From C to Rust: Bringing Rust Abstractions to Embedded Linux
summary
Linux v6.0 provides only Linux v6.0 minimal Rust support so Rust can build modules but not kernel frameworks; the work actually implements regulator and DSi panel drivers using the rmap field API, platform, i2c and regulator abstractions, with the goal of landing small, minimally dependent drivers upstream. Development shows Rust shortens code and forces error handling but reveals real problems: ownership and move semantics cause a crash when C-initialized linked lists are moved, and GCC RS / unstable Rust features block broader framework use.
