The past few weeks I've been putting the Lenovo ThinkPad P14s Gen 4 AMD mobile workstation through its paces that is powered by the AMD Ryzen 7 PRO 7840U SoC. Besides uncovering one BIOS issue that is in the process of being resolved, this latest-generation AMD-powered laptop that features 64GB of LPDDR5X memory, 1TB NVMe SSD, and integrated Radeon graphics with 2.8K OLED display has been working out well on modern Linux distributions. Here's a look at this AMD Zen 4 laptop running on Linux and plenty of performance benchmarks for this laptop.

Limited Support For The AMD Pensando Elba SoC Might Finally Land Upstream In Linux 6.7

The first of three parts for MSG_ZEROCOPY preparations for the VirtIO-Vsock driver have been queued into net-next ahead of planned introduction in the Linux 6.7 kernel as another means of achieving greater performance within virtual machines...

Intel Has Another Series Optimizing Linux Performance With PCP High Auto-Tuning

Phoronix - Tue, 09/26/2023 - 20:10
Intel's open-source software engineers are known for many great performance optimizations to the Linux kernel. Over the years Intel has contributed countless performance optimizations to the kernel and related Linux components that have made significant improvements not only for Intel hardware but x86_64 as a whole and at times CPU architecture independent improvements. One of their newest performance optimizing patch series is around Per-CPU Pageset (PCP) high auto-tuning...

Intel's Habana Labs Driver Quietly Drops References To The Greco AI Processor

Phoronix - Tue, 09/26/2023 - 18:40
Announced last year at the Intel Vision conference was the Habana Labs Gaudi2 and Greco AI hardware. Since then we've seen a lot of Linux kernel driver work happen for enabling the Gaudi2 second-generation training and inference AI processor while there hasn't been anything real in the way for Greco, which was the successor to the Goya AI processor. Now references to Habana Labs Greco are being removed from the driver...
