<pre>The test tries to test flip to y-tiling. For some, yet unknown reason, the
modeset pruned out the default mode
[drm:drm_mode_debug_printmodeline] Modeline "3840x2160": 60 533250 3840 3888
3920 4000 2160 2163 2168 2222 0x48 0x9
and leaving an interleaved mode as first acceptable mode as
[drm:drm_mode_debug_printmodeline] Modeline "1920x1080i": 60 74250 1920 2008
2052 2200 1080 1084 1094 1125 0x40 0x15
In this case, kernel actually does a right thing by returning -EINVAL as y/yf
tiling is not supported for interlaced modes.</pre>
