Re: [Xen-ia64-devel] [PATCH] SMP_HOST: Alloc vhpt from domheap

[Isaku Yamahata <yamahata@xxxxxxxxxxxxx>]

Hi Anthony.

struct domain->max_pages is used for two purposes currently.
a) to account pages allocated for a domain.
   (by xen/common/page_alloc.c)
b) maximal pseudo physical address.
   (e.g. lookup_domain_mpa() in xen/arch/ia64/domain.c and others)

This patch breaks b). Somethings needs to be adjusted.
Maybe it is needed to add a new member to struct arch_domain for b)
and to compensate max_pages at domain construction.


How do you think about accounting pages which is used
for struct arch_domain->mm?
Please see pgtable_quick_list_alloc() in xen/arch/ia64/xen/xenmis.c.

Thanks.
