  • The Linux Desktop Could "Soon" Get Support For Vulkan With 10-Bit Color Enabled

    Enabling 10-bit color is a non-issue on proprietary operating systems. That is far from being the case on the GNU/Linux desktop. Enabling 10-bit color on GNU/Linux is easy enough, but things like the Vulkan graphics API, the Steam games store and launcher, the KDE Plasma and Deepin desktop environments and Chromium hardware acceleration do not work. mpv developer Niklas Haas has submitted patches to the Mesa graphics stack that make it possible to run Vulkan games and applications on GNU/Linux desktops when 10-bit color is enabled.

  • AMD Sends In Aldebaran, FreeSync HDMI, Other Graphics Changes For Linux 5.13

    AMD on Friday submitted a big batch of AMDGPU driver changes to DRM-Next ahead of next month's Linux 5.13 merge window.

    This was a big set of feature changes in the works for Linux 5.13 and with this pull request some of the user noteworthy items include:

    - Initial support for Aldebaran, the next-gen CDNA GPU. At the end of February, AMD began posting the open-source Linux driver patches around Aldebaran as a new CDNA GPU following LLVM code appearing for GFX90A. Linux 5.13 will have initial support for Aldebaran.

  • Linux Looks To Finally Remove Its Legacy IDE Driver Support - Phoronix

    It's 2021 and proposed patches by upstream developers would finally remove Linux's legacy IDE driver code.

    The proposed code is for removing the legacy IDE driver support from the mainline kernel tree, likely beginning with the 5.13 kernel assuming all goes as planned. It was two years ago that the legacy IDE driver code was deprecated and marked for removal in 2021... We are now well into 2021, so Christoph Hellwig is following through and looking to have that removed.

  • Intel Tweaking Ice Lake Xeon Linux Power Management Code For Higher C6 Latency - Phoronix

    While Intel upstreamed their forthcoming "Ice Lake" Xeon processor support long ago and has been focused on next-gen Sapphire Rapids enablement now for the better part of the past year, there still are some Ice Lake Xeon tweaks taking place here and there. This week a new bleeding-edge patch is in testing for tweaking the power/performance behavior of Ice Lake Xeon with Intel's idle driver.

    For hitting the C6 low-power state with Intel's Ice Lake Xeon there are higher costs involved than existing Xeon processors. The C6 exit latency as the maximum time it takes the CPU from entering an idle state to executing the first instruction after a wake-up from that state has been increased. The Ice Lake Xeon C6 exit latency within the Intel Idle driver was at 128 micro-seconds but now has been bumped up to 170 microseconds. The exit latency change was attributed to using the median latency previously rather than worst-case latency, Meanwhile Xeon Scalable Skylake / Cascade Lake has a exit latency of 133 microseconds with this "intel_idle" driver.

  • AMDVLK 2021.Q1.6 Released With Radeon RX 6700 XT Support

    Following yesterday's release of the Radeon RX 6700 XT graphics card and the updated Radeon Software for Linux 20.50 driver, AMD has now released AMDVLK 2021.Q1.6 as their updated open-source Vulkan driver with Navi 22 / RX 6700 XT support.

    AMDVLK 2021.Q1.6 as the company's official open-source AMD Vulkan driver on Linux systems now carries RX 6700 XT / Navi 22 support. This is, of course, contingent upon AMDGPU support in the Linux kernel DRM driver which as outlined in my earlier review is in good shape for Linux 5.11+, assuming you have the Navy Flounder AMDGPU firmware files present on your system.

    Mesa has already been exposing RX 6700 XT support for both its RADV Vulkan driver and RadeonSI OpenGL driver. See the Radeon RX 6700 XT Linux review for the Mesa-based benchmarks and other driver support details.

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.
