Last year open-source developers called on Intel to open-source their "PSE" firmware. The Programmable Services Engine (PSE) introduced with Elkhart Lake is an Arm Cortex-M7 companion core responsible for various tasks and is programmed by a binary-only firmware module. While it started out as a proprietary, binary blob, the PSE firmware has now been open-sourced!..
