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. | |

19 | ---help--- | |
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. | |

31 | When in doubt, say N. | |

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. | |
