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AMD K9 is not supported because temperature reporting has been replaced
by Maltese.

The amdtemp driver first appeared in FreeBSD 7.1.
