if I want to use device /dev/mem, I need modify some config files.

host-devices-mem.yaml

apiVersion: v1
kind: ConfigMap
metadata:
  name: host-devices
  namespace: kube-system
data:
  config.json: |
    {
      "resourceName": "github.com/everpeace-mem",
      "socketName": "everpeace-mem.sock",
      "numDevices": 100,
      "hostDevices": [{
        "hostPath": "/dev/mem",
        "containerPath": "/dev/mem",
        "permission": "r"
      }]
    }

host-device-plugin.yaml

  template:
