Updates dev branch with latest release (b10488) from ggml-org/llama.cpp

* Switch ROCm from 7.2.1 to 7.14

ROCm 7.14 is the first production release using TheRock build system.
It can be installed using multi-arch deliverables from wheels, debs,
rpms, tarballs or runfiles.

Adjust ROCm targets for Linux and Windows to use this instead.

* ci: switch all other Windows ROCm jobs to ROCm 7.14 wheels

Move the shared windows-setup-rocm composite action from the HIP SDK PRO
Edition installer to the multi-arch ROCm wheels (rocm[libraries,devel]).
The wheel-install logic that previously lived inline in release.yml is now
in the shared action, and both build-cache.yml and release.yml call it.

Also migrate the build-cuda-windows.yml hip job to the same wheel-based
layout (cache path/key, rocm-sdk environment setup, llvm/bin compiler
paths) so it keeps working after the action's contract changed; drop its
now-unused ROCm 7.2.1 rocWMMA download and stale include path.

* model : fix SWA not being enabled for EXAONE 4.5

load_arch_hparams tests `hparams.n_layer() == 64` before
LLM_KV_NEXTN_PREDICT_LAYERS has been read. n_layer() returns
n_layer_all - n_layer_nextn and n_layer_nextn defaults to 0, so a GGUF
carrying the MTP head (block_count=65, nextn=1) evaluates to 65 and the
whole SWA block is skipped. The model type switch further down in the
same function reads 64, because by then the key has been loaded.

n_swa is still filled in by the unconditional get_key below the block, so
llama_model_n_swa() reports 4096 and the logs look correct while only
swa_type stays LLAMA_SWA_TYPE_NONE.

This affects the official LGAI-EXAONE GGUF release as well. EXAONE 4.0 has
no MTP head, so block_count is 64 there and the check matches.

* model-loader : skip TENSOR_SKIP tensors in the metadata-only path

create_tensor asserts on a null buffer type when building from metadata
alone, but buft_for_tensor returns null by design for tensors marked
TENSOR_SKIP, which is how architectures with nextn/MTP layers mark theirs.
Those models cannot be constructed by llama_model_init_from_user at all.

The file-backed path below already returns nullptr for the same tensors, so
callers see the same thing either way.

* tests : cover exaone4 hparams ordering

Builds a synthetic exaone4 model with the layout the shipped EXAONE 4.5
GGUFs use (block_count 65 + nextn 1). The swa_type check is the one that
catches the ordering bug; the n_layer_nextn and n_layer() checks only tell
a broken fixture apart from a real regression.

Fails before the ordering fix with "swa_type is not STANDARD", passes after.

* Revert "tests : cover exaone4 hparams ordering"

This reverts commit d2f3baf.

* Revert "model-loader : skip TENSOR_SKIP tensors in the metadata-only path"

This reverts commit aecb9bc.
* test-backend-sampler: skip multi_output_sampling_chain on HIP

The new multi_output_sampling_chain test uses top_k, whose backend probs
path needs CUB (unavailable on HIP), so sampled_probs is null and the test
aborts. Add it to the existing HIP skip list alongside the other TOP_K tests.

* ci: keep gpu-rocm logs in a per-run dir keyed by GitHub run id

The self-hosted gpu-rocm runner can't upload logs to Azure blob (egress
firewalled), so a run's logs were wiped by the next run. Write each run's
logs to $OUT/run-<run_id>-<attempt>/ so an Actions run URL maps to its logs.

* test-backend-sampler: also skip multi_output_cpu on HIP

Like the other TOP_K-based subtests, multi_output_cpu's backend sampler
never initializes on HIP (no CUB TOP_K), so it aborts. Add it to the skip list.

ggml-org#26890)

This commit updates the python script that runs the original model to
generate embeddings for the causal model, to use save_output_data which
stores the token ids and the prompt in addition to logits.

The motivation for this is that the embedding logits verification will
fail as it expects these files (-prompt.txt and -tokens.bin) to exist.
With the changes in this commit the causal-verify-embeddings target
works again.
Most of the old ones have been resolved (yay) but the recent refactor of mmq paramters has caused some symbol names to change,
leaving a couple of non-ignored failures
* webui: hide loaded model in context gauge at single-model mode

* webui: keep context gauge details open state across reopens
* adapt the api

* text model ok

* working impl, need verify and clean up

* mtmd: build the pocket-tts transposed convolutions as GEMM + col2im

ggml_conv_transpose_1d has no grouped mode, so the depthwise upsample
was built as one convolution and one concat per channel, which floods
the graph with small nodes and makes kernel launches dominate the
decoder.

