The idea here is the following - draw a uniform frame with blue color - grab crc for reference - put planes randomly on top with the same blue color - punch holes with black color into the primary framebuffer - ideally the planes should cover these holes so that the output is the identical to reference crc - composite all with one ioctl call - grab crc and verify that the reference crc is equal - repeat this for dozen iterations to maximize coverage v4: For atomic test enable crc capturing before entering into a iteration loop. After each iteration, check that page flip didn't take no more than 1 vblank, fetch all crc's and check the values. Introduce new command line parameter for the number of iterations. The test run from 1 to 256 iterations. v3: Cleanup by removing separate plane array For atomic, pass DRM_MODE_PAGE_FLIP_EVENT Grab crc by using igt_pipe_crc_get_crc instead of igt_pipe_crc_collect_crc Rename nplanes variable to max_planes To optimize test execution, run iterations after the modeset v2: Keep a logfile on random number seeds per subtest that are not skipped due to unmet test requirements Signed-off-by: Mika Kahola --- tests/Makefile.sources | 1 + tests/kms_plane_multiple.c | 475 +++++++++++++++++++++++++++++++++++++++++++++ 2 files changed, 476 insertions(+) create mode 100644 tests/kms_plane_multiple.c diff --git a/tests/Makefile.sources b/tests/Makefile.sources index 6d081c3..ffd59c1 100644 --- a/tests/Makefile.sources +++ b/tests/Makefile.sources @@ -105,6 +105,7 @@ TESTS_progs_M = \ kms_pipe_color \ kms_pipe_crc_basic \ kms_plane \ + kms_plane_multiple \ kms_properties \ kms_psr_sink_crc \ kms_render \ diff --git a/tests/kms_plane_multiple.c b/tests/kms_plane_multiple.c new file mode 100644 index 0000000..a18cdff --- /dev/null +++ b/tests/kms_plane_multiple.c @@ -0,0 +1,475 @@ +/* + * Copyright © 2016 Intel Corporation + * + * Permission is hereby granted, free of charge, to any person obtaining a + * copy of this software and associated documentation files (the "Software"), + * to deal in the Software without restriction, including without limitation + * the rights to use, copy, modify, merge, publish, distribute, sublicense, + * and/or sell copies of the Software, and to permit persons to whom the + * Software is furnished to do so, subject to the following conditions: + * + * The above copyright notice and this permission notice (including the next + * paragraph) shall be included in all copies or substantial portions of the + * Software. + * + * THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR + * IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF MERCHANTABILITY, + * FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT.
