I think my requirement is some what similar to futex repo. Currently I am trying to under it. But still I am facing some issues in generating my 2 executable using kselftests. Also I found that current document does not explain much about how to include new tests. My requirement is as follows: I have a sub folders for test. Example: tools/testing/selftests/<my folders>/<folder1> I have my own Makefile, and some set of C source files under folder1 I also have a test script under folder1, that tests 2 executable generated out of 7 C files. I wanted to know how to make use of selftest framework to generate these 2 executable, and also execute my script to run the test. I have already includes <my folders> in top level Makefile under selftests. TARGETS = <my folders> Do, I need to create another Makefile under <my folders> and invoke folder1/Makefile from there? Or is there another way? > > greg k-h _______________________________________________ Kernelnewbies mailing list Kernelnewbies@xxxxxxxxxxxxxxxxx https://lists.kernelnewbies.org/mailman/listinfo/kernelnewbies
