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.
