What hardware devices are available in the system? Method 1: Use the lsdev command to display the devices in the system and their features. For example: lsdev-C, but this command may not be available on the general system. For example, the ora command I installed does not exist. Method 2: display the/proc/dev file, which records some hardware information of the system, for example: cat/proc/dev method 3: to find a specific usb device, you can use the lsusb command to list all usb devices. If you want to find a specific pcmcia device, you can use the lspcmcia command to list all pcmcia devices. If you want to find a specific pci device, you can use the lspci command to list all pcm devices. In Linux, view hardware information and driver devices. In Linux, view hardware information and use the hardware detection program kudzu to test new hardware: service kudzu start (or restart). View CPU information: cat/proc/cpuinfo view Board information: cat/proc/pci view PCI information: lspci (more intuitive than cat/proc/pci) view memory information: cat/proc/meminfo view USB device: cat/proc/bus/usb/devices view keyboard and mouse: cat/proc/bus/input/devices view system hard disk information and usage: fdisk & disk-l & df view interrupt requests of each device (IRQ): cat/proc/interrupts view system architecture: uname-a development of drivers in LINUX environment, first, we need to detect new hardware, and then develop the driver. Common commands are as follows: Use the hardware detection program kudzu to detect new hardware: service kudzu start (or restart) to view CPU information: cat/proc/cpuinfo to view Board information: cat/proc/pci view PCI information: lspci (more intuitive than cat/proc/pci) view memory information: cat/proc/meminfo view USB device: cat/proc/bus/usb/devices view keyboard and mouse: cat/proc/bus/input/devices view system hard disk information and usage: fdisk & disk-l & df view interrupt requests of each device (IRQ): cat/proc/interrupts view system architecture: uname-a dmidecode view hardware information, including bios, cpu, memory and other information dmesg | more view hardware information for "/proc" files can be viewed using the file view command to view its content, the file contains system-specific information: cpuinfo host CPU information Dma host DMA channel information Filesystems File System Information Interrupts host interrupt information Ioprots host I/O port number information Meninfo host memory information Version Linux memory Version information
