-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.
+ Use of PCI MSI interrupts can be disabled at kernel boot time
+ by using the 'pci=nomsi' option. This disables MSI for the
+ entire 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.
+ If you don't know what to do here, say N.
- 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.
+config PCI_MULTITHREAD_PROBE
+ bool "PCI Multi-threaded probe (EXPERIMENTAL)"
+ depends on PCI && EXPERIMENTAL
+ help
+ Say Y here if you want the PCI core to spawn a new thread for
+ every PCI device that is probed. This can cause a huge
+ speedup in boot times on multiprocessor machines, and even a
+ smaller speedup on single processor machines.
+
+ But it can also cause lots of bad things to happen. A number
+ of PCI drivers can not properly handle running in this way,
+ some will just not work properly at all, while others might
+ decide to blow up power supplies with a huge load all at once,
+ so use this option at your own risk.
+
+ It is very unwise to use this option if you are not using a
+ boot process that can handle devices being created in any
+ order. A program that can create persistant block and network
+ device names (like udev) is a good idea if you wish to use
+ this option.
+
+ Again, use this option at your own risk, you have been warned!
When in doubt, say N.
