[Xen-ia64-devel] [Patch] Add more dom0 operations

["Tian, Kevin" <kevin.tian@xxxxxxxxx>]

Hi, Dan,
        This patch adds more dom0 operations support, with following
notes:

1. Each architecture may have its own set of operations, so a new
dom0_ops_ia64.h is created temporarily. Later cleaner re-org should be
made. :)

2. Add a new hypercall DOM0_GET_SECTIONINFO, to get memory hole, I/O
port, etc in guest physical address space. This is necessary for CP and
DM to create foreign map, especially for VTI domain. As Ian said before,
para-virtualized x86 guest is configured with contiguous physical memory
without any hole. Though currently not required for para, keeping it
there at least provides a possibility for other variations. :)

3. I'm not sure why latest check-in about DOM0_GETMEMLIST differs much
from x86 behavior. Could you explain a bit about that? IMHO, XEN/IA64
can have same syntax as x86 easily, since page allocator already
aggregates available pages list under domain struct. So a different
version is provided enclosed by CONFIG_VTI. If we can set on the same
page later, it may be extracted out then.

Signed-off-by   Kevin Tian <Kevin.tian@xxxxxxxxx>

Thanks,
Kevin
