Kernel Patches Daemon

Kernel Patches Daemon (kpd), watches patchwork for new series sent to the mailing list, applies the series on top of repo.

repo maintains base branches by pulling updates from <upstream>@<upstream_branch> and applying the CI files from <ci_repo>@<ci_branch> to it.

When kpd sees a new or updated series, it applies the patches from the series on top of one of the maintained branch and creates a PR against it.

This in turns triggers the Github workflows copied from ci_repo.

When the workflow runs are reporting back, kpd updates the relevant checks for this series on patchwork (when the configuration provides a pw_token and pw_user).

Configuration

kpd.conf.template is an example config based on the setup of https://github.com/kernel-patches/bpf

The branch bpf-next uses Github personal token to authenticate, while the branch bpf uses Github App.

When using a GH app, it needs to have the following read and write access:

• Content (write to repo)
• Pull request (create PRs)
• Workflow
