shalinib-ibm c6980ff29d ggml-cpu: Fix gcc 15 ICE on ppc64le (#20083) (#20130)
This patch addresses an Internal Compiler Error (Segmentation fault)
observed with gcc 15 by replacing the intrinsic + cast by doing
a cat on the data first and then calling the intrinsic. This bypasses the
buggy compiler path while maintaining identical instruction selection.

Performance Verification:
Assembly analysis on RHEL 9 (GCC 15.1.1) confirms that both the original
code and this fix generate the identical Power10 prefixed load instruction:
    `plxv 40, 2(14)`

This ensures zero performance regression while unblocking builds on
newer toolchains.

Reproduced on:
- Alpine Linux + GCC 15.2.0-r2
- RHEL 9  + GCC 15.1.1 (gcc-toolset-15)

Andreas Kieslinger 2cd20b72ed CUDA: Improve performance via less synchronizations between token (#17795)
* Adds CPU-to-CUDA copy capability to
ggml_backend_cuda_cpy_tensor_async()

* Adds function to relax sync requirements between input copies on
supported backends (CUDA for now)

* Exchanges synchronous copy with async copy function.

* Adds macro guards to allow compilation in non-CUDA builds

* Reworked backend detection in ggml-backend.cpp to avoid linking
conflicts

* Relax requirement of checks in async CUDA copies from backend and buffer type to just buffer type, to avoid linking issues

* Minor cleanup

* Makes opt-in to relax use of explicit syncs more general. Backends like
vulkan which require a synchronization between HtoD copies and graph
execution could also adopt this change now.

* Reintroduces stricter check for CPU->CUDA backend async copy via
GGML_DEVICE_TYPE_CPU.

* Corrects initialization of ggml_backend_sync_mode in
ggml_backend_sched_split initialization

* Simplifies synchronizations to adhere to `saaasg` pattern.

* Apply suggestion from @ggerganov (src->buffer to buf_src)

* Apply suggestion from @ggerganov (src->buffer to buf_src) v2

Abhijit Ramesh 49a7564ac1 ggml webgpu: fix workgroup dispatch limit for large batch sizes (#19965)
* ggml-webgpu: fix workgroup dispatch limit for large batch sizes

WebGPU limits workgroup sizes to 65535 per dimension. Large MUL_MAT
operations with batch sizes exceedeing this limi would fail.

* add compute_2d_workgroups() helper to split total workgroup ID across
X/Y dimensions

* update mul_mat_reg_tile.wgsl to reconstruct linear workgroup ID from 2D
   dispatch

* update mul_mat_subgroup_matrix.wgsl to reconstruct linear workgroup ID
  from 2D dispatch

* update mul_mat.wgsl to compute global index from 2D workgroup
  coordinates

* refactor all three mul_mat dispatch paths to use the shared helper

* ggml-webgpu: add bounds checking for over-dispatched workgroups

2D workgroup dispatch can over-dispatch when total workgroups don't
divide evenly into the 65535 per-dimension limit. Extra workgroups
would compute invalid batch indices, causing memory corruption.

* add batch_idx bound check to mul_mat_reg_tile.wgsl and
mul_mat_subgroup_matrix.wgsl to prevent over-dispatched workgroups
from accessing invalid memory

* fixes test failures with large batch sizes (eg., bs=[128, 1024])

* ggml-webgpu: add back TODO for spliting large sizes into batches

* Optimize 2d workgroup provisioning

* Set some parameters that increase speed

Jayant Lohia ecbcb7ea9d CUDA: add CDNA3 MFMA support for flash attention MMA kernel (#19806)
* CUDA: add CDNA3 MFMA support for flash attention MMA kernel

Add MI300X (gfx942) MFMA tensor core flash attention using
v_mfma_f32_16x16x16_f16 (FP16 in, FP32 accumulate).

- Add FATTN_WARP_SIZE=64 for CDNA wavefront64
- Add CDNA config for head sizes 64, 80, 96, 112, 128
- Add FP16 MFMA intrinsic path in mma.cuh
- Add manual V transpose load for MFMA register layout
- Route CDNA to MMA for prompt processing, VEC for token generation
- Fix Q loading and combine stride granularity for non-power-of-2 heads

Benchmarks (Qwen2.5-1.5B Q4_K_M, MI300X):
  pp512  +7%,  pp1024 +13%,  pp2048 +23%,  pp4096 +39%
  tg128  -10% (FA overhead, VEC used for both)

All 2480 flash attention tests pass.

Ref: https://github.com/ggml-org/llama.cpp/issues/17917

* address review: replace FATTN_WARP_SIZE with constexpr, improve dispatch

- Replace #define FATTN_WARP_SIZE with constexpr int warp_size =
  ggml_cuda_get_physical_warp_size() in each device function
- Use ne[1]*gqa_ratio threshold for MMA vs tile dispatch. Benchmarked
  crossover on MI300X @ d32768 with power-of-2 GQA models:
    hsk=64  (Llama 1B, gqa=4): MMA wins at eff >= 128 (+11%)
    hsk=128 (Llama 3B, gqa=4): MMA wins at eff >= 128 (+4%)
  Unified threshold: eff_nq >= 128 for all head sizes.
- Remove VEC fallback; small batches fall through to tile kernel

* Update ggml/src/ggml-cuda/fattn.cu

* use ggml_cuda_info().devices warp_size instead of hardcoded check

Kevin Pouget ffaafde16f ggml-virtgpu: improve the reliability of the code (#19846)
* ggml-virtgpu-backend: validate the consistency of the received objects

This patch adds consistency checks in the
ggml-virtgpu-backend (running on the host side) to ensure that the
data received from the guest is consistent (valid pointers, valid
sizes and offsets).

* ggml-virtgpu-backend: add fallback/skips for optional ggml backend methods

```
  1. bck->iface.synchronize(bck)
  2. buft->iface.get_alloc_size(buft, op)
  3. buft->iface.get_max_size(buft)
```

these three methods are optional in the GGML interface. `get_max_size`
was already properly defaulted, but `backend sychronize` and `butf
get_max_size` would have segfaulted the backend if not implemented.

* ggml-virtgpu-backend: fix log format missing argument

* ggml-virtgpu-backend: improve the abort message

* ggml-virtgpu-backend: more safety checks

* ggml-virtgpu-backend: new error code

* ggml-virtgpu-backend: initialize all the error codes

* ggml-virtgpu: add a missing comment generated by the code generator

* ggml-virtgpu: add the '[virtgpu]' prefix to the device/buffer names

* ggml-virtgpu: apir_device_buffer_from_ptr: improve the error message

* ggml-virtgpu: shared: make it match the latest api_remoting.h of Virglrenderer APIR

(still unmerged)

* ggml-virtgpu: update the code generator to have dispatch_command_name in a host/guest shared file

* ggml-virtgpu: REMOTE_CALL: fail if the backend returns an error

* docs/backend/VirtGPU.md: indicate that the RAM+VRAM size is limed to 64 GB with libkrun

* ggml-virtgpu: turn off clang-format header ordering for some of the files

Compilation breaks when ordered alphabetically.

* ggml-virtgpu: clang-format

* ggml-virtgpu/backend/shared/api_remoting: better comments for the APIR return codes
