- AMD Family 17h Northbridge and Data Fabric Driver
driver provides the system access to the Northbridge and
Data Fabric devices on AMD Family 17h (Zen) processors allowing the
operating system to communicate with the system management unit (SMU).
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
Temperature information is available to the system via the fault management
architecture (FMA). The file system location and programming interface to
driver are considered Volatile
, subject to change without
notice, and should not be used directly. Raw temperature information can
be dumped through the FMA developer utility fmtopo.
