|
|
.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
|
