Intel Graphics (UHD 605) Passthrough - DMAR fault (Help..!)

[hige]

Hello,
I'm pretty new to proxmox and a very basic linux user

I've a NUC type box (Beelink Gemini X55) with an Intel J5005 CPU (IGD: Intel UHD 605) that came with Win10 pre-installed, but never used with Win10 because my intend was always to use it as a sort off homelab.
I'm running Proxmox VE 6.2-15 with some VMs & Containers (Home Assistant, PiHole, PHP development server, and some other things).

For my next project i would like to use this same machine as a HTPC while running Proxmox VE has host. And for that:

My goal:
Having Kodi/Plex up and running on my Proxmox server (HDMI output, HDMI sound, and hardware acceleration).
Need to be able to passthrough the integrated (and only) Intel GPU & Audio.
Desired SO: Windows10 or Ubuntu (or other: accepting suggestions )

My Hardware:
- Intel® Pentium® Silver J5005 (Gemini Lake)
- Intel® UHD Graphics 605 ( 8086:3184 )
- Beelink x55 box
BIOS American Megatrends Inc / VT-x & VT-d Enabled
Note:
- GPU NOT UEFI compatible ( i suppose)
- GPU NOT Intel GVT-g compatible ( i suppose)

What i've done:
I've installed Proxmox (alone) & followed the official guide (https://pve.proxmox.com/wiki/Pci_passthrough) and many other solutions proposed around the net.
I've tried pretty much every combination possible i've found around while googling for solutions.
Best results achieved:
- Ubuntu 20.04LTS fully working but a lot of DMAR fault errors and some hangs and after some time it crashes and freezes and i need to reset VM
- Windows 10 recognizing IGD but with codec error 43 while RDP (no HDMI output)
Both with Seabios.

Actual Settings:
GRUB:

I'll post any other info if needed.
Thanks in advance for your time.

Anybody succeeded so far?

I'm also trying a similar VM + Kodi like setup with my NUC type box (GA-J3455N-D3H / HD 400), but I'm failing with a similar error:

[Dunuin]

Did you tested if that CPU can handle HTPC workloads?
I switched some weeks ago from my bare metal installed J3710 (quadcore 2.64GHz), 8GB RAM, Intel HD Graphics 405 with Win10 to a HTPC-VM on my big server, because even watching 1080p youtube videos used 100% CPU utilization on all 4 max clocked cores.

I think you wouldn't have fun watch media with that especially if it is additionally virtualized so you got virtualization overhead too.

 

[nieebel]

I'm currently using Kodi/LibreELEC on a Udoo Dual 1GHz i.MX6 ARM Cortex-A9 CPU... which works pretty decent for this quite old hardware. Unfortunately, with LibreELEC 8 (Kodi 17) not all Apps are working anymore hence I'm checking for some alternatives. But yes, the J3455 might not be the optimal alternative.

 

[tristank]

The J3455 or for that matter the Apollo Lake / Goldmont plus / Gemini Lake platforms are not supported for gvt-g-linux. See here, here, here and here.
