  • Panfrost Gallium3D Lands Its New Bifrost Scheduler In Mesa 21.1 - Phoronix

    Hitting Mesa 21.1 this morning is a scheduler implementation for Panfrost Gallium3D, the open-source Arm Mali graphics driver.

    Lead Panfrost developer Alyssa Rosenzweig has been working to implement a scheduler in panfrost for the Arm Bifrost graphics code path. The scheduler has been in the works for a number of months and is passing the relevant conformance tests and has now been merged.

  • AMDVLK 2021.Q1.3 Brings Performance Tuning For War Thunder - Phoronix

    AMDVLK 2021.Q1.3 is out this morning as the latest snapshot of the official open-source AMD Radeon Vulkan driver for Linux systems that is derived from their shared platform driver sources.

    AMDVLK 2021.Q1.3 is on the lighter side with AMDVLK 2021.Q1.2 having arrived just over one week ago.

    Of the two listed driver changes, AMDVLK 2021.Q1.3 is rebuilt against the Vulkan API 1.2.168 headers.

  • Freedreno's MSM DRM Driver Adds More Adreno Support, Speedbin Capability For Linux 5.12 - Phoronix

    The MSM Direct Rendering Manager driver originally developed as part of the Freedreno effort for open-source Qualcomm Adreno graphics on Linux while now supported by the likes of Google and Qualcomm's Code Aurora engineers has some notable changes in store for the next Linux kernel cycle.

    New Adreno hardware support coming with Linux 5.12 is the A508, A509, and A512. The Adreno 508 is part of the Snapdragon 630 SoC, the mid-range Adreno 509 is found with the Snapdragon 636, and the Adreno 512 is what was found in the Snapdragon 660.

  • Intel "Protected Xe Path" Code Updated For Hardware-Protected GPU Sessions - Phoronix

    Intel PXP -- Protected Xe Path -- is a means of hardware-protected sessions for graphics clients on Gen12 / Xe Graphics. The support code for enabling PXP with their open-source Linux driver stack was updated this past week.

    While it's still under a "request for comments" flag and too late for possibly seeing it come with the soon-to-open Linux 5.12 merge window, this Intel PXP functionality is moving along and will be important for Xe server GPUs in public cloud type deployments where protected sessions are desirable for better segregation between shared resources.

  • 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.
