.SH NAME
/proc/pci \- PCI devices
.SH DESCRIPTION
.TP
.I /proc/pci
This is a listing of all PCI devices found during kernel initialization
and their configuration.
.IP
This file has been deprecated in favor of a new
.I /proc
interface for PCI
.RI ( /proc/bus/pci ).
It became optional in Linux 2.2 (available with
.B 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
.B CONFIG_PCI_LEGACY_PROC
set), and finally removed altogether since Linux 2.6.17.
