  • Glxinfo Gets Updated With OpenGL 4.6 Support, More vRAM Reporting

    The glxinfo utility is handy for Linux users in checking on their OpenGL driver in use by their system and related information. But it's not often that glxinfo itself gets updated, except that changed today with the release of mesa-demos-8.4.0 as the package providing this information utility.

    Mesa-demos is the collection of glxinfo, eglinfo, glxgears, and utilities related to Mesa. With the Mesa-demos 8.4.0 it is predominantly glxinfo updates.

  • Intel ANV Getting VK_KHR_16bit_storage Support Wrapped Up

    Igalia's Jose Maria Casanova Crespo sent out a set of patches today for fixes that allow for the enabling of the VK_KHR_16bit_storage extension within Intel's ANV Vulkan driver.

    The patches are here for those interested in 16-bit storage support in Vulkan. This flips on the features for storageBuffer16BitAccess, uniformAndStorageBuffer16BitAccess, storagePushConstant16 and the VK_KHR_16bit_storage extension. This support is present for Intel "Gen 8" Broadwell graphics and newer. Hopefully the work will be landing in Mesa Git soon.

  • SPIR-V Support For Gallium3D's Clover Is Closer To Reality

    It's been a busy past week for open-source GPU compute with Intel opening up their new NEO OpenCL stack, Karol Herbst at Red Hat posting the latest on Nouveau NIR support for SPIR-V compute, and now longtime Nouveau contributor Pierre Moreau has presented his latest for SPIR-V Clover support.

    Pierre has been spending about the past year adding SPIR-V support to Gallium3D's "Clover" OpenCL state tracker. SPIR-V, of course, is the intermediate representation used now by OpenCL and Vulkan.

Radeon Linux OpenGL Driver Continues Giving Its Best Against Windows 10

Filed under
Graphics/Benchmarks

With having around a Windows 10 installation this week for the latest Windows 10 WSL vs. Linux benchmarking, I also carried out some fresh benchmarks of the Radeon gaming performance between Windows 10 and Ubuntu Linux using the very latest drivers on each platform. This time around a Radeon RX 580 and RX Vega 64 were used for this benchmarking.

  • Development On The Chai Mali T700 Open-Source GPU Driver To Resume

    Last year we covered the work on the project "Chai" as an open-source, reverse-engineered driver for Mali T700 series. After a hiatus, the lead developer is back working on the project.

    The developer on the project was previously just known as "Cafe Beverage", but this developer has come out today as Alyssa Rosenzweig.

  • Nouveau's NIR Support Inches Closer To TGSI Quality

    Longtime Nouveau contributor Karol Herbst joined Red Hat at the end of last year where his current task is on NIR intermediate representation support for Nouveau as part of bringing SPIR-V compute support to this open-source NVIDIA Linux driver.

  • Intel GLSL On-Disk Shader Cache Enabled By Default

    For Mesa 18.0 is the initial Intel shader cache support for archiving compiled GLSL shaders on-disk to speed up the load times of subsequent game loads and other benefits. For the Mesa 18.0 release the functionality isn't enabled by default but it will be for Mesa 18.1.

  • Xorgproto 2018.3 Brings RandR Leasing + Non-Desktop Monitors

    Xorgproto debuted earlier this month as a centralized package of all X.Org protocol headers that used to be versioned and developed independently. Given the slower development now of the xorg-server and lots of the protocols being intertwined, they are now all bundled together. Tuesday marked the 2018.3 release with the new additions for Keith Packard's SteamVR Linux infrastructure work.

    Xorgproto 2018.3 offers up the protocol changes for the X.Org Server work that Keith Packard has been doing on improving the virtual reality head-mounted display (VR HMD) support for Linux systems, particularly around SteamVR. The X.Org protocol changes needed are supporting RandR leasing of outputs and also non-desktop monitor handling, so the VR HMD won't be treated as a conventional display and the Linux desktop systems then attempt to make use of it thinking it's just another HDMI/DP display.

  • Even With AMDGPU DC, HDMI/DP Audio Isn't Working Out For All Radeon Linux Users

    While the newly-released Raven Ridge APUs could make for nice HTPC systems given the number of compatible mini-ITX/micro-ATX motherboards and these 65 Watt APUs offering Zen CPU cores with Vega graphics, besides the current problematic Raven Ridge graphics support, there are still some broader AMDGPU DC audio problems for newer graphics cards.

