# superio.4

`superio` — Super I/O 控制器和总线驱动

## 名称

`superio`

## 概要

`要将此驱动编译进内核，请在你的内核配置文件中加入以下行：`

> device superio

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

```sh
superio_load="YES"
```

## 描述

Super I/O 是一种 I/O 控制器，组合了多种功能上彼此可能不相关的低带宽设备。典型的 Super I/O 可包含如下设备

* 软盘控制器
* 并口
* 串口
* PS/2 鼠标和键盘控制器
* 硬件监控控制器
* 看门狗定时器
* 通用输入输出控制器

`superio` 驱动为位于 Super I/O 控制器中、只能使用控制器接口访问或发现的设备提供支持。某些 Super I/O 设备具有标准化接口。此类设备要么使用众所周知的遗留资源，要么通过 ACPI 通告，或两者兼有。它们可使用 ISA 总线 hints 配置，或由 [acpi(4)](/man/man4/acpi.4.md) 自动配置。`superio` 驱动并非为与此类设备交互而设计。它们可由各自的驱动处理，无需了解 Super I/O 的具体细节。例如，[fdc(4)](/man/man4/fdc.4.md) 提供对软盘控制器的访问。

其他 Super I/O 设备没有任何标准化接口。可使用 `superio` 驱动的功能为这些设备编写驱动。

驱动本身附加到 ISA 总线，因为所有受支持的控制器都通过 LPC I/O 端口访问。

`superio` 驱动不同寻常，因为它既是各种 Super I/O 控制器的控制器驱动，也是这些控制器中受支持设备的总线驱动。

## 硬件

This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## 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/superio.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.
