Subject: [PATCH 00/10] drm: selftest: Convert to KUnit
KUnit unifies the test structure and provides helper tools that simplify
the development of tests. The basic use case allows running tests as regular
processes, which makes it easier to run unit tests on a development machine
and to integrate the tests into a CI system.
That said, the conversion of selftests for DRM to KUnit tests is beneficial
as it unifies the testing API by using the KUnit API.
KUnit is beneficial for developers as it eases the process to run unit tests.
It is possible to run the tests by using the kunit-tool on userspace with the
following command:
./tools/testing/kunit/kunit.py run --kunitconfig=drivers/gpu/drm/tests --arch=x86_64
For CI system, it is possible to execute during the build. But, we also think
about IGT: we are developing a patch to introduce KUnit to IGT.
These patches were developed during a KUnit hackathon [0] last October. Now,
we believe that both the IGT side and the Kernel side are in good shape for
submission.
If you are willing to check the output, here is the Pastebin with the output
and execution times [1].
