PCIe pass through odd problem.

[Blaster]

Hello,

Looking for some input. Why would a system allow a gpu pass through (Nvidia 3060) to plex. But not the igpu (following the similar steps with blacklisting i915 etc… of note I was able to pass through an igpu on a different system.

The system that I’m having issues with is a i13900 with UHD 770 on an Asus z790 proart creator wifi(lastest bios). I’m able to pass a 3060 from this system with no issues.

The system I was able to get working with igpu is a i13500 with the same UHD 770 alder lake gt1. Different motherboard however a gigabyte z790 aorus elite x wifi.

Any input would be greatly appreciated.

Of note I was able to cluster three systems together and use resource mapping to allow plex HA failover. Probably not the intended use of proxmox haha…but itworks pretty good in testing.

Integrated graphics is often much more complicated as it shares memory (and possibly other channels) with the CPU. Sometimes the drivers for the integrated graphics assume that it's directly connected to the CPU or won't even load because they don't see the integrated graphics in the PCIe layout where they expect it. And PCI(e) passthrough is always trial and error, unfortunately. Maybe pass the integrated graphics to a container instead? I have no concrete suggestions for your specific setup, sorry.

I’ll give an LXC a go and see what happens.

Thanks.
