ggml-metal: add chunked SSD MMA for Mamba-2 prefill optimization (#26647)
* metal: WIP chunked SSD SSM_SCAN kernels for multi-token prefill

* metal: drop scalar SSD path; MMA + sequential tail

* drop WIP ssm scan test noise

* remove state_from_dst and rename CS and NSG constants

* remove unrelated  added whitespace padding

* added clarity to mma_tokens calculation

* added clarity to use_mma bool checks

* added comments to metal ssd op constants for clarity

* reserve K tokens for sequential kernel rollback snapshots

* reset concurrency between mma and seq tail

* remove print args no longer used

* fixed comment to no longer point to specific line

* add FC_SSM_SCAN so seq path skips token offlset unless it's mma tail

* added changes to new ssm.metal for rebase after ggml-metal.metal refactor

* specialize ssm_scan tail with a template instead of a function constant

Quick start

A few options to get llama.cpp installed on your machine:

Once installed:

# Download and run a model directly from Hugging Face
llama cli -hf ggml-org/Qwen3.5-0.8B-GGUF

# Launch OpenAI-compatible API server
llama serve -hf ggml-org/Qwen3.5-0.8B-GGUF
VLM session with `llama cli` VLM session with llama cli Built-in web UI against `llama serve` running Qwen 3.6 Built-in web UI against llama serve

Description

The main goal of llama.cpp is to enable LLM (and VLM) inference with minimal setup and state-of-the-art performance on a wide range of hardware - locally and in the cloud.

  • Plain C/C++ implementation without any dependencies
  • Apple silicon is a first-class citizen - optimized via ARM NEON, Accelerate and Metal frameworks
  • AVX, AVX2, AVX512 and AMX support for x86 architectures
  • RVV, ZVFH, ZFH, ZICBOP and ZIHINTPAUSE support for RISC-V architectures
  • 1.5-bit, 2-bit, 3-bit, 4-bit, 5-bit, 6-bit, and 8-bit integer quantization for faster inference and reduced memory use
  • Custom CUDA kernels for running LLMs on NVIDIA GPUs (support for AMD GPUs via HIP and Moore Threads GPUs via MUSA)
  • Vulkan and SYCL backend support
  • CPU+GPU hybrid inference to partially accelerate models larger than the total VRAM capacity

The llama.cpp project is build on top of the ggml library.
