17.Sh NAME
18.Nm coretemp
19.Nd Intel core-family temperature sensor driver
20.Sh SYNOPSIS
21.Pa /dev/sensors/temperature/cpu/*
22.Sh DESCRIPTION
23The
24.Nm
25driver provides the system with a means of reading the per-core and,
26when available, per-package digital temperature sensors on Intel CPUs.
27Currently, the
28.Nm
29driver supports Intel Core family processors after Penryn
30microarchitecture and Intel Atom processors starting with the Silvermont
31microarchitecture.
32.Pp
33Temperature information is available to the system via the fault
34management architecture
35.Pq FMA .
36The file system location and programming interface to the
37.Nm
38driver are considered
39.Sy Volatile ,
40subject to change without notice, and should not be used directly.
41Raw temperature information can be dumped through the FMA developer
42utility fmtopo.
