Two possible problems (we may fix them later):
* should ACPI be copied instead of mapped ?
At least some ACPI tables must be duplicated to other IO domains.
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. This seems to be already handled in xen/x86, but we must be sure it
is also handled in xen/ia64.
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?
