[Intel-gfx] [PATCH i-g-t 5/5] tests/kms_test_only: Validate TEST_ONLY correctness against full atomic commit
Mika Kahola

Fri Dec 30 12:00:41 UTC 2016
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.
