The Linux 6.5 kernel is expected to be released as stable this weekend barring any last minute issues from being raised. One of the notable changes with this new kernel version is Linux now defaulting to the AMD P-State "EPP" active driver configuration for modern Ryzen systems rather than the long-used generic ACPI CPUFreq driver default. In some cases this can mean better performance but particularly should yield a nice improvement to the power efficiency of Ryzen Zen 2 and newer platforms, especially laptops and other portable Linux systems like the Steam Deck and ROG Ally. I am working on some fresh AMD Ryzen Linux laptop comparison benchmarks but for this article is a look at Linux 6.5 on the desktop side with the AMD Ryzen 9 7950X.

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...

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...

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...
