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()' (Maarten) Cc: Daniel Stone <daniel@fooishbar.org> Cc: Maarten Lankhorst <maarten.lankhorst@linux.intel.com> Signed-off-by: Mika Kahola <mika.kahola@intel.com> --- lib/igt_kms.c | 161 ++++++++++++++++++++++ lib/igt_kms.h | 23 ++++ tests/Makefile.sources | 1 + tests/kms_plane_lowres.c | 344 +++++++++++++++++++++++++++++++++++++++++++++++ 4 files changed, 529 insertions(+) create mode 100644 tests/kms_plane_lowres.c
