intel iGPU stuck at zero percent


Recommended Posts

Hello,

I am trying to setup jellyfin/plex transcoding

and this would be the first time of me using in some way the embedded gpu I got to have

now having installed GPU stats and intel gpu top the gpu seems like dead and never in use from the dashboard

(jellyfin and plex, tried both with multiple images and settings, only use software transcoding, killing my poor cpu)

Now i do not know if i am missing something or is an hardware problem

as always any hint would be really appreciated

thanks

 

 

edit: seems this family of cpus needs special config for acceleration ( here and here ), wondering if is safe to edit the i915.conf on unraid

I guess the issue is my specific CPU that only allows low power acceleration, I met other uses with same CPU on unRAID

 

Would be safe to execute this directly on unraid host (?)

cd ~/
git clone --depth=1 https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git
sudo mkdir -p /usr/lib/firmware
sudo cp -r linux-firmware/i915 /usr/lib/firmware
