# bhnd.4

`bhnd` — Broadcom 家庭网络部门互连总线

## 名称

`bhnd`

## 概要

要将此驱动编译进内核，请在内核配置文件中加入以下行：

> device bhnd

要在引导时以模块形式加载该驱动，请在 loader.conf(5) 中加入以下行：

```sh
bhnd_load="YES"
```

## 描述

`bhnd` 驱动为 Broadcom 家庭网络部门（HND）设备中使用的片上互连提供统一的内核总线接口。

Broadcom HND 设备家族由 SoC（System On a Chip，片上系统）和主机连接的芯片组组成，基于通过内部硬件总线架构连接的通用 Broadcom IP 核库。这些核心的驱动针对统一的 `bhnd` 接口实现。

早期 HND 设备中使用的 Sonic Inc. Silicon Backplane 由 [siba(4)](/man/man4/siba.4.md) BHND 驱动支持。

后续 HND 设备中使用的基于 ARM AMBA 的互连由 [bcma(4)](/man/man4/bcma.4.md) BHND 驱动支持。

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://book.bsdcn.org/man/man4/bhnd.4.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
