  • Linux 5.17: Quicker Mount Times For XFS, Few New Features For EXT4 - Phoronix

    In addition to the Btrfs updates, the EXT4 and XFS file-system maintainers submitted their feature changes already for the in-development Linux 5.17 kernel.

    The main feature change for XFS with Linux 5.17 is the mount code only trying to free stale CoW staging extents if the file-system unmounted cleanly. In turn this means XFS mount times should be lower, especially for file-systems supporting reflinks and having a large number of allocation groups.

  • CXL Memory Hotplug Support Ready To Plug Into Linux 5.17 - Phoronix

    Over the past two years work has been ramping up a lot on Compute Express Link (CXL) enablement for the Linux kernel and with the in-development Linux 5.17 there is more feature code landing.

    The newest CXL subsystem support in place is CXL 2.0 memory hotplug handling, which is handled somewhat similarly to PCI. The ACPI SRAT Physical Address to Proximity Domain information is also extended for handling possible performance-class and memory-target nodes dynamically created from CXL memory.

  • Qualcomm Snapdragon 8 Gen 1 Sees Timely Support With The Mainline Linux 5.17 Kernel - Phoronix

    Qualcomm only announced the Snapdragon 8 Gen 1 and X65 platforms at the end of November but already they have managed to provide timely mainline support for these latest high-end SoCs. This is great to see compared to the days of slow to materialize mainline support for new Arm SoCs, which still persists among some vendors with either belated mainline support or only focusing on vendor downstream kernels. The big batch of Arm SoC/platform changes have landed for Linux 5.17.

    The big set of Arm platform/SoC changes is all ready for mainline Linux 5.17. New SoCs now supported by the mainline Linux 5.17 kernel include the Qualcomm Snapdragon 8 Gen 1, Snapdragon SDX65, NXP i.MX8ULP, Texas Instruments J721S2, and Renesas R-Car S4-8. Seeing prompt support for the Snapdragon 8 Gen 1 is exciting for that recently-announced SoC manufactured on a 4nm process and over the Snapdragon 888 advertises 20% better CPU performance and 30% more power efficient. Besides the SoCs itself, the reference boards for the new Qualcomm SoCs are also supported with Linux 5.17.

  • One-Line Patch To Intel's Vulkan Linux Driver Can Help Modern Games By A Few Percent - Phoronix

    A patch merged into Mesa 22.0 on Tuesday for Intel's "ANV" open-source Vulkan Linux driver is helping bump up the perforrmance in modern games.

    The one-line patch can help modern games both native and via Steam Play (Proton + DXVK) by a few percent. The change is simply increasing the binding table pool size from 4KB to 64KB.

  • Intel Arc Alchemist GPU gets 20-40% perf boost with Mesa 22.0 Linux OS | TweakTown

    Intel's new Arc Alchemist DG2 GPUs were meant to launch in Q1 2022 but now that's a mess and it's sometime in 2022, but Intel has been helping the Linux community by kick-starting their Xe HP pipeline optimization from the get-go so that Linux users wouldn't have to wait for compatibility.

    But then rolls in Mesa 22.0 which will have pixel pipeline optimizations, boosts to OpenGL and Vulkan performance in Intel discrete GPUs -- offering up to 40% more performance. In something like Unigine Valley, there was a huge 40% performance gain in Mesa 22.0 with Intel DG2-448 hardware. DOTA2 for example, had up to 30% more performance while Xonotic had up to 14% more performance... impressive numbers.

  • 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.
