+Open vSwitch with AF_XDP
+========================
+
+This document describes how to build and install Open vSwitch using
+AF_XDP netdev.
+
+.. warning::
+  The AF_XDP support of Open vSwitch is considered 'experimental',
+  and it is not compiled in by default.
+
+
+Introduction
+------------
+AF_XDP, Address Family of the eXpress Data Path, is a new Linux socket type
+built upon the eBPF and XDP technology.  It is aims to have comparable
+performance to DPDK but cooperate better with existing kernel's networking
+stack.  An AF_XDP socket receives and sends packets from an eBPF/XDP program
+attached to the netdev, by-passing a couple of Linux kernel's subsystems.
+As a result, AF_XDP socket shows much better performance than AF_PACKET.
+For more details about AF_XDP, please see linux kernel's
+Documentation/networking/af_xdp.rst
+
+
+AF_XDP Netdev
+-------------
+OVS has a couple of netdev types, i.e., system, tap, or
+dpdk.  The AF_XDP feature adds a new netdev types called
+"afxdp", and implement its configuration, packet reception,
+and transmit functions.  Since the AF_XDP socket, called xsk,
+operates in userspace, once ovs-vswitchd receives packets
+from xsk, the afxdp netdev re-uses the existing userspace
+dpif-netdev datapath.  As a result, most of the packet processing
+happens at the userspace instead of linux kernel.

+
+
+Build requirements
+------------------
+
+In addition to the requirements described in :doc:`general`, building Open
+vSwitch with AF_XDP will require the following:
+
+- libbpf from kernel source tree (kernel 5.0.0 or later)
+
+- Linux kernel XDP support, with the following options (required)
+
+  * CONFIG_BPF=y
+
+  * CONFIG_BPF_SYSCALL=y
+
+  * CONFIG_XDP_SOCKETS=y
+
+
+- The following optional Kconfig options are also recommended, but not
+  required:
+
+  * CONFIG_BPF_JIT=y (Performance)
+
+  * CONFIG_HAVE_BPF_JIT=y (Performance)
+
+  * CONFIG_XDP_SOCKETS_DIAG=y (Debugging)
+
+- Once your AF_XDP-enabled kernel is ready, if possible, run
+  **./xdpsock -r -N -z -i <your device>** under linux/samples/bpf.
+  This is an OVS independent benchmark tools for AF_XDP.
+  It makes sure your basic kernel requirements are met for AF_XDP.
+
+
+Installing
+----------
+For OVS to use AF_XDP netdev, it has to be configured with LIBBPF support.
+First, clone a recent version of Linux bpf-next tree::
+
+  git clone git://git.kernel.org/pub/scm/linux/kernel/git/bpf/bpf-next.git
+
+Second, go into the Linux source directory and build libbpf in the tools
+directory::
+
+  cd bpf-next/
+  cd tools/lib/bpf/
+  make && make install
+  make install_headers
+
+.. note::
+   Make sure xsk.h and bpf.h are installed in system's library path,
+   e.g. /usr/local/include/bpf/ or /usr/include/bpf/
+
+Make sure the libbpf.so is installed correctly::
+
+  ldconfig
+  ldconfig -p | grep libbpf
+
+Third, ensure the standard OVS requirements are installed and
+bootstrap/configure the package::
+
+  ./boot.sh && ./configure --enable-afxdp
+
+Finally, build and install OVS::
+
+  make && make install
+
+To kick start end-to-end autotesting::
+
+  uname -a # make sure having 5.0+ kernel
+  make check-afxdp TESTSUITEFLAGS='1'
+
+If a test case fails, check the log at::
+
+  cat tests/system-afxdp-testsuite.dir/001/system-afxdp-testsuite.log
+
+
+Setup AF_XDP netdev
+-------------------
+Before running OVS with AF_XDP, make sure the libbpf and libelf are
+set-up right::
+
+  ldd vswitchd/ovs-vswitchd
+
+Open vSwitch should be started using userspace datapath as described
+in :doc:`general`::
+
+  ovs-vswitchd ...
+  ovs-vsctl -- add-br br0 -- set Bridge br0 datapath_type=netdev
+
+Make sure your device driver support AF_XDP, and to use 1 PMD (on core 4)
+on 1 queue (queue 0) device, configure these options: **pmd-cpu-mask,
+pmd-rxq-affinity, and n_rxq**. The **xdpmode** can be "drv" or "skb"::
+
+  ethtool -L enp2s0 combined 1
+  ovs-vsctl set Open_vSwitch . other_config:pmd-cpu-mask=0x10
+  ovs-vsctl add-port br0 enp2s0 -- set interface enp2s0 type="afxdp" \
+    options:n_rxq=1 options:xdpmode=drv \
+    other_config:pmd-rxq-affinity="0:4"
+
+Or, use 4 pmds/cores and 4 queues by doing::
+
+  ethtool -L enp2s0 combined 4
+  ovs-vsctl set Open_vSwitch . other_config:pmd-cpu-mask=0x36
+  ovs-vsctl add-port br0 enp2s0 -- set interface enp2s0 type="afxdp" \
+    options:n_rxq=4 options:xdpmode=drv \
+    other_config:pmd-rxq-affinity="0:1,1:2,2:3,3:4"
+
+.. note::
+   pmd-rxq-affinity is optional. If not specified, system will auto-assign.
