Unable to get intel arc working in Debian 12 VM, device recognized, no /dev/dri entry - 33Fraise33 - 2024-04-27

Hello,
I am having a lot of issues getting an Intel ARC gpu working on Debian 12. I have enabled aspm and resizable bar in my bios.My hardware is:
- Asrock Rack X570D4U
- AMD 3700x
- 64GB Ecc Memory
- Truenas OS with Debian 12 VM with PCI Passthrough
- Intel ARC A310
My debian machine currently has the following packages installed: - jellyfin-ffmpeg5 - intel-gpu-tools - firmware-linux-free - firmware-misc-nonfree - firmware-linux-nonfree - linux-image-amd64/bookworm-backports - linux-headers-amd64/bookworm-backports - intel-opencl-icd - intel-media-va-driver-non-free
it is showing the gpu:

in dmesg when I look for the pci id in the logs I see:

Code:
$ sudo dmesg | grep -i 00:0b.0
[    0.223720] pci 0000:00:0b.0: [8086:56a6] type 00 class 0x030000

[    0.231853] pci 0000:00:0b.0: vgaarb: VGA device added: decodes=io+mem,owns=io+mem,locks=none

under /dev/dri I only see the spice virtual display:
Code:
# ls -l /dev/dri/
total 0
drwxr-xr-x 2 root root      60 Apr 27 06:33 by-path

# ls -l /dev/dri/by-path/
total 0
lrwxrwxrwx 1 root root 8 Apr 27 06:33 pci-0000:00:02.0-card -> ../card0

I enabled the module as well.
Code:
$ sudo mkdir -p /etc/modprobe.d

$ sudo sh -c "echo 'options i915 enable_guc=2' >> /etc/modprobe.d/i915.conf"

My vainfo shows the following:
Code:
$ sudo /usr/lib/jellyfin-ffmpeg/vainfo
Trying display: drm
libva info: VA-API version 1.20.0
libva info: Trying to open /usr/lib/jellyfin-ffmpeg/lib/dri/qxl_drv_video.so

libva info: Trying to open /usr/local/lib/dri/qxl_drv_video.so
libva info: va_openDriver() returns -1
vaInitialize failed with error code -1 (unknown libva error),exit

Any indicator on what I a might be doing wrong? I followed some other reddit posts and the jellyfin guidelines but to no avail.

RE: Unable to get intel arc working in Debian 12 VM, device recognized, no /dev/dri entry - Fate - 2024-04-27

I don't use Truenas. So your passthrough might not working right. Maybe your question should be redirecting at the truenas forum.

But according to the arch wiki
https://wiki.archlinux.org/title/intel_graphics
your gpu should be using guc=3

Any output on journalctl or dmesg?

I needed these packaged for VA-API on arch so your packet names may vary:
pacman -Sy libva-utils
pacman -Sy intel-media-driver
pacman -Sy intel-gpu-tools

In addition I needed those for Quicksync:
pacman -Sy intel-media-sdk
pacman -Sy onevpl-intel-gpu

You can check guc status via:
cat /sys/kernel/debug/dri/0/i915_gpu_info

Also i would recommend to add "non-free-firmware" to apt/sources
and get the "intel-microcode" package. (maybe optional)

RE: Unable to get intel arc working in Debian 12 VM, device recognized, no /dev/dri entry - TheDreadPirate - 2024-04-27

What Fate said, double check the passthrough. The TrueNAS forum would be a better place to ask. We only have LXC and LXC+Proxmox docs.

Once /dev/dri/renderD128 is visible to the VM, you shouldn't need to install anything else. jellyfin-ffmpeg bundles all the drivers needed in it.
