Elkhart Lake processors integrate the Intel Programmable Services Engine (Intel PSE) offload engine for IoT workloads powered by an Arm Cortex-M7 microcontroller that handles real-time IO control using GPIO, I2C, and/or UART interfaces, and supports functions such as remote, out-of-band device management, network proxy, embedded controller, and sensor hub.
Until now the firmware was only provided as a closed-source binary, and Coreboot developers published an open letter to open the source code for the PSE firmware last December, and it’s been successful with Intel releasing the Intel PSE SDK based on Zephyr OS.
While the Intel PSE SDK is not entirely open-source, this may still help with integration into open-source bootloaders, alleviated some of the security/privacy concerns, and possibly enable some new use cases for the Intel Programmable Services Engine.
