It is modelled as a V4L2M2MConverter and has a\nhelper to support scaler crop control. Extensions to the base converter\ninterface has also been done initially in the series.\n\nPatch 1/4 add ability to add features to the Converter interface.\nEach Converter can dictate its own features it can support\n\nPatch 2/4 adds crop feature enumeration and virtual functions and\ngets implemented in the V4L2 M2M converter. \n\nPatch 3/4 prepares the rkisp1 pipeline handler to register controls\nfor the camera, outside of the IPA. The dw100 converter will let us\nsupport scaler crop - which will be registered as one of the camera\ncontrols.\n\nPatch 4/4 plumbs the DW100 as converter in the rkisp1 pipeline handler\n\nSeries is based on top of \n[PATCH] libcamera: v4l2_videodevice: Add getSelection() function\n\nTesting:\n--------\nThe series is tested on i.MX8MP and cam utility, by setting scaler crop\ncontrol via capture script with IMX283 attached to isp0.\n\nChanges in v8:\n- Fix subject to \"rkisp1: Plumb the DW100 dewarper as converter\"\n- Fix documentation in 2/4\n- Drop features_ member variable in 2/4 in V4L2M2MStream class\n- Use V4L2_SEL_TGT_CROP_BOUNDS for querying max crop bound (2/4)\n- Introduce V4L2M2MStream::getSelection() helper as well (2/4)\n- Fix race while setting scalercrop metadata in 4/4\n- Format debug logs in 2/4 and 4/4\n- Reduce indentation in 2/4 for discovering input crop\n\nChanges in v7:\n- Documentation improvements for input crop (1/4)\n- Crop feature now discovered dynamically at construction (2/4)\n- Handling of scaler crop control is deferred. Now scaler\n crop is applied at dewarper after buffer from ISP is ready (4/4)\n- Add explanatory comments about dw100/i.MX8MP platform (4/4)\n- Drop dw100 Converter sub-classing from v6\n- lower indentation (4/4)\n- report scaler crop value for all frames now. (4/4)\n- Use ScopeExitActions on dewarp cleanup paths (4/4)\n- copy updateControls() documentation from IPU3 (3/4)\n\nChanges in v6:\n- clarify crop expectations - set on input side\n- Rename setCrop() to setInputCrop\n- Rename getFeatures() to features()\n- Rename getCropBounds() to inputCropBounds()\n- rename Features::Crop to Features::InputCrop\n- Document crop functionality properly\n- Improve error paths\n- exportsBuffers() between RkISP1Path<>dewarper instead of\n allocateBuffers.\n\nChanges in v5:\n- Return -ENOTSUP for base implementation for virtual setCrop() in 2/5\n- Return configured size for base implemention for virtual getCropBounds\n in 2/5.\n- Fix a bug in getting crop bounds when streams are not configured\n- drop getSelection() V4L2VideoDevices additions from v4. we can get\n bounds by setSelection by setting 1x1 and UINT_MAX x UINT_MAX\n rectangles.\n\nchanges in v4:\n- rework Converter Interface to expose Features\n- Add Crop Feature interface in Converter setCrop and setCropBound\n- Implement cropping in V4L2M2MConverter for V4L2 M2M based converters\n- Introduce useDewarper_ to denote when to use dewarper (simplied code\n reading).\n- Trivial typo fixing.\n\nChanges in v3:\n- Base on top of [2]\n- Model dewarper class as converter, so can be used with Simple\n pipeline-handler/ISI\n\nChanges in v2:\n- Fix raw capture configuration, disable dewarper in that case\n\nUmang Jain (4):\n libcamera: converter: Add interface for feature flags\n libcamera: converter: Add interface to support cropping capability\n libcamera: rkisp1: Prepare for additional camera controls\n libcamera: rkisp1: Plumb the dw100 dewarper as V4L2M2M converter\n\n include/libcamera/internal/converter.h | 19 +-\n .../internal/converter/converter_v4l2_m2m.h | 11 +\n src/libcamera/converter.cpp | 64 ++++-\n .../converter/converter_v4l2_m2m.cpp | 114 +++++++++\n src/libcamera/pipeline/rkisp1/rkisp1.cpp | 228 +++++++++++++++++-\n 5 files changed, 424 insertions(+), 12 deletions(-)" }
