Integrate Intel Arc Support

[navjack]

I'm wondering if it would be possible to integrate this repo so the webui could get support for the Intel Arc GPUs.

So, I found another repo that works with Arc, and it seems relatively simple in terms of the current code. Of course that's using older Stable Diffusion and is limited to the standard 512x512 output. Would love to see Arc (OpenVINO) and AMD (ROCm HIP stuff I guess) integrated into this project so that a unified interface could work with any of the three. Right now, my testing of Nvidia GPUs shows them to be massively faster than AMD Navi 21 GPUs, and then based on the 512x512 performance it looks like AMD is another major leap in performance over Intel's current stuff.

Uh oh, 512x512 limitation, really? I upgraded from an 8GB AMD card to A770 because I could not create 1024x1024 due to VRAM shortage. If A770 can only make up to 512x512, then the extra VRAM is useless.

But your comment is almost half a year old. Has the situation got any better? The official A1111 still doesn't support Arc?

This actually depends on intel and pytorch, if arc is officially supported by pytorch, it is not difficult to be compatible with it.

You can manually install pytorch built for arc, and then forcefully modify the devices.device of webui to xpu, which should be sufficient for basic use.

Could you elaborate "basic use"? Does it mean something like "it would work if you only type text prompts and generate the image with the default settings, but it would crash if you try to use different settings or add modules like Lora, ControlNet (I heard of them, but I am not sure how exactly they work)"?

This is just because I'm not sure if the unofficial build and intel's implementation can fully support WebUI, this can only be known through actual testing.
