# linsysfs.4

`linsysfs` — Linux 内核对象文件系统

## 名称

`linsysfs`

## 概要

```sh
linsysfs		/compat/linux/sys	linsysfs	rw 0 0
```

## 描述

Linux 系统文件系统，或 `linsysfs`，模拟 Linux sys 文件系统的一个子集，某些 Linux 二进制文件的完整运行需要它。

`linsysfs` 提供设备的二级视图。在最高级别，PCI 设备本身根据其在系统层次结构中的总线、插槽和功能命名。PCI 存储设备列在 `scsi_host` 类中，并带有指向设备 PCI 目录的设备符号链接。

每个设备节点是一个包含一些文件和目录的目录：

**`host`** 存储主机信息的占位符。

**`pci_id`** `pci_id` 的目录，包含设备信息或 PCI 桥的另一个目录结构。

scsi\_host 的每个 host 节点是一个包含一些文件和目录的目录：

**`proc_name`** 这些设备的 Linux 注册驱动名称。

**`device`** 指向 PCI 设备目录的符号链接。

## 文件

**`/compat/linux/sys`** `linsysfs` 的正常挂载点。

**`/compat/linux/sys/class/scsi_host`** 存储主机节点。

**`/compat/linux/sys/devices/pci0000:00`** PCI 设备层次结构节点。

## 实例

最常见的用法如下：

```sh
mount -t linsysfs linsysfs /compat/linux/sys
```

其中 **/compat/linux/sys** 是挂载点。

## 历史

`linsysfs` 驱动最早出现于 FreeBSD 6.2。

## 作者

`linsysfs` 驱动由 Doug Ambrisko 从 `linprocfs` 派生。本手册页由 Doug Ambrisko 编辑，基于 Garrett Wollman 的 [linprocfs(4)](/man/man4/linprocfs.4.md) 手册页。

# Agent Instructions
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/linsysfs.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.
