AMD has confirmed that its upcoming Ryzen “Medusa” and EPYC “Venice” processors, based on the Zen 6 architecture, will include support for openSIL (Open Silicon Initialization Library) — an open firmware solution that will replace the traditional AGESA.
A Step Toward Open and Transparent Firmware
Presented at the OCP Summit 2025, openSIL represents a move toward greater transparency and modularity in silicon initialization.
This library is written in C-17 and divided into three components: Silicon, Platform, and Utilities.
Its design allows easy and scalable integration with any x86 host firmware, making adoption simpler for both client and server platforms.
According to AMD’s roadmap, EPYC Venice will debut in 2026, followed by Ryzen Medusa in the first half of 2027.
Both chips will come with openSIL from launch, marking the beginning of a new era of open firmware for the company and replacing AGESA.
A New Era for AMD and Open Firmware
The move to openSIL aims not only to improve firmware security and reliability but also to encourage collaboration with the open-source community.
AMD has reaffirmed its commitment to this initiative since its first announcement in 2023, continuously sharing updates at events like the OCP Global Summit. Now, there is a concrete roadmap for when the implementation will begin.
This decision positions AMD as a pioneer in adopting open firmware in the x86 processor sector. With Zen 6 and openSIL, AMD is not just pursuing performance — it’s also embracing openness and trust from developers.
