By allowing the filter_glob parameter to be written to, it's possible to tweak the testsuites that will be executed on new module loads. 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.
