Linux 6.0-rc1 released: improve the new hardware support performance optimization

After a two-week merge window, Linus Torvalds finally released the first "release candidate" (rc1) version of the Linux 6.0 mainline kernel in time for Sunday afternoon. For the next two months or so, the team will focus on stability improvements to the Linux 6.0 kernel. However, early testing of Phoronix shows that it is already performing quite well on a wide range of systems, with no slowdowns in functionality or performance.

Phoronix points out that Linux 6.0 rc1 has huge performance gains on high-end platforms such as Intel Xeon / AMD EPYC servers and Threadripper.

Linus Torvalds is said to have given the release the interesting "Hurr durr I'ma ninja sloth" moniker. Also in the coming weeks, Michael Larabel plans to start testing on more desktops/laptops.

Overview

● Linux 6.0 continues to add drivers for Intel Gen 13 Raptor Lake, new RISC-V extensions, and support for setting the system hostname via the hostname= kernel parameter.

● Support for AMD Auto Mode Switching on Lenovo ThinkPad laptops, Intel Habana Labs' Gaudi2 accelerator card, and a stable HEVC / H.265 interface.

● Audio drivers for the Zen 4 Riptide Raphael processor, some early support work for Intel's 14th generation Meteor Lake.

● For example, AMD Zen 4 IBS performance tools, Intel IPI/ KVM virtualization, AMD x2AVIC and Intel SGX2 support, and runtime validation for safety-critical systems.

● There is also a v2 version of the Btrfs send protocol, large scheduler enhancements, more AMD Zen 4 readiness work, continued AMD RDNA3 graphics support, and some excellent IO_uring improvements.

As a big update, Linux 6.0 added over a million lines of code during the cycle -- consuming a lot of work effort around new AMDGPU products and Intel Habana Labs Gaudi2 support for automatic header file generation.

By comparison, the Linux 5.19 merge window contained only 789,000 lines of new code, which means Linux 6.0 is much more powerful.

Even so, Linux 6.0 has yet to complete some feature merges this past weekend.

In addition to features such as the Rust patch, MGLRU performance enhancements and Maple Tree, the PREEMPT_RT real-time patch is also fairly close to the finish line.

Finally, Linus Torvalds notes some recent reports of Linux kernel crashes, and knows that the problem is mainly due to the VirtIO merge, which is currently being fixed, so hopefully the next week of work on Linux 6.0-rc2 will go smoothly.
