EFI S3 Resume Boot Path Specification v0.9
Overview
This specification defines the core code and services that are
required for an implementation of the S3 resume boot path in the Intel® Platform Innovation Framework for EFI (hereafter
referred to as the “Framework”). The S3 resume boot path is a special boot path that causes the Framework to take actions
different from those in the normal boot path. This specification does the following:
• Describes the basic components of
the S3 resume boot path, how it relates to a normal boot path, and how it interacts with other Framework phases and
code
• Provides code definitions for the S3-related protocols and PPIs that are architecturally required by the Intel®
Platform Innovation Framework for EFI Architecture Specification
Goals
This Framework S3 resume boot path design has
the following goals:
• Extensibility:
The Framework S3 resume boot path should easily adapt to different platforms,
such as Itanium®-based platforms and those based on 32-bit Intel® architecture (IA-32), by replacing only a few platform-
specific modules.
• High performance:
S3 restoration is most commonly used in notebook computers. Its performance is
highly visible to end users.
Requirements
This Framework S3 resume boot path design must meet the following
requirements:
• All aspects of this design must comply with the following:
• Intel® Platform Innovation Framework for
EFI Architecture Specification
• Intel® Platform Innovation Framework for EFI Pre-EFI Initialization Core Interface
Specification (PEI CIS)
• Intel® Platform Innovation Framework for EFI Driver Execution Environment Core Interface
Specification (DXE CIS)
• Advanced Configuration and Power Interface Specification (hereafter referred to as the “ACPI
specification”), revision 2.0
• The design must enable size efficiency, code reuse, and maintainability
