This series is a continuation of Isabella's work on introducing
KUnit to IGT.
Sample drm_buddy output:
Starting subtest: drm_buddy_test
[thread:23835] TAP version 1
[thread:23835] Executing 6 tests in: drm_buddy
Starting dynamic subtest: drm_buddy-drm_test_buddy_alloc_limit

The issue of possibility of too many sublevels occurrence is solved
by name concatenation.

This aims at making IGT's structure more general to different kernel
testing frameworks such as KUnit, as they use a lot of the same
functionality.

This change makes `igt_kmod_unload_r` safer as it checks whether the
module can be unloaded before attempting it.
v2 -> v3:
- Fix commit message
- Make return value clearer

This adds functions for both executing the tests as well as parsing (K)TAP
kmsg output, as per the KTAP spec [1].
[1] https://www.kernel.org/doc/html/latest/dev-tools/ktap.html
v1 -> v2:
- refactor igt_kunit function and ktap parser so that we have only one
parser that we call only once (code size is now less than half the
size as v1)
- add lookup_value helper
- fix parsing problems
v2 -> v3:
- move ktap parsing functions to own file
- rename to ktap_parser
- get rid of unneeded pointers in igt_kunit
- change return values to allow for subsequent call to igt_kselftests if
needed
- add docs to parsing functions and helpers
- switch to line buffering
- add line buffering logging helper
- fix kunit module handling
- fix parsing of version lines
- use igt_subtest blocks to improve output handling on the CI
- fix output handling during crashes
Signed-off-by: Isabella Basso <isabbasso@riseup.net>
v3 -> v4:
- handle igt_ktap_parser fail with IGT_EXIT_ABORT code
v4 -> v5:
- added missing newlines in igt_warn
- removed setvbuf

- drm_buddy|drm_mm: fallback to igt_kselftests if igt_kunit failed
with code other than IGT_EXIT_ABORT
- kms_selftest: move igt_kunit tests to separate subtests
- kms_selftest: fallback to igt_kselftests if all subtests failed
v2 -> v3:
- expose all subtests

To: igt-dev
The ktap parser should be listening and parsing messages as the tests
are executed, and not after the end of module load.
v1 -> v2:
- fix coding style
- remove usleep
- add error check logic
- follow the structure of igt_kselftests more closely
v2 -> v3:
- fixed sublevel issues by rewriting tap parser flow
v3 -> v4:
- fixed delimiter
- squashed lib/igt_kmod: fix nesting igt_fixture in igt_subtest
Fix the following issue:
$ ./build/tests/drm_buddy
Starting subtest: all-tests
nesting igt_fixture in igt_subtest is invalid
please refer to lib/igt_core documentation
- squashed lib/igt_kmod: place KUnit tests on a subtest
There's a hidden bug at KUnit implementation: as it doesn't
place tests inside a subtest, trying to use it with igt_main
causes a crash:
$ ./build/tests/drm_mm --list
skipping is allowed only in fixtures, subtests or igt_simple_main
please refer to lib/igt_core documentation
drm_mm: ../lib/igt_core.c:437: internal_assert: Assertion `0' failed.
Received signal SIGABRT.

#15 [_start+0x25]
Fix it by using igt_subtests() before actually implememnting
KUnit logic.
After the patch, it should now report subtests:
$ ./build/tests/drm_mm --list
all-tests

When multiple KUnit tests are called by the same program, it is
interesting to group them with a name. This would allow IGT
namespace to better refer to the KUnit tests and will give some
filtering capability to it.
After those changes, the IGT kUnit tests will be better named:
$ for i in kms_selftest drm_buddy drm_mm; do echo $i:; build/tests/$i --list; echo; done
kms_selftest:
drm_cmdline
drm_damage
drm_dp_mst
drm_format_helper
drm_format
framebuffer
drm_plane
all-tests
drm_buddy:
all-tests
drm_mm:
all-tests

