Hi, I am trying to use the grant tables mechanism to do allocate memory in domU and obtain a struct page * for that memory in dom0. I do the following in domU: 1. __get_free_pages 2. virt_to_mfn 3. gnttab_grant_foreign_access Now I have a reference which I pass to dom0. In dom0 I would like but don''t know how to do: 1. Get the refrence to the page without mapping it to dom0 address space (all I want is make sure the page is still owned by domU so I want to use the passed reference). 2. Use a "mfn to struct page *" call. Is that possible? Thanks. _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel
