 * PCI Hotplug support

PCI Hotplug Support

 * Option: HOTPLUG_PCI
 * Kernel Versions: 2.6.15.6 ...
 * (on/off/module) Support for PCI Hotplug (EXPERIMENTAL)
 * depends on PCI && EXPERIMENTAL
 * select HOTPLUG
 * Say Y here if you have a motherboard with a PCI Hotplug controller. This allows you to add and remove PCI cards while the machine is powered up and running. The file system pcihpfs must be mounted in order to interact with any PCI Hotplug controllers.
 * To compile this driver as a module, choose M here: the module will be called pci_hotplug.
 * When in doubt, say N.


 * Option: HOTPLUG_PCI_FAKE
 * Kernel Versions: 2.6.15.6 ...
 * (on/off/module) Fake PCI Hotplug driver
 * depends on HOTPLUG_PCI
 * Say Y here if you want to use the fake PCI hotplug driver. It can be used to simulate PCI hotplug events if even if your system is not PCI hotplug capable.
 * This driver will "emulate" removing PCI devices from the system. If the "power" file is written to with "0" then the specified PCI device will be completely removed from the kernel.
 * WARNING, this does NOT turn off the power to the PCI device. This is a "logical" removal, not a physical or electrical removal.
 * Use this module at your own risk. You have been warned!
 * To compile this driver as a module, choose M here: the module will be called fakephp.
 * When in doubt, say N.


 * Option: HOTPLUG_PCI_COMPAQ
 * Kernel Versions: 2.6.15.6 ...
 * (on/off/module) Compaq PCI Hotplug driver
 * depends on HOTPLUG_PCI && X86 && PCI_BIOS
 * Say Y here if you have a motherboard with a Compaq PCI Hotplug controller.

 * When in doubt, say N.


 * Option: HOTPLUG_PCI_COMPAQ_NVRAM

 * depends on HOTPLUG_PCI_COMPAQ
 * Say Y here if you have a Compaq server that has a PCI Hotplug controller. This will allow the PCI Hotplug driver to store the PCI system configuration options in NVRAM.
 * When in doubt, say N.


 * Option: HOTPLUG_PCI_IBM
 * Kernel Versions: 2.6.15.6 ...
 * (on/off/module) IBM PCI Hotplug driver

 * When in doubt, say N.


 * Option: HOTPLUG_PCI_ACPI
 * Kernel Versions: 2.6.15.6 ...
 * (on/off/module) ACPI PCI Hotplug driver
 * depends on ACPI && HOTPLUG_PCI
 * Say Y here if you have a system that supports PCI Hotplug using ACPI.

 * When in doubt, say N.


 * Option: HOTPLUG_PCI_ACPI_IBM
 * Kernel Versions: 2.6.15.6 ...
 * (on/off/module) ACPI PCI Hotplug driver IBM extensions
 * depends on HOTPLUG_PCI_ACPI
 * Say Y here if you have an IBM system that supports PCI Hotplug using ACPI.
 * To compile this driver as a module, choose M here: the module will be called acpiphp_ibm.
 * When in doubt, say N.


 * Option: HOTPLUG_PCI_CPCI
 * Kernel Versions: 2.6.15.6 ...
 * (on/off) CompactPCI Hotplug driver
 * depends on HOTPLUG_PCI
 * Say Y here if you have a CompactPCI system card with CompactPCI hotswap support per the PICMG 2.1 specification.
 * When in doubt, say N.


 * Option: HOTPLUG_PCI_CPCI_ZT5550
 * Kernel Versions: 2.6.15.6 ...
 * (on/off/module) Ziatech ZT5550 CompactPCI Hotplug driver
 * depends on HOTPLUG_PCI && HOTPLUG_PCI_CPCI && X86
 * Say Y here if you have an Performance Technologies (formerly Intel,        formerly just Ziatech) Ziatech ZT5550 CompactPCI system card.
 * To compile this driver as a module, choose M here: the module will be called cpcihp_zt5550.
 * When in doubt, say N.


 * Option: HOTPLUG_PCI_CPCI_GENERIC
 * Kernel Versions: 2.6.15.6 ...
 * (on/off/module) Generic port I/O CompactPCI Hotplug driver
 * depends on HOTPLUG_PCI && HOTPLUG_PCI_CPCI && X86
 * Say Y here if you have a CompactPCI system card that exposes the #ENUM hotswap signal as a bit in a system register that can be read through standard port I/O.
 * To compile this driver as a module, choose M here: the module will be called cpcihp_generic.
 * When in doubt, say N.


 * Option: HOTPLUG_PCI_SHPC
 * Kernel Versions: 2.6.15.6 ...
 * (on/off/module) SHPC PCI Hotplug driver
 * depends on HOTPLUG_PCI
 * Say Y here if you have a motherboard with a SHPC PCI Hotplug controller.
 * To compile this driver as a module, choose M here: the module will be called shpchp.
 * When in doubt, say N.


 * Option: HOTPLUG_PCI_SHPC_POLL_EVENT_MODE
 * Kernel Versions: 2.6.15.6 ...
 * (on/off) Use polling mechanism for hot-plug events (for testing purpose)
 * depends on HOTPLUG_PCI_SHPC
 * Say Y here if you want to use the polling mechanism for hot-plug events for early platform testing.
 * When in doubt, say N.


 * Option: HOTPLUG_PCI_SHPC_PHPRM_LEGACY
 * Kernel Versions: 2.6.15.6 ...
 * (on/off) For AMD SHPC only: Use $HRT for resource/configuration
 * depends on HOTPLUG_PCI_SHPC && !ACPI
 * Say Y here for AMD SHPC. You have to select this option if you are using this driver on platform with AMD SHPC.


 * Option: HOTPLUG_PCI_RPA
