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...

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.

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.
