# acpi\_asus\_wmi.4

`acpi_asus_wmi` — Asus 笔记本 WMI 附加功能

## 名称

`acpi_asus_wmi`

## 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 acpi\_asus\_wmi

`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
acpi_asus_wmi_load="YES"
```

## 描述

`acpi_asus_wmi` 驱动为 Asus 笔记本上由 WMI 控制的附加设备（如热键和 LED）提供支持。它允许使用 [sysctl(8)](/man/man8/sysctl.8.md) 接口调节 LCD 面板和键盘背光的亮度、开启或关闭 WiFi、蓝牙、摄像头、读卡器等内部组件，以及读取某些传感器。热键事件会传递给 devd(8)，以便在用户空间中借助 **`/etc/devd/asus.conf`** 中的默认配置轻松处理。一些热键事件，例如键盘背光和触摸板控制，由驱动内部处理。

## SYSCTL 变量

当前实现了以下 sysctl：

**`dev.acpi_asus_wmi.0.handle_keys`** 指定驱动是否应在内部处理某些硬件按键，例如键盘背光。

同一 sysctl 分支下的其他许多变量与具体型号相关。

这些变量的默认值可在 [sysctl.conf(5)](/man/man5/sysctl.conf.5.md) 中设置，该文件在引导时解析。

## 文件

**`/dev/backlight/acpi_asus_wmi0`** 键盘 backlight(8) 设备节点。

## 历史

`acpi_asus_wmi` 驱动最早出现在 FreeBSD 10.0 中。

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/acpi_asus_wmi.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.
