Explore the development and potential of Sound Open Firmware in this conference talk by Liam Girdwood from Intel. Dive into the journey of transforming a one-person project for Minnowboard into a multi-product, multi-vendor open-source initiative aiming to become the "Linux" of audio DSP firmware. Gain insights into the technical features that give users an edge over traditional audio solutions and learn about the challenges of transitioning closed firmware and hardware to the open-source world. Discover the SDK's capabilities, including containerization, tool flexibility, and heterogeneous virtualization. Understand the firmware and driver architectures, pipeline structure, and continuous integration processes. Examine SOF platforms, processing components, and future plans while considering the broader implications for open-source firmware in other subsystems.
