1、linux 查看硬件信息及驱动设备相关整理在 LINUX 环境开发驱动程序，首先要探测到新硬件，接下来就是开发驱动程序。 常用命令整理如下：用硬件检测程序 kuduz 探测新硬件： 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 更直观) 查看内存信息： cat /proc/meminfo 查看 USB 设备： cat /proc/bus/usb/devices 查看键盘和鼠标 :cat /proc/bus
2、/input/devices 查看系统硬盘信息和使用情况： fdisk & disk - l & df 查看各设备的中断请求 (IRQ):cat /proc/interrupts 查看系统体系结构：un ame -a查看主机序列号： dmidecode -t 1 查看主机 HBA 卡 WWN 号： systool -c fc_host -v dmidecode 查看硬件信息，包括 bios 、 cpu 、内存等信息 dmesg | more 查看硬件信息 我的 FC5 显示结果如下：查看键盘和鼠标rootlocalhost input# cat /proc/bus/input/devicesI
