Going together with AMD’s work on AMD openSIL for open-sourcing the CPU silicon initialization code to in the end exchange AGESA in future {hardware} platforms, the preliminary EPYC “Genoa” code for Coreboot has been upstreamed together with the Onyx motherboard goal.
AMD openSIL initially helps EPYC 9004 “Genoa” processors and the preliminary motherboard supported by it occurs to be their Onyx reference motherboard. So it is fascinating to see the AMD Onyx reference motherboard additionally being the primary Genoa board supported by Coreboot and never their extra widespread Titanite 2P reference design.
This commit added the preliminary “minimal viable code for compilation” of the AMD Genoa SoC goal. Following that was additionally including the minimal implementation of the AMD Onyx motherboard.
That is simply the beginning of the AMD 4th Gen EPYC “Genoa” enablement for Coreboot with this work being performed each by AMD engineers and the 9elements safety consulting agency. There’s additionally much more Genoa code beneath assessment for Coreboot.
