  • mesa 20.2.0-rc4
    Hi list,

I'd like to announce mesa 20.2.0-rc4, which is now available for general
consumption. This is a pretty tame rc, and I think we're on track for the final
release next week. The biggest changes this week are a host of OpenBSD fixes,
and ACO and radv fixes. There's also one egl extension that's been backported
for Firefox.
  • Mesa 20.2 Aiming For Release Next Week As Big Advancement For Open-Source GPU Drivers

    The fourth and likely last release candidate of Mesa 20.2 is now available for testing while the formal release should happen next week.

    Mesa 20.2-RC4 has been described as a "pretty tame" release candidate by release manager Dylan Baker of Intel. At this stage he feels Mesa 20.2.0 should be out next week barring any major issues coming up in the days ahead.

  • weston 9.0.0
    Weston 9.0.0 is released! This release cycle has been pretty quiet,
with just a few new features:

- A new kiosk shell allows to display regular desktop apps in an
  always-fullscreen mode
- Improved testing infrastructure: the test harness has been
  redesigned, DRM tests are now supported, DRM and OpenGL tests are now
  enabled in our CI
- DRM panel orientation property support

As always, a number of bug fixes are included as well.

Thanks to all contributors!

Commit history since RC1 below (no changes apart from the version
bump).

      build: bump to version 9.0.0 for the official release

git tag: 9.0.0
  • Wayland's Weston 9.0 Released With Kiosk Shell For Always-Fullscreen Apps

    Weston 9.0 is out as the latest feature update to this Wayland reference compositor.

    Most notable to Weston 9.0 is the introduction of a kiosk/full-screen shell. This Weston kiosk shell runs applications always full-screen via XDG-Shell. This is intended for embedded use-cases and other scenarios where always running one application/surface at a time. This implementation can also help developers in creating their own kiosk-like shells in serving as example code.

  • NVIDIA Sends Out 1GB THP Support For Linux x86_64

    NVIDIA software engineer Zi Yan who specializes in the Linux kernel memory management subsystem today sent out a set of patches proposing the addition of 1GB THP support for the Linux kernel.

    The NVIDIA engineer is proposing 1GB transparent hugepages support for Linux on x86_64 hardware for being more flexible in reducing translation overhead and increasing the performance of applications that have a large memory footprint. Unlike Linux's huge page-tables (HugeTLB) code for supporting large memory footprints, the 1GB THP approach doesn't require application changes.

  • NVIDIA Engineer Sends Out Patches For Supporting Sync FDs + Sync Objects With Nouveau

    Longtime NVIDIA engineer Thierry Reding who has been involved with the open-source Nouveau driver efforts largely from an embedded/mobile Tegra angle last week sent out the newest patch series.

    The latest work by Reding is focused on supporting synchronization file descriptors (sync FDs) and synchronization objects (syncobj) with the Nouveau DRM kernel driver.

    A new kernel interface is proposed for submitting push buffers that can optionally return a sync FD or sync object to user-space. These synchronization FDs/objects are practical for synchronization operations between the GPU and other drivers like KMS display code.

  • Updated NVIDIA CUDA For WSL Brings Better Performance, PTX JIT [Ed: This bolsters a Microsoft attack on GNU/Linux (the EEE way). WSL was a failure; no reason to waste effort on it]

    Earlier this summer building off the latest Windows Subsystem for Linux 2 advancements by Microsoft, NVIDIA released early support for CUDA / GPU compute on WSL2. This week NVIDIA offered up a new version of their CUDA WSL support.

  • 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.
