True. I already told it at patch 0. I opted to not add a patch for it on this RFC series, to make it simpler. A simple logic at kernel-doc is enough to tell its state machine to ignore blocks that contain the KTEST_\w+: pattern: diff --git a/scripts/kernel-doc b/scripts/kernel-doc index d0116c6939dc..bf386460691f 100755 --- a/scripts/kernel-doc +++ b/scripts/kernel-doc @@ -259,6 +259,7 @@ my $doc_sect = $doc_com .

Just in case anyone was unable to receive the last email here is a copy of the message: Hi! This is such a cool patch series. I just have a few comments related to the output. In the html output the tests are listed as: ktest@drm_buddy_test@... I wonder if instead of using the file name of "drm_buddy_test" this could possibly be the suite name, "drm_buddy", as this is what users will call when using kunit.py to run the tests. Although "drm_buddy_test" is also the module name so I don't mind it too much. But in the future the file name and module name are not guaranteed to be the same for other tests. Most preferably, there would be a reference to the kunit suite name, file name, and the module name. This may be difficult to implement as these can all differ. I am currently working on the KUnit Attribute framework which saves the module name and I am thinking about also saving the file path as a future attribute. This could be a helpful framework for the KUnit tests specifically. I am not sure how easy it would be to access c objects/functions using this system. Finally, I was wondering if it is the intention to put a list of all KUnit tests that use this new feature into tests/kunit.rst or would this be broken up in some way.

I took some vacations and this series ended sleeping over other tasks on my todo list. Also, before sending another version, I wanted to have the test_list.py changes to make it generic enough to be merged on IGT, to avoid having a fork of it. Those got merged today. > In the html output the tests are listed as: > ktest@drm_buddy_test@… > > I wonder if instead of using the file name of “drm_buddy_test” this could > possibly be the suite name, “drm_buddy”, as this is what users will call > when using kunit.py to run the tests.

I guess it shouldn't be hard to do such change in a way that it won't affect its usage on IGT. We need to define what would be the best pattern. As this can be used for both kunit and selftests, I would place kunit at the beginning. Currently, we're using: kunit@<base file name without .c>@<test_name> Some possible patterns would be: kunit@<base file name without .c>@<suite name>@<test_name> kunit@<subsystem>@<base file name without .c>@<suite name>@<test_name> kunit@<subsystem>@<suite name>@<test_name> Would do you think it would work best? > This may be difficult to implement as these can all differ.

C language allows lots of flexibility with macros, making it hard to write a parser to read those C objects from the source. We have this at kernel-doc. As one of the people that did some work there, I can say that that several tricks are needed to keep this working. On the other hand, it should be easy to use the TestList class from test_list.py at kunit.py. So, kunit.py could use the data that came from the documentation directly. > Finally, I was wondering if it is the intention to put a list of all kunit > tests that use this new feature into tests/kunit.rst or would this be > broken up in some way IMO, it makes sense to break this per subsystem, and have an auto-generated index.rst pointing to the entire set of documents. We're already storing the subsystem at the documentation macros, so, IMO, it should shouldn't be hard to implement it. Regards, Mauro

How possible is it to separate out the file and suite name as headers? I think that this could reduce some of the repetition.
