I want to setup a single GPU passthrough on my Arch system with my Sapphire Radeon 550.
IOMMU Group 16: 09:00.0 VGA compatible controller : Advanced Micro Devices, Inc. [AMD/ATI] Lexa PRO [Radeon 540/540X/550/550X / RX 540X/550/550X] [1002:699f] (rev c7) 09:00.1 Audio device : Advanced Micro Devices, Inc. [AMD/ATI] Baffin HDMI/DP Audio [Radeon RX 550 640SP / RX 560/560X] [1002:aae0]
I followed a lot of tutorials and I assume I created the hooks and qemu config correctly. When I boot up the screen goes black and the monitor goes to standby. No signal.
I checked the logs and it seems that I cannot unload the amdgpu
sudo modprobe -r amdgpu modprobe: FATAL: Module amdgpu is in use.
There are other modules using the amdgpu. But I’m not able to unload these modules as well.
