  • Developers Call On Intel To Open-Source PSE Firmware As Their Newest Binary Headache - Phoronix

    With Intel's Atom x6000E "Elkhart Lake" SoCs there is a new block called the Programmable Services Engine (PSE) that is an Arm Cortex-M7 companion core that handles various tasks. Unfortunately, with the PSE it means a new binary-only firmware module. With the Programmable Services Engine likely to come with future Intel platforms too, Coreboot developers and open-source enthusiasts are calling on Intel to now open-source this firmware to avoid having this extra binary blob and further complicating future open-source firmware efforts.

    The Programmable Services Engine can be used for embedded controller (EC) functionality, sensor handling, network proxy, remote management, and other in-band and out-of-band device management tasks. Elkhart Lake is the first generation featuring the PSE.

  • Linux 5.17 Intel Graphics Driver Update Fixes Hangs, More Discrete vRAM Preparations - Phoronix

    Sent to DRM-Next this week for queuing until the Linux 5.17 merge window in January is the latest batch of drm-intel-gt-next updates, which has hang fixes and more preparations for Intel discrete graphics.

    There is already some Intel kernel graphics driver code that is queued for Linux 5.17, most notably including VRR support for Ice Lake. This week's drm-intel-gt-next has more notable changes for Intel's open-source driver that continues growing a lot for supporting their discrete graphics plans.

  • AMDVLK 2021.Q4.2 Released With Dynamic Rendering, Other New Extensions - Phoronix

    It's been over one month since the release of AMDVLK 2021.Q4.1 as the latest open-source AMD Vulkan driver update, which is off the wagon compared to the prior weekly/bi-weekly release cadence. But today thankfully it's been succeeded by AMDVLK 2021.Q4.2 as the newest driver release.

    Since early November when the last AMDVLK open-source driver release occurred, AMDVLK has been seeing new activity to primarily keep up with the new Vulkan API extensions being introduced upstream. Most notable with AMDVLK 2021.Q4.2 is supporting Vulkan's new dynamic rendering support. Mesa's RADV (and Intel's ANV) have already been working on their dynamic rendering support too and NVIDIA has offered VK_KHR_dynamic_rendering in their beta driver since last month.

Linux Community Updates 20 Year Old AMD GPU Driver

  • Linux Community Updates 20 Year Old AMD GPU Driver

    Back in 2002, if you were a hip PC gamer you were probably playing Grand Theft Auto Vice City on your brand new ATI Radeon R300 graphics card and listening to Avril Lavigne's "Sk8r Boi." Now that sk8r boi is probably a sk8r grandpa, the R300 is getting a new driver with a long-awaited bug fix.

    According to Phoronix, the ATI Radeon R300, R400, and R500 graphics cards are getting a new open-source graphics driver under Linux that will breathe extra life into these near 20-year-old GPUs. The new open-source driver is made by developer Emma Anholt, and is designed to give these GPUs the ability to request NIR shaders from the Mesa 3D graphics library's state tracker and use the NIR to TGSI path.

    NIR is an optimizing compiler stack that sits at the core of driver shader compilers from Mesa. Basically, it's an optimization layer that tries to reduce the amount of work a GPU has to do when running 3D applications.

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.
