  • AMD Secure Encrypted Virtualization Updated For Linux

    While AMD's new Epyc processors have a new "Secure Encrypted Virtualization" feature, the support isn't yet mainlined in the Linux kernel but is getting closer.

  • Nvidia 384.59 Linux Graphics Driver Adds Support for GeForce GT 1030 GPUs, More

    Nvidia on Monday announced the release of a new long-lived graphics driver for Linux, FreeBSD, and Solaris-based operating systems, versioned 384.59, adding support for new GPUs, along with a bunch of bug fixes and improvements.

    Nvidia 384.59 is now considered the most advanced version of the proprietary graphics driver for GNU/Linux, FreeBSD, and Solaris platforms, which users should install on their personal computers running a supported Nvidia GPU immediately after reading this article.

  • NVIDIA+CMU Develop New Shading Language & Compiler Framework

    NVIDIA and Carnegie Mellon University have developed a new open-source shading language in step with a new compiler framework.

  • RADV Gets More Last Minute Fixes For Mesa 17.2

    David Airlie and Bas Nieuwenhuizen have been landing some more last minute RADV Vulkan driver fixes ahead of the Mesa 17.2 branching.

    As reported this weekend, RADV Is Almost Ready For SteamVR With Mainline Mesa. Besides that, it's been getting some corrections with Mesa 17.2 in addition to performance improvements since 17.1.

  • Mesa 17.2 Has Been Branched

    Mesa release manager Emil Velikov went ahead and branched Mesa 17.2 from Git master with new developments now being for Mesa 17.3.

    Mesa 17.2 is another huge quarterly update for this 3D user-space driver stack and will be released as stable in August. This is a huge update for nearly all of the drivers involved; I'll be around with my usual feature overview/recap shortly. It's been a big stride for both the OpenGL and Vulkan drivers.

  • RADV Is Almost Ready For SteamVR With Mainline Mesa

    Those using Radeon graphics for your Steam VR Linux gaming experience will soon be able to use the mainline Mesa stack with the necessary RADV changes almost all being in place.

    RADV has worked with SteamVR on Linux for some months, but you've had to rely upon a branched version of Mesa that offers all the necessary Vulkan extensions required by SteamVR. The day is finally coming where the mainline open-source Radeon Vulkan driver stack has all those extensions in place, as discussed here.

Ryzen Compiler Performance: Clang 4/5 vs. GCC 6/7/8 Benchmarks

Filed under

A few days back I posted some fresh AMD Ryzen compiler benchmarks of LLVM Clang now that it has its new Znver1 scheduler model, which helps out the performance of Ryzen on Linux with some of the generated binaries tested. But it was found still that Haswell-tuned binaries are sometimes still faster on Ryzen than the Zen "znver1" tuning itself. For continuing our fresh compiler benchmarks from AMD's new Ryzen platform, here are the latest GCC numbers.

  • D3D9 Shaders To SPIR-V For Vulkan Is Being Worked On By VK9
  • Clover OpenCL Gallium3D Sees Some Patches, Closer To OpenCL 1.2

    Community developer and Phoronix reader Aaron Watry has continued providing some much needed attention to Clover, the Gallium3D state tracker implementing OpenCL, notably for R600g/RadeonSI hardware not receiving ROCm OpenCL support.

    Watry has been working on improving the OpenCL compliance of Clover via Khronos' recently-opened OpenCL Conformance Test Suite (CTS). Five patches sent out today fix at least one CTS test while the other patches work on version handling changes. He's also begun experimenting with exposing OpenCL 1.2, but with the patches OpenCL 1.1 remains set.

  • Skylake & Newer Could Still See Faster Linux Graphics Performance

    With my recent tests of Intel Kabylake graphics on Linux 4.13 showing no change in performance, it was asked whether the Intel Linux graphics driver has plateaued for reaching maximum performance. It hasn't.

  • Vulkan 1.0.56 Brings One New Extension, Fixes

    Khronos' SIGGRAPH announcements are coming up in just over one week but today we have the Vulkan 1.0.56 release.

