But now it seems they are trying again with a new crowd-funded smartphone.
Linux GPIB Drivers Declared Stable – 53 Years After HP Introduced The Bus
Merged to the mainline Linux kernel last year was GPIB drivers in the kernel’s “staging” area. GPIB is the General Purpose Interface Bus launched by HP back in 1972 for lab equipment and more. After a year of cleaning up the code in the kernel’s staging area, for Linux 6.19 the GPIB drivers have been promoted out of the staging area and into the Linux kernel proper. The Linux kernel now has stable driver support for this 8 Mbyte/s parallel bus that was introduced 53 years ago.

AMD RDNA3/RDNA4 Go Down Hard On Linux 6.19, But Here’s How The Older AMD GPUs End Out 2025
As part of the various end-of-year benchmarking comparisons on Phoronix and with Linux 6.19 switching older AMD GCN 1.0/1.1 graphics cards to the AMDGPU driver by default, I planned for a very large AMD Radeon graphics card comparison on the latest open-source Linux driver for ending out 2025. In the end though I was thwarted by newer AMD RDNA3 / RDNA4 graphics cards regressing hard on Linux 6.19 that led to ending this testing prematurely due to a show-stopping bug. In any case in this article offers a fresh look at older GCN and RDNA graphics cards on Linux 6.19 + Mesa 26.0-devel.
Linux 6.19’s Significant ~30% Performance Boost For Old AMD Radeon GPUs
For those still using old AMD GCN 1.0 “Southern Islands” or GCN 1.1 “Sea Islands” graphics cards, the upcoming Linux 6.19 kernel is a wonderful holiday gift. With Linux 6.19, the GCN 1.0/1.1 GPUs are now defaulting to the modern AMDGPU kernel driver in place of the legacy “Radeon” DRM driver that has been the default for GCN 1.1/1.0 and other ATI/AMD graphics processors of the past 2+ decades. In this article is a look at the performance benefit of now AMDGPU being the default as well as now enabling RADV Vulkan support out-of-the-box.
AMD Radeon RX 9000 Series vs. NVIDIA GeForce RTX 50 Open-Source Linux Performance For 2025
In the past few weeks on Phoronix we have explored a fresh look at the open-source Nouveau/NVK performance compared to the NVIDIA 580 packaged Linux driver as well as a multi-generation Nouveau vs. NVIDIA comparison from the GeForce GTX 980 to RTX 5080 since the forthcoming NVIDIA R590 driver series is ending the GTX 900/1000 series support. Today’s article provides another round of fresh open-source NVIDIA Linuc graphics performance data using the upstream open-source Nouveau and Mesa NVK/Zink drivers compared not only to the current NVIDIA packaged driver but also competitively for how the GeForce RTX 50 line-up compares to the current AMD Radeon RX 9000 series graphics cards.
Snapdragon X Elite Laptop Performance On Linux Ends 2025 Disappointing
As part of my various end-of-year benchmarking comparison articles for looking at the performance evolution of Linux is a fresh look at the Qualcomm Snapdragon X Elite laptop experience when using Ubuntu 25.10 with the latest X1E Concept packages, which includes taking the X1 Elite optimized kernel to the latest Linux 6.18 stable series. Unfortunately, there are significant performance regressions observed compared to a few months ago that just make AMD Ryzen AI and Intel Core Ultra laptops a better choice for Linux laptop users.
Unexpected Surprise: Windows 11 Outperforming Linux On An Intel Arrow Lake H Laptop
Typically when receiving any review hardware preloaded with Microsoft Windows I tend to run some Windows vs. Linux benchmarks just as a sanity test plus it still seems to generate a fair amount of interest even though the outcome is almost always the same: Linux having a hefty performance advantage over Windows especially in the more demanding creator-type workloads. As an unexpected twist and time consuming puzzle the past two months, when recently testing out the Lenovo ThinkPad P1 Gen 8 it’s faster for numerous workloads now on Microsoft Windows 11 than Ubuntu Linux.