+
+To validate that the bridge has successfully instantiated, you can use the::
+
+  ovs-vsctl show
+
+Should show something like::
+
+  Port "ens802f0"
+   Interface "ens802f0"
+      type: afxdp
+      options: {n_rxq="1", xdpmode=drv}
+
+Otherwise, enable debugging by::
+
+  ovs-appctl vlog/set netdev_afxdp::dbg
+
+
+References
+----------
+Most of the design details are described in the paper presented at
+Linux Plumber 2018, "Bringing the Power of eBPF to Open vSwitch"[1],
+section 4, and slides[2][4].
+"The Path to DPDK Speeds for AF XDP"[3] gives a very good introduction
+about AF_XDP current and future work.

+
+Performance Tuning
+------------------
+The name of the game is to keep your CPU running in userspace, allowing PMD
+to keep polling the AF_XDP queues without any interferences from kernel.
+
+#. Make sure everything is in the same NUMA node (memory used by AF_XDP, pmd
+   running cores, device plug-in slot)
+
+#. Isolate your CPU by doing isolcpu at grub configure.
+
+#. IRQ should not set to pmd running core.
+
+#. The Spectre and Meltdown fixes increase the overhead of system calls.
+
+
+Debugging performance issue
+~~~~~~~~~~~~~~~~~~~~~~~~~~~
+While running the traffic, use linux perf tool to see where your cpu
+spends its cycle::
+
+  cd bpf-next/tools/perf
+  make
+  ./perf record -p `pidof ovs-vswitchd` sleep 10
+  ./perf report
+
+Measure your system call rate by doing::
+
+  pstree -p `pidof ovs-vswitchd`
+  strace -c -p <your pmd's PID>
+
+Or, use OVS pmd tool::
+
+  ovs-appctl dpif-netdev/pmd-stats-show
+
+
+Example Script
+--------------
+
+Below is a script using namespaces and veth peer::
+
+  #!/bin/bash
+  ovs-vswitchd --no-chdir --pidfile -vvconn -vofproto_dpif -vunixctl \
+    --disable-system --detach \
+  ovs-vsctl -- add-br br0 -- set Bridge br0 \
+    protocols=OpenFlow10,OpenFlow11,OpenFlow12,OpenFlow13,OpenFlow14 \
+    fail-mode=secure datapath_type=netdev
+  ovs-vsctl -- add-br br0 -- set Bridge br0 datapath_type=netdev
+
+  ip netns add at_ns0
+  ovs-appctl vlog/set netdev_afxdp::dbg
+
+  ip link add p0 type veth peer name afxdp-p0
+  ip link set p0 netns at_ns0
+  ip link set dev afxdp-p0 up
+  ovs-vsctl add-port br0 afxdp-p0 -- \
+    set interface afxdp-p0 external-ids:iface-id="p0" type="afxdp"
+
+  ip netns exec at_ns0 sh << NS_EXEC_HEREDOC
+  ip addr add "10.1.1.1/24" dev p0
+  ip link set dev p0 up
+  NS_EXEC_HEREDOC
+
+  ip netns add at_ns1
+  ip link add p1 type veth peer name afxdp-p1
+  ip link set p1 netns at_ns1
+  ip link set dev afxdp-p1 up
+
+  ovs-vsctl add-port br0 afxdp-p1 -- \
+    set interface afxdp-p1 external-ids:iface-id="p1" type="afxdp"
+  ip netns exec at_ns1 sh << NS_EXEC_HEREDOC
+  ip addr add "10.1.1.2/24" dev p1
+  ip link set dev p1 up
+  NS_EXEC_HEREDOC
+
+  ip netns exec at_ns0 ping -i .2 10.1.1.2
+
+
+Limitations/Known Issues
+------------------------
+#. Device's numa ID is always 0, need a way to find numa id from a netdev.
+#. No QoS support because AF_XDP netdev by-pass the Linux TC layer. A possible
+   work-around is to use OpenFlow meter action.
+#. AF_XDP device added to bridge, remove, and added again will fail.
+#. Most of the tests are done using i40e single port. Multiple ports and
+   also ixgbe driver also needs to be tested.
+#. No latency test result (TODO items)
+
+
+PVP using tap device
+--------------------
+Assume you have enp2s0 as physical nic, and a tap device connected to VM.
