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

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

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...

Linux's Multi-Grain Timestamps Short-Lived: Removed From The Kernel After A Few Weeks

Sun, 09/24/2023 - 18:54
One of the new features merged for the Linux 6.6 kernel was multi-grained timestamps for the VFS layer and wiring it up for the EXT4, Btrfs, XFS, and Tmpfs file-systems. This alternative though to coarse-grained timestamps ended up exposing some problems and this week ahead of Linux 6.6-rc3, the feature has been stripped entirely from the kernel...
