++KUnit Tests
++===========
++
++The VC4 Driver uses KUnit to perform driver-specific unit and
++integration tests.
++
++These tests are using a mock driver and can be ran using the
++command::
++	./tools/testing/kunit/kunit.py run \
++		--kunitconfig=drivers/gpu/drm/vc4/tests/.kunitconfig \
++		--cross_compile aarch64-linux-gnu- --arch arm64
++
++Parts of the driver that are currently covered by tests are:
++ * The HVS to PixelValve dynamic FIFO assignment, for the BCM2835-7
++   and BCM2711.
