Red Hat In-Vehicle Operating System is a safety-certified Linux platform designed for software-defined vehicles, enabling safety-critical and non-safety applications to run on a single ASIL-B certified kernel. Using containerization, logical partitioning, and Linux isolation mechanisms such as namespaces, cgroups, SELinux, and PREEMPT_RT scheduling, it ensures spatial and temporal isolation without the overhead of multiple guest operating systems. This unified architecture reduces complexity, startup time, and memory footprint while meeting ISO 26262 functional safety requirements.
