  • RadeonSI Compatibility Profile Is Close To OpenGL 4.4 Support

    It was just a few days ago that the OpenGL compatibility profile support in Mesa reached OpenGL 3.3 compliance for RadeonSI while now thanks to the latest batch of patches from one of the Valve Linux developers, it's soon going to hit OpenGL 4.4.

    Legendary open-source graphics driver contributor Timothy Arceri at Valve has posted 11 more patches for advancing RadeonSI's OpenGL compatibility profile support, the alternative context to the OpenGL core profile that allows mixing in deprecated OpenGL functionality. The GL compatibility profile mode is generally used by long-standing workstation software and also a small subset of Linux games.

  • Intel Hyper Threading Performance With A Core i7 On Ubuntu 18.04 LTS

    Following the news yesterday of OpenBSD disabling Intel Hyper Threading by default within its OS over security concerns and plans to disable Simultaneous Multi Threading for other processors/architectures too, here are some fresh Intel HT benchmarks albeit on Ubuntu Linux. The OpenBSD developer involved characterized HT/SMT as "doesn't necessarily have a positive effect on performance; it highly depends on the workload. In all likelihood it will actually slow down most workloads if you have a CPU with more than two cores." So here are some benchmarks using a current-generation Intel Core i7 8700K six-core processor with Hyper Threading.

  • SMT Disabled by Default in -current
  • OpenBSD Will Disable Intel Hyper-Threading To Avoid Spectre-Like Exploits

    OpenBSD, an open source operating system that focuses on security, announced that it will disable Intel’s Hyper-Threading (HT) feature so that attackers can no longer employ Spectre-like cache timing attacks.

  • Intel’s hyperthreading blocked on OpenBSD amid hints of new Spectre-like bugs

    The maintainer of open source Unix-like operating system, OpenBSD, has announced that it will disable hyperthreading on Intel CPUs because of security concerns. It claims that simultaneous multithreading creates a potential new attack vector for Spectre-like exploits, and plans to expand its disabling of multithreading technologies to other chip manufacturers in the near future.

  • AMDGPU DRM Driver To Finally Expose GPU Load Via Sysfs

    The AMDGPU DRM driver appears to finally be crossing the milestone of exposing the current GPU load (as a percentage) in a manner that can be easily queried via sysfs.

    For years I've been frustrated via the lack of standardization of sysfs/debugfs files among the DRM drivers and some seemingly basic information not being exposed in such a manner that easily benefits various desktop plug-ins, those wanting to script basic monitors/checks/etc around such outputs, and use-cases like with the Phoronix Test Suite for easily querying this information too for its sensor recording. One of the frustrations with the Radeon Linux stack has been that there wasn't a trivial way to read the GPU load usage as a percentage... There's been ways if installing third-party utilities like RadeonTool, but no universal solution nor one that doesn't require root and would be widely available.

  • Radeon Software 18.20 Stable Released With Official Ubuntu 18.04 LTS Support

    The Radeon Software "AMDGPU-PRO" 18.20 hybrid driver stack is now available with official support for Ubuntu 18.04 LTS and Red Hat Enterprise Linux 17.20.

    End of support for Apple’s OpenGL programming interface could pull the plug on molecular modelling software

    Researchers are voicing concerns over a move that may affect many 3D visualisation programs that are commonly used in computational research.

    Apple’s Macintosh operating systems (macOS) is set to end support for OpenGL, the programming interface frequently used to display 3D graphics in medical and scientific visualisation software, which has existed since 1992. Nearly all open source and commercial chemistry visualisation programs that are used to display atoms, molecules, bonds and protein ribbons – such as Mercury, VMD and PyMOL – use the system.

  • Vulkan Display Extensions To Be Used By SteamVR Merged Into Mesa RADV/ANV

    Keith Packard's long in development work for improving the Linux display stack infrastructure for better dealing with VR head-mounted displays is about rounded out with the new Vulkan extension support being merged into Mesa.

    Just over a year ago famed X developer Keith Packard started contract work for Valve to improve the plumbing around the Linux/X.Org support for virtual reality HMDs for better performance and better integration. Within the Linux kernel and the X.Org Server he's worked and landed the DRM leasing support of outputs to let a VR compositor (Steam VR) have direct access to the output, "non-desktop" quirk handling so VR HMDs don't become mapped as part of a standard Linux desktop, and related work.

  • A Session Suspension & Restoration Protocol Proposed For Wayland

    KDE Wayland developer Roman Gilg who started contributing to Wayland via last year's Google Summer of Code is proposing a new Wayland protocol for dealing with desktop session suspension and restoration.

    This protocol extension would allow for more efficient support for client session suspension and restoration such as when you are logging out of your desktop session and want the windows restored at next log-in or if you are suspending your system. While Roman Gilg is working on this protocol with his KDE hat on, he has been talking with Sway and GNOME developers too for ensuring this protocol could work out for their needs.

  • RadeonSI Lands OpenGL 3.3 Compatibility Profile Support

  • Linux literally loses its Lustre – HPC filesystem ditched in new kernel

    Linux has literally lost its Lustre – the filesystem favoured by HPC types has vanished in the first release candidate of version 4.18 of the Linux kernel.

    Linus Torvalds’ announcement of the new release lauds the fact it’s shrunk markedly, much of which can be attributed to the removal of Lustre.

    “The removal of Lustre may not be all that notable, because it does look like a lot of the development has been happening out of tree, which may be why it never really ended up working as well as people hoped in the staging tree,” Torvalds wrote. “ Greg [ Kroah-Hartman] clearly got pretty frustrated about it, so now it's gone.”

    How frustrated? Kroah-Hartman explained Lustre's omission by saying it has "been in the kernel tree for over 5 years now" but "has not really moved forward into the 'this is in shape to get out of staging' despite many half-completed attempts."

  • OpenGL Floating Point Textures No Longer Encumbered By Patents, Enabled In Mesa

    Back in 2012 when talking with Gabe Newell of Valve about open-source/Linux challenges one of the topics he was awed about was patents encumbering the open-source graphics driver progress. Six years later, Timothy Arceri working on the Valve Linux graphics driver team has freed Mesa's ARB_texture_float support from being built conditionally due to these patent fears.

  • Vulkan 1.1.78 Released With Various Issues Resolved

    I’ve been tinkering with a few modern podcast players in the past few months. CPod, Vocal and Winds all use modern web technologies; in the case of CPod and Winds a combination of JavaScript weaved with the Electron framework. It’s only fair to take a different tack. castero differs fundamentally — it’s a command line podcast client. It’s designed to be easy to use and targeted at users who want lightweight command line applications instead of bloated GUI-based alternatives. castero lets you add podcasts via RSS feeds, and handles a large number of feeds. It’s released under an open source license. The software is written in the Python programming language.

  • Intel Has Quietly Been Working On A New Gallium3D Driver Being Called "Iris"
    After resisting Gallium3D for the past decade with a preference on continuing to maintain their "i965" Mesa classic driver and all they've invested into its compiler stack and more, it seems times are changing as the open-source Intel team has been starting up development of a modern Gallium3D driver. This is not to be confused with the former i915g or i965g efforts from about a decade ago that were the experiments of Tungsten/LunarG for driver research/experimentation purposes or in the case of i915g to handle some features with LLVM in software, but this is a modern Gallium3D driver targeting their current hardware.
