The Tensor API mat-mat path of kernel_mul_mm (GGML_METAL_HAS_TENSOR) fed a
static K=32 tile to the matmul2d op on every iteration. On the last, partial
K tile (ne00 % 32 != 0) the src1 slice extends past the K extent of the
tensor, and the op reads those out-of-bounds elements (undefined behavior per
the MSL specification, section 2.22.2). Depending on stale memory contents,
this corrupted the result or produced NaN.
Make the matmul2d op use dynamic_extent for K, and clamp the K extent of both
operand tensor views to the remaining valid K range (min(32, K - loop_k)) per
iteration, so the op reads exactly the valid K range on every iteration
(mirroring the tail handling of the MPP matmul2d examples). On K-aligned
inputs the clamp degenerates to the full 32-wide tile: the only difference
from the static-K op is that the dynamic-K op derives K from the operand
extents and edge-checks the tile against the tensor extents (a handful of
integer ops per iteration).
Add test-backend-ops MUL_MAT cases with K not a multiple of 32 to exercise
the unaligned K path.

* opencl: decline KV-convert flash_attn variants on Adreno A7X (compiler SIGSEGV)
The Adreno 740 (A7X) compiler E031.41 crashes inside clBuildProgram when
building the flash_attn programs whose KV path is mixed-type or dequantized:
flash_attn_f32_f16, flash_attn_f32_q8_0, flash_attn_f32_q4_0. It is a driver
crash rather than a compile-error return, so build_program_from_source_ex()
cannot catch it. The uniform f32 and f16 programs build correctly.
Decline the three KV-convert variants on the A7X in supports_op so they never
lazy-compile; those attention layers run on the CPU backend instead. Same
idiom as the existing Intel DK=512 and X1E carve-outs.
test-backend-ops FLASH_ATTN_EXT on the 740: 226 OK / 0 FAIL, previously exit
139. Other parts are unaffected - the gate is dead code there.
* opencl: fix q6_K flat mul_mat on older Adreno E031 compilers, gated
kernel_mul_mv_q6_K_f32_flat produces ~10x-wrong output on the older Adreno
E031 compilers while q4_K and q5_K are correct. Four codegen defects, each
confirmed on-device against the CPU reference:
1. 64-bit ulong arithmetic is miscompiled, so every weight and scale read
hit the wrong address - the primary cause, and why q5_K (int offsets)
was unaffected. The block index is computed in int and widened only
inside the pointer expression.
2. The vectorized dequant (int4/float4 bit-ops, convert_*4, dot()) is
miscompiled; the 6-bit weights are reconstructed and the dot done
scalar.
3. vload4 of the f32 activations is miscompiled; replaced by a
scalar-indexed load.
4. The accumulation is miscompiled unless a side effect forces the partial
sums to materialize. A printf under a guard the compiler cannot prove
false acts as a zero-cost optimizer barrier; its placement is
load-bearing.
The defect tracks the compiler, not the GPU generation: it reproduces on
E031.38 (Adreno 642L) and E031.41 (Adreno 740) and is fixed by E031.45
(Adreno 619), so the workarounds are gated on the compiler version. Where
they are not needed they cost real throughput - 42.4 -> 35.1 GFLOPS on an
Adreno 840 q6_K GEMV. The explicit compiler-type check is required, not
redundant: newer_than_or_same() is false for every non-E031 compiler, so
negating it alone would enable the workarounds on E17 and DX.
test-backend-ops MUL_MAT is 919/919 on the Adreno 740, 642L, 619, 840 and
850; the 740 and 642L were 909/919 before. The 642L additionally needs the
A6X per-kernel-program support to reach these tests at all.

