Foad Abo Dahood 88ada91c18 metal : fix idle threads in mul_mv_iq3_xxs for ne00 < 1024 (#28086)
* metal : fix half-idle simdgroup in kernel_mul_mv_iq3_xxs_f32 for ne00 < 1024

* metal : keep N_R0_IQ3_XXS = 4, dispatch a separate 8-row split kernel for ne00/32 < 32

The plain kernel is unchanged from master (4 rows per simdgroup, one thread per
chunk). The row-split mapping now lives in a separate kernel_mul_mv_iq3_xxs_f32_split
instantiation with N_R0_IQ3_XXS_SPLIT = 8, and the host selects it only when
ne00/32 < 32 and divides 32, so wide matrices keep the master kernel bit for bit.

* metal : select the iq3_xxs row split with a function constant instead of a separate kernel

Ankit Khandelwal 64e9bceb2c vulkan : fuse UNARY(GELU|SIGMOID|SILU|SOFTPLUS) + MUL (#27220)
* vulkan : fuse UNARY(SIGMOID|SILU|SOFTPLUS) + MUL

* vulkan : fuse UNARY(SIGMOID|SILU|SOFTPLUS) + MUL

- implement fusion in unary.comp behind UNARY_MUL_FUSION ifdef,
  specialized pipelines per op instead of runtime branching
- fuse adjacent nodes only, ordering handled by graph_optimize
- drop runtime consumer scan and pending_unary_mul deferral

* vulkan : fuse UNARY(GELU|SIGMOID|SILU|SOFTPLUS) + MUL

1. GELU: gelu_mul_f32/f16 pipelines registered, CREATE_UNARY_MUL(gelu), GELU in dispatch + fuse gate + perf fusion name
2. Renamed/moved: gate is now ggml_vk_can_fuse_unary_mul(cgraph, unary_idx, mul_idx), placed with the other can-fuse helpers
3. norepeat both variants: each op gets plain (spec {0}) + _norepeat (spec {1}) pipelines from the same SPIR-V, selected via ggml_are_same_shape(src0, src1); the shape gate now allows broadcast (other dims equal-or-1)
4. graph_optimize: lambda deleted; standard "// UNARY + MUL: pull the consuming MUL forward" block added alongside the SSM_CONV/ROPE/MUL_MAT reorderings, with the same "other src must be weights or already processed" readiness check

* vulkan : align unary_mul fusion with binary kernel layout, relax gelu test tolerance

- schedule the fused kernel like mul.comp (256 threads x 2 unrolled
  iterations), recovering a 10-18% prompt-processing regression
- allow 5e-7 f32 error for gelu_mul: the shader evaluates gelu with an
  exp-based tanh identity while the CPU reference uses tanhf (~1 ulp)

* vulkan : use ggml_can_repeat in UNARY+MUL fusion shape check

The fused kernel indexes src1 via per-dim fastmod (generic_binary_head.glsl),
which is exact whenever the other operand tiles into the unary result -- not
just when its dims are equal or 1. Replace the hand-rolled loop with
ggml_can_repeat(other, unary) so the check matches the kernel's actual
capability and reuses the standard helper. Argument order matters: reversed,
it would wrongly admit graphs where the unary result is mul->src[1] and the
other operand is larger, producing truncated output.

Also add a rep_ne0 layout to the fused unary+mul backend tests covering a
non-1 repeat factor along dim 0.

* vulkan : fuse UNARY+MUL pairs separated by zero-compute nodes

gemma4's per-layer embedding gating builds gelu -> view_2d_slice -> mul,
where the intervening view is a zero-compute node aliasing an input that
was computed much earlier. Strict adjacency requirements meant neither
CUDA nor the vulkan unary+mul fusion handled this pattern.

Extend ggml_vk_graph_optimize to detect a UNARY whose consuming MUL is
separated only by unscheduled zero-compute nodes (GGML_OP_NONE, VIEW,
RESHAPE, TRANSPOSE, PERMUTE) and schedule those nodes ahead of the pair,
making it adjacent so the existing fusion applies. The reorder is guarded
by ggml_vk_can_fuse_unary_mul, a source-availability check for every
interleaved node, and the protected fusion patterns (topk_moe*, snake);
if fusion is later rejected the reordered graph still executes correctly,
just unfused.

Add a view_mid layout to the fused unary+mul backend tests replicating
the gemma4 pattern.

* vulkan : support OP-on-B in UNARY+MUL fusion

Some models apply the unary activation to the smaller MUL operand, e.g.
qwen3next/qwen35moe shared-expert gating builds ffn_shexp * sigmoid(gate)
with a [1,n_tokens] gate tensor. This shape was correctly rejected before:
the fused kernel derives its iteration extent from the unary tensor and
would leave most of the destination unwritten, and the generic same-shape
requirement in ggml_can_fuse blocked the pair outright.

