It turns out Fedora 29's Mesa 19.0 packages have recently been shipping in a "debug" mode since they switched to using the Meson build system and that has been leading to slower performance.

SUSE developer Thomas Zimmermann has posted his work on "FBDEVDRM" as a new Direct Rendering Manager driver for exposing the DRM interfaces on top of legacy "FBDEV" frame-buffer drivers. For old frame-buffer drivers not ported to modern DRM/KMS interfaces, this could open up some interesting possibilities and at least allow these vintage display drivers to work with the likes of Plymouth and other programs only supporting the DRM interfaces.

For nearly six years there has been a bug report about high CPU load when using the NVIDIA proprietary driver causing high CPU load when running the KDE desktop and making use of double buffering. This issue has been finally resolved.

Google developer Matthew Garrett recently took over work on the long-standing "LOCKDOWN" kernel patches with a goal of preventing the running kernel image from being modified and strengthen the boundary between UID 0 and the kernel. These patches, which have been around for years and shipped by some Linux distributions, didn't make it into the recent Linux 5.1 merge window but now a pull request has been issued in trying to ship it with Linux 5.2.

Earlier this month was the feature proposal for Fedora 31 to finally upgrade to Mono 5, which has been out for nearly two years for this open-source .NET environment.

While Intel's Iris Gallium3D driver is not enabled by default and considered still experimental in its support of Broadwell graphics and newer, in all of our tests thus far it's been working out very well and haven't encountered any hangs so far in our tested OpenGL workloads. But with no OpenGL driver being immune from potential GPU hangs, a patch series is pending to improve the GPU recovery heuristics.

Valve Software has been backing work on Fossilize as an open-source project providing a serialization format for persistent Vulkan object types.

Since the short-lived Ubuntu 17.10 GNOME + Wayland experience, the Ubuntu desktop has still been using the trusted X.Org Server session by default. While Ubuntu 19.04 will soon be shipping and the Ubuntu 19.10 development cycle then getting underway, don't look for any Wayland-by-default change to be around the corner.

It's been just over one year since the previous release of Redox OS while today this Rust-written operating system has finally been succeeded by Redox OS 0.5.

Last month brought the release of PyPy 7.0 as the JIT-ed performance-optimized Python implementation. PyPy 7.0 brought alpha Python 3.6 support, an updated CFFI module, and other enhancements. Out now is PyPy 7.1 as its successor.

Linus Torvalds has announced the second weekly release candidate for Linux 5.1.

A few days ago I posted some Chrome vs. Firefox benchmarks using the latest Linux builds. Some readers suggested Firefox could be more competitive if forcing WebRender usage and/or moving to the latest nightly builds, so here are some complementary data sets looking at such combinations.

For fans of GNU's Nano text editor, version 4.0 was released this Sunday where overlong lines are no longer automatically hard-wrapped, smooth scrolling has been enabled by default, and other improvements made.

During this week's Game Developers Conference was the usual Khronos Dev Day where Vulkan, WebGL, glTF, and OpenXR took center stage. During the Vulkan State of the Union some details on their future endeavors were covered.

With existing Windows APIs being a nuisance, under NDA'ed documentation, and other problems, WireGuard developers have taken to developing a "good" TUN driver for Windows. This lets user-space programs serve as virtual network adapters to read/write directly into the network stack.

The OpenChrome driver is still inching towards the mainline kernel more than one decade after VIA x86 graphics were last somewhat common. The newest achievement for the OpenChrome DRM driver is the merging of the new TTM memory allocator code.

The MOTU 8Pre is a Firewire-connected device for digital audio workstations to be able to connect eight microphone inputs. The hardware itself is more than one decade old and in fact the manufacturer already discontinued the product, but with Linux 5.2 the kernel will be supporting this device.

Released for GDC/GTC week was Nsight Graphics 2019.2, the proprietary cross-platform, closed-source utility tool for debugging, profiling, and analyzing Direct3D, OpenGL, and other GPU-accelerated APIs.

For those with a PRIME style notebook or just making use of dual/multiple graphics processors in your system, Primus-VK allows for using a secondary/dedicated GPU for rendering while driving the display from the alternative (often integrated graphics) GPU. Primus-VK is implemented as a Vulkan layer as a clean approach for dealing with multiple GPUs in a Vulkan world.

A few weeks back I wrote about Xilinx looking at contributing their Alveo FPGA accelerator drivers to the mainline Linux kernel. They are continuing to work on that goal and pushed out their latest kernel driver patches this week for these Alveo PCIe accelerator cards.

While the Linux 5.0 kernel brought initial support for the long-awaited open-source FreeSync implementation, the Linux 5.2 kernel coming out this summer will likely have additional improvements.
