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