[pve-devel] [PATCH] add dpdk support

[Alexandre Derumier]

it's add dpdk support.
to enable it, we need to add support in ifupdown scripts later.

from doc:

Since Open vSwitch >= 2.6 the configuration of DPDK features has changed.
Instead of providing DPDK_OPTS in /etc/default/openvswitch-switch one now has
to use ovs-vsctl to enter the config into the database.

An example basic configuration workflow might look like:
 # Enable DPDK
 $ ovs-vsctl set Open_vSwitch . "other_config:dpdk-init=true"
 # run on cores 3,4 8,9
 $ ovs-vsctl set Open_vSwitch . "other_config:dpdk-lcore-mask=0x318"
 # Allocate 2G huge pages (not Numa node aware)
 $ ovs-vsctl set Open_vSwitch . "other_config:dpdk-alloc-mem=2048"
 # group/permissions for vhost-user sockets (required to work with libvirt/qemu)
 $ ovs-vsctl set Open_vSwitch . \
    "other_config:dpdk-extra=--vhost-owner libvirt-qemu:kvm --vhost-perm 0666"

There are also tunables like:
 $ ovs-vsctl set Open_vSwitch . "other_config:pmd-cpu-mask=0x318"
 $ ovs-vsctl set Open_vSwitch . "other_config:n-dpdk-rxqs=4"
