This seems real low. Screens run at usuall 50-60Hz, which means you just allow for a few seconds. I'd say for a normal validation run timing it to be 1 second (for each subtest) is a reasonable start. But for the knob we probably want to make this virtually unlimited, e.g. -1 == never stop. This would be useful for chasing hard-to-reproduct underruns and errors: Run testcase with unlimited iterations, it will die as soon as the first error shows up. Then try with next hack/debug trick until the test survives for hours and it all looks good ;-) For the testcode itself I think it'd be good if at least Ville and Maarten review it, since this will be the groundwork for adding all kinds of atomic tests (rotation, yuv, scaling, anything else really). -Daniel > > 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 <mika.kahola@intel.com> > --- > 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.

On error, ret < 0 and errno is printed. I'm not sure what you're trying to accomplish here. This should probably be igt_assert(ret == sizeof(*e)); The timeout is set after the read as well, which is weird too.

This is a testcase with multiple planes. 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 <mika.kahola@intel.com> --- tests/Makefile.sources | 1 + tests/kms_plane_multiple.c | 475 +++++++++++++++++++++++++++++++++++++++++++++ 2 files changed, 476 insertions(+) create mode 100644 tests/kms_plane_multiple.c
