Linux Support for PoE Funded by DENT

By Blog, Community News, News

DENT has made significant strides in enhancing the upstream Linux Kernel to function as NoS without additional overheads for retail-edge use cases. A critical feature for these edge scenarios is Power over Ethernet (PoE). In this blog post, we will explore DENT’s contributions by examining past, present, and future PoE support in the upstream Linux Kernel.

Past Developments:

Previously, the Linux kernel offered no support for PoE technologies. Hardware vendors frequently provided non-universal, user-space solutions resulting in fragmented and inconsistent implementations. DENT recognized the need for evolution and began developing a standardized solution integrated within the Linux kernel.

In 2022, a major milestone was reached when a Power Sourcing Equipment (PSE) subsystem was added to the Linux kernel. However, this subsystem was only capable of supporting a related technology called Power over Data-Lines (PoDL). Learning and building from this achievement, DENT focused on implementing total PoE support.

Ongoing Developments:

DENT member Bootlin has spearheaded the development of DENT’s upstreaming efforts. Our initial goal was to bring basic PoE support, focusing on basic features like enabling and disabling power and achieving port status. This successful effort resulted in the development and upstreaming of drivers for two different PoE controllers: Microchip PD692x0 and TI TPS23881.

Bootlin’s Köry Maincent (Embedded Linux and Kernel Engineer) played a critical role in this development, spanning nine iterations from November 2023 to April 2024. The culmination of this work will be seen in the Linux 6.10 release, marking a significant achievement for DENT and the broader Linux community.

For more information on Maincent’s remarkable work, watch his presentation from Embedded Open Source Summit 2024.

Following the initial support, DENT immediately began working on the next set of features, including enhanced status information like consumed power, negotiated class and extended state reports, as well as the option to read and configure PoE port power limits. This work, developed through six iterations, has been merged and is set to be included in Linux 6.11.

What’s Next:

Looking ahead, DENT has ambitious plans for PoE. Next steps include:

  • Supporting port priority to manage power allocation when existing, available power is insufficient.
  • Implementing the PD62x0 persistent configuration mechanism for custom configurations across reboots.
  • Modifying the POED project to use the new standard Linux interface for PoE instead of user-space drivers.

DENT is committed to further enhancing PoE support within the Linux kernel. Stay tuned as DENT continues to build a brighter future for open source PoE.

Further, the DENT Community presented two sessions at the event. Taskin Ucpinar, Senior Technical Program Manager at Amazon, discussed DENT’s Features Roadmap for Disaggregated Enterprise Networks. Ucpinar explained how the DENT community envisions unifying the community of Silicon Vendors, ODMs, SI, and OEMs to provide and enhance Distributed Enterprise Edge functionality, enable wider adaptation of disaggregated enterprise networks, and cover expanded use cases.

Then, Taras Choryni, PLVision’s Director of Open Networking Solutions and Strategy, spoke about the SAI Virtual Switch in DentOS. In his presentation, Chornyi explained the experience of using the SONiC SAI Virtual Switch in DentOS. Throughout the development and testing phases of NOS, DENT leverages virtualization to simulate a streamlined yet authentic data center switch environment. This approach allows comprehensive testing of the control plane applications without the need for physical hardware. By enabling the virtual switch, users gain the power to emulate multiple switches in complex networking setups in virtual environments. This offers businesses the flexibility to streamline their development and testing even before a fully deployed physical device is available. 

Videos of both sessions will be available soon.
