ci-kernels

A collection of kernels used for CI builds.

1. Update kernel versions in versions.json
2. Commit and make a PR.

You can approximate CI by running buildx.sh:

$ ./buildx.sh 6.1 amd64 vmlinux --tag foo:vmlinux

To inspect the result of a build:

$ ./buildx.sh 6.1 amd64 build-vmlinux-debug
...

$ docker run -it sha256:18d00182c5495376d87dfef5a4363a1b2cbd936af4f893ab437ce006b0f893d4

Updating versions

Use update-version.sh (requires jq):

./update-versions.sh

Updating the configuration

The configuration consists of common options in config and platform specific options in config-arm64 and config-x64_64.

To add a new config option:

1. Try adding it to config (keep sorted alphabetically)
2. In a checkout of the Linux source code:

   TARGETPLATFORM=linux/arm64 /path/to/configure-vmlinux.sh

3. If any symbols are missing you can now run make menuconfig and search for the missing symbols. Figure out which dependencies are missing and add them to the config as well.

Add the config to the arch specific files if it isn't available in general.

Updating the builder

The builder image is still built manually.

1. make image
2. make push
3. Add files, commit and make a PR.
