Slight aside: If/when we ever manage to find a system which doesn't need 1:1 for dom0 RAM and therefore can support this latter case we will probably need to revisit the selection of the memory region for both the gnttab and these tables rather than hope it is unlikely they will clash. But for now using the same mechanism for these tables as we do for the gnttab region makes sense, and if/when things change the answer will likely be the same. _______________________________________________ Xen-devel mailing list Xen-devel@lists.xen.org http://lists.xen.org/xen-devel
