  • Intel IGC Network Driver Queues XDP Support For Linux 5.13

    The Intel IGC network driver (not to be confused with their other IGC, the Intel Graphics Compiler) that supports their Gigabit/2.5G Ethernet devices has support for the Express Data Path (XDP) with the upcoming Linux 5.13 cycle.

    Linux XDP "eXpress Data Path" allows for hooking in eBPF programs at a lower-level to the driver for packet processing and any editing of the packet data. While Intel's drivers for their enterprise network hardware has already supported XDP, the IGC driver has not supported XDP until now for this high performance data path. See this Red Hat blog post for more background details on XDP.

  • Intel's Bus Lock Detection Might Be Ready For The Mainline Linux Kernel - Phoronix

    For longer than the past year Intel engineers have been working on wiring up the Linux kernel support to handle split lock detection and bus lock detection. Back in Linux 5.7 the split lock detection landed for warning or even killing the offending software should a split lock occur due to the significant performance impact and possible denial of service. Now it's looking like the bus lock detection code could be ready for mainline.

    After the split lock detection code was merged, Intel engineers turned their focus to bus lock detection for Linux. Again, important due to the performance penalties and possible denial of service implications. Bus locks can disrupt the performance to other CPU cores and are much slower than an atomic operation happening within a cache line. Like the split lock detection, the bus lock detection relies upon the CPU being able to notify the kernel when a user instruction acquires a bus lock.

  • Linux 5.13 To Enable The Keyboard/Touchpad Of Newer Microsoft Surface Laptops

    The quest of improving the Microsoft Surface laptop support under Linux continues. With Linux 5.13 there is going to be not only the Surface DTX driver but another new Surface driver queued up is "surface-hid" that will allow supporting the keyboard and touchpad on newer Surface devices.

    Currently with newer Microsoft Surface devices like the Surface Laptop 3 and Surface Book 3 the keyboard and touchpad are not supported when running the mainline kernel... There have been out-of-tree patches / DKMS modules but finally with Linux 5.13 there should be the support with the mainline kernel now that the surface-hid driver has made it into HID's "-next" branch ahead of the Linux 5.13 merge window opening in April.

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.
