I agree with you that customized ACPI tables is needed for IO domains. However I prefer read-only mapping of these pages to domain for domain0 I haven't implemented read-only grant page mapping yet. (I plan to do it after the mergeing effort) Once it is implemented, it can be used for read only mapping of ACPI-related pages. > * We must be sure that only physical memory < 4GB is mapped below 4 GB in > domains.

Does alloc_domheap_page() handles it? #define alloc_domheap_page(d) (alloc_domheap_pages(d,0,0)) It passes flags = 0. Or do you mention about other things? -- yamahata _______________________________________________ Xen-ia64-devel mailing list Xen-ia64-devel@lists.xensource.com http://lists.xensource.com/xen-ia64-devel
