225088ea76 sycl: Improve mul_mat_id memory efficiency and add BF16 fast path (#22119)
* sycl: size mul_mat_id staging buffers by routed rows

Previously src1_contiguous/dst_contiguous in ggml_sycl_mul_mat_id were
sized to ggml_nelements(src1/dst), which over-allocates when ne12 > 1
and can fail with UR_RESULT_ERROR_OUT_OF_HOST_MEMORY on Level Zero for
MoE models (notably with --cpu-moe). Size them by the actual number of
routed rows (ids->ne[1] * n_ids) instead.

* sycl: add bf16 mul_mat fast path via DNNL

When src0 is BF16 (commonly the case for lm_head / output.weight), the
existing f16 path is skipped because bf16 isn't covered, and the f32
fallback dequantizes the entire src0 slab to f32 in a single pool alloc
(row_diff*ne00 floats). For large-vocab models this can reach several
GB and fail with UR_RESULT_ERROR_OUT_OF_HOST_MEMORY on Level Zero.

Add a bf16xbf16 -> f32 DNNL matmul fast path that uses the bf16 storage
in place and only materializes a small src1 bf16 conversion buffer. bf16
matmul accumulates in f32, so it's correct even when the op requests
GGML_PREC_F32 (as lm_head does).

- gemm.hpp: map bfloat16 to dnnl::memory::data_type::bf16.
- convert.{hpp,cpp}: expose ggml_get_to_bf16_sycl for f32/f16/bf16 -> bf16.
- ggml-sycl.cpp: take the bf16 path early in ggml_sycl_op_mul_mat_sycl
  when DNNL and GGML_SYCL_HAS_BF16 are both available.

7bfe60fdf9 mtmd, llama : Update HunyuanVL vision-language model support (#22037)
* mtmd, llama : add HunyuanVL vision-language model support

- add LLM_ARCH_HUNYUAN_VL with M-RoPE (XD-RoPE) support
- add PROJECTOR_TYPE_HUNYUANVL with PatchMerger vision encoder
- add HunyuanVL-specific M-RoPE position encoding for image tokens
- add GGUF conversion for HunyuanVL vision and text models
- add smoke test in tools/mtmd/tests.sh

* fix: fix HunyuanVL XD-RoPE h/w section order

* fix: Remove redundant code

750579ff14 common: Refactoring sampler parameters (#20429) (#22233)
This change refactors the reasoning_budget_message parameter from the
common params into the sampling parameters specifically. It also removes
the reasoning_budget common parameter and standardizes on the existing
reasoning_budget_tokens parameter in the sampling configuration.

98d2d2884e mtmd: Add support for Reka Edge 2603 (#21616)
* feat: (vocab) fix stray text appended in llama_decode_text

Remove accidental concatenation of the full `text` string when
formatting UNK_BYTE hex escapes. Only the closing "]" should be appended.

* feat(mtmd): add Yasa2 vision encoder support

Add a Yasa2 (ConvNeXtV2-based) vision encoder for reka-edge:
- Register PROJECTOR_TYPE_YASA2 and tensor name definitions
- Add yasa2_block/yasa2_stage model structs
- Implement graph builder with ConvNeXt stages, GRN, adaptive pooling
- Wire into clip.cpp switch statements and mtmd.cpp init_vision
- Use mtmd_image_preprocessor_fixed_size for image preprocessing

* feat(chat): add reka-edge template handler (tools, thinking)

- Add chat-reka.cpp/h implementing PEG-based parser for reka-edge format
- Add Reka-Edge.jinja chat template
- Detect reka-edge template in try_specialized_template()
- Add LLAMA_EXAMPLE_MTMD to chat-template-file arg

* feat: add reka vlm to gguf conversion script

Converts Reka Yasa2 hf checkpoints to GGUF format:
- Text decoder: Llama-arch with tiktoken/BPE vocab
- Mmproj (--mmproj): ConvNeXt vision backbone + language_projection
- Generates 2D sincos positional embeddings for vision encoder

* test: add Reka Edge chat template and parser tests

- test-chat-template: oracle tests comparing Jinja engine output vs
  common_chat_templates_apply for text, tools, thinking, images, video
- test-chat: PEG parser tests for Reka Edge format, round-trip tests
  for image/video content parts, common path integration tests

* scripts: add Reka Edge mixed quantization helper

Q4_0 base quantization with Q8_0 override for the last 8 transformer
blocks (layers 24-31) via --tensor-type regex.

