  • AMD SEV-SNP Support Revised For Linux + Updated Hyper-V Isolation VM Code - Phoronix

    AMD engineers and their partners continue work towards upstreaming Secure Encrypted Virtualization's Secure Nested Paging (SEV-SNP) support for the mainline Linux kernel. 

    AMD SEV-SNP debuted this year with EPYC 7003 "Milan" processors. SEV-SNP offers additional hardware features for EPYC's virtualization capabilities. With SEV-SNP there is additional memory integrity protections around replay protection, data corruption, memory aliasing, and memory re-mapping. There are also other hardware protections with SEV-SNP as outlined in the comparison below. 

  • Kernel 5.13: Growing team and KernelCI hackfest

    As many developers in the northern hemisphere start to dream about their quickly arriving summer vacations, the increasing pace of kernel development gives no sign of taking a break any time soon. In fact, 5.13 was a record breaking release in the number of developers: exactly 2,062 developers contributed to this release - 336 of them for the first time. This was also the first kernel release with over 2,000 unique contributors. Collabora is, of course, the proud employer of a small, but very active, fraction of these developers.

    As usual, our team is working all around the kernel, fixing bugs and writing new features. In this release, Boris Brezillon fixed some hard-to-track bugs in the Panfrost DRM driver, improving the overall support for the platform. Ezequiel Garcia continued to improve the VP8 stateless codec and this time he moved part of the driver out of staging. Sebastian Reichel, who is on a quest to organize the device-tree description of drivers on the Power-Supply subsystem that he maintains, converted most of the DT descriptors to use the DT schema, such that they can be checked for compliance automatically. Dafna Hirschfeld and Enric Balletbo i Serra worked on MediaTek devices, fixing DRM/multimedia bugs and improving power management support, respectively.


  • Real-Time Patches Updated For The Linux 5.13 Kernel - Phoronix

    Thomas Gleixner has announced the release of the real-time "RT" patches for the Linux 5.13, the first update since the patches were re-based early on back during the 5.12 release candidates. 

    This morning's 5.13-rt1 release re-bases these real-time patches against the Linux 5.13 code-base, contains a rework of the locking core code, also reworks "large parts" of the memory management code, and other updates. 

  • QNAP network storage: NAS operating system QTS 5.0 with new Linux kernel

    QNAP provides the QTS 5.0 operating system as a beta version for some of its NAS systems. The update comes with some fundamental changes, including an updated Linux kernel to version 5.10. Until now, the manufacturer used kernel versions 4.2.8 or 4.14.24, depending on the processor.

    In practical use, the new Linux kernel is intended to increase the speed of PCI Express SSDs with NVMe protocol in particular when they function as a cache, for example when buffering data on hard drives. QNAP speaks in the announcement also of “improvements with AMD processors” without going into detail.

  • A Control Panel / UI For Intel's Linux Graphics Drivers Is Still Under Evaluation - Phoronix

    At the end of last year we reported on the possibility of an Intel Command Center / graphics driver control panel for Linux but not set in stone. The latest to report on the matter of an Intel Linux graphics GUI solution is that it's still being evaluated by the company. 

    When recently inquiring about the state of IGC compiler usage by their Mesa drivers, I also asked whether there was anything new to report on the prospects of an Intel Linux graphics driver control panel akin to the Intel Command Center on Windows.

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.
