AMD Zen 5 Compiler Support Posted For GCC - Confirms New AVX Features & More
Making for a very exciting Saturday morning, AMD just posted their initial enablement patch for plumbing Zen 5 processor support "znver5" into the GNU Compiler Collection! With GCC 14 due to be released as stable in March~April as usual for the annual compiler release, it's been frustrating to see no Zen 5 support even while Intel has already been working on Clear Water Forest and Panther Lake support with already having upstreamed Sierra Forest, Granite Rapids, and other new CPU targets months ago... Well, Granite Rapids was added to GCC in late 2022. But squeezing in as what should now be merged in time is the initial AMD Zen 5 support!..
Qualcomm Hardware Support Increasingly In Good Shape On The Mainline Linux Kernel
After years of work by Qualcomm and Linaro engineers, the Qualcomm SoC support on the mainline Linux kernel has finally matured enough that new hardware support tends to come rather quickly and be well supported. With the forthcoming Linux 6.8 kernel the new Snapdragon 8 Gen 3 can boot on the mainline kernel, the Snapdragon-powered ThinkPad X13s has been popular with Linux developers thanks to the upstream support, and other Qualcomm-powered devices tending to play more nicely with upstream Linux these days rather than having to resort to vendor kernel builds...

Linux Patch Pending To Fix Support For The Transmeta Crusoe CPU
While the Linux kernel has seen increased activity around dropping old/unused hardware drivers and other support, for old hardware that is still proven to be used on upstream Linux kernel releases does stick around and even will see the occasional fix... The latest example of that is a fix on the way for restoring Linux kernel support for the Transmeta Crusoe, the x86-compatible processor released back in 2000...
The Ongoing Open-Source Work To Enable Webcam Support On Recent Intel Laptops
Webcamera support on recent generations of Intel laptops have tended to be a mess due to the Intel IPU6 requiring an out-of-tree kernel driver and a proprietary user-space component. But fortunately thanks to the work of Linar and Red Hat on a "SoftISP" implementation within libcamera, it's becoming possible to leverage these recent MIPI-based webcameras on an open-source software stack...

AMD Ryzen 5 8500G: A Surprisingly Fascinating Sub-$200 CPU
After reviewing the Ryzen 7 8700G and the Ryzen 5 8600G as these new Zen 4 processors with RDNA3 integrated graphics, the latest AMD 8000G series CPU in the Linux benchmarking lab at Phoronix is the Ryzen 5 8500G. The Ryzen 5 8500G is a 6-core / 12-thread processor with RDNA3 graphics that retails for just $179 USD. Here's a look at how it's performing against other AMD and Intel processors on Ubuntu Linux. The Ryzen 5 8500G ends up being decent on the GPU side but making me genuinely excited is the Zen 4C prospects in the low-power space for AI workloads at the edge, low power servers, and other different deployments for great low-power performance. Under load this AVX-512 wielding budget desktop processor was typically pulling 50 Watts or less!
New Linux Kernel Patches Begin Plumbing Rust Support Into Bcachefs Driver

The Mold Linker Is Great & Set To Become Even Better
When it comes to open-source compiler toolchain components and more broadly often unsung heroes in the low-level open-source space, one of the most interesting successes in recent years has been the Mold linker that has proven itself a viable alternative to GNU ld and Gold or LLVM's lld linkers. Mold is already in great shape and typically proving itself well while moving ahead they are working toward kernel/embedded programming support as one of the last grounds to tackle...

Ubuntu 24.04 LTS Leaning Toward Low-Latency Kernel Optimizations By Default
Last month it was noted on Phoronix that Canonical's kernel team is looking at folding their low-latency kernel optimizations into their generic kernel builds. Right now Ubuntu maintains a separate "lowlatency" kernel flavor with Kconfig tweaks in the name of low-latency responsiveness as an alternative to their "generic" kernel default, but for Ubuntu 24.04 LTS it continues looking like they'll move forward with this change of incorporating the changes into their default kernel build...
The Greenfield In-Browser Wayland Compositor Is Fast Enough For Gaming

Rust-Written Stateless Codec Drivers Make A Lot Of Sense
When it comes to making use of the Rust programming language within the Linux kernel, one of the areas where it makes a lot of sense is for the video codec drivers given the amount of unknown/untrusted data submitted by user-space for video processing and it being a wide attack surface for bad actors. With the memory safety features of Rust this can be a big benefit to such drivers and Collabora is currently experimenting with a virtual codec driver Rust implementation to prove the concept...

Orange Pi Neo Coming As A Ryzen 7 + Linux Powered Handheld Device
When hearing of "Orange Pi Neo" this weekend from sources at FOSDEM 2024, I just assumed it was yet another Orange Pi single board computer... But then to hear it's a handheld game console from Orange Pi again gives off the impression of some low-power ARM device. It turns out though that the Orange Pi Neo is a forthcoming AMD Ryzen powered handheld gaming console...
