Wayland 1.20 is out today as the latest version of the reference Wayland library/support code and core protocol...

At the end of October came the pleasant surprise of the introduction of the Raspberry Pi Zero 2 W. This drop-in replacement to the original Raspberry Pi Zero features a more powerful 1.0GHz quad-core Cortex-A53 compared to the miniscule 1GHz single-core design of the original Pi Zero while boasting 512MB of LPDDR2 RAM. Here are some initial benchmarks of the Raspberry Pi Zero 2 W for those curious about its performance.

In addition to the LLVM SPIR-V back-end appearing ready for merging, also working through the final steps for being mainlined in the LLVM compiler stack is also Facebook's BOLT project for optimizing the performance of binaries...

Taking place in San Francisco from Monday through yesterday evening was the RISC-V Summit for discussions around this dominant open-source processor ISA. For those that were did not make it to the event, many of the slide decks are available...

It is not too often getting to talk about performance optimizations for Mesa's Virgl code that along with in conjunction with related "Virgil" components allows for hardware-accelerated 3D/OpenGL running within virtual machines. Hitting Mesa 22.0 this week though is some Virgl code improvements for allowing lower memory use within virtual machines...

Intel's oneDNN Deep Neural Network Library that is part of their oneAPI toolkit is out with version 2.5 and brings RISC-V CPU support among other updates...

Engineers from Intel and Arm in cooperation with The Khronos Group feel ready now to begin landing their SPIR-V back-end within the upstream LLVM source tree! This SPIR-V back-end for LLVM would ultimately allow LLVM front-ends for different languages to more easily target this industry-standard shader representation so that it could be ingested by Vulkan / OpenCL drivers...

While Ubuntu switched from LZ4 to Zstd for compressing its initramfs, they now are finding they were too aggressive in defaulting to Zstd with the highest compression level of 19. Due to speed and memory consumption concerns, they are looking at lowering their Zstd compression level...

AMD's Linux engineers continue preparing for next-gen EPYC server processors based on Zen 4 and supporting DDR5 memory...

The Cloud-Hypervisor open-source project started by Intel a few years ago as a Rust-written VMM focused on cloud workloads is now going to be hosted by the Linux Foundation...

Microsoft has introduced "Microsoft-Performance-Tools for Linux-Android" as a collection of open-source tools for analyzing system performance on Linux and Android...

When it comes to the state of packaged web browsers for Debian GNU/Linux, unfortunately it leaves a lot to be desired at the moment and for those wanting to be secure and up-to-date it can mean resorting to proprietary or un-packaged browser builds...

Mesa's Radeon Vulkan driver "RADV" is implementing emulated support for ETC2 texture compression to use with newer AMD GPUs to improve compatibility with Google's Android operating system...

Google is looking to upstream their Linux kernel driver for Open Profile for DICE, a secret derivation protocol used currently by some Android devices...

One of many exciting features/changes with upcoming Intel Xeon Scalable "Sapphire Rapids" processors is the introduction of Advanced Matrix Extensions (AMX). While initial AMX support is premiering with Linux 5.16 due out in stable form as the start of the new year, it currently doesn't allow for KVM virtualized guests to make use of the new capabilities...

While FreeBSD 13 is the current stable version of this leading open-source BSD operating system, FreeBSD 12.3 shipped today for their N-1 series...

While all of the software components are out there now for being able to run NVIDIA's proprietary driver stack with modern (GBM-based) Wayland compositors by default, including XWayland support, Fedora Workstation currently defaults to using an X.Org based session with the green binary blob. However, for Fedora 36 next spring they are planning on using the Wayland-based desktop here too...

Back in September Intel originally posted Linux patches for "Software Defined Silicon" for being able to activate extra CPU features present in the processor's silicon but not exposed by default unless the cryptographically secure process with this SDSi driver was performed. Intel appears to be moving toward allowing licensable processor features that can be activated after the fact and today a new version of that SDSi Linux driver appeared...

AWS recently introduced Amazon Linux 2022 in preview form as the latest iteration of their Linux distribution now based on Fedora with various alterations to catering to their customers running it on EC2. Last week were benchmarks looking at Amazon Linux 2022 compared to Amazon Linux 2 and other distributions like CentOS and Ubuntu. In this article we are seeing how Amazon Linux 2022 can compete with Intel's own Clear Linux performance-optimized distribution.

Along with XWayland touchpad gestures, another shiny feature was merged this week into X.Org Server Git for XWayland: DRM leasing support!..
