- NotifyRegistrationStatus is called against socket to indicate registration result.

During plugin initialization phase, Kubelet will issue Plugin specific calls
(e.g: DevicePlugin::GetDevicePluginOptions).

Once Kubelet determines that it is ready to use your plugin it will issue a
Registration.NotifyRegistrationStatus gRPC call.

If the plugin removes its socket from the PluginDir this will be interpreted

		klog.ErrorS(err, "Client unable to register to kubelet")
		return err
	}
	klog.InfoS("Device Plugin registered with the Kubelet")
	return err
}

// GetDevicePluginOptions returns DevicePluginOptions settings for the device plugin.
func (m *Stub) GetDevicePluginOptions(ctx context.Context, e *pluginapi.Empty) (*pluginapi.DevicePluginOptions, error) {
	options := &pluginapi.DevicePluginOptions{

// This is done as part of device plugin registration.
func (m *ManagerImpl) PluginConnected(resourceName string, p plugin.DevicePlugin) error {
	options, err := p.API().GetDevicePluginOptions(context.Background(), &pluginapi.Empty{})
	if err != nil {
		return fmt.Errorf("failed to get device plugin options: %v", err)
	}

	e := newEndpointImpl(p)
