9	depends on PCI && EXPERIMENTAL
10	select HOTPLUG
11	---help---
12	  Say Y here if you have a motherboard with a PCI Hotplug controller.
13	  This allows you to add and remove PCI cards while the machine is
14	  powered up and running.
15
16	  To compile this driver as a module, choose M here: the
17	  module will be called pci_hotplug.

19	  When in doubt, say N.

21config HOTPLUG_PCI_FAKE
22	tristate "Fake PCI Hotplug driver"
23	depends on HOTPLUG_PCI
24	help
25	  Say Y here if you want to use the fake PCI hotplug driver. It can
26	  be used to simulate PCI hotplug events if even if your system is
27	  not PCI hotplug capable.
28
29	  This driver will "emulate" removing PCI devices from the system.
30	  If the "power" file is written to with "0" then the specified PCI
31	  device will be completely removed from the kernel.
32
33	  WARNING, this does NOT turn off the power to the PCI device.
34	  This is a "logical" removal, not a physical or electrical
35	  removal.
36
37	  Use this module at your own risk.  You have been warned!
