The Xen Safety Concept, a Major Milestone Toward Certification
summary
Xen achieves a concrete milestone: Safety Concept Approval (Q4 2024) from third‑party assessors, committing to ISO 26262 and IEC 61508 certification paths. Work items include making Xen MISRA C compliant (99% MISRA upstream), adding cache‑coloring for hard real‑time, open GitLab CI with physical runners (11 AMD‑hosted plus community runners) for validation, and protocol changes like vertio with grants plus non‑blocking PCI ops; plan is to upstream code and artifacts and execute the remaining verification to reach full certification.