Hmm.... not being able to read from /dev/kmsg doesn't seem a reason for
skipping the test.
IMO, the test should be skipped only if:
1. The Kernel is not compiled with KUnit support;
2. The KUnit test was not compiled.
Errors for all other conditions should be considered as failures.
Now, I'm not sure what would be the proper way to test for such
skip condition. I suspect you could check the error code at
igt_kmod_load(), calling igt_skip() if it returns -ENOENT,
e. g. on this part of __igt_kunit():
/* The KUnit module is required for running any KUnit tests */
if (igt_kmod_load("kunit", NULL) != 0 ||
kmod_module_new_from_name(kmod_ctx(), "kunit", &kunit_kmod) != 0) {
igt_warn("Unable to load KUnit\n");
igt_fail(IGT_EXIT_FAILURE);
}
is_builtin = kmod_module_get_initstate(kunit_kmod) == KMOD_MODULE_BUILTIN;
results = ktap_parser_start(f, is_builtin);
if (igt_kmod_load(module_name, opts) != 0) {
igt_warn("Unable to load %s module\n", module_name);
ret = ktap_parser_stop();
igt_fail(IGT_EXIT_FAILURE);
}
This could be replaced by something similar to:
err = igt_kmod_load("kunit", NULL);
igt_skip_on(err == ENOENT, "KUnit not supported");
igt_fail_on_f(err != 0, "Error %d when trying to load kunit", err);
if (kmod_module_new_from_name(kmod_ctx(), "kunit", &kunit_kmod) != 0) {
igt_warn("Unable to load KUnit\n");
igt_fail(IGT_EXIT_FAILURE);
}
is_builtin = kmod_module_get_initstate(kunit_kmod) == KMOD_MODULE_BUILTIN;
results = ktap_parser_start(f, is_builtin);
err = igt_kmod_load(module_name, opts)
igt_skip_on(err == ENOENT, "Module %s not found", module_name);
if (err) {
igt_warn("Error %d when trying to load %s module\n", err, module_name);
ret = ktap_parser_stop();
igt_fail(IGT_EXIT_FAILURE);
}
In order to explicitly check for (1) and (2).

Mauro

Why do we reinvent the wheel instead of following the pattern from
igt_kselftest()? We used to follow it, before the whole igt_kunit() body was
put under igt_subtest_with_dynamic() (patch 6/8 of v5, then squashed with 5/5,
IIRC). That forced us to introduce a series of changes inside igt_kunit(),
which we now contest. Was that really necessary?

Nobody is talking about reinventing the wheel. Selftests and KUnit tests
are executed on different ways.
For selftests, the same driver that was loaded before needs to be unloaded
and re-probed with a different argument.
For KUnit tests, a different module will be loaded, if the Kernel was
compiled with KUnit support for a given test suite.
Looking at KUnit modprobe time, if a module doesn't load because the file
doesn't exist (-ENOENT error), it means that:
- for KUnit: the KUnit module was not compiled.
- for selftests: this is really unlikely to happen, as all other
previous IGT tests depend on having the driver module loaded.
So, no need for any explicit check for this specific condition.

This has nothing to do with using (or not) a dynamic IGT subtest.
It is related to how to report IGT errors while trying to run KUnit
tests.
Without this patch, every kind of errors will produce a failure;
after this patch, they'll all produce a skip.
IMO, what it is needed is to split KUnit errors on two different
categories:
1. "real" errors while running KUnit (like troubles reading dmesg);
2. the KUnit module to be modprobed doesn't exist.
for (1), igt_fail() is the proper error handling.
For (2), igt_skip() is the right error handling, as the Kernel under
tests doesn't have what it is needed to run KUnit, as the module was
not compiled.

