libvpl VS intel-gpu-firmware

Do all the compiling. You will need to install a lot of dependency, compilers and probably even have to build compilers if you've never done this before. Follow the respective readmes. Do Media Driver first with cmake ../media-driver -DENABLE\_PRODUCTION\_KMD=ON because of this. Then do oneVPL and oneVPL-GPU. Then FFmpeg, which has to be configured with:

Other specifics of my setup: Disabled my IGPU to weed out confounding factors. Ubuntu 22.04 with with the newest drm-tip Kernel, Intel Media Driver built from source with cmake ../media-driver -DENABLE_PRODUCTION_KMD=ON, OneVPL, OneVPL-GPU

Intel provides i915 Driver DKMS back-ports for kernel 5.15, they're specifically targeting Ubuntu but turns out they compile pretty much fine for Debian with little to no modification needed. git clone https://github.com/intel-gpu/intel-gpu-cse-backports git clone https://github.com/intel-gpu/intel-gpu-pmt-backports/ git clone https://github.com/intel-gpu/intel-gpu-i915-backports git clone https://github.com/intel-gpu/intel-gpu-firmware

## Introduction I finally got Plex Transcoding and full Intel iGPU support for 12th/13th gen Intel CPUs working on Trunas Scale 22.12.2 and Linux Kernel 5.15.*. I'm making this post to hopefully assist any other poor souls who attempt to do the same. Forgive me if this guide misses some minor details as I didn't capture my exact command history through this process. ## System Information ``` OS Version:TrueNAS-SCALE-22.12.2 Product:W680D4U-2L2T/G5 Model:13th Gen Intel(R) Core(TM) i9-13900K Memory:125 GiB ``` # Guide > Note: Here there be dragons, none of these steps are guaranteed to not break your TrueNas install and you probably won't get much in the way of assistance if you do so be careful and don't attempt this if you're not comfortable with your linux-fu. ### Re-enable APT and Install Git ``` chmod +x /usr/bin/apt* sudo apt update sudo apt install git ``` ### Clone Intel DKMS + Firmware Repo's Intel provides i915 Driver DKMS back-ports for kernel 5.15, they're specifically targeting Ubuntu but turns out they compile pretty much fine for Debian with little to no modification needed. ``` git clone https://github.com/intel-gpu/intel-gpu-cse-backports git clone https://github.com/intel-gpu/intel-gpu-pmt-backports/ git clone https://github.com/intel-gpu/intel-gpu-i915-backports git clone https://github.com/intel-gpu/intel-gpu-firmware ``` ### Build + Install DKMS modules You should refer to the GitHub repo's README.md's here with the exception that you don't actually need to install any linux-headers as they're already provided by TrueNas. If I remember correctly the same is true of most of the build-dependencies. For `OS_TYPE` assume `ubuntu_20.04` as it builds against the same kernel as we do but RTFM applies here.

Have Ubuntu 22.04 and an Arc (Other Distributions may work too idk, also 12th, 13th gen Intel) Orient yourself by following this tutorial. Do not use the Mainline Kernel use this one. For Firmware install this one additionally. Mind the altered firmware update path because of this and put the Intel Firmware here /opt/drivers-linux-firmware/i915.
