From 12e34d8c909a6bd203722a92a019693fec779db6 Mon Sep 17 00:00:00 2001 From: Mika Kahola Date: Wed, 23 Nov 2016 11:19:37 +0200 Subject: tests/kms_plane_lowres: Plane visibility after atomic modesets Testcase for plane visibility after atomic modesets. 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 v2: allow test to be run on non-Intel drivers (Daniel) moved test for plane visibility to as helper function (Daniel) moved get_vblank() function to be part of helper functions (Daniel) rename 'tiling' parameter as 'modifier' (Daniel) select a mode from a list so that the plane should be invisible. use default 1024x768 mode only as a fallback if decent mode has not been found (Daniel) add tiling MODE_NONE (Daniel) v3: draw as many overlay planes as the platform supports + cursor plane on top of each other on lower-left corner skip the test if i915_display_info file is not available test plane visibility with igt_assert_plane_visibility() function drop option for multiple test iterations (Daniel Vetter) v4: switch 'for_each_connected_output()' to 'for_each_valid_output_on_pipe()' skip Y and Yf tiling for generations older than 9 (Maarten) Cc: Daniel Stone Cc: Maarten Lankhorst Reviewed-by: Maarten Lankhorst Signed-off-by: Mika Kahola --- tests/kms_plane_lowres.c | 348 +++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 348 insertions(+) create mode 100644 tests/kms_plane_lowres.c (limited to 'tests/kms_plane_lowres.c') diff --git a/tests/kms_plane_lowres.c b/tests/kms_plane_lowres.c new file mode 100644 index 00000000..93aefdaa --- /dev/null +++ b/tests/kms_plane_lowres.c @@ -0,0 +1,348 @@ +/* + * 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.
