  • Coreboot Starts Seeing Bits For AMD Barcelo

    Early work is underway on Coreboot for AMD's Barcelo as the successor to Lucienne.

    Merged on Saturday were the first bits of new code referencing AMD's Barcelo landing in Coreboot. The Barcelo code so far is building off the existing Cezanne Coreboot code while the bits added this weekend were for a new GPU PCI ID and vBIOS ID remapping. More code is needed moving forward but this shows they are already working towards Barcelo bring-up for Coreboot with these initial baby steps.

  • Linux 5.15 To Bring More Scalable + Reliable Open vSwitch - Phoronix

    Linux 5.15 later this year will bring improvements to the kernel side of Open vSwitch, the open-source virtual multi-layer switch implementation that is commonly used in large virtualized environments.

    Red Hat's work on per-CPU upcall dispatch handling for the Open vSwitch kernel code has made it into net-next this week, thereby effectively making it among the material now waiting around for the Linux 5.15 cycle.

  • Linux 5.0 shown to boot on ESP32 processor - CNX Software

    ESP32 IoT processor supports up to 8MB PSRAM which makes it just enough to run a minimal version of Linux. There’s little practical application for it, but it may be fun to try, and one developer apparently managed to boot Linux 5.0.0 on a board with an ESP32 dual-core Xtensa processor connected to 8MB PSRAM and a 2MB SPI flash.

  • Squeezing More Performance Out Of Intel Tiger Lake Xe Graphics By Using Mesa Git - Phoronix

    For OpenGL games the performance benefits to Mesa Git tended to be smaller than with the Vulkan tests. More benchmark results here. But in any event during the OpenGL and Vulkan testing I haven't run into any issues or regressions when using the current Mesa Git, thanks to Intel's very reliable QA/CI these days around their open-source graphics driver stack. Moving to this latest Mesa code for some Tiger Lake Xe Graphics benefits is easily achievable on Ubuntu systems by way of the Oibaf PPA. As it pertains to the Xe Graphics performance. at this stage there wasn't any clear benefit from moving past the Linux 5.11 kernel as shipped by Ubuntu 21.04.

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.
