  • USB Changes For Linux 5.17: Overdue Xen pvUSB To DWC3 Multi-Stream Transfer - Phoronix

    Landing this week as part of the various subsystems overseen by Linux's second-in-command Greg Kroah-Hartman were the USB changes for Linux 5.17.

    There were many USB (and Thunderbolt) changes for Linux 5.17 such as Synopsys' DWC3 "Multi-Stream Transfer" feature, Xen pvUSB making its debut after being out-of-tree since its start in ~2008, various power management changes, and more. Some of the USB subsystem highlights for 5.17 include:

    - Multi-Stream Transfer (MST; not to be confused with DisplayPort's MST - Multi-Stream Transport) for the Synopsys DesignWare Core SuperSpeed USB 3.0 controller. Synopsys added Multi-Stream Transfer to improve bulk streams performance for SuperSpeed and SuperSpeed Plus with their DWC3 controller with this latest Linux kernel driver code. Synopsys has found this Multi-Stream Transfer mode for DWC3 can lead to a "significant performance improvement" for UASP transfers.

  • Linux 5.16 speeds up games and boosts system performance - Market Research Telecast [Ed: Automated translation]

    Linux 5.16 took a week longer than originally expected. Linus Torvalds decided to give the kernel a little more time to mature. The triggers were not problems or alarming test results, but simply the concern that testing could be too short due to the holidays and the week “between the years”.

  • Mesa's "Copper" Is A Step Closer To Being Brazed - Phoronix

    A draft merge request has been opened for landing "Copper" within Mesa.

    Copper came about over the past year by Red Hat's Adam Jackson with participation from Mike Blumenkrantz and others. This DRI interface extension can lead to much greater efficiency for Zink, the OpenGL on Vulkan implementation, and native WSI handling for it. Copper would help improve upon the Gallium3D architecture and provide substantial benefits for Zink.

    On Thursday Blumenkrantz opened the draft MR for merging Copper with hopes for getting the code into shape for mainlining but not necessarily in the immediate future. Pushing Copper out as more of a longer-term effort is it depending upon other open merge requests such as Zink external memory support, sparse textures, and other bits.

  • Leaks

    It’s come to my attention that there’s a lot of rumors flying around about what exactly I’m doing aside from posting the latest info about where Jason Ekstrand, who coined the phrase, “If it compiles, we should ship it.” is going to end up.

    Everyone knows that jekstrand’s next career move is big news—the kind of industry-shaking maneuvering that has every BigCo from Alphabet to Meta on tenterhooks. This post is going to debunk a number of the most common nonsense I’ve been hearing as well as give some updates about what else I’ve been doing besides scouring the internet for even the tiniest clue about what’s coming for this man’s career in 2022.

    [...]

    Unfortunately, this turned out to be bogus, no more than chaff deployed to stop us from getting to the truth because we were too close. Later, while I was pondering how buggy NVIDIA’s sparse image functionality was in the latest beta drivers and attempting to pass what few equally buggy CTS cases there were for ARB_sparse_texture2, I stumbled upon the obvious.

    It’s so obvious, in fact, that everyone overlooked it because of how obvious it is.

    Jason has left Intel and turned in his badge because he’s on vacation.

    As everyone knows, he’s the kind of person who literally does not comprehend time in the same way that the rest of us do. It was his assessment of the HR policy that in order to take time off and leave the office, he had to quit. My latest intel (no pun intended) revealed that managers and executives alike were still scrambling, trying to figure out how to explain the company’s vacation policy using SSA-based compiler terminology, but optimizer passes left their attempts to engage him as no-ops.

Samsung, Red Hat to Work on Linux Drivers for Future Tech

The 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. Read more

  • How to install go1.19beta on Ubuntu 22.04 – NextGenTips

    In this tutorial, we are going to explore how to install go on Ubuntu 22.04 Golang is an open-source programming language that is easy to learn and use. It is built-in concurrency and has a robust standard library. It is reliable, builds fast, and efficient software that scales fast. Its concurrency mechanisms make it easy to write programs that get the most out of multicore and networked machines, while its novel-type systems enable flexible and modular program constructions. Go compiles quickly to machine code and has the convenience of garbage collection and the power of run-time reflection. In this guide, we are going to learn how to install golang 1.19beta on Ubuntu 22.04. Go 1.19beta1 is not yet released. There is so much work in progress with all the documentation.

  • How To Install MongoDB on AlmaLinux 9 - idroot

    In this tutorial, we will show you how to install MongoDB on AlmaLinux 9. For those of you who didn’t know, MongoDB is a high-performance, highly scalable document-oriented NoSQL database. Unlike in SQL databases where data is stored in rows and columns inside tables, in MongoDB, data is structured in JSON-like format inside records which are referred to as documents. The open-source attribute of MongoDB as a database software makes it an ideal candidate for almost any database-related project. This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo‘ to the commands to get root privileges. I will show you the step-by-step installation of the MongoDB NoSQL database on AlmaLinux 9. You can follow the same instructions for CentOS and Rocky Linux.

  • Self-host a Ghost Blog With Traefik

    Ghost is a very popular open-source content management system. Started as an alternative to WordPress and it went on to become an alternative to Substack by focusing on membership and newsletter. The creators of Ghost offer managed Pro hosting but it may not fit everyone's budget. Alternatively, you can self-host it on your own cloud servers. On Linux handbook, we already have a guide on deploying Ghost with Docker in a reverse proxy setup. Instead of Ngnix reverse proxy, you can also use another software called Traefik with Docker. It is a popular open-source cloud-native application proxy, API Gateway, Edge-router, and more. I use Traefik to secure my websites using an SSL certificate obtained from Let's Encrypt. Once deployed, Traefik can automatically manage your certificates and their renewals. In this tutorial, I'll share the necessary steps for deploying a Ghost blog with Docker and Traefik.
