Introduction

Intel® QuickAssist Technology (QAT) provides hardware acceleration for security (cryptography) and compression. These instructions cover the steps for the latest Ubuntu LTS release which already include the QAT host driver. These instructions can be adapted to any Linux distribution. These instructions guide the user on how to download the kernel sources, compile kernel driver modules against those sources, and load them onto the host as well as preparing a specially built Kata Containers kernel and custom Kata Containers rootfs.

Steps to enable Intel® QAT in Kata Containers

There are some steps to complete only once, some steps to complete with every reboot, and some steps to complete when the host kernel changes.

Script variables

The following list of variables must be set before running through the scripts. These variables refer to locations to store modules and configuration files on the host and links to the drivers to use. Modify these as needed to point to updated drivers or different install locations.

Set environment variables (Every Reboot)

Make sure to check 01.org for the latest driver.

$ export QAT_DRIVER_VER=qat1.7.l.4.14.0-00031.tar.gz
$ export QAT_DRIVER_URL=https://downloadmirror.intel.com/30178/eng/${QAT_DRIVER_VER}
$ export QAT_CONF_LOCATION=~/QAT_conf
$ export QAT_DOCKERFILE=https://raw.githubusercontent.com/intel/intel-device-plugins-for-kubernetes/main/demo/openssl-qat-engine/Dockerfile
$ export QAT_SRC=~/src/QAT
$ export GOPATH=~/src/go
$ export KATA_KERNEL_LOCATION=~/kata
$ export KATA_ROOTFS_LOCATION=~/kata

Prepare the Ubuntu Host

The host could be a bare metal instance or a virtual machine. If using a virtual machine, make sure that KVM nesting is enabled. The following instructions reference an Intel® C62X chipset. Some of the instructions must be modified if using a different Intel® QAT device. The Intel® QAT chipset can be identified by executing the following.

Identify which PCI Bus the Intel® QAT card is on

$ for i in 0434 0435 37c8 1f18 1f19; do lspci -d 8086:$i; done

Install necessary packages for Ubuntu

These packages are necessary to compile the Kata kernel, Intel® QAT driver, and to prepare the rootfs for Kata. Docker also needs to be installed to be able to build the rootfs. To test that everything works a Kubernetes pod is started requesting Intel® QAT resources. For the pass through of the virtual functions the kernel boot parameter needs to have INTEL_IOMMU=on.

$ sudo apt update
$ sudo apt install -y golang-go build-essential python pkg-config zlib1g-dev libudev-dev bison libelf-dev flex libtool automake autotools-dev autoconf bc libpixman-1-dev coreutils libssl-dev
$ sudo sed -i 's/GRUB_CMDLINE_LINUX_DEFAULT=""/GRUB_CMDLINE_LINUX_DEFAULT="intel_iommu=on"/' /etc/default/grub
$ sudo update-grub
$ sudo reboot

Download Intel® QAT drivers

This will download the Intel® QAT drivers. Make sure to check the website for the latest version.

$ mkdir -p $QAT_SRC
$ cd $QAT_SRC
$ curl -L $QAT_DRIVER_URL | tar zx

Copy Intel® QAT configuration files and enable virtual functions

Modify the instructions below as necessary if using a different Intel® QAT hardware platform. You can learn more about customizing configuration files at the Intel® QAT Engine repository This section starts from a base config file and changes the SSL section to SHIM to support the OpenSSL engine. There are more tweaks that you can make depending on the use case and how many Intel® QAT engines should be run. You can find more information about how to customize in the Intel® QuickAssist Technology Software for Linux* - Programmer's Guide.

Note: This section assumes that a Intel® QAT c6xx platform is used.

$ mkdir -p $QAT_CONF_LOCATION
$ cp $QAT_SRC/quickassist/utilities/adf_ctl/conf_files/c6xxvf_dev0.conf.vm $QAT_CONF_LOCATION/c6xxvf_dev0.conf
$ sed -i 's/\[SSL\]/\[SHIM\]/g' $QAT_CONF_LOCATION/c6xxvf_dev0.conf

Expose and Bind Intel® QAT virtual functions to VFIO-PCI (Every reboot)

To enable virtual functions, the host OS should have IOMMU groups enabled. In the UEFI Firmware Intel® Virtualization Technology for Directed I/O (Intel® VT-d) must be enabled. Also, the kernel boot parameter should be intel_iommu=on or intel_iommu=ifgx_off. This should have been set from the instructions above. Check the output of /proc/cmdline to confirm. The following commands assume you installed an Intel® QAT card, IOMMU is on, and VT-d is enabled. The vendor and device ID add to the VFIO-PCI driver so that each exposed virtual function can be bound to the VFIO-PCI driver. Once complete, each virtual function passes into a Kata Containers container using the PCIe device passthrough feature. For Kubernetes, the Intel device plugin for Kubernetes handles the binding of the driver, but the VF’s still must be enabled.

