TitaniumtownandGeorgi Gerganov 6217ef7468 sycl: parallelize the non-contiguous concat kernel (llama/25852)
* sycl: parallelize the non-contiguous concat kernel

Launch geometry only: the non-contiguous concat kernel launched a single-lane
work-group (1, 1, 1), now it will launch a (1, 1, SYCL_CONCAT_BLOCK_SIZE) one.

SYCL_CONCAT_BLOCK_SIZE is defined in `ggml/src/ggml-sycl/presets.hpp`.

llama-bench (Arc Pro B70, Qwen3.6-27B-UD-Q4_K_XL, -fa on, q8_0 KV),
on top of upstream master: pp2048 920 -> 1006 t/s (+9.4%)

* sycl: cap non-contiguous concat block at ne0

* sycl: make non-contiguous concat block width env-tunable (GGML_SYCL_CONCAT_BLOCK_SIZE)

* Revert "sycl: make non-contiguous concat block width env-tunable (GGML_SYCL_CONCAT_BLOCK_SIZE)"

This reverts commit 2709909e790d298cc0746950caff16ad8ecf9d6f.

97abf5c753 Extended SYCL oneDNN SDPA to non-FP16 KV caches (Q4_0–Q8_0 and FP32) (#25874)
* sycl: extend oneDNN SDPA to Q4_0-Q8_0 and F32 KV caches

Extends the oneDNN SDPA path (PR #25222) to handle non-F16 KV caches by
dequantizing or converting K/V to dense FP16 on-device before feeding
them into the SDPA graph. The fused systolic kernel then runs identically
to the native FP16 path.

Supported KV types:
  - Q4_0, Q4_1, Q5_0, Q5_1, Q8_0: to_fp16_sycl / to_fp16_nc_sycl
  - F32: cont_to_f16_sycl<float>
  - BF16 and IQ types are excluded (no conversion kernel available)

Gate: non-F16 requires K >= 1024 and Q >= 32 (prefill only).
F16 KV runs at any length (existing behavior).

Also includes the stream sync fix (stream->wait_and_throw() unconditional,
PR #25741 by @malsbat) and removal of V_is_K_view aliasing (K and V are
always dequantized to separate buffers).

AgoraPeteandGeorgi Gerganov b5dec64306 ggml: use dynamic allocation for split graph inputs (llama/22789)
* ggml: use dynamic allocation for split graph inputs

Replace fixed-size GGML_SCHED_MAX_SPLIT_INPUTS arrays with dynamically
allocated buffers in the backend scheduler. This fixes crashes when
loading wide MoE models (Gemma 4, Qwen MoE, Mixtral, DeepSeek) on
multi-backend setups where graph splits exceed 30 input tensors.

- split->inputs: dynamic array with grow-on-demand
- sched->graph_inputs: dynamic array with grow-on-demand
- graph_size calculation now uses actual input count instead of fixed constant

Incrementing `ref_count` at the beginning is important later
in the `free()` method of the `ggml_backend_opencl_context` at program end.
If we do not increment the `ref_count`, the result would be -1 here,
and consequently, the profiling data would not be flushed and written.

* SYCL: add oneMKL GEMM flash attention for XMX-accelerated prompt processing

* fattn-mkl: fix interleaved dst layout in normalize kernel

- Fix mkl_fa_normalize_head: use interleaved dst layout
  ((query * n_q_heads + head) * DV) matching TILE's
  flash_attn_combine_results. Previously used dense head-major
  layout which wrote head outputs to wrong addresses, corrupting
  attention for all models except Qwen3.6-27B (where GQA=6 heads
  were sparse enough to avoid visible overlap).

- Remove 7 redundant stream->wait() calls — SYCL in-order queue
  already serializes pure SYCL kernel dependencies. Retain only
  the 4 MKL GEMM ↔ SYCL handshake barriers (oneMKL GEMM uses its
  own internal queue that does not respect SYCL in-order).

