[$] BTF, Rust, and the kernel toolchain <a href="https://www.kernel.org/doc/html/latest/bpf/btf.html" rel="nofollow"> BPF Type Format</a> (BTF), BPF's debugging information format, has undergone rapid evolution to match the evolving needs of BPF programs. José Marchesi spoke at Kangrejos about some of that work — and how it could impact Rust, specifically. He discussed debug information, kernel-specific relocations, and the planned changes to kernel stack unwinding. Each of these will require some amount of work to fully support in Rust, but preliminary signs look promising. https://lwn.net/Articles/991719/
