[Xen-ia64-devel] [PATCH 0/7] memory map info

[Isaku Yamahata <yamahata@xxxxxxxxxxxxx>]

Hi.

This patch serires is mainly for fixing HVM domain save/restore
which Zhang reported.
The patch 7, add IA64_dom0VP_add_memdesc hypercall, is not for commit yet
because pv_ops balloon driver isn't supported on ia64 yet.

The reason why HVM domain save/restore is broken is as follows.
Tools stack (save or dump-core) is aware of the region which
is populated as RAM.
However the patch, 'Use main memory for video memory', move pages
from main mamory to 0xc0000000. So save or dump-core fails to
dump those pages. Then HVM domain restore fails.
This patch series (more precisly Patch 5/7) makes XENMEMadd_to_physmap
hypercall with XENMAPSPACE_mfn update the memory map info of a given
domain.
