iGPU not detected but motherboard integrated graphics working

[arnaudf9]

Hello Truenas community, I've just finished assembling a NAS server running Truenas Scale. My goal is to run multiple VMs, including one that I'd like the integrated graphics from my CPU to be passthrough to that VM.

My hardware:
- Supermicro X11SCL-F
- CORE I3-8300 3.70GHZ 8M LGA1151

When creating a VM, I can select the GPU to be passthrough to the VM. I unfortunately only see the onboard one from the motherboard (ASPEED Graphics Family), not the one from the CPU.

Things I've tried/command run to troubleshoot:
- When looking in the bios, I do not see an option to enable it. I followed this https://ahelpme.com/servers/supermicro/enable-internal-graphics-in-supermicro-servers/ and the "Graphics Configuration" option is not there.
- Tried this https://github.com/intel/intel-device-plugins-for-kubernetes/blob/main/cmd/gpu_plugin/README.md however I do end up in the error state, e.g. "0/1 nodes are available: 1 Insufficient gpu.intel.com/i915"

^ This one is the one from the motherboard. The iGPU one was not detected.

So I'm stuck. It doesn't seem the system is able to see my iGPU, nor does the BIOS? How is that possible? Is somehow the motherboard the issue?

I'm having the same issue with an i7-12700. Did you ever find a resolution?

If anyone finds themselves here in the future one of the big issues I hit was differences when a monitor was plugged in during boot.

I have a W680 i7-12700k and to get the integrated graphics working on reboots I had to either have a monitor plugged in at boot time or use an HDMI dummy plug (cheap options on Amazon).

I was getting into issues trying to run it headless, seems the integrated graphics might not be recognized unless there's an output available. Hope this helps someone!
