Georgi Gerganov d8e3e2ef08 metal : update sum_rows kernel to support float4 (llama/19524) 2026-02-15 21:44:37 +02:00
Mario Limonciello 39b5f414a3 Add a workaround for compilation with ROCWMMA_FATTN and gfx9 (llama/19461)
There is an upstream problem [1] with AMD's LLVM 22 fork and
rocWMMA 2.2.0 causing compilation issues on devices without
native fp16 support (CDNA devices).

The specialized types aren't resolved properly:
```
/opt/rocm/include/rocwmma/internal/mfma_impl.hpp:2549:37: error: ambiguous partial specializations of 'amdgcn_mfma<__half, __half, __half, 16, 16, 16>'
 2549 |             using ARegsT = typename Impl::ARegsT;
```

Add a workaround to explicitly declare the types and cast when
compiling with HIP and ROCWMMA_FATTN [2].  When this is actually
fixed upstream some guards can be used to detect and wrap the
version that has the fix to only apply when necessary.

hipudding 6a74f56212 CANN: implement quantized MUL_MAT_ID for MoE models (llama/19228)
Implement ggml_cann_mul_mat_id_quant function to support quantized matrix
multiplication for Mixture of Experts (MoE) architectures on CANN backend.

Key features:
- Support Q4_0 and Q8_0 quantized weight formats
- Use IndexSelect to dynamically route expert-specific weights based on indices
- Leverage WeightQuantBatchMatmulV2 for efficient quantized computation
- Handle automatic F16 type conversion for hardware compatibility
- Support both per-expert and broadcast input modes

Implementation details:
- Extract expert weights and scales using CANN IndexSelect operation
- Process each batch and expert combination independently
- Create proper tensor views with correct stride for matmul operations
- Automatic input/output type casting to/from F16 as needed

Testing: All test cases passed for supported types (F32, F16, Q4_0, Q8_0).

Jeff Bolz cea22b3075 vulkan: For coopmat2 FA, use fp16 accumulators for the final result (llama/19376)
The cpu and cuda backends use fp16 for the VKQ accumulator type, this change
does the same for vulkan. This helps particularly with large head sizes which
are very register-limited.

I tried this for the coopmat1 path and it slowed down a bit. I didn't try for
scalar.

I applied the softmax bias that the cuda backend uses to avoid overflow,
although I was not able to reproduce the original bug without it.

Oleksandr Kuvshynov 932def3198 vulkan: fix GPU deduplication logic. (llama/19222)
* vulkan: fix GPU deduplication logic.

As reported in https://github.com/ggml-org/llama.cpp/issues/19221, the
(same uuid, same driver) logic is problematic for windows+intel igpu.

Let's just avoid filtering for MoltenVK which is apple-specific, and
keep the logic the  same as before 88d23ad5 - just dedup based on UUID.

Verified that MacOS + 4xVega still reports 4 GPUs with this version.

Oliver Simons 698265d754 CUDA: Fix loop unrolling for BW in mul_mat_q_stream_k_fixup (llama/19053)
By providing stride_* variables as size_t (i.e., 64-bit) the compiler can
correctly unroll the [two for-loops](557515be1e/ggml/src/ggml-cuda/mmq.cuh (L3789-L3816))
on BW. This gives some perf for prefill/pp phase on BW, while not affecting
other SMs:

Oleksandr Kuvshynov dda7d9cd1c vulkan: handle device dedup on MacOS + Vega II Duo cards (llama/19058)
Deduplication here relied on the fact that vulkan would return unique
UUID for different physical GPUs. It is at the moment not always the case.
On Mac Pro 2019 running Mac OS, with 2 Vega II Duo cards (so, 4 GPU total),
MotlenVK would assign same UUID to pairs of GPUs, unless they
are connected with Infinity Fabric.

See more details here: KhronosGroup/MoltenVK#2683.

The right way is to fix that in MoltenVK, but until it is fixed,
llama.cpp would only recognize 2 of 4 GPUs in such configuration.

