That was what I had been trying but never did manage to get it working, my entire system would crash every time I tried to boot a VM that had the APU attached. Regarding the docker containers, I had found someone on the Plex forums who had managed to get hardware transcoding working in a plex docker container on a Ryzen 7 4700U APU. Here's the link to the thread. I've just installed their fork of the linuxserver.io plex docker container and HW transcoding isn't immediately working for me, but I do get a response when I run vainfo from the docker container console. Also, when I previously built the Unraid kernel with amdgpu support before it was officially supported, I manage to get hardware transcoding working in the linuxserver emby container, but didn't continue down this path due to VOBSUB subtitles forcing transcoding within Emby on a lot of my media. Hope this info is helpful.

Thanks for the help. This is my output from the same command (also running headless, I had previously just booted in GUI mode with a display for testing purposes). root@Marvin:~# ls -lR /dev/dri /bin/ls: cannot access '/dev/dri': No such file or directory root@Marvin:~# modprobe amdgpu root@Marvin:~# ls -lR /dev/dri /bin/ls: cannot access '/dev/dri': No such file or directory root@Marvin:~# lsmod | grep amdgpu amdgpu 4308992 0 gpu_sched 20480 1 amdgpu i2c_algo_bit 16384 1 amdgpu drm_kms_helper 163840 1 amdgpu ttm 73728 1 amdgpu drm 356352 4 gpu_sched,drm_kms_helper,amdgpu,ttm backlight 16384 3 video,amdgpu,drm i2c_core 45056 5 drm_kms_helper,i2c_algo_bit,amdgpu,i2c_piix4,drm root@Marvin:~# EDIT: Closing this report as it was my own mistake, not an unraid bug. I previously had my IOMMU group containing the APU bound to VFIO at boot, and had forgotten to disable this.
