Mark Shuttleworth Comments Following Ubuntu Community Friction, Uncertainty

For the past number of weeks there have been discussions ongoing about the "loss of leadership" within the Ubuntu community and as part of that the Ubuntu Community Team and Ubuntu Community Council having faded away in recent years. Following a lot of comments on the Ubuntu Discourse, Mark Shuttleworth has chimed in with his thoughts and work moving forward.

Within this thread have been views from community participants of Ubuntu interacting great with the community and not so much. Some have pointed to Ubuntu's declining membership, the abandoned Community Council

Why TensorFlow Lite Has Been Running Slower On Recent Linux Kernels

The Linux 5.0 to 5.9 kernel benchmarking posted this week showed TensorFlow Lite running slower since the Linux 5.5 kernel... On top of looking at the new Linux 5.9 regressions , I also spent some time bisecting and figuring out what happened for TensorFlow Lite last year that has at least for the system under test caused it to run slower for all the kernel releases this year as shown in the aforelinked article.

So with the speedy AMD EPYC box and knowing the regression happened between Linux


GNOME's New Power-Profiles-Daemon Sees "v0.1" Release

As work that should come together during the GNOME 3.40 cycle, the power-profiles-daemon project has just tagged its "v0.1" inaugural release as part of the work on better power management handling / power profiles easily configurable from the GNOME desktop.

A few days ago I reported on GNOME Power-Profiles-Daemon for better system/laptop power controls by allowing power-saving presets of "balanced", "power-saver", and "performance" from the GNOME Control Center

WSL2 Adding Support For Mounting Physical Disks, EXT4 Access And More From Windows

The latest functionality Microsoft is adding to their Windows Subsystem for Linux 2 (WSL2) is support for attaching and mounting physical disks within WSL2.

The newest Windows Insiders Preview Build adds support for the wsl --mount option for attaching and mounting physical disks attached to the system. This is intended for accessing data on Linux file-systems that are not natively supported by Windows, like EXT4 and many others.

Particularly for those using multi-boot setups or performing Linux backups to EXT4 or other non-

Mesa 20.3 Picks Up New Capabilities To Help With Display Presentation Jitter, Stuttering

Being merged today to Mesa 20.3-devel were some improvements aiming to help with display presentation jitter and hopefully avoid stuttering in the frame-rate.

Adam Jackson of Red Hat has been working on supporting GLX_EXT_swap_control/GLX_EXT_swap_control_tear for Mesa's GLX implementation and on the Vulkan side support for VK_PRESENT_MODE_FIFO_RELAXED_KHR.

GLX_EXT_swap_control_tear allows a negative value for glXSwapIntervalEXT to allow

Kernel Bisecting Has Never Been Faster Than With AMD EPYC + AMD Threadripper

While Zen 3 is just around the corner , current-generation Ryzen Threadripper and EPYC processors continue to impress particularly for build boxes and tasks like bisecting the Linux kernel's massive codebase.

Traditionally bisecting every performance regression I come across at Phoronix whether it be in compilers, the Linux kernel, or other code-bases has been prohibitively time consuming (and in turn cooling/power expensive) especially when operating on thin margins as is from the depressed state of the web ad industry, etc, but the incredible speed of

X-Plane 11.50 Officially Released With Its Vulkan Renderer

X-Plane has long been Linux-friendly and one of the most realistic flight simulators available while today it's taking a big step forward with its 11.50 release and the much anticipated introduction of its new rendering engine with Vulkan support.

After being in public beta for months, X-Plane 11.50 is now official as the latest stable version of this high quality flight simulator.

Making use of Vulkan over its aging OpenGL renderer can mean much better performance. See our X-

Raspberry Pi 4 VC4 Support Coming With Linux 5.10

The big set of patches for Raspberry Pi 4 / BCM2711 display support with the VC4 DRM driver will finally be merged next month for the Linux 5.10 cycle.

While the Raspberry Pi 4 has been available for over one year already, the BCM2711 display pipeline code has been a work-in-progress and going through multiple rounds of patch review for its 80 patches on top of the existing Broadcom VC4 open-source kernel driver code.

Intel Working On VA-API AV1 Acceleration For FFmpeg

With Intel Xe LP / Tigerlake adding AV1 accelerated video decode , the Intel open-source developers are working to expose their AV1 hardware acceleration through the Video Acceleration API (VA-API) for usage by the likes of FFmpeg and other multimedia software.

FFmpeg as one of the most notable multimedia libraries is now seeing VA-API AV1 support plumbed as a result of Intel engineers for supporting the AV1 acceleration once Tigerlake notebooks hit the market.

Sent out on Wednesday is the AV1 hardware acceleration decoder and

GRVK 0.2 Continues Advancing This AMD Mantle To Vulkan Translation Layer

While there aren't too many Windows games out there still popular and supporting AMD's Mantle graphics API that was the precursor to Vulkan, open-source developer Clément Guérin continues work on his "GRVK" initiative for mapping Mantle on top of Vulkan as a learning exercise and for allowing those still relevant Mantle-supported games to in turn run on Vulkan.

It was just last month that brought the inaugural GRVK release for this open-source project when it got a Mantle triangle rendered and begins
