Back at the 2024 LLVM Developers' Meeting was an interesting presentation by AMD engineer Joseph Huber for how they have been exploring running common, standard C/C++ code directly on GPUs without having to be adapted for any GPU language / programming dialects or other adaptations...

QEMU 9.2 is out today for this processor emulator that plays an important role within the open-source Linux virtualization stack...

The BeOS-inspired Haiku open-source operating system project is out with a new monthly status update to detail their latest efforts...

Complementing yesterday's fresh Linux gaming benchmarks of mid-range Intel Arc Graphics "Alchemist" vs. NVIDIA GeForce RTX 40 vs. AMD Radeon RX 7000 series cards ahead of the upcoming Battlemage availability, today's article is providing a fresh look at the latest Intel Compute Runtime performance for Level Zero / OpenCL on current-gen Intel discrete graphics compared to mid-range AMD Radeon GPUs on ROCm 6.3 and similar NVIDIA GeForce RTX 40 Ada graphics cards on the R565 driver.

Coincidentally coming one day after the GNU Shepherd 1.0 service manager release, the systemd 257 release is now shipping as the newest feature release for this widely-used service manager / init system to Linux systems. Systemd 257 brings a number of new features and improvements for powering late 2024 and early 2025 Linux distributions...

While the Ubuntu desktop has been offered the newer GNOME Console as an alternative to GNOME Terminal, there's been a recent fondness around Ptyxis and apparently is becoming the recommended replacement to GNOME Terminal for the Ubuntu camp...

Last week I wrote about Linux patches cleaning up x86 32-bit kernel builds for x86_64 CPUs. The new iteration of those patches were sent out today, including the addition of a patch adding the CONFIG_X86_64_NATIVE Kconfig tunable for enabling "-march=native" kernel builds to cater your optimized kernel compilation for the CPU on which you are building the kernel...

Currently the Linux kernel's "perf" performance monitoring subsystem has a limit on 2,048 CPU cores for its CPU map that is set by the MAX_NR_CPUS value. But that's becoming not enough in today's high core count era that patches are looking to raise it to a 4,096 CPU core limit by default...

For those wanting to run Coreboot or Coreboot-derived firmware on a modern desktop motherboard with good performance and features, the main contender currently is 3mdeb's Dasharo downstream that can be flashed on the MSI PRO Z790-P/Z790-P motherboards for using with Intel Core Alder Lake and Raptor Lake processors. Firmware consulting firm 3mdeb today published a new Dasharo firmware update for the MSI PRO Z790-P WIFI motherboard...

A promising patch for the Linux kernel is optimizing the locking contention and scattered address space for the MD bitmap code to improve both the storage throughput and latency...

IBM engineers announced they are deprecating the upstream CXL and CXLFLASH Linux kernel drivers with plans to then remove the drivers from the mainline kernel the following cycle. Before getting too worked up when seeing the "cxl: Deprecate driver" patch, this is about the Coherent Accelerator Processor Interface (CAPI) that predates the Compute Express Link...

The Servo browser engine project is out with their latest monthly status update to outline improvements made to this Rust-based open-source engine...

NVIDIA published EGL-Wayland 1.1.17 on Monday as the newest update to this Wayland EGL external platform library to provide client-side Wayland support to EGL atop the EGLDevice and EGLStream extensions...

Back in May for the Linux 6.10 kernel the initial bits of the NTSYNC driver was upstreamed for helping to emulate the Windows NT synchronization primitives so Windows games running under Wine/Proton (such as Valve's Steam Play) can enjoy a very nice performance boost. That NTSYNC code for Linux 6.10 wasn't yet in functioning shape and now a half-year later the newest NTSYNC patch series has been sent out for review...

GNU Shepherd as a service manager for both system and user services that is used by Guix and relying on Guile Scheme has finally reached version 1.0. For those not pleased with systemd, GNU Shepherd can be used as an init system and now has finally crossed the version 1.0 milestone after 21 years of development...

It's been a few months since running any fresh Linux graphics driver comparison benchmarks. But given the imminent availability of the first Intel Arc Battlemage graphics cards, I have been carrying out some fresh Linux GPU driver testing. Given the recently-stabilized NVIDIA R565 Linux driver series and then also the newest upstream code in Linux 6.13 Git and Mesa 25.0-devel for the AMD Radeon and Intel Arc Graphics hardware on their open-source drivers, here is a fresh look at where Intel / AMD / NVIDIA mid-range graphics stand today on Ubuntu Linux with the leading-edge drivers.

Video and image encoders/decoders written in the Rust programming language for its memory safety guarantees is often viewed as one of the compelling areas for the programming language to better protect against malformed/malicious content especially within web browsers. Not only are Rust-based PNG image decoders proving to be more secure than C-based decoders, but the performance of the Rust solutions can be even faster...

For those wishing to kick off the new week with some interesting technical videos and are into compiler tech, the video recordings from the 2024 LLVM Developers' Meeting are now online...

For those with the ASUS TUF GAMING X670E PLUS as a ~$230 USD AM5 motherboard for Ryzen 7000/9000 series processors, this desktop motherboard is seeing support tacked onto the asus-ec-sensors hardware monitoring driver so you can enjoy working sensor readings under Linux...

Ahead of the GNU C Library "glibc" 2.41 release due out around early February, more C23 features are being finished up. The latest crossing the finish line is support for C23's sinpi, cospi, and tanpi trigonometric functions...
