大家好，又见面了，我是你们的朋友全栈君。

1. 指令名称

代码语言：javascript

lspci

2. 指令简介

lspci 是一个用于显示系统中所有 PCI/PCIe 总线及设备信息的工具。

默认情况下，它只显示设备的最简要信息。通过传入指定参数，可以输出更详细的信息，或者可以按照特定格式输出，以便于用其他程序进行解析。

有些 PCI/PCIe 的设备信息需要在 root 权限下才能获取到。

3. 参数

先来看看不加任何参数时输出的结果。

3.4 指定设备

通过下面的两种方法指定某一个设备，结合上面介绍的参数，即可完成对特定设备的操作。

-s [[[[<domain>]:]<bus>]:][<device>][.[<func>]] : 通过 domain、bus、device、function 指定某一个设备进行操作。所有的值都是 16 进制，domain 的取值范围是 0~ffff，bus 的取值范围是 0~ff，device 的取值范围是 0~1f，function 的取值范围是 0~7。如果不指定值或者设置为 * 号，则代表“任何值”。例如，“0:”代表 bus 0 上的所有 device；“0”代表 deivice 0 上的所有 functions；“0.3”代表选择所有 bus 上的 device 0 的第 3 个 function；“.4”代表所有 device 的第 4 个 function。
