.Sh NAME
.Nm k8temp
.Nd device driver for AMD K8 on-die digital thermal sensor
.Sh SYNOPSIS
To compile this driver into the kernel,
place the following line in your
kernel configuration file:
.Bd -ragged -offset indent
.Cd "device k8temp"
.Ed
.Pp
Alternatively, to load the driver as a
module at boot time, place the following line in
.Xr loader.conf 5 :
.Bd -literal -offset indent
k8temp_load="YES"
.Ed
.Sh DESCRIPTION
The
.Nm
driver provides support for the on-die digital thermal sensor present
in AMD K8 processors.
.Pp
The
.Nm
driver reports each cores' temperature through a sysctl node in the
corresponding CPU devices's sysctl tree, named
.Va dev.k8temp.%d.sensor{0,1}.core{0,1} .
.Va dev.cpu.%d.temperature
is also created and it displays the maximum temperature of the two sensors
located in each CPU core.
.Sh SEE ALSO
.Xr sysctl 8
.Sh HISTORY
The
.Nm
driver first appeared in
.Fx 7.1 .
