KUnit[2][3] is a unified test framework that provides helper tools, simplifying their development and execution. Using an x86-64 machine it's possible to run tests in the host's kernel natively using user-mode Linux[4] (aka UML), which simplifies usage in a wide variety of scenarios, including integration to CI. As the tool's adoption widens into graphics testing territory, I and LKCamp members figured it would be important to support it in IGT, as it's a core tool for GPU drivers maintainers. I have then added KUnit support into IGT mainly following the KTAP specs, and it can be tested using patch 4/4 in this series together with a DRM selftests patch series available at [5]. Changes since v1: - Major rework of parsing function structure: - It is not longer recursive - Adapt kselftests functions and structs to be used with KUnit - Switch DRM selftests to KUnit parsing as they're updated in the kernel - Replace AMD KUnit tests by DRM selftests [1]: https://groups.google.com/g/kunit-dev/c/YqFR1q2uZvk/m/IbvItSfHBAAJ [2]: https://kunit.dev [3]: https://docs.kernel.org/dev-tools/kunit/index.html [4]: http://user-mode-linux.sourceforge.net [5]: https://lore.kernel.org/all/20220708203052.236290-1-maira.canal@usp.br/ Isabella Basso (4): lib/igt_kmod: rename kselftest functions to ktest lib/igt_kmod.c: check if module is builtin before attempting to unload it lib/igt_kmod: add compatibility for KUnit tests: DRM selftests: switch to KUnit lib/igt_kmod.c | 315 +++++++++++++++++++++++++++++++++++++++++-- lib/igt_kmod.h | 14 +- tests/drm_buddy.c | 7 +- tests/drm_mm.c | 7 +- tests/kms_selftest.c | 12 +- 5 files changed, 329 insertions(+), 26 deletions(-) -- 2.37.2
