Instead of, or in addition to, the growing list of configuration environment variables, the whole configuration can be specified in a single configuration file. This is both simpler and more flexible. This is not a replacement for specific configuration files already present in libcamera. The patches implement what is needed to introduce a configuration file that can handle the current environment variables and software ISP TODOs. They demonstrate how to deal with the key points that must be considered. See commit messages for more details. The configuration file is a YAML file. It is looked up in user’s home directory or, if not present, in system-wide libcamera directories. Environment variables, if set, still take precedence. This patch series is not exhaustive, there can be future enhancements, most notably configuration file validation to avoid confusions caused by typos etc. Not everything has been tested because some of the patches are related to specific hardware. Changes in v3: - Added a configuration item for the newly introduced LIBCAMERA_PIPELINES_MATCH_LIST variable. - A minor indentation fix. - Fixed `pipelines.' x `pipeline.' configuration item naming mismatch. - Tuning files are looked up now by particular cameras attached rather than being specified for the whole pipeline. - Helpers use std::string& instead of char* for confPath arguments. - Protection against returning YamlObject::empty as a regular value (the problem has been probably exposed by addition of LIBCAMERA_PIPELINES_MATCH_LIST). Changes in v2: - Rebased on master. - Various cleanups, documentation improvements and minor fixes. - Configuration option for LIBCAMERA_RPI_TUNING_FILE added (Naush). - Two more patches for software ISP configuration added.
