Graphics: RadeonSI Gets NIR Improvements, Enabled By Default For Civilization VI, Mesa 19 is Almost Ready, Now at Fifth RC

  • RadeonSI Gets NIR Improvements, Enabled By Default For Civilization VI

    The RadeonSI NIR back-end as an alternative to its longstanding TGSI usage continues to be improved upon as a prerequisite for supporting OpenGL 4.6 with SPIR-V ingestion. A fresh batch of RadeonSI NIR work was merged today, including to enable it by default for one Linux game.

    Several developers landed the latest NIR code into Mesa 19.1 Git on Monday, including Marek Olšák who added a radeonsi_enable_nir option to DriConf for allowing the NIR usage to be flipped on a per-game/per-executable basis. Up to now users had to manually set R600_DEBUG=nir (or now, AMD_DEBUG=nir as the other syntax now supported in recent days with Mesa 19.1). But now with this DriConf option, it can "whitelist" games as needed.

  • mesa 19.0.0-rc5

    Hi List,

    Hot off the press is mesa 19.0-rc5. Due to a number of still opened bugs in the
    release tracker this will not be the final release, and I predict at least one
    more release candidate before the final release happens.

    Just an FYI, I will not be working Thursday or Friday this week, so if I don't
    respond to nominations after tommorrow don't be surprised Smile

    Anyway, in the rc5 release we have a little bit of everything, but not too much
    of any one thing:

    - nir
    - radv
    - v3d
    - intel
    - swr
    - anv
    - spirv
    - meson
    - radeonsi

  • Mesa 19.0-RC5 Released As The Cycle Drags Into Overtime

    Mesa 19.0-RC5 was issued a short time ago as the latest release candidate for Mesa 19.0. Due to blocker bugs remaining, at least one more release candidate is likely next week before seeing the official release.

    The 19.0 bug tracker still shows more than a half dozen bugs blocking the release. These blocker bugs range from 1~2% performance regressions in Unigine benchmarks with Skylake graphics to other random performance regressions and also some test case failures on the Intel side.

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.
