Graphics: Wayland Release, Mesa, and Some Hacking

  • wayland 1.20.0
    Wayland 1.20.0 is released!
    
    This release contains the following major changes:
    
    - FreeBSD support has been entirely upstreamed and has been added to
      our continuous integration system.
    - The autotools build system has been dropped. Meson has replaced it.
    - A few protocol additions: wl_surface.offset allows clients to update
      a surface's buffer offset independently from the buffer,
      wl_output.name and description allow clients to identify outputs
      without depending on xdg-output-unstable-v1.
    - In protocol definitions, events have a new "type" attribute and can
      now be marked as destructors.
    - A number of bug fixes, including a race condition when destroying
      proxies in multi-threaded clients.
    
    Commit history since RC1 below.
    
    Simon Ser (2):
          meson: override dependencies to ease use as subproject
          build: bump to version 1.20.0 for the official release
    
    git tag: 1.20.0
    
  • Wayland 1.20 Released With Proper FreeBSD Support, Protocol Additions

    Wayland 1.20 is out today as the latest version of the reference Wayland library/support code and core protocol.

    While work on the core Wayland code itself has slowed down in recent years, Wayland 1.20 is a fairly notable update. In particular, this first Wayland release in nearly one year is bringing fully upstreamed FreeBSD support. All of the FreeBSD support patches have worked their way upstream into Wayland 1.20 and it's ready to be supported with this release. There is also now FreeBSD continuous integration (CI) test coverage to ensure the FreeBSD support remains in good shape and hopefully won't regress.

  • Cross-compiling with icecream - Samuel Iglesias Gonsálvez's blog

    One of the big issues I have when working on Turnip driver development is that when compiling either Mesa or VK-GL-CTS it takes a lot of time to complete, no matter how powerful the embedded board is. There are reasons for that: typically those board have limited amount of RAM (8 GB for the best case), a slow storage disk (typically UFS 2.1 on-board storage) and CPUs that are not so powerful compared with x86_64 desktop alternatives.

    [...]

    Icecream is a distributed compilation system that is very useful when you have to compile big projects and/or on low-spec machines, while having powerful machines in the local network that can do that job instead. However, it is not perfect: the linking stage is still done in the machine that submits the job, which depending on the available RAM, could be too much for it (however you can alleviate this a bit by using ZRAM for example).

    One of the features that icecream has over its alternatives is that there is no need to install the same toolchain in all the machines as it is able to share the toolchain among all of them. This is very useful as we will see below in this post.

  • Mesa's Virgl Code Lands Optimization For Lowering Memory Use - Phoronix

    It is not too often getting to talk about performance optimizations for Mesa's Virgl code that along with in conjunction with related "Virgil" components allows for hardware-accelerated 3D/OpenGL running within virtual machines. Hitting Mesa 22.0 this week though is some Virgl code improvements for allowing lower memory use within virtual machines.

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.
