Log the current working directory in `build-in-docker.sh` to improve the
debugging process during kernel module compilation. This update helps
track the build context path passed to the Docker container.
Enable parallel builds for kernel modules targeting multiple kernel
headers. This optimization reduces build times and improves CI
efficiency. Adjusted workflow steps to ensure compatibility with all
supported environments.
Introduce a workflow to build kernel modules for multiple header packages on PRs and releases. PR builds verify compilation, while release builds package outputs and publish them to a Gitea release. This enhances automation and ensures compatibility across target environments.
The `.gitea/workflows/ci.yml` file was removed as it is no longer needed. The build steps defined in the file have been deprecated and are not in use in the current CI/CD pipeline.
Introduce a basic CI pipeline configuration using GitHub Actions. The
workflow runs on Ubuntu and consists of three simple build steps, which
print progress messages. This setup will serve as a foundation for
future CI/CD enhancements.
Expand the documentation to include details on GPIO descriptor
lookup using chip label and hardware offset, replacing the deprecated
global GPIO number approach. Added instructions for verifying the module's
version magic to ensure compatibility with the running kernel. These
updates aim to prevent common initialization and deployment errors.
Replace legacy gpio_to_desc() with GPIO descriptor resolution by chip label
and hardware number, ensuring compatibility with kernels using non-zero
gpiochip bases. Added `selftest.sh` for non-persistent module testing, which
performs a hardware self-test and verifies wiring before connecting the real
bus. Included a detailed README.md documenting the self-test process.