* fix: adapt chat-reka and tests to upstream API

- Use autoparser::generation_params (not templates_params)
- Add p.prefix(generation_prompt) to PEG parser
- Simplify reasoning parser to match LFM2 pattern
- Remove image/video oracle tests (unsupported by oaicompat parser;
  no other multimodal models test this path)

* fix: avoid duplicate tensor loading in yasa2 vision encoder

TN_YASA_PATCH_W and TN_PATCH_EMBD both resolve to "v.patch_embd.weight",
causing the same tensor to be loaded twice into ctx_data and overflowing
the memory pool. Reuse the tensors already loaded by the common section.

* chore: update image pre-processing settings

The reka-edge model depends on the following settings in an older
fork of llama.cpp:
1. Fixed square resize
2. BICUBIC
3. add_padding=false

In current llama.cpp, this means setting:
- image_resize_algo = RESIZE_ALGO_BICUBIC
- image_resize_pad = false

* chore: remove reka gguf conversion script

* chore: remove reka quantization script

* chore: remove unnecessary changes from PR scope

This commit removes a couple of unnecessary changes for the PR scope:
1. BPE decoder bug fix - this affects reka edge because there's a bug
in our tokenization that doesn't represent <think> tokens as special
tokens. However this isn't meant to be a thinking model so when run
with --reasoning off the edge case does not affect us

2. --chat-template-file support from llama-mtmd-cli - the focus is on
llama-server and the reka edge gguf contains the necessary metadata
to detect the chat template

3. reka edge oracle test cases - no other model has similar test cases,
so I removed it for standardization

* chore: remove unnecessary ggml_cast

This commit removes unnecessary ggml_cast after updating the
reka vlm -> gguf conversion script on hugging face.

* chore: remove redundant code

* chore: remove unnecessary ggml_cont calls

This commit removes all ggml_cont calls except the four that
precede ggml_reshape_3d/ggml_reshape_4d. Those are necessary
because ggml_reshape recomputes strides assuming contiguous
layout and asserts ggml_is_contiguous.

Other operations (ggml_mean, ggml_add, ggml_mul etc.) use
stride-based indexing and handle non-contiguous inputs
correctly and so we are ok to remove ggml_cont for those.

* chore: remove unnecessary ggml_repeat calls

This commit removes unnecessary ggml_repeat calls because the underlying
ops already broadcast automatically.

Every ggml_repeat in yasa2.cpp was expanding a smaller tensor to match
a larger one's shape before passing both to an elementwise op (ggml_add,
ggml_sub, ggml_mul, or ggml_div). This is unnecessary because all four
of these ops already support broadcasting internally.

* chore: restore ggml_cont needed for cpu operations

* refactor: locate reka chat template handler in chat.cpp

* chore: remove unnecessary warmup tokens

* chore: add code comments on image_resize_pad

* chore: remove custom reka parsing code

* chore: revert common/chat.cpp

* Uncomment debug logging for PEG input parsing

788fcbc5dd [SYCL] Fix reorder MMVQ assert on unaligned vocab sizes (#22035)
* [SYCL] Fix reorder MMVQ assert on unaligned vocab sizes

The reorder mul_mat_vec_q dispatchers for Q4_0, Q8_0, Q4_K, and Q6_K
asserted that block_num_y was a multiple of 16 subgroups. Models with
a vocab size not divisible by 16 (for example HY-MT at 120818) aborted
on model load when the output projection tripped the assert.

I replaced the assert with padding: block_num_y now rounds up to a
whole number of subgroup-sized workgroups. The kernel already has the
row bounds check (`if (row >= nrows) return;`) so the extra padded
threads early-exit cleanly. Row values are uniform across a subgroup
so the collective reduce stays safe.

For aligned vocab sizes the padded block_num_y equals the old value,
so the kernel launch is identical and there is no regression.

Thanks to @arthw for flagging the relationship to #21527.

Fixes #22020.

AI assisted coding, tested on Intel B70 hardware.

* sycl: use WARP_SIZE for num_subgroups in reorder MMVQ launches

Replaces the hardcoded 16 with WARP_SIZE in the four reorder_mul_mat_vec
launch helpers (Q4_0, Q8_0, Q4_K, Q6_K). Compile-time no-op on the Intel
target where WARP_SIZE is 16, but makes the relationship to subgroup
size explicit. Per review by @NeoZhangJianyu on #22035.

09b4efa95f cmake: remove CMP0194 policy to restore MSVC builds (#21934)
#21630 added the CMP0194 NEW policy to silence a CMake warning, but on Windows runners it caused CMake to prefer the MinGW toolchain for ASM and broke MSVC builds.

Reverting only that policy block restores the previous working behavior. The CMake 4.1+ warning comes back, but that is cosmetic and does not break any platform.
