Hyper-V PCIe Passthrough of GPU working (but not 100%)

I have managed to be able to passthrough a PCIe GPU (AMD RX580) into a Windows 10 Guest on a Windows Server 2016 Standard host.

The problem is that whenever the GPU will be used this error throws up:

The driver was installed through Windows update

The PCIe passthrough was done using Powershell (Administrator):

1. Set-VM -Name "Parsec" -AutomaticStopAction TurnOff
2. Dismount-VmHostAssignableDevice -LocationPath "PCIROOT(0)#PCI(0301)#PCI(0000)" -force
3. Add-VMAssignableDevice -LocationPath "PCIROOT(0)#PCI(0301)#PCI(0000)" -VMName "Parsec"
4. Set-VM "Parsec" -GuestControlledCacheTypes $True -LowMemoryMappedIoSpace 2000MB -HighMemoryMappedIoSpace 8000MB

What could be missing here?

Solution 1:

please follow this tutorial here https://youtu.be/XLLcc29EZ_8?t=570

the script i used is below

$vm = "YOUR_VM_NAME_HERE"

Add-VMGpuPartitionAdapter -VMName $vm
Set-VMGpuPartitionAdapter -VMName $vm -MinPartitionVRAM 80000000 -MaxPartitionVRAM 100000000 -OptimalPartitionVRAM 100000000 -MinPartitionEncode 80000000 -MaxPartitionEncode 100000000 -OptimalPartitionEncode 100000000 -MinPartitionDecode 80000000 -MaxPartitionDecode 100000000 -OptimalPartitionDecode 100000000 -MinPartitionCompute 80000000 -MaxPartitionCompute 100000000 -OptimalPartitionCompute 100000000

Set-VM -GuestControlledCacheTypes $true -VMName $vm
Set-VM -LowMemoryMappedIoSpace 1Gb -VMName $vm
Set-VM –HighMemoryMappedIoSpace 32GB –VMName $vm
