Linux Developers Discuss Deprecating & Removing ReiserFS
Besides no discussion in years over possibly upstreaming Reiser4 nor have any been brought up about eventually trying to mainline Reiser5, it looks like the original and feature-rich for its original time ReiserFS file-system could be on its way out of the Linux kernel in 2022.

GNOME Dynamic Triple Buffering Can 2x The Desktop Performance For Intel Graphics, Raspberry Pi
For a while now Daniel Van Vugt of Canonical has been working on GNOME triple buffering support that would be dynamically enabled when the GPU rendering performance is falling behind. It's looking like that dynamic triple buffering may be close to mainlining and is leading big speed-ups for Intel graphics and the Raspberry Pi Broadcom graphics too while the other drivers ultimately should benefit too if falling behind in their desktop rendering performance.

Rust For The Linux Kernel Sent Out For Review A Fourth Time
Miguel Ojeda just sent out the fourth revision of the Rust programming language support for use within the Linux kernel. This optional Rust programming support for Linux kernel drivers and the likes continues maturing and this year will hopefully see mainline status.

AMD Quietly Working On New Linux GPU Driver Support Block By Block
AMD's Linux graphics driver engineers have been working on the driver support for new graphics processors and now the patches are at the earliest stages of publishing. However, due to driver handling changes, it's sharply different this time around where in the past they volleyed a big set of patches under some colorful fishy codename in an effort to conceal their hardware enablement work.

X.Org vs. (X)Wayland Gaming Performance For NVIDIA GeForce & AMD Radeon On Ubuntu 22.04
Earlier this month I posted some Ubuntu 22.04 Linux gaming benchmarks with X.Org vs. (X)Wayland performance for NVIDIA GeForce graphics now that the NVIDIA 510 driver has the GBM support in good shape. NVIDIA's (X)Wayland gaming performance is largely in good shape now while for those wondering how it compares to AMD Radeon on Ubuntu 22.04 daily, here are some benchmarks.

Raspberry Pi OS 32-bit vs. 64-bit Performance
Last week marked the long awaited release of a 64-bit spin of Raspberry Pi OS. The Raspberry Pi Foundation has now made available a 64-bit build of their default Linux OS build derived from Debian for all recent Raspberry Pi hardware supporting AArch64. For those curious, here are some benchmarks looking at the performance improvement by switching from Raspberry Pi OS 32-bit to 64-bit.

Further Investigating The Raspberry Pi 32-bit vs. 64-bit Performance
Finally released earlier this month was the first official 64-bit build of Raspberry Pi OS, the official Debian-based operating system of the low-cost Raspberry Pi single board computers. Following that I posted some Raspberry Pi 32-bit vs. 64-bit benchmarks. Given that generated a fair amount of interest and also some open questions, here is round two of looking at the Raspberry Pi 32-bit vs. 64-bit performance including its impact on memory usage and thermals.

NVIDIA Linux Gaming Performance For Wayland vs. X.Org On Ubuntu 22.04
With NVIDIA's newly-introduced 510 Linux driver series paired with the latest XWayland and a modern Wayland compositor like the newest GNOME/Mutter packages, the NVIDIA (X)Wayland experience is in great shape and delivering comparable performance to a traditional X.Org session. The NVIDIA Wayland support with GBM usage has stabilized and appears to be in good shape for the upcoming Ubuntu 22.04 LTS release. Here are some benchmarks of the NVIDIA 510 driver on the current state of Ubuntu 22.04 LTS.

Linux Now Faster Than Windows 11 For Intel Core i9 12900K With Latest Kernel
Back in November when Intel's 12th Gen Core "Alder Lake" processors first launched I ran benchmarks across operating systems and found Windows 11 delivering better performance than Linux with the Core i9 12900K flagship processor. Fortunately, thanks to kernel improvements since Linux 5.16, that is largely no longer the case. Here is a fresh look at the i9-12900K performance under Ubuntu 22.04 daily with Linux 5.16 and 5.17-rc3 kernels tested as well and Clear Linux for Intel's very own reference Linux platform.

For Linux Enthusiasts Especially, The Steam Deck Is An Incredible & Fun Device
Over the past nearly 18 years of running Phoronix, I have come across many interesting Linux-based products from Linux embedded in motherboards for instant-on use to the BlackDog USB port pen drive Linux servers to solar-powered super-computers in trash cans. The most fun and promising Linux-powered gaming device for the masses though is launching today: Valve's Steam Deck. I've been fortunate to be testing out this Arch Linux derived handheld game console the past month and it has been working out very well -- both as a portable Steam gaming device but making it even more compelling from the Linux enthusiast angle is its "developer mode" that effectively turns it into a general Linux handheld and also being free to load your own Linux distribution of choice.

Squeezing More Performance Out Of An Intel Celeron "Alder Lake" CPU With A Faster Linux OS
Recently I tested the Intel Celeron G6900 Alder Lake processor as a $40~60 CPU and the lowest-end SKU as part of the latest-generation Intel desktop CPU line-up. Those tests were carried out on Ubuntu Linux (as usual) for that dual-core processor and was an interesting little processor for the price and for the lack of any AMD Zen 3 competition currently at that low price point. If needing to make daily use of such an Intel Celeron system, switching out your Linux distribution can help. In this article are benchmarks of the Celeron G6900 across Arch-based Manjaro, Intel's Clear Linux, Fedora Workstation 35, Ubuntu 22.04 daily, and openSUSE Tumbleweed.

Benchmarking Amazon EC2's New C6a Instances Powered By 3rd Gen EPYC
Last year Amazon launched the EC2 M6a instances powered by AMD EPYC 7003 series while this week they have expanded their range of AMD Zen 3 offerings by launching the EC2 C6a series. The EC2 C6a instances are designed for compute-intensive workloads (hence the "C" series) and AWS is promoting it as offering up to 15% improvement in price-performance over prior-generation C5a instances and up to 10% lower cost than comparable x86-based EC2 instances. I've run some benchmarks of the new EC2 C6a instances looking at how they perform over the prior 2nd Gen EPYC C5a based instances, against the Intel Ice Lake competition over in the M6i stack, and also how the C6a competes with Amazon's own Graviton2-based C6g type.

OnLogic ML100G-41 - A Great AMD Ryzen Powered SFF Industrial-Grade Computer
When it comes to small form factor (SFF) industrial PCs and IoT computers, it's been an area where Intel has traditionally dominated and served quite well. But now with the continued success of AMD's Ryzen processors, we are beginning to see more AMD-powered industrial computer solutions become available such as the recent OnLogic ML100 series with AMD SoC options. I've been testing out the OnLogic ML100G-41 powered by a Ryzen 7 4800U SoC for many weeks now and this fanless, industrial-grade computer has been running very well for a diverse variety of workloads.

Benchmarking Google's New "C2D" Compute-Optimized AMD Zen 3 Instances - N2D vs. C2 vs. C2D Performance
Yesterday Google Cloud launched their C2D instance type as their newest compute-optimized instances powered by AMD EPYC 7003 series processors. here are some quick benchmarks looking at the C2D performance against the existing Intel Xeon powered C2 instance type and the former EPYC 7002 based N2D instance type.

An Early Look At GCC 12 Compiler Performance On The Core i9 12900K
With GCC 12 now onto stage four meaning that the major feature work is over, I've slowly begun running more tests on the GCC 12 compiler that is due for its stable introduction around April. First up is a look at the Core i9 12900K "Alder Lake" performance on GCC 12 in its near-final form compared to GCC 11.2 as the current stable release from last year.
