Dominium-Apum/kernel_xiaomi_chime ? reverse-engineered prompt

I want to build and maintain a custom Linux 4.19 kernel for the POCO M3 and Redmi 9T, plus their close variants.

Please make the project easy to build from GitHub Actions, and keep it friendly for Android users who just want a flashable kernel zip at the end. I also want a separate Android friendly branch that can be used alongside AOSP, and it should include KernelSU support there if that fits this codebase. Keep the main branch as the more experimental rolling branch, and make sure the build instructions are clear enough that someone can fork the repo, run the workflow, and get the artifact without guessing.

If anything in the kernel tree needs a quick cleanup or a build fix for these devices, do that too. Look up current docs online if you need to, and keep the changes focused on making this kernel easier to build, test, and use on these phones.