The Performance Of Arch Linux Powered CachyOS On AMD EPYC Servers
One of the more interesting announcements over the holiday period thus far is that moving into 2026, CachyOS is looking to develop a server edition for their Arch Linux based operating system. CachyOS has garnered quite a following among Linux enthusiasts and gamers for its competitive out-of-the-box performance, employing some of the optimizations by Intel’s now defunct Clear Linux distribution, and pulling in all of the goodness from upstream Arch Linux. It will be very interesting to see how CachyOS Server Edition takes shape and whether it will develop a foothold in any prominent enterprise environments. While CachyOS Server Edition isn’t yet released and still in its early stages, over the holidays I decided to see how CachyOS in its current form currently looks for AMD EPYC servers.
Intel Arc B580 vs. AMD Radeon RX 9000 vs. NVIDIA RTX 50 Series For Llama.cpp Vulkan Performance
Recently there were Phoronix benchmarks looking at the Intel Battlemage GPU compute performance since last year when the Arc B580 graphics card launched as well as the OpenGL and Vulkan graphics performance for the B580 on Linux since launch. There was much progress on the open-source Intel Linux graphics drivers at large this year but especially for Battlemage. Following that a Phoronix Premium reader asked about seeing some fresh Llama.cpp AI benchmarks with its Vulkan back-end now for the Arc B580 compared to competing AMD and NVIDIA graphics cards. Here are those benchmarks as requested.
Intel Xeon 6980P vs. AMD EPYC 9755 128-Core Showdown With The Latest Linux Software For EOY2025
Since receiving the Gigabyte R284-A92-AAL1 a while back as a Xeon 6900 series 2U server platform to replace the failed Intel AvenueCity reference server, I have been getting caught-up in fresh Xeon 6980P Granite Rapids benchmarks with the latest software updates over the past year. I’ve provided fresh looks at the DDR5-6400 vs. MRDIMM-8800 performance, the AMX benefits for AI, SNC3 vs. HEX mode, Latency Optimized Mode, Cache Aware Scheduling, and more with the fresh Linux software stack and this production Gigabyte server platform. One of the areas I have been meaning to re-visit is a fresh head-to-head benchmark battle between 5th Gen AMD EPYC “Turin” and Intel Xeon 6 “Granite Rapids”. In this article is a 128-core showdown between the Xeon 6980P and EPYC 9755 128-core processors with the latest open-source Linux software as of the end of 2025.
NVIDIA GTX 980 Through RTX 5080: Open-Source Nouveau/Mesa Drivers vs. NVIDIA 580 Linux Drivers
With the NVIDIA 590 Linux driver series removing GeForce 900 series “Maxwell” and GeForce 10 series “Pascal” as part of punting it off to the latest legacy driver branch, it’s time for a last look at how the mainline NVIDIA Linux driver is performing with these aging graphics cards relative to the current state of the upstream open-source NVIDIA Linux drivers. In this article is a look at how the open-source and upstream Nouveau kernel driver with Nouveau/NVK Mesa drivers are performing relative to the NVIDIA 580 series with its Maxwell and Pascal support. For further perspective is also tossing in newer graphics cards too for providing a end-of-year GeForce 980 / 1080 / 2080 / 3080 / 4080 / 5080 series comparison between these different Linux drivers.
Final Benchmarks Of AMDVLK vs. RADV AMD Radeon Vulkan Drivers
One of the pleasant surprises this year was AMD ending the AMDVLK driver development with AMD dropping their proprietary OpenGL and Vulkan driver components on Linux at long last for their Radeon Software for Linux packages. This was arguably long overdue with enthusiasts and Linux gamers long preferring the RadeonSI+RADV Mesa drivers and those drivers even doing very well in recent years for workstation graphics workloads. One of the areas where AMDVLK formerly delivered better performance than RADV was with Vulkan ray-tracing. But RADV ray-tracing improved a lot in 2025 as shown in recent benchmarks. So for this Christmas 2025 benchmarking is a final look at how RADV is going up against the now-defunct AMDVLK driver.
