Linux Hardware Reviews & Performance Benchmarks, Open-Source News

An unfortunate Linux kernel bug coming to light just ahead of Christmas may cause frustration for some server administrators, particularly public cloud providers... It turns out with the Linux kernel releases since 2022, KVM guest virtual machines making use of Intel Advanced Matrix Extensions (AMX) is possible to cause the host to experience a kernel panic.

Sched_ext as the extensible scheduler code for the Linux kernel that allows loading schedulers from user-space via eBPF code has shown a lot of interesting possibilities. Andrea Righi of NVIDIA who has been heavily involved in sched_ext development shared some of the future plans being looked at as we move into 2026.

If Linux 6.19 switching from the Radeon legacy to AMDGPU kernel drivers for the GCN 1.0/1.1 GPUs for those ~13 year old GPUs isn't nostalgic enough for you, here's something a bit more nostalgic this holiday season: fresh open-source driver commits to the Radeon R300g driver for supporting those 23 year old ATI R300 GPUs up through the 20 year old R500 class graphics processors.

With the upcoming LibreOffice 26.2 open-source office suite release, they are getting rid of the "Community Edition" branding for the standard version of this widely-used cross-platform office suite.

Very talented open-source developer Fabrice Bellard who already is well known for his work on QEMU, the Tiny C Compiler, and FFmpeg, has another accomplishment: Micro QuickJS. The Micro QuickJS JavaScript engine can compile and run JavaScript programs with as little as 10 kB of RAM.

Ahead of Intel Panther Lake laptops expected to debut next month at CES in Las Vegas, the Linux driver support for the next-gen "50xx" NPU of Panther Lake is now complete. The last piece of the driver support puzzle is now in place with the NPU firmware binaries having been upstreamed today to the linux-firmware.git repository.

As an end-of-year tradition at Phoronix for running a lot of year-over-year comparison performance benchmarks and other long-term performance evaluations, it's typically done on the higher-end hardware. That's done for a matter of time savings with maximum performance when running often 100~200+ benchmarks per article, the highest-end hardware typically being the most interesting in terms of features and capabilities, and more often than not getting flagship hardware review samples as opposed to the lower-end hardware. There have been benchmarks recently showing the big gains for AMD EPYC from a one year Linux LTS kernel upgrade, Intel Granite Rapids over the past year, and even the AMD Milan-X performance over the last four years, among other end-of-year 2025 articles. Today is a look at how the AMD Ryzen AI 5 "Krackan Point" CPU/iGPU performance has evolved simply over the last six months. It was a rather surprising twist how much better the Linux performance is over simply the past six months.

The open-source Mesa PowerVR "PVR" Vulkan driver has merged multi-architecture support as part of preparing to add support for newer Imagination GPUs.

Last week a request for comments (RFC) was issued around establishing an LLVM AI Tool Use Policy. The proposed policy would allow AI-assisted contributions to be made to this open-source compiler codebase but that there would need to be a "human in the loop" and the contributor versed enough to be able to answer questions during code review. Separately, yesterday a proposal was sent out for creating an AI-assisted fixer bot to help with Bazel build system breakage.

An interesting anecdote from this month's Linux Plumbers Conference in Tokyo is that Meta (Facebook) is using the Linux scheduler originally designed for the needs of Valve's Steam Deck... On Meta Servers. Meta has found that the scheduler can actually adapt and work very well on the hyperscaler's large servers.

Merged ahead of the upcoming GCC 16.1 stable release of the GCC 16 compiler is initial support for the Armv9.6-A target.

For those still using old AMD GCN 1.0 "Southern Islands" or GCN 1.1 "Sea Islands" graphics cards, the upcoming Linux 6.19 kernel is a wonderful holiday gift. With Linux 6.19, the GCN 1.0/1.1 GPUs are now defaulting to the modern AMDGPU kernel driver in place of the legacy "Radeon" DRM driver that has been the default for GCN 1.1/1.0 and other ATI/AMD graphics processors of the past 2+ decades. In this article is a look at the performance benefit of now AMDGPU being the default as well as now enabling RADV Vulkan support out-of-the-box.

University researchers presented Rex at this month's Linux Plumbers Conference 2025 in Tokyo. Rex is designed for "safe and usable" Rust-based kernel extensions that could serve in place of eBPF programs for extending the Linux kernel functionality.

19 December 12:27 PM EST - Intel - Panther Lake Slow Workload Hints

Five years ago Intel began introducing "workload hints" used for thermal and power purposes with their SoCs and in turn on the software-side being enabled with their INT340X kernel driver on Linux systems. That Intel workload hint coverage was added to the Linux kernel in late 2020 and then a big addition in 2023 with Meteor Lake introducing new workload hint type capabilities. Now patches have been posted to the Linux kernel mailing list for new workload hint functionality coming for upcoming Panther Lake SoCs.

The recently released Linux 6.18 kernel is this year's Long Term Support version. As such it's sure to a see a lot of enterprise and hyperscaler uptake in being the annual LTS kernel version. While Linux 6.12 LTS will be maintained at least through the end of next year, upgrading to Linux 6.18 LTS can be very worthwhile from the performance perspective beyond the extended timeline until it will reach end-of-life. Here are benchmarks showing the performance advantages of upgrading from Linux 6.12 LTS to Linux 6.18 LTS for 5th Gen AMD EPYC "Turin" as well as an early look on the same server for the performance direction Linux 6.19 is bringing the kernel into 2026.