    Phoronix reader Fred wrote in today to call attention to the AMDGPU DC audio situation. While AMDGPU DC was merged in Linux 4.15 and provides HDMI/DP audio support to the past few generations of Radeon GPUs on this new display code stack, not all audio formats play nicely.

Graphics/Benchmarks
  • New Wine-Vulkan Patches Are Under Review

    Roderick Colenbrander's Wine-Vulkan work for Vulkan infrastructure support under Wine has been updated and is ready for review, making these initial bits a candidate for soon being incorporated into mainline Wine.

    Roderick has spent the past few months on the Vulkan infrastructure for Wine as a Vulkan layer with ICD driver support rather than the older Vulkan library (non-ICD implementation) found in Wine-Staging.

  • Vulkan 1.0.69 Released With Fixes & New AMD Buffer Marker Extension

    While waiting to see what Khronos could have in store for GDC 2018 next month around Vulkan, today marks the Vulkan 1.0.69 point release availability.

    With Vulkan 1.0.68 having shipped in the middle of January, there are a fair amount of documentation improvements/fixes over the past month. As usual, addressing issues with the documentation reflects a majority of the changes for these point releases. Of the issues addressed in Vulkan 1.0.69, it's mostly a collection of over a dozen minor problems.

  • Vega Gets Its Last Fix For Dawn of War III On Linux With Vulkan

    Samuel Pitoiset of Valve has worked through the last of the Dawn of War 3 issues for Radeon Vega GPUs with the RADV Vulkan driver.

  • RadeonSI Now Offers NIR Shader Cache Support

    Earlier this month Valve Linux GPU driver developer Timothy Arceri landed NIR shader caching support within the Gallium3D Mesa state tracker as an alternative to the existing TGSI IR caching support. Arceri has now worked through implementing this NIR cache support for the RadeonSI driver.

  • mesa 17.3.5

    This is a emergency release fixing major a issue in the RADV driver.

  • Mesa 17.3.5 Released To Fix A RADV Bug

    While Mesa 17.3.4 was just released a few days ago with 90+ changes, Mesa 17.3.5 is now available as a quick follow-up release due to a serious bug.

An Early Look At Linux 4.16 Performance On Five Systems

Filed under
Graphics/Benchmarks

Here are some preliminary benchmarks of the Linux 4.16 development kernel compared to Linux 4.15 stable on five different systems.

Last week I began testing out the Linux 4.16 kernel on a few different boxes and it's been going rather well (sans the ongoing AMD Raven Ridge Linux issues...). For some initial Linux 4.16 kernel benchmarks I have results today to share for a Core i5 6600K, Core i7 6800K, Xeon E3-1280 v5, Core i9 7980XE, and Ryzen 7 1800X as a few of the available boxes for testing. Tests on other hardware and a greater variety of tests will be coming in the days and weeks ahead as Linux 4.16 continues to stabilize.

  • Nouveau Gets ARB_bindless_texture Support For Maxwell & Newer

    Back for Mesa 18.0 there was OpenGL bindless textures for Kepler GPUs on the open-source NVIDIA "Nouveau" driver while now for Mesa 18.1 that support is in place for Maxwell GPUs and newer.

    Bindless texture support is important for "AZDO" purposes for approaching zero driver overhead with OpenGL. ARB_bindless_texture reduces the API/GL driver overhead of resource bindings and allows accessing textures without needing to first bind/re-bind them.

  • Marek Working Towards Even Lower SGPR Register Usage

    Yesterday well known open-source AMD developer Marek Olšák landed his RadeonSI 32-bit pointers support for freeing up some scalar general purpose registers (SGPRs) and he's continued with a new patch series to alleviate register usage even more.

  • Libdrm 2.4.90 Released With Meson Build System, AMDGPU & Intel Improvements

    Marek Olšák on Saturday released the big libdrm 2.4.90 DRM library update that sits between Mesa and other GPU user-space components and the kernel's Direct Rendering Manager code.

