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

If we are already separating documentation pages by subsystem, a
potential format could be:

File: 

 suite: 
List of Tests:


...

What do you think?

Thank you for your comments! Sorry for not answering earlier. 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.

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@@

Some possible patterns would be:

kunit@@@
kunit
kunit@@@

Would do you think it would work best?

I would prefer not. 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

I apologize that the last email included a HTML attachment of the message.

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.

Thanks!

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

Thanks!

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:

"/**" indicates a kernel-doc comment, and this is not a kernel-doc
comment.

$ scripts/kernel-doc -none drivers/gpu/drm/tests/drm_buddy_test.c 
drivers/gpu/drm/tests/drm_buddy_test.c:752: warning: cannot understand
function prototype: 'struct kunit_case drm_buddy_tests[] = '

Nowadays kernel-doc is part of W=1 builds.


BR,

[PATCH RFC 2/2] drm: add documentation for drm_buddy_test kUnit test

2023-07-12 Thread Mauro Carvalho Chehab
As an example for the new documentation tool, add a documentation
for drm_buddy_test.

I opted to place this on a completely different directory, in order
to make easier to test the feature with:

$ make SPHINXDIRS="tests" htmldocs

To avoid mailbombing on a large number of people, only mailing lists were C/C
