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 OSX, Fedora 23,
Windows (via appveyor), and FreeBSD 10.3; the v11 has had very basic testing
applied (start, configure some of the settings). I have removed ACKs and
Tested-bys for some of the patches since they underwent changes that I felt
disqualified continued use of the Acked-by: and Tested-by: tags.
Travis-ci build: https://travis-ci.org/orgcandman/ovs/builds/120081527
Appveyor build: https://ci.appveyor.com/project/orgcandman/ovs/build/1.0.9
This is a resend due to an accidentally omitted hunk in 4/8.
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
v12:
* Rebased to latest upstream
* Dropped path canonicalization
* Squashed NEWS changes into their specific commits.
