🦋 BHND(4) — Broadcom Home Networking Division interconnect bus

okay so this page is from the Kernel Interfaces Manual, and it's giving very specific kernel-bus energy. bestie, meet bhnd: the Broadcom Home Networking Division interconnect bus. 💅

✨ NAME ✨

bhnd — Broadcom Home Networking Division interconnect bus. that's the whole name section, and yes, it ate.

🎀 SYNOPSIS 🎀

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

device bhnd

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. like, one interface to rule them all, no cap.

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 way that architecture is all “common library of IP cores” and the drivers all line up behind one interface? iconic.

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

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