5 bool "Vector-based interrupt indexing (MSI)"
6 depends on (X86_LOCAL_APIC && X86_IO_APIC && !X86_64) || IA64
9 This replaces the current existing IRQ-based index interrupt scheme
10 with the vector-base index scheme. The advantages of vector base
11 over IRQ base are listed below:
12 1) Support MSI implementation.
13 2) Support future IOxAPIC hotplug
15 Note that this allows the device drivers to enable MSI, Message
16 Signaled Interrupt, on all MSI capable device functions detected.
17 Message Signal Interrupt enables an MSI-capable hardware device to
18 send an inbound Memory Write on its PCI bus instead of asserting
19 IRQ signal on device IRQ pin.
21 If you don't know what to do here, say N.
23 config PCI_LEGACY_PROC
24 bool "Legacy /proc/pci interface"
27 This feature enables a procfs file -- /proc/pci -- that provides a
28 summary of PCI devices in the system.
30 This feature has been deprecated as of v2.5.53, in favor of using the
31 tool lspci(8). This feature may be removed at a future date.
33 lspci can provide the same data, as well as much more. lspci is a part of
34 the pci-utils package, which should be installed by your distribution.
35 See Documentation/Changes for information on where to get the latest
41 bool "PCI device name database"
44 By default, the kernel contains a database of all known PCI device
45 names to make the information in /proc/pci, /proc/ioports and
46 similar files comprehensible to the user.
48 This database increases size of the kernel image by about 80KB. This
49 memory is freed after the system boots up if CONFIG_HOTPLUG is not set.
51 Anyway, if you are building an installation floppy or kernel for an
52 embedded system where kernel image size really matters, you can disable
53 this feature and you'll get device ID numbers instead of names.
