ggml-cpu : keep the FP16->FP32 lookup table on x86 with F16C (#30342 ) (#30343 )

* ggml-cpu : keep the FP16->FP32 lookup table on x86 with F16C (#30342) #30270 routed both scalar conversions through F16C. For FP16->FP32, Clang 20.1.8 lowers the intrinsic to a vpinsrw merging into the live accumulator register of the quantized dot products, which serialises the loop (19 vs 4 cycles/iteration estimated, 45-65% slower Q8_0/Q4_0 MUL_MAT_ID kernels measured). Keep F16C for FP32->FP16 as intended and the table for FP16->FP32. * ggml-cpu : comment out the F16C FP16->FP32 define instead of removing it (review)

+Downstream applications like `llama-server` can then make informed decisions about special token parsing based on the `is_input` flag. In `libcommon`, `common_chat_templates_apply()` returns these parts as `common_chat_params::prompt` (see `common_chat_prompt` in `common/chat.h`).

 **Caveats:**
 - Special tokens dynamically constructed from user input will not function as intended, as they are treated as user input. For example: `'<|' + message['role'] + '|>'`.

+## MiniCPM-V 4.7
+
+### Prepare models and code
+
+Download [MiniCPM-V-4.7](https://huggingface.co/openbmb/MiniCPM-V-4.7) PyTorch model from huggingface to "MiniCPM-V-4.7" folder.
+
+The model must be the standard `transformers` checkpoint (no `trust_remote_code` for the text and vision graph used here); the architecture in `config.json` is `MiniCPMV4_7ForConditionalGeneration` with a `qwen3_5_text` (or `qwen3_5_moe_text`) text model and a SigLIP-based vision tower plus a window-attention `vit_merger`, same as MiniCPM-V 4.6.
+
+If the checkpoint ships no MTP weights, pass `--no-mtp` to skip the nextn layers.
+
+### Build llama.cpp
+
+If there are differences in usage, please refer to the official build [documentation](https://github.com/ggml-org/llama.cpp/blob/master/docs/build.md)
+
+Clone llama.cpp:
+```bash
+git clone https://github.com/ggml-org/llama.cpp
+cd llama.cpp
+```
+
+Build llama.cpp using `CMake`:
+```bash
+cmake -B build
+cmake --build build --config Release
+```
+
+
+### Usage of MiniCPM-V 4.7
+
+MiniCPM-V 4.7 is converted directly through `convert_hf_to_gguf.py`. The same script is invoked twice on the original Hugging Face directory: once to produce the language-model GGUF and once with `--mmproj` to produce the multimodal projector GGUF.
+
+```bash
+# language model
+python ./convert_hf_to_gguf.py ../MiniCPM-V-4.7 --outfile ../MiniCPM-V-4.7/ggml-model-f16.gguf --no-mtp
+
+# multimodal projector (vision tower + window-attention vit_merger + DownsampleMLP merger)
+python ./convert_hf_to_gguf.py ../MiniCPM-V-4.7 --mmproj --outfile ../MiniCPM-V-4.7/mmproj-model-f16.gguf
+
+# optional: quantize to Q4_K_M
+./build/bin/llama-quantize ../MiniCPM-V-4.7/ggml-model-f16.gguf ../MiniCPM-V-4.7/ggml-model-Q4_K_M.gguf Q4_K_M
+```
+
+The default projector merges 16x (4x4 patches into one token). To keep 4x more visual tokens, copy the model dir and set `"downsample_mode": "4x"` in the copy's `preprocessor_config.json` before running the `--mmproj` conversion; the loader reads `clip.vision.projector.scale_factor` to pick the graph.
+
+
+Inference on Linux or Mac
+```bash
+# run in single-turn mode
+./build/bin/llama-mtmd-cli -m ../MiniCPM-V-4.7/ggml-model-f16.gguf --mmproj ../MiniCPM-V-4.7/mmproj-model-f16.gguf -c 4096 --jinja --image xx.jpg -p "What is in the image?"
+
+# run in conversation mode
+./build/bin/llama-mtmd-cli -m ../MiniCPM-V-4.7/ggml-model-Q4_K_M.gguf --mmproj ../MiniCPM-V-4.7/mmproj-model-f16.gguf --jinja
+```
+
+The chat template enables thinking by default. Pass `--chat-template-kwargs '{"enable_thinking": false}'` to `llama-server` to turn it off.
