  • VirtIO-GPU Vulkan Driver Looks To Go Upstream In Mesa - Phoronix

    The VirtIO-GPU Vulkan driver is looking to be upstreamed in Mesa in allowing Vulkan support for virtualized guests that in turn is handled by the host's Vulkan driver/hardware.

    As part of the Virglrenderer project has been Vulkan rendering work and the VirtIO-GPU Vulkan driver component within Mesa for running on the guests.

    The VirtIO-GPU Vulkan driver code has been in the works by Google and developer Chia-I Wu has outlined their plan to get it upstreamed in Mesa.

  • AMD Instinct MI100 "Arcturus" Bits Added To Linux-Firmware.Git - Phoronix

    While AMD's open-source Linux graphics driver developers have been working publicly on the "Acturus" GPU support going back to 2019 that was then introduced last year in the form of the Instinct MI100, finally today has the necessary binary firmware been upstreamed into linux-firmware.git for enabling the rest of the open-source AMD Linux driver stack.

    For over one year the mainline Linux kernel has offered the AMD Arcturus GPU support and has continued improving with succeeding kernel releases. For its intended purpose the ROCm 4.0 compute stack introduced the MI100 support at launch. Mesa also has Arcturus support for video acceleration.

  • Bas Nieuwenhuizen: The Catastrophe of Reading from VRAM

    In this article I show how reading from VRAM can be a catastrophe for game performance and why.

    To illustrate I will go back to fall 2015. AMDGPU was just released, it didn’t even have re-clocking yet and I was just a young student trying to play Skyrim on my new AMD R9 285.

    Except it ran slowly. 10-15 FPS slowly. Now one might think that is no surprise as due to lack of re-clocking the GPU ran with a shader clock of 300 MHz. However the real surprise was that the game was not at all GPU bound.

    As usual with games of that era there was a single thread doing a lot of the work and that thread was very busy doing something inside the game binary. After a bunch of digging with profilers and gdb, it turned out that the majority of time was spent in a single function that accessed less than 1 MiB from a GPU buffer each frame.

    At the time DXVK was not a thing yet and I ran the game with wined3d on top of OpenGL. In OpenGL an application does not specify the location of GPU buffers directly, but specifies some properties about how it is going to be used and the driver decides. Poorly in this case.

    There was a clear tweak to the driver heuristics that choose the memory location and the frame rate of the game more than doubled and was now properly GPU bound.

  • Bas Nieuwenhuizen: A New Blog, Now What?

    This is the first post of this blog and with it being past midnight I couldn’t be bothered making one about a technical topic. So instead here is an explanation of my plans with the blog.

    I got inspired by the prolific blogging of Mike Blumenkrantz and some discussion on the VKx discord that some actually written updates can be very useful, and that I don’t need to make a paper out of each one.

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.
