With last week's launch of Intel's 4th Gen Xeon Scalable Sapphire Rapids server processors, Intel heavily talked up the shiny new accelerators and the big performance potential of AMX, but not really showcased and only heard through the grapevine was the improved AVX-512 implementation found with these new processors. With Sapphire Rapids there is reduced penalties from engaging AVX-512 -- and for some AVX-512 instructions, no longer any measurable impact -- compared to prior generation Xeon processors. In this article is a look at the performance for a wide variety of workloads with AVX-512 on/off not just for Sapphire Rapids but also for prior generation Ice Lake as well as AMD's new EPYC 4th Gen "Genoa" processors where they have introduced AVX-512 for the first time.
Last month a change proposal was filed for aiming to yield faster reboots and shutdowns of Fedora Linux by shortening the time window that services can block the shutdown process. A modified version of that change proposal has now been cleared by the Fedora Engineering and Steering Committee...

With AMD Zen 4 processors there is a new Automatic IBRS (Indirect Branch Restricted Speculation) similar to Intel's Enhanced IBRS (eIBRS) functionality for offering lower-overhead Spectre V2 mitigations compared to the Retpoline approach used on Zen 3 and prior. Finally with Linux 6.3 that Auto IBRS support is now set to be merged...
Over the past year NVK has taken shape as a -- currently out-of-tree -- Mesa Vulkan driver for supporting NVIDIA graphics hardware. This open-source NVIDIA Vulkan driver is inching closer to the point of being upstreamed into Mesa, but before it's usable for gamers/enthusiasts there is kernel work that must happen too...
One of the exciting announcements Intel made just before Christmas was announcing their work on the new "Xe" kernel graphics driver for Linux.

With Intel's 4th Gen Xeon Scalable "Sapphire Rapids" processors that launched this week, Intel is betting heavily on the integrated accelerators for offering them an advantage over competitors for modern hyperscaler tasks and other workloads able to take advantage of the In-Memory Analytics Accelerator (IAA), Data Streaming Accelerator (DSA), QuickAssist Technology (QAT), and the Dynamic Load Balancer (DLB). But what does the software landscape currently look like and what's needed to actually make use of these accelerators under Linux? Here is a brief how-to guide / overview for making use of the accelerators on your Linux server.
