The PreSonus Quantum 2626 is a high-end, Thunderbolt 3 based audio interface. PreSonus just maintains Windows and macOS drivers for this high-end audio interface while now an open-source Linux driver has been posted after being independently developed via reverse engineering...

With the Intel Xeon 678X "Granite Rapids WS" processor that I have been recently testing within the HP Z4 G6i workstation, there are 48 cores plus with Hyper Threading is a total of 96 threads for this high-end workstation processor with a 300 Watt TDP. For those curious about the performance impact of HT/SMT on this Intel Xeon 600 series workstation processor, here are some comparison benchmarks.

The Linux kernel has supported the CONFIG_COMPAT_32BIT_TIME Kconfig build time option for optionally disabling of legacy 32-bit time system call support. This is intended to disable the code that uses a 32-bit integer for time that is thus not Year 2038 safe, but at the cost of breaking compatibility for legacy 32-bit applications. Even if building without Linux 32-bit time support, it turns out some 32-bit time code persisted but that is now being fixed with Linux 7.3...

In addition to the IOmap improvements helping EXT4 performance in Linux 7.3, the main EXT4 feature pull request has now been submitted for this next kernel version. That pull is set to land yet more performance optimizations for EXT4...

Andrew Morton on Tuesday sent out all of the memory management "MM" updates for the Linux 7.3 merge window. The MM pull was particularly heavy as he noted 1,250 "added-to-MM" emails were sent out this cycle compared to 920 the prior cycle. With a lot of patch churn, he also turned to Google's Gemini AI for writing his patch summaries. In going through the very verbose AI-generated summary, there are two patch series that get me excited on the performance front with Linux 7.3...

COSMIC Epoch 1.6 was released this evening as the latest milestone for this open-source, Rust-based desktop environment led by System76 as part of the work on their Pop!_OS Linux distribution...

There was a proposal under discussion the past few months on building x86-64-v3 packages for Fedora 45 while retaining x86-64-v1 packages. The hope was building the Fedora packages with x86-64-v3 where AVX/AVX2, FMA, BMI2, and other newer ISA features can be assumed in the name of better performance. Unfortunately, the x86-64-v3 plans are now delayed but may be reconsidered next year with Fedora 46...

Merged earlier this year for Linux 7.1 was extended attributes on sockets support as a feature sought after by the likes of GNOME and systemd for helping with Varlink IPC usage and other purposes. A limitation though of the functionality has been no efficient means for a BPF program to read those user extended attribute labels back. But with Linux 7.3 that's being addressed with the new bpf_sock_read_xattr() kernel function...

Nordic Semiconductor’s nRF93M1 Development Kit is now available through multiple distributors, providing a platform for evaluating the company’s nRF93M1 LTE Cat 1 bis cellular module. The board combines the modem with an nRF54L15 host MCU and includes USB-C, onboard J-Link debugging, power-measurement support, and a preloaded SIM card. The nRF93M1 DK pairs the nRF93M1-LABA modem […]

Modular, the AI startup founded by Chris Lattner of LLVM and Swift fame, has open-sourced their Mojo systems programming language! This comes following the recent acquisition of Modular by Qualcomm...

As part of the VFS pull requests now merged to the Linux 7.3 development kernel was an improvement to the IOmap framework used by various file-systems for mapping logical file byte offsets in memory to their physical locations on storage. With the now-merged code, this modern block mapping framework is allowing better performance at least for the EXT4 file-system...

Merged today to Mesa 26.3-devel is a nice performance boost for Intel graphics with Valve's Steam Play when using DXVK for Direct3D 8 / 9 / 10 / 11 over the Vulkan API. The open-source Intel ANV driver is seeing up to 5% better performance with DXVK...

Crowd Supply recently featured the USBridge-KVM 2.0, a compact IP-KVM designed for remote system administration, debugging, and bare-metal recovery. The device provides HDMI video capture, USB keyboard and mouse emulation, virtual media, hardware power control, BIOS text recognition, and an integrated display while operating independently of the target computer’s operating system. The USBridge-KVM 2.0 is […]

Among the early pull requests merged today by Linus Torvalds for the Linux 7.3 kernel cycle were removal of some ancient file-systems while adding in a new pseudo file-system...

Linux kernel developers made a significant last-minute graphics change for Linux 7.2, reverting the DRM GPU scheduler back to its previous FIFO policy by default after the newer fair scheduling implementation caused serious performance regressions. The revert was submitted just before the final Linux 7.2 release after users reported severe slowdowns and desktop freezes under sustained GPU workloads.

Firefox 154 is now available as the newest monthly update bringing a few new features, enhancements, and other alterations to this open-source web browser...

EDATEC’s ED-CLAWBOX is a compact edge AI system based on the Raspberry Pi Compute Module 5. The aluminum desktop system is designed for local OpenClaw deployment and provides Gigabit Ethernet, dual-band Wi-Fi, Bluetooth, dual HDMI outputs, USB 3.0 connectivity, mSATA expansion, integrated audio, and a preinstalled JishuShell management environment. For context, the Raspberry Pi CM5 […]

Linus Torvalds just released Linux 7.2 as stable! After a very busy kernel cycle due to the increased patch and reporting churn due to AI/LLM ages, Linux 7.2 managed to make it out today on-schedule for this feature-packed kernel. Linux 7.2 is going on to power Ubuntu 26.10 and other upcoming Linux distribution releases...

Seeed Studio’s reComputer Classic J5011 and J5012 are a pair of AI development systems based on NVIDIA Jetson AGX Orin modules. The reComputer Classic J5011 uses the 32GB AGX Orin module, while the J5012 steps up to the 64GB version. Both systems are intended as direct replacements for NVIDIA’s Jetson AGX Orin Developer Kit while […]

The Luckfox Lyra PLC is a compact Linux-based programmable logic controller built around the Rockchip RK3506B processor.
