CUDA: Limit DeviceSegmentedSort to immediate mode (#21718)
* CUDA: Limit DeviceSegmentedSort to immediate mode

DeviceSegmentedSort is currently not capturable in a cuda graph. Hence,
we have to go for the slower DeviceSegmentedRadixSort in that case.

invoke ggml_backend_compare_graph_backend twice to enforce each test to
run in graph mode

* webui: add setting for first-line chat titles

Add an opt-in setting (`titleGenerationUseFirstLine`) to use the first
non-empty line of a prompt as the generated conversation title.

Previously, the complete multi-line prompt was being used, which created
long titles for complex queries. Coupled with
"Ask for confirmation before changing conversation title", the dialog
would overflow.

mtmd: add Gemma 4 audio conformer encoder support (#21421)
* mtmd: add Gemma 4 audio conformer encoder support

Add audio processing for Gemma 4 E2B/E4B via a USM-style Conformer.

Architecture:
- 12-layer Conformer: FFN → Self-Attention → Causal Conv1D → FFN → Norm
- Subsampling Conv Projection: 2x Conv2D(stride=2) with LayerNorm
- Full self-attention with sinusoidal RPE and sliding window mask (24)
- Logit softcapping at 50.0, ClippableLinear clamping
- Output: 1024 → 1536 → RMSNorm → multimodal embedder

Mel preprocessing (dedicated mtmd_audio_preprocessor_gemma4a):
- HTK mel scale, 128 bins, magnitude STFT, mel_floor=1e-3
- Standard periodic Hann window (320 samples), zero-padded to FFT size
- Semicausal left-padding (frame_length/2 samples)
- Frame count matched to PyTorch (unfold formula)
- No pre-emphasis, no Whisper-style normalization
- Mel cosine similarity vs PyTorch: 0.9998

Key fixes:
- Tensor loading dedup: prevent get_tensor() from creating duplicate
  entries in ctx_data. Fixed with std::set guard.
- ClippableLinear clamp_info loading moved after per-layer tensors.
- Sliding window mask (24 positions) matching PyTorch context_size.
- Skip Whisper normalization for Gemma4 mel output.

Tested on E2B and E4B with CPU and Vulkan backends.
Transcribes: "Glad to see things are going well and business is starting
to pick up" (matching ground truth).

mtmd : add MERaLiON-2 multimodal audio support (#21756)
* mtmd : add MERaLiON-2 multimodal audio support

Adds support for A*STAR's MERaLiON-2 audio-language model (3B and 10B)
to the multimodal framework.

Architecture:
- Whisper large-v2 encoder for audio feature extraction
- Gated MLP adaptor: ln_speech -> frame stack (x15) -> Linear+SiLU -> GLU -> out_proj
- Gemma2 3B / 27B decoder

The mmproj GGUF is generated via convert_hf_to_gguf.py --mmproj on the full
MERaLiON-2 model directory (architecture: MERaLiON2ForConditionalGeneration).
The decoder is converted separately as a standard Gemma2 model after stripping
the text_decoder. weight prefix.

New projector type: PROJECTOR_TYPE_MERALION

Supports tasks: speech transcription (EN/ZH/MS/TA), translation, spoken QA.

hexagon: improved Op queuing, buffer and cache management (#21705)
* hexagon: introduce op request batching and rewrite buffer managment

The host now prepares batches of requests and dispatches them via a single dspqueue message.

Buffers are mapped explicitly by NPU while processing batches.

* hex-dma: disable l2 bypass since to work around new issue due to no flushes between Ops

* hex-utils: add explicit l2flush and l2clear helpers

* hex-opreq: use fine-grain per tensor l2 management

* hex-opreq: avoid redundant invalidates for tensors we already flushed

* hex-opreq: update debug messages

* htp-opreq: reuse ops_context

* hex-opreq: do not flush or invalidate cache lines beyond buffer boundry

* hex-opreq: fix errors in log message

* Revert "hex-opreq: do not flush or invalidate cache lines beyond buffer boundry"

This reverts commit 8b7f0a55a750a6430ce4eb1874c7feb3d720056d.

