/proc/pci - PCI devices
/proc/pciThis 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.
