unraid 6900xt problem ?

[Ricotta Elmar]

hello guys, i have been trying to get a Sapphire 6900xt se  to work in m unriad system

 

my current system is

ryzen tr 3960x

aorus master trx40

64 gb ddr4 3200mhz

aorus 1080ti

 

i create a new vm with pass through 6900xt and nvme

dmesg https://clbin.com/BBk5J

vm https://clbin.com/DkNND

and a video

https://streamable.com/w6v8c2

 

maby someone here have clues

 

i put some older hardware together for a test pc with another unraid

 

r7 3700x

32gb ddr4 3600mhz

6900xt se

asus rog strix gaming-e x570

 

and there it works fine right out of the bat

vm https://clbin.com/vE6uf
dmesg https://clbin.com/oUFbA

 

maby someone is smart enough to help me with this

 

attachemtns are from the vm where the gpu works fine on and shows fine to compare to my current gigabyte where audio only show AMD (id)

The RX6### line has actually been praised for having issues like PCI_e reset fixed allowing better stability when attempting to pass them to VMs. So it looks like on your TR system I'd be led to believe it's a configuration or system conflict issue.

 

I'm not unRAID savvy but I've worked with QEMU/KVM & hardware pass-through. The VM is starting but it does look as though it's crashing probably as soon as Windows tries to load a driver into the card.

 

Are you connecting to the GPU physically or are you viewing it through the KVM console?

 

AMD-V looks enabled but did you enable IOMMU? It looks enabled but we have to start somewhere.

on a side note i found out that my GPU audio and video is spitted on the gigabyte vs the single iommu group like asus

 

this probably is the problem

yes iommu is enabled, but as i showed in post above, it spitted audio and video in separate iommu groups, and that probably cause the GPU to crash

 

and i have a display connected to the GPU a you saw in the video

You bring up a good point. Yes, normally the onboard audio component would want to be in the same IOMMU Group as the GPU core. In theory if they've been forced apart you should be able to pass it through anyway so long as you pass-through both IOMMU Groups. I don't think they have to stay in the same group.

 

Do check though that both are alone in their own groups and that neither are coupled with any other devices as this would further complicate things.

i dont get it,  well eyah both are passed through or so i hope they are, atleast for gpu i am use but the audio part witch the gigabyte dont see or read i dont know

So you've passed through both now and it's still not working?

 

I don't know about UnRAID but does it give you the option to pass through all components of the device instead of independently?

 

Lets say instead of passing them independently:

PCI Device: 4b:00.0 VGA
PCI Device: 4b:00.1 Audio

 

Will UnRAID let you do this:

PCI Device: 4b:00. VGA/Audio

 

By not designating the last digit in the Device Address the hypervisor assumes all devices within the Device Address are being passed through.

thanks , i already sloved it, by disable resizable bar ....

 

so far it works fine , took alot  support for something so simple
