对于BIOS来说，Spec规定由BIOS负责将处理器和系统的其他部分初始化到一个已知的状态，并且要负责创建包含MP Configurationd的数据结构，并把这个数据结构传递给OS。

The MultiProcessor Specification, hereafter known as the “MP specification,” defines an enhancement to the standard to which PC manufacturers design DOS-compatible systems. MP-capable operating systems will be able to run without special customization on multiprocessor

The MultiProcessor Specification (MPS) for the x86 architecture is an open standard describing enhancements to both operating systems and firmware, which will allow them to work with x86-compatible processors in a multi-processor configuration.

操作系统有两种获取处理器信息的方式：一种是Intel的MultiProcessor Specification（后续简称MP Spec）约定的方式；另外一种是ACPI MADT（Multiple APIC Description Table）约定的方式。 MP Spec约定的核心数据结构包括两部分：MP Floating Pointer Structure（后续简称MPF）和MP Configuration Table（后续简称MP Table）的地址，如图1-6所示。 处理器的信息记录于MP Table，MP Table包含多个entry，entry分为不同的类型，有的entry是描述处理器信息的，有 …

The MultiProcessor Specification, hereafter known as the “MP specification,” defines an enhancement to the standard to which PC manufacturers design DOS-compatible systems. MP-capable operating systems will be able to run without special customization on multiprocessor systems that comply with this specification.

2017年8月10日 · 本文详细介绍了Inter MultiProcessor规范v1.4中的多核CPU启动机制，包括MP Floating Pointer Structure、MP Configuration Table及其各个组件如Processor Entries、Bus Entries、I/O APIC Entries等，阐述了操作系统如何获取和处理多核启动信息。

The MP specification is designed to make multiprocessing OEM independent. This allows OS support without an OEM driver. Therefore, it makes multiprocessing and all it's problems open to the hobbyist. it is aimed at X86. Please note that X86 multiprocessing is strictly SMP. MP is implemented as PC-AT compatible.

The MP specification provides two methods for passing this information to the operating system: a minimal method for configurations that conform to one of a set of common hardware defaults, and a maximal method that provides the utmost flexibility in hardware design.

2018年2月28日 · MP Spec即MultiProcessor Specification，简称MPS，中文翻译为多重处理器规范，定义了MP系统配置的数据结构。 BIOS构建MP配置数据结构，将硬件以已知格式呈现给标准设备驱动程序或操作系统的硬件抽象层。

Intel MP规范是多处理器系统设计的关键指南，它定义了硬件和软件之间的接口，以确保操作系统的兼容性和可移植性，同时明确了知识产权和责任问题，为业界提供了明确的规则和指导。
