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.conf5:

 amdtemp_load="YES"
 

DESCRIPTION

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

For the K8 family, the 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AMD K9 is not supported because temperature reporting has been replaced by Maltese.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

The driver first appeared in Fx 7.1 .