Fold both cases into the column form the seanet decoder already needs:
the general case reshapes the kernel to [IC, K * OC] and matmuls it
with the input, the depthwise case batches a matmul over the channels
so a step scales its own kernel. A single col2im_1d then scatter-adds
the columns back to the signal, with the same shape as before, so the
overlap-add tail, the streaming state and the bias are untouched.

Generation time per frame drops by 80% on CUDA and by 50% on CPU. The
output matches the previous implementation sample for sample, with a
correlation of 0.999994 and identical frame counts.

* flow_temp +  frames_after_eos

* chunking

* mtmd: carry the remaining pocket-tts per-pack settings

The language packs also tune the end-of-speech padding and the padding
of short prompts, next to the temperature already carried in the
mmproj: french_24l asks for 8 tail frames instead of the guessed 3,
english_2026-01 asks for short prompts to be padded with spaces.

Write both in the mmproj as clip.gen.audio.frames_after_eos and
clip.gen.audio.pad_short_text, keyed on the pack in the conversion
script like the temperature. The loader keeps them optional, so a
mmproj without them behaves as before. Map semicolons to commas for
every pack instead, the reference only asks for it on three of them and
it costs nothing elsewhere.

Existing mmproj files must be converted again to carry the two keys.

On a long french text the port now lands within 2% of the reference:
22.96s against 23.44s, with the same peak level and the same amount of
silence.

* chat : fix muse-glimmer swallowing a trailing tool call into content

Muse Glimmer routinely answers the user and calls a tool in a single
generation. The template terminates a message with <|eom|> when more
messages follow in the same turn and <|eot|> only at the end of the turn,
so the answer is closed by <|eom|> and the call opens a fresh header:

    <prose><|eom|><|start|>assistant to=<tool><|message|><atem:function_calls>...

The final-message rule read content with until("<|eot|>"), which assumed the
user-facing message is always last. There is no <|eot|> before the call, so
content ran to the end of the turn, absorbed the markup, and no tool_calls
were emitted - the tool never ran. On a tau2-bench telecom run this hit 43
turns across 19 of 114 tasks.

Stop the answer at <|eom|> and parse what follows as tool calls.

Adds models/templates/muse-glimmer.jinja and four parser tests: a plain
answer, the <|eom|> junction, markup quoted in an answer staying content,
and tool markup inside the to=self channel staying reasoning.

* vulkan: TQ2_0 (ternary) support — dequant + dedicated mul_mat_vec + matmul via dequant_funcs

First Vulkan ternary type in ggml. Correctness: OM-125m TQ2_0 vs F16 top-12
logprobs identical to 4 decimals fully offloaded (float dequant path, no Q8_K
activation quant). Speed at 125m ~= F16 (overhead-bound at this scale); the

* Adds speculative decoding support

* Make BailingMoE3 safe gate metadata optional

* bailingmoe3: apply trained SwiGLU clamps

* common: fix Bailing V3 tool argument parsing

* llama-model-saver, instantiate float vector metadata writer

* bailingmoe3: support Q-LoRA (Ling-3.0-tiny)

Ling-3.0-flash sets q_lora_rank: None and projects Q directly, so the current
implementation loads a single ATTN_Q tensor. Ling-3.0-tiny sets q_lora_rank: 256
and routes Q through a LoRA bottleneck instead:

    q_a_proj -> q_a_layernorm -> q_b_proj

Conversion therefore failed with:

    ValueError: Can not map tensor 'model.layers.3.attention.q_a_layernorm.weight'

Add the missing path, mirroring the existing deepseek2 MLA implementation:

  * constants.py       - add ATTN_Q_A / ATTN_Q_B / ATTN_Q_A_NORM to BAILINGMOE3
  * tensor_mapping.py  - map model.layers.{bid}.attention.q_{a,b}_proj and
                         q_a_layernorm
  * conversion         - emit attention.q_lora_rank when the config has it
  * bailingmoe3.cpp    - read n_lora_q; create the Q-LoRA tensors and build Q
                         through the bottleneck when q_lora_rank > 0

Everything is gated on q_lora_rank > 0. Ling-3.0-flash's config has no
q_lora_rank, the converter only emits the key when present, hparams.n_lora_q
defaults to 0, and get_key(..., required=false) leaves the target untouched when
the key is absent - so flash keeps taking the existing direct-Q branch.

The LoRA path produces the same shape as the direct projection, so the
nope/rope split, RoPE application and wk_b absorption downstream are unchanged.

