  • Linux 4.20 Picks Up 6 x 4K Display Support For Vega 20, Initial RX 590 Support Fixes

    Usually this late into a current Linux kernel development cycle the DRM graphics driver fixes don't tend to be too notable, but that's certainly not the case with today's batch of AMDGPU and TTM fixes sent off to the DRM tree.

    Highlights of the AMDGPU Linux kernel driver fixes today come down to:

    - Support for being able to drive six 4K displays with the upcoming Vega 20 GPUs... Up until now Vega 20 would top out at 4 x 4K displays due to the minimum dcf clock value set, but now that's been corrected with a one line patch that will allow up to six 4K displays to function with the upcoming Radeon Instinct Vega 20 products.

  • VK_KHR_shader_float_controls and Mesa support

    Khronos Group has published two new extensions for Vulkan: VK_KHR_shader_float16_int8 and VK_KHR_shader_float_controls. In this post, I will talk about VK_KHR_shader_float_controls, which is the extension I have been implementing on Anvil driver, the open-source Intel Vulkan driver, as part of my job at Igalia. For information about VK_KHR_shader_float16_int8 and its implementation in Mesa, you can read Iago’s blogpost.

    The Vulkan Working Group has defined a new extension VK_KHR_shader_float_controls, which allows applications to query and override the implementation’s default floating point behavior for rounding modes, denormals, signed zero and infinity. From the Vulkan application developer perspective, VK_shader_float_controls defines a new structure called VkPhysicalDeviceFloatControlsPropertiesKHR where the drivers expose the supported capabilities such as the rounding modes for each floating point data type, how the denormals are expected to be handled by the hardware (either flush to zero or preserve their bits) and if the value is a signed zero, infinity and NaN, whether it will preserve their bits.

  • ARM Posts New "Komeda" Linux DRM/KMS Display Driver

    ARM developers have posted their first public patches for the new "Komeda" display driver for the Linux kernel that offers DRM/KMS integration.

    ARM's Komeda display driver is for supporting the D71 and later display processors. The Mali D71 is a big redesign to ARM's display IP that is more modularized and offers new functionality compared to their older display processors. Those unfamiliar with the D71 hardware and features but curious can learn more via community.arm.com.

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.
