CPU Monitoring: Where is the PECI datasheet ?

Hello,

I'm trying to get the CPU T°C through the PECI register like it is introduced in many Intel processors datasheet.

Unfortunately I can't find any technical information about the PECI commands. However this is written in many datasheets:

PECI command support is covered in detail in Platform Environment Control Interface

 

Specification. Please refer to this document for details on supported PECI command function and codes. 

I searched a lot but I can't find this document nowhere. Should I send an e-mail to intel support to get it ?

Thanks !

PECI itself is not very feature rich. there are two commands.

Yep, it's OK I wasn't searching at the good place.

I just have to read the IA32_THERM_STATUS(019Ch) Register (MSR) to get Digital Sensor data. I've found that in the "Intel® 64 and IA-32 Architectures Software Developer's Manual -- Volume 3A: System Programming Guide".

Thank's !
