That's an updated version of my previous KUnit RFC series: https://patchwork.freedesktop.org/series/110481/ While the RFC series added support for live and perf, let's start with mock, as running tests in bare metal is not the current focus of KUnit. So, basically patch 1 was changed to export just mock functions, and the bare metal patches got removed from this version. As before, running KUnit on i915 driver requires the --arch parameter: ./tools/testing/kunit/kunit.py run --arch=x86_64 --kunitconfig=drivers/gpu/drm/i915/selftests/ --jobs=`nproc --all` [13:18:40] Configuring KUnit Kernel ...
