a few days ago the launch of the new version of project Coreboot 25.06In this release, the team has integrated 879 changes contributed by 128 developers, including expanded motherboard support, new CPU architectures, power management improvements, and verified boot enhancements.
An of the most notable additions in Coreboot 25.06 is support for 5th generation Intel Xeon processors, Emerald Rapids, which opens the door to using Coreboot on the latest high-performance server and workstation platforms. It has also Expanded support for Qualcomm Snapdragon X Plus X1P-42-100 and the MediaTek MT8189 and MT8196 SoCs.
El Support for new motherboards has also grown Notably, among the most notable integrations are models from ASUS, Star Labs, System76, Siemens, and NovaCustom, as well as a large number of boards used in Chrome OS devices and Google servers.
A more powerful visual start
The infrastructure of The splash screen display has been completely revamped.. Now allows you to represent custom logoss, display additional information such as footers, and manage horizontal alignment. This change offers more freedom to manufacturers and users to personalize the startup experience, as well as incorporating useful features such as automatic low battery notification during startup.
Screen rendering end tracking has also been improved, ensuring a smoother transition between boot phases and operating system loading.
In addition, the tool cbfstool, responsible for managing the Coreboot File System (CBFS), now includes support for multi-ELF uploads, allowing group multiple executable binaries into a single entrya. This is especially useful for deployments that require TEE (Trusted Execution Environment) components or compartmentalized boots, typical in security-first environments.
Reduction of energy consumption
Coreboot 25.06 implements advanced features of Power management for Wi-Fi and Bluetooth through DSM PRR (Power Reduction Request). This allow that operating systems activate low-power modes when the wireless interfaces are not in use, aligning with Microsoft standards for Modern Standby. This results in improved energy efficiency for laptops and other mobile devices.
Verified boot security
The verified starting system (vboot) now backs up CMOS data during the final stages of startup. This enhancement protects the integrity of key configurations against potential power failures or initialization errors. Additionally, The VBOOT_EC_SYNC_ESOL option was introduced, which improves synchronization with integrated controllers, adapting to platforms with specific boot requirements.
The Coreboot build system has been updated to be fully compatible with GCC 15, Resolving new warnings and adapting to the latest changes of the compiler. Additionally, the crossgcc build environment now supports RISC-V ISA instructions, expanding the development possibilities for this emerging architecture.
Management of submodules and third-party libraries has also been improved., making it easier to track changes and ensuring a more reliable and reproducible build.
New policies on the use of AI tools
In this version, Coreboot has updated its documentation to board explicitly the use of artificial intelligence tools in code developmentThe new policy establishes that contributors must be fully responsible for the code they contribute, ensuring its quality, legality, and compliance with project licenses. The goal is to preserve the integrity of the software and avoid potential legal disputes regarding intellectual property.
Other important advances
Other relevant changes include:
- Improved support for memory initialization on Intel platforms.
- Improvements to SPI, ELOG, and SMMSTORE drivers.
- Extended support for the Resizable BAR feature for modern GPUs.
- Integration of technical documentation for devicetree, cbmem, and more.
- Additionally, libpayload, the set of libraries for payloads, received important fixes for ARM64 systems, as well as improvements to USB storage support and the build chain.
On the other hand, it is worth mentioning that the project continues to consolidate its community. To encourage global participation, A new biweekly meeting has been created at a more accessible time for collaborators in Asia. Furthermore, after years of waiting, Coreboot officially introduced its mascot: Blitz, a swift European hare that symbolizes the speed of the start and the adaptability of the project.
Finally, it's worth mentioning that the next release, Coreboot 25.09, is scheduled for release in late September 2025.
