Linux Hardware Reviews & Performance Benchmarks, Open-Source News

Linus Torvalds just released the stable Linux 7.1 kernel and it's coming a half-day early thanks to his travel plans.

Just a day after Arch Linux developers believed they got their malware AUR incident under control with 1,500+ packages affected by malware, another round of of AUR malware is now being discovered. This latest round is more sophisticated as with code obfuscation to better conceal the intent.

A few days back I wrote about Google's Eric Biggers spearheading an AVX-512 implementation of xor_gen() as the Linux kernel function used for generating and validating parity blocks such as for RAID5/RAID6. That initial implementation was yielding up to 41% better performance while a new implementation has now been posted for scoring some additional victories.

Open-source developer Matthias Klumpp wrote a blog post today outlining his recent work developing pkgcli, a new and modern command-line interface (CLI) around the PackageKit package management abstraction layer.

Among Intel's ongoing reduction in open-source projects they maintain, their BigDL open-source project focused on running large language models across Intel XPUs from Core Ultra laptops to discrete GPUs to cloud / data center hardware all in a low-latency manner, is being ended.

Among the changes being considered for the in-development Fedora 45 is a lightened version of the GRUB UEFI bootloader that would focus on being a minimal implementation suitable for confidential computing.

13 June 06:47 AM EDT - Intel - Intel Thermald Comes To ARM

Released on Friday was the newest version of Intel Thermald, the thermal daemon developed by Intel for their processors on Linux for monitoring and helping control temperatures across modern Intel-powered laptops and desktops. Catching me immediately by surprise was Intel Thermald 2.5.12 introducing support for ARM.

13 June 06:20 AM EDT - GNU - Optimize That Code

Earlier this month I wrote about Intel working on function multi-versioning support for APX and AVX10.2 with the GCC compiler. This allows developers to write optimized code paths specifically targeting Advanced Performance Extensions (APX) or Advanced Vector Extensions 10.2 capabilities of future processors while being able to otherwise fall-back to generic or other optimized code paths for other ISA target features. This work is now merged for GCC 17.

The BeOS-inspired Haiku open-source operating system now enables Advanced Vector Extensions 512 on capable Intel/AMD CPUs. A number of other hardware driver improvements were also merged for this interesting OS during the last month.

Last year when releasing Red Hat Enterprise Linux 10.0, Red Hat announced a RHEL 10.0 developer preview for RISC-V. Since then that RISC-V developer preview hadn't been updated but now Red Hat has published a new developer preview snapshot based on RHEL 10.2.

Ever since AMD announced openSIL in early 2023 for open-source CPU silicon initialization to eventually replace AGESA and enhance their Coreboot support, I have been eager to try it out. The openSIL code drops to date though have just focused on select reference platforms with only aiming for production status in the Zen 6 timeframe. But thanks to 3mdeb porting openSIL and Coreboot to a Gigabyte server motherboard, it's now possible to try out openSIL+Coreboot right now on Zen 5 hardware.

On Sunday it's anticipated that Linus Torvalds will released the stable Linux 7.1 kernel. This is a really terrific mid-year update to the Linux kernel! Here's what makes me excited about Linux 7.1.

12 June 11:26 AM EDT - Ubuntu - Ubuntu + Dbus-Broker

Among the many new features planned for Ubuntu 26.10 is switching the default D-Bus implementation over to using the high performance Dbus-Broker drop-in replacement.

One of the exciting additions to the Linux 7.1 kernel is the introduction of the new NTFS file-system kernel driver. While in good shape already and proving advantageous over other NTFS open-source driver options, one of the initial limitations on it is around Windows native symbolic link handling but that is now in the process of being resolved.

Linux cryptography subsystem expert Eric Biggers Eric Biggers of Google worked on some pretty nice Intel/AMD x86_64 optimizations over the years. Especially around AVX-512 optimizations within the Linux kernel's crypto code has been one of his many nice improvements to the kernel in recent times. Today he's out with another enticing AVX-512 optimization and this time it's for the software RAID code.

The Arch Linux User Repository "AUR" was hit by a large-scale malware campaign this week with more than 400 of these user-supplied packages being compromised.

Now in user-space for the Mesa RadeonSI Gallium3D and RADV Vulkan drivers is the GFX1156 (GFX 11.5.6) support being prepared too.

Git 2.55-rc0 is out today as the first tagged test version of the forthcoming Git 2.55 distributed version control system. Most notable with Git 2.55 is that Rust support is being enabled by default.

With Canonical engineers again experimenting with x86_64-v3 package builds for Ubuntu Linux using an "amd64v3" archive for the current Ubuntu 26.10 development, I decided to see how these latest amd64v3 packages comparing to their conventional Ubuntu 26.10 amd64 packages.

It's crazy realizing that glTF 2.0 is already nine years old for this API-neutral 3D runtime and asset delivery format. The Khronos 3D Formats Working Group today extended that with the debut of glTF 2.1 as a backward-compatible revision to the specification.

Open-source developer Jos Dehaes wrote in to Phoronix today in announcing a new X11 server he has been working on from scratch that has been quietly developed to this point but now ready to announce to the world... The YSERVER.

Just a week after the release of Intel XPU Manager 1.3.7, Intel today released XPU Manager 2.0 as a major overhaul for this software for monitoring and management of their data center GPUs on Microsoft Windows and Linux.

An important one-liner is set to come for Linux 7.2 to enable ESWIN SoC support by default for RISC-V kernel builds. This change will allow default RISC-V kernel builds in turn to boot on the likes of SiFive's HiFive Premier P550 developer board.

Lemonade, the local AI server solution developed by AMD that is designed to work across their CPUs, GPUs, and NPUs, is out with a new version today that also adds NVIDIA CUDA support.

After recently noticing the Intel Arc B580 performing better on Linux 7.1 for that kernel version soon to be released as stable, I was curious if there were performance gains also to be found with the new flagship Arc Pro B70 BMG-G31 workstation graphics card. Here are some benchmarks of the Intel Arc Pro B70 in relevant workloads between Linux 7.0 and the near-final Linux 7.1 kernel.

10 June 06:11 AM EDT - Radeon - HDMI 2.1 Compliance Testing

While not as exciting as features like HDMI 2.1 FRL and Display Stream Compression itself, as part of AMD's efforts to provide a fully open-source HDMI 2.1 driver implementation for AMDGPU, new code is being prepped for their kernel driver to support the HDMI compliance testing efforts.

Among the Kernel-based Virtual Machine (KVM) work being queued ahead of the upcoming Linux 7.2 merge window are preparations for supporting Advanced Performance Extensions within KVM virtual machines.

10 June 05:49 AM EDT - Radeon - Better Instruction Cache Prefetching

Initially introduced in RDNA3 (GFX11) GPUs is INST_PREF_SIZE to specify the number of instruction bytes to prefetch prior to a wavefront beginning execution. The Mesa Radeon Vulkan driver "RADV" is now making use of this feature in RDNA3/RDNA4 GPUs for better instruction cache prefetching.

Made public today is CVE-2025-10263 as a "critical" security vulnerability affecting many different Arm CPU cores. CVE-2025-10263 could allow for privilege escalation on affected systems due to a specific timing condition during a memory permission change. Fundamentally it comes down to completion of affected memory accesses might not be guaranteed by the completion of a TLBI.

Alpine Linux, the Linux distribution popular especially for containers / micro-services and embedded devices, is out with its newest feature release.
