--- Comment #8 from Stanislav Lisovskiy <stanislav.lisovskiy at intel.com> ---
After discussing with Ville to me it looks either there might be an issue with
watermark calculation algorithm(I will check with bspec if there is a mistake)
and also there is an issue with drm_mode_addfb2 as userspace attempts to use Y
Tiling for buffer object, but without using explicit FB modifiers, which leads
to an error. It seems to fall back to X Tiling which doesn't exceed watermarks,
only once we replug the display.
