How to Use lspci to View Linux Hardware

Meet the lspci command to view the hardware that Linux was able to recognize.

lspci is useful for displaying all the information about the system's PCI buses and the devices connected to them.

Its most common options are:

• -v  Shows detailed information about all devices.
• -vv           Shows even more information about the devices.
• -n Shows the vendor and device codes.
• -x  Shows the first 64 bytes of the PCI configuration in hexadecimal.
• -xxx         Shows the entire PCI configuration in hexadecimal.
