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.

- ---help---
- This feature enables a procfs file -- /proc/pci -- that provides a
- summary of PCI devices in the system.
-
- This feature has been deprecated as of v2.5.53, in favor of using the
- tool lspci(8). This feature may be removed at a future date.
-
- lspci can provide the same data, as well as much more. lspci is a part of
- the pci-utils package, which should be installed by your distribution.
- See <file:Documentation/Changes> for information on where to get the latest
- version.
+ 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.
- When in doubt, say N.
