  • Experimental Linux Patches Allow User-Space Peer-To-Peer DMA Between NVMe Drives - Phoronix

    A set of Linux kernel patches posted on friday allow peer-to-peer DMA (P2PDMA) transfers between NVMe drives using existing O_DIRECT operations or the NVMe pass-through interface from user-space.

    These patches allow for user-space transfers between NVMe solid-state drives in a more efficient manner via P2PDMA. The patches though at the moment are marked "request for comments" and there are some technical issues to overcome around scatter-gather lists (SGLs) and one of the DMA interfaces.

  • New TTM Allocator For AMDGPU Graphics Memory Landing With Linux 5.11 - Phoronix

    The recently proposed new TTM memory management page allocator that can yield 3~5x faster page allocation as tested with the AMDGPU kernel driver will be coming for Linux 5.11.

    Christian König has been working on this new TTM allocator code and where it changes to it by default -- not just for AMDGPU but also the older Radeon DRM driver and for other drivers too like Nouveau and VMWGFX that also make use of the TTM memory management code.

  • Intel "coIOMMU" Can Help With Performance For VMs When Using Direct I/O Access - Phoronix

    Currently when directly assigning I/O devices to virtual machines the guest memory needs to be statically pinned unless using a vIOMMU setup in which case it does not but there are performance implications there as well. Intel engineers though have been working on a virtual IOMMU implementation with DMA buffer tracking to overcome these limitations.

    With Intel's proposed "coIOMMU" implementation there is fine-grained pinning and vendor agnostic support for emulated or para-virtualized vIOMMUs. Yu Zhang of Intel presented at KVM Forum 2020 on this coIOMMU effort.

  • Intel Sends Out Linux Support For SGX Enclaves Support A 40th Time

    Intel didn't manage to get their Software Guard Extensions (SGX) support merged for the current Linux 5.10 LTS kernel cycle and it's still up in the air if it will be pulled in the near-term for providing the mainline kernel with SGX enclaves support.

    SGX enclaves support is about providing protected regions of code/data from unauthorized access or modification. SGX support has been around since Skylake and continues to be built upon including with upcoming Ice Lake Xeon servers. But getting mainline support for SGX has been quite an effort now taking years and as of this week up to forty rounds of code review.

    [...]

    The SGX v40 Linux patches also have a number of low-level fixes and other code improvements. More details on the SGX v40 Linux kernel patches via the mailing list. We'll see in December if SGX gets pulled into the Linux 5.11 merge window or if the Intel developers will keep working on pushing it to upstream into 2021.

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.
