Passthrough RX580

Hi Unraiders,

 

I have been struggling with getting my msi rx580 oc to passthrough to my VM windows 10 PC. I read through the boards to get the best configuration, esp since my GPU supports UEFI, it appears. When switching from VNC, to my RX580 for video and sound, my screen goes dark, forcing my to reboot the system to get my monitor back.

 

It appears I shouldnt need 2 GPUs to accomplish passthough. I downloaded the rom for the RX580 from techpowerup. Also switched on/off hyperv and used with no rom. Any ideas what I am missing here?

 

I attached my VM config below:

 

thanks for the help, I really like unraid thus far.

I'll be keeping an eye on this post.  I've just purchased a RX570 and having the same issue.  I've had some luck with Linux VMs but not Windows.

to add more to my post system detail wise, see attached.

 

Virtualization and IOMMU are enabled on the host.

Unraid v6.7.2

 

Also rx580 is in it's own IOMMU group (group 15)

after executing and getting the black screen, looking at the error logs I get the below:

 

Any ideas are appreciated, I hope to get a second set of eyes to see whats wrong.

Also known as AMD reset bug. Some people with 5xx or the vega cards have that issue. If you search the forums you will find a couple reports. The card is only able to initialise once and can't be reset. Only a server reboot fixes this in most cases. Some people reported to not passthrough the audio part of the card works, for others using Q35 fixes it and for some it worked with passing through a GPU BIOS for this card. Another guy reported booting unraid in legacy mode vs uefi worked for him. Unfortunately there isn't a one click solution.