$ sudo modprobe vfio-pci
$ QAT_PCI_BUS_PF_NUMBERS=$((lspci -d :435 && lspci -d :37c8 && lspci -d :19e2 && lspci -d :6f54) | cut -d ' ' -f 1)
$ QAT_PCI_BUS_PF_1=$(echo $QAT_PCI_BUS_PF_NUMBERS | cut -d ' ' -f 1)
$ echo 16 | sudo tee /sys/bus/pci/devices/0000:$QAT_PCI_BUS_PF_1/sriov_numvfs
$ QAT_PCI_ID_VF=$(cat /sys/bus/pci/devices/0000:${QAT_PCI_BUS_PF_1}/virtfn0/uevent | grep PCI_ID)
$ QAT_VENDOR_AND_ID_VF=$(echo ${QAT_PCI_ID_VF/PCI_ID=} | sed 's/:/ /')
$ echo $QAT_VENDOR_AND_ID_VF | sudo tee --append /sys/bus/pci/drivers/vfio-pci/new_id

Loop through all the virtual functions and bind to the VFIO driver

$ for f in /sys/bus/pci/devices/0000:$QAT_PCI_BUS_PF_1/virtfn*
  do QAT_PCI_BUS_VF=$(basename $(readlink $f))
   echo $QAT_PCI_BUS_VF | sudo tee --append /sys/bus/pci/drivers/c6xxvf/unbind
   echo $QAT_PCI_BUS_VF | sudo tee --append /sys/bus/pci/drivers/vfio-pci/bind
  done

Check Intel® QAT virtual functions are enabled

If the following command returns empty, then the virtual functions are not properly enabled. This command checks the enumerated device IDs for just the virtual functions. Using the Intel® QAT as an example, the physical device ID is 37c8 and virtual function device ID is 37c9. The following command checks if VF's are enabled for any of the currently known Intel® QAT device ID's. The following ls command should show the 16 VF's bound to VFIO-PCI.

$ for i in 0442 0443 37c9 19e3; do lspci -d 8086:$i; done

Another way to check is to see what PCI devices that VFIO-PCI is mapped to. It should match the device ID's of the VF's.

$ ls -la /sys/bus/pci/drivers/vfio-pci

Prepare Kata Containers

Download Kata kernel Source

This example automatically uses the latest Kata kernel supported by Kata. It follows the instructions from the packaging kernel repository and uses the latest Kata kernel config. There are some patches that must be installed as well, which the build-kernel.sh script should automatically apply. If you are using a different kernel version, then you might need to manually apply them. Since the Kata Containers kernel has a minimal set of kernel flags set, you must create a Intel® QAT kernel fragment with the necessary CONFIG_CRYPTO_* options set. Update the config to set some of the CRYPTO flags to enabled. This might change with different kernel versions. The following instructions were tested with kernel v5.4.0-64-generic.

$ mkdir -p $GOPATH
$ cd $GOPATH
$ go get -v github.com/kata-containers/kata-containers
$ cat << EOF > $GOPATH/src/github.com/kata-containers/kata-containers/tools/packaging/kernel/configs/fragments/common/qat.conf

CONFIG_CRYPTO_AUTHENC=y
CONFIG_CRYPTO_DH=y
EOF
$ $GOPATH/src/github.com/kata-containers/kata-containers/tools/packaging/kernel/build-kernel.sh setup

Build Kata kernel

$ cd $GOPATH
$ export LINUX_VER=$(ls -d kata-linux-*)
$ sed -i 's/EXTRAVERSION =/EXTRAVERSION = .qat.container/' $LINUX_VER/Makefile
$ $GOPATH/src/github.com/kata-containers/kata-containers/tools/packaging/kernel/build-kernel.sh build

Copy Kata kernel

$ export KATA_KERNEL_NAME=vmlinux-${LINUX_VER}_qat
$ mkdir -p $KATA_KERNEL_LOCATION
$ cp ${GOPATH}/${LINUX_VER}/vmlinux ${KATA_KERNEL_LOCATION}/${KATA_KERNEL_NAME}

Prepare Kata root filesystem

These instructions build upon the OS builder instructions located in the Developer Guide. At this point it is recommended that Docker is installed first, and then Kata-deploy is use to install Kata. This will make sure that the correct agent version is installed into the rootfs in the steps below.

