tunning packages

This repository holds compiled packages for different linux distributions. These compiled packages are used for the optimization of KubeOVN.

How to use:

First check the distribution version of your system:

# for centOS
$ uname -r
3.10.0-1160.el7.x86_64
$ yum install kernel-devel --assumeno
Loaded plugins: fastestmirror
Loading mirror speeds from cached hostfile
 * base: mirrors.nju.edu.cn
 * extras: mirrors.maine.edu
 * updates: mirrors.seas.harvard.edu
Package kernel-devel-3.10.0-1160.59.1.el7.x86_64 already installed and latest version
Nothing to do
# for ubuntu
$ uname -r
5.11.0-43-generic
$ apt install linux-headers-generic --assume-no

Abort.

Use the result of uname -r as a standard VERSION, e.g. 5.11.0-43-generic in the example above.

But mark the more precise version number as VERSION, e.g. 3.10.0-1160.59.1.el7.x86_64.

The following optimisation options are available now:

1. module Fastpath

   Choose the right version for your distribution and download the package.

   # for centos
   $ wget https://github.com/kubeovn/tunning-packets/raw/master/rhel/centos7/${VERSION}/kube_ovn_fastpath.ko
   

   Then insert module into system:

   # for centos
   $ insmod ./kube_ovn_fastpath.ko
   

   Use dmesg to verify the module:

   [619631.323788] init_module,kube_ovn_fastpath_local_out
   [619631.323798] init_module,kube_ovn_fastpath_post_routing
   [619631.323800] init_module,kube_ovn_fastpath_pre_routing
   [619631.323801] init_module,kube_ovn_fastpath_local_in

   If the log exits then the module is installed.

2. module stt

   Also choose the right version for your distribution and download the package.

   # for centos
   $ wget https://github.com/lut777/tunning-packets/raw/master/rhel/centos7/${VERSION}/openvswitch-kmod-2.17.2-1.el7.x86_64.rpm
   
   # for ubuntu
   $ wget https://github.com/kubeovn/tunning-package/raw/main/debian/${UBUNTU-DISTRI}/${VERSION}/extra.tar.gz

   Then install the RPM package:

   # for centos
   $ rpm -i openvswitch-kmod-2.17.2-1.el7.x86_64.rpm
   
   # for ubuntu
   tar -zvxf ./ovs.tar.gz
   cd ./ovs/
   make install
   make modules_install
   cat > /etc/depmod.d/openvswitch.conf << EOF
   override openvswitch * extra
   override vport-* * extra
   EOF
   depmod -a
   cp debian/openvswitch-switch.init /etc/init.d/openvswitch-switch
   /etc/init.d/openvswitch-switch force-reload-kmod

   Verify the module:

   $ modprobe -c | grep vport | grep stt
   alias xxxxxxxx. vport_stt

   If the installation is smooth and verification passes, then the module is installed.

How to submit requirement:

​ Limited distributions are supported currently, as there are too many sub-versions.

​ So we have switched to a new form:

​ We recommend that users propose which versions they would like to support via PR. The steps are as follows:

1. add the distribution version and download url of the corresponding linux-header package to the file kernel.list in the corresponding distribution as a PR.

   e.g. add a new version 3.10.0-1160.49.1.el7.x86_64 in tunning-packets/rhel/centos7/kernel.list:

   3.10.0-1160.62.1.el7.x86_64 http://ftp.riken.jp/Linux/cern/centos/7/updates/x86_64/Packages/kernel-devel-3.10.0-1160.62.1.el7.x86_64.rpm
   3.10.0-1160.59.1.el7.x86_64 http://ftp.riken.jp/Linux/cern/centos/7/updates/x86_64/Packages/kernel-devel-3.10.0-1160.59.1.el7.x86_64.rpm
   3.10.0-1160.53.1.el7.x86_64 http://ftp.riken.jp/Linux/cern/centos/7/updates/x86_64/Packages/kernel-devel-3.10.0-1160.53.1.el7.x86_64.rpm
   # the new added line
   3.10.0-1160.49.1.el7.x86_64 http://ftp.riken.jp/Linux/cern/centos/7/updates/x86_64/Packages/kernel-devel-3.10.0-1160.49.1.el7.x86_64.rpm

   Note that the versions are added in descending order.
