The first patch drops a now-dead guard\nin SwStatsCpu::finishFrame() flagged during review of the v2 series.\n\nChanges since v2:\n- AIQB parser: tightened the file header docstring to avoid duplicating\n the argparse description, cited ia_cmc_types.h as the format source,\n removed the --black-level CLI flag (black levels belong in\n CameraSensorHelper, not in the tuning emitted by this script),\n introduced a ColorMatrixRecord dataclass so the id=18 unpacking\n reads as named fields, switched the YAML output to PyYAML via a\n Dumper subclass, and now write the YAML to <sensor>.yaml so the\n diagnostic prints don't have to be filtered out. (Laurent Pinchart)\n- OV2740 tuning: no functional changes; regenerated against the\n updated parser to confirm the output is byte-identical.\n- SwStatsCpu sumShift_ guard: no functional changes; rebased so it\n applies cleanly on top of the merged v5 AGC/AWB series.\n\nLink to v2: https://patchwork.libcamera.org/project/libcamera/list/?series=5926\n\nSigned-off-by: Javier Tia <floss@jetm.me>\n---\nJavier Tia (3):\n libcamera: software_isp: Drop redundant sumShift_ guard in finishFrame\n ipa: simple: data: Add OV2740 tuning file\n utils: tuning: Add AIQB parser for Intel IPU6 sensors\n\n src/ipa/simple/data/meson.build | 1 +\n src/ipa/simple/data/ov2740.yaml | 72 +++++++\n src/libcamera/software_isp/swstats_cpu.cpp | 9 +-\n utils/tuning/parse_aiqb.py | 335 +++++++++++++++++++++++++++++\n 4 files changed, 412 insertions(+), 5 deletions(-)\n---\nbase-commit: 500c2320619a47bd01d1ffe69ca4cc6eae6e00e8\nchange-id: 20260511-ov2740-tuning-1c4e2204d27b\n\nBest regards,\n-- \nJavier Tia <floss@jetm.me>" }