The following instructions use Ubuntu as the root filesystem with systemd as the init and will add in the kmod binary, which is not a standard binary in a Kata rootfs image. The kmod binary is necessary to load the Intel® QAT kernel modules when the virtual machine rootfs boots.

$ export OSBUILDER=$GOPATH/src/github.com/kata-containers/kata-containers/tools/osbuilder
$ export ROOTFS_DIR=${OSBUILDER}/rootfs-builder/rootfs
$ export EXTRA_PKGS='kmod'

Make sure that the kata-agent version matches the installed kata-runtime version. Also make sure the kata-runtime install location is in your PATH variable. The following AGENT_VERSION can be set manually to match the kata-runtime version if the following commands don't work.

$ export PATH=$PATH:/opt/kata/bin
$ cd $GOPATH
$ export AGENT_VERSION=$(kata-runtime version | head -n 1 | grep -o "[0-9.]\+")
$ cd ${OSBUILDER}/rootfs-builder
$ sudo rm -rf ${ROOTFS_DIR}
$ script -fec 'sudo -E GOPATH=$GOPATH USE_DOCKER=true SECCOMP=no ./rootfs.sh ubuntu'

Compile Intel® QAT drivers for Kata Containers kernel and add to Kata Containers rootfs

After the Kata Containers kernel builds with the proper configuration flags, you must build the Intel® QAT drivers against that Kata Containers kernel version in a similar way they were previously built for the host OS. You must set the KERNEL_SOURCE_ROOT variable to the Kata Containers kernel source directory and build the Intel® QAT drivers again. The make command will install the Intel® QAT modules into the Kata rootfs.

$ cd $GOPATH
$ export LINUX_VER=$(ls -d kata*)
$ export KERNEL_MAJOR_VERSION=$(awk '/^VERSION =/{print $NF}' $GOPATH/$LINUX_VER/Makefile)
$ export KERNEL_PATHLEVEL=$(awk '/^PATCHLEVEL =/{print $NF}' $GOPATH/$LINUX_VER/Makefile)
$ export KERNEL_SUBLEVEL=$(awk '/^SUBLEVEL =/{print $NF}' $GOPATH/$LINUX_VER/Makefile)
$ export KERNEL_EXTRAVERSION=$(awk '/^EXTRAVERSION =/{print $NF}' $GOPATH/$LINUX_VER/Makefile)
$ export KERNEL_ROOTFS_DIR=${KERNEL_MAJOR_VERSION}.${KERNEL_PATHLEVEL}.${KERNEL_SUBLEVEL}${KERNEL_EXTRAVERSION}
$ cd $QAT_SRC
$ KERNEL_SOURCE_ROOT=$GOPATH/$LINUX_VER ./configure --enable-icp-sriov=guest
$ sudo -E make all -j $($(nproc ${CI:+--ignore 1}))
$ sudo -E make INSTALL_MOD_PATH=$ROOTFS_DIR qat-driver-install -j $($(nproc ${CI:+--ignore 1}))

The usdm_drv module also needs to be copied into the rootfs modules path and depmod should be run.

$ sudo cp $QAT_SRC/build/usdm_drv.ko $ROOTFS_DIR/lib/modules/${KERNEL_ROOTFS_DIR}/updates/drivers  
$ sudo depmod -a -b ${ROOTFS_DIR} ${KERNEL_ROOTFS_DIR}
$ cd ${OSBUILDER}/image-builder
$ script -fec 'sudo -E USE_DOCKER=true ./image_builder.sh ${ROOTFS_DIR}'

Note: Ignore any errors on modules.builtin and modules.order when running depmod.

Copy Kata rootfs

$ mkdir -p $KATA_ROOTFS_LOCATION
$ cp ${OSBUILDER}/image-builder/kata-containers.img $KATA_ROOTFS_LOCATION

Verify Intel® QAT works in a container

The following instructions uses a OpenSSL Dockerfile that builds the Intel® QAT engine to allow OpenSSL to offload crypto functions. It is a convenient way to test that VFIO device passthrough for the Intel® QAT VF’s are working properly with the Kata Containers VM.

Build OpenSSL Intel® QAT engine container

Use the OpenSSL Intel® QAT Dockerfile to build a container image with an optimized OpenSSL engine for Intel® QAT. Using docker build with the Kata Containers runtime can sometimes have issues. Therefore, make sure that runc is the default Docker container runtime.

