Graphics: RADV Vulkan vs. RadeonSI OpenGL, Open-Source OpenCL, VIA Graphics & Other Vintage GPUs

  • RADV Vulkan vs. RadeonSI OpenGL Performance With Linux 4.13 + Mesa 17.3-dev

    It's been a few weeks since last delivering any large RADV/RadeonSI open-source AMD Linux graphics benchmark results due to being busy with testing other hardware as well as battling some regressions / stability problems within the AMDGPU DRM code and Mesa Git. But with Linux 4.13 stable and the newest Mesa 17.3-dev code, things are playing well so here are some fresh OpenGL vs. Vulkan benchmarks on three Radeon graphics cards.

  • Open-Source OpenCL Adoption Is Sadly An Issue In 2017

    While most of the talks that take place at the annual X.Org Developers' Conference are around the exciting progress being made across the Linux graphics landscape, at XDC2017 taking place this week at Google, the open-source GPGPU / compute talk is rather the let down due to the less than desirable state of the open-source OpenCL ecosystem.

    Tom Stellard who formerly worked for AMD on their LLVM compiler stack and compute initiatives who recently joined Red Hat provided a "Current state of Open Source GPGPU" talk. It's not too much of a surprise if you are up-to-date in your daily Phoronix reading and our close coverage of all things Linux GPU. But if you're not a devoted reader or looking for an hour synopsis, check out his presentation embedded in this article.

  • VIA Graphics & Other Vintage GPUs Still Interest At Least One Developer In 2017

    Kevin Brace, the sole active developer left working on the OpenChrome driver stack for VIA x86 graphics, presented yesterday at XDC2017 about his work on this driver and how in the years to come he still hopes to work on other vintage GPU support.

    Brace's work mostly covered his personal motivations, a brief history of Via Unichrome and the Linux driver options, and then his recent work on trying to get the OpenChrome DDX and DRM drivers into shape.

FreeBSD-Based TrueOS 17.12 Released

The FreeBSD-based operating system TrueOS that's formerly known as PC-BSD has put out their last stable update of 2017. TrueOS 17.12 is now available as the latest six-month stable update for this desktop-focused FreeBSD distribution that also offers a server flavor. TrueOS continues using OpenRC as its init system and this cycle they have continued improving their Qt5-based Lumina desktop environment, the Bhyve hypervisor is now supported in the TrueOS server install, improved removable device support, and more.

An introduction to Joplin, an open source Evernote alternative

Joplin is an open source cross-platform note-taking and to-do application. It can handle a large number of notes, organized into notebooks, and can synchronize them across multiple devices. The notes can be edited in Markdown, either from within the app or with your own text editor, and each application has an option to render Markdown with formatting, images, URLs, and more. Any number of files, such as images and PDFs, can be attached to a note, and notes can also be tagged. I started developing Joplin when Evernote changed its pricing model and because I wanted my 4,000+ notes to be stored in a more open format, free of any proprietary solution. To that end, I have developed three Joplin applications, all under the MIT License: for desktop (Windows, MacOS, and Linux), for mobile (Android and iOS), and for the terminal (Windows, MacOS, and Linux). All the applications have similar user interfaces and can synchronize with each other. They are based on open standards and technologies including SQLite and JavaScript for the backend, and Terminal Kit (Node.js), Electron, and React Native for the three front ends. Read more

Open Source OS Still supporting 32-bit Architecture and Why it’s Important

One after the other, Linux distributions are dropping 32-bit support. Or, to be accurate, they drop support for the Intel x86 32-bit architecture (IA-32). Indeed, computers based on x86_64 hardware (IA-64) are superior in every way to their 32-bits counterpart: they are more powerful, run faster, are more compact, and more energy efficient. Not mentioning their price has considerably decreased in just a few years. If you have the opportunity to switch to 64 bits, do it. But, to quote a mail I received recently from Peter Tribble, author of Tribblix: “[… ] in the developed world we assume that we can replace things; in some parts of the developing world older IA-32 systems are still the norm, with 64-bit being rare.” Read more
