It officially closes the merge window for this release while you test. + +### Why 6.0? + +Usually, the mainline Kernel version increases by the minor version and this release should have been Kernel 5.20. However, Linus decided to increase the significant version number, hence the Kernel 6.0. + +> Despite the major number change, there’s nothing fundamentally different about this release – I’ve long eschewed the notion that major numbers are meaningful, and the only reason for a “hierarchical” numbering system is to make the numbers easier to remember and distinguish. Which is why when the minor number gets to around 20 I prefer to just increment the major number instead and reset to something smaller. + +Let’s take a look at what’s in store. + +### Linux Kernel 6.0 RC1 – New Features + +#### Processors + +AMD Zen systems gets a [performance boost][4] with updated NUMA balancing in the Kernel scheduler. + +The Ratbleed speculative execution exploits fixing [continues][5] in this release affecting Intel 8th Gen+ and AMD Zen 1+ CPU family. Although the Ratbleed has not yet been found in the wild (only in Lab), the fix continues in this Kernel. + +Lenovo and AMD [bring][6] the Automatic Mode Transition (AMT) support for Ryzen power ThinkPad laptops. This feature should give firmware-based power handling in those laptops with better efficiency. + +New audio hardware [support][7] for AMD Ryzen 7000 desktop processors (Raphael) lands in this release with ACP 6.x support. + +AMD is [preparing][8] for the release day with additional Instruction based sampling support for the Zen 4 series. + +More CPU [temperature monitoring code][9] lands for AMD 17th and 19th family of models. + +Initial work starts landing for Lenovo’s ARM Laptop X13 featuring Qualcomm Snapdragon 8cx Gen3 (SC8280XP) CPU. + +Likewise, in all releases, a bunch of SOC chips get support in Linux Kernel 6. The most notable ones include NXP i.MX93 SoC (primarily used for smart devices in home solutions). + +Here’s a quick list (not complete) of the SOCs that gets [support][10] in this instalment. + +* Broadcom SOCs for broadband devices * BCM63178 * BCM63158 * BCM4912 * BCM6858 * BCM6878 * BCM6846 * BCM63146 * BCM6856 * BCM6855 * BCM6756 * BCM63148 * BCM6813 +* Allwinner’s H616 (IPTV, OTT streaming) +* Marvell Prestera 98DX2530 +* Google Chameleon v3 FPGA + +In addition, a bunch of RISC-V processor code was introduced with an aim to support it in future. + +#### GPU + +Work continues in this Kernel release for Intel DG2/Alchemist and AMD RDNA3 graphics cards; the support is entirely not there but is in progress for future versions. + +A bunch of frame buffer device driver [update][11] (mostly fixes) arrives for Atari GPUs. Most noteworthy are the patchsets to fix VGA modes, colour handling and numerous code clean-ups. + +Intel Meteor Lake GPU [support][12] is starting up in this release. + +#### Storage and file systems + +Like all releases, the famous and supported file systems are updated and improved. + +Since the usage of SSDs is increasing, the flash-friendly file system (F2FS) [enhances][13] memory handling, garbage collection optimization and more. + +One Microsoft employee provides a [patch][14] to improve locking performance & reliability for CIF/SMB3 protocol to improve multi-channel operation over the network. + +#### Additional Changes + +Other noteworthy changes across this Kernel release include early work for Wi-Fi 7 support, more feature updates on the ongoing random number generation and setting up system hostname via Kernel parameter. + +Furthermore, one of the vital features is the “Run-Time Verification” codebase which helps Linux run in safety-critical infrastructure. The method takes an approach where the system specification instruction set is compared against the actual execution instruction set by re-implementing instruction sets at run-time. This is based on a paper which you can read [here][15]. The actual patch is present on this [page][16]. + +### Download + +You can download the source tree from the following page: + +| - | - | - | - | - | +| :- | :- | :- | :- | :- | +| mainline: | 6.0-rc1 | [tarball] | [patch] | [browse] | + +If you are running benchmarks, testing new hardware and finding issues, report to the Kernel mailing list. + +The Linux Kernel 6.0 is expected to be released by the beginning of Q4 2022, i.e. October timeframe. Hence, Ubuntu 22.10 may get this version (although I am doubtful about that). + +-------------------------------------------------------------------------------- + +via: https://www.debugpoint.com/linux-kernel-6-0-rc1/ + +作者：[Arindam][a] +选题：[lkxed][b] +译者：[译者ID](https://github.com/译者ID) +校对：[校对者ID](https://github.com/校对者ID) + +本文由 [LCTT](https://github.com/LCTT/TranslateProject) 原创编译，[Linux中国](https://linux.cn/) 荣誉推出 + +[a]: https://www.debugpoint.com/author/admin1/ +[b]: https://github.com/lkxed +[1]: https://www.debugpoint.com/wp-content/uploads/2022/08/kernel6rc1.jpg +[2]: https://www.debugpoint.com/2022/05/linux-kernel-5-18/ +[3]: https://lore.kernel.org/lkml/CAHk-=wgRFjPHV-Y_eKP9wQMLFDgG+dEUHiv5wC17OQHsG5z7BA@mail.gmail.com/T/#u +[4]: https://lore.kernel.org/lkml/Yufc5Mq1aqLVV%2FOv@gmail.com/T/#u +[5]: https://lore.kernel.org/lkml/Yvd%2Fg8RODN%2FpSkCX@gmail.com/T/#u +[6]: https://lore.kernel.org/lkml/19d29009-ab84-fffc-82dd-9754e65b092e@redhat.com/ +[7]: https://www.phoronix.com/news/AMD-Raphael-Audio-Driver-Linux +[8]: https://lkml.org/lkml/2022/8/4/694 +[9]: https://lore.kernel.org/lkml/Yue6jQd37wpssGeZ@zn.tnic/ +[10]: https://lore.kernel.org/linux-arm-kernel/CAK8P3a1DVcc=AV29AJJxMzBVoU-grFaNet0ndxPgPFvpK-ZANQ@mail.gmail.com/T/ +[11]: https://lore.kernel.org/lkml/Yu7J2Yj6UyAiE2Ne@ls3530/ +[12]: https://lists.freedesktop.org/archives/dri-devel/2022-July/364441.html +[13]: https://lore.kernel.org/lkml/YvE6fO1r0znOdr60@google.com/ +[14]: https://lore.kernel.org/lkml/CAH2r5mvaTWyWnPpYk=OPCbud85LEo5Oj=K2ZK56jmri6452zRQ@mail.gmail.com/ +[15]: https://dl.acm.org/doi/abs/10.1007/978-3-030-30446-1_17 +[16]: https://lore.kernel.org/lkml/20220803112014.7ffed04e@gandalf.local.home/
