menuconfig HOTPLUG_PCI
bool "Support for PCI Hotplug"
depends on PCI && SYSFS
default y if USB4
help
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.
Thunderbolt/USB4 PCIe tunneling depends on native PCIe hotplug.
When in doubt, say N.

help
Say Y here if you have a motherboard with a Compaq PCI Hotplug
controller.
To compile this driver as a module, choose M here: the
module will be called cpqphp.
When in doubt, say N.
config HOTPLUG_PCI_COMPAQ_NVRAM
bool "Save configuration into NVRAM on Compaq servers"
depends on HOTPLUG_PCI_COMPAQ
help
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.
