SYCL Intel UHD 770 segfault

Hi, trying to use SYCL on the 12600K's iGPU UHD 770, I've ran into the following issue:

(despite-dependencies because of blender)

and

wget https://archlinux.thaller.ws/extra/os/x86_64/intel-oneapi-basekit-2024.1.0.596-3-x86_64.pkg.tar.zst
sudo pacman -U intel-oneapi-basekit-2024.1.0.596-3-x86_64.pkg.tar.zst

from https://archlinux.org/packages/extra/x86_64/intel-oneapi-basekit/ instead of a simple pacman -S --needed intel-oneapi-basekit as the current repo package appears broken.

Then installing dnn and the driver with sudo pacman -S --needed onednn onetbb intel-compute-runtime.

I've built it like this:

. /opt/intel/oneapi/setvars.sh
cmake .. -DSD_SYCL=ON -DCMAKE_C_COMPILER=icx -DCMAKE_CXX_COMPILER=icpx -DGGML_SYCL_F16=OFF
cmake --build . --config Release

F16 on or off makes no difference, the same result:

I can see the iGPU being used at 100% for render/3D by sd executable, visible in intel_gpu_top of intel-gpu-tools package on the line

[DEBUG] ggml_extend.hpp:1001 - flux compute buffer size: 398.50 MB(VRAM)

for approx. 20 seconds, then it proceeds to

[Green-Sky]

Could you run it inside gdb and give us the stacktrace?

gdb --args stable-diffusion.cpp/build/bin/sd --diffusion-model  stable-diffusion.cpp/models/flux1-schnell-q8_0.gguf --vae stable-diffusion.cpp/models/ae.safetensors --clip_l stable-diffusion.cpp/models/clip_l.safetensors --t5xxl stable-diffusion.cpp/models/t5xxl_fp16.safetensors --steps 4 -p "a lovely cat" --cfg-scale 1.0 --sampling-method euler -v

and hit r+enter.

[Green-Sky]

You might also try pulling a more up-to-date ggml. There are always advancements and fixes happening upstream.

stable-diffusion.cpp was cloned with --recursive, head of ggml was detached at 21d3a30 (11 days) despite fresh git pull on stable-diffusion.cpp, after

cd ggml
git pull origin master

it was fast-forwarded to the current fbac47b

This resulted in build errors due to disabled GGML_MAX_N_THREADS of ggml c584042 in include/ggml.h. Moving the #define GGML_MAX_N_THREADS 512 outside the #ifndef GGML_MAX_NAME let me build again.

I guess sd.cpp's type list is out of date, bc that is very wrong. Would also explain the typesize tensor mismatch assert.

[Green-Sky]

Yea, updating ggml might be more work than I thought.

Instead, can you try applying some patches manually, and see what happens? Like this one: https://github.com/ggerganov/llama.cpp/pull/9346

[Green-Sky]

It would also help if you could build in Debug mode, so we have line numbers :)

[recallmenot]

so after

cd ggml
git checkout 21d3a30

I applied llama.cpp 2a358fb.

and rebuilt with debugging.
