Linux Kernel 6.12 has officially been released with real-time capabilities and more

Linus Torvalds has announced the release of the Linux kernel 6.12, introducing a variety of new features and enhancements, along with expanded hardware support. Key updates in this release include the ARM permission overlay extension and improved compile-time control for selecting Spectre mitigations. It also finalizes the real-time preemption support, introduces the real-time deadline server mechanism, and continues development on the EEVDF scheduler.

Additionally, the release presents an extensible scheduler class, advances in device memory TCP work, and the use of static calls within the security-module subsystem. A new integrity policy enforcement security module is also included, alongside support for handling devices with block sizes larger than the system page size within the XFS file system.

As Linux 6.12 stabilizes and likely becomes this year's LTS kernel, attention shifts to the Linux 6.13 merge window, anticipated to focus heavily on new features.
