Hypervisors are key to enable mixed-criticality systems: a critical workload, typically with real-time requirements, running alongside a larger operating system, such as Linux. The interrupt latency needs to be deterministic, and the boot time of the critical function only a fraction of a second. Hypervisors are also the enabling technology to securely deploy new customers apps at runtime, without affecting system safety.
This presentation will give an overview of hypervisor technologies for Xilinx platforms. It will introduce the most recent developments of the Xen hypervisor, including the "null" scheduler and dom0less, and it will explain how to make use of the new features to best configure Xen for embedded environments.
