To get started with Android, you'll need to get familiar with Source Control Tools.
To initialize your local repository using the Google kernel manifest, use a command like this:
repo init -u https://android.googlesource.com/kernel/manifest.git -b common-android14-6.1-lts --depth=1
Then use a command like this to clone the local manifest at the root of your local repository:
git clone https://github.com/mt6897-devs/kernel_manifest .repo/local_manifests
Then to sync up:
repo sync
To build the GKI kernel image and the device kernel modules, use a command like this at the root of your local repository:
./kernel_device_modules-6.1/build.sh
Then every built artifacts are available at:
out/dist/
To update the prebuilt kernel repository, use the copy script in prebuilt kernel repository and find any missing files manually if needed.
