  19 .Nd Intel platform controller hub temperature sensor driver
  20 .Sh SYNOPSIS
  21 .Pa /dev/sensors/temperature/pch/*
  22 .Sh DESCRIPTION
  23 The
  24 .Nm
  25 driver provides the system the ability to read the digital temperature
  26 sensor found on several Intel platform controller hub (PCH) chipsets.
  27 The following chipsets are supported which cover most Intel Core familiy
  28 (non-Atom) CPUs starting with the Haswell generation:
  29 .Bl -dash

  49 Temperature information is available to the system via the fault
  50 management architecture
  51 .Pq FMA .
  52 The file system location and programming interface to the
  53 .Nm
  54 driver are considered
  55 .Sy Volatile ,
  56 subject to change without notice, and should not be used directly.
  57 Raw temperature information can be dumped through the FMA developer
  58 utility
  59 .Sy fmtopo .
