At the OCP Regional Summit, AMD invited all parties capable of participating in its open source firmware project and to use it freely also on their own platforms.
AMD has said at the OCP Regional Summit that it plans to replace the current AGESA firmware with a new architecture. The new firmware would obey the name openSIL, i.e. Open-Source Silicon Initialization Library and, as the name suggests, would be open source code.
AMD’s current AGESA is designed to work primarily with the UEFI interface, although some level of support for CoreBoot also exists. However, support for alternative firmware interfaces has been weak in many respects, and in particular, concerns about compromising the information security processor (PSP, Platform Security Processor) of the company’s processors have been effective brakes on the continuation of development.
However, AGESA’s days are numbered, as AMD’s chief firmware architect Raj Kapoor also stated during the presentation’s question session. It will be replaced by openSIL firmware built from three libraries. OpenSIL is an interface-independent, easily scalable package written with C17, the latest standardized version of the C language, which, as an open source code, can also be freely used and modified by other parties. In its presentation, AMD invited all companies that manufacture silicon chips to participate in the development workshops and believes that crowd power will improve the security of the firmware.
According to AMD, the development of openSIL started at the beginning of last year and its development arc is divided into four phases. The project has reached its first milestone and the Proof-of-Concept implementation designed for Genoa processors is now operational, according to AnandTech. However, it is planned to be ready only in 2026, when it would replace AGESA in all the company’s new processors. At the current rate, we are probably talking about Zen 6 or Zen 7 processors, and it would not be far-fetched that the processor bases would also change to new ones for the same reason; currently AMD has promised support for AM5 until at least 2025. On the server side, the change is expected to happen apparently for the 6th generation Epycie.
