The compiling and runtime work well on my 4* A770 platform with SD v1.5.

Works for my B580! Thank you very much.

@leejet could you merge?

@HeyItsBATMAN It's still not working on my B580, can you share your config and OS ?

@aahouzi

OS: Arch Linux x86_64
Kernel: Linux 6.14.0-rc2
Oneapi: intel-oneapi-basekit-2025 2025.0.1.46-1

Environment:

ZES_ENABLE_SYSMAN 1
ONEAPI_DEVICE_SELECTOR level_zero:0
SYCL_PI_LEVEL_ZERO_USE_IMMEDIATE_COMMANDLISTS 1
SYCL_CACHE_PERSISTENT 1

And I source the following 3 scripts:

source /opt/intel/oneapi/setvars.sh
source /opt/intel/oneapi/pti/0.10/env/vars.sh
source /opt/intel/oneapi/umf/0.9/env/vars.sh

Thank you, i confirm i can get it to compile and run on Xe arch (alchemist i believe), integrated on Gen11 i5.
However, i get it crashing with:

@HeyItsBATMAN I see, on windows it's still not running

Hi @paoletto , I encountered the same which means OOM. You can try smaller size of image generation, e.g. -H 512 -W 512.

@Uxito-Ada thanks mate! that worked indeed! so i confirm this fix works for me as well!

@leejet Hi, could you merge this PR since it has been verified in the above comments?

this project look abandoned. I wrote this already some weeks ago. Maybe needs fork?

I don't believe it's abandonned, It's just a bit slow to update. If you take a look at the commit history, you can see that leejet comes back every month or so to merge some PR and then disappears again.

(I do have a fork with some more PRs implemented, but I don't think it should replace the original https://github.com/stduhpf/stable-diffusion.cpp/tree/bleedingedge.)

Thank you for your contribution