The deduplication logic here is changed to only filter GPUs if UUID is
same but driver is different.

    ggml webgpu: fix xielu parameter passing (llama/11)

    The XIELU operation was incorrectly using static_cast to convert
    float parameters to uint32_t, which converted numeric values instead
    of preserving IEEE 754 bit patterns. This caused incorrect values
    to be interpreted by the GPU shader.

    * Use reinterpret_cast to preserve float bit patterns when passing
      through uint32_t params buffer
    * Update WGSL shader parameter types from u32 to f32
    * Re-enable XIELU support (was disabled due to numerical issues)

    Fixes NMSE test failures for XIELU operation on WebGPU backend.

Jeff Bolz b7e323f40b vulkan: Remove transfer_ctx, do everything in compute_ctx. (llama/18945)
* vulkan: Remove transfer_ctx, do everything in compute_ctx.

We had a bug where a set_tensor_async (using transfer_ctx) didn't get
submitted before the graph_compute (using compute_ctx) that came after
it. To avoid this sort of issue, just do everything in compute_ctx.

Remove transfer_cmd_pool, which was already unused.

Jeff Bolz 660d943ff8 vulkan: Use mul_mat_vec_id for small values of n (llama/18918)
Change ggml_vk_mul_mat_vec_id_q_f16 to loop over the batch dimension and
update the indexing calculations in get_offsets.

Mat-vec is faster than mat-mat for small values of n. We don't get the same
reuse of the weights as in the non-ID path, but with this the cost is linear
in n rather than n>1 being far slower than n==1.

Oliver Simons bc09047405 CUDA: Factor out and re-use `block_reduce` function (llama/18785)
* CUDA: Refactor and expose two_stage_warp_reduce_* function

* Use `two_stage_warp_reduce` also in softmax kernel, move smem out of it

Moving smem out of `__device__` function to `__global__` function
allows for explicit smem reuse, as either compiler or cuda rt seem to not
free it afterwards (`cudaFuncSetAttribute` fails when not accounting for
it once for each call to two_stage_warp_reduce)

* Update ggml/src/ggml-cuda/common.cuh

Co-authored-by: Aman Gupta <amangupta052@gmail.com>

* Use two_stage_warp_reduce in group_norm_f32

* Use two_stage_warp_reduce in rms_norm_f32

* Fix smem calculation which expects bytes

* Make `two_stage_warp_reduce` accept all values warp_reduce accepts

Also integrate it into norm_f32 function

* Use two_stage_warp_reduce in l2_norm_f32

* Use type traits for block reduction for better legibility

Also adresss other requests by @am17an such as variable renaming

* Make norm tests cover all cuda paths

* Mark columns % WARP_SIZE !=0 as supported for RMS_NORM_BACK

Unit-tests passed locally, let's see if they pass in the CI as well

* Use `enum class` for `block_reduce_method`

This is more type-safe than plain enum

* Rename variables as suggested in code review by @am17an

* Rename two_stage_warp_reduce -> block_reduce

* Fix trailing whitespace in common.cuh

* Make condition of static_assert type-dependent

This delays evaluation until the template is actually instantiated.
Otherwise, some compilers may evaluate the assert when parsing the
template, resulting in build errors as observed here:

Jeff Bolz aedf332ec5 vulkan: Use VK_EXT_shader_64bit_indexing to handle large mat_mul(_id) (llama/18678)
This fixes incoherent output in Llama-4-Maverick-17B-128E-PAB-Q8_0, which
has a mul_mat_id with an A matrix that's Q8_0 8192 x 5120 x 128.

This should work when the number of blocks in the A matrix is less than 2^32
(for mul_mat_vec or mul_mm_cm2), or for mul_mm I think the limit is like
2^32*LOAD_VEC_A elements.

- Divide batch_stride by QUANT_K earlier, so the block index calculation works in 32b.
- Each vk_pipeline_struct has a linked list of pipelines that will allow it to handle
variants. So far this change just adds a single use case for this, compiling with the
e64BitIndexingEXT flag.
- Use the 64b indexing variant when the A matrix is larger than maxStorageBufferRange.

64-bit indexing has some cost - around 3-5% in MoE models, so it's worth the effort
to avoid enabling it unconditionally.
