NAME
       /proc/pci - PCI devices

DESCRIPTION
       /proc/pci
              This is a listing of all PCI devices found during kernel initialization and their con‐
              figuration.

              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.
