  • "Soft" FP64/INT64 Implementations Merged To Mesa, Intel Driver Already Making Use

    For those with older graphics processors, rejoice as with the upcoming Mesa 19.0 driver release it might now be possible to have OpenGL 4.0 thanks to software-based implementations of ARB_gpu_shader_int64 and ARB_gpu_shader_fp64 finally being merged to mainline. The FP64 one is most notable with that being a requirement for OpenGL 4.0 but some older GPUs lacking that capability for bumping past OpenGL 3.3.

    Going back to the summer of 2016 was a Google Summer of Code project by Elie Tournier to implement "soft" FP64 support using GLSL to help out older GPUs that otherwise couldn't expose OpenGL 4.0 due to not supporting ARB_gpu_shader_fp64. Elie Tournier has since gone on to work for Collabora but getting this code merged has taken quite some time.

  • Intel Developer Working On Adding HDR Display Support To Wayland / Weston

    While the Linux desktop's display stack has largely reached parity with Windows and macOS in recent years (most recently, the DRM core properties hitting Linux 5.0 around Adaptive-Sync / VRR), but one of the areas that has remained elusive has been for full HDR display support. We've seen NVIDIA working on nursing the X.Org-based display stack for HDR while now Intel appears to be working on the necessary Wayland changes.

    Back in 2016 is when NVIDIA began looking at the Linux shortcomings for HDR display support and ended up proposing the DeepColor X11 extension (still yet to be merged) and other efforts for an HDR Linux desktop compared to traditional SDR content. Now with Intel's Icelake processors coming out later in the year with "Gen 11" graphics and their Xe discrete graphics potentially coming next year, HDR display support is now on the minds of their open-source driver developers.

  • The Expected Linux Driver State For The Radeon VII

    With yesterday's surprise announcement of the Radeon VII "Radeon 7" as a new $699 7nm second-generation Vega consumer graphics card launching in early February, you may be wondering about the open-source Linux driver support state. While nothing official has come down the wire yet, here is what appears to be the state for this new Vega graphics card on Linux.

    AMD hasn't communicated yet about the Linux driver support for Radeon VII, I don't have any review sample or the like at this time, but given the number of questions since yesterday about Linux support, here's what I know based off my close monitoring of the AMD open-source Linux driver development.

Android Low-Memory Killer--In or Out?

One of the jobs of the Linux kernel—and all operating system kernels—is to manage the resources available to the system. When those resources get used up, what should it do? If the resource is RAM, there's not much choice. It's not feasible to take over the behavior of any piece of user software, understand what that software does, and make it more memory-efficient. Instead, the kernel has very little choice but to try to identify the software that is most responsible for using up the system's RAM and kill that process. The official kernel does this with its OOM (out-of-memory) killer. But, Linux descendants like Android want a little more—they want to perform a similar form of garbage collection, but while the system is still fully responsive. They want a low-memory killer that doesn't wait until the last possible moment to terminate an app. The unspoken assumption is that phone apps are not so likely to run crucial systems like heart-lung machines or nuclear fusion reactors, so one running process (more or less) doesn't really matter on an Android machine.

Security Leftovers

  • Microsoft & Pentagon are quietly hijacking US elections (by Lee Camp)
    Good news, folks! We have found the answer to the American rigged and rotten election system. The most trustworthy of corporations recently announced it is going to selflessly and patriotically secure our elections. It’s a small company run by vegans and powered by love. It goes by the name “Microsoft.” (You’re forgiven for never having heard of it.) The recent headlines were grandiose and thrilling: “Microsoft offers software tools to secure elections.” “Microsoft aims to modernize and secure voting with ElectionGuard.” Could anything be safer than software christened “ElectionGuard™”?! It has “guard” right there in the name. It’s as strong and trustworthy as the little-known Crotch Guard™ – an actual oil meant to be sprayed on one’s junk. I’m unclear as to why one sprays it on one’s junk, but perhaps it’s to secure your erections? (Because they’ve been micro-soft?)
  • Netflix Researchers Just Fixed 4 Severe Linux And FreeBSD Vulnerabilities
  • Netflix Uncovers TCP Bugs Within The Linux & FreeBSD Kernels
    As Netflix's first security bulletin for 2019, they warned of TCP-based remote denial of service vulnerabilities affecting both Linux and FreeBSD. These vulnerabilities are rated "critical" but already being corrected within the latest Git code.

Games: Project Zero Deaths, Littlewood, Ravenfield, ENCODYA

  • Project Zero Deaths, a new free to play online platform shooter has Linux support
    A free game to start the day with, as the multiplayer platform shooter Project Zero Deaths recently entered Early Access and it includes Linux support.
  • The peaceful building RPG 'Littlewood' is now available in Early Access with Linux same-day support
    Littlewood from developer Sean Young arrived on Steam in Early Access today and it looks like a very promising and peaceful RPG. Funded thanks to the help of nearly four thousand people on Kickstarter, Littlewood is set after the world has been saved and you're the hero tasked with rebuilding a town.
  • Ravenfield, the fun single-player FPS now has a built-in map editor and destructible object support
    The amount of content being added into Ravenfield is quite impressive and now anyone can easily make their own maps for it, without the need of Unity. Early Access Build 16 went live recently, with a custom-made map editor that works on Linux and it's surprisingly easy to use. You no longer need the Ravenfield mod tools for Unity, making it far more accessible. It comes with all of the official Ravenfield props, meaning you can place down all sorts of things. When ready, it also has Steam Workshop support built in for you to publish it.
  • Science Fiction point-and-click Encodya has a demo released, will go to Kickstarter
    The background story of the upcoming science fiction point and click game Encodya is the Kickstarter campaign for the animation short movie Robot Will Protect You. Getting over 23.000€ from an initial target of 8.750€, it reached several stretch goals, the last one being "We'll start developing a game!". And so they did... The game, named "ENCODYA", grabbed my attention in a Facebook group about point and click adventures. Drawn by the art, I asked if a Linux version would be possible. Indeed it was, and I was asked if I could test it. As it's using Unity, I expected it to a) fail on trying to play a video, b) show graphical problems or c) just run like the Windows version. First a) it was. But the author was eager to make the Linux version and a fix was attempted. After struggling with finding the right output options for the studio's intro video, we found that everything seems to be working just like on Windows. So Hooray for the game engines supporting the OS of our choice!
