This test case adds TEST_ONLY flag to the following test cases to test
atomic commit correctness.
- kms_plane_multiple
- kms_atomic_transitions
- kms_plane_scaling
- kms_rotation_crc
The test randomly selects one of the above test cases and tests atomic
commit. If the test fails with TEST_ONLY flag the real deal atomic commit
is executed and the outcome is verified.
For: VIZ-6956
Mika Kahola (5):
tests/kms_plane_multiple: Add TEST_ONLY flag
tests/kms_atomic_transition: Add TEST_ONLY flag
tests/kms_plane_scaling: Add TEST_ONLY flag
tests/kms_rotation_crc: Add TEST_ONLY flag
tests/kms_test_only: Validate TEST_ONLY correctness against full
atomic commit

From: Mika Kahola @ 2016-12-30 12:00 UTC (permalink / raw)
To: intel-gfx
This test case adds TEST_ONLY flag to the following test cases to test
atomic commit correctness.
- kms_plane_multiple
- kms_atomic_transitions
- kms_plane_scaling
- kms_rotation_crc
The test randomly selects one of the above test cases and tests atomic
commit. If the test fails with TEST_ONLY flag the real deal atomic commit
is executed and the outcome is verified.
The test runs by default for 64 iterations.

Hey,
What does this test add?
Any test should pass with PASS. This test retrying failed test-only tests won't add much there. No test should ever fail.

But you can already compare test passes vs test fails. There's no need for a separate test because any test failing should already be investigated.
I don't think a test that tests another test is useful, we already have infrastructure for that. :-)

I would only pass ALLOW_MODESET for the TEST_ONLY case.

You still want to do some kind of pipe setup, else the state of the pipe will depend on what was set before it.
I'm not sure what you want the state to be though.

Other failures are fine? I would leave igt_display_commit_atomic here, it catches errors for you. :)

I'm pretty sure the legacy tests don't work with TEST_ONLY..

I think it's best to just list the tests twice, once normal and once with test-only in the test name?

So what should we do about this test? Would it be enough if we just add
these TEST_ONLY flag tests to these igt tests and forget this one that
just tests if the test was successful or not?

Yes. But we should also probably determine what we want to test.
Easiest might just be to do each commit twice, once with TEST_ONLY, followed by the same commit done normally.
Maybe we could create a test mode for this in igt core that can be toggled, that performs any atomic commit twice?
Plugging that in would be a whole lot less invasive, only adding a single line to each changed test.
