  • Intel Gen12 Graphics Bring EU Fusion - EUs Fused In Pairs

    While we remain eager to find out more about (and benchmark) Intel Gen12 graphics in Tiger Lake and Xe discrete graphics with this generation bringing the biggest changes to the ISA since i965, Linux patches and bug reports do continue offering new tid-bits of information on Gen12.

    One bit that I don't believe has been reported publicly or at least not widely is that starting with Intel Gen12 graphics there is "EU Fusion" or the execution units now being paired for yielding a larger warp size.

  • "Navy Flounder" Is The Newest AMD Navi 2 GPU Being Added To The Linux Driver

    In addition to the "Sienna Cichlid" support recently published for the open-source AMD Radeon Linux kernel graphics driver, there is another new graphics processor being added to their driver: Navy Flounder.

    Sent out this week were patches for Navy Flounder as another Navi 2 part, Navi 22 to be exact. The patches mostly reuse the existing Sienna Cichlid code paths. The codename, like Sienna Cichlid, is the Linux naming convention currently being used by the AMD Linux team of a color followed by a fish species.

  • Sway 1.5 Wayland Compositor Released With Adaptive-Sync/VRR, New Protocols

    Sway 1.5 is out as a big feature update to this Wayland compositor inspired by the i3 window manager. A big user-facing feature with Sway 1.5 is support for Adaptive Synchronization / Variable Refresh Rate, such as AMD FreeSync.

    Up to now the FreeSync/Adaptive-Sync has been principally been in place for the Linux desktop when running on an X.Org session. However, Sway now supports Adaptive-Sync/VRR for reducing stuttering and tearing within games.

  • Early Intel DG1 Graphics Card Enablement Sent In To DRM-Next For Linux 5.9

    As we have been anticipating for weeks, initial (but still early) enablement of the Intel DG1 graphics card on their open-source driver stack will indeed be sent in for the upcoming Linux 5.9 cycle and is currently being queued in the DRM-Next repository.

    It was in late May that Intel sent out the DG1 patches to light up the graphics card on Linux and building off all the existing Gen12/Xe graphics code already mainlined within the kernel. Since then the kernel work has continued with other features getting squared away.

  • AMD Navi 22 is listed in a Linux patch under the fuzzy name “Navy Flounder”

    Some time ago there was a rumor that AMD had discovered that users were snooping around in their controllers to find clues about new products coming to market. There were rumors that AMD started using alternative code names to hide its graphics cards from prying eyes. Sienna Cichlid, who is believed to be Navi 21, was the first example that came to light. And now AMD seems to use the code name Navy Flounder to hide the silicon Navi 22.

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.
