The latest release of the Linux Kernel, version 6.12 RC1, has been announced with some exciting new features. Perhaps the most noteworthy addition in this release is the mainlining of the PREEMPT_RT patch, as well as the merging of the Sched_ext patch. These enhancements are set to significantly improve real-time capabilities in the Linux Kernel, making it even more attractive for use in mission-critical applications.

The PREEMPT_RT patch, short for Preemptible Real-Time, aims to reduce the latency in the kernel by allowing tasks to be preempted at any time, resulting in more responsive real-time performance. Previously, users had to apply this patch separately, but with its mainlining in version 6.12 RC1, it is now included in the mainline kernel by default. This move will make it easier for users to take advantage of the real-time capabilities of the Linux Kernel without the need for additional patches.

In addition to the mainlining of the PREEMPT_RT patch, the Sched_ext patch has also been merged in this release. This patch introduces a new scheduling class that aims to provide better support for modern hardware, particularly in cases where the traditional scheduling mechanisms may not be optimal. By merging the Sched_ext patch, the Linux Kernel is now equipped with improved scheduling capabilities, enabling it to better utilize the resources of modern hardware and improve overall performance.

Overall, the inclusion of these patches in the Linux Kernel 6.12 RC1 signifies a significant step towards enhancing real-time capabilities and improving performance in the kernel. With these enhancements, the Linux Kernel is poised to become an even more attractive option for users who require real-time performance in their applications.

Users who are interested in trying out the new features in the Linux Kernel 6.12 RC1 can download the release candidate from the official Linux Kernel website and provide feedback to help improve the final release. As always, it is recommended to test the new features in a controlled environment before deploying them in production to ensure compatibility with existing systems and applications.

In conclusion, the release of Linux Kernel 6.12 RC1 with the mainlining of the PREEMPT_RT patch and merging of the Sched_ext patch represents a significant milestone in the development of the Linux Kernel. These enhancements are set to improve real-time capabilities and performance, making the kernel even more versatile and powerful for a wide range of applications.
