Is it to pass through the iGPU on Macmini6 (2012)?

[TimkaSR]

I have a Mac Mini 6 (2012) and I wonder if it's possible to pass through the iGPU

I followed this guide: https://3os.org/infrastructure/proxmox/gpu-passthrough/igpu-passthrough-to-vm/

Everything seems fine when I try to pass it through but if i try to install the intel drivers it blue screens with the error "what failed: igdkmd64.sys"

if there is any method on how to fix this please reply

Specs of the Mac Mini:
CPU: Intel i5-3210M
GPU: Intel 3rd Gen Core processor Graphics Controller
RAM: 16GB

when i go to device manager in the vm it shows two devices that i think is the igpu

Hi,

Thank you for sharing the VM config!

machine: pc-q35-7.1

Can you try to set the machine to the latest version in the VM configuration?

7.1 is the only latest one i can choose

This is a Windows VM not a Linux VM

I am also having the same problem with a mac mini 2012 and pass trough of iGPU

I tried iGPU Passthrough on two systems with PVE 8.0.x both with Error 43 in Windows Device Manager. Physical GPU passes flawlessly..

System 1:

Ryzen 7950X iGPU (not working, Error 43 and no Display Output)
Quadro K2000 (working)
RTX 4070 (working)

System 2:

Core i5 4790T iGPU (not working, Error 43 and no Display Output)

@TimkaSR probably mac mini won't let you to pass through the igpu (IIRC intel hd4x00), since the apple firmware won't give it free (no or limited IOMMU features).
It is a while ago i tried this, may be there are some new flags available for uefi boot, to make it possible.
Edit:
To add on that matter, try to install old bootcamp drivers for the gpu in your windows vm, those standard intel hd4000 drivers might not pickup the gpu because of the custom apple vbios.
that "other" pci device is not the gpu, you could share vendor id and device id of both (micsrosoft basic and other pci device), to identify the devices.

@glockmane different hardware, different issue, please open a separate thread.

Or different hardware, same issue.. I read somewhere Xanmod Kernel would work.. Will try and report..

Friend, it is not the same issue. Use search for AMD iGPU passthrough.

I have the problem with both AMD iGPU and Intel Haswell iGPU..
