config PCI_USE_VECTOR
	bool "Vector-based interrupt indexing (MSI)"
	depends on (X86_LOCAL_APIC && X86_IO_APIC) || IA64
	default n
	help
	   This replaces the current existing IRQ-based index interrupt scheme
	   with the vector-base index scheme. The advantages of vector base
	   over IRQ base are listed below:
	   1) Support MSI implementation.
	   2) Support future IOxAPIC hotplug

	   Note that this allows the device drivers to enable MSI, Message
	   Signaled Interrupt, on all MSI capable device functions detected.
	   Message Signal Interrupt enables an MSI-capable hardware device to
	   send an inbound Memory Write on its PCI bus instead of asserting
	   IRQ signal on device IRQ pin.

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

config PCI_LEGACY_PROC
	bool "Legacy /proc/pci interface"
	depends on PCI
	---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 Documentation/Changes for information on where to get the latest 
	  version. 

	  When in doubt, say N.

config PCI_NAMES
	bool "PCI device name database"
	depends on PCI
	---help---
	  By default, the kernel contains a database of all known PCI device
	  names to make the information in /proc/pci, /proc/ioports and
	  similar files comprehensible to the user. 

	  This database increases size of the kernel image by about 80KB. This 
	  memory is freed after the system boots up if CONFIG_HOTPLUG is not set.

	  Anyway, if you are building an installation floppy or kernel for an 
	  embedded system where kernel image size really matters, you can disable 
	  this feature and you'll get device ID numbers instead of names.

	  When in doubt, say Y.
