5 bool "Message Signaled Interrupts (MSI and MSI-X)"
6 depends on (X86_LOCAL_APIC && X86_IO_APIC) || IA64
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.
14 If you don't know what to do here, say N.
16 config PCI_LEGACY_PROC
17 bool "Legacy /proc/pci interface"
20 This feature enables a procfs file -- /proc/pci -- that provides a
21 summary of PCI devices in the system.
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.
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.

34 bool "PCI device name database"
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.
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.
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.
