  • Linux Achieves 5.1M IOPS Per-Core With AMD Zen 3 + Intel Optane - Phoronix

    Linux kernel developers have been working tirelessly to squeeze more performance out of IO_uring and the block / I/O code in general. IO_uring lead developer Jens Axboe who also serves as the Linux block subsystem's maintainer (among other roles and major contributions over the years) has used his system as a baseline for evaluating such kernel improvements. He's now moved to using AMD Zen 3 while sticking to Intel Optane storage and is seeing a mighty speed boost out of AMD's latest processors.

    Rather than talking in the 3.5~3.8M IOPS per-core range for evaluating kernel improvements, he is now at over 5 million IOPS per core by upgrading to AMD Zen 3 hardware.

  • Open-source Allwinner V3 ISP driver to enable blob-free camera support in mainline Linux - CNX Software

    Bootlin has just submitted the first patchset for the Allwinner V3 image signal processor (ISP) driver in mainline Linux which should pave the way for a completely open-source, blob-free camera support in Linux using V4L2.

    There are several blocks in an SoC for camera support including a camera input interface such as MIPI CSI 2 and an ISP to process the raw data into a usable image. Add to this the need to implement the code for sensors, and there’s quite a lot of work to get it all working.

    Allwinner SDK comes with several binary blobs, aka closed-source binary, but Bootlin is working on making those obsolete, having first worked on Allwinner A31, V3s/V3/S3, and A83T MIPI CSI-2 support for the camera interface driver in the V4L2 framework (and Rockchip PX30, RK1808, RK3128 and RK3288 processors), as well as implemented support for Omnivision OV8865 and OV5648 image sensors earlier this year.

  • Initial Allwinner V3 ISP support in mainline Linux - Bootlin's blog

    Several months ago, Bootlin announced ongoing work on MIPI CSI-2 support for the Allwinner A31/V3 and A83T platforms in mainline Linux, as well as support for the Omnivision OV8865 and OV5648 image sensors. This effort has been a success and while the sensor patches were already integrated in mainline Linux since, the MIPI CSI-2 controller patches are on their way towards inclusion.

  • Linux 5.16 To Feature More Extensible VirtIO GPU Driver With "Context Types" Addition - Phoronix

    Google's work on the VirtIO DRM kernel driver around the notion of "context types" and being able to initialize different types of contexts is set to be merged for Linux 5.16 in opening up more use-cases for this driver that is an important part of the open-source virtualization graphics stack for graphics.

    The existing VirtIO GPU driver is modeled around Virgl protocol usage for 3D within guest virtual machines but with this context init / context type work is around being able to accommodate additional protocols for GPU communication between the guest VM and the host.

  • AMDVLK 2021.Q3.7 Driver Released With New Extensions, More Optimizations - Phoronix

    AMD has pushed out one more code drop of their AMDVLK official open-source Vulkan driver before ending out the quarter.

    AMDVLK 2021.Q3.7 is today's latest AMD Vulkan Linux driver release. It's quite an eventful update with two new extensions, some optimizations, and other updates.

  • 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.

Red Hat Hires a Blind Software Engineer to Improve Accessibility on Linux Desktop

Accessibility on a Linux desktop is not one of the strongest points to highlight. However, GNOME, one of the best desktop environments, has managed to do better comparatively (I think). In a blog post by Christian Fredrik Schaller (Director for Desktop/Graphics, Red Hat), he mentions that they are making serious efforts to improve accessibility. Starting with Red Hat hiring Lukas Tyrychtr, who is a blind software engineer to lead the effort in improving Red Hat Enterprise Linux, and Fedora Workstation in terms of accessibility. Read more
