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