What makes AutoSD different?¶

AutoSD addresses the unique challenges of automotive computing:

Mixed criticality architecture : Run safety-critical and non-critical workloads on the same platform with proven isolation using containers and partitioning.

Real-time performance : Optimized kernel-automotive with Real-Time Linux, deterministic scheduling, and minimal latency for time-critical applications.

Reliable updates : OSTree-based immutable images with atomic A/B updates, rollback capabilities, and bandwidth-efficient delta updates.

Container-native : Built for containerized applications with Quadlet, systemd integration, and seamless orchestration with BlueChi.

Developer-friendly : Complete toolchain with Automotive Image Builder, comprehensive manifests, and configurations for various hardware platforms.

Popular use cases¶
