   4 config PCI_MSI
   5         bool "Message Signaled Interrupts (MSI and MSI-X)"
   6         depends on PCI
   7         depends on (X86_LOCAL_APIC && X86_IO_APIC) || IA64
   8         help
   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
  14            If you don't know what to do here, say N.
  15
  16 config PCI_LEGACY_PROC
  17         bool "Legacy /proc/pci interface"
  18         depends on PCI
  19         ---help---
  20           This feature enables a procfs file -- /proc/pci -- that provides a
  21           summary of PCI devices in the system.
  22
  23           This feature has been deprecated as of v2.5.53, in favor of using the
  24           tool lspci(8). This feature may be removed at a future date.
  25
  26           lspci can provide the same data, as well as much more. lspci is a part of
  27           the pci-utils package, which should be installed by your distribution.
  28           See <file:Documentation/Changes> for information on where to get the latest
  29           version.
  30
  31           When in doubt, say N.
  32
  33 config PCI_NAMES
  34         bool "PCI device name database"
  35         depends on PCI
  36         ---help---
  37           By default, the kernel contains a database of all known PCI device
  38           names to make the information in /proc/pci, /proc/ioports and
  39           similar files comprehensible to the user.
  40
  41           This database increases size of the kernel image by about 80KB. This
  42           memory is freed after the system boots up if CONFIG_HOTPLUG is not set.
  43
  44           Anyway, if you are building an installation floppy or kernel for an
  45           embedded system where kernel image size really matters, you can disable
  46           this feature and you'll get device ID numbers instead of names.
  47
  48           When in doubt, say Y.
  49
  50 config PCI_DEBUG
  51         bool "PCI Debugging"
  52         depends on PCI && DEBUG_KERNEL
  53         help
  54           Say Y here if you want the PCI core to produce a bunch of debug
  55           messages to the system log.  Select this if you are having a
  56           problem with PCI support and want to see more of what is going on.
  57
  58           When in doubt, say N.
