===== CIP kernel release tutorial ====

This is a kernel release tutorial for [[https://git.kernel.org/pub/scm/linux/kernel/git/cip/linux-cip.git|CIP linux kernel]].

==== 1. Check out -cip remote branch to local branch. ====


For example, if you want to check out cip/linux-4.19.y-cip remote branch as linux-4.19.y-cip local branch, do following:
  
  git checkout -b linux-4.19.y-cip cip/linux-4.19.y-cip

==== 2. Update the localversion-cip file and commit it. ====

The content of this file is -cipN. N means the number of releases.

==== 3. Create a release tag. ====

The tag is the kernel version to be released plus the CIP 
release version.For example, when releasing cip32 based on v4.4.176, the tag is 
v4.4.176-cip32. When creating tags, sign with GnuPG.

==== 4. Push updates into the CIP's kernel repository. ====

The branch to push is as follows:

  * 4.4.y kernel:  linux-4.4.y-cip
  * 4.19.y kernel: linux-4.19.y-cip

And the tag needs to be pushed.
If you want to push only a specific tag, do the following:

  git push cip v4.4.176-cip32

or

  git push cip refs/tags/v4.4.176-cip32

==== 5. Check out the -rebase remote branch. ====

NOTE: The -rebase branch is a branch to make it easy to understand changes between LTS and CIP.

==== 6. Rebase commits on target kernel version. ====

After rebasing,

  * Cherry-pick CIP-specific commits that have been added to the non-rebased branch
  * Check that the result is now identical to the non-rebased branch

Once the stable branch reaches end-of-life the CIP branch won't need to be rebased any more but those extra steps will still be needed.

==== 7. Create a tag for rebase release. ====

This is also signed by GPG.

==== 8. Push updates of -rebase branch into the CIP's kernel repository. ====

The branch to push is as follows:

  * 4.4.y kernel:  linux-4.4.y-cip-rebase
  * 4.19.y kernel: linux-4.19.y-cip-rebase

And the tag needs to be pushed.

==== 9. Send release announcement to cip-dev@lists.cip-project.org. ====
