i915-sriov-dkms VS realtek-r8152-dkms

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.

*Proper drivers if somebody needs it https://github.com/awesometic/realtek-r8152-dkms Without drivers i have very bad ping times and simply connection drop under heavy load...
