| This allows device drivers to enable MSI (Message Signaled | |
| Interrupts). Message Signaled Interrupts enable a device to | |
| generate an interrupt using an inbound Memory Write on its | |
| PCI bus instead of asserting a device IRQ pin. | |
| Use of PCI MSI interrupts can be disabled at kernel boot time | |
| by using the 'pci=nomsi' option. This disables MSI for the | |
| entire system. | |
| If you don't know what to do here, say N. | |

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