This patch forwards environment variables to control the concurrency and parallelism of the build to bitbake. With that, the user can reduce the concurrency in case of running short on memory. Further, by reducing the concurrency on very large and NUMA machines, the build sometimes can be significantly speed up.

Setup tool for bitbake based projects ===================================== +--------------------+ | Build Status | +====================+ | |workflow-master|_ | +--------------------+ | |workflow-next|_ | +--------------------+ .. |workflow-master| image:: https://github.com/siemens/kas/workflows/master/badge.svg .. _workflow-master: https://github.com/siemens/kas/actions?query=workflow%3Amaster .. |workflow-next| image:: https://github.com/siemens/kas/workflows/next/badge.svg .. _workflow-next: https://github.com/siemens/kas/actions?query=workflow%3Anext This tool provides an easy mechanism to setup bitbake based projects. The OpenEmbedded tooling support starts at step 2 with bitbake. The downloading of sources and then configuration has to be done by hand. Usually, this is explained in a README. Instead kas is using a project configuration file and does the download and configuration phase. Key features provided by the build tool: - clone and checkout bitbake layers - create default bitbake settings (machine, arch, ...) - launch minimal build environment, reducing risk of host contamination - initiate bitbake build process See the `kas documentation <https://kas.readthedocs.io>`_ for further details.
