This was not the case historically. AP on 6 was the standard for the boards PHK and Jack Vogel had. I know that there was code to rewrite the APIC ID to linearize them, at one time. Is it now being assumed that it's linear? The ID is basically assigned by the BIOS, and is supposed to be a number between 0 and 31, with no guarantee of adjacency or anything... -- Terry To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-smp" in the body of the message
