3) Any chance to support -cvddc and -mvddc on Linux for amdgpu-pro drivers?
3. Same here, please check since I can't use Linux with RX470. Nitro+ 4GB reflashed, GPU opts are loaded, but Mem Voltage set to 1000mV regardless of my settings. So all runs at 1000mV instead of 900-875. On windows I can undervolt and it preserved by drivers, on Linux still no-go.
If you are not able to find one single working tool to set voltages under Linux, why not just code it into BIOS if you already reflash it?
