Thanks, I wasn't aware of that. The old overdrive functionality indeed works with amdgpu.dpm=1 on 4.16. However, it doesn't on 4.17. And wattman functionality doesn't work at all; pp_od_clk_voltage prints nothing and doesn't accept anything. Is wattman even implemented for CI? Also, do you consider enabling amdgpu.dpm for CI by default? I found the big advantage that the VRAM/MC is finally back to the lower dpm state in idle while driving a WQHD 144 Hz monitor. That saves solid 40 Watts on desktop usage.
