## About

This repository contains a framework for developing plugins for the Kubernetes
[device plugins framework](https://kubernetes.io/docs/concepts/extend-kubernetes/compute-storage-net/device-plugins/),
along with a number of device plugin implementations utilising that framework.

## Prerequisites

Prerequisites for building and running these device plugins include:

- Appropriate hardware
- A fully configured [Kubernetes cluster]
- A working [Go environment], of at least version v1.13.

## Plugins

The below sections detail existing plugins developed using the framework.

### GPU device plugin

The [GPU device plugin](cmd/gpu_plugin/README.md) supports Intel
[GVT-d](https://github.com/intel/gvt-linux/wiki/GVTd_Setup_Guide) device passthrough
and acceleration using GPUs of the following hardware families:

- Integrated GPUs within Intel Core processors
- Intel Xeon processors
- Intel Visual Compute Accelerator (Intel VCA)

The demo subdirectory contains both a [GPU plugin demo video](demo#intel-gpu-device-plugin-demo-video)
as well as code for an OpenCL [FFT demo](demo/ubuntu-demo-opencl).

### FPGA device plugin

The [FPGA device plugin](cmd/fpga_plugin/README.md) supports FPGA passthrough for
the following hardware:

- Intel Arria 10
- Intel Stratix 10

The FPGA plugin comes as three parts.

- the [device plugin](#device-plugin)
- the [admissing controller](#admission-controller)
- the [CRIO-O prestart hook](#cri-o-prestart-hook)

Refer to each individual sub-components documentation for more details. Brief overviews
of the sub-components are below.

The demo subdirectory contains a [video](demo#intel-fpga-device-plugin-demo-video) showing deployment
and use of the FPGA plugin. Sources relating to the demo can be found in the
[opae-nlb-demo](demo/opae-nlb-demo) subdirectory.

#### device plugin

The [FPGA device plugin](cmd/fpga_plugin/README.md) is responsible for discovering and reporting FPGA
devices to `kubelet`.

#### admission controller

The [FPGA admission controller webhook](cmd/fpga_admissionwebhook/README.md) is responsible for performing
mapping from user-friendly function IDs to the Interface ID and Bitstream ID that are required for FPGA
programming.  It also implements access control by namespacing FPGA configuration information.

#### CRI-O prestart hook

The [FPGA prestart CRI-O hook](cmd/fpga_crihook/README.md) performs discovery of the requested FPGA
function bitstream and programs FPGA devices based on the environment variables in the workload
description.

### [QAT](https://01.org/intel-quick-assist-technology) device plugin

The [QAT plugin](cmd/qat_plugin/README.md) supports device plugin for Intel QAT adapters, and includes
code [showing deployment](cmd/qat_plugin/dpdkdrv) via [DPDK](https://doc.dpdk.org/guides/cryptodevs/qat.html).

The demo subdirectory includes details of both a
[QAT DPDK demo](demo#intel-quickassist-technology-device-plugin-with-dpdk-demo-video)
and a [QAT OpenSSL demo](demo#intel-quickassist-technology-device-plugin-openssl-demo-video).
Source for the OpenSSL demo can be found in the [relevant subdirectory](demo/openssl-qat-engine).

Details for integrating the QAT device plugin into [Kata Containers](https://katacontainers.io/)
can be found in the
[Kata Containers documentation repository](https://github.com/kata-containers/documentation/blob/master/use-cases/using-Intel-QAT-and-kata.md).

### VPU device plugin

The [VPU device plugin](cmd/vpu_plugin/README.md) supports Intel VCAC-A card
(https://www.intel.com/content/dam/www/public/us/en/documents/datasheets/media-analytics-vcac-a-accelerator-card-by-celestica-datasheet.pdf)
the card has:
- 1 Intel Core i3-7100U processor
- 12 MyriadX VPUs
- 8GB DDR4 memory

The demo subdirectory includes details of a OpenVINO deployment and use of the VPU plugin.
Sources can be found in [openvino-demo](demo/ubuntu-demo-openvino)

## Demos

The [demo subdirectory](demo/readme.md) contains a number of demonstrations for a variety of the
available plugins.

## Developers

For information on how to develop a new plugin using the framework, see the
[Developers Guide](DEVEL.md) and the code in the
[device plugins pkg directory](pkg/deviceplugin).

## Running E2E tests

Currently the E2E tests require having a Kubernetes cluster already configured
on the nodes with the hardware required by the device plugins. Also all the
container images with the executables under test must be available in the
cluster. Given these two conditions are satisfied one can run the tests with

```bash
$ go test -v ./test/e2e/...
```

In case you want to run only certain tests, e.g. QAT ones, then run

```bash
$ go test -v ./test/e2e/... -args -ginkgo.focus "QAT"
```

If you need to specify paths to your custom `kubeconfig` containing
embedded authentication info then add the `-kubeconfig` argument:

```bash
$ go test -v ./test/e2e/... -args -kubeconfig /path/to/kubeconfig
```

The full list of available options can be obtained with

```bash
$ go test ./test/e2e/... -args -help
```

Also it is possible to run the tests which don't depend on hardware
without a pre-configured Kubernetes cluster. Just make sure you have
[Kind](https://kind.sigs.k8s.io/) installed on your host and run

```
$ make test-with-kind
```
