ACPI Pre-Boot Health Telemetry With Dynamic Parser Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing Information Handling Systems (IHS) face challenges in handling platform-agnostic pre-boot health information due to the diversity of BIOS/UEFI implementations across different processor types, leading to inconsistencies in ACPI table formats and parser compatibility.
Innovation Solution
The system creates an ACPI table during boot that includes telemetry data and an identifier, allowing the Operating System (OS) to select the appropriate parser based on the processor type, model, or vendor, ensuring compatibility across various platforms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a unified ACPI table format is used across all processor platforms, then ease of operation is improved, but manufacturing precision deteriorates due to platform-specific format requirements
Solution Approach 1:
The ACPI table format is segmented into a universal portion (containing common health information structures) and platform-specific portions (identified by vendor IDs and processor type identifiers). This segmentation allows the OS to select appropriate parsing methods for different platforms while maintaining a consistent base structure, thereby improving ease of operation without sacrificing manufacturing precision for platform-specific requirements
Solution Approach 2:
The ACPI table is designed with universal elements that can be processed by any platform, including standardized health information fields and a vendor ID field that enables platform identification. This universality allows the same ACPI table structure to serve multiple processor platforms (x86, ARM, RISC) while maintaining platform-specific precision through the identifier fields
2Manufacturing precision
If platform-specific parsers are used for each processor type, then manufacturing precision is improved, but device complexity increases due to multiple parser implementations
Solution Approach 1:
The parser selection is made dynamic rather than static - the OS application dynamically selects the appropriate parser based on the processor type identifier and vendor ID found in the ACPI table. This dynamic selection mechanism allows the system to maintain platform-specific precision while presenting a unified interface to users, effectively managing device complexity through runtime adaptation
Solution Approach 2:
The ACPI table serves as an intermediary structure that contains platform identification information (vendor ID, processor type fields) which mediates between the platform-specific BIOS/UEFI implementation and the OS parser selection logic. This intermediary enables automatic parser selection without requiring hard-coded platform-specific logic throughout the system, thereby managing complexity while maintaining precision
3Adaptability or versatility
If an identifier field is added to the ACPI table to enable parser selection, then adaptability is improved, but device complexity increases due to additional data structures
Solution Approach 1:
The vendor ID field and processor type identifier fields in the ACPI table serve multiple functions: they enable parser selection for adaptability, provides platform identification for debugging and logging, and maintain backward compatibility with existing ACPI table structures. This multi-functionality justifies the additional data structure elements by providing multiple benefits beyond just parser selection
Solution Approach 2:
The ACPI table structure is extended with specific parameter fields (vendor ID, processor type identifier) that change based on the platform. These parameter changes enable the system to adapt to different processor types (x86, ARM, RISC) while maintaining a consistent overall table structure, thereby improving adaptability without significantly increasing complexity

AI summary
Systems and methods for handling platform-agnostic pre-boot health information in an Information Handling System (IHS) are described. In an illustrative, non-limiting embodiment, an IHS may include a processor; and a memory coupled to the processor, the memory having program instructions stored thereon that, upon execution, cause the IHS to: create an Advanced Configuration and Power Interface (ACPI) table, by a Basic Input/Output System (BIOS) during boot of the IHS, wherein the ACPI table comprises telemetry data and an identifier; and provide the ACPI table to an Operating System (OS) application, wherein the host OS application is configured to select one of a plurality of parsers to process the ACPI table based, at least in part, upon the identifier.
