Broadcom BCM5770X Networking Driver Support Heading To Linux 6.17

15 juillet 2025 à 15:30
One month ago there was the report on Phoronix of the Broadcom "BNGE" open-source driver being published for forthcoming BCM5770X networking chipsets. That new Broadcom BNGE driver is now set to be introduced in the upcoming Linux 6.17 kernel for supporting the new Broadcom wired networking hardware at up to 800 Gigabit speeds...

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

15 juillet 2025 à 10:38
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 09:55
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 00:37
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 15:38
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.

Old Radeon HD 2000/3000/4000 GPUs Still Seeing Open-Source Driver Fixes In 2025

14 juillet 2025 à 13:01
In addition to last minute feature work on the latest AMD RDNA4 graphics cards ahead of the Mesa 25.2 code branching, there's also some new fixes going into Mesa for the open-source Radeon driver code... Coming in this Monday morning by surprise are some fixes for the Radeon HD 2000/3000 series approaching two decades old as well as a fix for the Radeon HD 4000 graphics processors...

RADV Vulkan Video Improvements Make It Into Mesa 25.2 For AMD RDNA4 GPUs

14 juillet 2025 à 11:07
Ahead of the Mesa 25.2 code branching / feature freeze expected later this week, last minute feature additions and other changes continue landing in the codebase for these open-source OpenGL and Vulkan drivers. One of the additions today worth mentioning are continued Vulkan Video improvements for AMD Radeon graphics...

Intel Mesa Drivers Add Option To Disable Xe3's Variable Register Thread "VRT" Feature

14 juillet 2025 à 10:42
One of the interesting new additions with the upcoming Intel Xe3 integrated and discrete graphics is the Variable Register Thread "VRT" feature. Making use of Variable Register Thread can reduce register splitting, reduce bandwidth consumption, and improve overall performance. More background information on Intel VRT can be found in that aforelinked Phoronix article. But now the ability is coming to optionally disable VRT...
