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.

+ This feature enables a procfs file -- /proc/pci -- that provides a

+ 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