- Remove unused dst_row_stride, diagnostic clutter, and dead
  K/V hex dump (fa_diag block in fattn-mkl.cpp).

- Add MKL_FA_DISABLE=1 env var for A/B testing.
- Add FA-DISP watchdog (MKL_FA_DEBUG=1) and FA-DIAG output
  fingerprint (MKL_FA_DIAG=1) in fattn.cpp.

Tested: Gemma-4-26B, Gemma-4-31B, Qwen3.6-27B, Qwen3.6-35B-A3B

* fattn-mkl: enable MKL FA for all KV cache types

Remove the quantized-only restriction on MKL activation — the MKL
kernel converts any non-F16 K/V to F16 via to_fp16_sycl before GEMM,
so F16 (default), BF16, and F32 caches all benefit from XMX hardware
acceleration.  The type restriction was an unnecessary gate.

Before (F16/BF16 default cache + FA on at 32K prefill): ~356 t/s (TILE path)
After:  ~670 t/s (MKL path, matching quantized-cache baseline)

Minimal change: two conditions removed, one comment updated in fattn.cpp.
No kernel or conversion code changes — the dequant pipeline already
covers all types.

* fattn-mkl: rename mkl_disable -> mkl_enable for clarity

* fattn-mkl: refine MKL FA dispatch gates

Three changes:
1. Remove quantized-only restriction - MKL FA activates for all
   KV cache types (F16 default, BF16, F32, quantized).  The MKL
   kernel converts non-F16 K/V via to_fp16_sycl before GEMM.
2. Rename mkl_disable -> mkl_enable to match env var
   (GGML_SYCL_ENABLE_MKL_FA).
3. Replace batch-size threshold with Q->ne[1] >= 32 gate.
   Keeps TG (Q=1) and MTP drafts (Q=3-8) on VEC path where
   fused kernel beats MKL launch overhead.  Routes all
   multi-token prefill through XMX-accelerated GEMM.

Production data confirms Q patterns: 1-8 TG, 32-127 cache reuse,
128+ full reprocess.  At 32K F16/BF16 FA-on: 356 -> 670 t/s.

* ggml-sycl: fix F16 cache + MKL FA multi-turn corruption; add gate guards

Two changes:

1. Always copy F16 K/V to dense row-major buffers before MKL GEMM.
   Previously F16 was read in-place with raw tensor strides. During
   multi-turn conversations, the accumulated KV cache had different
   stride properties than a fresh prefill, producing corrupted outputs.
   Now dense F16 gets a fast memcpy; interleaved (Gemma) gets a strided
   copy kernel. This matches what the quantized paths already did through
   to_fp16_sycl.

2. Gate MKL FA on unsupported op params (max_bias, logit_softcap, batch
   dim mismatch) and pathological F16 strides (nb[1] not a multiple of
   ne[0]*2). These conditions would previously crash inside the MKL
   kernel. Pathological strides (test-only) and ALiBi/softcap fall
   through to TILE/VEC which handle them correctly.

The stride check uses modulo rather than equality, so both dense
(nb1 == ne0*2) and interleaved (nb1 == H * ne0*2) pass — all real
models use these layouts. Only test cases with overlapping rows
(nb1=32 or nb1=75 for ne0=40) are blocked.

Thanks to hmscider for the oneDNN FA PR (#25222) which surfaced the
same insight: always normalize inputs to contiguous F16 before GEMM.

* fattn-mkl: fix quant+GQA KV strides, tighten MKL gate, add K>=1024 tests

Adding K>=1024 flash-attn test cases surfaced several MKL bugs:

- Quant K/V with a padded seq-view (real KV cache) used the wrong
  strides in the dequant path... only the true Gemma interleave
  layout should reconstruct strides. nb[2] vs ne[1]*nb[1]
- Gate was firing on shapes the kernel doesn't handle: head_dim < 64
  or not a multiple of 64, MHA, attention sinks, and
  bf16 decode... fell through to vec which no bf16 case.

Gate MKL to the validated envelope: gqa>=2, head_dim 64 through 512
(has to be a multiple of 64) with matching K/V head size, mask,
no sinks/alibi/softcap... everything else falls back to tile.
Covers Qwen Dense/MoE and Gemma4 Dense/MoE

Ran test-backend-ops -o FLASH_ATTN_EXT: 3641/3641 pass.
Perplexity unchanged... 6.7267 MKL vs 6.7290 stock using
Qwen 27b q5_k_xl

This commit adds the cmake option GGML_NATIVE=OFF to the build-vad

* cuda: Don't crash when querying memory on device with no free memory. (llama/25157)

If a Cuda device has no or limited available memory, the actual call
to cudaMemGetInfo() itself can cause a fatal crash due to a cuda out
of memory error (there is not enough memory to actually query memory)

This causes an issue because we query memory for all devices at
startup even if the user isn't trying to use the device for inference.

Fix this by making the error non-fatal and assigning zero total/free
memory to the device. This will have the downstream effect of the fit
algorithm not trying to put any layers on it, which is desired outcome
vs hard crashing.

this also prevents crashes in cuda enabled builds when user explicitly
passes '-dev none'

* vulkan: Use native e2m1 and e4m3 conversions for mxfp4/nvfp4 (llama/25338)

This uses the new VK_EXT_shader_ocp_microscaling_types extension to do fp4 type
promotions, and also uses the float8 extension to do ue4m3 promotions for
nvfp4. It's reasonable to assume that an implementation that supports fp4 will
also support fp8, so we don't need to handle all possible combinations of
support.

* hexagon: fix hmx-queue signal enum-narrowing problem (llama/25677)

* opencl: avoid the vec path in GEMV for unaligned row stride (llama/25671)

The f16 GEMV kernels take a vectorized path for ne00 >= 128 that casts the row
pointers to half4 or float4. When the row stride is not aligned, the wide load
becomes misaligned. On devices that require natural alignment for vector loads,
the kernel reads garbage. This is the case Intel GPUs and the kernels produce
incorrect results there. Adreno happpens to be byte addressable and the kernels
happen to work.

* metal: fuse snake activation (mul, sin, sqr, mul, add)

Mirror the CUDA, Vulkan and CPU snake fusion: same matcher on the naive
5-op chain, same F32 contract on a and inv_b, same F32/F16/BF16 kernel
with F32 compute. Follows the Metal backend idioms: bf16 instantiation
gated behind GGML_METAL_HAS_BF16 and concurrency ranges checked on the
remaining chain nodes before encoding, as done by the bin fusion.

Covered by the existing backend-agnostic SNAKE_FUSE tests.

* metal: absorb snake fusion into ggml_metal_op_bin

Extract the matcher to ggml_metal_op_can_fuse_snake, mirroring the
Vulkan naming, and dispatch the fused path from ggml_metal_op_bin.
The encode loop switch is back to a single call per case.

* CUDA: dedup MoE gate/up activation quantization (llama/25441)

* CUDA: dedup MoE gate/up activation quantization (fp4)

For MoE gate/up projections the src1 activation is broadcast across the
routed experts (ne11 == 1), so ids_src1 maps every one of a token's
n_expert_used slots to the same physical row. The MMQ path therefore
re-quantized each token's activation n_expert_used times.

For fp4 (NVFP4/MXFP4) src0, quantize each unique token row once instead of
once per expert. For NVFP4 a single quantize+scatter kernel
(quantize_scatter_mmq_nvfp4) quantizes each token once and writes the
resulting block_fp4_mmq straight to all n_expert_used slots, using an
inverse token->compact-row map (build_tok2c). MXFP4, and
GGML_CUDA_MOE_QUANT_GATHER=1, use a two-kernel variant: quantize unique
rows then gather into the expert-sorted layout (gather_mmq_fp4_blocks).
Both are bit-identical to the previous gather-then-quantize path (identical
source data, deterministic per-block quantization), verified by
test-backend-ops MUL_MAT_ID (type_a=nvfp4, broadcast b=1; 790/790 for the
default, gather, and per-expert paths) and by coherent end-to-end
generation. Set GGML_CUDA_NO_MOE_QUANT_DEDUP=1 to force the original
per-expert path.

Same-binary A/B on RTX 5090 (sm_120), Qwen3.6-35B-A3B-NVFP4 prefill @8192
(nsys, graphs-off; the unchanged mul_mat_q GEMM confirms stable clocks):
activation-quant GPU-busy drops 61% (78.2 -> 30.4 ms) with the fused
quantize+scatter, vs 33% (78.2 -> 52.8 ms) for the two-kernel gather. The
fused path avoids materializing and re-reading the 8x compact buffer,
writing the expert copies directly from registers.

* CUDA: bounds-check token ids in build_tok2c_kernel

Guard against malformed ids_src1: skip out-of-range token ids (t < 0 or
t >= n_tokens) and drop entries beyond n_expert_used per token instead of
writing past the token's tok2c region. No behavior change for valid MoE
routing data; test-backend-ops MUL_MAT_ID 790/790.

* Refactor the code based on review comments

* ggml-cuda : restore prop.integrated on HIP builds (llama/24233)

PR #16308 set info.devices[id].integrated = false unconditionally for all
CUDA/HIP devices as a workaround for corrupted output on Jetson Orin
(#15034). On HIP/ROCm the device's real hipDeviceProp_t.integrated flag is
needed: with the cached field forced to false, supports_buft() refuses
CUDA host buffers on AMD APU/UMA parts, while get_type() already reads
prop.integrated (#23007) — an inconsistency that breaks integrated-GPU
host-buffer use on ROCm.

Guard the workaround so it only applies to non-HIP (CUDA) builds and
restore prop.integrated for HIP, keeping the Jetson workaround intact for
CUDA.

Fixes #23977

on SME(v1)-only hardware.

We introduce build-time and runtime distinction between SME and SME2, and

* hexagon: add CLAMP op (llama/25934)

* CUDA: vectorize same-type get_rows with int4 copy (llama/25929)

k_get_rows_float did a scalar one-element-per-thread copy and recomputed the
row-invariant work (index load, fast_div_modulo, src/dst row pointers) for
every element. Hoist that out of the per-element loop, and add a vectorized
path (k_get_rows_float_vec) that copies one int4 (16 B) per thread for the
contiguous same-type (no-cast) case.

The vectorized path is gated at compile time (is_same<src0_t, dst_t>) and at
runtime on 16-byte alignment of the base pointers and all row strides and on
ne00 % VEC == 0. Vectorizing divides the block count by VEC, so a small
single-row gather can drop below the device CU count and regress; an
occupancy gate keeps those on the block-rich scalar path.

On Strix Halo (gfx1151) the DeltaNet recurrent-state gather (ne00=524288)
drops 18.6us -> 13.0us (rocprofv3 HW timestamps), faster than the Vulkan
backend, with no regression on the small conv-state gather; total get_rows
-27%. test-backend-ops GET_ROWS passes (47/47).

* hexagon: check tensor type when reusing descriptors (llama/25968)

* cuda: GET_ROWS quants (llama/25962)

* cuda: add k-quant support to GET_ROWS

Device-side embedding lookups require GET_ROWS to handle the k-quants
used by common GGUF recipes (Q4_K_M stores token_embd as q6_K). Without
it the backend rejects the op and the scheduler falls back to the host,
copying the full embedding matrix back on every token in single-device
graphs.

Factor the super-block dequantizers out of the dequantize_block kernels
in convert.cu into shared device functions in dequantize.cuh and reuse
them from a new k_get_rows_kq kernel : one thread block dequantizes one
(dst row, super-block) pair with the existing thread layouts, 32 threads
for q4_K and 64 for the other k-quants.

Covers q2_K to q6_K in get_rows_cuda and supports_op. i-quants are left
as a TODO.

* cuda: add i-quant support to GET_ROWS

Extends the shared super-block dequantizers to the nine i-quants and
reuses them from k_get_rows_kq with the 32-thread layout of the matching
convert.cu kernels. supports_op gates the k-quant and i-quant path on
ne0 being a multiple of QK_K, which iq4_nl does not guarantee on its
own (QK4_NL sub-blocks). mxfp4 is left as a TODO.

* cuda: add mxfp4 support to GET_ROWS

Moves the mxfp4 dequantizer into the shared super-block helpers and
reuses it from k_get_rows_kq with the 32-thread layout of the matching
convert.cu kernel. mxfp4 joins the ne0 % QK_K gate in supports_op since
its 32-value sub-blocks do not guarantee QK_K-aligned rows on their own.
This closes GET_ROWS type coverage on CUDA: every quantized GGML type
now takes the direct device path.

* cuda: gate the GET_ROWS row size only for 32-value sub-block types

Address review from @pwilkin: the i-quant commit replaced the return
shared by the whole supported type cascade, so f16/f32/bf16/i32 and the
legacy quants also inherited the ne0 % QK_K == 0 gate and any row size
that is not a multiple of 256 fell back to the scheduler. Split the
cascade: unconditional support is restored everywhere, the gate stays
only on iq4_nl and mxfp4 whose 32-value sub-blocks do not guarantee the
QK_K super-blocks the kernel iterates on.

* sycl: fix use-after-return of the SDPA scale in the oneDNN flash-attention path (llama/25880)

* sycl: fix use-after-return of the SDPA scale in the oneDNN flash-attention path

The scale was uploaded with an async memcpy sourced from a stack local. On the
in-order queue that copy is ordered behind the K/V staging kernels; once n_kv is
large enough (>= ~26k observed on Arc Pro B70) the staging outlives the host
stack frame and the copy reads recycled memory, feeding the SDPA a garbage scale.
Output then collapses to a single repeated token and the KV cache is poisoned
for the rest of the session.

Short contexts win the race by accident, and test-backend-ops caps
FLASH_ATTN_EXT at kv=1024, which is why CI never caught it. The previous
device_count > 1 wait_and_throw() gate (and reverting it, PR #25741) fixes the
symptom only by keeping the frame alive across the copy at the cost of a host
sync on every FA call.

Fix: cache one device scalar per (device, value) -- the scale is constant per
model -- and upload it synchronously once. The single-device fast path (no
per-call host sync) is then safe: every device-side hazard already serializes
on the in-order queue. The multi-GPU conservative wait is kept unchanged.

Also:
- GGML_SYCL_FA_ONEDNN_MAX_KV env (0 = unlimited): optional n_kv ceiling that
  routes very long sequences to the native FA kernel.
- test-backend-ops: FLASH_ATTN_EXT F16 cases up to kv=65536 (Qwen3.6-27B
  geometry hsk=hsv=256 GQA 6, and hsk=128 GQA 4), closing the kv=1024 blind
  spot. Note the race itself needs a live multi-op pipeline to reproduce;
  single-op runs pass even on broken builds.

Verified on Arc Pro B70 (bmg_g31), Qwen3.6-27B Q4_K, -c 131072: output
byte-identical at temp 0 to the native FA path through 32k-deep prefill, with
prefill depth-flat at 820-840 t/s (vs 340-350 native at 32k depth).

* sycl: handle GGML_SYCL_FA_ONEDNN_MAX_KV like the other runtime env vars and document it

Review feedback on #25880:
- read the variable once at backend init into g_ggml_sycl_fa_onednn_max_kv via
  ggml_sycl_get_env, and print it in the startup env listing (-lv 4 shows it)
- document GGML_SYCL_FA_ONEDNN and GGML_SYCL_FA_ONEDNN_MAX_KV in the SYCL.md
  runtime table

Also trim the added FLASH_ATTN_EXT cases to kv={4096,16384}: the 32768/65536
shapes exceed the legacy NMSE threshold on both the oneDNN and native kernels
(long-sequence fp16 accumulation drift, present before this PR) and would fail
CI for an unrelated reason.

* sycl: write the SDPA scale from a kernel instead of caching it

The per-(device, value) scale cache was a function-local static
unordered_map with no synchronization, so concurrent backend instances
could access and rehash it at the same time.

Write the scalar with a single_task instead. The value is captured into
the command, so no host memory has to outlive the call -- which is what
the use-after-return fix needed in the first place. That removes the
shared container, the leaked device allocation and the string key, and
it also closes the remaining async-memcpy-from-a-stack-local on the
first flash-attention call.

Ordering does not rely on timing: the queue is created with
sycl::property::queue::in_order and the dnnl stream wraps that same
queue, so the write completes before the SDPA reads the scalar. The
multi-GPU wait_and_throw() branch is unchanged.

Also drop the <cstdlib> include, which is unused.

receives no ne03/ne13/nb03/nb13 arguments. With the unified KV cache,
multi-sequence batches (e.g. llama-perplexity with its default -b 2048,
n_seq=4, or a multi-slot llama-server) present KQ/KQV as 4D tensors with
ne3 = n_stream, so every stream past the first reads the first stream's
K/V and produces garbage. Flash attention masks the bug where it is
enabled; devices where FA is declined (e.g. Adreno 740) hit it with
default settings.

Route ne03/ne13 > 1 to the general path, which handles dim 3, and honor
view_offs when creating the sub-buffers (currently always 0 for tensors
reaching this function, but the function would silently misread any
future view).

* ggml-cuda : disable MMQ on devices with less than 48 KiB shared memory (llama/26141)

ggml_cuda_should_use_mmq() selects MMQ purely from the quantization
type. The current MMQ configurations are designed and maintained against
a minimum of 48 KiB per-block shared memory, the limit provided by
NVIDIA Pascal GPUs and later. On devices that report less, no supported
MMQ tile fits and mul_mat_q_switch_J() aborts when every tile size
exceeds the device's per-block shared memory budget.

Disable MMQ when smpbo < 48 KiB so the caller falls back to the BLAS
path instead of hitting GGML_ABORT. Some current MUSA QY1 devices
report only 28 KiB and are covered by this guard.

Reproduced on a Moore Threads MTT S70 (arch mp_21, 28 KiB shared memory
per block) with an RWKV-7 0.1B Q8_0 model:

  $ llama-bench -m rwkv7-g1d-0.1b-Q8_0.gguf -p 128 -n 0
  J_best=0
  ggml/src/ggml-cuda/template-instances/../mmq.cuh:1521: fatal error
  (core dumped)

Only prefill (batch > 1) is affected; token generation is fine. After
the fix the same device falls back to the BLAS path:

  Q8_0    pp128 1470.7 t/s, tg8 55.3 t/s   (was: abort)
  FP16    unchanged
  Q4_K_M  unchanged

This matches a -DGGML_CUDA_FORCE_CUBLAS=ON build (pp128 1464.2 t/s),
which confirms the fallback path is the one being taken.

This is not MUSA-specific: any device with less than 48 KiB per-block
shared memory is affected.

CappuccinoandGitHub 080bbbe852 examples : Remove leading space from txt output (#3921)
* Fix #587: Remove leading space from txt output

The BPE tokenizer used by Whisper produces tokens with leading spaces,
causing each line in the txt output to start with an unwanted space.

This fix strips leading whitespace (spaces and tabs) from each segment
when writing to txt output files, improving the readability of the
transcription output.

cc7a521508 ggml-hip: enable -funsafe-math-optimizations (llama/24668)
CUDA is compiled with fast math and AMD/HIP is not — this flag lets AMD use fast math too.

We can't use -ffast-math: it implies -ffinite-math-only, which won't compile (ggml uses INFINITY for masking) and produces NaNs. -funsafe-math-optimizations gives the speedup without the NaN problems.

