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.
