  • 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.

    Two months after the debut of the Ubuntu 18.04 LTS "Bionic Beaver" release, the Q2'2018 Radeon Sotware for Linux driver update has arrived with support for this latest long-term support release. Radeon Software 18.20 was officially released last week but seemingly went under everyone's radar until now.

  • Chemists criticise mooted shutdown of 3D visualisation tools

    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

GNU Make, FSFE Newsletter, and FSF's BLAG Removal

  • Linux Fu: The Great Power of Make
    Over the years, Linux (well, the operating system that is commonly known as Linux which is the Linux kernel and the GNU tools) has become much more complicated than its Unix roots. That’s inevitable, of course. However, it means old-timers get to slowly grow into new features while new people have to learn all in one gulp. A good example of this is how software is typically built on a Linux system. Fundamentally, most projects use make — a program that tries to be smart about running compiles. This was especially important when your 100 MHz CPU connected to a very slow disk drive would take a day to build a significant piece of software. On the face of it, make is pretty simple. But today, looking at a typical makefile will give you a headache, and many projects use an abstraction over make that further obscures things.

    We recently updated our list of free GNU/Linux distributions to add a "Historical" section. BLAG Linux and GNU, based on Fedora, joined the list many years ago. But the maintainers no longer believe they can keep things running at this time. As such, they requested that they be removed from our list. The list helps users to find operating systems that come with only free software and documentation, and that do not promote any nonfree software. Being added to the list means that a distribution has gone through a rigorous screening process, and is dedicated to diligently fixing any freedom issues that may arise.

Servers: Kubernetes, Oracle's Cloudwashing and Embrace of ARM

  • Bloomberg Eschews Vendors For Direct Kubernetes Involvement
    Rather than use a managed Kubernetes service or employ an outsourced provider, Bloomberg has chosen to invest in deep Kubernetes expertise and keep the skills in-house. Like many enterprise organizations, Bloomberg originally went looking for an off-the-shelf approach before settling on the decision to get involved more deeply with the open source project directly. "We started looking at Kubernetes a little over two years ago," said Steven Bower, Data and Infrastructure Lead at Bloomberg. ... "It's a great execution environment for data science," says Bower. "The real Aha! moment for us was when we realized that not only does it have all these great base primitives like pods and replica sets, but you can also define your own primitives and custom controllers that use them."
