With the Ryzen 6000 "Rembrandt" mobile processors most exciting about these Zen 3+ SoCs has been the energy efficiency improvements and moving from Vega to RDNA2 graphics as with the Radeon 680M found on the Ryzen 7 PRO 6850U that I have been running many Linux benchmarks on over the past several weeks. For those wondering if it pays off moving to a newer Linux kernel or Mesa version with Radeon 680M integrated graphics, here are some reference benchmarks I recently conducted...

Sent out this morning is a Linux kernel "fix" that now enabled STIBP when using the IBPB mode for Retbleed mitigations on AMD processors. In other words, more protections needed for this enhanced mode of Retbleed mitigation...

Last week was the main set of RISC-V updates for Linux 6.0 that included improving Svpbmt support, a more robust default kernel configuration, and other improvements. A secondary set of RISC-V CPU architecture updates has now been merged for Linux 6.0...

It's been another busy summer week for KDE developers with many new features and fixes landing within this open-source desktop stack...

A number of changes were merged into Linux 6.0 for benefiting virtualization when making use of VirtIO...

Intel has contributed support for their oneVPL open-source video processing library to the upstream FFmpeg project for that widely-used, cross-platform multimedia library...

While much of the Intel Arc Graphics "Alchemist" (DG2) support appears squared away for Linux 6.0 besides the support still being hidden behind the flag requiring i915.force_probe= to actually enable the experimental support, there still are various DG2 discrete GPU features being tackled by the open-source Intel kernel graphics drivers. One of those "extras" still working its way to the kernel is HWMON subsystem integration to be able to expose power / voltage / energy reporting...

Released in June was the Radeon PRO Software for Enterprise 21.Q2 to deliver AMD's enterprise-vetted graphics driver stack to Windows users. Meanwhile recently debuting is the long-awaited adjacent Radeon Pro Software for Enterprise for Linux driver update...

The colorful fishy codenames are not over for AMD's Linux driver crew! While on the GPU side they have moved to IP block-by-block enablement strategy for their future GPUs, over on the audio co-processor side AMD posted a series of patches today under the "Pink Sardine" codename...

With Mesa 22.2 bringing many new features, you may be curious about how the performance of this next Mesa3D release is looking. For your viewing pleasure today are benchmarks of Mesa 22.2 back from the day it was branched against that of the stock Mesa 22.0 on Ubuntu 22.04 if you have been wondering whether it's worthwhile upgrading... Benchmarks for this article from the current-generation Radeon RX 6700 XT and RX 6800 XT graphics cards.

The Flash Friendly File-System (F2FS) continues showing its a formidable file-system option for flash memory devices, especially SSDs and mobile hardware. With Linux 6.0 there are yet more improvements for this file-system driver...

Valve contractor Mike Blumenkrantz who works on Zink for OpenGL implemented atop Vulkan has managed some more performance optimizations with the upcoming Mesa 22.2 quarterly feature release...

While Intel's performance-optimized Clear Linux rolling-release distribution is known for its aggressive performance optimizations, their kernel build had been going with the default "-O2" optimization but last week did switch over to rolling their kernel with -O3...

While support for the loongArch Chinese CPU architecture was merged in Linux 5.19, it wasn't actually enough to yield a booting system due to some driver code not yet being finished and ready for merging in time. LoongArch was allowed to merge that preliminary code in v5.19 so the Glibc support could land and now for Linux 6.0 more of the CPU port is ready to hit the kernel...

When it comes to the Apple M1 and M2 support on Linux, one of the biggest obstacles to suitable daily use for end-users is the current lack of GPU acceleration. Reverse engineering has been happening for the Apple Silicon graphics processor, early experiments being carried out under macOS and Asahi's m1n1 environment, and the next step will be to start writing a Direct Rendering Manager (DRM) kernel driver. To some surprise, the feasibility of writing this DRM kernel GPU driver in the Rust programming language is being explored...

A number of new Linux kernel stable releases are out this week with new mitigations around the latest batch of published CPU security vulnerabilities. Linux 5.19.1, 5.18.17, 5.15.60, 5.10.136, 5.4.210, and 4.19.255 are the new releases out today...

While all of the key Zen 4 CPU functionality appears in place for the mainline Linux kernel, AMD engineers continue working to enable other new Zen 4 features for use under Linux. The newest patches out of AMD this morning are for LbrExtV2...

Following a one week delay due to a last minute blocker bug being discovered, Canonical today has shipped Ubuntu 22.04.1 LTS as the first point release to this current long-term support series...

Following GCC 12 introducing LoongArch support earlier this year, Linux 5.19 adding the initial LoongArch port, and Glibc 2.36 adding LoongArch, LibreOffice is now the latest high-profile open-source project adding support for this Chinese processor ISA that started out derived from MIPS64...

GNOME's Shell and Mutter components have released their beta versions for this GNOME 43 milestone. Particularly on the Mutter side are some very exciting changes from improvements to direct scan-out, high resolution scroll wheel support being completed and merged, various Wayland improvements, and more performance optimizations...
