Stemming from looking at a proposed Linux kernel patch to alter the Linux kernel's system call number handling, veteran Linux kernel developer Thomas Gleixner went down a rabbit hole of the kernel's system call entry handling to make a number of clean-ups and improvements to the code. That rework to the system call entry handling is now expected to land for the Linux 7.3 kernel cycle...

Alfonso Siciliano, who has been one of the FreeBSD developers leading the effort on adding a KDE-based desktop option to the FreeBSD installer, provided an update on recent work around adding integrating this desktop option...

While the Raspberry Pi 5 is already over two and a half years old, one of the missing elements of its support from the mainline Linux kernel has been the IOMMU driver. We are now seeing Raspberry Pi's downstream IOMMU driver being adapted for mainline with hopes of getting it into the upstream kernel...

Following the recent GA of the AWS M9g series as the first instances powered by the new Graviton5 CPUs, I recently ran benchmarks looking at Graviton4 vs. Graviton5 CPU performance. There was very nice generational gains for the new AWS Graviton processors with the shift from Arm Neoverse-V2 to Neoverse-V3 cores and from DDR5-5600 to DDR5-8800 memory, among other improvements. For those wondering how the Graviton5 ARM server processors compare to AMD EPYC and Intel Xeon, here are some additional comparison data points from the Amazon EC2 cloud.

F&S Elektronik Systeme GmbH has showcased the armStone MX8ULP, a Pico-ITX single board computer based on the NXP i.MX 8ULP processor. The 100 × 72 mm platform targets industrial, IoT, and human-machine interface applications, combining low-power processing, real-time capabilities, and multiple connectivity options. The armStone MX8ULP integrates the NXP i.MX 8ULP SoC, which combines two […]

Similar to Linux 7.2 enabling Eswin SoC support by default in the RISC-V "defconfig" kernel build, UltraRISC RISC-V coverage is also now being enabled by default for RISC-V kernel builds in Linux 7.2...

Linux 7.2-rc3 is now available for testing in working toward the stable Linux 7.2 kernel version coming up in August...

The staging driver fixes that were sent out this week ahead of the Linux 7.2-rc3 release is predominantly made up of hardening the Realtek RTL8723BS WiFi driver. In particular, a number of fixes for addressing out-of-bounds behavior when connecting to "bad" WiFi hosts...

HackerBox has released Issue 0128, titled “Mesh Deck,” a DIY communications platform built around a ProMicro nRF52840 development board, an SX1262-based LoRa module, a GPS receiver, an OLED display, and a miniature QWERTY keyboard. The kit focuses on assembling and configuring a portable Meshtastic node for decentralized messaging without cellular or internet service. The main […]

The Harmonic Firmware Initiative "HFI" is trying to provide a generic, standardized power-on firmware experience for RISC-V boards. Akin to the x86 world with having immediate graphics card initialization to provide a display while the system is booting and also having a BIOS setup utility for system configuration, HFI is trying to do the same for the RISC-V world...

KDE developers continue to be very busy this summer landing more features for the upcoming Plasma 6.8 desktop...

Debian 13.6 is out today as the newest point release of Debian Trixie to ship the latest security fixes and other maintenance updates...

Microsoft has officially unveiled Azure Linux 4.0, the latest version of its open-source Linux distribution designed for cloud infrastructure, enterprise workloads, and modern data centers. Formerly known as CBL-Mariner, Azure Linux has powered Microsoft's internal cloud services for years, but version 4.0 marks its biggest evolution yet by becoming a general-purpose server operating system that organizations can deploy both inside and outside Azure.

Earlier this week NVIDIA confirmed some basic details around their next-gen Rosa CPU that succeeds Vera. Among the public confirmation was that it will feature a "Rigel" Armv9.2-A core iterating on their Olympus core design. With the basic details published, NVIDIA immediately introduced Rigel core support into the GCC compiler. Now they have also upstreamed their initial Rigel core enablement into the LLVM Clang compiler...

After originally announcing Graviton5 last December, recently AWS finally made the M9g and M9gd instances generally available as the first featuring these new in-house ARM server processors for the EC2 cloud. Graviton5 makes use of Arm Neoverse-V3 cores compared to Neoverse-V2 with Graviton4, support up to 192 cores, and feature a higher 3.3GHz clock speed compared to 2.8GHz on the prior-generation Graviton CPUs. Here is an initial look at how the Graviton5 processor performs over Graviton4.

With KDE Plasma 6.7 now having seen a few point releases to further polish this last version with X11 support ahead of Plasma 6.8 going Wayland-only, here are some NVIDIA Linux gaming benchmarks between the X11 and Wayland sessions on Plasma 6.7.2 using the popular Arch Linux based CachyOS.

System76 developers have for the past number of weeks been working on developing a "frosted glass" appearance for the COSMIC desktop environment featured on their Pop!_OS Linux distribution. For Pop!_OS users this frosted glass feature is now available and will become more widespread for other Linux distributions once the next COSMIC release is formally tagged...

Going back to February there was a bug report around the xHCI controller dieing on resume from s2idle when using an AMD Ryzen AI Max+ "Strix Halo" Framework Desktop. In turn all USB devices behind the xHCI controller are lost on resume, but unbinding and binding the driver can restore the functionality without a reboot. After months of back and forth communication, it looks like a solution has been figured out and comes down to a nuance of the PCI spec with needing a brief wait...

Today's batch of AMDGPU Display Code "DC" updates bring a few noteworthy items for benefiting modern hardware under Linux...

In addition to Weston 16 nearing release and its release candidate out today, the Wayland 1.26 release candidate was just issued with a few notable changes on top of the more typical bug fixing...
