[dpdk-dev] 17.11 Intel Roadmap

[O'Driscoll, Tim]

Below are the features that we're planning to submit for the 17.11 release. We'll submit a patch to update the roadmap page with this info.

It would be good if others are also willing to share their plans so that we can build up a complete picture of what's planned for 17.11 and make sure there's no duplication.


QoS Traffic Management Software Fallback and Sample App: The new QoS traffic management API (rte_tm) was added to ethdev in 17.08. A software fallback using the existing DPDK QoS scheduling library (librte_sched) will be added. A sample application will also be created which demonstrates usage of this API.

Extend Power Management Lib to Support Per-Core Turbo Boost: The power management library will be enhanced to support the ability to enable per-core turbo boost for CPUs that support this capability. An example usage of this would be in a pipeline model where enabling turbo boost on a distributor core will increase overall system performance without having to enable turbo on the worker cores.

Power Management Policy Control: This change will allow policy control to be applied to power management actions such as changes to p-states. A guest will be able to send policy info to a power management process on the host, which will apply that policy when making power management changes.

DES SW PMD: A new SW crypto PMD will be created to support DES. This will provide an optimized implementation for AVX512, and an unoptimised implementation for AVX2/AVX/SSE.

AES CCM Support in OpenSSL PMD: Support for AES CCM mode will be added to the OpenSSL PMD. Further details on AES CCM are available at: https://en.wikipedia.org/wiki/CCM_mode.

QAT PMD Performance Enhancements: Improve QAT cryptodev driver performance by 1) RX/TX CSR writes coalescing, 2) deferred freeing of RX descriptors, and 3) removing atomics and assuming single threaded queue pair operation.

Generic Segmentation Offload (GSO): Support for Generic Receive Offload (GRO) was added in 17.08. Similar support for GSO will be added in 17.11.

GRO Heavyweight Mode Sample App: The Generic Receive Offload library added in 17.08 operates in two modes: lightweight and heavyweight. Use of the lightweight mode is demonstrated with testpmd. A sample application will be created to demonstrate usage of the heavyweight mode.

Primary/Secondary Process Support for Virtual Devices: Most virtual devices don't currently support the primary/secondary process model. Support for this will be added.

Extend Port ID to 2 Bytes: The Port ID will be extended to 2 bytes. See the ABI deprecation notice for further details: http://www.dpdk.org/dev/patchwork/patch/26852/.

I40E API to Configure RSS Queue Regions: The I40E allows queue regions to be defined, so that different traffic classes or different packet classification types can be sent to different queues.
