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.
