  • Vulkan-CPU Has Working SPIR-V To LLVM IR Translation, x86 Code Almost Working

    Jacob Lifshay, the student developer via GSoC 2017 working on a Vulkan CPU-based implementation to essentially serve as a software renderer that is making use of LLVM, now has working SPIR-V to LLVM IR translation.

    SPIR-V, of course, being the intermediate representation used by Vulkan and OpenCL 2.1+. Jacob's work is separate from the other SPIR-V LLVM work being pursued by other parties. Lifshay has now implemented enough of a SPIR-V to LLVM IR translator that it can translate simple shaders onwards to LLVM IR. He also says he is almost at a stage where in turn it can then generate x86 machine code. So in the end it will go from SPIR-V shaders to x86 code that can be executed by the CPU.

  • Mesa 17.2 Is Measuring In As One Of The Largest Releases Ever

    Mesa 17.2 is coming in as one of the largest updates ever to Mesa 3D, at least in terms of code delta.

    Out of curiosity given the recent branching and release candidate, I used Git to compare the code size of the 17.1 branch to 17.2.

    The Etnaviv open-source driver stack that provides reverse-engineered graphics driver support for Vivante graphics cores is working now not only on conventional Linux distributions but also Android environments.

    Collabora has been working on some improvements in this space and a few days ago recapped some of the highlights going into Etnaviv for i.MX6 and Android.

Kernel: CPU scheduler, Codethink, Civil Infrastructure Platform, libinput and Linux Plumbers 2017

  • Reconsidering the scheduler's wake_wide() heuristic

    The kernel's CPU scheduler is charged with choosing which task to run next, but also with deciding where in a multi-CPU system that task should run. As is often the case, that choice comes down to heuristics — rules of thumb codifying the developers' experience of what tends to work best. One key task-placement heuristic has been in place since 2015, but a recent discussion suggests that it may need to be revisited.

    Scheduler wakeups happen all the time. Tasks will often wait for an event (e.g. timer expiration, POSIX signal, futex() system call, etc.); a wakeup is sent when the event occurs and the waiting task resumes execution. The scheduler's job is to find the best CPU to run the task being woken. Making the correct choice is crucial for performance. Some message-passing workloads benefit from running tasks on the same CPU, for example; the pipetest micro-benchmark is a simple model of that kind of workload. Pipetest uses two communicating tasks that take turns sending and receiving messages; the tasks never need to run in parallel and thus perform best if their data is in the cache of a single CPU.

  • libinput and button debouncing

    A few days ago, I pushed code for button debouncing into libinput, scheduled for libinput 1.9. What is button debouncing you ask? Well, I'm glad you asked, because otherwise typing this blog post would've been a waste of time Smile

    Over in Utopia, when you press the button on a device, you get a press event from the hardware. When you release said button, you get a release event from the hardware. Together, they form the button click interaction we have come to learn and love over the last couple of decades. Life is generally merry and the sunshine to rainbow to lollipop ratio is good. Meanwhile, over here in the real world, buttons can be quite dodgy, don't always work like they're supposed to, lollipops are unhealthy and boy, have you seen that sunburn the sunshine gave me? One way how buttons may not work is that they can lose contact for a fraction of a second and send release events even though the button is being held down. The device usually detects that the button is still being down in the next hardware cycle (~8ms on most devices) and thus sends another button press.

  • [Older] Containers micro-conference at Linux Plumbers 2017

    This year's edition of the Linux Plumbers Conference will once again feature a containers micro-conference. This is a great occasion for users and developers of Linux container technology to meet and talk about the feature.

  • CRYENGINE 5.4 Preview released, includes Vulkan support

    The CRYENGINE 5.4 Preview has been released and it comes with something truly interesting: Vulkan support.

  • CRYENGINE 5.4 Preview released today, including over 620 improvements

    The CRYENGINE 5.4 Preview is a major update which couldn’t have been achieved without all of the feedback from the CRYENGINE community. There are several major advancements and integrations that we think will make things more accessible and let you achieve even more, more rapidly.

  • Dev snapshot: Godot 3.0 alpha1

    After almost one year of development, the master branch (future Godot 3.0) is mostly feature-complete and ready for broader testing by the Godot community. We are therefore releasing a first alpha snapshot for existing users to play with and report bugs.

  • Godot 3.0 Reaches Alpha

    As of now there is no time table for the stable Godot 3.0 release besides "when it's ready." Godot 3.0 doesn't have a Vulkan renderer but just has its revamped OpenGL ES 3.0 / OpenGL 3.3 support.

Wikileaks Releases Spy Files Russia, CCleaner Infected, Equifax Has a Dirty Little Secret

  • Spy Files Russia
    This publication continues WikiLeaks' Spy Files series with releases about surveillance contractors in Russia. While the surveillance of communication traffic is a global phenomena, the legal and technological framework of its operation is different for each country. Russia's laws - especially the new Yarovaya Law - make literally no distinction between Lawful Interception and mass surveillance by state intelligence authorities (SIAs) without court orders. Russian communication providers are required by Russian law to install the so-called SORM ( Система Оперативно-Розыскных Мероприятий) components for surveillance provided by the FSB at their own expense. The SORM infrastructure is developed and deployed in Russia with close cooperation between the FSB, the Interior Ministry of Russia and Russian surveillance contractors.
  • Malware-Infected CCleaner Installer Distributed to Users Via Official Servers for a Month
    Hackers have managed to embed malware into the installer of CCleaner, a popular Windows system optimization tool with over 2 billion downloads to date. The rogue package was distributed through official channels for almost a month. CCleaner is a utilities program that is used to delete temporary internet files such as cookies, empty the Recycling Bin, correct problems with the Windows Registry, among other tasks. First released in 2003, it has become hugely popular; up to 20 million people download it per month. Users who downloaded and installed CCleaner or CCleaner Cloud between Aug. 15 and Sept. 12 should scan their computers for malware and update their apps. The 32-bit versions of CCleaner v5.33.6162 and CCleaner Cloud v1.07.3191 were affected.

    Phoronix have been hard at work testing out AMD's new server chip, specifically the 2.2/2.7/3.2GHz EPYC 7601 with 32 physical cores.  The frequency numbers now have a third member which is the top frequency all 32 cores can hit simultaneously, for this processor that would be 2.7GHz.  Benchmarking server processors is somewhat different from testing consumer CPUs, gaming performance is not as important as dealing with specific productivity applications.   Phoronix started their testing of EPYC, in both NUMA and non-NUMA configurations, comparing against several Xeon models and the performance delta is quite impressive, sometimes leaving even a system with dual Xeon Gold 6138's in the dust.  They also followed up with a look at how EPYC compares to Opteron, AMD's last server offerings.  The evolution is something to behold.
