About this tag
The opensil tag covers AMD’s open-source silicon-initialization and platform-firmware work as it develops around Dasharo and coreboot. Current coverage focuses on 3mdeb’s Dasharo v0.9.0 release for the MSI PRO B850-P WIFI, combining coreboot, AMD openSIL, and an EDK II UEFI payload. The firmware has been tested with Windows 11 25H2 on a Phoenix-based Ryzen 8000 desktop APU configuration, marking an important demonstration for open firmware on modern consumer hardware. Related updates track submitted changes intended to move the project toward upstream openSIL and coreboot, while noting that those patches remain under review and are not yet merged.
