M5Stack’s new PaperMono and PaperMono-Lite are compact ESP32-S3-based e-paper development platforms built around a 3.97-inch grayscale touchscreen. Both models include Wi-Fi, microSD storage, an IMU, real-time clock, frontlight, microphone, buzzer, and an integrated 1150mAh battery, while the higher-end PaperMono adds LoRa and NFC connectivity. Both devices are based on the ESP32-S3R8, which integrates a dual-core […]

All of the networking subsystem feature updates were merged today for the Linux 7.3 kernel's merge window. There are a lot of wired and wireless networking improvements this cycle but also a ton of bug fixes -- including many not so important fixes spun up by AI/LLM agents. The networking subsystem maintainers admit now they are "completely overwhelmed" due to this code churn from the output of AI large language models...

FSCRYPT is the Linux file-system encryption framework for supporting per-directory, transparent encryption. FSCRYPT so far is used by the likes of EXT4, F2FS, and CephFS. For Linux 7.3 there is an important clean-up to the FSCRYPT code to simplify it while also opening the door for new features moving forward into future kernel versions...

Intel's open-source Mesa drivers for Iris Gallium3D (OpenGL) and ANV (Vulkan) on Linux are no longer treating next-gen Nova Lake processors with integrated graphics as experimental and off-by-default. With today's Mesa 26.3-devel code, the Intel driver code across Nova Lake's S, U, H, and HX product families are considered stable and enabled by default...

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.
