Hope someone > can clarify this for me. 1: and 4,0: are inputs to the CPUID instruction. The 1: means this line is activated when CPUID is executed with EAX=1. The 4,0: means that this line is used when CPUID is executed with EAX=4 and ECX=0 (some CPUID leaves use ECX as a secondary index). -- Keir _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel |
