The latest version\nof the kernel support is available at:\n\n[1] https://patchwork.linuxtv.org/project/linux-media/list/?series=26362\n\nThis version re-uses the pipeline as submitted by Niklas, adapted to use\nthe new RPP-X1 meta formats introduced in [1].\n\nThe series still depends on Hans'\n[2] https://patchwork.libcamera.org/project/libcamera/list/?series=5940\nwhich I included in the series to maintain it buildable.\n\nAs the pipeline and the IPA have different names.\n\nOn the IPA side instead, this series introduces a new IPA dedicated to\nRPP-X1 without any dependency on the RkISP1 support. It includes only\n2 algorithms for the time being, based on the recent reworks of libipa:\n[3] https://patchwork.libcamera.org/project/libcamera/list/?series=5992\n\nI took the two patches that introduce AwbAlgorithm and CcmAlgorithm in\nthe series as well, to maintain the series buildable.\n\nThis series constitute then the first step for being able to add more\nalgorithms to the RPP-X1 IPA.\n\nHowever, we need to resolve the issue addressed by [2] first, otherwise\nwe won't be able to use the 'rpp-x1' IPA for the 'rcar-gen4' pipeline.\n\nSigned-off-by: Jacopo Mondi <jacopo.mondi@ideasonboard.com>\n---\nHans de Goede (1):\n libcamera: ipa_manager: Create IPA by name\n\nJacopo Mondi (12):\n ipa: ipa_module: Remove pipelineName\n ipa: Allow pipelines to have differently named IPA\n ipa: libipa: awb: Reimplement AwbAlgorithm\n ipa: libipa: Add CcmAlgorithm to libipa\n include: linux: Add uAPI file for Dreamchip RPP-X1\n include: v4l2-isp: Add support for statistics\n include: videodev2: Add RPP-X1 meta formats\n ipa: libipa: Introduce V4L2Stats\n ipa: rppx1: Add RppX1Params and RppX1Stats\n ipa: rppx1: Add RPP-X1 IPA skeleton\n ipa: rppx1: Add AWB algorithm\n ipa: rppx1: Add Ccm algorithm\n\nNiklas Söderlund (1):\n libcamera: pipeline: Add R-Car Gen4 ISP pipeline\n\n Documentation/Doxyfile-common.in | 1 +\n include/libcamera/internal/ipa_manager.h | 8 +-\n include/libcamera/internal/ipa_module.h | 4 +-\n include/libcamera/internal/pipeline_handler.h | 9 +-\n include/libcamera/ipa/ipa_module_info.h | 1 -\n include/libcamera/ipa/meson.build | 1 +\n include/libcamera/ipa/rppx1.mojom | 41 ++\n include/linux/media/dreamchip/rppx1-config.h | 710 ++++++++++++++++++++++\n include/linux/media/v4l2-isp.h | 125 ++--\n include/linux/videodev2.h | 4 +\n meson.build | 1 +\n meson_options.txt | 5 +-\n src/ipa/ipu3/ipu3.cpp | 1 -\n src/ipa/libipa/awb.cpp | 527 ++++++++++++++--\n src/ipa/libipa/awb.h | 114 +++-\n src/ipa/libipa/awb_bayes.cpp | 42 +-\n src/ipa/libipa/awb_bayes.h | 11 +-\n src/ipa/libipa/awb_grey.cpp | 25 +-\n src/ipa/libipa/awb_grey.h | 5 +-\n src/ipa/libipa/ccm.cpp | 265 ++++++++\n src/ipa/libipa/ccm.h | 84 +++\n src/ipa/libipa/meson.build | 4 +\n src/ipa/libipa/v4l2_stats.cpp | 241 ++++++++\n src/ipa/libipa/v4l2_stats.h | 67 ++\n src/ipa/mali-c55/mali-c55.cpp | 1 -\n src/ipa/meson.build | 41 +-\n src/ipa/rkisp1/algorithms/awb.cpp | 223 +------\n src/ipa/rkisp1/algorithms/awb.h | 18 +-\n src/ipa/rkisp1/ipa_context.h | 29 +-\n src/ipa/rkisp1/rkisp1.cpp | 1 -\n src/ipa/rpi/pisp/pisp.cpp | 1 -\n src/ipa/rpi/vc4/vc4.cpp | 1 -\n src/ipa/rppx1/algorithms/awb.cpp | 297 +++++++++\n src/ipa/rppx1/algorithms/awb.h | 48 ++\n src/ipa/rppx1/algorithms/ccm.cpp | 124 ++++\n src/ipa/rppx1/algorithms/ccm.h | 54 ++\n src/ipa/rppx1/algorithms/meson.build | 6 +\n src/ipa/rppx1/ipa_context.cpp | 103 ++++\n src/ipa/rppx1/ipa_context.h | 68 +++\n src/ipa/rppx1/meson.build | 30 +\n src/ipa/rppx1/module.h | 27 +\n src/ipa/rppx1/params.h | 108 ++++\n src/ipa/rppx1/rppx1.cpp | 280 +++++++++\n src/ipa/rppx1/stats.h | 62 ++\n src/ipa/simple/soft_simple.cpp | 1 -\n src/ipa/vimc/vimc.cpp | 1 -\n src/libcamera/ipa_manager.cpp | 34 +-\n src/libcamera/ipa_module.cpp | 27 +-\n src/libcamera/pipeline/rcar-gen4/frames.cpp | 281 +++++++++\n src/libcamera/pipeline/rcar-gen4/frames.h | 86 +++\n src/libcamera/pipeline/rcar-gen4/isp.cpp | 228 +++++++\n src/libcamera/pipeline/rcar-gen4/isp.h | 45 ++\n src/libcamera/pipeline/rcar-gen4/meson.build | 8 +\n src/libcamera/pipeline/rcar-gen4/rcar-gen4.cpp | 810 +++++++++++++++++++++++++\n src/libcamera/pipeline/rcar-gen4/vin.cpp | 391 ++++++++++++\n src/libcamera/pipeline/rcar-gen4/vin.h | 67 ++\n test/ipa/ipa_module_test.cpp | 3 -\n 57 files changed, 5349 insertions(+), 451 deletions(-)\n---\nbase-commit: cde4eddf895cd09d05137bd99425d238cd8a6018\nchange-id: 20260618-rppx1-ipa-189ef7c5b18b\n\nBest regards," }
