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.
13
14 Use of PCI MSI interrupts can be disabled at kernel boot time
15 by using the 'pci=nomsi' option. This disables MSI for the
16 entire system.

18 If you don't know what to do here, say Y.

25 messages to the system log. Select this if you are having a
26 problem with PCI support and want to see more of what is going on.
