As some additional enticing Linux kernel patches posted this week for review, an updated patch series is working to optimize code generation during context switching...

This Black Friday is an in-depth look at the current performance of the open-source NVIDIA Linux driver stack with the Nouveau kernel driver (the Nova driver not yet being ready for end-users) paired with the latest Mesa NVK driver for open-source Vulkan API support. With that NVK Vulkan driver is also looking at the OpenGL performance using the Zink OpenGL-on-Vulkan driver used now for OpenGL on modern NVIDIA GPUs rather than maintaining the Nouveau Gallium3D driver. Plus the Rusticl driver for OpenCL compute atop the NVK driver. This fully open-source and latest NVIDIA Linux driver support was compared to NVIDIA's official 580 series Linux driver. Both RTX 40 Ada and RTX 50 Blackwell graphics cards were tested for this thorough GPU driver comparison.

In addition to the proposed Hierarchical Queued NUMA-aware spinlocks for better performance, another interesting performance-enhancing patch series posted in the past 24 hours for the Linux kernel is for improving the performance of single-threaded tasks running on high core count CPU desktops / workstations / servers...

We eagerly await to see if the AMD ISP4 driver will be ready for mainlining in the imminent Linux v6.19 merge window but it's getting down to the wire and thus looking less likely it will make it unless action is taken in the coming days. Today though a sixth version of this AMD ISP4 image signal processor driver was posted for this last piece of the puzzle in enabling the web camera on the HP ZBook Ultra G1a Strix Halo laptop as well as future Ryzen high-end laptops...

The NTFSPLUS Linux kernel driver as a modern NTFS file-system driver implementation continues quickly taking shape as it aims to become the most performant and feature-rich NTFS read/write driver for Linux systems...

A Huawei engineer has sent out patches proposing HQspinlock as a Hierarchical Queued NUMA-aware spinlock for the Linux kernel. HQspinlock aims to addresss inefficiencies within the Linux kernel's spinlock on modern NUMA-systems due to frequent and costly cross-NUMA cache-line transfers...

Vulkan 1.4.335 released a few hours ago as the latest iteration of this high performance graphics and compute API. With being just a week since the prior update and given the US Thanksgiving week, it's on the lighter side in terms of issues addressed. There is one new extension though and it's a big one: VK_EXT_present_timing is finally merged...

It's been two months since there were any notable Intel Linux engineering departures to note following various layoffs and voluntary departures this year that have unfortunately impacted their Linux/open-source talent. Sadly this US Thanksgiving is a new departure to note: one of Intel's maintainers for the Xe open-source Linux kernel graphics driver is leaving the company. This is for the modern Xe driver used by default since Lunar Lake and playing a pivotal role for Intel Linux graphics moving forward...