+First, start OVS, then add physical port::
+
+  ethtool -L enp2s0 combined 1
+  ovs-vsctl set Open_vSwitch . other_config:pmd-cpu-mask=0x10
+  ovs-vsctl add-port br0 enp2s0 -- set interface enp2s0 type="afxdp" \
+    options:n_rxq=1 options:xdpmode=drv \
+    other_config:pmd-rxq-affinity="0:4"
+
+Start a VM with virtio and tap device::
+
+  qemu-system-x86_64 -hda ubuntu1810.qcow \
+    -m 4096 \
+    -cpu host,+x2apic -enable-kvm \
+    -device virtio-net-pci,mac=00:02:00:00:00:01,netdev=net0,mq=on,\
+      vectors=10,mrg_rxbuf=on,rx_queue_size=1024 \
+    -netdev type=tap,id=net0,vhost=on,queues=8 \
+    -object memory-backend-file,id=mem,size=4096M,\
+      mem-path=/dev/hugepages,share=on \
+    -numa node,memdev=mem -mem-prealloc -smp 2
+
+Create OpenFlow rules::
+
+  ovs-vsctl add-port br0 tap0 -- set interface tap0
+  ovs-ofctl del-flows br0
+  ovs-ofctl add-flow br0 "in_port=enp2s0, actions=output:tap0"
+  ovs-ofctl add-flow br0 "in_port=tap0, actions=output:enp2s0"
+
+Inside the VM, use xdp_rxq_info to bounce back the traffic::
+
+  ./xdp_rxq_info --dev ens3 --action XDP_TX
+
+
+PVP using vhostuser device
+--------------------------
+First, build OVS with DPDK and AFXDP::
+
+  ./configure  --enable-afxdp --with-dpdk=<dpdk path>
+  make -j4 && make install
+
+Create a vhost-user port from OVS::
+
+  ovs-vsctl --no-wait set Open_vSwitch . other_config:dpdk-init=true
+  ovs-vsctl -- add-br br0 -- set Bridge br0 datapath_type=netdev \
+    other_config:pmd-cpu-mask=0xfff
+  ovs-vsctl add-port br0 vhost-user-1 \
+    -- set Interface vhost-user-1 type=dpdkvhostuser
+
+Start VM using vhost-user mode::
+
+  qemu-system-x86_64 -hda ubuntu1810.qcow \
+   -m 4096 \
+   -cpu host,+x2apic -enable-kvm \
+   -chardev socket,id=char1,path=/usr/local/var/run/openvswitch/vhost-user-1 \
+   -netdev type=vhost-user,id=mynet1,chardev=char1,vhostforce,queues=4 \
+   -device virtio-net-pci,mac=00:00:00:00:00:01,\
+      netdev=mynet1,mq=on,vectors=10 \
+   -object memory-backend-file,id=mem,size=4096M,\
+      mem-path=/dev/hugepages,share=on \
+   -numa node,memdev=mem -mem-prealloc -smp 2
+
+Setup the OpenFlow ruls::
+
+  ovs-ofctl del-flows br0
+  ovs-ofctl add-flow br0 "in_port=enp2s0, actions=output:vhost-user-1"
+  ovs-ofctl add-flow br0 "in_port=vhost-user-1, actions=output:enp2s0"
+
+Inside the VM, use xdp_rxq_info to drop or bounce back the traffic::
+
+  ./xdp_rxq_info --dev ens3 --action XDP_DROP
+  ./xdp_rxq_info --dev ens3 --action XDP_TX
+
+
+PCP container using veth
+------------------------
+Create namespace and veth peer devices::
+
+  ip netns add at_ns0
+  ip link add p0 type veth peer name afxdp-p0
+  ip link set p0 netns at_ns0
+  ip link set dev afxdp-p0 up
+  ip netns exec at_ns0 ip link set dev p0 up
+
+Attach the veth port to br0 (linux kernel mode)::
+
+  ovs-vsctl add-port br0 afxdp-p0 -- \
+    set interface afxdp-p0 options:n_rxq=1
+
+Or, use AF_XDP with skb mode::
+
+  ovs-vsctl add-port br0 afxdp-p0 -- \
+    set interface afxdp-p0 type="afxdp" options:n_rxq=1 options:xdpmode=skb
+
+Setup the OpenFlow rules::
+
+  ovs-ofctl del-flows br0
+  ovs-ofctl add-flow br0 "in_port=enp2s0, actions=output:afxdp-p0"
+  ovs-ofctl add-flow br0 "in_port=afxdp-p0, actions=output:enp2s0"
+
+In the namespace, run drop or bounce back the packet::
+
+  ip netns exec at_ns0 ./xdp_rxq_info --dev p0 --action XDP_DROP
+  ip netns exec at_ns0 ./xdp_rxq_info --dev p0 --action XDP_TX
