+Unit testing
+============
+
+KUnit
+-----
+
+KUnit (Kernel unit testing framework) provides a common framework for unit tests
+within the Linux kernel.
+
+This section covers the specifics for the DRM subsystem. For general information
+about KUnit, please refer to Documentation/dev-tools/kunit/start.rst.
+
+How to run the tests?
+~~~~~~~~~~~~~~~~~~~~~
+
+In order to facilitate running the test suite, a configuration file is present
+in ``drivers/gpu/drm/tests/.kunitconfig``. It can be used by ``kunit.py`` as
+follows:
+
+.. code-block:: bash
+
+	$ ./tools/testing/kunit/kunit.py run --kunitconfig=drivers/gpu/drm/tests \
+		--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.
+
+
