57KUnit Tests
58===========
59
60The VC4 Driver uses KUnit to perform driver-specific unit and
61integration tests.
62
63These tests are using a mock driver and can be ran using the
64command below, on either arm or arm64 architectures,
65
66.. code-block:: bash
67
68	$ ./tools/testing/kunit/kunit.py run \
69		--kunitconfig=drivers/gpu/drm/vc4/tests/.kunitconfig \
70		--cross_compile aarch64-linux-gnu- --arch arm64
71
72Parts of the driver that are currently covered by tests are:
73 * The HVS to PixelValve dynamic FIFO assignment, for the BCM2835-7
74   and BCM2711.
