AI-driven patches could make Linux 7.4 kernel builds 36% faster, with incremental builds seeing up to 70% improvement. This matters for developers looking to streamline their workflow and reduce compile times.
Linux kernel developers may soon enjoy significantly faster build times, thanks to a new series of patches potentially landing in Linux 7.4. Spearheaded by Lorenzo Stoakes of ARM, these patches were submitted to the Linux kernel mailing list and promise to speed up full kernel builds by approximately 36%, while incremental builds could see improvements of up to 70%.
The improvements come from addressing various single-threaded bottlenecks within the kernel's build process. With the help of AI, developers were able to identify and fix what was described as 'hideous code', leading to these impressive performance gains. The second revision of these patches was submitted recently, following some minor fixes and rebasing against the latest upstream Linux Git code.
Two of the original patches have already been merged, while others are still under consideration. Among the changes, the Rust compiler parallel front-end has been made opt-in, which further contributes to the speed-up. Stoakes mentioned that the changes are largely uncontroversial, and there's optimism about their inclusion in the next kernel cycle.
For developers and system administrators, these improvements can translate into more efficient workflows and reduced time waiting for builds to complete. Faster build times mean quicker iterations and testing, which is crucial in a fast-paced development environment.
The patches are currently available for review on the kernel mailing list, and those interested can follow the developments there. If integrated into Linux 7.4, these changes could offer a substantial boost to productivity for anyone involved in kernel development.
