KAE Device Passthrough

This section uses the HPRE device as an example to describe how to pass through a KAE device to a container.

To pass through other devices, change the resource name to that of the corresponding device as described in Table 1.

**Table 1** Mapping between KAE devices and KAE device resource names
KAE Device	Device Resource Name
HPRE	kae.kunpeng.com/hisi_hpre
SEC	kae.kunpeng.com/hisi_sec2
ZIP	kae.kunpeng.com/hisi_zip

KAE devices require KAE libraries for normal running. Generally, KAE libraries are not installed in containers. In this example, KAE libraries on the host are mapped to the container. In practice, you can install KAE libraries in the container or map the KAE libraries on the host to the container as required.

Make the declaration in the YAML file of the Pod.

The device to be used is declared by adding kae.kunpeng.com/hisi_hpre: "1" to requests and limits in resources.

        
         
           
           
             apiVersion: v1
kind: Pod
metadata:
  name: kae-test
spec:
  containers:
  - name: kae-test
    image: kae-test:latest
    command: ["/bin/sh", "-c", "while true; do echo hello; sleep 300000; done"]
    imagePullPolicy: IfNotPresent
    resources:
      requests:
        kae.kunpeng.com/hisi_hpre: "1"
      limits:
        kae.kunpeng.com/hisi_hpre: "1"
    volumeMounts:
      - name: local-lib
        mountPath: /usr/local
  volumes:
    - name: local-lib
      hostPath:
        path: /usr/local/  

            

          

        
       

Deploy the Pod.

       
            kubectl apply -f kae-pod/kae-test-pod.yaml

After the deployment is complete, check the Pod status.

       
            kubectl get pod

The command output is as follows. If the Pod status is Running, the installation is successful.

       
            NAME       READY   STATUS    RESTARTS   AGE
kae-test   1/1     Running   0          3h20m

Access the Pod and check whether the KAE device has been mounted.
1 2

kubectl exec -it kae-test bash ls /dev
kae-test indicates the Pod name. Change it to the Pod name you have defined.
If the hisi_hpre-x device exists in the /dev directory, the KAE device has been mounted successfully.
