AMD AGESA Firmware To Be Replaced By openSIL For Future CPUs Across Client & Server Platforms

wccftech.com:

AMD is working to replace its existing AGESA Firmware with a more open-source implementation known as openSIL which will support both client & server chips.

During the OCP Regional Summit held in Prague last month, AMD hosted its openSIL presentation where it talked about replacing the current AGESA implementation. The implementation will work across AMD's client & server chips which is great news as it was previously expected that only the server "EPYC" chips would get the openSIL treatment.

The AMD openSIL project is an open-source firmware solution that like the existing AGESA BIOS firmware allows the platform to work with different CPU architectures, memory subsystems, the DRAM, and a host of other utilities. Each AGESA firmware adds or removes certain things, but it's mostly used to expand upon the processors and platform capabilities.

For example, AMD AGESA firmware is currently a hot topic given the recent burnout issues and the necessary code is being put in place with upcoming firmware that will mitigate and correct the flaws within the processor's architecture such as adjusting voltages across different rails or making sure that EXPO runs fine.

Moving forward, AMD wants to go open-source and replace the AGESA firmware implementation entirely since openSIL will offer:

While the initial support for openSIL will be delivered to the 4th Gen EPYC CPU family known as Genoa / Bergamo, the firmware will also come to client chips starting in 2026. AMD expects first openSIL firmware's to go into production around 2026 which is about the time we get the Zen 6 core architecture which is codenamed "Morpheus". The openSIL firmware will land on both the client desktop and client mobility side.
