  • Intel's IGC 1.0.4241 Graphics Compiler Adds DG1 Platform Support

    Significant with this new version of the IGC compiler is the DG1 platform is supported, their first graphics card. IGC already supported Gen12/Xe while now the initial bits are in place for the forthcoming DG1 discrete graphics card. For weeks now we've been seeing Intel's many open-source developers posting new DG1 enablement patches from the Linux kernel through their Mesa stack to the media encode/decode driver and now working its way into DG1 for their compute stack. Obviously you also need to be running on the future Linux 5.9 kernel and more for getting this DG1 support all aligned but at least the IGC side work is now in place.

  • Weston 9.0 release schedule
    Hi all,
    
    Here is the release schedule for Weston 9.0, the next major version:
    
    - Alpha: July 30th, in 4 weeks
    - Beta: August 13th
    - RC1: August 27th
    - First possible release: September 3rd
    
    Package maintainers are encouraged to pick up the pre-releases to make
    sure packaging can be tested (and fixed) before the stable release.
    
    Let me know if there's something in particular you want merged for 9.0.

  • Wayland's Weston 9.0 Aims For Release In Early September

    With Weston 8.0 having shipped in January, Wayland developers are beginning to prepare for the next feature release of this reference Wayland compositor.

    Simon Ser has once again stepped up to take over Weston release management duties. He is planning to tag the Weston 9.0 Alpha at the end of June, a Weston 9.0 Beta in mid-August, and a first release candidate at the end of April. If all goes well he hopes to ship Weston 9.0 on 3 September but could be delayed by some days if additional release candidates are warranted.

  • LLVMpipe Gallium3D Driver Now Exposes OpenGL 4.0

    The LLVMpipe Gallium3D driver that provides a software/CPU-based OpenGL implementation for running on systems as a fallback path when no GPU / hardware OpenGL driver is available, a vendor-neutral path for debug purposes, and similar use-cases, now has OpenGL 4.0 support.

  • NVIDIA Video Codec SDK 10 Brings Few Changes For This Proprietary Library

    NVIDIA has quietly released Video Codec SDK 10 as the newest version of their proprietary video encode/decode implementation designed for their GPUs.

    [...]

    NVIDIA has already contributed to FFMpeg support for using the new NVENC presets, multi-pass encode modes, and low-delay key frame scaling for this video library as part of the Video Codec SDK 10 support. A follow-up commit added additional H.264 levels now supported.

  • RadeonSI Switches To Make Greater Wave64 Use On Navi

    While RDNA/Navi brought Wave32 support, the open-source RadeonSI Gallium3D driver for Linux has decided to switch to make greater use now of Wave64 for more shaders.

    [...]

    The change to use Wave64 for more shader stages was merged this week for Mesa 20.2. The commit does add the new "nggctess" perf flag for always using NGG culling for tessellation, complementing the existing nggc (for always using NGG culling) and nonggc for disabling NGG culling.

  • Mike Blumenkrantz: Binding Locations

    So let’s get down to pixels. The UBO indexing is now fixed-ish, which means moving onto the next step: setting up bindings for the UBOs.

    A binding in this context is the numeric id assigned to a UBO for the purposes of accessing it from a shader, which also corresponds to the uniform block index. In mesa, this is the struct nir_variable::data.binding member of a UBO. A load_ubo instruction will take this value as its first parameter, which means there’s a need to ensure that everything matches up just right.

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.
