The Future of Linux: The Linux 5.9 Release, 5.8 Performance, Torvalds on Kernel Size

Linux 5.9 Likely To See USB4 Support Improvements
Linux 5.6 brought initial USB4 support that primarily was starting things off by basing things off the existing Thunderbolt 3 support in the kernel for which this latest USB standard is based. For the Linux 5.9 kernel later this summer it's looking like there will be further work on getting Linux's USB4 support into good shape ahead of hardware appearing in the months ahead.
Via the Thunderbolt bleeding-edge branch has been a number of USB4 patches building up over the past week. Intel's Mika Westerberg, Kranthi Kuntala, and Rajmohan Mani have been working on these latest USB4 additions.

Linux 5.8 Bringing Some Performance Boosts For AMD Renoir Graphics
Over the weekend I began running some benchmarks of the Linux 5.8 development kernel on the Lenovo Flex 5 laptop with Ryzen 5 4500U. One of the standouts so far for from this Linux 5.8 testing compared to the stable 5.6/5.7 kernel series is better Radeon graphics performance with the Renoir laptop.

Linus Torvalds on the future of Linux kernel developers and development
The illustrious pair started with Hohndel asking about the large size of the recent Linux kernel 5.8 initial release. Hohndel wondered if it might have been so big because developers were staying home thanks to the coronavirus. Torvalds, who always worked at home, said, "I suspect 5.8 might be [so large] because of people staying inside but it might also be, it's just happened that several different groups ended up coming at roughly the same time, with new features in 5.8."
While COVID-19 has slowed down many technologies, while speeding up other tech developments, it hasn't affected Linux development much at all. "None of my co-developers have been hugely impacted either. I was worried for a while because one of our developers was offline for a month or two. … [But,] it turned out that it was just RSI [repetitive strain injury], and RSI is kind of an occupational hazard to deal with." He added. "One of the things that is so interesting about the Linux community is how much it has always been email-based and remote, how rarely we get together in person."
In any case, Torvalds trusts this new build. Indeed, he ran his end of the videoconference from his new developer machine running the first release candidate of 5.8.

Samsung, Red Hat to Work on Linux Drivers for Future TechThe metaverse is expected to uproot system design as we know it, and Samsung is one of many hardware vendors re-imagining data center infrastructure in preparation for a parallel 3D world. Samsung is working on new memory technologies that provide faster bandwidth inside hardware for data to travel between CPUs, storage and other computing resources. The company also announced it was partnering with Red Hat to ensure these technologies have Linux compatibility. |
