Lspci
Encyclopedia
lspci is a command on Unix-like
operating systems that prints detailed information about all PCI buses and device
s in the system. It is based on a common portable library libpci which offers access to the PCI configuration space on a variety of operating systems.
Example output on a Linux
system:
If many devices are shown as unknown (e.g. "Unknown device 2830 (rev 02)), issuing the command 'update-pciids' will usually
do the trick.