Add UNARY_MUL_B_FUSION shader variants computing dst = src0 * OP(src1):
the OP operand rides the existing per-dim fastmod indexing, while the
iteration extent now comes from mul. Route {UNARY, MUL} pairs through a
local can-fuse variant that drops the generic same-shape rule and instead
requires the unary result to tile into mul->src[0] (ggml_can_repeat);
pairs with the unary as src0 keep the previous direction check, and
equal-shape pairs keep using the original pipelines.

Add a "gate" layout to the fused unary+mul backend tests covering the
shared-expert gate shape for gelu/sigmoid/silu/softplus in f32 and f16.

* vulkan : fold unary+mul view-hoisting into graph_optimize dep checks

Replace the dedicated UNARY + EMPTY* + MUL scanning block with two small
extensions to the existing scheduling logic:

- a consuming MUL may now join its in-set UNARY across a gap of unused
  zero-compute nodes (NONE/VIEW/RESHAPE/TRANSPOSE/PERMUTE), instead of
  requiring strict adjacency
- while doing so, such zero-compute blockers are ignored for this pair

Fusion validity is still decided later by ggml_vk_can_fuse at dispatch
time, so a rejected pair simply executes adjacent-but-unfused. Note the
relaxation must stay scoped to this pattern: exempting zero-compute
blockers globally reproduces silent output corruption on gemma3n.

* vulkan : select unary_mul OP-on-B via specialization constant

Replace the UNARY_MUL_B_FUSION compile-time shader variants with an
op_on_b specialization constant on the existing unary_mul SPIR-V,
mirroring how the norepeat flag is handled. The four {op}_mul_b_{f32,f16}
shader artifacts are gone - the OP-on-B pipelines reuse the base SPIR-V
with two-entry {norepeat, op_on_b} spec lists - and the duplicated store
expression is collapsed into a single runtime branch that the driver
prunes per specialization.

The constant is declared only under UNARY_MUL_FUSION so every other
binary pipeline keeps its single-entry specialization list.

* vulkan : replace unary_mul pipeline switches with a lookup table

Collapse the four nested selection switches in ggml_vk_unary_mul into a
single indexed lookup against a pipeline_unary_mul[4][2][2][2] table
([unary op][f16][norepeat][op_on_b]), whose trailing dims mirror the
{norepeat, op_on_b} spec constant list. The op axis uses a small shared
index helper that also replaces the switch in ggml_vk_can_fuse_unary_mul,
making it the only place that maps ops to the table.

Pipeline names are unchanged. Adding another supported op now requires
one macro invocation line and one helper case instead of edits in four
separate switches.

* vulkan : use ggml_can_fuse_subgraph for unary_mul pairs

Replace the hand-rolled pair validation in ggml_vk_can_fuse_unary_mul_pair
(bounds, op match, compute flags, single-use elision) with the shared
ggml_can_fuse_subgraph helper; backend-specific shape/type rules remain in
ggml_vk_can_fuse_unary_mul. Unlike ggml_can_fuse, the subgraph helper has
no same-shape requirement, so it covers both operand slots including
OP-on-B gates, and additionally rejects intermediates flagged as graph
outputs and validates view-source confinement.

The outputs parameter takes absolute node indices into the cgraph.

* Fix Whitespace

* vulkan : drop redundant unary_mul gap check in graph_optimize

The zero-compute nodes separating a UNARY from its consuming MUL are
already scheduled ahead of the pair by pass 2 of an earlier
optimization window, so the scoped gap tolerance added for this pattern
is unreachable in practice - disabling it leaves gemma-3n dispatch
counts unchanged (841 GELU_MUL per pass). Remove the flag, the empty
blocker exemption, and the now-unused gap helper, restoring the strict
adjacency requirement of the UNARY -> MUL pull-forward.

Keep the relaxation scoped out entirely: generalizing "zero-compute
nodes never block" beyond this pattern previously reproduced silent
output corruption on gemma3n.

* vulkan: fix whitespace (tab in indent)

* vulkan: fix whitespace (extra blank line)

* vulkan : move op_on_b spec constant to unary.comp

op_on_b is only used by the fused unary*mul path. Keep
generic_binary_head.glsl generic by defining it in unary.comp
instead. Same constant_id=1 and guard, no functional change.

* vulkan : make RMS_NORM/UNARY fusion gap-tolerant for views

Strict j==c+1 blocked RMS_NORM->MUL and UNARY->MUL when a
VIEW sits between (e.g. rms_norm -> view -> mul). Allow
c==back() with an empty-or-scheduled gap, matching the
review suggestion to check src linkage instead of adjacency.
Scoped to the two blessed pairs; safe because gaps can only
contain zero-compute nodes.

miyan f014bfef8b Fix Vulkan-Hpp handle usage on 32-bit targets. (#22892)
On 32-bit platforms, Vulkan non-dispatchable handles such as VkBuffer are
represented as uint64_t, and Vulkan-Hpp disables implicit conversions for
type safety. This exposes two issues in ggml-vulkan:

1. vk::Buffer is streamed directly into std::ostream in debug/memory logs.
2. vk::Buffer is cast to VkBuffer before being passed to Vulkan-Hpp
   CommandBuffer::copyBuffer APIs.

