OpenSBI Contribution Guideline

All contributions to OpenSBI can be sent in the following ways:

  1. Email patches to the OpenSBI mailing list at opensbi@lists.infradead.org
  2. GitHub Pull Requests (PRs) to the OpenSBI main repository

To join the OpenSBI mailing list, please visit the OpenSBI infradead page.

The OpenSBI maintainers prefer patches via the OpenSBI mailing list (option 1 above) so that they are visible to a wider audience. All accepted patches on the OpenSBI mailing list will be taken by any of the OpenSBI maintainers and merged into the OpenSBI main repository using GitHub PRs.

All contributed work must follow the following rules:

  1. OpenSBI code should be written in accordance to the Linux coding style.
  2. This project embraces the Developer Certificate of Origin (DCO) for contributions. This means that you must agree to the following prior to submitting patches: if you agree with this developer certificate you acknowledge this by adding a Signed-off-by tag to your patch commit log. Every submitted patch must have this tag.
  3. A commit message must have a subject line, followed by a blank line, followed by a description of the patch content. A blank line and the author Signed-off-by tag must follow this description.
  4. A commit subject line must start with a prefix followed by a ":". Common prefixes are for example "lib:", "platform:", "firmware:", "docs:", "utils:" and "top:".
  5. Maintainers should use "Rebase and Merge" when using GitHub to merge pull requests to avoid creating unnecessary merge commits.
  6. Maintainers should avoid creating branches directly in the main riscv/opensbi repository. Instead prefer using a fork of the riscv/opensbi main repository and branches within that fork to create pull requests.
  7. A maintainer cannot merge his own pull requests in the riscv/opensbi main repository.
  8. A pull request must get at least one review from a maintainer.
  9. A pull request must spend at least 24 hours in review to allow for other developers to review.
