  • A Big Batch Of AMD Graphics Driver Updates Just Sent Out For Linux 5.16 - Phoronix

    Building off the earlier DRM-Next staged code from last month that brought initial DisplayPort 2.0 support and other feature work, another feature pull request was submitted today of additional AMD Radeon "AMDGPU" kernel driver changes slated for Linux 5.16.

    Alex Deucher has sent out another big batch of AMDGPU/AMDKFD driver updates destined for Linux 5.16. Feature work is beginning to wind down as the DRM-Next cutoff approaches ahead of next month's Linux 5.15 merge window while we'll see if any additional feature code tries to make it in ahead of time.

  • Radeon Gallium3D Picks Up A Nice Performance Optimization For iGPU/dGPU PRIME Setups - Phoronix

    The AMD Radeon Gallium3D driver code today landed a nice optimization for benefiting PRIME setups with integrated and discrete Radeon GPUs.

    With this latest code for Mesa 21.3-devel to the RadeonSI driver, copies from the discrete GPU to the integrated GPU for presentation on the screen are now done asynchronously. These async copies are done using the SDMA engine and in turn allows the discrete GPU to handle more work. An Async compute context is also used as a fallback to async SDMA copies. The patch summed it up quite simply, "Doing this copy using SDMA frees up the dGPU to do more interesting things while the copy is happening; for instance the rendering of the next frame."

  • X.Org Modesetting Driver Will Now Better Handle Multi-Montior Mixed-VRR Setups - Phoronix

    The xf86-video-modesetting DDX driver that is commonly in use for systems running an X.Org Server will soon find better support if you have a multi-monitor configuration where only some displays can support variable rate refresh (VRR / Adaptive-Sync / FreeSync).

    When the X.Org modesetting driver currently encounters a multi-monitor system where some displays are VRR capable and others not, the VRR-capable property was being set simply on whatever the last added DRM output could support. So depending upon whether the VRR-capable monitor was plugged in last or not would impact whether you could make use of it with this generic driver.

  • Mesa 21.3 Enables NGG Culling By Default For RDNA2 GPUs - Phoronix

    The Radeon Vulkan driver "RADV" within Mesa 21.3 is enabling NGG culling by default for Radeon RX 6000 series (RDNA2) GPUs and newer as another performance win.

    NGG culling was added to RADV this summer but initially only exposed as an opt-in feature via environment variable. This NGG-powered removal of unneeded triangles during rendering is also supported on RDNA1 / Navi 1x GPUs but is not being enabled by default -- our own tests with Navi 1x have confirmed the results to be a wash while the support is in good standing for the latest-gen GPUs.

  • AMD publishes GPUFORT as Open Source to address CUDA’s dominance

    NVIDIA dominates the parallel computing industry largely thanks to its own solution, CUDA. In response to this domain, AMD has published the source code of GPUFORT , a project that will be under Radeon Open eCosystem (ROCm) and that aims to offer a translation tool so that large code bases in CUDA can work outside of the closed ecosystem. of the green giant.

    The domain of CUDA and the fact that it is proprietary and owned by NVIDIA greatly limits the ability of developers to migrate to an alternative, so AMD has been working for a long time on mechanisms that help migrate specific CUDA code to interfaces compatible with its parallel computing stack supported by Radeon technology.

    Most of AMD’s efforts so far have focused on code written in C and C ++. GPUFORT, for its part, is to provide support for the translation from source to source ( source to source ) of CUDA Fortran and Fortran code based on OpenACC to OpenMP 4.5+ for execution on GPU or Fortran + HIP C ++ code .

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.