Fix these by add the operator<< for vk::Buffer, and
by passing vk::Buffer directly to Vulkan-Hpp copyBuffer calls.

Piotr Wilkin (ilintar) 895c045fd1 chat : split specialized parsers into common/parsers (#27764)
* chat : split specialized parsers into common/parsers

Move the 14 dedicated template parsers out of chat.cpp into one file each under
common/parsers, mirroring the src/models split. chat.cpp keeps the template
detection in common_chat_try_specialized_template() and drops from 3915 to 1513
lines.

common/parsers/parsers.h holds the shared helpers and one declaration per
parser. foreach_function/foreach_parameter become inline there since nothing in
chat.cpp uses them any more; common_chat_template_direct_apply_impl and
common_chat_template_generation_prompt_impl lose static and carry their default
arguments in the header. Parser-specific helpers move with their parser:
is_lfm2_template, deepseek_v4_sort_tool_results and the gemma4 turn builder.

No functional change.

* chat : enumerate parser sources instead of globbing

file(GLOB) does not re-run CMake when a source file is added or removed, so an

Pascal f114f91f9e tests : initialize the L2_NORM batch array (#28553)
* tests: bind the L2_NORM batch count to a local

GCC cannot prove the loop fills norms up to the index read after it
while the bound is a class member, so it reports a maybe uninitialized
use. Reading the count once into a local restores the tracking.

* tests: initialize the L2_NORM batch array

The read after the fill loop is only provably defined once the array
carries an initializer, which GCC 12 requires on the aarch64 Release
build where warnings are fatal.

* server: fix LRU hang on multiple requests same model

* server: keep a queued model out of the victim pool until its waiters leave

A waiter that gave up while its model was still loading left the
model idle with no request behind it, and nothing recounted the free
slots, so a second request queued behind it stayed queued forever.
tick() was only driven by requests: join, claim and the end of a
proxied request.

Keep the queue entry alive after a successful claim so the model
coming up is never picked as a victim before its waiters use it, and
recount the slots on every status change and whenever a waiter
abandons the queue. The model is then evicted as soon as it comes up
with nobody left to serve.

Kevin HopperandKevin Hopper 7a333e7240 vulkan: add DeepSeek-V4 hyper-connection fused ops (DSV4_HC_COMB/PRE/POST) (#26578)
* vulkan: add DeepSeek-V4 hyper-connection fused ops (DSV4_HC_COMB/PRE/POST)

CUDA has these ops from the DeepSeek-V4 merge and Metal gained them in
PR 26459. Vulkan was the last major backend running the unfused primitive
chain. On DeepSeek-V4-Flash the unfused Sinkhorn comb chain alone takes
about 32% of decode op time on gfx1151 (Strix Halo), spread over roughly
16k dispatches per token.

dsv4_hc_comb runs the full 20-iteration Sinkhorn in registers. A token's
4x4 comb matrix lives in 16 consecutive subgroup lanes, with idst in bits
0-1 and isrc in bits 2-3 to match the CPU reference layout, so
subgroupShuffleXor by 1|2 reduces rows and by 4|8 reduces columns. One
dispatch replaces about 137 strictly ordered node executions per site.
The shuffle masks never cross a 16-lane boundary, so a subgroup of size
64 packs 4 independent tokens.

dsv4_hc_pre and dsv4_hc_post handle the elementwise stream collapse and
fan-out, with per-token coefficients staged in shared memory.

GGML_VK_DISABLE_DSV4_HC disables all three ops. The _COMB, _PRE and
_POST variants gate each op independently so a single kernel can be
bisected against the unfused graph.

Adds eval cases at the production n_iter=20 across batch sizes that
cross subgroup and workgroup boundaries.

* vulkan: dsv4 hc review fixes

Drop the per-op env-var disables and device flags, the stride divisibility
check (ggml guarantees it) and the workgroup-count fallback in supports_op.
Trim the comb shader comments to the lane layout.

Jeff BolzandAiChiTuDouPian 0cae43063c vulkan: support type-aligned GET_ROWS (#28253)
* vulkan: fall back to CPU for GET_ROWS with misaligned offsets

The Vulkan GET_ROWS shader asserts when a tensor's backing-buffer offset
plus view_offs is misaligned w.r.t. minStorageBufferOffsetAlignment
(see init_pushconst_tensor_offsets). Previously this caused a hard crash
on models using ggml_view + ggml_get_rows (e.g. Qwen3-TTS, Qwen3-VL).

Return false from supports_op() in the misaligned case so the scheduler
falls back to CPU, matching the existing pattern for PAD_REFLECT_1D and
other unsupported op/shape combinations.

