Linux 6.18 With Nouveau Driver Will Default To Using GSP Firmware

Thu, 08/14/2025 - 17:58
A change queued in drm-misc-next for DRM-Next ahead of the Linux 6.18 kernel cycle later this year is promoting the Nouveau driver for open-source NVIDIA GPU support to be using the GSP firmware by default. This reflects the reality that using the NVIDIA GPU System Processor "GSP" firmware with Turing and Ampere GPUs should provide a better experience than the older firmware alternative with Nouveau...

Wed, 08/13/2025 - 20:31
The IDXD Linux kernel driver used for the Data Streaming Accelerator (DSA) support on recent Xeon processors is being cleaned up for some "not so happy code paths" after an Intel engineer uncovered memory leaks and other troubles with the open-source driver code...

Clearing The Last ReiserFS Remnants: Documentation Cleanse Of The Defunct File-System

Wed, 08/13/2025 - 20:18
It was nearly one year ago in the Linux 6.13 kernel that the ReiserFS file-system was dropped from the mainline kernel after having been deprecated in 2022. That dropped 32.8k lines of code from the Linux kernel but some documentation remnants of ReiserFS were mistakenly left in but now in the process of dropping those remnants for the defunct file-system...

Linux Address Space Isolation "ASI" Revived After Lowering 70% Performance Hit To 13%

Wed, 08/13/2025 - 04:53
Several years ago Google engineers began exploring address space isolation for the Linux kernel and ultimately proposing Linux ASI for better dealing with CPU speculative execution attacks. While the hope was it would better cope with the ever growing list of CPU speculative execution vulnerabilities, the effort was thwarted initially by I/O throughput seeing a 70% performance hit. That level of performance cost was unsustainable. But now that I/O overhead has been reduced to just 13%...

AMD Ryzen AI Max+ 395 With Framework Desktop vs. Intel Core Ultra 9 285K Linux Performance

Tue, 08/12/2025 - 21:33
Last week alongside our Framework Desktop review with the AMD Ryzen AI Max+ 395 "Strix Halo" SoC I posted benchmarks of the Strix Halo performance compared to the Ryzen 9 9950X / 9950X3D socketed desktop processors. For those wondering similarly how the top-end Strix Halo SoC in the Framework Desktop competes with the Intel Core Ultra 9 285K "Arrow Lake" flagship in performance and power efficiency, here are those comparison benchmarks.
