GitHub Action
GKI Kernel Module Build Action
This GitHub Action is designed to automate the building of Android kernel modules out of the kernel source. It supports both aarch64 and x86_64 architectures, and can build kernels for different Android versions (GKI 2.0).
https://source.android.com/docs/core/architecture/kernel/gki-release-builds
The Android Kernel Build Action allows users to easily build kernels for Android devices by specifying a few parameters such as kernel source, branch, and configuration. The action automates the download of compilers, setting up necessary paths, and builds the kernel for the specified architecture.
