This commit enables IQK quantization operations on ARM-based systems,
specifically tested on NVIDIA DGX Spark with GB10 Grace Blackwell.
Changes:
- Enable IQK_IMPLEMENT macro for ARM NEON operations
- Add arm_neon.h header include for ARM SIMD intrinsics
- Fix compilation errors related to missing NEON types and functions
Build requirements for ARM:
cmake .. -DGGML_CUDA=ON \
-DCMAKE_CXX_FLAGS="-march=armv8.2-a+dotprod+fp16" \
-DCMAKE_C_FLAGS="-march=armv8.2-a+dotprod+fp16"
Tested on:
- Platform: NVIDIA DGX Spark (aarch64)
- CPU: GB10 Grace Blackwell Superchip
- Memory: 128GB unified memory
Fixes build errors:
- 'float32x4_t' does not name a type
- 'vld1q_f32' was not declared in this scope
- 'v_expf' was not declared in this scope
- Missing FP16 NEON intrinsics
