Latest Linux Hardware Reviews, Open-Source News & Benchmarks

The past few months there has been a change proposal discussed around adding "-fno-omit-frame-pointer" to the default compilation flags for packages being built for Fedora Linux. Adding this option would improve the profiling/debug-ability of the packages but with possible performance implications. The Fedora Engineering and Steering Committee (FESCo) has now rejected this contentious change proposal.

While NVIDIA users have been enjoying hardware ray-tracing with the Blender 3D modelling software for years with the OptiX back-end and RTX GPUs, the ray-tracing support for AMD Radeon and Intel Arc Graphics is still coming together for this industry-standard, open-source 3D modelling software.

With November now in the books, here is a look back at the most popular original open-source/Linux content on Phoronix from the 245 original articles written by your's truly over the past month. It was an extremely exciting month given the launch of the AMD EPYC 9004 "Genoa" processors with up to 96 cores per socket, AVX-512, and with all of the improvements meant outright insane generational improvement and currently slaughtering the competition. The Linux 6.1 kernel nearing the limelight, early development work on Linux 6.2, and the continued embracing of the Rust programming language by the open-source ecosystem all made for an interesting November.

NixOS as the Linux distribution built atop the purely-functional and declarative Nix package manager is out with a new release to kickoff December.

At the start of the year SDL attempted to prefer Wayland over X.Org/X11 thanks to the maturing Wayland support for this widely-used software/hardware abstraction layer by numerous cross-platform games. But that change was later reverted over ecosystem challenges around Wayland. Now as we approach the end of the year, SDL is again trying to prefer Wayland over X11.

Beyond Intel's well regarded open-source software work deep down the stack on everything from ensuring timely new hardware support to optimizing the Linux kernel with various performance optimizations and investing heavily in the upstream GNU and LLVM toolchains (and much more!), they also make terrific software ecosystem advancements higher up the stack. One of their most promising areas of open-source software work in recent years has been around oneAPI. Next week Intel will be hosting a virtual oneAPI DevSummit for AI and HPC where they will be showing off their latest software advancements.

The much anticipated Godot 4.0 open-source game engine continues inching closer to release. When that release is finally out, Godot 4.0.x point releases will likely be coming in quick and some plans for Godot 4.1 are already being discussed.

Wayland Protocols 1.31 has been released and this collection of protocols is now headlined by the addition of fractional scaling support!

Talked about for over two years now has been a "readfile" system call to efficiently read small files. This should be a win when dealing with small files like those exposed via sysfs while it's taken time to come together and stalled out several times. This week Greg Kroah-Hartman has updated the readfile patches leading to hope that this new syscall might finally be on a path for mainlining.

While these days the Intel-owned Habana Labs Linux software stack is a shining example of an open-source AI accelerator solution with mainline kernel driver support and also helping bring together the new compute accelerator subsystem, it wasn't always so blessed. Initially there was the closed-source user-space bits that fortunately last year was opened up with SynapseAI Core.

While for years Intel has been very well regarded -- and rightfully so -- for their open-source Linux hardware support, occasionally there are exceptions. One such exception currently is Intel's IPU6 drivers for their MIPI cameras found on many newer Alder lake laptops and presumably upcoming Raptor Lake laptops too. The IPU6 drivers remain outside of the Linux kernel and will still likely be that way for sometime.

With the Linux 6.1-rc7 kernel set to be released later today, it will become easier making use of the AMD P-State driver for that enhanced CPU frequency scaling driver intended for Zen 2 and newer EPYC/Ryzen platforms that make use of ACPI CPPC.
