This is a follow-up of the discussions taken here: https://lore.kernel.org/linux-doc/20230704132812.02ba97ba@maurocar-mobl2/T/#t I sent a previous version as RFC. This is basically what we had there, with some improvements at test_list.py. It adds a new extension that allows documenting tests using the same tool we're using for DRM unit tests at IGT GPU tools: https://gitlab.freedesktop.org/drm/igt-gpu-tools. While kernel-doc has provided documentation for in-lined functions/struct comments, it was not meant to document tests. Tests need to be grouped by the test functions. It should also be possible to produce other outputs from the documentation, to integrate it with test suites. For instance, Internally at Intel, we use the comments to generate DOT files hierarchically grouped per feature categories. This is meant to be an initial series to start documenting kunit. It comes with a documenation for a kunit suite from drm at drm_buddy_test.c. My plan is that, once we get this merged, start documenting other unit tests and work to add extra requirements at the tool needed by Linux Kernel. On this series, we have: - patch 1: adds test_list.py - which is identical to the file with the same name I developed for IGT tree; - patch 2: adds test documentation from a single DRM kunit file (drm_buddy_test.c).
