AMDTEMP(4) BSD 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 cores' 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.
BUGS
AMD K9 is not supported because temperature reporting has been replaced by Maltese.

HISTORY
