+.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 .