$ cd $QAT_SRC
$ curl -O $QAT_DOCKERFILE
$ sudo docker build -t openssl-qat-engine .

Note: The Intel® QAT driver version in this container might not match the Intel® QAT driver compiled and loaded on the host when compiling.

Test Intel® QAT with the ctr tool

The ctr tool can be used to interact with the containerd daemon. It may be more convenient to use this tool to verify the kernel and image instead of setting up a Kubernetes cluster. The correct Kata runtimes need to be added to the containerd config.toml. Below is a sample snippet that can be added to allow QEMU and Cloud Hypervisor (CLH) to work with ctr.

[plugins.cri.containerd.runtimes.kata-qemu]
  runtime_type = "io.containerd.kata-qemu.v2"
  privileged_without_host_devices = true
  pod_annotations = ["io.katacontainers.*"]
  [plugins.cri.containerd.runtimes.kata-qemu.options]
    ConfigPath = "/opt/kata/share/defaults/kata-containers/configuration-qemu.toml"
[plugins.cri.containerd.runtimes.kata-clh]
  runtime_type = "io.containerd.kata-clh.v2"
  privileged_without_host_devices = true
  pod_annotations = ["io.katacontainers.*"]
  [plugins.cri.containerd.runtimes.kata-clh.options]
    ConfigPath = "/opt/kata/share/defaults/kata-containers/configuration-clh.toml"

In addition, containerd expects the binary to be in /usr/local/bin so add this small script so that it redirects to be able to use either QEMU or Cloud Hypervisor with Kata.

$ echo '#!/usr/bin/env bash' | sudo tee /usr/local/bin/containerd-shim-kata-qemu-v2
$ echo 'KATA_CONF_FILE=/opt/kata/share/defaults/kata-containers/configuration-qemu.toml /opt/kata/bin/containerd-shim-kata-v2 $@' | sudo tee -a /usr/local/bin/containerd-shim-kata-qemu-v2
$ sudo chmod +x /usr/local/bin/containerd-shim-kata-qemu-v2
$ echo '#!/usr/bin/env bash' | sudo tee /usr/local/bin/containerd-shim-kata-clh-v2
$ echo 'KATA_CONF_FILE=/opt/kata/share/defaults/kata-containers/configuration-clh.toml /opt/kata/bin/containerd-shim-kata-v2 $@' | sudo tee -a /usr/local/bin/containerd-shim-kata-clh-v2
$ sudo chmod +x /usr/local/bin/containerd-shim-kata-clh-v2

After the OpenSSL image is built and imported into containerd, a Intel® QAT virtual function exposed in the step above can be added to the ctr command. Make sure to change the /dev/vfio number to one that actually exists on the host system. When using the ctr tool, theconfiguration.toml for Kata needs to point to the custom Kata kernel and rootfs built above and the Intel® QAT modules in the Kata rootfs need to load at boot. The following steps assume that kata-deploy was used to install Kata and QEMU is being tested. If using a different hypervisor, different install method for Kata, or a different Intel® QAT chipset then the command will need to be modified.

Note: The following was tested with containerd v1.4.6.

$ config_file="/opt/kata/share/defaults/kata-containers/configuration-qemu.toml"
$ sudo sed -i "/kernel =/c kernel = "\"${KATA_ROOTFS_LOCATION}/${KATA_KERNEL_NAME}\""" $config_file
$ sudo sed -i "/image =/c image = "\"${KATA_KERNEL_LOCATION}/kata-containers.img\""" $config_file
$ sudo sed -i -e 's/^kernel_params = "\(.*\)"/kernel_params = "\1 modules-load=usdm_drv,qat_c62xvf"/g' $config_file 
$ sudo docker save -o openssl-qat-engine.tar openssl-qat-engine:latest
$ sudo ctr images import openssl-qat-engine.tar
$ sudo ctr run --runtime io.containerd.run.kata-qemu.v2 --privileged -t --rm --device=/dev/vfio/180 --mount type=bind,src=/dev,dst=/dev,options=rbind:rw --mount type=bind,src=${QAT_CONF_LOCATION}/c6xxvf_dev0.conf,dst=/etc/c6xxvf_dev0.conf,options=rbind:rw  docker.io/library/openssl-qat-engine:latest bash

Below are some commands to run in the container image to verify Intel® QAT is working

     [ available ]

Test Intel® QAT in Kubernetes

Start a Kubernetes cluster with containerd as the CRI. The host should already be setup with 16 virtual functions of the Intel® QAT card bound to VFIO-PCI. Verify this by looking in /dev/vfio for a listing of devices. You might need to disable Docker before initializing Kubernetes. Be aware that the OpenSSL container image built above will need to be exported from Docker and imported into containerd.

