DPDK on RISC-V - Stanislaw Kardach, Semihalf
DPDK runs on a variety of platforms. When a new CPU architecture emerges, it's a question of "when" rather than "if" DPDK will be ported to it. As more high performance cores enter the market, the answer to that question for RISC-V is "now". This talk is a short story of a first RISC-V DPDK porting attempt and what came out of it. This includes a working demo on one of the available hardware platforms, description of challenges faced during the project as well as the current state and the future of the port.

Getting Past Incubation: DPDK for Windows Platform Goes Mainstream - Harini Ramakrishnan, Microsoft; Pallavi Kadam, Intel; Tal Shnaiderman & Dmitry Kozlyuk, NVIDIA
The Windows networking stack is evolving to meet the insatiable demands of today's workloads. DPDK is at the crux of this transformation towards building a predictable, high bandwidth, low latency networking data plane.   DPDK Windows platform support was first introduced in 2018 through  a disconnected POC. Ever since, significant effort has been made to integrate with upstream DPDK. Today, through community driven leadership, each new of release of DPDK can build and run successfully on Windows. In this presentation, we will review the Core Libraries, APIs, Device drivers and sample applications that are functional on Windows Platform. We will highlight learnings, challenges, improvements, and trade-offs made to retain cross-platform compatibility. We will share a preview of the roadmap and DPDK's role in accelerating the Windows Networking stack.

Using Virtual Functions with DPDK in OpenShift 4 - Ip Sam & Wuxin Zeng, Red Hat
OpenShift 4 has a big leap forward with new features coming from CoreOS. In OpenShift 4, it is possible to use the DPDK libraries and attach a network interface (virtual function) directly to the pod. DPDK libraries offers to free up the Kernel space from interrupts by processing the work in User space. To simplify the application building process, we can leverage Red Hat's DPDK builder image from the Red Hat registry. This base image allows developers to build applications powered by DPDK. In this meeting, we will go over the OpenShift Architecture, the DPDK libraries, DPDK poll mode driver (PMD), and show examples using  virtual functions with DPDK in OpenShift.

Running P4 programs as DPDK applications - Cristian Dumitrescu & Han Wang - Intel
This presentation provides a technical overview of the on-going work to enable the P4 language in DPDK. The P4-DPDK project unites the dpdk.org and p4.org communities to enable data plane programs in the P4 language to run as DPDK applications, with significant code contributions already integrated in DPDK since release 20.08.

Advanced API For Rules Management - RTE Flow Next Evolution - Ori Kam, NVIDIA
As more and more applications, such as Gateways, Security, routing, are starting to offload much of the SW actions to the HW, The RTE flow is becoming the goto solution.  But as the number of rules is increasing, so is the demand for high insertion rate and    multi-core scalability.  In this talk, I plan to show how we can multiply the insertion rate and allow multi-core scalability without breaking current DPDK applications.

Tools for Memory Model Simulation - Herd7 - Honnappa Nagarahalli, ARM
DPDK adopted C11 memory model in 20.08 release. One of the major issues the developers face with the C11 memory model is validating the correctness of the algorithms since it is difficult or impossible to write test cases for every possible race condition. Many programmers have resorted to rudimentary tools like memory order diagrams or their own understanding of the memory model. This often leads to code that seems to work but is incorrect from the C11 standard perspective. Hence, we need standard tools to validate the algorithms.  This presentation introduces one such tool - herd7. The presentation will take couple of algorithms from DPDK, show how to represent them in herd7, run the representation and interpret the output.  This tool will help the developers to create algorithms easily and quickly. This tool can also be used in review of future algorithms that are introduced in DPDK.

Using Zero-Copy Ring APIs to Improve Performance of DPDK Pipeline-Mode Applications - Dharmik Thakkar, Arm Inc.
DPDK supports pipeline-mode applications. These applications have packet I/O and packet processing stages. Software rings are used to transmit/receive packets between these stages. In this presentation, I will talk about using zero-copy ring APIs to improve the performance of pipeline mode applications. This presentation will highlight the challenges involved when using zero-copy ring APIs and present the solutions to overcome these challenges. I will also talk about the effect of various configuration parameters (zero-copy ring size, packet burst size, etc.) on throughput, memory bandwidth, cache eviction, and IPC.

Transitioning Flow Based ethdev Ops to rte_flow - Ajit Khaparde, Broadcom
Since its first release, DPDK has provided the ethdev API allowing applications to get/set NIC hardware. And we have added more to that over time. Then in the 17.02 release, came rte_flow API. Over the last few years rte_flow API has gone through a lot of enhancements. Eventually it deprecated the legacy filtering framework. In DPDK 20.11, we introduced the RTE_FLOW_ACTION_TYPE_SAMPLE action which deprecated the rte_eth_mirror_rule_set provided originally in the ethdev API. Likewise we have some more features in the rte_flow API which allow the DPDK applications to configure the underlying NIC hardware without calling the ethdev APIs. There are a few more candidates which could be potentially deprecated in lieu of using suitably crafted rte_flow calls.