* hexagon: limit l2 flushes to 1MB which covers l2 cache

* hex-opreq: limit cache flush to 4MB

Looks like 4MB cont. vitual space should cover the 1MB cache.

* hexagon: drop cache flush size to 2MB

* hex-opreq: start reworking opreq packing

* hex-opreq: introduce new way of packing opbatch where tensors are stored separately

* hex-opreq: add a simple fastrpc call to force unmap all buffers

* hex-l2flush: somehow 2MB does not seem robust, also cleanup step size to use line-size

* hex-opreq: bump opreq batch size to 256

* hex-mm: place src1 spad at the top of vtcm for easy reuse

* hex-ops: introduce internal types and disable src1 reuse for now

Nothing new just formalizing the repack / qyn.quant types we've been using.

* htp-opreq: use tensor pointers instead of copies

* hex-opreq: introduce more robust way for tracking vtcm/spad reuse

This removes the SKIP_QUANTIZE flag that became fragile with the addition of HMX and other ops.

* hex-cumsum: fix error post opreq merge

* hex-opreq: move request batch handling into the session

Prepping everything for using dspqueue buffers and doing that inside the session is much cleaner.

* hex-mm: yet another fix for src1 reuse when we're mixing hmx/hvx

* hex-bufs: introduce pinned mmapings and use non-pinned ones for model buffers

* hex-buf: add support for allocating shared/pinned buffer for opreqs

* hex-opbatch: make opbatches configurable

* hex-naming: better name for ggml_hexagon_shared_buffer

* hex-naming: add session->c_name() helper

* hex-opbatch: start using shm but still copy for now

* hex-opbatch: use shared buffer for packing opbatch

* hex-opbatch: beter naming for opbatch related classes and code

* hex-opbatch: reuse batched tensors with same data/dims/strides

* hex-opbatch: update logging

* hex-opbatch: add support for vmem limit for op batching

* hex-opbatch: update htp side to properly support dynamic mmap/unmap

* hex-opbatch: add OB and OQ params for run-completion script and fix the asserts in batch processing

* hex-opbatch: fixed src1 handling in act ops

* hex-act: fix empty src1 handling in swiglu and friends

Simplify preamble macro while at it

* hex-mm: minor fix vtcm and dma handling in matmul

cleaning up some left-overs from merges

* hex-opbatch: allocate extra 1KB for dspqueue overhead

* hexagon: fix softmax for non-aligned tensors and cleanup vtcm alloc

* hex-mm: properly handle hmx_disabled flag

* hex-ops: update comments

* hex-ops: add debug output for get/set-rows

* hex-mmap: optimize un/mapping of buffers

* hex-opreq: global cache flush and invalidate beyond 128KB threshold

* hex-ops: add super simple opfilter regex for debugging

If an Op matches the regex hex backend will reject it.

* hex-opbatch: wireup newer ops missed in merge and update main switch to detect this in future

* hexagon: improved vtcm acquision to remove inter-op overhead

Fully compatible with QNN-HTP coex

* hex-mm: fixed hvx fallback path

* hex-mm: lower the vmem threshold a bit further to ~3GB

* hexagon: update debug & error logs

This also fixes an issue with newer llvm merging repack and non-repack
functions. We use those pointer to distinguish between buffer types.

* hexagon: move ops context into main context

Just a cleanup. We don't need separate contexts at this point.

* hex-opbatch: cleanup naming and headers for opbatch and related descriptors

* hex-fa: it's now better to enable FA during TG to reduce graph splits

* hexagon: remove GGML_HEXAGON_EXPERIMENTAL env var

It's no longer useful. Please use more flexible GGML_HEXAGON_OPFILTER to disable Ops
if needed for debugging or validation.

* hexagon: fixed editorconfig check

* Update ggml/src/ggml-hexagon/ggml-hexagon.cpp

server : ignore --alias when using --models-preset (#21380)
I'm not sure what the purpose of keeping `--alias` was when using
`--models-preset`, but the result is really weird, as shown in the
following logs:

    $ build/bin/llama-server --models-preset preset.ini --alias "Gemma 4 E4B UD Q8_K_XL"
    ...
    init: using 31 threads for HTTP server
    srv   load_models: Loaded 2 cached model presets
    srv   load_models: Loaded 1 custom model presets from preset.ini
    main: failed to initialize router models: alias 'Gemma 4 E4B UD Q8_K_XL' for model 'angt/test-split-model-stories260K:F32' conflicts with existing model name

So I propose to simply ignore `--alias` too in this case. With this
commit, the server starts in routing mode correctly.