If Kata is installed through kata-deploy there will be multiple configuration.toml files associated with different hypervisors. Rather than add in the custom Kata kernel, Kata rootfs, and kernel modules to each configuration.toml as the default, instead use annotations in the Kubernetes YAML file to tell Kata which kernel and rootfs to use. The easy way to do this is to use kata-deploy which will install the Kata binaries to /opt and properly configure the /etc/containerd/config.toml with annotation support. However, the configuration.toml needs to enable support for annotations as well. The following configures both QEMU and Cloud Hypervisor configuration.toml files that are currently available with Kata Container versions 2.0 and higher.

$ sudo sed -i 's/enable_annotations\s=\s\[\]/enable_annotations = [".*"]/' /opt/kata/share/defaults/kata-containers/configuration-qemu.toml
$ sudo sed -i 's/enable_annotations\s=\s\[\]/enable_annotations = [".*"]/' /opt/kata/share/defaults/kata-containers/configuration-clh.toml

Export the OpenSSL image from Docker and import into containerd.

$ sudo docker save -o openssl-qat-engine.tar openssl-qat-engine:latest
$ sudo ctr -n=k8s.io images import openssl-qat-engine.tar

The Intel® QAT Plugin needs to be started so that the virtual functions can be discovered and used by Kubernetes.

The following YAML file can be used to start a Kata container with Intel® QAT support. If Kata is installed with kata-deploy, then the containerd configuration.toml should have all of the Kata runtime classes already populated and annotations supported. To use a Intel® QAT virtual function, the Intel® QAT plugin needs to be started after the VF's are bound to VFIO-PCI as described above. Edit the following to point to the correct Kata kernel and rootfs location built with Intel® QAT support.

Troubleshooting

Check that /dev/vfio has VF’s enabled.

$ ls /dev/vfio
57  58  59  60  61  62  63  64  65  66  67  68  69  70  71  72  vfio

Check that the modules load when inside the Kata Container.

bash-5.0# egrep "qat|usdm_drv" /proc/modules
qat_c62xvf 16384 - - Live 0x0000000000000000 (O)
usdm_drv 86016 - - Live 0x0000000000000000 (O)
intel_qat 184320 - - Live 0x0000000000000000 (O)

Verify that at least the first c6xxvf_dev0.conf file mounts inside the container image in /etc. You will need one configuration file for each VF passed into the container.

bash-5.0# ls /etc
c6xxvf_dev0.conf   c6xxvf_dev11.conf  c6xxvf_dev14.conf  c6xxvf_dev3.conf  c6xxvf_dev6.conf  c6xxvf_dev9.conf  resolv.conf
c6xxvf_dev1.conf   c6xxvf_dev12.conf  c6xxvf_dev15.conf  c6xxvf_dev4.conf  c6xxvf_dev7.conf  hostname
c6xxvf_dev10.conf  c6xxvf_dev13.conf  c6xxvf_dev2.conf   c6xxvf_dev5.conf c6xxvf_dev8.conf  hosts

Check dmesg inside the container to see if there are any issues with the Intel® QAT driver.
If there are issues building the OpenSSL Intel® QAT container image, then check to make sure that runc is the default runtime for building container.

$ cat /etc/systemd/system/docker.service.d/50-runtime.conf
[Service]
Environment="DOCKER_DEFAULT_RUNTIME=--default-runtime runc"

Optional Scripts

Verify Intel® QAT card counters are incremented

To check the built in firmware counters, the Intel® QAT driver has to be compiled and installed to the host and can't rely on the built in host driver. The counters will increase when the accelerator is actively being used. To verify Intel® QAT is actively accelerating the containerized application, use the following instructions to check if any of the counters increment. Make sure to change the PCI Device ID to match whats in the system.

$ for i in 0434 0435 37c8 1f18 1f19; do lspci -d 8086:$i; done
$ sudo watch cat /sys/kernel/debug/qat_c6xx_0000\:b1\:00.0/fw_counters
$ sudo watch cat /sys/kernel/debug/qat_c6xx_0000\:b3\:00.0/fw_counters
$ sudo watch cat /sys/kernel/debug/qat_c6xx_0000\:b5\:00.0/fw_counters