* CUDA: runtime GGML_CUDA_MMVQ_MAX to tune the mvq->MMQ decode crossover
Add a runtime override of the mul_mat_vec_q -> MMQ batch crossover
(default MMVQ_MAX_BATCH_SIZE). Lowering it routes batches above the
threshold from the CUDA-core vector kernel to the int8 MMQ tensor-core
path, which is faster once quantized decode becomes compute-bound at
B>1 (measured +23-41% at B=8 on RTX 5090 for Q4_K dense, no low-batch loss).
The value is parsed once and clamped to [1, MMVQ_MAX_BATCH_SIZE], since
mul_mat_vec_q asserts ncols_dst <= that; invalid input warns and falls
back to the default. The override is applied consistently in both the
mul_mat_vec_q and MUL_MAT_ID dispatch paths. Default behavior unchanged.
* Added Blackwell specific switch point, to reduce dependence on runtime env var.
* Add per-HW switch point values for DGX Spark and removing runtime env var

* metal: dequantize q8_0 KV to f16 before flash attention
Add a preprocessing pass for GGML_OP_FLASH_ATTN_EXT on the Metal backend:
when the KV cache is quantized (Q8_0 for now), dequantize K and V into a
contiguous F16 scratch buffer and run the existing F16 flash attention
kernels on it, instead of the in-kernel dequantization path.
- new kernel kernel_flash_attn_ext_dequant_to_f16<block_t, QK, deq_t4x4>:
one thread per quant block (K then V), stride-aware so permuted KV is
supported; instantiated for Q8_0 (extending to Q4_0/Q4_1/Q5_0/Q5_1 is
one instantiation + one gate case)
- the gate is type-only: dequantize whenever the KV is quantized,
regardless of head sizes, GQA ratio or n_kv; the attention kernels
themselves are untouched
- the F16 copies live in the op's own scratch allocation
(ggml_metal_op_flash_attn_ext_extra_dequant_f16); the KV pad kernel
reads the dequantized buffers when the path is active
- the FA pipeline getters gain a use_f16_kv flag selecting the existing
f16 kernels and contiguous strides
- ref: https://github.com/ggml-org/llama.cpp/pull/25556
Verification (M2 Ultra):
- test-backend-ops test -o FLASH_ATTN_EXT: 4798/4798 pass, including the
new q8_0 eval cases (decode/prompt, permuted, sinks+ALiBi+softcap,
kv=113 pad path, kv=16384)
- llama-perplexity on Qwen2.5-0.5B with -ctk q8_0 -ctv q8_0 matches the
f16 KV reference (PPL 1.0008 vs 1.0008)

* metal : launch the FA KV dequant kernel separately for K and V
Simplify kernel_flash_attn_ext_dequant_to_f16: it now dequantizes a single
tensor (its own ne/nb and dst) with no is_v branching, and the op dispatches
it twice with the same pipeline - once for K and once for V. The kargs
struct shrinks to a single ne/nb set plus nblocks.
Assisted-by: pi:llama.cpp/Qwen3.8-27B
* metal : dequantize q4_0, q4_1, q5_0 and q5_1 KV to f16 before flash attention
The dequant pass now covers all quantized KV types supported by the Metal
flash attention kernels. The dequant kernel, kargs, scratch allocation and
dispatch are type-generic, so each type is one kernel instantiation plus one
gate case.
Assisted-by: pi:llama.cpp/Qwen3.8-27B
* metal : skip the redundant V dequant when V is a view of K
In MLA-based models, the V of the FA op is a view of K (the first ne20
elements of each K row); the dequantized V is then a view of the dequantized
K, so skip the second dequant dispatch, do not reserve the V scratch region,
and let the pad and attention kernels read V from the K F16 buffer with K's
strides. The detection follows the CUDA backend:
V->view_src && (V->view_src == K || (V->view_src == K->view_src && V->view_offs == K->view_offs))
Also fix the FA pipeline getters: ns10/ns20 are function constants baked into
the kernels and must be the actual K/V row widths as seen by the kernel. The
dispatch now passes them explicitly (nb11_attn/nb10_attn, nb21_attn/nb20_attn)
instead of the getters assuming contiguous F16 KV (ns20 = dv), which was wrong
when V is read from K with K's row pitch (e.g. 576 vs 512).
New test cases: 576/512 q8_0 (MLA shape, V is a view of K) at kv=113 (KV pad),
nb=1 (vec) and nb=64 (non-vec).

