Hi Keir, Do you mean that we should leave 80000008:ECX[15:12] as zero or in old way (i.e. (regs[2] & 0xf000u) + 1))? These bits can't be zero, unless we want to use legacy method in multi-core calculation. -Wei ======== I think you shouldn't change handling of 80000008:ECX[15:12] since that does explicitly refer to APIC ID arrangement. The rest of your changes could be correct as far as I can tell from the reference manuals. _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel |
