  • Intel's Latest Compute Code Is Enabling OpenCL 3.0 For All Hardware Since Broadwell

    On Friday Intel released Compute-Runtime 20.40.18075 as their latest OpenCL / oneAPI Level Zero stack update with an updated IGC compiler and L0 loader. This release continues offering Level Zero 1.0 support for all hardware back to Skylake. On the OpenCL side, Intel continues providing OpenCL 3.0 support for the very latest Tiger Lake / Gen12 Xe Graphics while older generations are on OpenCL 2.1.

  • Intel Media SDK 20.3 Released With AV1 Decode, Rocket Lake + DG1/SG1 Support

    The Intel Media SDK provides their open-source C API for hardware-accelerated video encode/decode/filtering for their graphics hardware. As with the Intel Media Driver 20.3 release, the Media SDK 20.3 release is headlined by their API supporting AV1 video decoding support with the new driver. The API also has additions for Keem Bay platform support. The software developer kit also adds support for Rocket Lake platforms, adds the device IDs for Elkhart Lake, and adds support for DG1/SG1 discrete graphics cards.

  • AMD Sends Out Latest SFH Linux Driver Patches

    It was in January that AMD finally published an open-source Linux driver for their Sensor Fusion Hub used by AMD Ryzen laptops for various sensor functionality. As we approach the end of the year this driver still hasn't been mainlined yet but a new revision was sent out on Friday.

    Friday marked the eighth revision to the AMD "SFH" Linux kernel driver patches for supporting the sensor functionality on many Ryzen laptops. This was the first revision to the driver since the prior patches were sent out in August. This new version has cosmetic code changes, adds the initialization code within the probe function, and other code changes but seemingly nothing too major.

  • RADV ACO Lands NGG Geometry Shader Support

    Adding to the growing list of Mesa 20.3 features is now RADV ACO supporting NGG GS. Or rather, the Radeon Vulkan driver with the ACO back-end now supports geometry shaders with Next-Gen Geometry (NGG) as found on newer AMD GPUs.

    The NGG GS ACO support merged on Friday and is enabled by default. Along the way of wiring up this support new NIR capabilities were also introduced like the ability to count emitted primitives, filter out incomplete GS primitives, and other bits. There were also some ACO improvements too along the way aside from the actual NGG GS. There are also optimizations to reduce LDS bank conflicts and early GS space allocation.

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.
