The OpenEmbedded-Core metadata collection provides the engine of the Poky build tool. It is designed to provide the core features and to be as lean as possible. It provides support for seven different processor architectures (ARM, ARM64, x86, x86-64, PowerPC, MIPS, and MIPS64), supporting only boards to be emulated by QEMU.
The development is centralized in the openembedded-core@lists.openembedded.org mailing list and houses its metadata inside the meta subdirectory of Poky.
