feat(testing): add kernel coverage integration — Phase 3 complete
tools/uos-boot-test/uos-kernel-coverage.py:
- New coverage orchestration script (376 lines)
- Integrates with existing uos-cover tools
- Workflow: instrument → build → run → extract → parse → report
- Supports --arch, --report, --timeout, --skip-build flags
- Handles missing UMAP data gracefully (expected for initial integration)
kernel/Makefile:
- Add coverage targets: coverage, coverage-armv7, coverage-aarch64, etc.
- Configurable COVERAGE_TOOL and COVERAGE_REPORT paths
.github/workflows/ci.yml:
- Add 'kernel-coverage' job for armv7
- Runs after kernel-build
- Installs QEMU + cross-compiler + Python
- Runs uos-kernel-coverage.py
- Uploads coverage report as artifact
Phase 3 of testing roadmap: Coverage analysis infrastructure operational.
Note: Full coverage requires libuoscov runtime in kernel (future work).
