* Documentation: Kunit: add MODULE_LICENSE to sample codeTakashi Sakamoto2023-05-311-0/+2
| | | | | | | | | | | The sample code has Kconfig for tristate configuration. In the case, it could be friendly to developers that the code has MODULE_LICENSE, since the missing MODULE_LICENSE brings error to modpost when the code is built as loadable kernel module.

* Documentation: kunit: Modular tests should not depend on KUNIT=yGeert Uytterhoeven2023-05-081-1/+4
| | | | | | | | | | | | | | When the documentation was updated for modular tests, the dependency on "KUNIT=y" was forgotten to be updated, now encouraging people to create tests that cannot be enabled when the KUNIT framework itself is modular. Fix this by changing the dependency to "KUNIT". Document when it is appropriate (and required) to depend on "KUNIT=y".

| | | | | | | | | | | | | | | | | | | | | | | The "How Do I Use This" section of index.rst and "Next Steps" section of start.rst were just copies of the table of contents, and therefore weren't really useful either when looking a sphinx generated output (which already had the TOC visible) or when reading the source (where it's just a list of files that ls could give you). Instead, provide a small number of concrete next steps, and a bit more description about what the pages contain. This also removes the broken reference to 'tips.rst', which was previously removed.

| | | | | | | | | | | | | | | | | | Commit ddbd60c779b4 ("kunit: use --build_dir=.kunit as default") changed the default --build_dir, which had the side effect of making `.kunitconfig` move to `.kunit/.kunitconfig`. However, the first few lines of kunit/start.rst never got updated, oops. Fix this by telling people to run kunit.py first, which will automatically generate the .kunit directory and .kunitconfig file, and then edit the file manually as desired.

* | kunit: tool: reconfigure when the used kunitconfig changesDaniel Latypov2021-12-131-4/+4
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Problem: currently, if you remove something from your kunitconfig, kunit.py will not regenerate the .config file. The same thing happens if you did --kunitconfig_add=CONFIG_KASAN=y [1] and then ran again without it. Your new run will still have KASAN. The reason is that kunit.py won't regenerate the .config file if it's a superset of the kunitconfig. This speeds it up a bit for iterating. This patch adds an additional check that forces kunit.py to regenerate the .config file if the current kunitconfig doesn't match the previous one. What this means: * deleting entries from .kunitconfig works as one would expect * dropping a --kunitconfig_add also triggers a rebuild * you can still edit .config directly to turn on new options We implement this by creating a `last_used_kunitconfig` file in the build directory (so .kunit, by default) after we generate the .config. When comparing the kconfigs, we compare python sets, so duplicates and permutations don't trip us up. The majority of this patch is adding unit tests for the existing logic and for the new case where `last_used_kunitconfig` differs.

There are several things that aren't nailed down (in-tree .kunitconfig's), or partially broken (GCOV on UML), but having them documented, warts and all, is better than having nothing. This covers a bunch of the more recent features * kunit_filter_glob * kunit.py run --kunitconfig * slightly more detail on building tests as modules * CONFIG_KUNIT_DEBUGFS By my count, the only headline features now not mentioned are the KASAN integration and KernelCI json output support (kunit.py run --json). And then it also discusses how to get code coverage reports under UML and non-UML since this is a question people have repeatedly asked. Non-UML coverage collection is no different from normal, but we should probably explicitly call this out. As for UML, I was able to get it working again with two small hacks.* E.g. with CONFIG_KUNIT=y && CONFIG_KUNIT_ALL_TESTS=y Overall coverage rate: lines......: 15.1% (18294 of 120776 lines) functions..: 16.8% (1860 of 11050 functions) Note: this doesn't document --alltests since this is not stable yet. Hopefully being run more frequently as part of KernelCI will help... *Using gcc/gcov-6 and not using uml_abort() in os_dump_core(). I've documented these hacks in "Notes" but left TODOs for brendanhiggins@google.com who tracked down the runtime issue in GCC. To be clear: these are not issues specific to KUnit, but rather to UML.
