Here are Collabora’s Contributions to Linux Kernel 5.12

Filed under
News

Linux kernel 5.12 was just released last week, bringing numerous new features and improved hardware support. Among the biggest changes, there’s LTO support in Clang, a new dynamic thermal power management mechanism, initial support for zoned block devices for the Btrfs file system, kernel thread-based NAPI polling, eMMC inline encryption support, and support for the Lenovo IdeaPad platform profile.

Collabora’s contributions to Linux kernel 5.12 targeted the closing of the gap between hardware support on vendor trees and the mainline kernel tree. For that, they’ve contributed to the ChromeOS EC platform support, power/supply and reset/shutdown subsystems, Mediatek SoC support, and improved the V4L2 (Video4Linux) Async notifier API to be consistent and easier to use.

Kernel 5.12: Working to close the gap

  • Kernel 5.12: Working to close the gap

    While the kernel community has kept an always accelerating pace of development with no slowdown in sight, the release process has reached such maturity that a new release might sound a bit uneventful. But, when we are talking about one of the pieces of software used to fly that helicopter on Mars earlier this year, uneventful is exactly what you want.

    In fact, as the resilience of the release process is proven over and over, more and more companies have been able to drop their vendor trees based on decade old Linux versions, and base their work on the bleeding edge technologies available in the latest versions.

    At Collabora, we are more than ever dedicated to help vendors achieve this goal by closing the gap between hardware support on vendor trees and the mainline tree. In this release we have expanded that effort with our customary contributions all around the kernel, in particular we have paid attention to the Video4Linux APIs and hardware enablement.

  • 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.

Red Hat Hires a Blind Software Engineer to Improve Accessibility on Linux Desktop

Accessibility on a Linux desktop is not one of the strongest points to highlight. However, GNOME, one of the best desktop environments, has managed to do better comparatively (I think). In a blog post by Christian Fredrik Schaller (Director for Desktop/Graphics, Red Hat), he mentions that they are making serious efforts to improve accessibility. Starting with Red Hat hiring Lukas Tyrychtr, who is a blind software engineer to lead the effort in improving Red Hat Enterprise Linux, and Fedora Workstation in terms of accessibility. Read more
