Description: Message Signaled Interrupts (MSI and MSI-X)

More info: 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 Y.
