Here is a look at how the performance of Intel's Clear Linux compares for the end of 2020 against the end of 2019 and 2018 on the same hardware platform for looking at the Intel performance optimizations made to this open-source Linux distribution. This was another year of Intel engineers making more headway on out-of-the-box Linux performance even though they have been less vocal about the project over the past year.

AMD is back on track publishing more Zen 3 compiler support patches for the LLVM compiler stack...

Adding to the growing list of Mesa 21.0 features is spare memory support for the Radeon "RADV" Vulkan driver...

While Linux 5.11-rc2 was tiny due to the holidays, with developers and testers returning to work the Linux 5.11-rc3 release that was just issued is much bigger...

Several months back you may recall that Linux 5.9 kernel regression we noted that in turn was bisected to code introduced by Linus Torvalds around page lock fairness. That was ultimately worked out in time with allowing a control over the page lock (un)fairness to address the regressed workloads while being fair enough to satisfy his original change. But now this week for Linux 5.11, Linus Torvalds has again altered the behavior. It then ended up causing a PostgreSQL database server performance regression but fortunately any impact should be very minimal and hopefully not appearing in any real-world situation...

With Linux 5.10 having shipped as the latest Long Term Support (LTS) release to be maintained for at least the next five years, a discussion has begun over dropping a number of old and obsolete CPU platform support currently found within the mainline kernel. For many of the architectures being considered for removal they haven't seen any new commits in years but as is the case once proposals are made for them to be removed there are often passionate users wanting the support to be kept...

BeOS-inspired Haiku OS can now run with Mesa 21.0 well using the latest development code...

With this week's R460 driver release also comes a number of security updates. Several security issues have been patched in both the NVIDIA Windows and Linux graphics driver components...

While Fedora has been well known for years in always shipping the very latest packages in its distribution as of release even if it means using the likes of a near-final GCC compiler pre-release, developers have decided to postpone the shipping of PHP 8.0 until the autumn with their Fedora 35 release...

As part of Intel's lengthy "Keem Bay" upstreaming for Linux as their latest-generation Movidius VPU offering, now that much of the core infrastructure bits are all mainlined, the latest focus has been on their Vision Processing Unit enablement...

Stemming from the renewed attention this week of Haswell GT1 graphics being broken for the past half-year under Linux with the latest versions of the kernel, a revised patch was sent out to restore that graphics support for low-end Haswell Celeron/Pentium processors. As part of that, a new option is being introduced to allow disabling security mitigations of the Intel graphics driver...

This week AMD engineers published their initial code for the AMDGPU/AMDKFD Linux kernel driver for providing a Heterogeneous Memory Management based Shared Virtual Memory (SVM) memory manager that ultimately will be used by their ROCm compute stack...

Alibaba developers released an updated version of their "blazing fast" lightweight deep learning framework MNN, or the Mobile Neural Network...

With last week's release of dav1d 0.8 for CPU-based AV1 video decoding we provided a number of x86_64 benchmarks while questions were raised around the ARM64 and POWER9 performance. Here are such benchmarks for those wondering about the AV1 video decoding speed on those architectures...

KDE's KWin window manager / compositor has seen a "near total rewrite" of its compositing code that should sharply improve the desktop...

Building off yesterday's Wine 6.0-RC6 release is an updated Wine-Staging build...

With Linux 5.11 the Intel Linux graphics driver is bringing async page-flipping for Gen9/Skylake and newer. However, patches pending for a future release (potentially 5.12) would extend that performance benefiting feature now all the way back to the Ironlake days...
