| 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 | Say Y here if you want the PCI core to produce a bunch of debug |
| 21 | messages to the system log. Select this if you are having a |
| 22 | problem with PCI support and want to see more of what is going on. |
