One of the AMD software initiatives we have been most excited about in recent times has been openSIL. AMD openSIL is working toward open-source CPU silicon initialization that will jive better with the likes of Coreboot and ultimately replace their existing AGESA implementation. AMD openSIL is expected to span AMD’s wide gamut of processors from client/embedded through server offerings. It’s still looking to be on track for production readiness in 2026.
We haven’t heard much news on AMD openSIL in recent times and no major code since the openSIL proof-of-concept for EPYC 9005 “Turin” was published earlier this year.
The Genoa proof-of-concept code branch for AMD openSIL hasn’t been touched since last year but for that Turin proof-of-concept code there was a recent README update.
Committed on 20 August was updating the AMD openSIL README that the production phase will be ready in “2026” as opposed to the prior “EOY 2026 or early 2027.”
The 2026 readiness is what we had been expecting for a while. They have been aiming for production readiness with AMD Zen 6 platforms in 2026. So it’s looking like that is still on even with not much public news recently for this software project. Here’s to hoping that Zen 6 and AMD openSIL is ready earlier in 2026 than later, which may be the case given this slight README update.
