Linux 6.13 has been released by Linus Torvalds, offering several new features and improvements to the stable kernel version. The update introduces lazy preemption support to simplify the kernel’s preemption logic, enabling better hardware support for various devices.
Key highlights of Linux 6.13 include:
* Lazy preemption support
* Support for running Linux in protected virtual machines (realm)
* User-space shadow stack support for AArch64 (ARM64) via Guarded Control Stack (GCS)
* Improved support for Intel and AMD CPUs
* Enhanced networking capabilities, including IRQ suspension and TX H/W shaping API
* Filesystem improvements, such as device aliasing in F2FS and basic support for atomic write operations in XFS
The update also brings new hardware drivers and supports various devices, including tablets, GPUs, and audio chips. Additionally, Linux 6.13 enables real-time computing capabilities on the LoongArch architecture and introduces support for pointer masking in userspace.
For those who want to compile Linux 6.13 from source, it is available for download from Linus Torvalds’ git tree or the kernel.org website. However, it’s recommended to wait for the new Linux release to arrive in your distro’s stable software repositories before updating your kernel.
The merge window for the next major kernel branch, Linux 6.14, is expected to open soon, with a first Release Candidate (RC) development version available for public testing in two weeks.
