The Yocto Project aims to simplify the task of building an embedded Linux distribution. Having evolved from Open Embedded, the Yocto Project provides additional tools and meta data which take a lot of the frustration out of building a distribution up from nothing but recipes. The Yocto Project Linux kernel recipes offer some particular advantages over the traditional defconfig-and-patch-series approach. With a hierarchical branching scheme, the linux-yocto sources allow for fixes, features, and configuration fragments to be shared across board support packages. Features can be trivial or complex out-of-tree patch series like preempt_rt. This allows Yocto to be a vehicle for leading edge technology, while providing a high level of configurability to the developer. This presentation will elaborate on these topics and share some real-world use-cases where the Yocto Project is being put to the test.
