* ci : update the oneAPI toolkit to 2026.1
oneDNN is removed from Intel Deep Learning Essentials in 2026.0, so
staying on the deep-learning-essentials path would silently lose oneDNN
support when the toolkit version is updated. Switch both the Ubuntu and
Windows CI jobs to the new unified Intel oneAPI Toolkit installer,
which still includes oneDNN (until 2027.0) and keeps the component IDs
unchanged for the Windows install script.
Measured with the same code (b10899) built with oneAPI 2026.1 vs the
2025.3-based release build on Arc B570: prompt processing 1331 vs 434
t/s (3.1x), token generation 50.1 vs 45.3-48.0 t/s.

* server : support multimodal input for /v1/embeddings (Qwen3-VL-Embedding)
Accept the OpenAI-style wrapped content array format for multimodal
embedding requests. Each {"content": [...]} object is one input that
produces one embedding; text parts are concatenated and image_url parts
are decoded via handle_media then spliced with process_mtmd_prompt.
The legacy formats (plain string, token arrays, mixed arrays, and the
{prompt_string, multimodal_data} object) continue to work unchanged via
tokenize_input_prompts. Bare content arrays (the unwrapped shape) are
rejected with a migration message.
Also disables KV prefix reuse for stateless embedding/rerank tasks so
that repeated inputs do not incorrectly share cached KV across requests.

* models: pad on the left with ggml_pad_ext
The Parakeet, LFM2-Audio, Granite Speech and Gemma 4 audio encoders
build a left padding as a right pad followed by a roll, and DFlash2
concatenates a zero filled block in front of the previous tokens.
ggml_pad_ext does both in one node now that every backend supports a
left padding. The Gemma 4 audio embeddings are bit identical.
* models: skip the DFlash2 taps that only read padding
A tap at or past block_size shifts every row out of the block, so its

* cont : fix typo
* metal : allow fusing 0-element nodes to keep graph packing shape-independent
The fusion packing in ggml_metal_fusion_max excluded 0-element tensors and
the topk_moe/moe_reduce checks rejected n_tokens == 0, so graphs decoding
batches with no outputs packed differently from the worst-case reserved
graph. The Metal optimizer then reordered the nodes differently and
ggml_gallocr_needs_realloc failed on the layout mismatch, forcing an
unexpected graph re-reserve (caught by GGML_SCHED_DEBUG_REALLOC).
Treat empty tensors like their non-empty counterparts: match them in the
pattern sequence and only reject genuinely malformed shapes. Fused kernels
dispatch zero threadgroups for empty graphs, which is a legal no-op.

* tests : run test_multi_seq_split_replay as a separate test
test_multi_seq_split_replay was invoked at the end of test_rollback,
so its result was folded into the rollback status and it only ran when
the rollback part passed.
Give it its own test_status return, run both tests independently over
both cache fills via a shared run_tests helper, and report them as
separate rollback / split replay columns in the --models table with
per-test summaries. The exit code fails when either test fails.

--model with a broken file still exits non-zero, and the helper loads

* add AVX2 support for masked loading and storing in simd_gemm_ukernel_tail
* ggml-cpu: fix FA softcap handling for padded KV tiles
* metal: support left and circular padding in GGML_OP_PAD
Align Metal with CPU, CUDA and Vulkan: shift the source coordinates by
the left paddings, wrap them around with the same wrap_around when
circular, and read the source through nb00, which also fixes a right
padding of a permuted source. A test case covers it.
Drop the f32_4 kernel: its selection is disabled as slower, and it
fails two pad cases once enabled.
* metal: use a function constant for the circular pad variant
Address review from ggerganov: replace the bool template with FC_PAD,
as FC_upscale_aa does, so the pad kernel is compiled once and
specialized per pipeline.
* context : do not re-reserve the scheduler when toggling causal_attn
`llama_context::set_causal_attn()` marks the scheduler to do a full re-reserve on every change of the flag. For vision inputs, this flag is flipped twice around each non-causal image chunk for Gemma models, resulting in two expensive `sched_reserve()` passes per image. This is especially slow for multi-image or video inputs.
The cost of a re-reserve scales with context and ubatch configurations, so larger settings pay more per image (see table below).
The re-reserve is unnecessary in this case because `causal_attn` only changes the values written to KQ mask, not tensor shapes or any other buffer sizes.
Note: `causal_attn` is a graph reuse key (`llm_graph_params` via `cparams`), so a new graph is built regardless of `sched_need_reserve`, so this doesn't change the graph rebuilding behaviour.

* qwen4exp : make the indexer bias shape independent of causal_attn
The block/cell bias path was selected on cparams.causal_attn, so the
causal and non-causal graphs differed in tensor shapes and ops. With the
re-reserve removed (previous commit), a runtime flip resulted in
reallocating the compute buffers, which would fail under
GGML_SCHED_NO_REALLOC.
This commit selects the block path from the mask shape only, independent
of causal_attn. causal_attn is instead passed to set_input_qsa.
causal_attn is fixed per graph as it's part of the reuse key. Causal
values are unchanged. Non-causal values now follow the reference rule,
where every visible block competes on score and only unpooled cells are
always selected.

