20 This feature enables a procfs file -- /proc/pci -- that provides a
21 summary of PCI devices in the system.
22
23 This feature has been deprecated as of v2.5.53, in favor of using the
24 tool lspci(8). This feature may be removed at a future date.
25
26 lspci can provide the same data, as well as much more. lspci is a part of
27 the pci-utils package, which should be installed by your distribution.
28 See <file:Documentation/Changes> for information on where to get the latest
29 version.
