/** @file When installed, the Framework MP Services Protocol produces a collection of services that are needed for MP management, such as initialization and management of application processors. @par Note: This protocol has been deprecated and has been replaced by the MP Services Protocol from the UEFI Platform Initialization Specification 1.2, Volume 2: Driver Execution Environment Core Interface. The MP Services Protocol provides a generalized way of performing following tasks: - Retrieving information of multi-processor environment and MP-related status of specific processors. - Dispatching user-provided function to APs. - Maintain MP-related processor status. The MP Services Protocol must be produced on any system with more than one logical processor. The Protocol is available only during boot time. MP Services Protocol is hardware-independent. Most of the logic of this protocol is architecturally neutral. It abstracts the multi-processor environment and status of processors, and provides interfaces to retrieve information, maintain, and dispatch. MP Services Protocol may be consumed by ACPI module. The ACPI module may use this protocol to retrieve data that are needed for an MP platform and report them to OS. MP Services Protocol may also be used to program and configure processors, such as MTRR synchronization for memory space attributes setting in DXE Services. MP Services Protocol may be used by non-CPU DXE drivers to speed up platform boot by taking advantage of the processing capabilities of the APs, for example, using APs to help test system memory in parallel with other device initialization. Diagnostics applications may also use this protocol for multi-processor. Copyright (c) 1999 - 2010, Intel Corporation.
