The changes include restructuring the DPF configuration handling, improving readability, and adding support for sensor-specific DPF parameters. Support mode selection base on tuning parameters Key changes: - Inlined parseModes into parseConfig for cleaner initialization. - Refactored mode lookup to use a dictionary, facilitating name-based lookup in tuning files. - Introduced ActiveMode as an optional tuning parameter to set the default DPF state. - Improved code structure in prepare() by using helper functions for enabled and disabled states. - Enhanced debug logging for ISP parameter verification. - Provided initial tuning data for IMX219, OV5640, and OV5647. Changes since v10: - Replace kModeMap with control:draft::NoiseReductionModeNameValueMap - Update Tuning DPF's dictionary key as NoiseReductionModeNameValueMap k/v Rui Wang (7): ipa: rkisp1: algorithms: dpf: refactor DPF parsing and initialization ipa: rkisp1: algorithms: dpf: Implement mode switching ipa: rkisp1: algorithms: register noise reduction controls ipa: rkisp1: algorithms: dpf: Refactor prepare() into helpers ipa: rkisp1: algorithms: dpf: Add detailed config logging ipa: rkisp1: algorithms: data: enable DPF tuning for sensors ipa: rkisp1: algorithms: data: Add OV5647/IMX219 tuning file src/ipa/rkisp1/algorithms/dpf.cpp | 277 ++++++++++++++++++++++++------ src/ipa/rkisp1/algorithms/dpf.h | 25 ++- src/ipa/rkisp1/data/imx219.yaml | 25 +++ src/ipa/rkisp1/data/meson.build | 1 + src/ipa/rkisp1/data/ov5640.yaml | 64 +++++-- src/ipa/rkisp1/data/ov5647.yaml | 34 ++++ src/ipa/rkisp1/rkisp1.cpp | 1 - 7 files changed, 361 insertions(+), 66 deletions(-) create mode 100644 src/ipa/rkisp1/data/ov5647.yaml
