AI Made A Lot Of "Hideous" Code But Found Major Bottlenecks For Faster Linux Compilation
ARM engineer and longtime Linux developer Lorenzo Stoakes submitted a set of 23 patches aimed at significantly speeding up Linux kernel build times by removing single-threaded bottlenecks. Results show full builds up to 36% faster, incremental builds up to 70% faster, and noop builds up to ~90% faster. Stoakes used an LLM to identify bottlenecks and generate initial code, describing much of the generated code as 'hideous' and requiring extensive manual auditing and rewriting. The LLM also helped orchestrate build runs, testing, and debugging, with each commit carrying an Assisted-by tag. Affected subsystems include Kbuild, kallsyms, modpost, objtool, mksysmap, and the Rust build system. The patches are pending review before potential inclusion in mainline Linux.
