Firmware Sleep State Orchestration for Heterogeneous Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Management of firmware within Information Handling Systems (IHS) is typically performed indirectly through the OS, leading to efficiency, productivity, and security issues.
Innovation Solution
A firmware framework that includes a controller to receive requests from the OS to enter a sleep state, determine the specified sleep state level for each device, and communicate with devices to place them at that level, reducing OS dependency and enhancing management efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If firmware management is performed indirectly through the OS, then the OS can provide high-level abstraction and ease of use, but system efficiency decreases and security issues arise
Solution Approach 1:
The patent introduces a firmware management module as an intermediary layer between the OS and firmware. This module receives high-level commands from the OS and translates them into device-specific firmware operations, maintaining ease of use while improving efficiency by providing direct firmware control paths.
Solution Approach 2:
The firmware management functionality is segmented into distinct components: the OS layer for high-level coordination, the firmware management module for translation and coordination, and device-specific firmware layers for execution. This segmentation allows each layer to operate optimally without the inefficiencies of indirect communication throughout the entire stack.
2Ease of operation
If firmware management is performed indirectly through the OS, then centralized control is maintained, but security vulnerabilities increase
Solution Approach 1:
The firmware management module serves as a security intermediary that validates and verifies firmware operations before execution. It implements security policies, verifies firmware integrity, and controls access to firmware updates, maintaining centralized authorization while preventing security vulnerabilities through layered verification.
Solution Approach 2:
The system performs preliminary security checks including firmware verification, authentication, and policy validation before executing firmware operations. This preliminary action ensures that only authorized and verified firmware changes are applied, preventing security issues before they can manifest.
3Adaptability or versatility
If the system uses heterogeneous computing platforms with multiple devices, then functionality and versatility increase, but coordination complexity during state transitions increases
Solution Approach 1:
The firmware management module implements universal coordination mechanisms that work across heterogeneous devices. It provides standardized interfaces and unified state transition protocols that can manage diverse device types (display, audio, communication, etc.) through common procedures, reducing coordination complexity despite functional diversity.
Solution Approach 2:
Before initiating state transitions, the system performs preliminary coordination among all affected devices. The firmware management module identifies all devices that need to transition, prepares their respective firmware states, and coordinates the timing of transitions to ensure system-wide consistency, thereby simplifying the complexity of managing heterogeneous devices.

AI summary
Systems and methods for discovery in a firmware framework are described. In an illustrative, non-limiting embodiment, an Information Handling System (IHS) may include a heterogeneous computing platform with multiple devices, and a controller configured with firmware that, upon execution by a processing core, causes the processing core to receive a request from an Operating System (OS) to enter a sleep state, determine, for each of the plurality of devices, a specified sleep state level for the device, and communicate with each of the devices to place the device at the specified sleep state level.
