+.Sh SYNOPSIS
+.Pa /dev/sensors/temperature/cpu/*
+.Sh DESCRIPTION
+The
+.Nm
+driver provides the system access to the Northbridge and Data Fabric
+devices on AMD Family 17h
+.Pq Zen
+processors allowing the operating system to communicate with the system
+management unit
+.Pq SMU .
+.Pp
+From this, the driver exposes temperature sensors.
+On Family 17h systems, temperature sensors exist for each Zeppelin die,
+of which there may be multiple in a single package.
+This means that each sensor covers more than one core.
+.Pp
+Temperature information is available to the system via the fault
+management architecture
+.Pq FMA .
+The file system location and programming interface to the
+.Nm
+driver are considered
+.Sy Volatile ,
+subject to change without notice, and should not be used directly.
+Raw temperature information can be dumped through the FMA developer
+utility fmtopo.
