NAME
k8temp - device driver for AMD K8 on-die digital thermal sensor
SYNOPSIS
To compile this driver into the kernel, place the following line in your
kernel configuration file:

DESCRIPTION
The k8temp driver provides support for the on-die digital thermal sensor
present in AMD K8 processors.
The k8temp driver reports each cores’ temperature through a sysctl node
in the corresponding CPU devices’s sysctl tree, named
dev.k8temp.%d.sensor{0,1}.core{0,1}. dev.cpu.%d.temperature is also
created and it displays the maximum temperature of the two sensors
located in each CPU core.
SEE ALSO
sysctl(8)
HISTORY
The k8temp driver first appeared in FreeBSD 7.1.
