Even better would be to accept cr3, cr4 and efer msr. That's sufficient to work out the execution mode (non-pae, pae, 64-bit). Or the caller could work out the mode and pass it in as an enumeration value (perhaps with a fallback default of 'whatever is most likely'). -- Keir _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel |
