From: Daniel Gomez <[email protected]> Add comprehensive kernel configuration fragment system that enables building kernels using merge_config.sh with focused configuration fragments instead of monolithic config files. Key features: - Modular Kconfig organization split into logical categories - Support for both x86_64 and ARM64 architectures - Architecture-specific fragment visibility (ARM64 page sizes) - Module dependency management for advanced features - New fragments for extended modversions, kmemleak, and module testing Fragment categories: - Essential: Core system requirements (64bit, systemd, distro, storage) - Security: Hardening and security features - Architecture: Platform-specific optimizations - Development: Debugging and diagnostic tools - Memory: NUMA and memory management features - Modules: Kernel module system configuration - Advanced: eBPF, XArray, and specialized features - Container: Virtualization and container support - Specialized: Minimal kernels, power management, Rust support - Legacy: Compatibility and legacy feature support Fragments origin: https://github.com/dkruces/linux-config-fragments Generated-by: Claude AI Signed-off-by: Daniel Gomez <[email protected]> --- This patch series introduces kernel configuration fragment support to kdevops, enabling modular kernel builds using merge_config.sh instead of monolithic configuration files. The fragment collection is based on linux-config-fragments [1], which provides a set of kernel configuration fragments for various use cases and architectures. While this implementation uses traditional Kconfig fragments as an immediate solution, I acknowledge the ongoing work towards SAT solver integration [2][3][4] as the proper long-term approach for deterministic dependency resolution in kernel configuration management. Testing shows successful kernel builds and boots with fragment-based configuration on ARM64 architecture. Fragments have been tested on x86_64 as well but not as part of the series.
