In the v2 patch, the AF starts to\nwork after AGC is stable. Moreover, AWB is properly suspended while AF\nis running to mitigate the performance impact.\n\nChanges in v2:\n1. A moving average based stability estimation strategy is used to\ndetermine the stability of AGC results.\n2. AF works after AGC is stable.\n3. AWB is suspended when AF is running. \n\nKate Hsuan (3):\n ipa: ipu3: agc: AGC exposure stability test\n ipa: ipu3: af: Trigger AF after AGC is stable\n ipa: ipu3: awb: Suspend AWB when AF is working\n\n src/ipa/ipu3/algorithms/af.cpp | 12 ++++++++++++\n src/ipa/ipu3/algorithms/af.h | 2 ++\n src/ipa/ipu3/algorithms/agc.cpp | 22 +++++++++++++++++++++-\n src/ipa/ipu3/algorithms/agc.h | 3 +++\n src/ipa/ipu3/algorithms/awb.cpp | 8 +++++++-\n src/ipa/ipu3/algorithms/awb.h | 1 +\n src/ipa/ipu3/ipa_context.h | 1 +\n 7 files changed, 47 insertions(+), 2 deletions(-)"}
