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 below, on either arm or arm64 architectures,

.. code-block:: bash

	$ ./tools/testing/kunit/kunit.py run \
		--kunitconfig=drivers/gpu/drm/vc4/tests/.kunitconfig \
		--cross_compile aarch64-linux-gnu- --arch arm64

Implementation Notes

This generated page is the file-by-file coverage layer; curated subsystem chapters should link here when they synthesize a multi-file control flow.
Core OS pages should be promoted from atlas-only to deep-reviewed when they explain data structures, invariants, locking, lifecycle, and C implementation snippets.
Driver-family pages are intentionally pattern-oriented unless they are part of the selected PCIe/NVMe representative device path.
