# proc\_pci(5)

PCI devices

## NAME

/proc/pci - PCI devices

## DESCRIPTION

- */proc/pci*

  This is a listing of all PCI devices found during kernel initialization and their configuration.

-

  This file has been deprecated in favor of a new */proc* interface for PCI (*/proc/bus/pci*). It became optional in Linux 2.2 (available with **CONFIG\_PCI\_OLD\_PROC** set at kernel compilation). It became once more nonoptionally enabled in Linux 2.4. Next, it was deprecated in Linux 2.6 (still available with **CONFIG\_PCI\_LEGACY\_PROC** set), and finally removed altogether since Linux 2.6.17.
