[SOLVED] Proxmox LXC Jellyfin Intel QSV unable to transcode with kernel (6.8.12-5-pve)

[ern.xyz]

Recently I had updated my kernel to 6.8.12-5-pve from 6.5.13-6-pve. I had previously pinned my kernel to 6.5.13-6-pve because I was having stability issues with 6.8 initially. I was able to fix the stability issue, but I noticed my LXC container that has Jellyfin and hardware acceleration using Intel Quick Sync (QSV) broke with the kernel update. I am therefore unable to transcode using QSV. I tried pinning the kernel back to 6.5.13-6-pve, but I am still unable to transcode.

With the 6.8.12-5-pve kernel update, looking at the Jellyfin FFmepg log file, I noticed that the iGPU isn't even found:

[AVHWDeviceContext @ 0x5d4b28181280] No VA display found for any default device. Device creation failed: -22.
Failed to set value 'vaapi=va:,kernel_driver=i915,driver=iHD' for option 'init_hw_device': Invalid argument
Error parsing global options: Invalid argument

Digging deeper, looking at the LXC /dev/dri I noticed that the permissions and GID/UID for renderD128 changed and has no access.

root@Jellyfin-LXC:~# ls -l /dev/dri
total 0
crw-rw---- 1 root video 226, 0 Dec 20 15:24 card0
---------- 1 root root       0 Dec 20 16:12 renderD128

When I originally created the LXC container, I had properly passed the iGPU and made sure that my Proxmox Node had the proper configuration within the /etc/pve/lxc/<CONTAINER_ID>.conf as written in Jellyfin's guide Link

One thing I noticed on my Proxmox Node, renderD128 does not show up:

root@darkrook:~# ls -l /dev/dri
total 0
drwxr-xr-x 2 root root      60 Dec 20 10:24 by-path
crw-rw---- 1 root video 226, 0 Dec 20 10:24 card0

At this point I am at a lost. On the LXC, As a test I tried chmod -R 777 on renderD128 to see if Jellyfin would be able to utilize the iGPU, but no luck. I also tried following this solution, but until I get Jellyfin with the correct permissions for renderD128 it has not been able to work. Link.

I also tried following this thread to resolve the missing iGPU issue on my Proxmox node, but no luck here. Proxmox Thread

Specs:
Proxmox: 8.3.2
Kernel 6.8.12-5
LXC: Ubuntu 22.04.5 LTS
Jellyfin: 10.10.1

It was the simplest oversight. I have a Supermicro X11SCH-LN4F motherboard. When I updated the BIOS, it had reset my previous BIOS settings and forced the onboard graphics. I had to re-enable the iGPU passthrough at the BIOS level.

Followed these steps to resolve issue:

Happy to report that on the newer X12 series with ASPEED IPMI, you can also use the iGPU alongside the KVM when you set the following options:
- "Advanced -> Chipset Configuration -> System Agent (SA) Configuration -> Graphics -> Primary video to PCI (this selects the ASPEED iKVM GPU as primary)
- "Advanced -> Chipset Configuration -> System Agent (SA) Configuration -> Graphic -> Internal Graphics to Enabled (this force enables the iGPU on the Intel CPU)
- "Advanced -> Chipset Configuration -> System Agent (SA) Configuration -> Memory Configuration -> Max TOLUD" to "1GB" (2GB can also work, 3GB does not as it will hang in POST code 19)
