57 KUnit Tests
58 ===========
59
60 The VC4 Driver uses KUnit to perform driver-sp
61 integration tests.
62
63 These tests are using a mock driver and can be
64 command below, on either arm or arm64 architec
65
66 .. code-block:: bash
67
68 $ ./tools/testing/kunit/kunit.py run \
69 --kunitconfig=drivers/gpu/drm/
