Beelink S12 Mini Pro - Proxmox iGPU passthrough not working

Sandbo

Hi,


Thanks for the forum and it has been informative.

Recently I purchased a S12 Mini Pro with an Intel N100 CPU in hope of using it with Proxmox and a Windows 11 VM Guest.
I have lots of experience passing AMD/Nvidia GPUs in the past couple years over the ETH mining craze, but I am new to GPU passthrough when it comes to an Intel iGPU, and unfortunately things did not work so far for me, so it would be great if you can share your experience on this particular setup.

I have tried kernel 5.15 and 6.2, with the necessary kernel options to enable IOMMU (and confirmed later in console), loading the vfio modules and also blocking the host from accessing the GPU with drivers blacklist and kernel command (so now I don't see past post in Proxmox boot).

However, while I can pass the iGPU and install the Intel GPU driver, it always
1. End up showing code 43 in the driver. It seems the host was not able to fully give up the GPU.
2. No video output is observed from the two HDMI ports of the machine

I have spent a couple days trying all I knew but not having any luck.
Any ideas will be much appreciated.

Hello, you can use SRIOV for straight-through core display

@Lyc Could you please provide detailed steps how to enable Video passthrough on Proxmox?

To enable Video passthrough on Proxmox, you can follow these steps:
Log in to the Proxmox web interface.
Click on the "Nodes" tab and select the node where you want to enable Video passthrough.
Click on the "Hardware" tab and then click on "PCI Devices".
Find the graphics card you want to enable Video passthrough for and click on the "Edit" button.
In the "Edit PCI Device" dialog, select the " Passthrough" checkbox and click "OK".
Restart the Proxmox node to apply the changes.
After enabling Video passthrough, you can create a virtual machine and assign the graphics card to it to use it for video acceleration. Keep in mind that enabling Video passthrough may have some limitations and compatibility issues, so make sure to check the Proxmox documentation and your hardware specifications before enabling it.

Are you working on this request ? A few days ago there was a forum message here stating that you were doing tests, now this message is deleted. What happened?
