This advanced tutorial shows how to build a custom Linux kernel using the Yocto Project kernel tooling, which includes the linux-yocto repository with mainline source and configuration metadata. It discusses the 2 most common methods of managing kernel configuration and BSP patches. First, we create a BSP using the upstream mainline kernel with local patches and defconfig. Then, we create a new BSP with linux-yocto style metadata and explain some of the advantages of this method. The talk follows the process of creating a complete kernel config file and then moving to break it down to config fragments that can be pushed upstream to the linux-yocto repository for all to use, and also includes hints and suggestions on kernel configuration debugging
