* DFlash: bound intra-block draft tokens to the SWA window
The SWA mask builder applied the sliding-window distance check only to the
cross-context section; the intra-block draft-token loop masked causal-only,
so a draft token could attend to earlier block tokens beyond n_swa. Apply
the same window bound ((j - block_k) < swa_window) in both the F16 and F32
paths so it matches the cross-context section.
Behavior-neutral for dense models: the SWA mask tensor is only allocated
when the model has SWA layers (build_dflash.cpp needs_swa_mask gate), so
for dense targets the changed block is unreachable.
* DFlash: enable sliding-window attention for draft models
DFlash drafts can be trained with sliding-window attention for long context,
but the runtime ignored it: the draft loader never read the window keys and the
converter never emitted them, so SWA-trained drafts always ran full-attention.
Enable it end to end and fix the dormant SWA graph path it exposes:
- convert_hf_to_gguf.py (DFlashDraftModel): emit attention.sliding_window + an
all-layers sliding_window_pattern when the source config sets use_sliding_window.
- llama-hparams.cpp (LLM_ARCH_DFLASH_DRAFT): read sliding_window + pattern into
n_swa / swa_layers.
- build_dflash.cpp + llama-dflash.cpp: the SWA mask path had never run; an all-SWA
draft turned the full kq_mask into a dead graph node the scheduler never backs
with a buffer, then the input-set wrote it unconditionally (GGML_ASSERT buf!=NULL).
Create + set each mask only when a layer uses it; derive mask dims from whichever
mask is live. Dense/mixed drafts are byte-identical.
Validated on gemma-4-26B-A4B at long context (cross_ctx 8176 > window 2048): no
crash, no short-context regression, SWA-on recovers long-context draft acceptance.
* DFlash: derive draft SWA pattern from layer_types
The converter emitted an all-layers SWA pattern ([True]*n_layers). The z-lab
DFlash drafts are sliding-window on every layer except a final full-attention
(global) layer, so this ran that global layer as sliding-window and clipped its
long-context view. Read layer_types and emit the matching per-layer pattern
(sliding_attention -> True), falling back to all-SWA only when layer_types is
absent.

* wip: port MTP architecture
Ports the Multi-Token Prediction (MTP) architecture to the older `llama.cpp` codebase used by `ikllama`.
Changes include:
- Updating `llama_batch` to support `mtp_params`.
- Modifying `llama_decode_internal` (and `encode`) to handle MTP operations (Warmup, Update, Draft).
- Adding public APIs for MTP state management (`llama_set_draft_input_hidden_state`).
- Adapting the embedding extraction logic to skip MTP update passes.
* Refactors `server_slot` to support generic speculative decoding (MTP or Draft Model).
* core: enable hybrid outputs (logits + embeddings) for MTP support
* fix(mtp): correct KV-cache slot finding for updates
* fix(mtp): persist hidden states to prevent context corruption during drafting
* refactor(mtp): clean unused code
* fix(mtp): update server to new functions name

* Increase GGML_SCHED_MAX_SPLITS - required for larger u-batches
* Fix CPU concat in the TG case: 7.25 -> 10.5 t/s for Qwen3Next
* Fix CPU sum_rows: 10.5 -> 13.6 t/s for Qwen3Next
It was single-threaded and was taking ~25% of the computation time
during TG. It is now down to 2%.
Strangely enough, I measure 13.6 t/s with llama-bench, but if I
let the model give me an actual response with llama-cli, I get close
to 17 t/s.
* Fix CPU scale: 13.6 -> 16.7 t/s for Qwen3Next
For Qwen3Next there is a scale op on a largish tensor (548k elements)
that has a single row for TG, so was done in a single thread.
We now simply use blocks of 1024 elements.
* Optimize CPU mul: 16.7 -> 17.6 t/s for Qwen3Next
* CPU: fuse transpose -> cont -> sum_rows -> transpos: 17.6 -> 23.1 t/s for Qwen3Next
* Optimize CPU repeat: 176 -> 200 t/s for Qwen3Next PP-512
* Multithreading for OP_SUB
* Don't commit with timing trace on
* Multithread neg and sigmoid
* Be able to turn on/off fusion more easily (CPU)
* Name the mul_mat ops so we know where the time goes
* WIP
* Much better PP on CUDA
* CUDA: fuse transpose -> cont -> sum_rows -> transpose
Needs non-coontiguous variant of sum_rows.
On the CPU this gave 30+% improvement in TG performance,
on CUDA ist is disapointing 6-7%. I guess, this is because
Georgi's cont CPU implementation was so bad that skipping
it made such a big difference.
* CUDA: faster mul for special case relevant for Qwen3Next
Worth 1% in TG
* Fix CPU OP_CONT

* feat: Partial support for full templating for idefics3 in mtmd
There are still errors encoding some of the image chunks, but the token
sequence now matches transformers _almost_ perfectly, except for the double
newline before the global image which shows up as two consecutive newline
tokens instead of a single double-newline token. I think this is happening
because the blocks are tokenized separately then concatenated.
