+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.
