Static partitioning enables multiple domains to run alongside each other with no interference. They could be running Linux, an RTOS, or another OS, and all of them have direct access to different portions of the SoC. In the last five years, the Xen community introduced several new features to make Xen-based static partitioning possible. Dom0less to start multiple static domains in parallel at boot, and Cache Coloring to minimize cache interference effects are among them. Static inter-domain communications mechanisms were introduced this year, while "ImageBuilder" has been making system-wide configurations easier. An easy-to-use complete solution is within our grasp. This talk will show the progress made on Xen static partitioning. The audience will learn to configure a realistic reference design with multiple partitions: a LinuxRT partition, a Zephyr partition, and a larger Linux partition. The presentation will show how to set up communication channels and direct hardware access for the domains. It will explain how to measure interrupt latency and use cache coloring to zero cache interference effects. The talk will include a live demo of the reference design.
