  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. Use of PCI MSI interrupts can be disabled at kernel boot time
  14. by using the 'pci=nomsi' option. This disables MSI for the
  15. entire system.
  16. If you don't know what to do here, say N.

  21. Say Y here if you want the PCI core to produce a bunch of debug
  22. messages to the system log. Select this if you are having a
  23. problem with PCI support and want to see more of what is going on.
  24. When in doubt, say N.
