NAME¶

bhnd — Broadcom Home Networking Division interconnect bus

SYNOPSIS¶

To compile this driver into the kernel, add the following lines to the kernel configuration file:

To load the driver as a module at boot, add this line to 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.

SEE ALSO¶

HISTORY¶

The bhnd device driver first appeared in FreeBSD 11.0.
