Subject: CPU Model IDs(string) inconsistant on SMP AMD System (2.4.18-rc4)
Date: Thu, 28 Mar 2002 12:05:12 -0800 [thread overview]
Message-ID: <3CA37778.9090009@fourelle.com> (raw)
I am working with several SMP Athlon machines, and they are all
reporting the first CPUs
model ID(*** called 'model name' in /proc/cpuinfo) as 'AMD Athlon(tm) MP
1800+' and the
second CPUs model ID as 'AMD Athlon(tm) Processor'.
From looking at the code it seems that the model IDs are obtained using
cpuid calls. Does
anyone have insight into this?
Some Info:
Motherboard: Tyan S2462NG
CPUs: 2 Athlon MP 1800+
Kernel Version: 2.4.18-rc4
