  • Custom Linux allows Raspberry Pi to drive ADI peripherals

    Called Kuiper Linux, it incorporates Linux device drivers for ADI products, and supports other hardware including Digilent Zedboard, TerASIC DE10-Nano and Digilent Cora

    “The reasoning behind creating this distribution is to minimise the barriers to integrating ADI hardware devices into a Linux-based system,” according to the company. “When starting with a generic Linux distribution, the kernel typically would have to be rebuilt with the desired drivers enabled. While this is not difficult for an engineer that is familiar with the process, it can be a daunting task even when everything goes right. ADI Kuiper Linux solves this problem, and includes a host of additional applications, software libraries, and utilities.”

  • Rust takes a major step forward as Linux's second official language | ZDNet

    It wasn't that long ago that the very idea that another language besides C would be used in the Linux kernel would have been laughed at. Things have changed. Today, not only is Rust, the high-level system language moving closer to Linux, it's closer than ever with the next "patch series to add support for Rust as a second language to the Linux kernel."

  • Apple SoC PMGR driver for 5.17
    Hi SoC folks,

Please merge the new PMGR driver for 5.17.

This should not have any hard deps with the previous pulls. The 
MAINTAINERS change already rode along the DT pull, for simplicity.
  • More Apple Silicon M1 Bring-Up On The Way For Linux 5.17 - Phoronix

    The enablement work for supporting Apple's M1 SoC under Linux continues and with the v5.17 kernel next year will be yet more additions.

    Among the new driver activity for Linux 5.17 is an Apple PMGR driver for controlling the power states. The Apple PMGR block on their SoC has high-level power state controls for SoC devices. At the moment not all features are supported but important step forward for power management with Apple Silicon on Linux.

  • Intel's SWR Removed From Mainline Mesa, More Classic Code Cleaning Continues - Phoronix

    Last Friday Mesa classic drivers were removed from the mainline code-base and punted off to an "Amber" code branch where they will receive whatever attention moving forward. With that classic Mesa code removed, more code cleaning is now happening on top of the tens of thousands of lines of code already removed. Intel's OpenSWR driver has also now been removed from mainline.

    Since the original classic Mesa drivers consisting of Radeon R100/R200, original Nouveau, and Intel i915 / i965 drivers were removed, more code cleaning can now happen on mainline for code that was just sticking around for these old, rather unmaintained drivers.

  • XWayland Lands DRM Leasing Support To Handle VR Headsets - Phoronix

    Along with XWayland touchpad gestures, another shiny feature was merged this week into X.Org Server Git for XWayland: DRM leasing support!

    XWayland now has mainline support for the DRM leasing (drm-lease-v1) protocol for allowing X11 clients running through XWayland to lease non-desktop connectors/outputs from the underlying Wayland compositor. This is particularly useful and designed around the needs of virtual reality (VR) head-mounted displays.

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.
