	help
	   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.

	   If you don't know what to do here, say N.

config PCI_DEBUG
	bool "PCI Debugging"
	depends on PCI && DEBUG_KERNEL
	help
	  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.
