The AMD EPYC 9005 "Turin" processors that launched last year offer excellent performance and power efficiency out-of-the-box. For those wanting to pursue maximum power efficiency and running in the most optimal configuration for performance-per-Watt, AMD EPYC BIOS tunables as well as recent Linux kernel driver improvements can help in driving even greater efficiency. Today's article is a look at the impact of the AMD P-State driver usage and options with recent kernel versions as well as the Power Profile Selection BIOS option for the impact on 5th Gen EPYC performance and power efficiency.

We are nearing one year since the first Qualcomm Snapdragon X1 Elite laptops shipped with Windows 11 ARM.

The debate over the Linux kernel's Rust programming language policy continues... While some kernel maintainers are against it, Linus Torvalds has reportedly said he would override maintainers that may be against honoring Rust code. Linux's second-in-command Greg Kroah-Hartman has also been a big proponent of Rust kernel code. He's crafted another Linux kernel mailing list post today outlining the benefits of Rust and encouraging new kernel code/drivers to be in Rust rather than C...

One of the most logical paths forward for the Servo web browser engine is making it compelling for embedding within applications as an alternative to the Chromium Embedded Framework (CEF), WebKitGTK, and other browser engines. Servo developers recently realized though it's around 200 lines of Rust code to embed Servo compared to around 50 lines of C code if targeting WebKitGTK... So improvements are being made to the Servo embedding API...

One of the AMD software projects we are very bullish on for the future is openSIL for opening up more of the CPU silicon initialization code for what will eventually replace AGESA across all client and server processors that is aiming for production readiness with Zen 6. In turn, AMD openSIL should allow easier/better Coreboot support. One of the development milestone release targets did slip but they remain working on preparing AMD openSIL releases for Phoenix client and Turin server hardware...
