Hi,
I have a machine running Motherboard: Supermicro H8DGU with AMD Opteron 6380 (16-core) x2 CPUs. Its running Ubuntu Server 12.04.3 LTS, uname -a: Linux sysname 3.5.0-23-generic #35~precise1-Ubuntu SMP Fri Jan 25 17:13:26 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux
I have installed sensors version 3.3.2 with libsensors version 3.3.1. The output of sensors-detect is as follows:

This program will help you determine which kernel modules you need
to load to use lm_sensors most effectively. It is generally safe
and recommended to accept the default answers to all questions,
unless you know what you're doing.
Some south bridges, CPUs or memory controllers contain embedded sensors.
Do you want to scan for them? This is totally safe. (YES/no):
Silicon Integrated Systems SIS5595... No
VIA VT82C686 Integrated Sensors... No
VIA VT8231 Integrated Sensors... No
AMD K8 thermal sensors... No
AMD Family 10h thermal sensors... No
AMD Family 11h thermal sensors... No
AMD Family 12h and 14h thermal sensors... No
AMD Family 15h thermal sensors... Success!
(driver `k10temp')
AMD Family 15h power sensors... Success!
(driver `fam15h_power')
Intel digital thermal sensor... No
Intel AMB FB-DIMM thermal sensor... No
VIA C7 thermal sensor... No
VIA Nano thermal sensor... No
Some Super I/O chips contain embedded sensors. We have to write to
standard I/O ports to probe them. This is usually safe.
Do you want to scan for Super I/O sensors? (YES/no):
Probing for Super-I/O at 0x2e/0x2f
Trying family `National Semiconductor/ITE'... No
Trying family `SMSC'... No
Trying family `VIA/Winbond/Nuvoton/Fintek'... Yes
Found `Winbond W83627DHG-P/W83527HG Super IO Sensors'
(address 0xa10, but not activated)
Probing for Super-I/O at 0x4e/0x4f
Trying family `National Semiconductor/ITE'... No
Trying family `SMSC'... No
Trying family `VIA/Winbond/Nuvoton/Fintek'... No
Trying family `ITE'... No
Some systems (mainly servers) implement IPMI, a set of common interfaces
through which system health data may be retrieved, amongst other things.
We first try to get the information from SMBIOS. If we don't find it
there, we have to read from arbitrary I/O ports to probe for such
interfaces. This is normally safe. Do you want to scan for IPMI
interfaces? (YES/no):
Found `IPMI BMC KCS' at 0xca2... Success!
(confidence 8, driver `to-be-written')
Some hardware monitoring chips are accessible through the ISA I/O ports.
We have to write to arbitrary I/O ports to probe them. This is usually
safe though. Yes, you do have ISA I/O ports even if you do not have any
ISA slots! Do you want to scan the ISA I/O ports? (YES/no):
Probing for `National Semiconductor LM78' at 0x290... No
Probing for `National Semiconductor LM79' at 0x290... No
Probing for `Winbond W83781D' at 0x290... No
Probing for `Winbond W83782D' at 0x290... No
Lastly, we can probe the I2C/SMBus adapters for connected hardware
monitoring devices. This is the most risky part, and while it works
reasonably well on most systems, it has been reported to cause trouble
on some systems.
Do you want to probe the I2C/SMBus adapters now? (YES/no):
Using driver `i2c-piix4' for device 0000:00:14.0: ATI Technologies Inc SB600/SB700/SB800 SMBus
Next adapter: SMBus PIIX4 adapter at 0b00 (i2c-0)
Do you want to scan it? (YES/no/selectively):
Now follows a summary of the probes I have just done.
Just press ENTER to continue:
Driver `to-be-written':
* ISA bus, address 0xca2
Chip `IPMI BMC KCS' (confidence: 8)
Driver `fam15h_power' (autoloaded):
* Chip `AMD Family 15h power sensors' (confidence: 9)
Driver `k10temp' (autoloaded):
* Chip `AMD Family 15h thermal sensors' (confidence: 9)
Note: there is no driver for IPMI BMC KCS yet.
Check http://www.lm-sensors.org/wiki/Devices for updates.
No modules to load, skipping modules configuration.
And this is the is the output of sensors:
fam15h_power-pci-00c4
Adapter: PCI adapter
power1: 41.15 W (crit = 114.49 W)
fam15h_power-pci-00d4
Adapter: PCI adapter
power1: 40.99 W (crit = 114.49 W)
k10temp-pci-00c3
Adapter: PCI adapter
temp1: +15.0°C (high = +70.0°C)
(crit = +70.0°C, hyst = +67.0°C)
k10temp-pci-00cb
Adapter: PCI adapter
temp1: +15.4°C (high = +70.0°C)
k10temp-pci-00d3
Adapter: PCI adapter
temp1: +15.0°C (high = +70.0°C)
(crit = +70.0°C, hyst = +67.0°C)
k10temp-pci-00db
Adapter: PCI adapter
temp1: +15.1°C (high = +70.0°C)
I am getting no CPU/CPU core temperature readings at all. And I don't know these PCI Adapter temperature readings exactly represent. Is my motherboard and CPU supported? If so what am I doing wrong or not doing? Kindly help me out here!
k10temp _is_ the CPU temperature. The readings are notoriously
unreliable, especially at low temperatures. You should see
the readings go up with higher load.
Guenter
Thanks for the info! but isn't it also supposed to show core temperatures? And regardless of that, The machine has 2 AMD Opteron 6380 CPUs, so why exactly is it showing 4 temperature readings? Shouldn't they just be 2?
I don't know exactly what readings those CPUs provide. The datasheet should tell.
The output itself suggests that it is for two different CPUs; you can see that there
are four sensors, two of which support critical temperature readings and two don't.
So it looks like you get two readings per CPU. Possibly one is the package temperature
and one is the CPU temperature. Again, the datasheet should tell you what exactly
it is (or maybe someone on the list knows better than me).
