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

20config HOTPLUG_PCI_FAKE
21	tristate "Fake PCI Hotplug driver"
22	depends on HOTPLUG_PCI
23	help
24	  Say Y here if you want to use the fake PCI hotplug driver. It can
25	  be used to simulate PCI hotplug events if even if your system is
26	  not PCI hotplug capable.
27
28	  This driver will "emulate" removing PCI devices from the system.
29	  If the "power" file is written to with "0" then the specified PCI
30	  device will be completely removed from the kernel.
31
32	  WARNING, this does NOT turn off the power to the PCI device.
33	  This is a "logical" removal, not a physical or electrical
34	  removal.
35
36	  Use this module at your own risk.  You have been warned!

60	  controller.  This will allow the PCI Hotplug driver to store the PCI
61	  system configuration options in NVRAM.

63	  When in doubt, say N.
