There was a problem hiding this comment.
Same comment as in #15057 (review). We don't even have CI hardware to test these changes, so it's difficult to approve these.
Let's merge after you fix the editor config errors.

This PR adds SVE kernel support for the f16 (ggml_vec_dot_f16() Kernel) data type to reduce the time required for image encoding during LMM model (llava-v1.6-mistral) inference on ARM architecture.
Major code changes:
In vec.cpp file:
In vec.h file:
In simd-mappings.h:
Performance: Graviton3E
On Graviton3E with different threads, got 5-15% speedup on Image Encoding time for multimodal (LMM) inference.
Model: llava-v1.6-mistral-7b.Q4_K_M
Machine: Graviton3E
Command Used:
Perplexity
I have ran perplexity with the NEON(Original) and SVE (This PR) Implementation.
And below is the summary.
This correction does not appear to have any impact on accuracy.
