---help---
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.
When in doubt, say N.