  • Mesa Git Lands RadeonSI 32-bit Pointers Support

    At the start of the new year Marek Olšák of AMD posted a set of patches for 32-bit GPU pointers in RadeonSI. That work has now landed in mainline Mesa Git.

  • xf86-video-vesa 2.4.0

    Nothing terribly exciting, but enough bug fixes to justify a release.

  • VESA X.Org Driver Sees First Update In Three Years

    Should you find yourself using the xf86-video-vesa DDX for one reason or another, a new release is now available and it's the first in three years.

    The xf86-video-vesa 2.4.0 X.Org driver was released this week with the handful of commits that came in since v2.3.4 was tagged three years ago, it's been eight years already since xf86-video-vesa 2.3.0. For most users, xf86-video-vesa is just used in select fallback instances when your main DDX driver fails but even still these days KMS is pretty solid with xf86-video-modesetting, fbdev and other DDX drivers working well, etc.

GNOME and Fedora

  • RFC: Integrating rsvg-rs into librsvg
    I have started an RFC to integrate rsvg-rs into librsvg. rsvg-rs is the Rust binding to librsvg. Like the gtk-rs bindings, it gets generated from a pre-built GIR file.
  • 1+ year of Fedora and GNOME hardware enablement
    A year and a couple of months ago, Christian Schaller asked me to pivot a little bit from working full time on Fleet Commander to manage a new team we were building to work on client hardware enablement for Fedora and GNOME with an emphasis on upstream. The idea was to fill the gap in the organization where nobody really owned the problem of bringing up new client hardware features vertically across the stack (from shell down to the kernel), or rather, ensure Fedora and GNOME both work great on modern laptops. Part of that deal was to take over the bootloader and start working closer to customers and hardware manufacturing parnters.
  • Fedora Atomic Workstation: Works on the beach
    My trip is getting really close, so I decided to upgrade my system to rawhide. Wait, what ? That is usually what everybody would tell you not to do. Rawhide has this reputation for frequent breakage, and who knows if my apps will work any given day. Not something you want to deal with while traveling.

Why You Shouldn’t Use Firefox Forks (and Proprietary Opera)

  • Why You Shouldn’t Use Firefox Forks Like Waterfox, Pale Moon, or Basilisk
    Mozilla Firefox is an open source project, so anyone can take its code, modify it, and release a new browser. That’s what Waterfox, Pale Moon, and Basilisk are—alternative browsers based on the Firefox code. But we recommend against using any of them.
  • Opera Says Its Next Opera Release Will Have the Fastest Ad Blocker on the Block
    Opera Software promoted today its upcoming Opera 52 web browser to the beta channel claiming that it has the faster ad blocker on the market compared to previous Opera release and Google Chrome. One of the key highlights of the Opera 52 release will be the improved performance of the built-in ad blocker as Opera claims to have enhanced the string matching algorithm of the ad blocker to make it open web pages that contain ads much faster than before, and, apparently than other web browsers, such as Chrome.

Security: Updates, Tinder, FUD and KPTI Meltdown Mitigation

  • Security updates for Friday
  • Tinder vulnerability let hackers [sic] take over accounts with just a phone number

    The attack worked by exploiting two separate vulnerabilities: one in Tinder and another in Facebook’s Account Kit system, which Tinder uses to manage logins. The Account Kit vulnerability exposed users’ access tokens (also called an “aks” token), making them accessible through a simple API request with an associated phone number.

  • PSA: Improperly Secured Linux Servers Targeted with Chaos Backdoor [Ed: Drama queen once again (second time in a week almost) compares compromised GNU/Linux boxes to "back doors"]
    Hackers are using SSH brute-force attacks to take over Linux systems secured with weak passwords and are deploying a backdoor named Chaos. Attacks with this malware have been spotted since June, last year. They have been recently documented and broken down in a GoSecure report.
  • Another Potential Performance Optimization For KPTI Meltdown Mitigation
    Now that the dust is beginning to settle around the Meltdown and Spectre mitigation techniques on the major operating systems, in the weeks and months ahead we are likely to see more performance optimizations come to help offset the performance penalties incurred by mitigations like kernel page table isolation (KPTI) and Retpolines. This week a new patch series was published that may help with KPTI performance.
