I haven't had time to test further, but with all 5 applied on top of deathsimple drm-fixes I loose output to TV as soon as I startx. It worked in fbcon before starting X, but not switching vt after. My TV according to edid-decode does support deep colour. Nothing obvious to see in dmesg/Xorg.0.log and xrandr --verbose looked like it was on, tried some different modes, but nothing. R9 270X
