Status of Embedded Linux
summary
Kernel land is moving fast: io_uring zero-copy network and an IO_uring-based spawn that cuts fork/exec latency (roughly 6–10× vs vfork, ~30% vs posix_spawn) land alongside embedded conveniences like boot config embedded in images and u-boot HTTP boot. Rust lands as experimental, runtime verification tools (RV) appear, and the slob allocator is removed so tiny builds must switch to SLUB variants. Real‑time inches forward (sleeping spinlocks mainlined, preempt-RT usable), Snagboot recovers bricked boards, and Linux runs on ~50% of cubesats and thousands of Starlink nodes.
