I've finally been able to test the problem you have reported on the Lager board. There is a new issue introduced in the current merging window that completely breaks HDMI output on Lager. I have posted a fix to the dri-devel and linux- renesas-soc mailing lists under the subject "[PATCH] drm: rcar-du: Link HDMI encoder with bridge". I will make sure that it lands in v4.8 (hopefully in v4.8-rc1, but it might have to wait for v4.8-rc2). With the fix applied to Linus' latest master branch (the commid ID I used is f7b32e4c021fd788f13f6785e17efbc3eb05b351) HDMI output works properly on Lager for me. Running your test application displays the image correctly on my screen. Could you check whether you can reproduce the problem with the latest kernel ? -- Regards, Laurent Pinchart
