Modes of Operation - 006 - ID:631119 | Intel® 500 Series Chipset Family On-Package PCH Datasheet Volume 1
On some Intel client platforms like SKL/KBL/CNL/CML, there is a
PCH thermal sensor that monitors the PCH temperature and blocks the system
from entering S0ix in case it overheats.
Wondering why they specify these platforms omitting 12th 11th or 8th intel platforms gen.
