i915-sriov-dkms VS intel-gpu-i915-backports

The i915 driver doesn't have SR-IOV mainlined just yet, so you need to build a dkms module to get it going.

Then I tried the SR-IOV approach, installed the latest proxmox kernel which had this module already patched in and followed the instructions on the page but lspci | grep VGA reports 00:02.0 VGA compatible controller: Intel Corporation Alder Lake-UP3 GT1 [UHD Graphics] (rev 0c) as before. This is the output of dmesg | grep i915:

For specifics: Up until last month, for gpu passthrough in Proxmox you have to use this random driver : https://github.com/strongtz/i915-sriov-dkms/tree/master With new Proxmox 8, it should have worked, but I still had to install this driver to even begin working on passthrough. Now I passed it to a UbuntuVM. Now Ubuntu by default doesn't support Alder lake iGPU completely. I installed kernel 6 somthing and the previous mentioned github driver. Now guess what, Plex doesn't support this GPU. This is the thread where I finally stopped. https://forums.plex.tv/t/movie-corruption-when-plex-decodes-4k-hdr/834529/45

There’s actually 2, theres the intel lts one, which i guess they did do something it just never amounted to anything, explained here:

DKMS module from /u/strongtz github

SR-IOV does allow sharing the iGPU between a host and a guest but mainline linux doesn't support it yet. Intel is planning to mainline it later this year though and there's this dkms module if you know what you're doing and wanna try it.

dnf install -y @development-tools git dkms git clone https://github.com/strongtz/i915-sriov-dkms

Hello, everyone! I've been trying to pass through my dedicated graphics card on my optimus XPS 15 9510 for... quite a while. I was advised by [this blog post](https://lantian.pub/en/article/modify-computer/laptop-intel-nvidia-optimus-passthrough.lantian) that I need to pass through both my integrated graphics card and the dedicated graphics card in order to use the dedicated graphics card on the host, by my 11th Gen Intel i7-11800H doesn't support GVT-g, only SR-IOV. So, I installed [this kernel module](https://github.com/strongtz/i915-sriov-dkms) which allowed me to seemingly successfully create a VF and pass it through alongside my dedicated graphics card.

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.

I would try a kernel that has all of Intels gpu patches available: https://github.com/intel-gpu/intel-gpu-i915-backports
