NAME

pchtemp - Intel platform controller hub temperature sensor driver

SYNOPSIS

/dev/sensors/temperature/pch/*

DESCRIPTION

The pchtemp driver provides the system the ability to read the digital
temperature sensor found on several Intel platform controller hub (PCH)
chipsets. The following chipsets are supported which cover most Intel
Core family (non-Atom) CPUs starting with the Haswell generation:

- Intel 8 Series / C220 Series Chipset Platform Controller Hub

- Intel 9 Series Chipset Family Platform Controller Hub

- Intel Mobile 5th Generation Processor Family (Broadwell-U)

- Intel C610 Series Chipset and X99 Chipset Platform Controller Hub

- Intel 100 Series Chipset Family Platform Controller Hub

- Intel C620 Series Chipset Platform Controller Hub

- Intel 200 and Z370 Series Chipset Families Platform Controller Hub

- Intel 7th/8th Generation Processor Family U/Y Platforms

- Intel 300 Series and Intel C240 Series Chipset Family Platform
Controller Hub

- Intel 400 Series Chipset Family On-Package Platform Controller Hub

- Intel 400 Series Chipset Family Platform Controller Hub

Temperature information is available to the system via the fault
management architecture (FMA). The file system location and
programming interface to the pchtemp driver are considered Volatile,
subject to change without notice, and should not be used directly. Raw
temperature information can be dumped through the FMA developer utility
fmtopo.
