This is the Linux CPU number. ie the namespace where 0 is the boot processor and the others are numbered in the order that they were started. > and then call them CPU1 and CPU2 in >/proc/acpi/processor? These are arbitrary device identifiers written by the BIOS developer and foolishly advertised to the user by Linux. The BIOS writer could have also called them ABC9 and XYZ4 and it would be equally valid. We're planning to get rid of all the ACPI stuff in /proc and move to sysfs. At that time we'll use device identifies that are deterministic, like cpu%d that /sys/devices/system uses today. cheers, -Len - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
