As that's defined to return all zero's, and not cause any traps whatever value you use (unless the CPU is so old that it doesn't support CPUID, of course).This sounds encouraging, but is CPUID always trapped by the HVM code? It can be, and in practise yes it is so this could work. -- Keir _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel |
