## Build/Use BigDL-LLM xpu image

### Build Image
```bash
docker build \
  --build-arg http_proxy=.. \
  --build-arg https_proxy=.. \
  --build-arg no_proxy=.. \
  --rm --no-cache -t intelanalytics/bigdl-llm-xpu:2.5.0-SNAPSHOT .
```


### Use the image for doing xpu inference

To map the `xpu` into the container, you need to specify `--device=/dev/dri` when booting the container.

An example could be:
```bash
#/bin/bash
export DOCKER_IMAGE=intelanalytics/bigdl-llm-xpu:2.5.0-SNAPSHOT

sudo docker run -itd \
        --net=host \
        --device=/dev/dri \
        --memory="32G" \
        --name=CONTAINER_NAME \
        --shm-size="16g" \
        $DOCKER_IMAGE
```


After the container is booted, you could get into the container through `docker exec`.

To verify the device is successfully mapped into the container, run `sycl-ls` to check the result. In a machine with Arc A770, the sampled output is:

```bash
root@arda-arc12:/# sycl-ls
