[lm-sensors] Intel DQ45CB motherboard and weird sensors output

[Gabriel C]

Hello all ,

I got for some days an new Intel mobo ( http://www.intel.com/products/desktop/motherboards/dq45cb/dq45CB-overview.htm ) all seems to work fine
on it but the senors ( probably something related to HECI / AMT and friends but I am not sure is why I've added Anas Nashif to CC ).

In BIOS the HW monitoring is working but this is the ATM thing which does not work in Linux AFAIK.

sensors-detect detects an LM96000 chip ( with lm85 driver ? ) on smbus but all temperatures are empty ?;/

Here the output :

sudo sensors-detect
# sensors-detect revision 5337 (2008-09-19 17:05:28 +0200)

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.

We can start with probing for (PCI) I2C or SMBus adapters.
Do you want to probe now? (YES/no):
Probing for PCI bus adapters...
Use driver `i2c-i801' for device 0000:00:1f.3: Intel ICH10

We will now try to load each adapter module in turn.
Load `i2c-i801' (say NO if built into your kernel)? (YES/no):
Module loaded successfully.
If you have undetectable or unsupported I2C/SMBus adapters, you can have
them scanned by manually loading the modules before running this script.

We are now going to do the I2C/SMBus adapter probings. Some chips may
be double detected; we choose the one with the highest confidence
value in that case.
If you found that the adapter hung after probing a certain address,
you can specify that address to remain unprobed.

Next adapter: SMBus I801 adapter at f000 (i2c-0)
Do you want to scan it? (YES/no/selectively):

Seems to be the same as:
http://www.lm-sensors.org/ticket/2182

Please try to find out what your Super-I/O chip is. My current theory
is that the above output is from a WPCD377I, which is compatible with
the PC8374L except that it doesn't include hardware monitoring
features. Why the designers would have made the chip still answer on
the SMBus is beyond me.

So, please try to figure out if your Intel DQ45CB board has a PC8374L
or WPCD377I or something else. If it is confirmed that the WPCD377I
present itself as a disabled LM96000 I'll fix sensors-detect to no
longer report it as an LM96000.

I've found the following Super-I/O chip on the mobo :

Winbond WPCD377IAUFG

So it seems you are right.

OK, thanks for reporting. I have just committed a fix to sensors-detect
so that it will differentiate between LM96000/PC8374L (have sensors)
and WPCD377I (no sensors) on the SMBus. Please give it a try:
http://www.lm-sensors.org/svn/lm-sensors/trunk/prog/detect/sensors-detect

The next step would be to differentiate between PC8374L and WPCD377I on
the LPC bus. I don't know how do to that though, as I don't have any
datasheet for the WPCD377I. I'll ask my contact at Nuvoton. In the
meantime, can you please provide the output of the following command:

isadump 0x2e 0x2f 8

Thanks,

Thanks , I will test when I'm home and report back.

Sure , here it is :

It does work for me , the new output is :

...

Probing for `National Semiconductor LM96000 or PC8374L'...  No
...

Probing for `Winbond WPCD377I'...                           Yes
    (confidence 7, not a hardware monitoring chip)

..

Jean it is possible these chips have something to do with Intel's QST ?

As expected. Thanks for reporting.

No, they do not. The idea (as far as I understand it) is that these
boards have Super-I/O chips with reduced features (no hardware
monitoring) because the south bridge (ICH8+) has QST support. So you
need AMT/QST support for hardware monitoring features.

Ah ok. I do have AMT ( heci linux driver ) but open source QST SDK is not yet released :/

However according to http://software.intel.com/en-us/forums/manageability-software-development/topic/54851/reply/74068/
with an NDA one could get a copy of the SDK even yet.
