ACPI-Lite: Exploring a Simplified Mechanism for Abstracting Platforms with ACPI

Presented by

Andrei Warkentin (VMware)

About this talk

ACPI has been adopted by 64-bit Arm platforms in the server, edge and even client space. While standardization afforded by abstracting the hardware via ACPI and unification with the x86 ecosystem is positive, there are some obstacles with ACPI. Challenges stem from the size of the specification, heft and requirements on the OS supporting code and limitations of the bytecode itself that may preclude ACPI adoption in the embedded, IoT or safety-critical system space. This talk explores some strategies and approaches in defining a lighter-weight subset of ACPI. The end goal is to support more variance in hardware using less code, less overhead and less engineering time. The goal of the session is not to push a specific proposal, but to get the conversation started to help chart ACPI's future.