  • Nouveau Gets Thermal Throttling, One Step Closer For GTX 900 Re-Clocking

    Nouveau re-clocking/power expert Karol Herbst has published a set of patches today implementing thermal throttling support for this open-source NVIDIA DRM driver.

  • Mesa 17.2 Merge Window Extended To Sunday, RADV Shared Semaphores Lands

    The merging fun for Mesa 17.2 will continue through the weekend.

    Mesa release manager Emil Velikov has shared rather than going into feature freeze today, he's planning to extend it by a few days. In particular, he's planning to branch now by Sunday evening to allow for some remaining patches to be merged.

  • A small Update

    I planned on writing about the Present extension this week, but I’ll postpone this since I’m currently strongly absorbed into finding the last rough edges of a first patch I can show off. I then hope to get some feedback on this from other developers in the xorg-devel mailing list.

    Another reason is that I stalled my work on the Present extension for now and try to get first my Xwayland code working. My mentor Daniel recommended that to me since the approach I pursued in my work on Present might be more difficult than I first assessed. At least it is something similar to what other way more experienced developers than myself tried in the past and weren’t able to do according to Daniel. My idea was to make Present flip per CRTC only, but this would clash with Pixmaps being linked to the whole screen only. There are no Pixmaps only for CRTCs in X.

  • Revised DRI3 v1.1 Modifiers Support For Mesa

    Daniel Stone of Collabora has published a new set of 14 patches implementing DRI3 v1.1's modifiers support inside Mesa with support for EGL X11 and Vulkan X11/Wayland.

Linux Full Disk Encryption Performance With AMD Ryzen 5 + SATA 3.0 SSD

Filed under

Similar to our past disk encryption benchmarks, a clean install of Fedora Linux (26, with Linux 4.11) was done without any encryption and then again when opting for the full-disk encryption setup via the Anaconda installer. EXT4 was the file-system in use with its default mount options and no other changes were made between the installations or during the benchmarking process.

  • Linus Torvalds: Gadget reviewer

    If you know anything about Linus Torvalds, you know he's the mastermind and overlord of Linux. If you know him at all well, you know he's also an enthusiastic scuba diver and author of SubSurface, a do-it-all dive log program. And, if you know him really well, you'd know, like many other developers, he loves gadgets. Now, he's starting his own gadget review site on Google+: Working Gadgets.

  • Intel Mesa Driver Lands Support For OpenGL ARB_shader_ballot

    Besides testing the Radeon/AMDGPU work in Linux 4.13, here are some fresh benchmarks of Intel Kabylake GT 2 / HD Graphics 630 from this new in-development kernel.

    The Intel kernel graphics driver changes for 4.13 are outlined in our Linux 4.13 feature overview. Using the Intel Core i7 7700K I did some comparison tests of Linux 4.13-rc1 compared to 4.12.0 and 4.11.0 stable.

DRM-Carrying Flash's Death in the News

  • Google: HTML is Faster, Safer, and More Power Efficient Than Adobe's Flash
    After Adobe's big announcement this morning that they plan to end support for Flash in late 2020, Google Chrome's Anthony Laforge published a blog article asking Flash developers to start transitioning to HTML. For a long time, Google shipped its Chrome web browser built-in with Flash support, but it now looks like Chrome will slowly start blocking Flash content, require explicit permission from users, until upstream support is terminated three years from now, at the end of 2020. Google, like anyone else on this planet, believe HTML is faster, safer, and more power efficient than Flash, without a doubt.
  • Adobe Flash will die by 2020, Adobe and browser makers say

    For many, though, Flash was simply seen at least as a nuisance, and at worst a serious security risk.   


    Flash-based exploits have circulated for years, in a game of cat-and-mouse between hackers and Adobe itself. Apple's Steve Jobs famously banned Flash from the iPhone, claiming that Flash hurt battery life and also was a security risk. [...]

  • Adobe Flash is dead (well, nearly)

    Tech firms have long been hammering nail's into its coffin, too, and back in 2010, Steve Jobs famously penned a letter that called for the demise of Adobe Flash in favour of a shift to open web standards.
