[V1][Core] Add support for V1 Engine (#295) ### What this PR does / why we need it? Add support for V1 Engine. Please note that this is just the initial version, and there may be some places need to be fixed or optimized in the future, feel free to leave some comments to us. ### Does this PR introduce _any_ user-facing change? To use V1 Engine on NPU device, you need to set the env variable shown below: ```bash export VLLM_USE_V1=1 export VLLM_WORKER_MULTIPROC_METHOD=spawn ``` If you are using vllm for offline inferencing, you must add a `__main__` guard like: ```bash if __name__ == '__main__': llm = vllm.LLM(...) ``` Find more details [here](https://docs.vllm.ai/en/latest/getting_started/troubleshooting.html#python-multiprocessing). ### How was this patch tested? I have tested the online serving with `Qwen2.5-7B-Instruct` using this command: ```bash vllm serve Qwen/Qwen2.5-7B-Instruct --max_model_len 26240 ``` Query the model with input prompts: ```bash curl http://localhost:8000/v1/completions \ -H "Content-Type: application/json" \ -d '{ "model": "Qwen/Qwen2.5-7B-Instruct", "prompt": "The future of AI is", "max_tokens": 7, "temperature": 0 }' ``` --------- Signed-off-by: shen-shanshan <467638484@qq.com> Co-authored-by: didongli182 <didongli@huawei.com>