Repro: llama-tts -m Qwen3-TTS-*.gguf -mm mmproj-*.gguf -ngl 99
Crash: GGML_ASSERT(dst->op != GGML_OP_GET_ROWS || (a_offset == 0 && ...)) failed

* vulkan: trim comment for GET_ROWS misalign fallback

* vulkan: fix file corruption in gated_linear_attn struct

* vulkan: properly handle misaligned offsets in GET_ROWS quantized path

- get_rows_quant.comp was missing get_aoffset()/get_boffset()/get_doffset()
  calls that are already present in get_rows.comp, causing GGML_ASSERT crashes
  when GET_ROWS operates on views with non-zero view_offs, as produced by
  KV cache slices in Qwen3-TTS and Qwen3-VL.
- Remove the defensive misalignment GGML_ASSERT in init_pushconst_tensor_offsets
  for the binary push-constants specialization, since both get_rows.comp and
  get_rows_quant.comp now correctly apply per-tensor base offsets.
- Remove the workaround CPU fallback in supports_op() for GET_ROWS, since the
  Vulkan backend now handles misaligned offsets natively (no more bailout).
- Add backend test coverage with view_src0=true (ggml_view_4d into a padded
  tensor) for F32, F16, Q4_0, Q4_K, Q8_0, and I32 types, exercising both the
  non-quantized (get_rows.comp) and quantized (get_rows_quant.comp) paths
  with non-zero view_offs that reproduce the original Qwen3-TTS crash.

* tests: trim redundant comments in test_get_rows vs0 region

* tests: trim redundant comments in test_get_rows vs0 region (follow-up)

* vulkan: bind tensor base for binary ops, pass full view_offs via push constants

For ops using vk_op_binary_push_constants (GET_ROWS, ADD, SUB, MUL, etc.),
bind the view_src base and pass the full view_offs divided by type_size via
push constant misalign_offsets. This avoids truncation when misalign_bytes is
not a multiple of quantized block size.

ggml_vk_tensor_subbuffer gains a use_view_offs parameter. When false, the
binding points to vk_tensor_offset (base) and size includes view_offs.
init_pushconst_tensor_offsets<binary> computes a/b/d_offset directly from
tensor->view_offs, which is always row-aligned and therefore exact.

Added non-zero view offset (offset_rows=3) backend tests for GET_ROWS across
all_types with be1={1,7}, v={false,true}, skipping gradient setup for view
tensors (GGML_OP_VIEW fails ggml_set_param).

All 223 GET_ROWS tests pass on Vulkan (NVIDIA RTX 5060 Ti).

* vulkan: bind aligned offset for binary ops, pass adjusted misalign via push constants

For ops using vk_op_binary_push_constants (GET_ROWS, ADD, SUB, etc.), bind
the buffer to an aligned position near the view offset (not the tensor base)
and pass the adjusted misalignment via push constants.

ggml_vk_get_adjusted_misalign finds the smallest misalign that is both a
multiple of minStorageBufferOffsetAlignment and type_size, ensuring
misalign/type_size is exact (no truncation for quantized block types).

ggml_vk_tensor_subbuffer gains use_view_offs parameter. When false, binds
to (target - adjusted_misalign) instead of the view_src base, keeping the
offset small enough for 16-bit/8-bit push constant fields.

Added non-zero view offset (offset_rows=3) backend tests for GET_ROWS across
all_types with be1={1,7}, v={false,true}, skipping gradient setup for view
tensors (GGML_OP_VIEW fails ggml_set_param).

All 223 GET_ROWS tests pass on Vulkan (NVIDIA RTX 5060 Ti).

* vulkan: bind aligned offset for binary ops, fix UMA offset mismatch

For ops using vk_op_binary_push_constants (GET_ROWS, ADD, SUB, etc.), bind
the buffer to an aligned position near the view offset (not the tensor base)
and pass the adjusted misalignment via push constants.

Added ggml_vk_tensor_physical_offset to unify physical offset lookup across
UMA and non-UMA devices. On UMA, resolves via ggml_vk_host_get(tensor->data);
otherwise uses vk_tensor_offset(t) + t->view_offs. Both get_misalign_bytes and
the new ggml_vk_get_adjusted_misalign helper build on top of this function,
so buffer bindings and push constant offsets are always consistent regardless
of device memory model.

ggml_vk_get_adjusted_misalign finds the smallest misalign that is both a
multiple of minStorageBufferOffsetAlignment and type_size, ensuring
misalign/type_size is exact (no truncation for quantized block types) while
remaining small enough for 16-bit/8-bit push constant fields
(adjusted_misalign < lcm(align, type_size)).

ggml_vk_tensor_subbuffer gains use_view_offs parameter. When false, binds
to (physical_offset - adjusted_misalign) on both UMA and discrete GPUs,
fixing a bug where the UMA host_get path previously skipped the adjusted
misalign binding and returned the target offset directly.

Added non-zero view offset (offset_rows=3) backend tests for GET_ROWS across
all_types with be1={1,7}, v={false,true}, skipping gradient setup for view
tensors (GGML_OP_VIEW fails ggml_set_param).

