For those using Microsoft's exFAT file-system under Linux for the likes of flash drives and SD cards, a new patch series posted today aims to enhance the read performance. The new patches are shown to improve performance by about 10% while also heaving lower overhead.

Chi Zhiling with the Chinese Linux distribution Kylin OS posted the patch series today for adding multi-cluster mapping support to Linux's exFAT file-system kernel driver. This multi-cluster mapping allows for faster read performance, especially for sequential

The Arch Linux based CachyOS has been quite popular with Linux gamers and enthusiasts for offering leading out-of-the-box performance, especially following the shutdown of Intel's Clear Linux. CachyOS has developed quite a following on the Linux desktop while looking ahead to 2026 they will be working on a server edition.

The CachyOS project today posted their 2025 year-end look at their accomplishments and statistics/milestones. They made a lot of progress this year from new optimizations and features to

As a wonderful Christmas gift to open-source fans, NVIDIA dropped their proprietary license on the CUDA Tile intermediate representation and has now made the IR open-source software.

Earlier this month with CUDA 13.1 NVIDIA announced the CUDA Tile programming model as " the largest and most comprehensive update to the CUDA platform since it was invented two decades ago " The intermediate representation (IR) to CUDA Tile is now open-source software.

The Linux 6.19 kernel has been a bit bumpy in the scheduler department but at least one fix is on the way for addressing fallout.

Linux 6.19 does bring some nice performance improvements overall but during my early testing there were some regressions and I ended up bisecting some of them to the scheduler changes in Linux 6.19 .

Intel's Kernel Test Robot did also report a scheduler regression with Schbench using a Phoronix benchmark run:

"kernel test robot noticed a 52.4%

For X11/X.Org fans there is a new Christmas surprise: Phoenix as an in-development X Server written from scratch using the Zig programming language.

Phoenix is a new X Server written from scratch in the Zig programming language for providing better safety. Phoenix hopes to become a modern alternative to the X.Org Server but admittedly right now is "not ready to be used yet" although it can render simple applications with GLX, EGL or Vulkan.

Phoenix hopes to be simple, secure, better

When it came to the most viewed AMD Linux/open-source news of 2025 there were a lot of accomplishments for the company this year both on the CPU and graphics side of the house and from consumer to server hardware. Today is a look back at the most popular Intel open-source/Linux news of the year, which unfortunately, their layoffs and other cuts to their software engineering were attracting a lot of interest.

Google's Propeller is a profile-guided, reflinking optimizer for large codebases. Propeller is built atop LLVM and can allow for whole-program optimizations. Google compiler engineers are now hoping to bring the Propeller tool into the upstream LLVM codebase.

Google's Propeller has been in the works for several years for speeding up the performance of large binaries/applications . They have even used AutoFDO and Propeller on Linux kernel builds for 5~10% performance improvements .
