Incorrect SMP topology reported on AMD K7 MP system
From: Bill Johnstone
Date: Tue May 13 2008 - 17:00:42 EST
Hello.
I have some older cluster nodes running dual AMD Athlon MP 2600+ processors on Tyan S2469 motherboards, running the latest BIOS that Tyan released, version 1.08 .
Issue: the number of processors and sockets on this system is 2. The second processor has a /sys/devices/system/cpu/cpu1/topology/physical_package_id value of 0, whereas it should be 1. /proc/cpuinfo looks OK and the kernel seems to recognize and otherwise deal with both processors correctly.
The kernel is a Gentoo version of 2.6.22 . The dmesg is below.
Is this an issue with the kernel or the motherboard BIOS / ACPI? If the latter, can it be worked around somehow?
