Explore toolchain-agnostic methods to enhance Linux kernel compile and build times in this 23-minute conference talk from the Linux Plumbers Conference. Delve into various research areas presented by Google engineers Tanzir Hasan and Nick Desaulniers, including Ingo's "Fast Kernel Headers" series, automated header refactoring techniques, and the application of include-what-you-use to the Linux kernel. Learn about the potential of precompiled headers, recent enhancements to modpost, and link-time de-duplication of BTF. Gain insights into cutting-edge approaches aimed at optimizing the Linux kernel development process, regardless of the toolchain in use.
