Given the significant interest from Phoronix readers about how well Apple M2 performs on Linux, especially after it was noted Linus Torvalds using an Apple MacBook Air M2, here are the first of many benchmark articles to come looking at how well Apple's M2 performs under Linux against Intel/AMD x86_64 competition. The new Apple MacBook Air with M2 was benchmarked for this article against the AMD Ryzen 7 PRO 6850U "Rembrandt" Zen 3+, Intel Core i7 1280P "Alder Lake P", an AMD Ryzen 9 5900HX "Cezanne H", and also for reference an Apple Mac Mini M1 model. All of these laptops were tested under Arch Linux (x86_64) and the Arch-based Asahi Linux (M1/M2).

AMD Ryzen Threadripper PRO 5965WX Performance On Linux
8 August 09:00 AM EDT - Processors - 16 Comments

Earlier this year AMD announced the Ryzen Threadripper PRO 5000 WX series but initially was limited to Lenovo workstations. Earlier this summer it was then announced the Threadripper PRO 5000 WX series would be heading to more system integrators and then the DIY market. Well, finally, these Zen 3 Threadripper chips are heading out to the DYI market and today the review embargo lifts. AMD recently sent over a Ryzen Threadripper PRO 5965WX for my Linux testing at Phoronix and here is my initial review and performance benchmarks for this Zen 3 24-core / 48-thread HEDT chip.

8 August 05:31 AM EDT - Linux Kernel - Gaudi2 With Linux 6.0 - 2 Comments

The "char/misc" changes were merged a few days back for the Linux 6.0 kernel with this pull being the rather "random catch-all" area of the kernel for drivers not fitting within other subsystems. Most notable with the char/misc updates for Linux 6.0 is introducing support for Intel's Habana Labs Gaudi2.

8 August 12:00 AM EDT - AMD - Sabrina = Mendocino - 10 Comments

You may recall the Phoronix news earlier this year around an AMD "Sabrina" SoC appearing in Coreboot for open-source system firmware support. Over the past few months we've cited a number of AMD Sabrina hits in open-source code but outside of that haven't heard much else about "Sabrina" or seen it on AMD's roadmaps.

OpenSUSE Tumblewed Planning To Finally End ReiserFS Support
OpenSUSE Tumblewed Planning To Finally End ReiserFS Support
7 August 03:38 PM EDT - SUSE - Farewell ReiserFS - 18 Comments

SUSE had been one of the big supporters of ReiserFS two decades ago when it was using the ReiserFS file-system by default but that practice ended in 2006. While SUSE/openSUSE hasn't defaulted to ReiserFS for many years, it has remained an install-time option and retained support for mounting ReiserFS file-systems, but that practice is likely soon ending.

BUS1 Working On "r-linux" - A Rust Capability-Based Linux Runtime
BUS1 Working On "r-linux" - A Rust Capability-Based Linux Runtime
7 August 06:09 AM EDT - Linux Kernel - r-linux - 22 Comments

BUS1 started out as a Linux kernel IPC module following the failure of KDBUS and while there still are occasional commits to that out-of-tree BUS1 kernel module, the involved (Red Hat) developers have been primarily working on Dbus-Broker as the high performance, user-space D-Bus implementation that delivers greater speed and reliability over the reference D-Bus code. Now also popping up under the BUS1 umbrella is "r-linux" as a Rust-written, capability-based Linux runtime.

FBDEV Updates For Linux 6.0 Bring Fixes For The Atari Graphics Chipset Driver
7 August 05:09 AM EDT - Linux Kernel - Atari FBDEV - 4 Comments

Earlier this year a developer stepped up willing to maintain Linux's FBDEV subsystem for frame-buffer device drivers since it fell into an unmaintained state in 2016 but even prior to that had been on the decline in the era of more proper DRM/KMS drivers. Helge Deller continues that work overseeing the frame-buffer device "FBDEV" subsystem and this week sent in the new patches for Linux 6.0.

While OpenRISC has been around a decade longer than RISC-V and its original support in the Linux kernel dates back to the v3.1 days, on the hardware side OpenRISC hasn't enjoyed nearly as much success as RISC-V and its kernel support not advancing nearly as rapidly. Now with Linux 6.0, OpenRISC is finally exposing PCI bus support.

With Linux 6.0 having some big scheduler changes and tuning that should specifically benefit AMD Zen systems, I've been eager to see how some high core count EPYC servers will benefit from this next version of the Linux kernel. While just a few days into the Linux 6.0 merge window, here are some early benchmarks showing some of the areas where Linux 6.0 is allowing higher performance out of existing AMD EPYC 7003 series hardware.

There Is Another Debate Over An AI Accelerator Subsystem For Linux
4 August 06:55 AM EDT - Hardware - Linux Kernel Accelerator Subsystem - 11 Comments

With there recently being a number of new driver proposals for various AI-focused accelerators for the Linux kernel, currently they either go into "char/misc" as the random catch-all area of the kernel or within the Direct Rendering Manager (DRM) subsystem traditionally used for GPU drivers. There's been yet another discussion happening this week over introducing a formal "accelerator" subsystem in the kernel for the growing number of AI devices that may be seeking to provide open-source drivers.
