There was a problem hiding this comment.
Preferably also remove the default of GGML_PREC_Q8 from all functions to avoid accidental misuse.

Yes, it makes sense to supply it src1 prec explicitly |

…-10-10) Conflicts: - ggml-backend.cpp: upstream moved input copies to ggml_backend_sched_copy_input with host weights last (ggml-org#29943); the GGML_SCHED_BATCH_INPUTS fast path now runs in the first loop before falling back to it. - ggml-cuda/fattn-common.cuh: launch_fattn takes upstream async_kv_preload, then our parallel_blocks_fixed (GQA-6 tile launcher updated). - ggml-cuda/fattn-mma-f16.cuh: upstream swizzle refactor (ggml-org#29612); its helpers take ncols2 like the rest of the fork's config getters. - ggml-cuda/gated_delta_net.cu: keep the fork's kernel and launch geometry (its columns_per_block template argument is not upstream's cols_per_warp, ggml-org#30087). - ggml-cuda/mmq.cu: upstream per-tile src1 padding (ggml-org#29953); ggml_cuda_mul_mat_q_src1_nbytes and the MMQ input cache use the worst-case padding so producers and projections with other tiles can share the buffer. - ggml-cuda/mmq-vec-dot.cuh: fork vec_dot kernels pass GGML_PREC_Q8 to the config helpers (ggml-org#30168). - ggml-cuda/mmvf.cu/.cuh: keep both includes and the HIP declarations, upstream warp_size argument. - ggml-cuda/rope.cu: upstream grid-stride rms_norm+mul+rope (ggml-org#28175) with the fork's M-RoPE theta (nchannels instead of gridDim.y) and rope_store_cast. - ggml-cuda/top-k.cu: upstream shape-based selection (ggml-org#28713), RDNA4 tournament kept for few long rows. - src/llama-batch.*: mixed token/embd batches (ggml-org#29622) copy embd rows per entry; other batches keep pointing at the ext rows. - src/llama-context.cpp: expert copy callback also on the second MTP scheduler. - src/llama-graph.cpp: build_rs keeps the GET_ROWS of the ubatch states (GDN fusions, deferred state) and gathers the extra states from the tail like upstream's custom getter path (ggml-org#29856).
