linux查看硬件信息及驅動設備相關整理【轉】

藍貓 發布于：2014-5-30 17:48　分類：技術文章 　有 0 人瀏覽，獲得評論 0 條　標簽:linux硬件信息

在LINUX環境開發驅動程序，首先要探測到新硬件，接下來就是開發驅動程序。

常用命令整理如下：

用硬件檢測程序kuduz探測新硬件：service kudzu start ( or restart)

查看CPU信息：cat /proc/cpuinfo

查看板卡信息：cat /proc/pci

查看PCI信息：lspci (相比cat /proc/pci更直觀)

查看內存信息：cat /proc/meminfo

查看USB設備：cat /proc/bus/usb/devices

查看鍵盤和鼠標:cat /proc/bus/input/devices

查看系統硬盤信息和使用情況：fdisk & disk - l & df

查看各設備的中斷請求(IRQ):cat /proc/interrupts

查看系統體系結構：uname -a

dmidecode查看硬件信息，包括bios、cpu、內存等信息

dmesg | more 查看硬件信息

我的FC5顯示結果如下：
