Bug Description
Describe the Bug
When trying to generate images using the SDXL-Turbo model with the sd-cpp ROCm backend, the server initializes successfully but fails during the actual image generation phase, returning a 500 error: generate_image returned no results.
Interestingly, switching to the Vulkan backend works perfectly fine with the exact same setup.
Is there a known compatibility issue with RDNA2 cards (specifically the RX 6600) and the ROCm backend in this context?
Environment
OS: CachyOS (Linux)
GPU: AMD Radeon RX 6600 (RDNA2)
System ROCm Version: 7.13.0
Model: SDXL-Turbo (sd_xl_turbo_1.0_fp16.safetensors)
Backend: sd-cpp:rocm-stable
Relevant Logs
Here is the log output from Lemonade Server showing the Auto-Tune memory allocation and the subsequent 500 error during generation:
sd_rocm.txt
Steps to Reproduce
1.Load a model like SD-Turbo
2. Type "Make a picture of a black chat"
3. See the error
