Currently, configuration of DPDK parameters is done via the command line through a --dpdk **OPTIONS** -- command line argument. This has a number of challenges, including: * It must be the first option passed to ovs-vswitchd * It is the only datapath feature in OVS to be configured on the command line * It requires specialized knowledge of sub-component command switches * It also inteprets non-EAL arguments (confusing users) * It is a broken model for datapath configuration.
This series brings the following changes to openvswitch: * All DPDK options are taken from the ovs database rather than the command line * Non-EAL arguments also have separate database entries * DPDK lcores are optionally auto-assigned to a single core based on the bridge coremask. * DPDK options have default behaviors * Updated documentation This series has been build tested (including `make check`) on Fedora 23, OS X Windows (via appveyor), and FreeBSD 10.3; the v13 has had very basic testing applied (start, configure some of the settings). Travis-ci build: https://travis-ci.org/orgcandman/ovs/builds/126691300 Appveyor build: https://ci.appveyor.com/project/orgcandman/ovs/build/1.0.13 A huge round of thanks on the work so far should be given to the following folks (in alphabetical order): * Ben Pfaff (Reviews, vhost-sock-dir escape suggestion) * Christian Erhardt (Testing) * Daniele Di Proietto (Reviews, general suggestions) * Flavio Leitner (Original efforts, reviews) * Kevin Traynor (Testing, general suggestions, reviews, doc reviews) * Panu Matilainen (Initialization ideas, eal arguments ideas, reviews) * RobertX Wojciechowicz (Testing, general suggestions) * Sean Mooney (Testing, general suggestions) Previous series: http://openvswitch.org/pipermail/dev/2016-April/069025.html v13: * Rebased to latest upstream * Addressed sparse errors * Removed the dpdk-mem-channels option * Switched to using the other_config smap directly. * Moved the netdev_dpdk_register() to the dpdk_init__ routine.
