The bug is still present in 4.18.0-rc2 (git as of an hour ago). Total scandal. Works on my system right now, though, since I stuffed bpc = 8; before switch (bpc) in drivers/gpu/drm/amd/display/amdgpu_dm/amdgpu_dm.c and compiled. Perhaps a temporary fix could be a kernel parameter such as amdgpu.8bit=1 Or the code could check if the connector is HDMI and resolution is 4k and set bpc=8 if that is true. I suspect it would be a bit bad if 4.18 is released with this problem, btw. It breaks 4k60Hz over HDMI on both my 4K's so it probably applies to most of the 4K monitors out there. Thank you for reading all of this. Please fix my bug.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
