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.

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

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 <file:Documentation/Changes> for information on where to get the latest
|
||
|
|
version.
|

When in doubt, say N.

---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.

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.
