It connects\neverything together such that a platform's tuning script can very easily\ncustomize tuning modules in a variety of ways, even including the format\nof the input configuration file and the output tuning file. These are\nall implemented in patches 1/12 to 3/12 (split from one to three patches\nas of v3).\n\nThe input configuration file and output tuning file could have different\nformats as well, hence why these have their own classes. As of v1, only\nthe raspberrypi's formats were implemented, in patches 7/12 and 8/12\nrespectively. As of v2, output for yaml was added in patch 10/12. A\nskeleton for yaml input is added as well in patch 9/12, though it is not\nimplemented yet as there is no specification for the yaml input\nconfiguration format, and the only existing user of it doesn't actually\nneed a configuration file.\n\nAs of v2, it became apparent that it was infeasible to create an ALSC\nmodule (that's what we're starting with) that could completely support\ndifferent platforms with configuration options alone. So, the ALSC\nmodule was split into a base one (patch 4/12), with variations for\nraspberrypi and rkisp1 implemented on top of it in patches 5/12 and 6/12\nrespectively. I think they came out quite nice, and they are still more\nmanageable than an entirely new tuning module per platform.\n\nv2:\nI have also since managed to get test images and so this entire thing\nruns! Even though the rkisp1 tuning script (patch 12/12) says \"WIP\", it\ndoes run and outputs a valid tuning file. I haven't tried using the\ntuning file with libcamera though, as it is missng the /other/ algorithm\ntuning results.\n\nThe output from the libtuning-based alsc-only raspberrypi tuning script\n(patch 11/12) has been confirmed to be character-for-character exactly\nthe same as the output from ctt's alsc-only tuning script.\n\n(P.S. I'll be uncontactable by IRC for a while because of DNS.)\n\nPaul Elder (12):\n utils: tuning: libtuning: Implement the core of libtuning\n utils: tuning: libtuning: Implement math helpers\n utils: tuning: libtuning: Implement extensible components of libtuning\n utils: libtuning: modules: Add base LSC module\n utils: libtuning: modules: alsc: Add raspberrypi ALSC module\n utils: libtuning: modules: alsc: Add rkisp1 LSC module\n utils: libtuning: parsers: Add raspberrypi parser\n utils: libtuning: generators: Add raspberrypi output\n utils: libtuning: parsers: Add yaml parser\n utils: libtuning: generators: Add yaml output\n utils: tuning: Add alsc-only libtuning raspberrypi tuning script\n utils: tuning: Add tuning script for rkisp1\n\n utils/tuning/README.rst | 11 +\n utils/tuning/libtuning/__init__.py | 13 +\n utils/tuning/libtuning/average.py | 21 +\n utils/tuning/libtuning/generators/__init__.py | 6 +\n .../tuning/libtuning/generators/generator.py | 15 +\n .../generators/raspberrypi_output.py | 114 ++++\n .../libtuning/generators/yaml_output.py | 123 +++++\n utils/tuning/libtuning/gradient.py | 75 +++\n utils/tuning/libtuning/image.py | 133 +++++\n utils/tuning/libtuning/libtuning.py | 203 +++++++\n utils/tuning/libtuning/macbeth.py | 516 ++++++++++++++++++\n utils/tuning/libtuning/macbeth_ref.pgm | 6 +\n utils/tuning/libtuning/modules/__init__.py | 0\n .../tuning/libtuning/modules/lsc/__init__.py | 7 +\n utils/tuning/libtuning/modules/lsc/lsc.py | 72 +++\n .../libtuning/modules/lsc/raspberrypi.py | 250 +++++++++\n utils/tuning/libtuning/modules/lsc/rkisp1.py | 114 ++++\n utils/tuning/libtuning/modules/module.py | 33 ++\n utils/tuning/libtuning/parsers/__init__.py | 6 +\n utils/tuning/libtuning/parsers/parser.py | 21 +\n .../libtuning/parsers/raspberrypi_parser.py | 93 ++++\n utils/tuning/libtuning/parsers/yaml_parser.py | 17 +\n utils/tuning/libtuning/smoothing.py | 24 +\n utils/tuning/libtuning/utils.py | 152 ++++++\n utils/tuning/raspberrypi/__init__.py | 0\n utils/tuning/raspberrypi/alsc.py | 19 +\n utils/tuning/raspberrypi_alsc_only.py | 23 +\n utils/tuning/rkisp1.py | 43 ++\n 28 files changed, 2110 insertions(+)\n create mode 100644 utils/tuning/README.rst\n create mode 100644 utils/tuning/libtuning/__init__.py\n create mode 100644 utils/tuning/libtuning/average.py\n create mode 100644 utils/tuning/libtuning/generators/__init__.py\n create mode 100644 utils/tuning/libtuning/generators/generator.py\n create mode 100644 utils/tuning/libtuning/generators/raspberrypi_output.py\n create mode 100644 utils/tuning/libtuning/generators/yaml_output.py\n create mode 100644 utils/tuning/libtuning/gradient.py\n create mode 100644 utils/tuning/libtuning/image.py\n create mode 100644 utils/tuning/libtuning/libtuning.py\n create mode 100644 utils/tuning/libtuning/macbeth.py\n create mode 100644 utils/tuning/libtuning/macbeth_ref.pgm\n create mode 100644 utils/tuning/libtuning/modules/__init__.py\n create mode 100644 utils/tuning/libtuning/modules/lsc/__init__.py\n create mode 100644 utils/tuning/libtuning/modules/lsc/lsc.py\n create mode 100644 utils/tuning/libtuning/modules/lsc/raspberrypi.py\n create mode 100644 utils/tuning/libtuning/modules/lsc/rkisp1.py\n create mode 100644 utils/tuning/libtuning/modules/module.py\n create mode 100644 utils/tuning/libtuning/parsers/__init__.py\n create mode 100644 utils/tuning/libtuning/parsers/parser.py\n create mode 100644 utils/tuning/libtuning/parsers/raspberrypi_parser.py\n create mode 100644 utils/tuning/libtuning/parsers/yaml_parser.py\n create mode 100644 utils/tuning/libtuning/smoothing.py\n create mode 100644 utils/tuning/libtuning/utils.py\n create mode 100644 utils/tuning/raspberrypi/__init__.py\n create mode 100644 utils/tuning/raspberrypi/alsc.py\n create mode 100755 utils/tuning/raspberrypi_alsc_only.py\n create mode 100755 utils/tuning/rkisp1.py" }
