Thanks a lot for the quick feedback. I just cc'ed kunit-dev@xxxxxxxxxxxxxxxx. For anyone joining the conversation, here is the link to the patch and the cover letter with some questions: https://lore.kernel.org/dri-devel/20220530102017.471865-1-jose.exposito89@xxxxxxxxx/T/ > > > --- > > drivers/gpu/drm/Kconfig | 12 ++ > > drivers/gpu/drm/Makefile | 3 + > > drivers/gpu/drm/drm_format_helper_test.c | 166 +++++++++++++++++++++++ > > 3 files changed, 181 insertions(+) > > create mode 100644 drivers/gpu/drm/drm_format_helper_test.c > > > > diff --git a/drivers/gpu/drm/Kconfig b/drivers/gpu/drm/Kconfig > > index e88c497fa010..d92be6faef15 100644 > > --- a/drivers/gpu/drm/Kconfig > > +++ b/drivers/gpu/drm/Kconfig > > @@ -76,6 +76,18 @@ config DRM_KMS_HELPER > > help > > CRTC helpers for KMS drivers. > > > > +config DRM_FORMAR_HELPER_TEST > > + bool "drm_format_helper tests" if !KUNIT_ALL_TESTS > > + depends on DRM && KUNIT=y > > + select DRM_KMS_HELPER > > + default KUNIT_ALL_TESTS > > + help > > + KUnit tests for the drm_format_helper APIs.

My understanding from the docs: https://docs.kernel.org/dev-tools/kunit/run_wrapper.html#create-a-kunitconfig-file Is that, like the .config file, the .kunitconfig file is not meant to be included in git, but I'm sure someone else will clarify this point.
