  • Mesa 21.1 Wires Up Lima Shader Disk Cache

    When it comes to open-source Arm Mali graphics on Linux, the Panfrost Gallium3D driver is what's talked about the most given that it's for supporting newer generations of Mali graphics hardware. But the Lima Gallium3D driver effort remains ongoing for supporting older Mali 400/450 series hardware.

    For those with older Mali 400 Utgard GPUs in various Allwinner SoCs particularly, the Lima Gallium3D effort continues maturing. The newest feature that is complete is an on-disk shader cache.

  • AMD ROCm 4.1 Is Released With A Fine New Notice Saying "GUI-Based software" Is "Not Supported"

    The latest AMD Radeon Open Compute (ROCm) stack brings a few new features for AMDs data-center customers. OpenCL, which is what most GNU/Linux desktop applications use for GPU compute, is not even mentioned in the "What's New" section of the release notes. There is, instead, a shiny new notice on the ROCm documentation website saying "GUI-based software applications are currently not supported".

  • Mike Blumenkrantz: Layin That Pipe

    It’s no secret that CPU renderers are slower than GPU renderers. But at the same time, CPU renderers are crucial for things like CI and also not hanging your current session by testing on a live GPU when you’re deep into Critical Rewrites.

    So I’ve spent some time today doing some rewrites in the *pipe section of mesa, and let’s just say that the pipe was good with zink before, but it’s much, much better now.

  • PanVk: An Open Source Vulkan driver for Arm Mali Midgard and Bifrost GPUs

    The Panfrost project started as a reverse engineering effort to understand Arm Mali Midgard and Bifrost GPU internals. It quickly evolved to focus on the development of a Gallium driver based on this reverse engineering effort, which was progressively extended to support new GLES and GL features (we recently reached a point where we are almost GLES 3.0 and GL 3.1 comformant, and GLES 3.1 is in the pipe). Last year, a new compiler backend was added to support Mali Bifrost GPUs.

    With the Panfrost driver getting more and more mature, the natural next step was to work on an Open Source Vulkan driver for those GPUs.

  • PanVK Started For Open-Source Vulkan On Arm Mali GPUs - Phoronix

    Panfrost has been the Gallium3D driver providing open-source OpenGL for Arm Mali Bifrost and Midgard GPus while now "PanVK" is in development as an open-source Vulkan driver.

    Boris Brezillon formally announced the start of PanVK today. With Panfrost Gallium3D becoming quite mature, PanVK is the new focus in providing Vulkan API support for Arm Mali Midgard/Bifrost GPUs.

    PanVK is already in good enough shape to run the basic Vulkan cube demo but is not yet a conformant driver nor running most real-world applications. Performance optimizations also haven't yet been a focus until all core features are in place.

Collabora announce PanVk, an open source Vulkan driver for Arm

  • Collabora announce PanVk, an open source Vulkan driver for Arm Mali Midgard and Bifrost

    Open source consulting firm Collabora are certainly busy. While they work with Steam owner Valve on various things, they also work in other areas of Linux like driver development - their latest being PanVk.

    Extending the Panfrost driver which currently supports OpenGL and ES across Arm Mali Midgard and Bifrost GPUs, they're now looking at Vulkan support now that Panfrost is getting quite mature. PanVk itself is already being worked on, with enough of the Vulkan API implemented so that vkcube can run but it's still overall in the early stages of development so real-world applications need more functions added and optimization is not yet a focus.

PanVk – Panfrost gets a Vulkan driver

  • PanVk – Panfrost gets a Vulkan driver

    We’ve followed with interest the progress of the Panfrost open-source driver for Arm Mali Midgard and Bifrost GPUs which has gotten more traction over time with official support from Arm and is getting closer to OpenGL ES 3.0 compliance with work on OpenGL ES 3.1 on the way.

    But Collabora has now started working on PanVk driver for the more recent Vulkan graphics API, as part of the Panfrost project.


    That also means upstreaming to mesa will not happen right now, but only once Collabora engineers consider enough features are supported and the code base is clean enough.

  • 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.
