Description
Last year's LPC discussion explored whether ACPI-defined hardware descriptions could be reused on systems booting with Devicetree, and where the boundary should exist between the two firmware ecosystems.
Since then, several related efforts have continued across the kernel community, having intermediate representation for MIPI DISCO tables for SDCA, emerging ACPI-DT hybrid approaches. At the same time, new platform requirements—particularly on ARM64 laptops and embedded systems—continue to challenge the traditional "ACPI or DT" model.
This session will review the current state of these efforts, How should systems without ACPI tables should work with drivers like SDCA, discuss practical use cases where combining ACPI and Devicetree provides value, examine ongoing hybrid firmware work, and identify remaining technical ad architectural challenges. The goal is to gather feedback on whether the community should continue evolving hybrid solutions, standardize common mechanisms, or pursue alternative directions given that we have more data points.
Key Highligths:
- Ongoing efforts.
- Current Status of work on SDCA.
- ACPI-DT hybrid mode and future.
- Systems without ACPI tables(mobile devices).
