The problem is due to that the codes from Chrome\nOS not handling memories correctly. In result, the statistic as input to AIQ\nis cleared early and the calculated exposure is wrong. A similiar issue\nprevent it to apply lens shading correction too, which causes crash due to\ninvalid contents of SA results.\n\nThe patch series fixes the issue by:\n1. Refactor the memory recycles and fix copying overflown.\n2. Apply shading lens correction to further brighten the image.\n\nhanlinchen (3):\n ipu3: Remove the usage of SharedItemPool\n ipu3: Change Macro migrated from Chrome OS to its std version\n accordingly\n ipu3: Apply shading adapter as part of AIQ::run2a()\n\n aiq/aiq.cpp | 20 ++++-\n aiq/aiq.h | 4 +-\n aiq/aiq_input_parameters.cpp | 50 +++++-------\n aiq/aiq_results.cpp | 91 +++++++++-------------\n ipu3.cpp | 2 +-\n stats/ipa_ipu3_stats.cpp | 145 ++++++-----------------------------\n stats/ipa_ipu3_stats.h | 41 ++++++----\n stats/meson.build | 1 -\n stats/shared_item_pool.cpp | 129 -------------------------------\n stats/shared_item_pool.h | 114 ---------------------------\n 10 files changed, 127 insertions(+), 470 deletions(-)\n delete mode 100644 stats/shared_item_pool.cpp\n delete mode 100644 stats/shared_item_pool.h" }
