DPDK Community Awards Recognize Development Excellence

By Blog

For the past three years, the DPDK developer community has honored some of the most outstanding contributions across the project over the past year. While things are quite different this year, we still wanted to take some time to call out some of the amazing success of our developers. While normally, the community meets together in person for the DPDK Userspace Summit (previous locations include Bordeaux, France and Dublin, Ireland) to share knowledge, collaborate on best practices and community alignment, this year’s event was held virtually due to the COVID-19 pandemic. 

Not to break tradition, 2020 winners were still recognized during the event on September 22’s Opening Remarks by  DPDK Board Chair Jim St. Leger. We were pleased to welcome even more attendees to this year’s event, given folks were able to join from their own homes. 

Please join us in congratulating all of our nominees and winners!

Creating a CI Testbed for DPDK

By Blog

By Lincoln Lavoie, UNH-IOL, Principal Engineer

A little more than 3 years ago, we set out to improve the qualities and capabilities of the continuous integration (CI) testing of the DPDK source code and new patches.  Now, it’s not uncommon for testing to come last in the process, and sometimes it doesn’t receive it’s fair share of attention.  Which of us hasn’t worked on a project, with the boss pushing off the testing efforts or milestones, in order to allow “just that bit more” focus or expansion on the features or customer wishes for the project?  However, as DPDK has matured and is a key foundation for many applications and deployments, we need to ensure the stability and robustness of the codebase and incoming patches.

Enter the Community CI team, a virtual team of DPDK community members who meet regularly and help maintain all of the tooling that enables the testing activities.  We’re working to better organize and support the testing resources available to the DPDK development teams.  Today, there are 3 primary testing sources, running as TravisCI, Intel’s hosted lab, and the community lab hosted at the UNH-IOL. Each of the “labs” provides results back to the DPDK project’s patchwork tracking system, and tests different aspects of the “code,” ranging from compile and unit tests, to performance and functionality tests on bare-metal with real NICs and drivers. 

We thought it might be worthwhile to spend a few words on a blog to highlight what testing is already running, what testing is under development, and finally, where do we see things going from here.  Starting with the Travis CI systems, which are triggered from a github robot that is tracking commits on the main branch, running compile and unit testing across both x86 and aarch64 architectures, with cross compiles to 32-bit, all on top of the Ubuntu OS.  The robot and CI jobs for this integration have been developed and maintained largely by our Redhat peers, so, shoutouts where they’re due, “great job guys!”  You can check out the Travis CI builds here:

Next up, Intel’s hosted lab, where they are running compile testing across a number of different operating systems on x86 hardware.  The operating systems range from Linux distros, to FreeBSD, and even Windows.  Adding another dimension, the compilation is also checked using both Makefile and Meson.  The system is tracking both the main branch and as well as providing results for patches, before their merge onto the main, and provides early feedback to the patch submitter if issues pop up from a patch, afterall, “who knew” that approach didn’t work over all of DPDK’s supported OSes (well, now you know).  Intel’s support in providing both the hosted lab environment and keeping things running smoothly is a great help, “thanks Intel team!”  You can see a sample of the Intel hosted lab output in patchworks here:

Lastly, for the currently operating testing, is the community lab, hosted at the UNH-IOL.  Testing in the community lab is also tracking both the main branch and submitted patches, providing a combination of compile, unit testing, functional testing, and performance testing.  The compile and unit testing also add one additional dimension, with some cooperation to downstream projects, such as Open vSwitch and SPDK, providing early detection of a patch breaking outside of DPDK directly.  For the functional and performance testing, the lab hosts a number of “bare-metal” systems with NICs provided by DPDK member companies, including Broadcom, Intel, Mellanox, and NXP currently.  The performance testing runs a throughput test on each NIC (in some cases there are multiple speeds or hardware variants included), checking for a drop in forwarding performance from a well known reference.  Gold and Silver DPDK member companies are eligible to submit hardware for hosting in the community lab and are strongly encouraged to do so by the governing and tech boards of DPDK, as this directly expands the testing coverages.  Functional testing is the newest and growing aspect within the community lab output, adding more tests running on “bare-metal”, based on the DTS (DPDK Test Suite) project.  Aiming to provide majority coverage for the NIC features list.  The community lab results also feed directly into the patchwork system, with additional information available on the lab portal as well:

Looking to the future, there are two efforts currently underway.  First, the robot that is tracking the github main branch is being extended to also drive builds on the OpenSUSE Build Service (OBS), further extending that coverage to more OS / build variants.  Second is the expansion of the feature testing coverage, which is focused on extending and updating the DTS coverage, with that work driving back into the functional testing run in the community lab.  

The Community CI team meets every other week, on Thursdays, at 1pm UTC.  All DPDK community members and maintainers are welcome to join and participate in the discussions, just drop a line to  We hope to see you there!

