OSS + ELC EU 2026

Modern SoCs have a variety of CPU cores on board - e.g. on ARM we often see Cortex A, plus Cortex M, plus System Controllers. The number of cores is as increasing as the demands. Concepts like 'Software Defined Vehicle' (SDV) from the automotive sector is just one example for such complex demands. One obvious requirement is to run other OS than Linux on dedicated cores. Which means that resources like memory, clocks, pin control, power domains, etc. may not be under the sole control of Linux anymore. They now need to be shared and synchronized between all the participants. How does this work in practice? How do technologies like remoteproc, rpmsg, mailboxes, hardware spinlocks, virtio, and devicetree come into play here? How is their status-quo? And what about the non-Linux sides? What is open, what is proprietary, and how does this affect actual solutions? This talk is the result of a journey trying to support LinuxZephyr based AMP using a complete FreeSoftware stack on a Renesas community board.
