A Phoronix reader pointed out a bug report from 2015 now getting renewed interest... Linux software RAID via MD RAID, DRBD, LVM RAID, and similar software-based solutions can be broken from user-space around O_DIRECT usage. The issue is that these RAID arrays can be put silently into an inconsistent state across disks.

Posted to the Linux kernel mailing list and GNU Binutils mailing list today is an intriguing message from a longtime x86/x86_64 expert around a "a corporate entity other than Intel/AMD" using some x86 opcodes not used by AMD or Intel processors.

With Linux 6.18 now past the merge window and many new features and changes introduced (https://www.phoronix.com/review/linux-618-features), I have begun testing out this kernel on various servers, desktops, and laptops at Phoronix. Linux 6.18 is quite important with expected to become this year's LTS kernel version upon its stable debut in December. Up today is a first look at Linux 6.17 vs. 6.18-rc1 performance using Intel Xeon 6 Granite Rapids server performance.

AOMP 22.0-1 was released on Wednesday as the newest routine update to this downstream of LLVM/Clang/Flang maintained by AMD that continues to carry their latest modifications for enhancing the C/C++/Fortran compiler offloading support to AMD Radeon/Instinct hardware using the likes of OpenMP and OpenACC.

Merged today to LLVM Git for next spring's LLVM 22.0 release is support for the Intel Nova Lake ISA targeting with the "-march=novalake" option.

Just days ago Valve developer Autumn Ashton announced initial NVIDIA DLSS upscaling for the open-source Mesa NVK driver. One of those needed Vulkan extensions, VK_NVX_image_view_handle, is already merged to Mesa Git.

Posted to the Linux networking mailing list on Wednesday were the latest patches for enabling the Homa transport protocol. Homa is the clean-sheet design aiming to become an alternative to TCP within data centers and capable of offering 10~100x reductions in tail latency for short messages.

Announced nearly one year ago was the OpenWrt One as a router/AP that is "hacker-friendly" and open-source. The OpenWrt One is powered by a Filogic 820 SoC and features WiFi 6. This official OpenWrt device is manufactured by Banana Pi. While there is downstream open-source code available for customizing the OpenWrt One to your heart's content, the upstream Linux kernel support to date hasn't been full-featured.

SYCLBIN has been proposed by a longtime Intel compiler expert as a new way for storing SYCL device code for use as part of their GPU/XPU programming ambitions.

The latest Mesa Git code is now under version Mesa 26.0-devel with the Mesa 25.3 code being branched overnight for what will become this quarter's stable feature release.

Arm has been working on an open-source Linux kernel accelerator "accel" driver for their Ethos NPUs. That kernel driver continues being revised and under review for inclusion into a future mainline Linux kernel release. Already though a Gallium3D driver for Mesa has been merged for leveraging the Ethos NPU.

The ollama 0.12.6-rc0 software released this evening and with it comes experimental Vulkan API support.

Valve's open-source Linux graphics team continues carrying out great feats from getting NVIDIA DLSS working on the open-source NVK driver to enhancing Linux GPU driver support for hardware long forgotten about by the hardware vendors. The latest improvement from Valve's stellar group of open-source contributors are some fixes that benefit old Radeon Rx 200 series graphics cards that are more than one decade old.

PyTorch 2.9 is out today ahead of the PyTorch Conference happening next week in San Francisco. Notable with PyTorch 2.9 is better AMD ROCm and Intel XPU installation support via expanded wheel variant support.

Mesa 25.2.5 is out today as the newest bi-weekly point release for these open-source OpenGL and Vulkan drivers. Particularly if you are on Intel graphics of Battlemage or Lunar Lake and potentially older, Mesa 25.2.5 contains a very important bug fix for various rendering issues and potential game hangs/crashes.

It's been four years now since the Open 3D Engine was born out of Amazon's Lumberyard project and hosted by the Linux Foundation. Today marks the release of the Open 3D Engine "O3DE" 25.10 release with the newest features and fixes for this cross-platform game/graphics engine.

In preparation for Panther Lake laptops shipping in early 2026, after Intel appears to have largely wrapped up work on the Linux driver enablement they are now ensuring the necessary firmware bits are out in time.

Last week Amazon/AWS announced the new EC2 M8a instances as their latest-generation, general-purpose compute instances now powered by AMD EPYC 9005 "Turin" processors. Amazon announced the M8a as having up to 30% higher performance and up to 19% better price performance over M7a. With my testing of both at 32 vCPUs, the new AMD EPYC Turin instance provided 1.59x the performance over the prior-generation EPYC Genoa instance!

Apple today announced the M5 SoC as the newest in the Apple Silicon family and with claims of 4x the peak GPU compute performance for AI of the M4.

Merged today to the Tinygrad deep learning framework is a Mesa NIR back-end to allow targeting that common intermediate representation used by these open-source Linux GPU drivers. Initially supported with this Tinygrad NIR back-end is the open-source NVIDIA Vulkan driver "NVK" with its Rust-based NAK compiler as well as the CPU-based LLVMpipe driver.
