2024-06-17ipa: libipa: Add MatrixInterpolator classPaul Elder
Add a class to encapsulate the functionality of fetching a matrix based on an integer key, and interpolating if there is no exact match. This is expected to be used by both color correction matrices / crosstalk correction as well as lens shading correction. A cache is included only for exact matches of the key. The caller is expected to decide the tolererance for rounding.

2024-06-16libcamera: yaml_parser: Delegate YamlObject::get() to helper structureLaurent Pinchart
The YamlObject::get() function is a function template that gets fully specialized for various types. This works fine for non-template types, but specializing it for template types (e.g. a std::vector<U>) would require partial template specialization, which C++ allows for classes and variables but not functions. To work around this problem, delegate the implementation to a new YamlObject::Getter structure template, which will support partial specialization.

The YamlObject::get() function template is implemented for a set of basic types through template specializations. The function declaration uses std::enable_if_t<> guards to signal incorrect usage at compilation time. This however prevents the API to be extended with additional specializations in other compilation units. To prepare for new specializations of the function for the ipa::Vector and ipa::Pwl classes types, implemented in their respective compilation units, drop the std::enable_it_t<> guards. Incorrect usage will still be reported as link errors.

2024-06-13pipeline: rpi: Don't validate configuration in generateConfiguration()Naushir Patuck
generateConfiguration() called validate() as a final step, causing the stride and frameSize fields in StreamConfiguration to be filled in based on the pixel format and width/height. If a user application did not clear the stride field when setting up a custom pixel format and width/height, the pipeline handler would respect this stride and possibly overallocate buffers with a larger stride than needed. Fix this by removing the call to validate() completely, leaving the stride and frameSize fields defaulting to 0. Removal of this call is inconsequential as we hard-code a valid configuration for Raspberry Pi platforms in generateConfiguration().
