That way you won't have to prefix everything\n> with data->, and you'll avoid passing sensorConfig to loadIPA().\n\nAs explained in the original reply, I put this block here instead of loadIPA()\nas the DelayedControls helper needs the device node already opened in order to\nvalidate the controls that are passed in via params. If I were to move this\nto loadIPA(), it would split the opening of unicam_[Unicam::Image] and\nunicam_[Unicam::Embedded] into two separate locations, which I thought\nmight be undesirable.\n\nRegards,\nNaush\n\nNaushir Patuck (7):\n ipa: Add sensor model string to IPASettings\n pipeline: ipa: raspberrypi: Open the CamHelper on ipa::init()\n pipeline: raspberrypi: Conditionally open the embedded data node\n ipa: raspberrypi: Move the controller initialise to ipa::init()\n ipa: raspberrypi: Remove unused member variable\n ipa: raspberrypi: Rationalise parameters to ipa::start()\n ipa: raspberrypi: Rationalise parameters to ipa::configure()\n\n include/libcamera/ipa/core.mojom | 8 ++\n include/libcamera/ipa/raspberrypi.mojom | 27 ++--\n src/ipa/raspberrypi/raspberrypi.cpp | 110 +++++++---------\n src/libcamera/pipeline/ipu3/ipu3.cpp | 3 +-\n .../pipeline/raspberrypi/raspberrypi.cpp | 124 +++++++-----------\n src/libcamera/pipeline/vimc/vimc.cpp | 2 +-\n test/ipa/ipa_interface_test.cpp | 2 +-\n 7 files changed, 116 insertions(+), 160 deletions(-)" }
