Hi, Dan,
Attached is the updated version to dom0_ops.c. After some
discussion with Ian, we decided to remove newly added hypercall and
instead turn to other means in user application level. Then rest stuff
is all IA64 specific without any touch to common code. Please apply.
Signed-off-by Kevin Tian <Kevin.tian@xxxxxxxxx>
Thanks,
Kevin

>> 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. :)