DPDK Governing board Update – July 2020

By Blog

The DPDK Project Governing board held a “virtual” meeting on July 13th, welcoming both Doug Stamper from Microsoft and Marvell’s new representative, Prasun Kapoor, to the board. Bruce Richardson (of Intel) rotated into the Technical Board representative seat, previously held by Thomas Monjalon (of Mellanox/NVIDIA), in Q3. Note, the Technical Board seat is rotated among Technical Board members on a quarterly basis.

It was noted that 20.08 RC2 went out this week, and it’s shaping up to be a big release! The DPDK project is looking for more code reviewers. If you are an active contributor to DPDK, we invite you to help review your fellow contributors’ patches; help us collectively improve DPDK releases (team work makes the dream work). We would like to thank the entire DPDK developer community who does the hard work that makes our project what it is.

The board recognized the ongoing efforts by Stephen Hemminger (Microsoft) and project maintainers to adopt more inclusive code language, with the replacement of terms like “Blacklist-Whitelist” and “Master-Slave.” Inclusive language aims to avoid expressions and terms that could be perceived as racist, sexist, ableist, or generally biased, prejudiced or demeaning to any particular group of people. DPDK joins other open source groups, including the Linux Kernel community, in working towards improving the use of inclusive language blocks. We know these changes require significant work. We are appreciative to the commitment of our entire community to support the transition to more inclusive terminology in the upcoming 20.11 release.

Additional updates from the Governing Board:

Updated DPDK Charter: Following up on our earlier summer update, the Governing Board, in conjunction with the Technical Board, concluded its months-long review and revision of the DPDK Charter, presenting it for ratification to the Governing Board at the meeting this week. The Governing Board unanimously approved the charter revisions in their entirety.

The edits bring the Charter up-to-date and serve as a current reflection of the project as it is today. The latest charter is available at, with changes noted in the table. Please take a look.

Events: We are moving solely to virtual events this year. The DPDK Summit Userspace event will take place virtually September 22-23. Registration is now live, and we encourage you to register early. Be on the lookout for agenda updates.

Budget: The Board has updated the budget to reflect our real-time changes as a result of the impact of COVID-19.

Lab: A sub-team has been working with the DPDK Community Lab team, including UNH-IOL. We are making good progress to properly resource, fund, and improve our lab’s community benefit.

Member Outreach: As mentioned earlier this summer, the board has also started a sub-committee that is looking to grow the DPDK Project’s membership. If you have any suggestions for companies or individuals that we should reach out to, please let us know.

Thank you for your continued engagement with the DPDK community! We hope everyone is staying healthy and keeping busy during these uncertain times

DPDK Community Update – Summer 2020

By Blog

We hope you are keeping safe and healthy, as we all adjust to the new normal we find ourselves in, with coronavirus and social unrest around us.  We’re proud of the leadership of our technical community to tackle our own issues and moving to more inclusive language, removing divisive terminology (e.g master/slave) that does not reflect our community values. Thank you for your leadership and work. It is greatly appreciated.

The DPDK project Governing Board, Technical Board, Marketing and other working groups have been busy over the past couple months. 

The Governing Board has held two meetings since the lock-downs went into effect, in April and early June, reassessing the project budget, marketing and event plans, while the Technical Board continued to focus on the technical priorities of DPDK, with the recent release of 20.05. Our community continues their stellar reputation of delivering our releases on time. Well done!

As we will not be able to meet in person for some time, and unable to provide the usual Governing Board readout on stage at one of the DPDK Summits, we wanted to provide a short written update, that we will continue on a regular basis moving forward. And we do apologize for not providing more timely governing board activity updates in the past. We will strive to improve and keep the communication open and timely. Do not hesitate to reach out should you have any questions. 

DPDK Welcomes New Members

Our community thrives through the work of the community and the financial support enabled by our members. We are pleased to share recent additions to the DPDK Project membership. The DPDK Project welcomes Microsoft as our newest Gold member, with Mr. Douglas Stamper joining the Governing Board, bringing his expertise with DPDK and the Windows ecosystem. Additionally, AMD joined as a Silver member. Welcome to both companies!



DPDK Userspace Summit 2020 Moves to a Virtual Format

Due to the prevailing coronavirus situation across the globe and related travel restrictions, we made the difficult decision to transition the DPDK Userspace Summit to a virtual experience, happening September 22-23. The Call for proposals and registration are now open. Note that the CFP closes July 12. Please consider submitting an abstract! We hope you will join us! 

DPDK will continue to monitor the prevailing situation and assess the feasibility of safely holding physical community gatherings. Please bear with us. 

  • China and Japan events are on hold. It is currently looking unlikely we can make in-person events happen in 2020. 
  • The US DPDK Summit event is pushed out to Q1 of 2021.

