2024-07-05libtuning: Only warn if processing returns NoneStefan Klug
There are valid cases where a module returns None. E.g. no images were provided for LSC calibration. We should however define proper semantics there. Continue with a warning for now.

2024-07-05libtuning: Migrate prints to python logging frameworkStefan Klug
In ctt_ccm.py the logging functionality of the Cam object was used. As we don't want to port over that class, it needs to be replaced anyways. While at it, also replace the eprint function as it doesn't add any value over the logging framework and misses the ability for easy log formatting. For nice output formatting add the coloredlogs library.

2024-05-08libcamera: Drop file name from header comment blocksLaurent Pinchart
Source files in libcamera start by a comment block header, which includes the file name and a one-line description of the file contents. While the latter is useful to get a quick overview of the file contents at a glance, the former is mostly a source of inconvenience. The name in the comments can easily get out of sync with the file name when files are renamed, and copy & paste during development have often lead to incorrect names being used to start with. Readers of the source code are expected to know which file they're looking it. Drop the file name from the header comment block. The change was generated with the following script: ---------------------------------------- dirs="include/libcamera src test utils" declare -rA patterns=( ['c']=' \* ' ['cpp']=' \* ' ['h']=' \* ' ['py']='# ' ['sh']='# ' ) for ext in ${!patterns[@]} ; do files=$(for dir in $dirs ; do find $dir -name "*.${ext}" ; done) pattern=${patterns[${ext}]} for file in $files ; do name=$(basename ${file}) sed -i "s/^\(${pattern}\)${name} - /\1/" "$file" done done ---------------------------------------- This misses several files that are out of sync with the comment block header. Those will be addressed separately and manually. Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Reviewed-by: Daniel Scally <dan.scally@ideasonboard.com>

Implement the extensible components of libtuning. This includes: - Parsers, for supporting different types of input config file formats - Generators, for supporting different types of output tuning file formats - Modules, for supporting different tuning modules for different algorithms and platforms No parsers, generators, or modules are actually implemented.
