are all schedulers going to run in userspace? E.g. we still have EDF and it's still used by, e.g. kpb. As long as the privileged mode uses this, seems rather risky to me to let userspace overwrite it.

@lyakh That is the goal. This does leave a gap currently with EDF. Ideally, the SOF schedule.h will only handle audio application logic (how to schedule audio pipelines), while the lower level scheduling is moved to Zephyr. We do have some remaining work to do, especially with EDF used for IPC task.
