AMDTEMP(4)		 BSD Kernel Interfaces Manual		    AMDTEMP(4)

NAME
     amdtemp — AMD CPU on-die digital thermal sensor

SYNOPSIS
     amdtemp* at pchb?

DESCRIPTION
     The amdtemp driver provides support for the on-die digital thermal sensor
     present on AMD K8, AMD Barcelona, AMD Phenom, AMD Griffin, and AMD Fusion
     CPUs.

     These sensors were officially introduced in AMD K8 Revision F processors,
     and provide 0.5 degC accuracy.  Precision was improved in Revision G
     chips, which provide two more bits for 0.25 degC steppings.  Each core
     has two temperature sensors, and there are up to two cores per CPU
     socket.

     AMD Barcelona, AMD Phenom, AMD Griffin, and AMD Fusion provide 0.125 degC
     accuracy and provide one temperature sensor for each CPU socket.

     The amdtemp driver reports temperatures through the envsys(4) API.

HISTORY
     The amdtemp driver first appeared in OpenBSD 4.4 named “kate”.  It was
     then ported to NetBSD 5.0.	 The driver has been renamed with support for
     newer AMD CPUs.

AUTHORS
     The amdtemp driver was written by Constantine A. Murenin
     ⟨cnst@openbsd.org⟩ whilst at the University of Waterloo.  It was adapted
     to NetBSD by Christoph Egger.