* vulkan: read the batch stride of an in place src0 from nb[2]
A dim01 contiguous tensor can still be a view whose batches are
strided by more than ne[1] rows, the first rows of a KV cache for
example. Both the mat-vec and the matrix paths read such a tensor in
place but passed ne00*ne01 as the batch stride, so every head past
the first read the wrong rows. The same applies to src1. The stride
now comes from nb[2] whenever the tensor is used in place; the value
is unchanged for a contiguous tensor.
test-backend-ops gets an m_v parameter on test_mul_mat, the number of
rows of a in memory, and two cases at the shapes of a decoder self
attention over a cache.
* vulkan: size the in place A and B ranges by their strided extent
The matrix path bound src0 and src1 to the shader with a range of
elements times type size, which ends before the batches of a strided
view. Pipelines with bounded access read zero past that range, so the
same view that the mat-vec path already handles gave wrong results
on Intel and on NVIDIA without coopmat2. The range now comes from
ggml_nbytes when the tensor is read in place.
* vulkan: address review from jeffbolznv
Bind the in place A and B of the matrix path with ggml_vk_subbuffer,
which spans to the end of the buffer, so a strided view is in range
without computing its extent.
mul_mat_id reads the batch stride of an in place src0 and src1 with
the same helper as mul_mat. test_mul_mat_id gets an m_v parameter,
the number of rows of as in memory, and a case whose experts are
strided by more rows than it uses.
* vulkan: read the batch stride of an in place src0 in mul_mat_vec_id
The single token path of mul_mat_id passed ne00*ne01 as the batch
stride of A, so a strided expert view read the wrong rows. The stride
now comes from ggml_vk_batch_stride like the other three paths, and
src1 follows the same rule.
test_mul_mat_id gets a single token case over the strided view.
* vulkan: address review from jeffbolznv
The batch stride of an in place tensor is taken from nb[2] as
nb[2] / type_size * block_size, which holds when nb[2] is padded and
not a multiple of nb[1]. A test_mul_mat case with a padded batch stride
covers it.
* vulkan: keep the A and B ranges exact in mul_mm
The quantized A loads of mul_mm carry no row bound and rely on the
descriptor range to read zeros past the last row of a partial tile.
Binding A and B up to the end of the buffer let those tiles read the
leftovers of a previous node and hung the NVFP4 mul_mm on NVIDIA
without coopmat2. The range is the strided extent of a tensor read in
place and the staged size otherwise.
* server : allow splitting RANK pooling for causal LLM rerankers
Rerank models fall into two categories: bidirectional cross-encoders
(BERT, etc.) that require all tokens in a single physical batch, and
causal LLMs repurposed as rerankers (Qwen3, Qwen3-VL) that can use
chunked prefill like any other decoder.
Previously the server rejected all RANK-pooling inputs larger than
n_ubatch, and the graph builder hardcoded QWEN3/QWEN3VL arch checks to
determine last-token pooling. This broke long-document and multimodal
reranking for causal models.
Fix: expose llama_get_causal_attn(ctx) so the server can check the
effective runtime attention type (reflecting any --attention override
or set_causal_attn call). Also expose llama_model_is_causal(model)
for querying the static architectural property from GGUF metadata.
can_split() now permits chunked prefill for RANK pooling when the
context is causal. The graph builder's inline arch check is replaced
with the same cparams.causal_attn predicate, removing the duplication.

Recent PLaMo-3 models use YaRN, while some earlier PLaMo-3 models do not.
The recent PLaMo-3 store their YaRN settings as flat config keys
(rope_scaling_factor, initial_context_length) and build the dict at runtime
in Plamo3Config.rope_parameters. The current converter misses these settings
and writes plain RoPE metadata to GGUF. Mirror the runtime settings into
rope_parameters so the corresponding rope.scaling.* is written to GGUF.
The SYCL FWHT covers 64 to 512 via the standard butterfly network, plus
384/640/768/1280 via the Kronecker/Paley construction added separately in
Hadamard hint can produce (1024, 2048, 4096, 8192); those still fall through
to the default case and run as a dense GEMM against the materialized
rotation tensor, correct but O(n^2) instead of O(n log n).
fwht_kernel_wide runs one row per work-group instead of per sub-group, so
each work-item keeps N/NT values rather than N/WARP_SIZE. Butterflies below
the sub-group width still shuffle; those up to the work-group width go
through work-group local memory; the rest stay in registers. Same butterfly
and sign convention as the existing narrow kernel.
ggml's SYCL backend registration (dpct::dev_mgr) unconditionally requires a
GPU-labeled platform to exist and throws before any op-level test can run,
so test-backend-ops could not be exercised on this box (a GPU-less pod) even
via the CPU device. Verified instead with a standalone harness: the same
kernel body run through a real SYCL CPU device (Intel oneAPI DPC++ 2026.1,
OpenCL CPU backend), checked against an independent recursive-doubling
Hadamard reference, cross-validated by first running the existing unmodified
narrow kernel through the identical harness and confirming it passes (rules
out a reference-convention bug before trusting a pass on the new code).
Random-input results for all four widths, single- and multi-row:
N=1024 NT=256 rows=1 max_abs_err=1.7e-07 max_rel_err=4.9e-04 PASS
N=2048 NT=256 rows=1 max_abs_err=1.9e-07 max_rel_err=2.0e-04 PASS

N=8192 NT=256 rows=2 max_abs_err=2.5e-07 max_rel_err=1.9e-03 PASS
This covers the kernel algorithm itself; it does not exercise the ggml
dispatch/supports_op integration end to end, which needs a real GPU (or a
SYCL GPU plugin) to get past backend registration. test-backend-ops build
is verified: fwht.cpp recompiles with zero warnings as part of ggml-sycl.