All 223 GET_ROWS tests pass on Vulkan (NVIDIA GeForce RTX 5060 Ti).

* finish misalignment fix

* supports_op changes for openvino/webgpu

Daniel Bevenius 1173700b9c examples : print ggml_version and ggml_commit in test-cmake [no ci] (#28538)
This commit adds the printing of the ggml version and commit to the

The motivation is just to be able to quickly verify that the correct

DevVexusandClaude Opus 5 9a7570587c convert : write explicit recurrent_layers for Qwen3-Next / Qwen3.5 (#28208)
Problem
- Loader prefers `<arch>.attention.recurrent_layers`, falls back to `full_attention_interval` if missing
- Converter only ever writes the interval. gguf-py has no constant/writer for the array
- Interval can only describe evenly spaced full-attention layers. Any non-uniform `layer_types` gets reconstructed wrong
- No error, no warning. Model loads, runs, wrong layers get wrong ops. Full-attn layers marked recurrent lose their KV cache
- Every published Qwen3.5 checkpoint is uniform so nobody's hit it yet

Repro
12 layers, periods 4/3/5:

    layer:  0 1 2 3 4 5 6 7 8 9 10 11
    actual: L L L F L L F L L L  L  F
    loader: L L L F L L L F L L  L  F
                        ^ ^

Layer 6 is full attn, loaded as recurrent. Layer 7 the reverse.
52-layer non-uniform stack: 15/52 mis-typed.

Fix
- `constants.py`: add `Keys.Attention.RECURRENT_LAYERS` (name already registered in llama-arch.cpp)
- `gguf_writer.py`: add `add_recurrent_layers()`, same shape as `add_rope_pattern()`
- `conversion/qwen.py`: emit array from `layer_types` in `Qwen3NextModel.set_gguf_parameters` (covers 3-Next, 3.5, 3.5-MoE)

Notes
- Array is padded with `false` for MTP blocks. `get_key_or_arr` checks length against `n_layer_all`, which includes MTP. Matches the fallback's `i < n_layer()` guard
- Interval is still written. Old builds only understand the interval
- `layer_types` length != `num_hidden_layers` now raises in converter instead of producing a GGUF that fails at load

Tested
- End-to-end on a 62-layer non-uniform Qwen3.8-27B (2 linear layers removed). Loader reads the array, 62 blocks, 0 mismatches. Without fix: interval fallback, mis-typed
- MTP padding NOT tested on a real MTP model. Reasoned from qwen35.cpp + get_key_or_arr. Would appreciate a check

Daniel Bevenius 2092353c8b ci : add container image checking and tagging (wip) (#28394)
This commit contains a suggestion for handling container images which
are currently not semver tagged, they only have build numbers in there
tags.

The proposed solution here is to first add a check to make sure that
there are container images built for the build number of the release and
if not fail the build. The container images are build nightly but they
can be triggered manually as well.
If the the container images check passes then the make-release workflow
will re-tag the images with the semver.

Anjielon 8fe90e1fbf vulkan: add TQ1_0 support (mm, mat-vec, mat-vec-id, dequant, get_rows) (#27765)
* vulkan: add TQ1_0 support (mm, mat-vec, dequant, get_rows)

* vulkan: pack TQ1_0 powers of 3 into a 32-bit constant

Replaces the constant array with a packed 32-bit value (7 bits per entry,
max 81 < 128) extracted with shift/mask, as suggested in review — avoids a
constant array that may not be kept in registers.

test-backend-ops on gfx1151: tq1_0 MUL_MAT 11/11, MUL_MAT_ID 6/6,
GET_ROWS 4/4, unchanged.

* vulkan: address review - shared TQ1_0 decode helpers, fix standalone dequant shader

Review feedback from jeffbolznv, all points:

- Move the packed-pow3 decode into shared helpers in types.glsl
  (tq1_0_byte_of / tq1_0_digit_of / tq1_0_trit) and use them from
  dequant_funcs.glsl, mul_mm_funcs.glsl, dequant_funcs_cm2.glsl and
  dequant_tq1_0.comp instead of repeating the logic. The cm2 path also
  drops its constant array for the packed-constant extraction.
- Translate all remaining comments to English.
- dequant_tq1_0.comp: use dequant_head.glsl. The shader previously declared
  its own single-field push constant while the pipeline is created with the
  5-field layout, so p.ne read the wrong field - confirmed broken, as
  suspected in review.
- Fix wg_denoms for the standalone dequant pipeline: one invocation decodes
  4 elements with local_size 256, so a workgroup covers 256*4 elements, not
  256*16. With the old value the dispatcher launched a quarter of the
  required workgroups.

Verified by temporarily forcing the dequant + f16 matmul path for TQ1_0
(hack not committed): test-backend-ops MUL_MAT passes through the rewritten
standalone shader, and the standard MUL_MAT / MUL_MAT_ID / GET_ROWS
tq1_0 cases still pass on Vulkan (AMD gfx1151).

