NAME

coretemp - Intel core-family temperature sensor driver

SYNOPSIS

/dev/sensors/temperature/cpu/*

DESCRIPTION

The coretemp driver provides the system with a means of reading the
per-core and, when available, per-package digital temperature sensors
on Intel CPUs. Currently, the coretemp driver supports Intel Core
family processors after Penryn microarchitecture and Intel Atom
processors starting with the Silvermont microarchitecture.

Temperature information is available to the system via the fault
management architecture (FMA). The file system location and
programming interface to the coretemp 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.