It has. As soon as you enter an igt_subtest or igt_subtest_with_dynamic
section, your inform users (CI) that the subtest execution started. And, you
can't call return, only igt_success(), or igt_skip()/igt_fail() and friends,
form inside, while you can before.
The DRM selftests we are going to update are now using igt_kselftest(), which
calls return on some initial conditions not met, before the
igt_subtest_with_dynamic section is entered. CI expects that behavior, users
are used to it. We shouldn't change that only because we switch from an old
underlying kernel selftest format to a new shiny one, I believe, unless we are
able to prove that there was something wrong with that former approach, or we
can explain why it no longer fits into the kunit variant.

Yes, that was wrong, and thank you Dominik for fixing this. But plaese also
note that the badness was mostly caused by ad-hoc corrections to igt_kunit()
body, forced by putting it as a whole insinde igt_subtest_with_dynamic()
section while it was not ready for that. IOW, my objections don't apply to
this patch specifically, but rather the the whole series that started from
igt_kunit() trying to provide the same used experience as igt_ksleftest(),
then that approach being destroyed with patches subsequently added to the
series.

I agree that troubles reading dmesg are critical to kunit variants, while they
were negligible for old selftests, hence their handling specifically must now
be different, but for me such a difference is not a sufficient justification
for killing the whole igt_ksleftest() error handling pattern and inventing a
new one from scratch.

Well, igt selftest excecution also calls igt_subtest_with_dynamic().
However, on kunit, the tests start running during modprobe time, so
igt_subtest_with_dynamic() needs to be called before that. Maybe some
validations could happen earlier, but the most important one (checking
that the module exists) happens when the module is probed, which is the
same call that starts the test.

No. Since 2022 - specifically, since those commits:
- 932da861956a ("drm: selftest: convert drm_buddy selftest to KUnit")
- fc8d29e298cf ("drm: selftest: convert drm_mm selftest to KUnit")
those tests don't work anymore, as upstream removed support for selftest,
in favor of KUnit. So, those tests currently do nothing.
We are changing because those tests are currently broken on IGT. That
is the reason why we need KUnit support for such tests.

Yes, there's something wrong with the former approach: the tests are
currently broken, as upstream moved on.

The same as it was happening on modules that implemented the old DRM i915-
alike selftests, and still happens on i915 selftests. AFAICT, kunit modules
are not any different in that aspect.

In my opinion -- no, those tests currently skip, which is different from doing

Are you saying that error handling in igt_ksleftest() is broken? In my
opinion, i915 selftests successfully executing on CI now and again, as well as
the outdated DRM selftests successfully skipping, prove something different.
I believe that igt_kunit() that follows as closely as possible the pattern of
how igt_kselftest() is handling unmet conditions and errors, with full respect
to real differences between kunit and i915-like selftests, would be the best
solution.

IGT tests are broken, as IGT is not able anymore to execute drm_buddy and
drm_mm unit tests. This series fix it.

No, I'm saying that drm core tests are broken on IGT, because drm core doesn't
support the legacy selftest infrastructure since 2022, and IGT is currently
missing kUnit support.
On other words, IGT won't run such tests *even* if the Kernel is build with
support for DRM core tests.

I'm not saying anthing different, but KUnit and selftest executions are
different:
- with selftest, the module loads asynchronously. After the module is
loaded with success, the probe() method will be called and the tests
will run.
It means that it is possible to first load the driver and then run
igt dynamic subtest logic, parsing the results from dmesg.
- with KUnit, the unit tests will run synchronously at modprobe time.
So, when modprobe() finishes execution, all KUnit tests were already
executed - and if the Kernel crashes on a KUnit test - results will be
lost.
It means that all steps needed to execute KUnit should be handled
before modprobing, including starting a thread to capture dmesg
results during modprobe time. So, igt dynamic subtests should be created
before calling modprobe() function.
due to such difference, igt_subtest_with_dynamic() should be called
before modprobe(), and, if something goes wrong on that time - for instance
if the module doesn't exist and returns EENOENT - IGT needs to use
igt_skip() or igt_fail().

Mauro

Please have a look at drivers/gpu/drm/i915/i915_module.c, see how
i915_mock_selftests() is called, then reevaluate your opinion on kunit doing
that in a different way.
