  • Microsoft's Hyper-V DRM Display Driver Will Land For Linux 5.14 [Ed: Microsoft turning 'Linux' into proprietary software of Microsoft]

    Last summer Microsoft engineers posted a DRM kernel display driver for their Hyper-V synthetic video device. One year later after going through a few rounds of code review, this Hyper-V DRM driver will be going mainline with the upcoming Linux 5.14 kernel cycle.

  • Intel Finishes Linux 5.14 Graphics Driver Feature Work With More Alder Lake P Code

    Intel's open-source graphics driver engineers have sent in their final feature pull request to DRM-Next of new material they are wanting incorporated into Linux 5.14.

  • I'm Gonna Pretend I Didn't See That

    At present, mainline zink uses a hammer-and-nail methodology that I came up with last year: the total amount of GPU memory in use by resources in a given cmdbuf is tracked, and that amount is tracked per-context. If the in-use context memory exceeds a threshold of the total VRAM, the driver stalls, thereby freeing up all the resources that are in use so they can be recycled into new ones.

    There’s a number of problems with this approach, but the biggest one is that it fails to account for cases like a AAA game that just uses as much memory as it can in order to optimize performance/resolution/graphics. I discovered such a case some time ago while running Tomb Raider, and then I set out to improve things since it was costing me about 10% of my perf on the title screen.

    The annoying part of this problem is that the piglit test is a very uncommon case, and it’s tricky to handle it in a way that doesn’t also impact other cases which appear similar but need to not get memory-clamped. As a result, it’s tough to really do anything based on “overall” memory usage.

    In the end, what I decided on was using the per-cmdbuf memory usage counter to trigger a check for completed cmdbufs on submit, iterating over all the pending ones to check whether they’ve completed, resetting them and freeing associated resources when possible. This yields good memory reclaiming behavior for problem cases while leaving games like Tomb Raider untouched and definitely not deadlocking or anything like that.

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.
