Linus Torvalds has introduced the secure launch of Linux 6.0 however flagged it does not include the “core new issues” coming in Linux 6.1. 

Because the first launch candidate (rc1) for Linux 6.0 in August, Torvalds has performed down the which means of the main model quantity change, which might have in any other case been 5.20. Whereas has known as 6.0 a “pretty sizable launch”, he additionally mentioned at convention final month “I needed 6.0 to be boring.” 

 As he wrote on Sunday in an replace: “So, as is hopefully clear to everyone, the main model quantity change is extra about me working out of fingers and toes than it’s about any massive basic modifications.”    

As famous by Phoronix in the course of the 6.0 merge window, Linux 6.0 brings efficiency enhancements for Intel’s Ice Lake Xeon processors in addition to AMD’s Ryzen Threadripper and AMD EPYC. 

There’s additionally new {hardware} assist for Intel’s Sapphire Rapids, Raptor Lake, and Meteor Lake processors, and new {hardware} assist for Qualcomm’s Snapdragon 8cx Gen3. Linux 6.0 advances RISC-V assist on a number of fronts whereas there have been {hardware} updates for OpenRISC and Chinese language LoongArch.   

“However after all there’s a number of varied modifications in 6.0 – we have over 15k non-merge commits in there in whole, in any case, and as such 6.0 is among the larger releases not less than in numbers of commits shortly,” famous Torvalds.

The massive information about Linux 6.1 and prone to be among the many “core new issues” Torvalds mentions is the addition of the Rust programming language to the Linux kernel, permitting builders to construct issues like drivers and different parts in Rust as an alternative of defaulting to the C programming language.  

Additionally: It is time to cease utilizing C and C++ for brand spanking new tasks, says Microsoft Azure CTO

“And this clearly implies that tomorrow I will open the merge window for six.1. Which – not like 6.0 – has plenty of pretty core new issues lined up. However for now, please do give this most up-to-date kernel model a whirl,” wrote Torvalds on the Sunday mailing checklist. 

Through Phoronix, a pull request for bringing Rust language assist into Linux 6.1 was submitted to Torvalds on Saturday by kernel developer Kees Cook dinner and Miguel Ojeda, the developer driving the Rust for Linux mission.

Kees wrote to Torvalds requesting he pull the “Rust introduction” pull request, whose contents include “absolutely the minimal to get Rust code constructing within the kernel”. Many extra interfaces and drivers are within the works, Kees famous. 

Preliminary assist is available in 4 classes, protecting: kernel internals; ‘Kbuild’ Linux construct infrastructure corresponding to Rust construct guidelines and assist scripts; the Rust ‘Crates’ packages and bindings; and Rust kernel documentation and pattern. 

Moreover being higher than Linux’s incumbent C language at reminiscence safety, Torvalds’ additionally sees Rust as a option to appeal to new builders. 

“Rust is a type of issues that I believe would possibly usher in new faces,” Torvalds mentioned just lately, including that, “We’re getting previous and grey.” Torvalds mentioned on this first launch, Rust will “simply have the core infrastructure (i.e. no severe use case but).”