* ggml-cpu: gate __fp16 on __ARM_FP16_FORMAT_IEEE
__ARM_NEON only signals NEON availability. The __fp16 type also needs
the IEEE half format, implied on AArch64 but selected with
-mfp16-format=ieee on 32 bit Arm, where the compiler otherwise rejects
the type.
The guard keeps every toolchain that provides the type on the same code
and sends that one configuration to the generic lookup path.
* ggml-cpu: gate the NEON+FMA block on __ARM_FP16_FORMAT_IEEE
Both halves of the F16 section dereference __fp16, so armv7 with
neon-vfpv4 hits the same unknown type error. Without the IEEE
format the configuration now falls back to the scalar path.

* vulkan: tiled transpose for 0<->2 permuted CONT
-ggml_vk_get_cpy_pipeline only routed to the tiled shared-memory transpose
shader when dim1 was the innermost dimension, i.e. ggml_transpose (a 0<->1
swap). A 0<->2 swap -- ggml_cont(ggml_permute(x, 2, 1, 0, 3)) -- fell back to
the generic per-element strided copy, whose source reads stride by ne0*ne1
elements: one cache line per lane.
-DeepSeek-V4's lightning indexer performs exactly that permute on a
[n_kv, n_tokens, n_head] tensor. On Vulkan/RADV gfx1151 it ran at ~1-9 GB/s of
a ~200 GB/s part and accounted for 43% of total prefill time.
-Add copy_transpose_02.comp, mirroring copy_transpose.comp but tiling over dst
dims (0, 2) with dims 1 and 3 as the batch, so reads walk src dim2 and writes
walk dst dim0 -- both contiguous. The selection condition additionally requires
a non-contiguous source and a contiguous destination so it cannot take cases
the contiguous-copy shader already handles.
-test-backend-ops only exercised ggml_transpose for CONT, so the strided path
was untested. Add test_cont_permute covering (2,1,0,3), (1,2,0,3) and (0,2,1,3)
over f32/f16 at tile-aligned, tile-unaligned and large shapes. The large shapes
are in the eval set rather than only in perf because perf mode does not verify
results.
-Measured on gfx1151, ne=[n_kv,64,64,1], perm=(2,1,0,3), f32:
n_kv=1024: 9.08 -> 579.85 GB/s
n_kv=1280: 20.03 -> 153.71 GB/s
n_kv=2048: 7.11 -> 91.68 GB/s
n_kv=2304: 16.24 -> 86.49 GB/s
-The ~2.2x penalty previously seen at power-of-two n_kv (destination-stride
aliasing) is gone. End to end, DeepSeek-V4-Flash IQ3_XXS prefill on a 9k-token
prompt goes from 56.33 t/s to 103.74 t/s (+84%).
-Note: at n_tokens=512 a single slow-path dispatch takes ~273 ms and looping it
in perf mode can trip the GPU watchdog, so the perf cases use n_tokens=64.
* tests: fold test_cont_permute into test_cont, add L2-exceeding perf shapes
Review feedback: test_cont gains a permute parameter ({0,0,0,0} = none),
matching test_mul_mat's pattern, and the separate struct is gone. Perf
adds [n_kv, 512, 64, 1] variants (~0.5 GB per run) that exceed GPU L2,
since the 64-token shapes fit in cache on large parts and read above
memory bandwidth.
* tests: trim perf-case comment to the two-line summary
* vulkan: trim comments on the 0<->2 transpose path
Drop the shader file header, the read/write block comments and the
rationale prose in the CONT test cases. Keep the tile-shape and
bank-conflict notes and the permute parameter documentation.

max_len defaults to 60 in the server, and that only takes effect on the token
timestamps path. Until v1.8.3 token timestamps were limited to verbose_json, so
the default never reached other formats. #3679 removed that condition, which
left every response wrapped at 60 characters, on a token boundary rather than a
word one.
Resolve the default after the other parameters and enable it only for
verbose_json, or when max_len or split_on_word was asked for. Clients passing
max_len with any format still get wrapping.

directory.
The motivation for this is that it is currently in the root of the repo
and is not currently active. Moving it to the workflows directory will
make it active and allow it to run.
This commit removes package.json from git and adds package.json to the
gitignore.
This file is generated by CMake configure and will be updated and
overwritten causing a lot of noise in the git history.
It have also been updated manually as part of our release process which
will not be needed either.

* ci: add GGML_NATIVE=OFF to build-clang.yml
This commit disables native CPU instructions from the ubuntu-22-clang
job.
The motivation for this is that currently it is possible that the
