10 This allows device drivers to enable MSI (Message Signaled
11 Interrupts). Message Signaled Interrupts enable a device to
12 generate an interrupt using an inbound Memory Write on its
13 PCI bus instead of asserting a device IRQ pin.
15 If you don't know what to do here, say N.
18 bool "Legacy /proc/pci interface"
19 depends on PCI
20 ---help---
21 This feature enables a procfs file -- /proc/pci -- that provides a
22 summary of PCI devices in the system.
24 This feature has been deprecated as of v2.5.53, in favor of using the
25 tool lspci(8). This feature may be removed at a future date.
27 lspci can provide the same data, as well as much more. lspci is a part of
28 the pci-utils package, which should be installed by your distribution.
29 See <file:Documentation/Changes> for information on where to get the latest
30 version.
32 When in doubt, say N.
34 config PCI_DEBUG
35 bool "PCI Debugging"
36 depends on PCI && DEBUG_KERNEL
37 help
38 Say Y here if you want the PCI core to produce a bunch of debug
39 messages to the system log. Select this if you are having a
40 problem with PCI support and want to see more of what is going on.
42 When in doubt, say N.
