(3) pass two values: 32bit page frame number & flags. (4) others? I'd prefeare option (1), option (3) is reasonable as well I think. I don't think (2) is a good idea, that will cause some very nasty problems in case we'll try to allow non-PAE guests in PAE mode. Comments? I like option 3. -- Keir _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel |
