Hitting error while compiling on windows:

error C3861: 'unsetenv': identifier not found

Reason: unsetenv() is a POSIX function; it doesn’t exist on Windows. Visual Studio (MSVC) won’t recognize it.

Proposed fix: Use _putenv_s() (Windows equivalent)
This is supported by MSVC and achieves the same effect: it removes the environment variable from the process environment.

This keeps cross-platform compatibility.

Georgi Gerganov c7abcd577b graph : remove redundant GDN state transposes (llama/20443)
* ggml : transpose fused GDN state access for coalesced memory reads (llama/20436)

The fused Gated Delta Net kernel accessed the [S_v, S_v] state matrix
column-wise on row-major storage, causing strided reads (stride S_v =
128 floats = 512 bytes) that waste GPU cache bandwidth. This produced a
39% regression on Qwen3.5-9B (Metal, M4 Max) compared to the unfused
path.

Transpose the state indexing so threads read contiguously:
- Metal: s_ptr[is*S_v] -> s_ptr[is] (stride 1 vs S_v)
- CUDA:  curr_state[i*S_v+col] -> curr_state[col*S_v+i] (coalesced)
- CPU:   restructured loops for row-wise transposed access

Also add --fused-gdn [on|off|auto] CLI flag (mirrors --flash-attn) so
users can control fused GDN independently of auto-detection.

All GATED_DELTA_NET backend-ops tests pass.

* ggml : use SIMD dot products in CPU GDN kernel, couple AR/chunked fused flags

- Replace scalar inner loops with ggml_vec_dot_f32 for SIMD-optimized
  dot products in the CPU fused GDN kernel (delta and attention output)
- Couple fused_gdn_ar and fused_gdn_ch flags in auto-detection: if one
  path lacks device support, disable both to prevent state layout mismatch
  between transposed (fused) and non-transposed (unfused) formats

ProgenyAlpha 2450919665 vulkan: add GATED_DELTA_NET op support (llama/20334)
* vulkan: add GATED_DELTA_NET op support

Implements the fused gated delta net recurrence as a Vulkan compute
shader with full support for scalar gate, KDA vector gate, GQA
broadcast, multi-token sequences, and permuted (non-contiguous) q/k
inputs. Specialization constants select head size (32/64/128) and
KDA mode at pipeline creation time.

Passes all 13 test-backend-ops cases on AMD Radeon 890M (RADV GFX1150).

Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

* vulkan: optimize GATED_DELTA_NET shader (Phase 1)

- vec4 dot products on all inner loops (dp4 hardware intrinsic)
- Cache exp(g) in shared memory for KDA path, eliminating ~32K
  redundant global reads and ~16K redundant exp() calls per token
- vec4 fused decay + rank-1 update (3 vec4 ops vs 12 scalar ops)
- Add perf benchmark cases for GATED_DELTA_NET to test-backend-ops

KDA TG: +5.4% throughput. Non-KDA: no regressions.
13/13 test-backend-ops passing on AMD Radeon 890M (RADV GFX1150).

* vulkan: address review feedback for GATED_DELTA_NET

Pipeline array refactor [3][2], A_TYPE/D_TYPE/FLOAT_TYPE shader macros,
scale in push constants, supports_op fix, dispatch restructuring.

Add a fused Metal kernel for the gated delta net recurrence op
(#19504), enabling GPU-accelerated inference for DeltaNet-based
models (Qwen3.5, etc.) on Apple Silicon.

Supports both GDA (scalar gate) and KDA (per-row gate) modes
with head_size 64 and 128. Unsupported configurations (head_size
32, non-contiguous tensors) gracefully fall back to CPU.

Performance: Qwen3.5-0.8B Q4_K_M on M4 Max

* Shard columns across warps

This reduces register pressure (avoids spill for S_v = 128) and gives

* Remove unneded include in gated_delta_net.cu

* Improve comments

* Make sharding HIP-compatible

1. Use ggml_cuda_get_physical_warp_size() to determine warp size flexibly
2. Add test with partial warp to test sum reduction on CUDA

* Remove fastdiv_s64, as we can treat neqk1 and rq3 as uint32_t

* Rename variables

* Enable GDN also for prefill, move TODO for chunked_GDN

* Actually remove the TODO from 206890897546bd16602c3b79394fd5ea09ef199f

* Get warp size at runtime

warp_size is not known at compile time in hip host code.

Richard Davison e4021d4071 ggml : add NVFP4 quantization type support (llama/19769)
* WIP: add NVFP4 quantization support

* tests

* improve NVFP4 dot product implementation performance and fix bad super call

* typo

* Use nvfp4 kvalues

* vulkan : fix NVFP4 shader compilation by including kvalues_mxfp4 lookup table

* vulcal and perf fixes

* wip

* Fix metal

* fix vulcan

* Rename threshold & fix wrong scale

* Fix MOE

* Shelf backend implementations (CUDA, Metal, Vulkan, arch-specific SIMD)

Remove NVFP4 support from GPU backends and architecture-specific
optimized dot products. These should be added in separate PRs so
backend specialists can review them independently.

Reverted files:
- ggml-cuda: common.cuh, convert.cu, mmq.cu/cuh, mmvq.cu, vecdotq.cuh,
  quantize.cu/cuh, mma.cuh, ggml-cuda.cu, fattn-tile.cuh
- ggml-metal: ggml-metal.metal, ggml-metal-device.cpp, ggml-metal-impl.h,
  ggml-metal-ops.cpp
- ggml-vulkan: ggml-vulkan.cpp, all vulkan-shaders/*
- ggml-cpu arch: arm/quants.c, x86/quants.c, powerpc/quants.c, s390/quants.c

Core NVFP4 support (type definition, CPU fallback dot product,
quantization, dequantization, conversion) is retained.

* Fix arch-fallback.h: add NVFP4 generic fallback for all platforms

After shelving backend-specific SIMD implementations, the generic
CPU dot product needs to be aliased on ARM, x86, PowerPC, and s390
platforms that previously relied on arch-specific versions.

* quantize: add NVFP4 as a quantization type option

* Fix ggml_fp32_to_ue4m3: handle subnormal values

Previously, values with ue4m3_exp <= 0 were clamped to 0, causing
all small scales to underflow. This made NVFP4 quantization via
llama-quantize produce garbage (PPL = 5.8M) since typical transformer
weights have amax/6.0 in the range 0.001-0.01, which falls in the
UE4M3 subnormal range.

Now subnormals are properly encoded as man * 2^-9 (exp=0, man=1..7),
matching the decode path in ggml_ue4m3_to_fp32.

Result: NVFP4 requantization now produces PPL = 15.25 (vs F16 = 14.33),
comparable to Q4_1 (PPL = 15.81) at slightly lower BPW (4.70 vs 5.15).

* Restore ARM NEON NVFP4 dot product implementation

Restores the optimized ggml_vec_dot_nvfp4_q8_0 for ARM NEON using
vqtbl1q_s8 lookup and ggml_vdotq_s32 dot products.

tg128 performance: 4.37 t/s (generic) -> 13.66 t/s (NEON) = 3.1x speedup

* Optimize ARM NEON NVFP4 dot product: LUT + vpaddq + vfmaq

- Add ue4m3_scale_lut[128] to ggml-common.h replacing branch-heavy
  ggml_ue4m3_to_fp32() in the hot loop
- Use vpaddq_s32 for pairwise int32 reduction instead of vaddvq_s32
- Accumulate with vfmaq_f32 into float32x4_t vector accumulators

tg128: 8.1 -> 31.0 t/s (3.8x speedup, 77% of Q4_1 speed)

* ARM NEON NVFP4: rearrange q8 to match nibble layout

Alternative approach: rearrange q8 data to match the NVFP4 lo/hi
nibble layout instead of rearranging the looked-up NVFP4 values.
Eliminates vcombine_s8(vget_low, vget_low) shuffles.

Performance is equivalent (~18.5 t/s) - the bottleneck is the 2x
block overhead from QK=16 vs QK=32, not the shuffle instructions.

* CPU only backend 64 super-block layout

* cleanup

* Remove unused LUT

* int

* exclude NVFP4 from unsupported ops in metal build

* remove quantization for now

* store scales as native UE4M3, preserve original model bits when possible

* Update convert_hf_to_gguf.py

Julian Pscheid cabe3d95f4 metal: handle command buffer failures gracefully in synchronize (llama/20306)
Replace GGML_ABORT("fatal error") in ggml_metal_synchronize() with
error flag + return. This aligns synchronize error handling with
graph_compute, which already returns GGML_STATUS_FAILED for the same
condition.

When a command buffer fails (e.g., iOS GPU access revocation during
backgrounding, macOS eGPU disconnect, OOM), the backend enters an
error state instead of killing the host process. Subsequent
graph_compute calls return GGML_STATUS_FAILED immediately. Recovery
requires recreating the backend.

Failed extra command buffers are properly released on the error path
to avoid Metal object leaks.

Paul Flynn ae21974f4f metal : extend mul_mv_ext to BF16, Q2_K, Q3_K (llama/20250)
Enable mul_mv_ext small-batch kernels (BS 2-8) for BF16, Q2_K,
and Q3_K quantization types. These types previously fell through
to the slower single-row mul_mv path.

BF16 uses the float4 dequantize path (like F16). Q2_K and Q3_K
use the float4x4 K-quant path (like Q4_K/Q5_K/Q6_K).
