I believe this to be a false\npositive, but it still points to an issue in the code. Patch 1/2 fixes\nthe issue, which also gets rid of the warning. However, this modifies\nthe IPU3 BDS height calculation, which can result in unwanted side\neffects (the code is quite fragile and very far from correct).\n\nPatch 2/2 takes a different approach and just silences the warning,\nleaving the incorrect BDS height calculation to be addressed later.\n\nOnly one of the two patches should be merged now. In addition to\nreviewing the them, I'll thus ask you to vote for your favourite\ncandidate :-)\n\nLaurent Pinchart (2):\n libcamera: pipeline: ipu3: Fix incorrect bdsHeight calculation\n libcamera: pipeline: ipu3: Fix warning when compiled with optimization\n\n src/libcamera/pipeline/ipu3/imgu.cpp | 14 ++++++++------\n 1 file changed, 8 insertions(+), 6 deletions(-)" }
