Linux 6.11 released
Linux 6.11 is now available. In his announcement, Linus Torvalds mentioned that the release was largely uneventful, with the majority of patches being relatively small and focused. Torvalds highlighted that the most prominent update in this release is the addition of Hyper-V Confidential Computing documentation.
Torvalds, who is currently on the road in Vienna, noted that while the merge window for the next release cycle opens tomorrow, progress might be slower than usual due to his participation in Open Source Summit Europe and the Kernel Maintainer Summit. He has over 40 pull requests pending but asks for patience as he works through them.
Linux 6.9-rc1 provides a glimpse into the future of the open source kernel
Linus Torvalds has officially announced the release of Linux 6.9-rc1, marking the end of the merge window for this version. As usual, the update brings a ton of changes, with a significant portion attributed to AMD GPU header files. But let's not get bogged down by the sheer volume of these updates; the real excitement lies in the core improvements that promise to enhance the kernel's performance.
Two major updates steal the spotlight in this release: the timer subsystem and the workqueue subsystem. The timer subsystem has undergone a substantial rewrite, introducing per-CPU timer wheels. This enhancement is poised to boost the performance of timers, which is especially crucial for networking operations. On the other hand, the workqueue subsystem now supports BH workqueue support, providing a much-needed alternative to the long-deprecated tasklet interface.
