Intel Mainboards #191

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
Hey there,

it is not that important, but on my Intel Mainboard i get CPU Temperature, but 
the mainboard itself is not recognized.

As this mainboards are used often on servers, i thought it would be nice for 
you to get it supported.

This time i attached the Report.

The Intel S3210SH mainboard seems to use a PC8374L SensorPath Super I/O. This 
is documented in the spec 
http://download.intel.com/support/motherboards/server/s3200sh/sb/e14960_002_s320
0sh_s3210sh_tps_11.pdf

This agrees also with the chip ID 0xF111 detected by the Open Hardware Monitor. 
But the PC8374L is used only for floppy, keyboard and mouse support (that's at 
least what the Intel doc says).

From the above document, the fan control and temperature / voltage sensors are 
attached to a "iBMC" chip (Integrated Baseboard Management Controller). So far 
I do not if and how this iBMC can be accessed. For adding support some kind of 
documentation / interface is required.

i have request on this page for documents, perhaps its not the 100% right 
direction, but hopefully we get some clues on this,

thank you for sharing your time with this issue.

The BMC is just a controller, and I guess one would need to know details of the 
firmware running on it as well. I am not sure, but perhaps this is connected to 
the IPMI from Intel 
http://en.wikipedia.org/wiki/Intelligent_Platform_Management_Interface

Could you test if you can access the sensors with 
http://ipmiutil.sourceforge.net/
I guess you would need the "isensor" command. If this does not work, you could 
also check if there are any other official tools / interfaces that Intel 
documents for your system.

i wrote an email to nuvoton who produces the "Winbond PC8374L super I/O chip" 

They emailed me this:

/////
As far as I know we do not have a BMC on Intel server platforms. From the 
attached specification (I found on the web) the on-board BMC in a ServerEngines 
LLC Pilot II controller.

Our product is the “Winbond PC8374L super I/O chip” which can communicate 
with thermal sensors on board via either SMBus or SensorPath, which I’m not 
sure is used in this platform.

The PECI interface to the CPU is controlled by the ICH9 (chipset).
