+KUnit (Kernel unit testing framework) provides a common framework for unit tests +within the Linux kernel.
I think that it will be useful to have a reference to the KUnit kernel doc here, something like the following:
`KUnit https://docs.kernel.org/dev-tools/kunit/index.html`_ (Kernel Unit...
There is a link in the next paragraph. Once the documentation is generated the path "Documentation/dev-tools/kunit/start.rst" is transformed into a link.

+How to run the tests? +~~~~~~~~~~~~~~~~~~~~~
+In order to facilitate running the test suite, a configuration file is present +in ``drivers/gpu/drm/kunit/.kunitconfig``. It can be used by ``kunit.py`` as +follows:
+.. code-block:: bash
- $ ./tools/testing/kunit/kunit.py run --kunitconfig=drivers/gpu/drm/kunit \
--kconfig_add CONFIG_VIRTIO_UML=y \
--kconfig_add CONFIG_UML_PCI_OVER_VIRTIO=y
+.. note::
- The configuration included in ``.kunitconfig`` should be as generic as
- possible.
- ``CONFIG_VIRTIO_UML`` and ``CONFIG_UML_PCI_OVER_VIRTIO`` are not
- included in it because they are only required for User Mode Linux.
Maybe also add something like this ?
For example, the following command can be used to run the test for x86_64:
$ ./tools/testing/kunit/kunit.py run --kunitconfig=drivers/gpu/drm/kunit \ --arch=x86_64
I didn't want to go into much detail because the KUnit docs are a very good resource and already explain how to run the tests in your favorite architecture.
Since running the test on x86_64 should not change the results, I'd prefer to keep it simple and trust the KUnit docs for the "advanced" options.
Regardless, the patch looks good to me:

Thanks a lot for taking the time to review it. I'll add the tag if a v4 is required after chatting with the guys working on the AMDGPU tests.
