Last week AMD sent out initial patches for enabling the "GFX 11.5" graphics IP under Linux for this presumed RDNA3 refresh that is likely for their next-gen Ryzen 8000 series APUs. Today AMD open-source Linux driver engineers sent out DCN 3.5 patches as an updated version of their Display Core Next IP...

Fedora Workstation has long maintained the QGnomePlatform and Adwaita-qt projects for applying a GNOME/GTK-like interface and styling to Qt applications in order to enhance the experience. However, to reduce the maintenance burden and the ongoing technical debt, Fedora Workstation 39 is planning to eliminate the custom Qt theming and just rely on Qt upstream...

Earlier this month when the AMD Inception CPU vulnerability was disclosed the initial mitigation was merged to Linux kernel right away for what there is referred to as the Speculative Return Stack Overflow (SRSO). Within a day of that code being published there were already efforts to clean it up and merged last week for Linux 6.5-rc7 was that AMD Inception code cleaning. This week a new set of 22 patches were published for further improving the AMD Inception/SRSO mitigation code...

Googler Rob Clark on Sunday sent out the set of MSM DRM patches prepped for the upcoming Linux 6.6 merge window.

Following the news last week of Firefox outperforming Chrome in SunSpider, a Phoronix reader pointed out Mercury that is an open-source web browser claiming to be the "fastest Firefox fork" and making use of Advanced Vector Extensions (AVX) and AES instructions along with compiler features like Link-Time Optimizations (LTO) and Profile-Guided Optimizations (PGO). The project advertises as being 8-20% faster than upstream Firefox. Curious I ran a couple benchmarks on my end of this Firefox fork.

GNOME's Sysprof is a wonderful system-wide profiling tool for helping developers analyze bottlenecks and debug other challenging issues. This system profiler has covered both kernel and user-space but to date has not provided any insight around the CPU scheduler behavior and thus developers have had to resort to other tooling there. But for the GNOME 45 release, Sysprof has integrated CPU scheduler details...

One nugget of information in the LibreOffice 7.6 release announcement for those who missed it and deserves calling out specifically... Succeeding LibreOffice 7.6 will not be v7.7 or v8.0 but rather v24.2...

Intel is well regarded for their vast open-source contributions from being a major contributor to the Linux kernel and other areas like Mesa, GCC/glibc, and other key open-source projects to various niche projects like ConnMan and other smaller software projects. Debuting a few months ago as one of the newest open-source Intel projects catching us by surprise was Intel One Mono as a font designed for developers. Today brings a new version of that font...

New (Windows) tools have been released that break the NVIDIA BIOS Signature Lock, the "security" functionality in use since the GeForce GTX 900 days around signed firmware/BIOS handling. This authentication mechanism is what in turn has led to the GeForce GTX 700 series still being the best supported series by the open-source Nouveau driver while the GTX 900 series and later have been crippled to their low boot clock speeds due to PMU/re-clocking restrictions. While Nouveau developers have been working on the GPU System Processor (GSP) approach for RTX 20 "Turing" GPUs and newer to workaround this limitation as NVIDIA's blessed path forward, the NVIDIA BIOS Signature Lock has now been broken by Windows modders...

For those that have been eyeing an AMD Ryzen 7 7040 "Phoenix" series laptop for Linux use, over the coming weeks ahead there will be benchmarks and a review on the Lenovo ThinkPad P14s Gen4 with AMD Ryzen 7 PRO 7840U laptop. With this 8-core / 16-thread Zen 4 mobile processor clocking up to 5.1GHz, 64GB of LPDDR5x-6400 memory, 1TB NVMe SSD, and 2.8K OLED display it should be a real treat if the Linux support is all in good shape...

Earlier this month the AMD Inception vulnerability was disclosed and quickly mitigated within the mainline Linux kernel and back-ported to the stable kernels. In the rush to get the code merged and the mitigation being under embargo until the disclosure date, some bugs and clean-ups with the mitigation code were discovered. That revised code was now submitted today for merging ahead of the Linux 6.5-rc7 kernel release this weekend...

Over the past month I've been delivering a number of Linux laptop tests with the AMD Ryzen 7 7840U for that Zen 4 "Phoenix" SoC within an Acer Swift Edge 16. One of the requests that has come up with my ongoing testing has been how well the default Microsoft Windows 11 installation compares to loading up Linux on this 8-core AMD Zen 4 laptop. Well, in this article is a look at the Linux performance compared to Windows 11, including when making use of the Linux 6.5 development kernel where AMD P-State is now the default and also for seeing what workloads are impacted by the recent AMD Inception vulnerability.

Linux 6.4 or newer paired with the latest cryptsetup development code has landed support for the OPAL specification for self-encrypting drives...

There are additional optimizations on the horizon for the RadeonSI Gallium3D driver for benefiting OpenGL on Linux workstations...

While back in November was when AWS originally announced new EC2 instances powered by 4th Gen AMD EPYC "Genoa" processors, only this week did they bring their M7a general purpose instances to a general availability state where anyone can access them. Being very impressed with 4th Gen EPYC bare metal as well as with Azure's HPC cloud, I fired up some benchmarks of the new Genoa-powered EC2 M7a instance compared to the new M7i instances powered by Intel Xeon Scalable "Sapphire Rapids" as well as showing how the competition is to Amazon's in-house Graviton ARM-based server processors.