HIP: add CDNA4 (gfx950) architecture support for MI350X/MI355X (#21570)
Add AMD Instinct MI350X/MI355X (gfx950, CDNA4) support:

- vendors/hip.h: Add CDNA4 preprocessor define for __gfx950__
- common.cuh: Add GGML_CUDA_CC_CDNA4 and GGML_CUDA_CC_IS_CDNA4 macros
- mma.cuh: Route CDNA4 to compatible MFMA instructions:
  * f32 matmul: mfma_f32_16x16x4f32 (xf32 variant unavailable on gfx950)
  * bf16 matmul: mfma_f32_16x16x16bf16_1k (same as CDNA3)
  * int8 matmul: mfma_i32_16x16x32_i8/32x32x16 (same as CDNA3)
- mmq.cuh: Include CDNA4 in stream-k kernel dispatch

CDNA4 is largely compatible with CDNA3 except:
- No xf32 MFMA (mfma_f32_16x16x8_xf32) — routes to f32 path
- Different FP8 format (e4m3fn vs e4m3_fnuz) — not changed here

Tested on AMD Instinct MI355X (gfx950), ROCm 7.0.1:
- Build: compiles cleanly with -DAMDGPU_TARGETS=gfx950
- llama-bench (Qwen2.5-1.5B Q4_K_M, single GPU):
  * f16+FA: 40,013 tok/s prefill, 254 tok/s decode
  * q8_0+FA: functional
- Flash attention: works correctly
- MMQ: works correctly with stream-k dispatch

ggml: backend-agnostic tensor parallelism (experimental) (#19378)
* ggml: backend-agnostic tensor parallelism

* support for GPT-OSS, Qwen 3 MoE

* partial Vulkan fix

* add support for 4/8 GPUs

* unconditional peer access

* re-use buffers + ggml contexts

* fix output pattern

* NCCL support

* GGML: HIP: add RCCL support

* Remove shfl and AllReduce from backend interface

* move allocation workaround out of ggml-alloc.c

* 2d tensor set/get support

* Fix the seg fault without NCCL

* Apply suggestion from JohannesGaessler

* support for tensor dims % n_devs != 0

* fix view_offs scaling

* arbitrary num. of GPUs/tensor split

* fix compilation

* better granularity estimate

* Support device-specific host buffer types if all underlying backends expose the same type. This allows using pinned memory instead of pageable memory for CUDA.

Fix compilation errors.

* partial Qwen 3 Next support

* Fix qwen3 30b (#8)

* Fix crash with Qwen-30B-A3B Q4_0

Qwen-30B-A3B Q4_0 has an intermediate dimension of 768. Using a granularity of 256 forces an uneven split between GPUs, which is not supported by the current implementation.

* Decide block size based on tensor quantization type

* Fix crashes due to KV cache serialization (#9)

KV cache serialization requires non-zero offsets on the tensor. Add support in the meta backend to set/get a tensor with a non-zero offset.

* metal : fix build (#7)

* static memory allocations, fix usage count

* fix tensor granularity

* more even memory distribution

* use BF16 for allreduce

* rebase fixup

* better error message for unsupported architectures

* Fix device mismatch during scatter of allReduce. (#11)

There is a mismatch between the dst buffer device and the backend device, causing the use of sync copies

* Enable the previous allreduce implementation. It is better in both perf and stability (#12)

* delay AllReduce for Moe for less I/O

* build : clean-up compile warnings

* backend : move most of the meta backend API to ggml-backend-impl.h

* cont : hide unused public API in the implementation

* llama : use llama_device + remove ggml_backend_dev_is_meta()

* ggml-backend : remove unused alloc include

* minor : remove regex include

* ggml : introduce ggml-ext.h for staging new APIs

* rebase fixup

* fix tests

* llama : more robust logic for determining Meta devices (#16)

* llama : more robust logic for determining Meta devices

* cont : fix devs size check
