The Road Towards a Linux TSN Infrastructure
summary
Implemented Linux interfaces for TSN: use mqprio to expose hardware queues, a CBS qdisc for credit‑based shaping and a TBS qdisc plus a TXTIME socket option for per‑packet transmit timestamps. Each qdisc supports hardware offload and a software fallback; pure software scheduling shows worst‑case delays near 1 ms while hardware offload with sorting yields peak jitter around 506 ns in tests. Upstream work is merged for CBS, TBS is near final, and qbv/qbu support and low‑latency data paths remain outstanding.
