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 sensors located in each CPU
     core.

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

HISTORY
     The amdtemp driver first appeared in FreeBSD 7.1.

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     AMD K9 is not supported because temperature reporting has been replaced by Maltese.