Strategic and Financial Update

It is of note that the DPDK project is in a financially sound position to see 2020 through, under the watchful gaze of the Governing Board’s Financial committee, chaired by Rashid Khan from Red Hat. 

The Governing Board reviewed and approved an updated 2020 budget including our anticipated 2020 expenses of $316k, deferring unused event allocations to our reserve fund, in anticipation of 2021 events and the Community Lab expansion. 

The Governing Board has noted the importance of member retention and recruitment, particularly in these uncertain times, with the formation of a Strategic Outreach working group, comprised of a sub-group of Governing Board members, tasked with ensuring the identity, focus, and charter of DPDK is clearly captured, published and communicated, along with a clear and compelling membership value proposition. 

Towards this end, the Governing Board in conjunction with the Technical Board, has spent the last month reviewing and updating the DPDK Charter, which has not seen any significant changes over the past 3 years. The edits will bring the Charter up to date and serve as a current reflection of the project as it is today.    

The DPDK Project has also launched a new project analytics dashboard, providing insights into development activity and contributions. We continue to be an active healthy community. Please try out the new tool. Let us know if you feel the data is accurate and reflects the community breadth of contributors.

Community Lab Expansion 

As Jim and Thomas shared in an earlier message to the community, we have been evaluating the value and role of the DPDK Community Lab, hosted at University of New Hampshire’s InterOperability Lab, (UNH IoL).  Upon the recommendations of the Technical Board, the lab continues to play a key role in regression testing. The Governing Board has approved up to $35,000 in additional investment to expand the test coverage and support provided to the community through the Community Lab. We anticipate increasing the depth and breadth of test cases available to the community.  

The Community Lab meets on a bi-weekly basis and is open to the DPDK community. We would encourage you to participate –  reach out to to be added to the meeting calendar invite.

DPDK Marketing Activities

The marketing working group has a new project whitepaper and companion video series, to be published in the coming month.  Keep an eye out for it!

In 2020, DPDK celebrates 10 years as an active open source project from its formative years at Intel. We have come a long way since then, becoming the world’s leading open source packet processing tool kit.  Stay tuned for a fun look back across the past 10 years. 

Expect to see some exciting things happening over the next couple months. Stay tuned for more! And please let us know if you would like more information on any of these topics.

Community Update from the DPDK Board & Tech Chairs

By Blog

Greetings DPDK Project Community:

 We hope you are managing okay and remaining safe and healthy as the coronavirus crisis has thrown the world into a frenzy.  While many of us are used to working remotely and using online collaborative tools, we are having to adapt to new circumstances at home. It’s hard on everyone.  

 The DPDK Governing Board, Technical Board, and Marketing Committee have been hard at work locking down our final 2020 budget, crafting plans around worldwide DPDK Summit events, and exploring hosting a broader data plane projects developer event.  However, upcoming public gatherings and events have been cancelled or postponed and are no longer an option in the near term. DPDK has not yet migrated to virtual events. For now, our plans around DPDK Summit events are in flux:

  •  China and Japan events are on hold. As things develop further we will see if we can make something happen, perhaps in Q3 or Q4. 
  • The US DPDK Summit event is  pushed out to Q1 of 2021. The team made this decision before the pandemic emerged in order to create some  calendar space between the Summit and Userspace events. We have targeted the second half of September for the Userspace event, continuing to host it in Bordeaux.  As of now this is still our intent. But as we’re sure you can understand, the situation remains fluid until the pandemic subsides. Please bear with us.

 We have also continued to explore options to increase the value and role of the DPDK Community Lab that is currently hosted at the University of New Hampshire, InterOperability Lab, also known as UNH/IoL. We’d like to acknowledge Lincoln Lavoie and team’s continued efforts here, especially as he remains in the lab to triage hardware issues. However, we’ve struggled to find community volunteers to step up and lead the lab effort.  We are now looking at alternatives including a minimum set of activities and regression tests that the Technical Board recommends we maintain. Other efforts to expand the use of the lab will likely require additional budget. We are trying to converge on a solution. Help is still welcome should anyone want to get more involved.

The community continues to be amazing.  This year we’ve delivered our 20.02 release with few time accommodations.  Work is underway for the 20.05 release with several new features and improvements. 20.08 and 20.11 will follow.  We are confident the community collaboration and execution capability will serve us well during these times.  We are not expecting too much delay in releases. Of note, while most git maintainers do have a back-up in place, please let us know if you are able to help fill in any gaps. 

Overall we want to ensure you prioritize yourself and your family; your personal health and safety are paramount to us. Rest assured the DPDK community is here for you – whether it be  help on a features, code, or guidance on how to handle a challenging home dilemma, please do reach out. The DPDK family is strong and tremendously supportive. We are glad to be part of it.

Stay safe and healthy.

All the best,

Thomas and Jim