* vulkan: address review — English comments, shared tq1_0_trit, trim TQ1_0 test cases

- mul_mat_vec_tq1_0.comp: drop leftover non-English comment and the local
  POW3_PACKED constant; all decode sites now call tq1_0_trit() from types.glsl
- types.glsl / dequant_funcs_cm2.glsl: ASCII-only, drop stale reviewer note
- test-backend-ops: remove the oversized MUL_MAT_ID case (432 MiB A tensor,
  ~172 GFLOP reference); move the two remaining ones next to the other
  backend-specific mul_mat_id one-offs and document why they are needed

* metal: decline TQ1_0 for GET_ROWS and mat-mul in supports_op

The new TQ1_0 cases in test-backend-ops exposed that the Metal backend
claimed support for GET_ROWS/MUL_MAT/MUL_MAT_ID with TQ1_0 sources while
having no such kernels (ggml_metal_library_compile_pipeline aborted on the
missing kernel_get_rows_tq1_0). Decline the type so the ops fall back to
the CPU, matching the existing NVFP4 handling on the same lines.

Assisted-by: Claude Fable 5

* vulkan: trim the TQ1_0 comments

Addresses @0cc4m's review: keep only what the code does not already say.

Removed the block-format recaps (the layout is right there in the struct) and
the step-by-step decode walkthrough. Kept the two facts a reader cannot infer:
the 8-bit truncation is part of the format, not an optimisation, and the powers
of 3 are packed into one uint so they do not end up in a constant array that
may miss the registers.

No functional change.

* vulkan: address review — trim comments, fold Metal check, drop unused _v

Per @0cc4m's review:

- dequant_funcs.glsl, dequant_funcs_cm2.glsl: drop the "see types.glsl"
  pointers — they apply to every quant and say nothing specific.
- dequant_tq1_0.comp: drop the wg_denoms note. It is a precondition, not
  information.
- mul_mm_funcs.glsl: same pointer removed.
- types.glsl: the comment on tq1_0_trit is down to the one fact the code
  cannot show — the 8-bit truncation is part of the format, matching the C
  reference, not an optimisation.
- dequant_funcs_cm2.glsl: removed dequantFuncTQ1_0_v and its define. You were
  right that it is optional: it wrapped four scalar decodes and vectorised
  nothing, and mul_mm_cm2.comp already guards the path with
  `#if defined(dequantFuncA_v)` (DATA_A_F32 omits it the same way).
- ggml-metal-device.m: folded TQ1_0 into the existing NVFP4 check instead of a
  separate block, and dropped both comments.
- test-backend-ops.cpp: the two mul_mat_id cases stay — they cover the
  block-stride loop and the per-expert base offset that k == 256 alone never
  reaches — but the comment is now one line instead of five.

Kept: the one-line labels on the three block regions in mul_mat_vec_tq1_0.comp
and on tq1_0_byte_of(). Those state the 5-trits-per-byte packing, which the
loop bounds do not show. Happy to remove them too if you prefer.

Re-verified on AMD gfx1151 (Vulkan), test-backend-ops, 2/2 backends passed:
MUL_MAT 9 TQ1_0 cases, MUL_MAT_ID 5, GET_ROWS 4 — all OK, no failures.
The coopmat2 path is unchanged apart from the removed _v define.

Daniel HanandGeorgi Gerganov 5fdfa62829 models : fix GDN normalization from max to rsqrt (#28068)
* models: use flash-linear-attention's l2norm for gated delta net q/k

The GDN q/k normalization is defined by flash-linear-attention as

    l2norm(x) = x * rsqrt(sum(x*x) + eps)

with eps inside the root. Every GDN call site in the tree uses ggml_l2_norm
instead, which is x / max(sqrt(sum(x*x)), eps), i.e.
torch.nn.functional.normalize - its CUDA kernel cites that page.

The clamp never engages at these magnitudes, so in practice llama.cpp
normalizes with no epsilon at all where the reference has one inside the
root.

transformers made the same substitution when it first added Qwen3-Next and
corrected it three days later in huggingface/transformers#40842, 'Fix the
misalignment between the l2norm in GDN of Qwen3-Next and the implementation
in the FLA library'. vLLM and SGLang vendor FLA rather than reimplementing
it, so neither ever had the clamp.

eps keeps coming from the checkpoint, exactly as every call site already
passed it. The references hardcode 1e-6 for this norm; that is a separate
question and the two agree on every GDN checkpoint in the wild.

ggml_l2_norm itself is correct and unchanged, as is rwkv7-base, its original
caller, which passes normalize's own default eps of 1e-12.

No new ggml op: rms_norm already carries eps inside the root, so
rms_norm(x, eps/n) * (1/sqrt(n)) is exactly x * rsqrt(sum(x*x) + eps).

