llama: create new fused op for QSA mask ( #30640 ) llama: create new fused op for QSA scoring enroll glm5.3-next too tests : initialize the remaining tensors in test_kpool_mask The harness sentinels were left uninitialized, so leftover memory could read as NaN and fail the NaN check. ggml: generalize the k-pool mask op into ggml_top_k_mask The k-pool mask op only covered the pooled QSA selection of qwen4exp and glm5-next, while the DSA models and the DeepSeek V4 CSA build the same top-k mask by hand with fill, set_rows and add. ggml_top_k_mask(mask, top_k, score, blocks, extra) keeps the mask cells of the live picks and the extra cells, and sets the rest to -inf. Every row tensor is 4D in the layout of top_k, and the mask is broadcast to those rows, so a selection can also be made per head. score, blocks and extra are optional: without score every pick is live, without blocks a pick is a cell, and extra holds the cells a row keeps without a pick. llm_graph_context::build_fused_top_k_mask views the row tensors in the layout of kq_mask and registers the fused node. The k-pool models, the DSA attention of build_attn and the DeepSeek V4 CSA mask use it when the probe enables the op, and keep their current path on backends without it.
