CONFIG_HOTPLUG_PCI: Support for PCI Hotplug

General informations

The Linux kernel configuration item CONFIG_HOTPLUG_PCI has multiple definitions:

Support for PCI Hotplug (EXPERIMENTAL) found in drivers/pci/hotplug/Kconfig

The configuration item CONFIG_HOTPLUG_PCI:

• prompt: Support for PCI Hotplug (EXPERIMENTAL)
• type: tristate
• depends on: CONFIG_PCI && CONFIG_EXPERIMENTAL
• defined in drivers/pci/hotplug/Kconfig
• found in Linux kernels: 2.6.0–2.6.24
• modules built: pci_hotplug

Help text

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.