Aleksander Grygier 0afb805b19 ui: Improve Chat Messages rendering performance (#28460)
* ui : update active conversation fields in place

updateCurrentNode, applyConversationUpdate, updateConversationTimestamp
and the pin toggle replaced the whole activeConversation object, so its
identity changed on every send, tool result and rename. ChatMessages
tracks that identity to refresh sibling info, so each replacement
triggered a full refetch of every message in the conversation. Write the
changed fields instead, mirroring updateMessageAtIndex.

Assisted-by: pi:zai-org/GLM-5.3

* ui : reuse the conversation load read for sibling info

Opening a conversation read every message from the database twice: once
in loadConversation for the active path, once in ChatMessages for the
sibling map. Hand the freshly read array over once so the chat screen
builds sibling info from it, and set the conversation and its messages
in one sync block so effects never see the new conversation paired with
the previous one's messages.

Assisted-by: pi:zai-org/GLM-5.3

* ui : memoize leaf walks in sibling map build

buildSiblingInfoMap resolves each sibling's leaf by walking the last-child
chain, once per sibling per message, so the walk repeats along the same
chains for every message in the conversation ( O(messages^2) on long
chats ). Memoize leaf resolution per build with path compression so each
edge is walked once.

Assisted-by: pi:zai-org/GLM-5.3

* ui : skip sibling refetch for in-place message edits

refreshAllMessages refetches every message of the conversation just to
rebuild sibling info, but preserve-responses and non-branching assistant
edits never create branches, so the sibling map stays valid. Refresh only
after actions that branch (editWithBranching kept) or delete.

Assisted-by: pi:zai-org/GLM-5.3

* ui : drop unused currentResponse reactive writes

Nothing reads chatStore.currentResponse, but setChatStreaming reassigned
it on every streamed chunk, so each token paid a reactive write and string
assignment for nothing. Remove the field and the clearUIState wrapper
that only reset it.

Assisted-by: pi:zai-org/GLM-5.3

* ui : reuse completed agentic turn sections during streaming

deriveAgenticSections runs in a $derived invalidated per streamed chunk,
but re-derived every turn of the session each time, so per-chunk cost grew
with session length. Cache completed turns keyed by their assistant message
plus reference checks on every field that feeds derivation; only the
streaming turn recomputes. Cache hits return the same section objects, so
tool block props stay stable and skip their per-chunk re-derive.

Assisted-by: pi:zai-org/GLM-5.3

* ui : share markdown block infrastructure

Every markdown block duplicated shared work: a full copy of the hljs
theme CSS per instance, and the remark/rehype plugin chain rebuilt on
every processMarkdown call ( once per block at mount, again per coalesced
chunk while streaming ). Use the single theme style element already
maintained by SyntaxHighlightedCode, and build pipelines once - shared
process-wide for attachment-less blocks, cached by attachments identity
otherwise.

Assisted-by: pi:zai-org/GLM-5.3

* ui : measure assistant layout only for the last message

Every assistant message ran getComputedStyle, getBoundingClientRect and
a ResizeObserver over the previous user bubble at mount, even off-screen
ones, forcing a layout pass per message while a long conversation
renders. The measured vars only feed the :last-child min-height rule, so
gate the effect on isLastAssistantMessage; one measurement and one
observer remain, and the effect re-runs when the last message changes.

Assisted-by: pi:zai-org/GLM-5.3

* ui : trim whole-blob scans in tool block headers

Tool block headers parsed their entire blobs at mount, even collapsed,
and most tool results and args are large plain text or embedded file
content: skip JSON.parse unless the blob starts with a JSON container,
prefilter search-result extraction with a Title:/URL: substring check,
and match the end-anchored exit-code marker against only the tail of exec
outputs.

Assisted-by: pi:zai-org/GLM-5.3

* ui : parse write_file and edit_file titles without the content blob

Both block headers parsed the full args JSON at mount, even collapsed, and
write_file and edit_file args embed the whole file content or edit
strings, so every block paid a full-blob JSON parse just to read the path.
Split the meta into a title tier that extracts the path with a targeted
key match (full parse only as fallback) and a body tier that keeps the
full parse; Svelte deriveds are lazy, and the body snippet renders only
while the block is expanded, so collapsed blocks no longer parse args.

Assisted-by: pi:zai-org/GLM-5.3

* ui : mount chat messages lazily near the viewport

Every message row mounted its full component tree on load, so the cycle
collector, GC and layout invalidation kept walking every live object and
DOM node even for rows the user never scrolls to - which dominated the
profile of long conversations. Wrap each row in a placeholder with an
IntersectionObserver ( two viewport heights of runway ) that swaps in the
real ChatMessage when the row approaches the viewport; the row shell
keeps the content-visibility sizing, and rows stay mounted once
realized. Rows targeted by the pending-edit flow mount eagerly.

Assisted-by: pi:zai-org/GLM-5.3

* ui : smooth the chat navigation animations

Slide the centered new-chat form to the bottom edge with a transform
instead of a bottom offset - layout-property transitions need the main
thread every frame and stutter while a long conversation loads, while
transform transitions run on the compositor. Fade the message list in
with a CSS animation keyed to the conversation id, disabled under
prefers-reduced-motion.

