This makes it easier to run specific tests without having to reload kunit and provides a way to filter tests on real HW even if kunit is builtin. Example for xe driver: 1) Run just 1 test # echo -n xe_bo > /sys/module/kunit/parameters/filter_glob # modprobe -r xe_live_test # modprobe xe_live_test # ls /sys/kernel/debug/kunit/ xe_bo 2) Run all tests # echo \* > /sys/module/kunit/parameters/filter_glob # modprobe -r xe_live_test # modprobe xe_live_test # ls /sys/kernel/debug/kunit/ xe_bo xe_dma_buf xe_migrate xe_mocs For completeness and to cover other use cases, also change filter and filter_action to rw.
