Correct. > Will it be necessary to write a little KUnit glue function for each > kselftest, or is there some other scheme in mind here? With the current framework it is necessary to write some glue code: * A stub .c file which #includes the existing kselftest source * A kbuild userprog Makefile * A custom KUnit function which calls kunit_uapi_run_kselftest() A more high-level scheme may come later, but so far I have not worked on that. It would be nice for example to build and run the tests for all ABIs supported by a kernel without a lot of manual code duplication. And maybe have some higher level helpers around declaring the tests. Thomas
