
exec.c | 9 +++++----
vl.c | 14 ++++++++------
xen-all.c | 29 +++++++++++++++++++++--------