Assisted-by: pi:zai-org/GLM-5.3

* ui : follow the svelte runes guidance in chat message code

Two effects detected changes with manual previous-value refs and reset
flags. The permission request carries object identity, so its dismissal
is now a derived comparing the dismissed request; the continue request
is a bare boolean, so its dismissal only shrinks to a reset while no
request is pending. Also drop a dead if (browser) guard in the markdown
theme loader - effects never run on the server.

Assisted-by: pi:zai-org/GLM-5.3

* test : pin the chat perf invariants in the unit suite

Cover the fixes whose silent regression would be stale or wrong UI rather
than a crash: the turn-section cache must reuse unchanged turns yet
recompute on every field it compares; the sibling map must resolve the
same leaves after the leaf-walk memoization; the active conversation must
keep its identity through field updates; and the blob gates ( exec tail
window, plain-text result gate, search prefilter ) must keep accepting
what they gate. Only the risky invariants are pinned - no coverage for
coverage's sake.

Assisted-by: pi:zai-org/GLM-5.3

* refactor : address review remarks

Name the tool-arg string-field pattern, move the file tools' path field
aliases and the JSON container gates into lib/constants, and export the
write_file / edit_file meta types from $lib/types instead of the parser
modules.

Nick Farrell cd8cdf397d sycl: attribute device allocations by site (GGML_SYCL_MEMTRACE) (#27631)
define two new environment variables to better understand how much
memory is being allocated, and when. This has been invaluable in
inproving the --fit algorithm, and is likely to be useful when debugging
other memory-related issues.

`-lv 4` will be required to enable the following:

GGML_SYCL_MEMTRACE=1 will show per-site memory usage, updated whenever
it increases by more than 64MiB.
GGML_SYCL_MEMTRACE=2 will show every allocation and deallocation.

To change the default 64MiB threshold for reporting memory usage increases, use
GGML_SYCL_MEMTRACE_STEP.

A sample log line:
[SYCL-MEMTRACE] device memory query (dev): total 59493 MiB, free  4494, in use 54998; allocated     0 (buffers     0 + scratch     0), peak     0 MiB

Hongqiang Wang 1548a240e3 opencl: extend the elementwise and data‐movement op coverage (#27633)
* opencl: add extended elementwise unary ops (sgn, step, elu, hardswish, hardsigmoid, floor, ceil, round, trunc)

Adds nine GGML_UNARY_OP_* elementwise ops that were falling back to CPU on the
OpenCL backend, following the same variant shape as the existing ABS op: f32,
f32_4 (vec4), f16, f16_4 (vec4), and stride-addressed f32_nc / f16_nc for
non-contiguous inputs. New kernels/unary_ext.cl (macro-generated), a shared
ggml_cl_unary_ext dispatch helper mirroring ggml_cl_abs, the supports_op cases,
and the compute-forward cases.

Values are computed in float (the f16 variants read/write half and convert), so
the conditional ops (step, elu) match the CPU reference; the vec4 forms use
select() for the branch.

Validated with test-backend-ops on Adreno 840 and 850 (E17): all nine ops pass
every case including the vec4 and non-contiguous variants (8/8 or 14/14).

* opencl: dispatch a contiguous f32 copy over the whole device

kernel_cpy_f32_f32 maps one workgroup to each (i01,i02,i03) row and strides the
row across that workgroup's lanes, and the host launches ne01*MIN(64,ne00) work
items. A tensor with few long rows therefore runs on a single workgroup. The
mamba2 and gated-delta-net recurrent state cache is one row of 524288 floats,
copied once per layer per graph, and lands on 64 work items.

When both sides are contiguous the copy is a linear move, so dispatch it over
the whole device: one work item per float4. Gated on ggml_is_contiguous for both
tensors and equal element counts, so copies already spread over many rows keep
the existing path. The kernel is created optionally, so a driver that rejects it
falls back rather than aborting.

vload4/vstore4 rather than a float4 cast: they require only the scalar type's
alignment, and these buffers carry an arbitrary 4-byte view offset.

CPY, DUP and CONT are 217/217 on Adreno 840 and 740 with the path enabled and
disabled. GGML_OPENCL_CPY_FLAT=0 forces the old kernel.

* opencl: support all easy-copy types in CONCAT

CONCAT was F32-only. Extend it to every "easy-copy" type -- any non-quantized
type with a block size of 1 and an element size of 1, 2, 4 or 8 bytes, i.e.
f16/bf16/i8/i16/i32/i64 as well as f32.

The kernels are keyed by element SIZE rather than by type, which is what CUDA
already does for the same op: one kernel per byte width (b1/b2/b4/b8) plus the
packed b4 fast path, instead of one per ggml type. supports_op gates on the
same property, so a new type of a supported width is picked up with no further
work.

Validated with test-backend-ops on Adreno 840 / A8X and X2-90 / X2E.
