Intel QAT device plugin is Kubernetes device plugin for discovering and advertising QAT virtual functions (VFs) in a Kubernetes host. it supports a platform that pairs the Intel®
C62x Chipset (also known as Platform Controller Hub, or PCH) with Intel® Xeon®Processor D Family System-on-a Chip (SoC) or Intel Atom® C3000 Processor Product
Family SoC.

To automatically deploy QAT device plugin in ICN, KuD addon QAT device plugin includes:

Installation script:

(1) Install and probe QAT kernel driver (e.g. intel_qat.ko, qat_c62x.ko, qat_d15xx.ko, qat_c3xxx.ko etc.)

...

Use QAT device plugin in ICN

(1) Create docker image crypto-perf:devel based on instructions in https://github.com/intel/intel-device-plugins-for-kubernetes/blob/master/cmd/qat_plugin/README.md

(2) Create test_qat.yaml with below contents:

kind: Pod
apiVersion: v1
metadata:
    name: qat_pod
spec:
    containers:
    - name: dpdkcontainer
      image: crypto-perf:devel
      imagePullPolicy: IfNotPresent
      command: [ "/bin/bash", "-c", "--" ]
      args: [ "while true; do sleep 300000; done;" ]
      volumeMounts:
      - mountPath: /dev/hugepages
        name: hugepage
      resources:
          requests:
              cpu: "3"
              memory: "1Gi"
              qat.intel.com/generic: '2'
              hugepages-2Mi: "1Gi"
          limits:
              cpu: "3"
              memory: "1Gi"
              qat.intel.com/generic: '2'
              hugepages-2Mi: "1Gi"
     securityContext:
         capabilities:
            add:
                 ["IPC_LOCK"]
volumes:
- name: hugepage
  emptyDir:
     medium: HugePages

(3) Create pod to consume QAT devices

cat test_qat.yaml  | kubectl apply -f -

(4) Verify QAT workload in created Pod

kubectl exec -it qat_pod bash

./dpdk-test-crypto-perf -l 6-7 -w $QAT1 -- --ptest throughput --devtype crypto_qat --optype cipher-only --cipher-algo aes-cbc --cipher-op encrypt --cipher-key-sz 16 --total-ops 10000000 --burst-sz 32 --buffer-sz 64

The output is similar as below:
