Release v0.2.2-llamacpp.b6862

[v0.2.2-llamacpp.b6862] - 2025-11-08

Added

• GGML Low-Level Bindings (goggml.go): Direct access to GGML tensor library functions
  • 31 GGML type definitions (F32, F16, Q4_0, Q8_0, BF16, IQ2_XXS, IQ4_XS, etc.)
  • Backend device enumeration and management functions
  • Buffer allocation and memory management
  • Type utility functions (size, quantization checks, name lookups)
  • Quantization helper functions
  • Graceful handling of optional GGML functions (may not be exported in all builds)
  • Helper function tryRegisterLibFunc() for optional function registration
  • Comprehensive test suite (goggml_test.go) with type tests, backend tests, and benchmarks
• Comprehensive GGML Backend API synchronized with ggml-backend.h:
  • Backend Device Functions (8 new): ggml_backend_dev_by_name, ggml_backend_dev_type, ggml_backend_dev_get_props, ggml_backend_dev_backend_reg, ggml_backend_dev_buffer_from_host_ptr, ggml_backend_dev_supports_op, ggml_backend_dev_supports_buft, ggml_backend_dev_offload_op
  • Backend Registry Functions (9 new): ggml_backend_reg_name, ggml_backend_reg_dev_count, ggml_backend_reg_dev_get, ggml_backend_reg_get_proc_address, ggml_backend_register, ggml_backend_device_register, ggml_backend_reg_count, ggml_backend_reg_get, ggml_backend_reg_by_name
  • Backend Buffer Type Functions (4 new): ggml_backend_buft_get_alignment, ggml_backend_buft_get_max_size, ggml_backend_buft_get_alloc_size, ggml_backend_buft_get_device
  • Backend Buffer Functions (6 new): ggml_backend_buffer_init_tensor, ggml_backend_buffer_get_alignment, ggml_backend_buffer_get_max_size, ggml_backend_buffer_get_alloc_size, ggml_backend_buffer_get_usage, ggml_backend_buffer_reset
  • Backend Functions (6 new): ggml_backend_guid, ggml_backend_get_default_buffer_type, ggml_backend_alloc_buffer, ggml_backend_get_alignment, ggml_backend_get_max_size, ggml_backend_get_device
  • New Types: GgmlGuid (16-byte backend identifier), GgmlBackendDevCaps (device capabilities), GgmlBackendDevProps (device properties)
  • Device Type Constants: GGML_BACKEND_DEVICE_TYPE_CPU, GGML_BACKEND_DEVICE_TYPE_GPU, GGML_BACKEND_DEVICE_TYPE_IGPU, GGML_BACKEND_DEVICE_TYPE_ACCEL

Changed

Fixed

• GGML Backend Signatures: Fixed Ggml_backend_load() to accept only one parameter (path) instead of two, matching the actual GGML C API. Function now returns GgmlBackendReg instead of GgmlBackend.
• Function Parameter Validation: Verified all ~50 GGML backend function signatures against official ggml-backend.h to ensure correct parameter types and counts.
