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'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...

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...

A major update to OCRmyPDF is now available, the open-source project that can work on scanned PDFs and other PDF documents to add an optical character recognition (OCR) text layer to files for allowing them to be searched or copy-pasted. OCRmyPDF makes it a breeze in dealing with scanned PDF text files and now with OCRmyPDF v15 is even better...

Queued up into the Btrfs file-system driver's "for-next" branch ahead of the Linux 6.7 cycle is the Temp-FSID (Same-FSID) feature that is being pursued for use by Valve's Steam Deck game console. The functionality is to overcome a limitation of allowing Btrfs to mount two different devices holding the same file-system image and therefore the same file-system ID...

Since announcing the Advanced Performance Extensions (APX) and AVX10 back in July, Intel's open-source compiler engineers have been busy preparing the GCC and LLVM/Clang compiler toolchains for these major CPU extensions to be found with future Intel processors...

Last month the Downfall CPU security vulnerability was disclosed that impacts various AVX/AVX-512 workloads. Now that there's been a few weeks for the Linux kernel code to settle around the mitigation and the latest Intel CPU microcode becoming more broadly available, here is a fresh look at the performance impact of the Downfall mitigation on affected AVX workloads.

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...

While Intel divested its storage business and Intel Optane was sadly discontinued, one of the interesting open-source software projects from its storage efforts has been DAOS, the Distributed Asynchronous Object Storage engine. Version 2.4 of the DAOS software-defined object store designed for high-speed storage was released this past week...

Prominent GNOME developer Christian Hergert announced he created a new terminal emulator that is twice as fast as the closest GPU-based renderer he's found yet so far on Linux, which was Alacritty. Unfortunately though he currently doesn't have any plans to develop this experimental speedy terminal emulator any further...

With Meteor Lake comes the introduction of the Versatile Processing Unit (VPU) that is now marketed by Intel as the Neural Processing Unit (NPU). Recent versions of the Linux kernel have the "IVPU" accelerator driver to support Meteor Lake's VPU/NPU while now a patch is pending to extend that support for next-generation Arrow Lake processors...

The Wayland Color Management protocol has been years in the making and is needed for a client to specify the color space and HDR metadata of a surface.

Released on Thursday was VKD3D 1.9 as the newest feature update...

AMD used to release new AMDVLK Vulkan driver updates on a near weekly basis for Linux users but that has slowed down for a while. We are approaching the end of Q3 and now AMDVLK 2023.Q3.2 has been published as their first new open-source driver release since early August...

This shouldn't come as any surprise to any longtime Phoronix readers and dedicated open-source/Linux enthusiasts, but Valve with their work on the Steam Deck and SteamOS have been lifting the open-source ecosystem as a whole.

With the new Linux 6.5 kernel stable series one of the many new features is defaulting to the AMD P-State driver with the EPP/active mode compared to the long-used default of the ACPI CPUFreq driver. As shown in various Phoronix articles this can help with the mobile/desktop performance with this new default change while this article is looking at the Ryzen for server benefits too.

Amid all the recent chatter around Bcachefs working its way toward mainline and all the ongoing improvements to existing Linux file-systems, you may have forgotten about Puzzlefs as the new file-system aiming to be an optimal solution for containers and with a kernel driver written in the Rust programming language...

Over the summer the AMDGPU compiler back-end in upstream LLVM began with new targets for GFX1150 and GFX1151 which given all things known are likely the "RDNA3 Refresh" APUs. That work started out light with not much in the way of different code paths from the existing GFX11 support but we're beginning to see some new instructions added for the RDNA3 refresh graphics processors...

There's just under one month to go now until the X.Org Developers' Conference (XDC) returns to A Coruna, Spain for the annual development conference focused on open-source graphics drivers (Mesa), Wayland, and related Linux display/graphics infrastructure although the X.Org Server itself hasn't received much attention in recent years. Here's a look at some of the planned talks for the exciting XDC 2023...

When it comes to Glibc HWCAPs for allowing the C library to load optimized libraries based upon the CPU features at run-time, it's mostly been focused on the x86_64 world for targeting higher x86-64 levels or being able to load optimized libraries for systems with AVX support. Loongson though has now contributed initial LoongArch HWCAPs support...

While Simultaneous Multi-Threading (SMT) isn't as common on Arm SoCs as it is in the x86 and POWER worlds, there are some SMT-capable designs like with the HiSilicon Kupeng 930 for Arm servers. HiSilicon engineers are working now to extend Linux's SMT run-time controls to work on ARM64 (AArch64)...

As a continuation of last week's article looking at Linux 6.6 bringing some impressive gains for AMD EPYC Bergamo, over the past few days I've also tested Linux 6.5 stable and Linux 6.6 Git on Genoa and Genoa-X processors as well as Intel Xeon Scalable "Sapphire Rapids" in looking at this next kernel version's performance. The Sapphire Rapids performance was largely flat while for an interesting class of workloads the Linux 6.6 performance drives the AMD EPYC server performance much higher.
