  • Radeon's AMDVLK Driver Does Support FreeSync/VRR But The Option Isn't Widely Known

    There is a common misconception that the official AMD Radeon open-source Vulkan driver "AMDVLK" doesn't support FreeSync / Variable Rate Refresh, but that is actually inaccurate as the support was merged earlier this year albeit never announced or made it into the release notes.

    Going on for years have been bug reports and feature requests pertaining to FreeSync / VRR / Adaptive-Sync being missing / not supported by AMDVLK as the official open-source Radeon Vulkan driver for Linux.

  • Xfb And Barriers

    In the course of working on some code to introduce more granular resource-based pipeline barriers for synchronization, I rediscovered some parts of the xfb implementation we have that use barriers, and this got me thinking about our barrier usage in general for buffer resources.

  • Melissa Wen: If a warning remains, the job is not finished.

    In the past few weeks, I have been combing two issues on vkms: development of writeback support and alpha blending. I try to keep activities in parallel so that one can recover me from any tiredness from the other Tongue

    Alpha blending is a TODO[1] of the VKMS that possibly could solve the warning[2] triggered in the cursor-alpha-transparent testcase. And, you know, if you still have a warning, you still have work.

  • Linux vs. Windows Performance Will Be All The More Interesting With Intel's Hybrid x86 Architecture

    With Intel's Lakefield and the future Alder Lake with their hybrid x86 architecture mixing of "little" and "big" cores, operating system optimizations become all the more important and thus will be interesting to see how the battle is between Windows and Linux.

    At last week's Intel Architecture Day there was one slide in particular calling out to the "OS optimizations" with hybrid architectures. In that context it was for Lakefield and the mentioned OS optimizations were on Windows.

  • The New OpenBenchmarking.org Now In Alpha For Better Hardware & Benchmark Discovery

    As alluded to previously, a major overhaul of OpenBenchmarking.org has been in the works for a number of months now including a completely brand new analytics engine as part of the Phoronix Test Suite 10.0 development with its release due out later this year. With the new OpenBenchmarking.org now in good enough shape at least for the internal infrastructure, this new version is being opened up to the public today while over the weeks ahead more features will continue to be flipped on.

  • Phoronix Test Suite 10.0 Milestone 1 Released For Open-Source Benchmarking

    The first development release of the forthcoming Phoronix Test Suite 10.0-Finnsnes is now available for evaluation for this open-source, cross-platform, fully-automated benchmarking software framework.

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.
