Graviton5 CPU Benchmarks: 30% Geo Mean Improvement Over Graviton4

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

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

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

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.

Linux 7.3 To Make It Easier To Disable Syscall User Dispatch

Introduced to the Linux kernel nearly six years ago was the Syscall User Dispatch feature to help with Linux gaming. Specifically, Syscall User Dispatch was developed to help Windows games run on Linux more efficiently. While it was upstreamed in Linux 5.11 for more efficiently intercepting system calls from Windows software under Wine, now in the name of security there are patches working their way to the mainline kernel to more easily disable it...
