The module API version is used to determine the layout of struct IPAModuleInfo. Also update IPA module tests and Doxygen accordingly. Doxygen needs to be updated to accomodate __attribute__((packed)). Signed-off-by: Paul Elder Reviewed-by: Laurent Pinchart --- Changes in v3: - remove PIPELINE_VERSION documentation (since the macro was removed, since pipeline versions are now a single number) Changes in v2: - combine pipeline major and minor versions into one using the Documentation/Doxyfile.in | 7 +++--- include/libcamera/ipa/ipa_module_info.h | 10 ++++++-- src/libcamera/ipa_module.cpp | 32 ++++++++++++++++++++----- test/ipa/ipa_test.cpp | 27 +++++++++++---------- test/ipa/shared_test.cpp | 4 +++- 5 files changed, 55 insertions(+), 25 deletions(-) diff --git a/Documentation/Doxyfile.in b/Documentation/Doxyfile.in index 67eaded..ac70efb 100644 --- a/Documentation/Doxyfile.in +++ b/Documentation/Doxyfile.in @@ -2016,7 +2016,7 @@ ENABLE_PREPROCESSING = YES # The default value is: NO. # This tag requires that the tag ENABLE_PREPROCESSING is set to YES. -MACRO_EXPANSION = NO +MACRO_EXPANSION = YES # If the EXPAND_ONLY_PREDEF and MACRO_EXPANSION tags are both set to YES then # the macro expansion is limited to the macros specified with the PREDEFINED and @@ -2024,7 +2024,7 @@ MACRO_EXPANSION = NO # The default value is: NO. # This tag requires that the tag ENABLE_PREPROCESSING is set to YES. -EXPAND_ONLY_PREDEF = NO +EXPAND_ONLY_PREDEF = YES # If the SEARCH_INCLUDES tag is set to YES, the include files in the # INCLUDE_PATH will be searched if a #include is found. @@ -2057,7 +2057,8 @@ INCLUDE_FILE_PATTERNS = *.h # This tag requires that the tag ENABLE_PREPROCESSING is set to YES.
