![]() ![]() Plus, as you can imagine, a whole lot more. Kernel support for NVMe in-band authentication.Other assorted changes in Linux 6.0 include: These make it possible to get or set the UUID stored in a filesystem superblock. Ubuntu’s default file system remains ext4, so I wanted to mention that Linux 6.0 enables two new ioctl() operations: EXT4_IOC_GETFSUUID and EXT4_IC_SETFSUUID. New hardware supported includes XP-PEN Deco L drawing tablet, a swathe of sensors on AMD motherboards, including Sensor Fusion Hub support on newer Ryzen laptops, and functional Thunderbolt on Intel Raptor Lake. Talking of laptops Linux enthusiasts use, some TUXEDO Computers and Clevo laptops had issues with touchpads and keyboard when resuming from suspend in earlier kernel versions. The ThinkPad X13s is pre-loaded with Windows 11 for ARM but, with Linux support now in the formative stages, this could be a great reference device for Linux ARM enthusiasts. The (expensive) Lenovo ThinkPad X13s laptop, which runs on the Qualcomm Snapdragon 8cx Gen3, starts to pick up support. RISC-V also ships with a new default configuration capable of running Docker from the get-go. Those noticing keyboard issues on Ryzen 6000 series laptop should, if using Linux 6.0, find things once-again function as expected.īoth the OpenRISC and LoongArch architectures gain support for PCI buses, while RISC-V buffs up its cache block management capabilities using a number of new extensions, including the “Zicbom” extension. This include support for Intel’s fourth generation Xeon server chips “Sapphire Rapids”, and their 13th generation “Raptor Lake” core chips.ĪMD provides a kernel graphics driver for their RDNA 3 GPU, land a new audio driver for AMD ‘Raphael’ platforms and improve the audio support for AMD ‘Jadeite’ systems. Linux 6.0 also does some mandatory future-proofing by laying groundwork for swathes of upcoming hardware. Seeing Linux squeeze more power while using less power is always a welcome one. Since two years is not long enough for the manufacturers to bring support for their hardware and software features, you’ll often find some LTS kernels to be supported for six years.Benchmarking done by Phoronix reveals appreciable performance improvements across Intel Xeon ‘Ice Lake’, AMD Ryzen ‘Threadripper’, and AMD EPYC processors thanks to scheduler changes and other kernel energy tweaks. This often happens for the Android projects. The agreement is done based on the necessity and the players involved. The maintainer of a LTS kernel may agree to maintain a certain LTS kernel for longer than the usual period of two years. But again, there is no set rules here as well. Usually, there is one LTS kernel release every year, usually the last release of the year and it is supported for at least two years. There is no set release schedule for LTS kernel as well. The LTS Kernel: How long is it supported? There are LTS (long term support) kernel versions as well and they are supported for a much longer period than just 3 months. This is applicable to the normal stable kernel versions only. Users and contributors are asked to switch to the newly released stable version. The end of support is announced by the maintainer of that particular stable kernel version in the Linux kernel mailing list. Like the release, there is no fixed dates and schedule for how long a kernel version will be supported.Ī regular stable kernel release is usually supported for two and a half months to three months, depending on the release of the next stable kernel release.įor example, stable kernel 5.14 would reach end of life a couple of weeks after the release of stable kernel 5.15. While X.Y is (often) released by Linux creator Linus Torvalds, the responsibility to maintain the stable X.Y kernel, merge bug fixes and release X.Y.Z versions is handled by a kernel developer. These small releases add one more point to the stable kernel to make it like X.Y.Z. The stable release gets further smaller releases to accommodate bug fixes. ![]() The release is declared ‘stable’ and is usually numbered in the format of X.Y.īut this is not the end of X.Y development. This typically happens every 2 to 3 months. That’s what the kernel maintainer team targets but there is no set deadline that the new version has to be released exactly 8 weeks from the previous release.Ī new kernel version is released (often) by Linus Torvalds when it is ready. What it means is that you’ll often see a new kernel version release every two to three months. The long answer is that it’s not a hard and fast rule. The short answer is that a new kernel version is release every two to three months. ![]()
