When in real mode to protected mode transition, only the IP address calculation should use real mode addressing. Yes, I'll push this one: I like the extra sanity checking. Why are the checks for zero and greater-than-gdt-limit required (why is it insufficient to merely check the current mode)? -- Keir _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel |
