AMD iGPU passthrough causes damage to HDD

[PavelGolyakov]

Hi,
I have a mini pc with the following specs:
AMD Ryzen 5 4500U with Radeon Graphics
32GB ram
256GB SSD

my problem is I can't get the integrated GPU to passthrough.
I have made all the steps some different instructions, the last one is here https://github.com/isc30/ryzen-7000-series-proxmox

But if I added the PCI Device to my VM on Win and tried to run, my HDD stopped working and I received an error
"TASK ERROR: unable to activate storage 'other' - directory is expected to be a mount point but is not mounted: '/mnt/pve/other'"

'other' is the name of the directory of my HDD.

I have tried to use my nvme disc instead of HDD, and this resulted in bad sectors on the nvme.

Any Ideas?

Thank you.

You facing to IOMMU group isolation.

Many small PCs cannot passtrough because yall your PC components are in the SAME IOMMU group. Then, when trying tio enable passtrough, vfio is loaded on all IOMMU peripherical attached device.
No solution for this at this time

Does it mean there are no ways to have a graphical interface using hdmi if I have a proxmox on my mini PC?

And i see some IOMMU group

Yeah from IOMMU pic you can see basically everything on your MB is under group 6.
PCIe passthrough is actually IOMMU group passthrough, so you need another MB, preferably server boards with proper IOMMU group segmentation.

That's why I keep telling people don't mess up with server-grade virtualization when you only got pathetic consumer components at hands.

you can even do that you want, but, not via passtrough. Check XDMCP Protocol.

any chanse to have more detailes about it?

it's permit to launch remote graphical session over your local computer (here, your proxmox console). When done over a virtual network, this is not a bad choice
