AMDTEMP(4)	       FreeBSD Kernel Interfaces Manual		    AMDTEMP(4)

NAME
     amdtemp --	device driver for AMD K8, K10 and K11 on-die digital thermal
     sensor

SYNOPSIS
     To	compile	this driver into the kernel, place the following line in your
     kernel configuration file:

	   device amdtemp

     Alternatively, to load the	driver as a module at boot time, place the
     following line in loader.conf(5):

	   amdtemp_load="YES"

DESCRIPTION
     The amdtemp driver	provides support for the on-die	digital	thermal	sensor
     present in	AMD K8,	K10 and	K11 processors.

     For the K8	family,	the amdtemp driver reports each	core's temperature
     through a sysctl node in the corresponding	CPU devices's sysctl tree,
     named dev.amdtemp.%d.sensor{0,1}.core{0,1}.  The driver also creates
     dev.cpu.%d.temperature displaying the maximum temperature of the two sen-
     sors located in each CPU core.

     For the K10 and K11 families, the driver creates dev.cpu.%d.temperature
     with the temperature of each core.

SEE ALSO
     sysctl(8)

HISTORY
     The amdtemp driver	first appeared in FreeBSD 7.1.

BUGS
     AMD K9 is not supported because temperature reporting has been replaced
     by	Maltese.