* small mtp change

* bailingmoe3: support separate MTP GGUF and Q-LoRA MTP

older than 3 days from the branch tip. The check is part of

* dspark: support speculators-format checkpoints (SpecForge exports)

Speculators-format DSpark drafts (e.g. SpecForge exports for the
Gemma-4-26B-A4B target) differ from the dense DeepSpec checkpoints in
three ways:

- the config nests the backbone hparams under transformer_layer_config
  and gives the extract layers as aux_hidden_state_layer_ids
- the block is the DFlash 1+N fill-in layout: the anchor slot is a bonus
  token, not a prediction slot. Written as dflash.bonus_anchor; such
  drafts build the block and read the mask positions exactly like
  DFlash (n_max drafts from a 1+n_max block), only the Markov/confidence
  sampling comes from DSpark
- the draft output vocab may be reduced (draft_vocab_size < vocab_size)
  with a d2t remap table. The converter expands lm_head/markov_w2 back
  to the full vocab and synthesizes an lm_head bias of -1e9 on the rows
  the draft cannot produce, so the runtime needs no d2t remapping. Such
  drafts ship their own (now optional) token_embd/output tensors instead
  of sharing the target's

Verified against gemma4-26b-a4b-dspark: greedy outputs are byte-identical
with and without the draft; acceptance 0.46, mean draft len 3.7 (n_max 6).

* dspark: fold the speculators draft class into DSparkModel

One class now covers every DSpark variant. What used to pick the class is
a single flag, because the arch name turns out to be the only thing that
separates the two families: SpecForge also exports a flat schema that
carries no speculators_* fields yet still uses the 1+N bonus-anchor block,
so keying on those fields would silently mis-read its drafts.

Also rename i0 to i_first_pred in the draft read loop and the Markov head,
and give the head a real bonus_anchor bool instead of testing i0 > 0.

Converting the Qwen3-8B DeepSpec draft and both gemma-4 speculators drafts
produces byte-identical GGUFs. The one behaviour change is that the
markov_head_type check now also covers the DeepSpec checkpoints, which
previously skipped it.

* dspark: address review comments

- rename bonus_anchor to sample_from_anchor (GGUF key and code), matching
  the checkpoint config field; absent key still means anchor-first
- rework the reduced draft vocab to match EAGLE3: d2t is written as I64
  absolute target ids and the logits are scattered at runtime, instead of
  expanding lm_head/markov_w2 and synthesizing an output bias at conversion
- move the t2d skip to modify_tensors, like EAGLE3
- drop _is_specforge: the arch name only picks the sample_from_anchor
  default, embed/lm_head sharing is decided by the draft vocab size
- deduplicate the tok_embd create_tensor left behind by the rebase

Verified with the RedHat gemma-4-31b speculator draft: greedy output is
byte-identical with and without the draft; acceptance 0.26 (n_max 7).

* ci : parallelize platform builds in build-xcframework.sh

The ios-xcode release job builds 7 platform/simulator configurations
sequentially, each with -j $(nproc). Run them with at most 3 concurrent
builds (the release runner has 3 cores), splitting the cores between the
builds (-j 1 each on the runner), so total CPU pressure is unchanged while
the build phase runs about 2.3x faster.

- convert the 7 build blocks into functions (flags unchanged)
- add a run_builds_parallel pool: 3-slot sliding window, per-build logs,
  dumps the failing log and aborts on error (background job failures do
  not trigger set -e)
- queue the 2-arch builds first so the slower builds occupy the slots early

lookup instead of four hardcoded (partially commented-out) lists.

Add a "Create and push git tag" step to the release job, right before
the "Create release" step. The tag is created with git tag and pushed
with the deploy key already configured by the Clone step, instead of
relying on the Releases API (action-create-release) to create it as a
side effect.

The tag is lightweight, matching all existing b<number> release tags.
The step is idempotent: if the tag already exists (e.g. on a re-run),
creation and push are skipped.

Add INTERFACE targets for the header-only vendor libs (miniaudio, nlohmann,

are namespaced, e.g. <nlohmann/json.hpp>.

Consolidate the per-lib add_subdirectory calls into a single
add_subdirectory(vendor), keeping the cpp-httplib gate on LLAMA_BUILD_COMMON.
Consumers (llama-common, mtmd) now link the aliases instead of relying on
raw vendor/ include paths.

hash: consumers now include via "hash/hash.h"; the vendor/hash dir is kept
as a PRIVATE include so the synced upstream sources compile unmodified.
