When this config option is disabled, this patchset has no effect on the platform. This option is disabled by default. The dependency list assures consistent behavior among CPU, memory and container hotplug operations with regarding the _OST support. Some platforms may require the OS to support _OST in order to support ACPI hotplug operations. For example, if a platform has the management console where user can request a hotplug operation from, this _OST support would be required for the management console to show the result of the hotplug request to user. ACPI PCI hotplug is not enhanced to support _OST at this time since it is a legacy method being replaced by PCI native hotplug. _OST support for ACPI PCI hotplug may be added in future if necessary.
