kunit: test: add KUnit test runner core Add core facilities for defining unit tests; this provides a common way to define test cases, functions that execute code which is under test and determine whether the code under test behaves as expected; this also provides a way to group together related test cases in test suites (here we call them test_modules). Just define test cases and how to execute them for now; setting expectations on code will be defined later.

kunit: allow kunit to be loaded as a module Making kunit itself buildable as a module allows for "always-on" kunit configuration; specifying CONFIG_KUNIT=m means the module is built but only used when loaded. Kunit test modules will load kunit.ko as an implicit dependency, so simply running "modprobe my-kunit-tests" will load the tests along with the kunit module and run them.

kunit: add kunit.filter_glob cmdline option to filter suites E.g. specifying this would run suites with "list" in their name. kunit.filter_glob=list* Note: the executor prints out a TAP header that includes the number of suites we intend to run. So unless we want to report empty results for filtered-out suites, we need to do the filtering here in the executor. It's also probably better in the executor since we most likely don't want any filtering to apply to tests built as modules. This code does add a CONFIG_GLOB=y dependency for CONFIG_KUNIT=y. But the code seems light enough that it shouldn't be an issue. For now, we only filter on suite names so we don't have to create copies of the suites themselves, just the array (of arrays) holding them. The name is rather generic since in the future, we could consider extending it to a syntax like: kunit.filter_glob=<suite_glob>.<test_glob> E.g. to run all the del list tests kunit.filter_glob=list-kunit-test.*del* But at the moment, it's far easier to manually comment out test cases in test files as opposed to messing with sets of Kconfig entries to select specific suites. So even just doing this makes using kunit far less annoying.

kunit: add kunit.enable to enable/disable KUnit test This patch adds the kunit.enable module parameter that will need to be set to true in addition to KUNIT being enabled for KUnit tests to run. The default value is true giving backwards compatibility. However, for the production+testing use case the new config option KUNIT_DEFAULT_ENABLED can be set to N requiring the tester to opt-in by passing kunit.enable=1 to the kernel.
