During the OCP Regional Summit, AMD revealed its plans to replace the AMD Generic Encapsulated Software Architecture (AGESA) with an open-source solution called Open-Source Silicon Initialization Library (openSIL). This is expected to happen by 2026 and will gradually cover AMD's entire product stack, including Ryzen and EPYC processors.

The first mentions of AMD openSIL go back to March when we learned it would support Coreboot and other firmware solutions. A month later, AMD finally started to spill the beans about the new firmware solution, stating that 4th Gen EPYC processors would support it. That made some wonder if openSIL would also be supported by Ryzen processors.

According to Phoronix, that sure seems to be the case. During the summit, Raj Kapoor, AMD Fellow and chief firmware architect, shared further details about AGESA's challenges, stating that “AMD openSIL will be scaling to both server and client platforms by the 2026 timeframe”. Kapoor then added that AGESA would be EOL and be replaced by openSIL.

Considering 2026 as the launch date of openSIL, we assume it won't be ready before the launch of Zen 6 or Zen 7 CPUs, at least for client platforms. Still, the PoC code for the AMD EPYC 7004 series server CPUs will be available soon. The gradual transition to openSIL is expected to take time, but at least AMD is committed to providing a more secure and efficient solution with the new open-source library.

KitGuru says: As an open-source technology, AMD's openSIL could benefit from community improvements and versions tailored to specific use cases.
