PCI Passthrough Arc A380 Into VM

I recently setup a new instance of Proxmox 8.2.2 after my Intel i5 10500 died on an AMD 5700UG based system and haven't had much luck getting iGPU transcoding working (so much easier on my old Core i5) so I opted to install an ASROCK Intel Arc A380 to do hardware transcoding in a kubernetes pod running on an Ubuntu 23.10 cloud image VM. I believe I have everything configured correctly and can add the A380 devices into the test VM I spun up as PCI devices without any errors but I can't seem to get drivers to load (weren't they supposed to be native in ~> 6.5 kernels). Any help on how to proceed with getting this card working would be greatly appreciated!

Ok, so I checked my VM using lscpi -nnv and it appears that both the video and audio devices are listed. I don't see any listing for the drivers being loaded though.

After going over my configuration several times, I ended up updating the VM I was running from Ubuntu 23.10 to 24.04 LTS and suddenly the kernel drivers started working in the VM / pod! Very frustrating that I assumed the drivers were working correctly this whole time
 
Hey everyone :) first of all thanks for sharing your configs. With that I finally also got it working.
Just thought I would share some Points that I specifically had to look out for to get my Asrock A380 (the low profile Version) passed through to the VM since I was also struggling a bit:
  • As a OS Image I used the Ubuntu 24.04. LTS Server iso right away
  • Also when creating the VM I chose to stick with the Default BIOS (so for me it was SeaBIOS; UEFI wasn´t working for me before)
  • Important thing was to choose q35 Machine Type
  • Boot the VM without GPU PCI Devices passed through and run update / upgrade
  • Install qemu-guest-agent (not sure if that is needed but I installed it anyway)
  • Shutdown the VM
  • Add PCI Devices (VGA + Audio Device) and check the "PCI-Express" Checkbox
One thing is that when starting the VM at some Point the Web Console in Proxmox seems to hang (log actually shows a connection timeout error) but I could still log in over SSH and test the pass-through by installing intel-gpu-tools and then running intel_gpu_top.

Also what I noticed right after installing the GPU and booting into Proxmox that the FAN was basically pinned at 100%. And it still is even after passing it to the VM. Now the placement inside my chassis is far from ideal since right now the only possible solution for me was to use the outermost pci slot. So the Card has basically no breathing room in front of the fans. Also currently temperatures in the room itself are pretty warm as well, so not sure if it is just so warm that the fans have to spin this fast even when idling or if there is another issue.

Anyway, thanks againg :) will proceed to install jellyfin now :D

Yes, that is also what I read. Thankfully for my Setup (with a Supermicro X11DPI Mainboard) I could patch my BIOS and enable that feature with the ReBarUEFI Tool (check the wiki -> Adding ffs Module). Important to note is that I used the MMTool Method (apparently the UEFITool Method led to some non-booting Supermicro boards). Also since it took me a while to find the correct Download Link for the MMTool, here it is: link.

Also I wanted to follow up on my issue with the Fan constantly Spinning at a high rate: First thing I tried was with a fresh Ubuntu 22 VM and the Intel out-of-tree kernel modules: link but that didn´t resolve the issue. Second I tried enforcing ASPM with the help of the ASPM tuning script: link but that also didn´t get the FAN speed under control. Then I found an article from Intel regarding the issue: link. Unfortunately it is not that easy to update the firmware on Intel ARC cards under Linux (here is a guide though). Now since I wasn´t sure if I could use the OPROM from the Asrock Challenger A380 (which is the full-height version of this card, and the only one that is mentioned in the firmware compilation matrix linked in the mentioned guide) for my Low-Profile Version I decided to just go the "official" route and install the Card in a Windows Desktop and install the Intel Driver (which apparently during Driver installation also does a Firmware Update). Even though I couldn´t find any evidence that the Windows Driver install actually updated the firmware on the card it is now back in my Server and running super quiet, with a very moderate fan-speed (as I would expect) for a few hours now :)
 
How can i blacklist just my DS2? my iGPU (00:02.0) uses "i915" and "xe" also..

Your can early bind to vfio-pci 8086:56a6 (which is the ARC) and not 8086:a7a0 (which is the integrated graphics). No need to blacklist drivers. But you might want to early bind the other functions of the ARC GPU also (8086:4f92).

Like leesteken stated, edit the /etc/modprobe.d/vfio.conf file and include "options vfio-pci ids=8086:56a6,8086:4f92 disable_vga=1"
