lspci没有打印出任何东西

[chengshuyi]

因为想要查看自己的网卡型号，所以运行了下面的命令

代码： 全选

lspci | grep -i net

但是没有任何输出，运行lspci也是没有任何输出。


我个人感觉是不是PCI模块没有加载进来，但是又不太清楚。下面是我的当前配置和PCI有关的输出：

命令：

代码： 全选

zgrep -i pci /proc/config.gz

输出：

你的系统环境是什么？有些嵌入式环境就是没有pci总线，用了openvz虚拟技术的主机也不给你访问pci总线的机会。这些情况下都不会有输出。看看/proc/bus/pci存在不

你好，我的系统环境是:

代码： 全选

Linux tegra-ubuntu 4.4.38 #3 SMP PREEMPT Wed Oct 17 10:21:25 UTC 2018 aarch64 aarch64 aarch64 GNU/Linux

板子是Jetson TX2

/proc/bus/pci存在，下面有个devices文件，但是里面是空的。

[poloshiao]

lspci | grep -i net

先試試
lspci
或
sudo lspci
看看 有沒有任何回應

[astolia]

说明你的板子有pci总线，但网卡不是走的pci接口。先lsusb看看是不是走的usb，还没有的话lshw看，再不行就去找nvidia官方文档
