You will notice improvements for the CPU and GPU as well. - -There are also some improvements for Raspberry Pi 4, and other ARM hardware/processors. - -Here are the key highlights of this release: - -#### Performance Boost for AMD-Powered Laptops - -As per some benchmark tests by [Phoronix][1], Linux Kernel 5.16 seems to give a performance uplift to laptops with Ryzen processors and Radeon graphics. - -If you are going the AMD way or already have a laptop with AMD CPU and GPU, you should more out of your laptop! - -I suggest you take a look at the benchmarks if you are curious about the exact figures and how it impacts the performance. - -#### Sony PlayStation 5 & Nintendo Switch Controller Support - -![][2] - -PlayStation 5 is undoubtedly one of the best-selling consoles (even if you can’t find one). - -Hoping that you got yours, Linux Kernel 5.16 improves the support for PlayStation controller with an update contributed by Sony. In case you’re curious, they added the official driver to the Linux Kernel last year with [Linux 5.12][3], so kudos to them! - -In addition to that, the open-source reverse-engineered driver for Switch Pro and Joy-Cons controller is finally joining the mainline with this release. - -#### Improvement for Windows Games Running on Linux - -If all goes well, Windows games run fine on Linux, however, there are some performance issues lurking. So, to match a specific functionality in Windows, FUTEX2’s **sys_futex_waitv()** system call is being added to Linux Kernel 5.16. - -It was being worked on for quite a while since last year. So, it is good to finally see it in the first week of 2022. - -Considering it will resemble the behavior of Windows interacting with games, Wine/Proton-powered games should get a performance boost. - -Even if it is by a small margin, it brings the Linux gaming experience closer to what you find with Windows, in terms of performance. - -#### Raspberry Pi Compute Module 4 Support - -A variant of the Raspberry Pi 4 series tailored for industrial and commercial applications is now supported with Linux Kernel 5.16. - -![][4] - -#### Display Port 2.0 Support - -While Display Port 2.0 is not meant for current-gen AMD cards, progress has been made to bring DP 2.0 support in the AMDGPU driver. This way, upcoming Linux Kernel releases should quickly adopt the latest standard if/when RX 7000 series GPU requires DP 2.0. - -#### Initial Work for Intel Raptor Lake - -Intel Raptor Lake will be the 13th Gen series of processors, due for release later in 2022. - -And, Linux Kernel 5.16 marks the early work for the Raptor Lake series, considering there are rumors for it to introduce a 24-core/32 thread variant. - -#### Ryzen 6000 Mobile Processor Support - -Initial work for AMD’s next-gen Ryzen 6000 mobile series (announced at CES 2022) is taking shape with Linux Kernel 5.16. - -#### Apple M1 Improvements & Apple Magic Keyboard - -The support for the Apple M1 chip is significantly improving with every kernel release. This time, you get additions for USB, PCIe, and a few minor fixes. - -In addition to that, you finally get to see the support for the Apple Magic keyboard in the mainline Linux Kernel. - -#### Connectivity Improvements - -With Linux Kernel 5.16, there are improvements to support low-latency USB audio. - -And, some vital work to support newer Realtek 802.1ax wireless adapters comes baked in with it. - -#### Other Improvements - -Some other notable additions include: - - * Snapdragon 690 support - * KVM RISC-V support - * AMD EPYC CPU KVM improvements - * Improved support for HP Omen laptops - * RISC-V kernel build enables open-source NVIDIA driver - - - -You can refer to the [official changelog][5] and [Linus Torvald’s announcement][6] to explore more details. - -### How to Install Linux Kernel 5.16? - -You should find the newer kernel listed on [Linux Kernel Archives][7]. So, you can download the [tarball][8] to test it out. You can follow our [Linux Kernel upgrade guide][9] for help. - -If you want to avoid compiling it yourself, you should wait for a few weeks for distributions to push it to the repositories. - --------------------------------------------------------------------------------- - -via: https://news.itsfoss.com/linux-kernel-5-16/ - -作者：[Ankush Das][a] -选题：[lujun9972][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://news.itsfoss.com/author/ankush/ -[b]: https://github.com/lujun9972 -[1]: https://www.phoronix.com/scan.php?page=article&item=linux516-amd-apus&num=1 -[2]: data:image/svg+xml;base64,PHN2ZyBoZWlnaHQ9IjQzOSIgd2lkdGg9Ijc4MCIgeG1sbnM9Imh0dHA6Ly93d3cudzMub3JnLzIwMDAvc3ZnIiB2ZXJzaW9uPSIxLjEiLz4= -[3]: https://news.itsfoss.com/linux-kernel-5-12-release/ -[4]: https://i2.wp.com/i.ytimg.com/vi/aOH43s9lm7I/hqdefault.jpg?w=780&ssl=1 -[5]: https://cdn.kernel.org/pub/linux/kernel/v5.x/ChangeLog-5.16 -[6]: http://lkml.iu.edu/hypermail/linux/kernel/2201.1/00613.html -[7]: https://www.kernel.org -[8]: https://git.kernel.org/torvalds/t/linux-5.16.tar.gz -[9]: https://itsfoss.com/upgrade-linux-kernel-ubuntu/ diff --git a/sources/news/20220112 GNOME Boxes 42 is Shaping Up as an Exciting Alternative to VirtualBox.md b/sources/news/20220112 GNOME Boxes 42 is Shaping Up as an Exciting Alternative to VirtualBox.md deleted file mode 100644 index 189fa19020..0000000000 --- a/sources/news/20220112 GNOME Boxes 42 is Shaping Up as an Exciting Alternative to VirtualBox.md +++ /dev/null @@ -1,98 +0,0 @@ -[#]: subject: "GNOME Boxes 42 is Shaping Up as an Exciting Alternative to VirtualBox" -[#]: via: "https://news.itsfoss.com/gnome-boxes-42-alpha/" -[#]: author: "Ankush Das https://news.itsfoss.com/author/ankush/" -[#]: collector: "lujun9972" -[#]: translator: " " -[#]: reviewer: " " -[#]: publisher: " " -[#]: url: " " - -GNOME Boxes 42 is Shaping Up as an Exciting Alternative to VirtualBox -====== - -GNOME Boxes is an easy-to-use virtualization software that lets you download operating systems from within the program or use ISO files to create new virtual machines. - -It is also the only program that lets you test upcoming GNOME versions, just like we tried [GNOME OS][1]. - -While it remains a simplified experience now, the upcoming version brings several UI updates to give you more control and customizations. - -In a [tweet][2], **Felipe Borges** (maintainer) shared some early development progress with Boxes 42 alpha build. - -I tried it out to give you some key highlights here. - -### GNOME Boxes 42 (Alpha): What’s New? - -![][3] - -Boxes, as a virtualization application, works well. However, the lack of options makes me want to [install VirtualBox to create virtual machines][4]. - -However, I think it might become a viable alternative to VirtualBox with the recent development updates. - -As per my experience with the alpha version, you get the usual welcome screen that highlights the essential aspects of the application.

However, to get a comfortable experience and use it as a desktop/server, Canonical officially recommends 4/8 GB RAM variants of the board. - -After all, memory requirements by modern distributions are gradually increasing. So, it only makes sense not to expect a desktop setup with a 2 GB RAM Raspberry Pi board. - -But, it looks like [Canonical has plans][2] to make that happen with a feature enabled in [Ubuntu 22.04 LTS][3], scheduled for release in April 2022. - -And, you can already test it out! Here’s what you need to know about it. - -### Performance Boost with Ubuntu 22.04 - -Canonical plans to use a Linux Kernel feature to achieve optimization that should let you have a viable Ubuntu Desktop experience with Raspberry Pi 4 2 GB RAM variant. - -Of course, it should give a performance boost to Ubuntu for Raspberry Pi in general. - -But, primarily, it aims to enable Raspberry Pi 4 2 GB RAM to give you a decent Ubuntu Desktop experience for the least investment. - -This improvement should be beneficial for education and other industries as well. - -The Linux Kernel feature that they plan to use is: **zswap**. - -zswap is a compression tool that intervenes with the processes being moved to hard drive or SD card. - -It compresses the process and checks if the process can be accommodated in the memory (RAM). If not, it will simply decompress the process and let it go to the swap space as usual. - -All of this happens faster than accessing a process from the swap area. In a nutshell, this new feature allows more processes to use the RAM than relying on the swap space, making the entire experience faster. - -### How Can You Test This Now? - -While this feature isn’t completely ready for Raspberry Pi 4 2 GB, you can enable it for the 4 GB and 8 GB RAM boards to get a noticeable performance boost. - -In any case, if you try it on your 2 GB Raspberry Pi board, you should consider sharing the experience in the [Ubuntu forums][4]. - -If you are feeling adventurous, you can try it by simply typing a single command in the terminal: - -``` - - sudo sed -i -e 's/$/ zswap.enabled=1/' /boot/firmware/cmdline.txt - -``` - -If you are not sure about what it will do, you should wait for Ubuntu 22.04 where it should be baked out of the box. - -You can also check out Dave Jones’s (Ubuntu Raspberry Pi Lead) [personal blog][5] to find out more technical details about these optimizations. - -Obviously, you should not expect a lot from a 2 GB RAM Raspberry Pi 4 board, but it is exciting to see improvements in Ubuntu 22.04 that will let more users get a Linux desktop experience with the least requirement. - -_What do you think about it?
