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 microarchitecure.

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.
