@dsocek It seems there is a formatting error: https://github.com/huggingface/diffusers/actions/runs/17622299913/job/50216966858?pr=12310 |

What does this PR do?
The latest Gaudi stack now defaults to eager mode, where HPU/GPU Migration uses the default SDP kernel in FP32 precision. Previously, the default lazy mode used SDP in BF16 precision.
To improve performance on HPU devices, this PR changes the default to SDP with BF16 precision when running on HPU, provided that the dtype is BF16 or unset.
