In addition to [1]talking up the openSFI firmware collaboration between AMD and Intel at the OCP Global Summit 2025, AMD engineer Raj Kapoor provided a status update on the company's much anticipated [2]openSIL effort for working to ultimately replace AGESA with a new open-source CPU silicon initialization codebase.

AMD openSIL updates at Open Compute Project events have sort of become an annual tradition since [3]openSIL was announced back in early 2023 at the OCP Prague event. At the recent OCP Global Summit in San Jose was the latest update on openSIL and those slides / video recordings are now available.

AMD continues investing in open-source firmware for greater trust and transparency. With the hyperscalers it can mean easier customization as well as faster integration and all around a growing industry interest in open-source firmware by the hyperscalers like those involved with OCP.

AMD did release the openSIL Firmware Architecture Specification "FAS" 1.0 release as part of the OCP efforts. This is a public document with all the technical firmware specifications around openSIL to aide developers.

AMD also recently [7]published the long-awaited openSIL code for Phoenix SoCs . The AMD openSIL presentation also reaffirmed plans for 6th Gen AMD EPYC "Venice" with openSIL. They plan to open-source their Venice openSIL code around one quarter after those 6th Gen EPYC CPUs ship. They say that open-source will be in 2026, so that would mean Venice is launching in Q3 or earlier. Meanwhile the AMD Ryzen Zen 6 "Medusa" openSIL code will come in the first half of 2027.

They will be continuing with initially NDA'ed openSIL code prior to hardware launches and then open-sourcing new platform code after the fact.

[9]

Public pull requests will be permitted to openSIL for properly evaluated changes.
