Subject: [lm-sensors] How to distinguish sensors on Xeon multi-socket system
Date: Tue, 01 Feb 2011 20:23:13 +0000	[thread overview]
Message-ID: <201102012323.13215.4ernov@gmail.com> (raw)

Hello,

I have two socket motherboard with two Xeon's 5345 installed on them, so 
overall it's 8 cores. Using lm_sensors all of them are detected correctly out 
of the box, but the problem is that after certain Linux kernel upgrade (I 
believe it's somewhere around 2.6.32) matching kernel on both processors 
started to be called identically. I have two 'Core 0', two 'Core 1' etc. and 
it drives mad many applications which use lm_sensors. Here's the output of 
'sensors' command:
sensors
radeon-pci-0700
Adapter: PCI adapter
temp1:       +77.0°C                              

coretemp-isa-0000
Adapter: ISA adapter
Core 0:      +70.0°C  (high = +86.0°C, crit = +100.0°C)  

coretemp-isa-0001
Adapter: ISA adapter
Core 2:      +63.0°C  (high = +86.0°C, crit = +100.0°C)  

coretemp-isa-0002
Adapter: ISA adapter
Core 0:      +69.0°C  (high = +86.0°C, crit = +100.0°C)  

coretemp-isa-0003
Adapter: ISA adapter
Core 2:      +69.0°C  (high = +86.0°C, crit = +100.0°C)  

coretemp-isa-0004
Adapter: ISA adapter
Core 1:      +68.0°C  (high = +86.0°C, crit = +100.0°C)  

coretemp-isa-0005
Adapter: ISA adapter
Core 3:      +65.0°C  (high = +86.0°C, crit = +100.0°C)  

coretemp-isa-0006
Adapter: ISA adapter
Core 1:      +68.0°C  (high = +86.0°C, crit = +100.0°C)  

coretemp-isa-0007
Adapter: ISA adapter
Core 3:      +67.0°C  (high = +86.0°C, crit = +100.0°C)

I try to fix the KDE sensors applet as it shows only 4 cores and ignores 
remaining ones due to name collision. But I really don't know how to 
distinguish the certain cores of the processors. Could you please give me a 
reference how can I tell, for instance one 'Core 0' from another? The ideal 
case is if they can be addressed as 'Processor 1/Core 0' but I can't find the 
right way.

Thanks in advance!
