ACPI on ARM64: Challenges Ahead - Sudeep Holla, ARM

Sign up or log in to save this to your schedule and see who's attending!

ACPI support on ARM64 is merged for v4.1 release and it's just the beginning of the journey. ACPI is a very complex specification and supporting it on ARM requires discipline in many areas. One such area is the ACPI development itself which so far is mostly x86 driven and more aligned to it. There are few areas in the current ACPI support in Linux that can be improved to make it more architecture agnostic. Another area is the firmware development supporting ACPI especially by ARM vendors for whom this is completely new area. Getting those firmware well tested is the main challenge. Given the growing interest in ACPI in ARM ecosystem, steps need to be taken to enforce standardization. This talk highlights these topics by providing a detailed overview of ACPI support on ARM64 with code examples used as a starting point to present the current solution and possible extensions.
