Larger values are possible, but this will need variable HBLANK control,\nwhich is not currently available.\n\nOne thing to note about this change: the imx477 does not report any indication\nof long exposure mode usage in metadata. Patch 1/4 addresses this by looking\nat the reported embedded data and comparing with DelayedControl values returned\nfor that frame, and deciding which one to \"believe\".\n\nNote that this series sits on top of my recent patch series for metadata\nparsing improvements:\nhttps://patchwork.libcamera.org/project/libcamera/list/?series=2128\n\nThanks,\nNaush\n\nNaushir Patuck (4):\n ipa: raspberrypi: Allow long exposure modes for imx477.\n pipeline: raspberrypi: Use priority write for vblank when writing\n sensor ctrls\n ipa: raspberrypi: Increase the default max frame duration to 250s\n ipa: raspberrypi: Make variable names consistent\n\n src/ipa/raspberrypi/cam_helper_imx477.cpp | 67 +++++++++++++++++++\n src/ipa/raspberrypi/raspberrypi.cpp | 10 +--\n .../pipeline/raspberrypi/raspberrypi.cpp | 37 +++++++---\n 3 files changed, 99 insertions(+), 15 deletions(-)"}
