The idea of the test is the following: - draw a blue screen with high resolution - enable a yellow plane, visible, in lower-left corner - set a new lower resolution mode (1024x768) that makes plane invisible - check from debugfs 'i915_display_info' that the plane is invisible - switch back to higher resolution mode - check from debugfs 'i915_display_info' that the plane is visible again - repeat number of iterations, default 64 Signed-off-by: Mika Kahola --- tests/Makefile.sources | 1 + tests/kms_plane_lowres.c | 424 +++++++++++++++++++++++++++++++++++++++++++++++ 2 files changed, 425 insertions(+) create mode 100644 tests/kms_plane_lowres.c diff --git a/tests/Makefile.sources b/tests/Makefile.sources index debe3df..9ebdc44 100644 --- a/tests/Makefile.sources +++ b/tests/Makefile.sources @@ -109,6 +109,7 @@ TESTS_progs_M = \ kms_pipe_crc_basic \ kms_plane \ kms_plane_multiple \ + kms_plane_lowres \ kms_properties \ kms_psr_sink_crc \ kms_render \ diff --git a/tests/kms_plane_lowres.c b/tests/kms_plane_lowres.c new file mode 100644 index 0000000..6735a3b --- /dev/null +++ b/tests/kms_plane_lowres.c @@ -0,0 +1,424 @@ +/* + * 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.
