X.Org Foundation Bows Out For Google Summer of Code 2021

Over the years Google Summer of Code (GSoC) has resulted in some really great projects in the X.Org ecosystem from work in the early days on the open-source Radeon graphics driver stack to VKMS more recently to many other improvements especially as it pertains to open-source graphics drivers / Mesa. But for Google Summer of Code 2021 at least, the organization will not be participating…

KDE Plasma 5.22 Adds Adaptive Opacity + Will Avoid Useless Rendering When Screen Is Off

KDE developers have been off to a busy March so far with working on adaptive panel opacity support for Plasma 5.22. Another pleasant improvement with that next Plasma release is to avoid rendering work when the screen is off…

Linux Developers Continue Discussing "SLS" Mitigation For The Kernel

Disclosed by Arm last summer was the Straight Line Speculation (SLS) vulnerability and they were quick to introduce new safeguards against SLS in the GCC and LLVM compilers. The compiler-based mitigations to straight-line speculation involves adding speculation barrier sequences around the vulnerable instructions to prevent speculatively executing instructions around changes in control flow. While compiler developers were quick to add the options, so far the Linux kernel developers are in disagreement still over its importance and the proposed patches that would flip on this option when compiling the ARM Linux kernel…

Linux 5.12-rc2 Released Early – A Rare Friday Kernel Due To That Nasty Corruption Issue

While Linus Torvalds long has released his new kernel releases — both release candidates and the inaugural stable releases — every Sunday, there are the occasional exceptions like this week with Linux 5.12-rc2 being issued on Friday night. The Linux 5.12-rc2 release has come early due to that nasty file-system corruption issue stemming from botched swapfile handling…

Radeon RX 6800 Series Seeing Some Small Gains With Linux 5.12

When it comes to the AMDGPU kernel driver changes in Linux 5.12 for modern open-source AMD Radeon graphics, most notable is RDNA2 OverDrive overclocking support now being available as well as AMDGPU FreeSync over HDMI (pre-HDMI 2.1). But from initial testing the new in-development kernel is showing mostly subtle performance improvements for the Radeon RX 6800 series over Linux 5.11.

Intel Tiger Lake Xe Graphics On Linux 5.12 Git, Mesa 21.1-devel

Recently I wrapped up some tests looking at the Dell XPS Linux laptop with Core i7 1165G7 “Tiger Lake” processor when looking at the Linux kernel performance of 5.10 vs. 5.11 vs. 5.12 as well as the impact if upgrading to the Linux 5.12 kernel…

Wine's Project Leader Has Given A Blessing To The Wayland Effort

Published last month was an updated but still experimental version of the native Wayland support for Wine after that code was originally published last year. One of the lingering questions has been around the prospects of mainlining this Wayland driver in Wine while last week the longtime Wine project leader, Alexandre Julliard, provided some clarity on the matter…

Even In 2021, Intel Squeezes Some Very Nice Performance Gains Out Of Their OpenGL Driver

While it’s 2021 and many modern Linux gaming and other workloads are focusing on the Vulkan API, Intel isn’t letting up in their aggressive optimizations to their open-source “Iris” OpenGL Gallium3D driver for Linux systems. With the latest Mesa 21.1 code today there is a set of patches providing up to 17% better performance in some games while other OpenGL software is generally a few percent faster at least. In some micro-benchmarks it can be more than 50% faster…
