25 Does KUnit support running on architectures other than UML?
30 For the most part, the KUnit core framework (what we use to write the tests)
33 module is loaded. However, there is infrastructure, like the KUnit Wrapper
34 (``tools/testing/kunit/kunit.py``) that might not support some architectures
35 (see :ref:`kunit-on-qemu`).
37 In short, yes, you can run KUnit on other architectures, but it might require
