[SOLVED] Intel Arc A310 GPU not visible on `Add Device` menu

[hhharsha36]

I am running latest Proxmox version 8.2 on a Minisforum UM890 device. I have connected Razer Core X with Intel Arc A310 GPU via the Thunderbolt port.

I have successfully configured Proxmox to recognize Razer Core X eGPU device using `bolt` package and even authorized it using boltctl enroll [UUID] and boldctl authorize [UUID] commands.

root@proxmox:~# boltctl list

Next, I attempted to make Proxmox recognize Arc GPU using this guide. But unfortunately I was unable to make Proxmox recognize the connected GPU.


Below are the information from various commands which might be helpful to diagnose the issue:

root@proxmox:~# dmesg | grep -e DMAR -e IOMMU

Note: Everything works fine when I connect the eGPU with Intel Arc GPU attached a Windows machine

Please let me know if you need any further information from my side. Any help to help in resolving the issue is much appreciated.

I found the fix. There is a setting in MinisForum UEFI under advanced settings -> PCI option which is responsible for PCIe passthrough that is disabled by default, I forgot the name of the exact option name to toggle.

Enabling it fixed the issue.
