  • Google & Collabora Working On OpenGL ES 2.0 Virtualized GPU Access For Containers

    Robert Foss of Collabora has shared some work they are engaged in with Google for virtualizing GPU access and allowing for OpenGL ES 2.0 acceleration for containers.

  • Wayland 1.15 & Weston 4.0 Now Planned For Release In April

    Wayland 1.15 and the Weston 4.0 compositor had been planned for release in February but Wayland developers decided there was still enough material on the verge of landing that they decided to delay the release. A new release schedule has now been put forward for getting these updates out in April.

    Derek Foreman of the Samsung OSG has stepped up to manage this revised Wayland 1.15 / Weston 4.0 release. Now that the "high priority" work has been merged, Derek is ready to move on with wrangling the release.

  • Xorgproto 2018.2 Released To Fix The Fallout Of This New X.Org Package

    Last week marked the inaugural release of Xorgproto, a new package consisting of all the X.Org protocol headers rather than being in standalone packages now that X.Org Server development is slowing down and that many of these protocol headers wind up getting updated at the same time. Today marks the Xorgproto 2018.2 release.

  • 34 More Patches Roll Out For AMDGPU DC With Raven Ridge Fixes Plus Color Management

    Open-source AMD Linux driver developers have started off the week by posting 34 more patches for the "DC" display code stack that was mainlined in Linux 4.15 and further improved with Linux 4.16. With these latest patches that begin the queue for Linux 4.17 there are yet more AMDGPU DC improvements and in particular Raven Ridge fixes.

  • Freedreno Gallium3D Tackling NIR Optimizations & More In 2018

    Freedreno project leader Rob Clark who is employed by Red Hat has provided a status update on his activities around this reverse-engineered, open-source Qualcomm Adreno graphics driver.

  • AMD's first Ryzen Desktop APUs with Vega graphics are now available

    AMD has announced today the worldwide release of their first Ryzen Desktop APUs with Vega graphics, could be an interesting choice for low-cost Linux gaming.

FreeBSD 12.0-RC1 Released, Fixes Ryzen 2 Temperature Reporting

Arguably most user-facing with this week's FreeBSD 12.0-RC1 release is updating the amdsmn/amdtemp drivers for attaching to Ryzen 2 host bridges. Additionally, the amdtemp driver has been fixed for correctly reporting the AMD Ryzen Threadripper 2990WX core temperature. The 2990WX temperature reporting is the same fix Linux initially needed to for a 27 degree offset to report the correct temperature. It's just taken FreeBSD longer to add Ryzen 2 / Threadripper 2 temperature bits even though they had beat the Linux kernel crew with the initial Zen CPU temperature reporting last year.

GPU/Graphics: DRM/KMS and CUDA

  • Google's Pixel 3 Is Using The MSM DRM Driver, More Android Phones Moving To DRM/KMS Code
    It turns out Google's recently announced Pixel 3 smartphone is making use of the MSM Direct Rendering Manager driver associated with the Freedreno open-source Qualcomm graphics project. Google is also getting more Android vendors moving over to using DRM/KMS drivers to power their graphics/display. Alistair Strachan of Google presented at this week's Linux Plumbers Conference and the growing adoption of Direct Rendering Manager / Kernel Mode-Setting drivers by Android devices.
  • Red Hat Developers Working Towards A Vendor-Neutral Compute Stack To Take On NVIDIA's CUDA
    At this week's Linux Plumbers Conference, David Airlie began talking about the possibility of a vendor-neutral compute stack across Intel, Radeon, and NVIDIA GPU platforms that could potentially take on NVIDIA's CUDA dominance. There has been the work on open-source NVIDIA (Nouveau) SPIR-V compute support all year and that's ongoing with not yet having reached mainline Mesa. That effort has been largely worked on by Karol Herbst and Rob Clark, both open-source GPU driver developers at Red Hat. There has also been other compute-motivated open-source driver/infrastructure work out of Red Hat like Jerome Glisse's ongoing kernel work around Heterogeneous Memory Management (HMM). There's also been the Radeon RADV driver that Red Hat's David Airlie co-founded and continues contributing significantly to its advancement. And then there has been other graphics/compute contributions too with Red Hat remaining one of the largest upstream contributors to the ecosystem.

Endless OS Switching To The BFQ I/O Scheduler For More Responsive Linux Desktop

While Con Kolivas' kernel patch series decided to do away with BFQ support, the GNOME-aligned Endless OS Linux distribution has decided to do the opposite in move from CFQ as the default I/O scheduler over to BFQ. Endless OS has decided to switch to the BFQ (Budget Fair Queuing) I/O scheduler since it prioritizes interactive workloads and should make for a better experience for its users particularly when applications may be upgrading in the background. During heavy background I/O, Endless found that their launch time of LibreOffice went from taking 16 seconds with CFQ to just three seconds when using BFQ. Other tests were also positive for improving the interactivity/responsiveness of the system particularly during heavy background I/O. Read more

Goa to train teachers in new open-source software apps for cyber security

After working with Google India for wider adoption of internet safety in schools two years ago, Goa education agencies will implement another project to train computer, information and communication technology school and higher secondary teachers in new open-source software applications for cyber security integration. The State Board of Secondary and Higher Secondary Education and Goa State Council Educational Research and Training (GSCERT) have decided to begin the second programme with over 650 computer teachers from December 4 to 18, Mr. Ajay Jadhav, Board of Study member and coordinator of the first project with Google, said on Friday. The cyber security training syllabus has been worked out and 18 resource persons are ready for the project. Read more
