Phoronix: Intel Xe Kernel GPU Driver Starts Landing SR-IOV Bits & Other Features For Linux 6.9

Upstreamed for Linux 6.8 is the experimental Xe kernel graphics driver that is a modern replacement to the "i915" Direct Rendering Manager driver. The Xe kernel driver targets Tigerlake graphics and newer while it won't be until Lunar Lake / Xe2 when it aims to become the default driver for Intel iGPU/dGPU graphics. For the upcoming Linux 6.9 kernel merge window are more feature changes and fixes to this new open-source Intel kernel graphics driver...

really hope sr-iov will support consumer cards, it's not a high hope, im not expecting it. but I do wish it

I would buy one immediately if that were the case.

Intel iGPUs on some recent gen CPUs have SR-IOV support. For the discrete cards, just like AMD and NVIDIA, market segmentation is still being applied (i.e. only the datacenter card's firmware announce the capability). I do not recall anyone suggesting the next gen consumer Battlemage GPU's are going to support SR-IOV, but one can certainly wish.

They do have support in hardware but no software utilizes it. On Windows WSL-g and Windows Sandbox use it, or any HyperV VM if you fiddle enough with it. On Linux side it does not work at all. I've been waiting for this since I bought my laptop. On my old laptop, GVT-g worked. On this one, nothing works.

wslg, Hyper-v on PC/Workstation windows versions and windows sandbox do not use SR-IOV, they utilize driver passthrough, it's more analogous to virtio-native-context.

On windows server im not sure, but it would probably fall under DDA

I remember that before the currently available Intel Alchemist GPUs were released a presentation had mentioned that they would have SR-IOV, it just failed to specify that it wouldn't be usable on all GPUs of the family. To this day my ears perk up every time I see mention of SR-IOV for Intel GPUs. If it ever becomes usable on consumer discrete GPUs I'll definitely be very interested too.
