| 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. |
