  • Intel Lands A Hefty Tiger Lake Graphics Optimization - Phoronix

    From my Tiger Lake testing so far with the Core i7 1165G7, the "Gen12" Xe Graphics have been quite compelling with a very nice upgrade over Gen11 and especially obvious win over the very common still Gen9 graphics. With Mesa 20.3, another measurable performance is on the way for the Intel Vulkan driver with Tiger Lake.

    For Tiger Lake (and theoretically Rocket Lake as well), a new and significant optimization landed today in Mesa 20.3-devel. The optimization applies for Intel Gen12 graphics except for discrete/DG1 graphics.

  • Vulkan Specification Version 1.2.158 Brings Two New Extensions

    Version 1.2.158 of the Vulkan specification introduces VK_KHR_fragment_shading_rate that lets developers change the rate at which fragments are shaded on a per-region, per-primitive or per-draw basis and VK_KHR_shader_terminate_invocation which, together with the previously introduced VK_EXT_shader_demote_to_helper_invocation extension, lets developers do a much more specific OpKill.

  • Open-Source RADV Vulkan Driver Is Seeing Work To Allow Building It On Windows - Phoronix

    An independent party has slowly begun merging patches into mainline Mesa for allowing the open-source Radeon Vulkan driver "RADV" to build on Microsoft Windows.

    AMD is not behind this effort nor Valve but has been worked on in recent months for making Mesa's Radeon Vulkan driver code compatible with Windows. James Park of a little known "Lag Free Games" has been behind this initiative to bringing it to Windows and seemingly only explaining in private to upstream Mesa developers his motivations for doing so.

    RADV as a reminder is the Mesa Radeon Vulkan driver started out by David Airlie of Red Hat and Bas Nieuwenhuizen of Google in the time while waiting for AMD to open-source their Vulkan driver. AMD ultimately provided "AMDVLK" as their official open-source Vulkan driver derived from their internal Vulkan driver sources and built against the AMDGPU LLVM compiler back-end.

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.
