Unlike earlier versions that required proprietary APIs, VxWorks 21.11 deepens its POSIX PSE52 (Real-time Controller) compliance. This allows developers to port Linux applications to VxWorks with minimal refactoring, reducing time-to-market for mixed-criticality systems.

While VxWorks has supported containers since VxWorks 7, 21.11 brings compliance. Developers can now build a container on a Linux host using Docker/Podman, push it to a registry, and execute it on VxWorks using the vxcontainerd runtime. This is revolutionary for edge computing scenarios where Linux is too heavy or non-deterministic.

: Unlike Linux, VxWorks allows applications to manipulate hardware by writing directly to device registers. 4. Getting Started Resources

Wind River’s internal benchmarks (published in white paper WP-21.11-001) demonstrate the leap:

While Linux PREEMPT_RT is excellent for soft real-time (audio, robotics), VxWorks 21.11 remains the choice for systems where missing a deadline causes physical damage or loss of life.
