The GSRD build process relies on several git trees that are available online, including:

Intel SoC FPGA Linux designs

Intel SoC FPGA Angstrom recipes
Note: Intel® provides Linux* enablement, upstreams to mainline and collaborates with the Linux* community. Intel® provides two kernel versions, the latest stable kernel (N) and latest LTSI kernel (M) and drops support for previous Linux* kernel versions (N-1, M-1). At any point in time the (N, N-1, M, M-1) versions are available from the kernel repository. Older kernel versions are removed.

GUIDELINE: Manage your own Git repositories and do not assume the contents of the repositories available on the altera-opensource site remains available. Managing Git repositories can be achieved in many ways, such as using a Git service provider. Some benefits of managing your own Git repositories include build reproducibility, source code management and leveraging the distributed model enabled by Git.

The GSRD uses the Angstrom rootfilesystem, built using Yocto recipes. The recipes pull in various open source package sources, and build them into the rootfilesystem. Because some of these recipes are generic, and do not refer to a specific version, the end result may be different from one build to another.

GUIDELINE: If you rebuild the Angstrom rootfilesystem and require repeatability, you must keep a copy of the Yocto downloads folder that was used for the build.
