CentOS Stream 10 defines the upstream Red Hat Enterprise Linux 10 that the RHEL 10 minor versions are created from and ultimately a preview of what's coming down the pipe for future RHEL 10 releases. CentOS Stream 10 had been available in a preview phase since earlier this year while now is considered GA...

While Fedora Workstation has defaulted to using the Btrfs file-system for the past four years, only this past summer was the idea raised of creating a Fedora special interest group (SIG) around Btrfs to help advance efforts around this CoW file-system for Fedora Linux integration. This week marks the Fedora Btrfs SIG officially being established...

Last week Intel announced the Arc B-Series Battlemage graphics cards as their first Xe2 discrete GPUs. Ahead of the Arc B580 graphics card hitting Internet retailers tomorrow, today the review embargo lifts on the Intel Arc B580. Here is what to expect from the Linux driver support at launch for the Intel Battlemage graphics cards and how the Arc B580 is performing for Linux gaming/graphics workloads.

Now that the initial Intel Arc B580 graphics card gaming review on Linux is out, for productivity-minded users you may be more curious about the GPU compute potential... Here are some initial OpenCL and Level Zero results for the Intel Arc B580 graphics card compared to the Intel Arc A-Series and the AMD Radeon and NVIDIA GeForce competition under Linux.

Earlier this month as part of patches for cleaning up x86 32-bit kernel code for x86_64 systems, there was a patch to drop support for 32-bit x86 KVM host support. That patch has now been split off into its own patch series with also now raising the prospects of ending 32-bit KVM host support across all CPU architectures rather than being just an x86-only change...

While the Linux 6.13 merge window only recently ended and that kernel won't be out until around the end of January followed by the start of the Linux 6.14 merge window, Intel software engineers on Wednesday sent out their first two pull requests to DRM-Next of new kernel graphics driver features they are readying for this next version of the Linux kernel...

With the in-development Linux 6.13 kernel one of the biggest features for those using new AMD EPYC 9005 "Turin" processors is using the AMD P-State driver by default for servers/motherboards with ACPI CPPC support enabled. But even for platforms without that where ACPI CPUFreq remains the default, the Linux 6.13 kernel is still showing some nice incremental uplift at large on these new AMD server processors. Here are some Linux 6.11 vs. 6.12 vs. 6.13 Git kernel benchmarks using an AMD EPYC 9575F 64-core server.

Going back to April 2024, SiFive announced the HiFive Premier P550 as an interesting RISC-V developer board to succeed their HiFive Unleashed that was a nice little RISC-V board. There were delays in shipping the HiFive Premier P550 but they have been making progress and are now ready to ship Ubuntu 24.04 LTS pre-installed on this RISC-V board. They have also lowered the pricing on these RISC-V boards...

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...

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...