PascalandGeorgi Gerganov 1b0b078a98 cuda: align snake fusion matcher with the other backends (llama/25460)
* cuda: fix snake fusion type predicate, a and inv_b are F32

The matcher required a->type == x->type while launch_snake reads both
as const float *, matching the CPU and Metal contract where a and inv_b
stay F32. F16/BF16 chains never fused and fell back to the naive path,
and a hypothetical all F16 chain would have read F16 bits as float.
Aligns the predicate and the comment with ggml-cpu.c

* cuda: reject snake fusion on non-contiguous operands

The kernel reads x[idx] and a[c] / inv_b[c] linearly, so a
non-contiguous view passing the matcher would silently read wrong data.
Mirror the contiguity guard already present in the CPU, Vulkan and
Metal matchers.

8e7b672fb4 opencl: Q6_K GEMM/GEMV fix for ne01 of weights that are not multiples of 128. (llama/25464)
* opencl: fix garbled output for Q6_K weights with ne01 % 128 != 0 on Adreno

Observed with granite-3.1-3b-a800m-instruct, whose vocab is an odd number.

Route Q6_K dense mul_mat with ne01 % 128 != 0 off the noshuffle path:
decode (ne1==1) uses the correct flat GEMV and the matching GEMM (ne1>1)
falls back to CPU (the flat convert has no verified small-batch GEMM kernel
for these shapes). All standard hidden/FFN/vocab dims are multiples of 128
and keep the noshuffle path.

* opencl: reserve alignment slack for the SOA subbuffer carve in alloc size

set_tensor carves quantized weights into per-component subbuffers (d/q,
ql/qh/s/d, ...) whose origins are each rounded up to the device base
address alignment. When a component's size is not a multiple of the
alignment, the carve extends past ggml_nbytes(tensor) and the last
subbuffer overlaps the next tensor in the pool -- e.g. q6_K [1536, 49155]:
size_s = 49155*96 ends 32 bytes past a 128-byte boundary, so the d
subbuffer ends 96 bytes past the tensor's allocation, and whichever of the
two neighboring tensors is uploaded last silently corrupts the other (here:
the last vocab rows' block scales). This affects any quant type whose
component sizes can be misaligned, on any shape with ne01 not a multiple of
the alignment granularity; standard power-of-two dims are unaffected.

Implement get_alloc_size for the OpenCL buffer type and reserve the
worst-case carve slack (4 aligned gaps; 5 components max, q5_K) for
quantized tensors. Costs at most 512 bytes per quantized tensor at the
observed 128-byte alignment.

* opencl: use lm based q6_k mm when ne1 is not multiple of 128

5f052fbfaf opencl: ragged-tile MoE prefill FP16 GEMM optimization (skip padded expert tiles) (llama/25433)
* opencl: ragged-tile MoE prefill GEMM (skip padded expert tiles)

The MoE prefill GEMM groups tokens into TILESIZE_N=32 per-expert tiles; at low
tokens-per-expert most tiles are mostly padding. When a tile's upper 16 slots
are all padding (router index 0xFFFFFFFF), skip the second dotx16_reduce8 half.
Numerically identical (skipped lanes are padding). Applied to all eight *_f32_ns
MoE GEMMs; default on, opt out with GGML_OPENCL_MOE_RAGGED_FP16=0.

* opencl: quarter-granularity ragged MoE tile-skip (8-col skip-groups)

Replace the two half-tile dotx16_reduce8 calls in the 8 *_f32_ns MoE GEMMs with
four dotx8_reduce4 (8-column) calls, skipping each empty trailing skip-group
independently. Padding is always trailing, so the kernel rounds the valid count
up to the skip granularity and skips fully-padding groups. Byte-identical to the
non-skipped path. New env GGML_OPENCL_MOE_RAGGED_GRAN={8,16,32} (quarter/half/
off); default quarter.

* opencl: move ragged moe env var in cl_init
