NAME

     bhnd — Broadcom Home Networking Division interconnect bus

SYNOPSIS

     To compile this driver into the kernel, place the following lines in your kernel
     configuration file:

           device bhnd

     Alternatively, to load the driver as a module at boot time, place the following line in
     loader.conf(5):

           bhnd_load="YES"

DESCRIPTION

     The bhnd driver provides a unified kernel bus interface to the on-chip interconnects used in
     Broadcom Home Networking Division (HND) devices.

     The Broadcom HND device family consists of SoCs (System On a Chip) and host-connected
     chipsets based on a common library of Broadcom IP cores connected via an internal hardware
     bus architecture.  Drivers for these cores are implemented against the unified bhnd
     interface.

     The Sonic Inc. Silicon Backplane used in earlier HND devices is supported by the siba(4)
     BHND driver.

     The ARM AMBA-based interconnect used in later HND devices is supported by the bcma(4) BHND
     driver.

HISTORY

     The bhnd device driver first appeared in FreeBSD 11.0.
