At Open Source Summit North America 2025 (Denver, CO, June 23–25, 2025), Kyle Swenson of Ericsson will present new upstream Linux kernel support for the LTC4266, the last major Power Sourcing Equipment (PSE) chipset to be integrated. This work builds on PoE controller support funded by the DENT project, which enabled upstream drivers for the Microchip and TI chipsets. The talk will walk through the fundamentals of PoE, the in-kernel framework, user-space control interface, and the specifics of the new LTC4266 driver, marking an important milestone in building out comprehensive PoE support in Linux networking.
