Linux DT Patches Provide Very Basic Support For Apple M3 Pro / Max / Ultra

10 juillet 2026 à 10:26
Upstreamed for the Linux 7.2 kernel was initial support for booting Linux on the Apple M3 SoC devices. But just the barebones suppport for booting with not yet any accelerated graphics or other typical function needed for daily use of M3 Apple devices on Linux, just booting to a console. Now this work is complemented by additional Device Tree patches for also booting M3 Pro / Max / Ultra devices on Linux...

HiZ Plane Optimization Merged For Intel Vulkan Linux Driver For Some Performance Benefit

10 juillet 2026 à 10:13
After two years being on the TODO list for a possible performance optimization, the Intel open-source "ANV" Vulkan driver has now merged an HiZ plane optimization that can yield up to a few percent frame-rate improvement for Linux gaming/graphics on newer Intel integrated and discrete graphics hardware...

LLVM Clang Merges Initial Support For NVIDIA Rigel Core With Next-Gen Rosa CPU

10 juillet 2026 à 09:52
Earlier this week NVIDIA confirmed some basic details around their next-gen Rosa CPU that succeeds Vera. Among the public confirmation was that it will feature a "Rigel" Armv9.2-A core iterating on their Olympus core design. With the basic details published, NVIDIA immediately introduced Rigel core support into the GCC compiler. Now they have also upstreamed their initial Rigel core enablement into the LLVM Clang compiler...

Graviton5 CPU Benchmarks: 30% Geo Mean Improvement Over Graviton4

9 juillet 2026 à 17:53
After originally announcing Graviton5 last December, recently AWS finally made the M9g and M9gd instances generally available as the first featuring these new in-house ARM server processors for the EC2 cloud. Graviton5 makes use of Arm Neoverse-V3 cores compared to Neoverse-V2 with Graviton4, support up to 192 cores, and feature a higher 3.3GHz clock speed compared to 2.8GHz on the prior-generation Graviton CPUs. Here is an initial look at how the Graviton5 processor performs over Graviton4.

Proposed Linux Patch For A Brief Delay To Match PCI Spec Will Hopefully Address Some Bugs

9 juillet 2026 à 13:35
Going back to February there was a bug report around the xHCI controller dieing on resume from s2idle when using an AMD Ryzen AI Max+ "Strix Halo" Framework Desktop. In turn all USB devices behind the xHCI controller are lost on resume, but unbinding and binding the driver can restore the functionality without a reboot. After months of back and forth communication, it looks like a solution has been figured out and comes down to a nuance of the PCI spec with needing a brief wait...

AMD Ryzen AI Halo Box RGB LED Driver Inches Closer To The Mainline Kernel

9 juillet 2026 à 10:13
The AMD Ryzen AI Halo mini PC powered by Ryzen AI Max+ "Strix Halo" began shipping this week. It features very nice Linux support out-of-the-box with the Debian-based Ryzen AI Developer Platform operating system. For those wishing to run their own x86_64 Linux distribution, one of the only caveats in the Linux support is quite small... No mainline kernel support yet for controlled the RGB LED light strip on the driver. But that driver is coming and will hopefully be mainlined soon...

Single vs. Dual Channel Memory Performance With The Intel Core Ultra 7 270K Plus

8 juillet 2026 à 14:48
Given today's pricing environment around system memory, a Phoronix Premium supporter recently requested some benchmarks to quantify the performance difference from single to dual channel memory. In considering a new computer build, he is contemplating whether to go for a single stick of DDR5 memory until memory prices hopefully subside in the future. For those in a similar boat, here are some benchmarks of single versus dual channel memory on an Intel Core Ultra 7 270K Plus "Arrow Lake" desktop.
