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.

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.
