x86_unplug

Description

The methods of the interface are intended to be used by a platform to unplug (and optionally re-plug) CPU cores/threads, effectively hiding them from the #RESET/INIT signals.

This interface is internal and may change without notice.

The unplug_core method is to disable an operating core with all threads on it. The replug_core method is to enable a core previously unplugged with all threads on it. The disable_ht_package method is to disable every secondary thread. The enable_ht_package method is to enable every secondary thread.

Values returned from these methods indicate success (1) or failure (0).
