8-Way Linux OS Comparison On The Framework 12: Squeezing More Performance Out Of Raptor Lake

16 juillet 2025 à 18:20
Earlier this year when the Framework 13 was updated for the AMD Ryzen AI 300 series I ran benchmarks looking at the performance gains across different Linux distributions with Debian 13, Clear Linux, and CachyOS being the outstanding performers for that Strix Point hardware. With the recent launch of the Framework 12 2-in-1 laptop powered by Intel Raptor Lake you may be wondering what Linux distributions have the edge there. Here is an eight-way comparison of different Linux operating systems on the Framework 12 with Intel Core i5 1334U with the likes of Arch Linux, CachyOS, Clear Linux, Debian, Fedora, openSUSE, and Ubuntu.

More AMD FidelityFX Super Resolution 4 Improvements Land For Open-Source Driver

16 juillet 2025 à 16:10
It's a very busy week for the open-source OpenGL and Vulkan drivers leading up to the Mesa 25.2 code branching. On top of RADV ray-tracing improvements, Vulkan 1.2 conformance for Kepler GPUs, Xe3 Panther Lake graphics enabled by default, and many other last minute changes, over the past week has also been a push getting more AMD FidelityFX Super Resolution 4 "FSR 4" improvements merged for the Radeon RADV driver...

Additional AMD RDNA3 & RDNA4 Ray-Tracing Improvements For Mesa 25.2 RADV

16 juillet 2025 à 02:22
Ahead of the Mesa 25.2 feature freeze and code branching expected later this week, some additional ray-tracing optimizations were merged today for the Radeon "RADV" Vulkan driver. These latest RADV ray-tracing improvements benefit the latest Radeon RX 9000 series "RDNA4" the most but there are also some optimizations too for RDNA3 class GPUs...

Latest Intel Engineering Layoffs Lead To An Intel Linux Driver Being Orphaned

15 juillet 2025 à 12:38
The latest round of cost-cutting at Intel seems to be having a larger impact on their software engineering efforts than some of their previous rounds of layoffs. In addition to a prominent Linux kernel developer veteran leaving Intel last week where he worked for the past 14 years and responsible for many great upstream improvements, other Intel software engineers working on their Linux/open-source affairs have also been departing. In just the latest instance, one of the upstream Intel Linux kernel drivers is now "orphaned" due to the developer departing and no one experienced left to maintain the code...

RADV Lands Experimental Host Image Copy Support (VK_EXT_host_image_copy)

15 juillet 2025 à 11:55
Making it into the RADV Vulkan driver ahead of this week's Mesa 25.2 feature freeze is experimental support for the VK_EXT_host_image_copy extension. The Vulkan host image copy extension was worked on by Valve and others for letting applications/games copy data between the host memory and images on the host processor without having to first stage via a GPU-accessible buffer...

New Effort To Upstream LTTng In The Linux Kernel Draws Criticism From Torvalds

15 juillet 2025 à 02:37
The LTTng tracing toolkit is twenty years old this year and it's seen significant adoption by different hyperscalers and other notable organizations like IBM and Sony and Siemens beyond basic end-users and administrators for system tracing/debugging. While having many successes over the past two decades, the kernel modules remain outside of the kernel tree. Even with around four different upstreaming attempts to get the LTTng code into the mainline kernel, it still has not happened. A fifth attempt began today but still looks like it could be an uphill battle...

Mesa 25.2 NVK vs. NVIDIA R575 Linux Graphics Performance For GeForce RTX 40 Series

14 juillet 2025 à 17:38
A number of Phoronix readers have been interested in seeing some fresh benchmarks of Mesa's NVK Vulkan driver in providing open-source Vulkan API support on NVIDIA GeForce graphics cards as well as the modern OpenGL approach of using Zink for layering OpenGL atop Vulkan. Here are some fresh benchmarks using the very latest Mesa 25.2 code for NVK on the latest upstream stable Linux kernel compared to the NVIDIA R575 official Linux graphics driver stack.
