This patch is the SGI hotplug driver and additional changes required for the driver. These modifications include changes to the SN io_init.c code for memory management, the inclusion of new SAL calls to enable and disable PCI slots, and a hotplug-style driver.

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.

|

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!
