It's pretty obviously not the correct thing to do since it is not generally the case that apicid == cpuid+4. The latter id space does not even have a guaranteed ordering across physical cores and sockets! This is why you were discussing reviving code in mpparse.c, because this relationship must be established dynamically, right? -- Keir _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel |
