9 This allows device drivers to enable MSI (Message Signaled
10 Interrupts). Message Signaled Interrupts enable a device to
11 generate an interrupt using an inbound Memory Write on its
12 PCI bus instead of asserting a device IRQ pin.

20 This feature enables a procfs file -- /proc/pci -- that provides a
21 summary of PCI devices in the system.

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.

37 Say Y here if you want the PCI core to produce a bunch of debug
38 messages to the system log. Select this if you are having a
39 problem with PCI support and want to see more of what is going on.
