Here’s a summary of key milestones over these last three years, including the most recent merging of ACRN patch sets into the Linux 5.12 kernel. Congratulations to the ACRN community, and Happy Birthday!

ACRN Hypervisor Release Version 2.4

By Blog

We are pleased to announce the release of ACRN™ hypervisor version 2.4.

What’s New in v2.4

Extensive work was done to redesign how ACRN configuration is handled, update the build process to use the new configuration system, and update the corresponding documentation. This is a significant change and improvement to how you configure ACRN but also impacts existing projects, as explained in the next section.

We’ve also validated the hybrid_rt scenario on the next generation of Intel® Core™ processors (codenamed Elkhart Lake) and enabled software SRAM and cache locking for real-time performance on Elkhart Lake.

See the v2.4 full release notes and documentation for more information about this release including fixed and known issues.

Happy 3rd Birthday, Project ACRN™!
