Added to the mainline Linux kernel last year was a Aquacomputer HWMON driver for initially supporting the German company's water-cooling pump under Linux with access to the fan speed, power, voltage, current, and coolant temperature. Since then that open-source driver developed by the community has been extended to cover an Aquacomputer fan controller and different models. For the Linux 6.1 cycle coming up there are more additions to the Aquacomputer driver...

Last week Laminar Research promoted X-Plane 12 to its early access public beta phase. This realistic flight simulator continues to natively support Linux -- and doing so well for many years -- and now with X-Plane 12, the Vulkan steps up past their long-used OpenGL renderer...

As part of the multi-year effort to overhaul the Linux kernel's printk() code there has been much work in recent months around threaded console printing so each registered console would have a kernel thread and console printing would be decoupled from the printk() callers. That work was aimed for Linux 5.19 but then reverted due to troubles. There is now a new implementation in the works...

The oneVPL Video Processing Library supports CPU-based execution as well as native Intel GPU acceleration for their latest Gen12/Xe hardware with a focus on Arc Graphics / DG2 hardware, targeting the Intel Media SDK for their older GPUs, and can be adapted for other possible back-ends...

Canonical used to host a stellar in-person event each Ubuntu Linux development cycle with the Ubuntu Developer Summit. That was over a decade ago and then it became largely a virtual event and then faded away in favor of Canonical's internal road-map planning and other developer sprints among their employees. Coming up in November in Prague is the return of an in-person official event with the Ubuntu Summit...

AMD engineers are working to better optimize the Linux kernel's scheduler for split-LLC (last level cache) processor designs, namely to benefit their EPYC server processors...

Sent out as a "request for comments" on Friday night was a new patch series out of Intel introducing the notion of "classes of tasks" for the Linux kernel so that the scheduler can make better decisions on hybrid processors like with Intel's Alder Lake processors and upcoming Raptor Lake. This also provides a more complete implementation of Intel Thread Director for Linux and may also be used as the basis for instruction set differences between the performance and efficient cores...

Intel engineers have submitted another batch of "i915" kernel graphics driver changes intended for Linux 6.1 that include updated GuC firmware version handling, more DG2/Alchemist Arc Graphics work, and also more Meteor Lake "MTL" enablement for that successor to Raptor Lake...

Fedora Linux releases whether they be development/beta snapshots or the stable releases are known for slipping all too often. Fedora will often delay due to blocker bugs as they aim to deliver a bleeding-edge yet reliable Linux distribution and thus a week or two delay here and there isn't uncommon at all. While they have been delivering more timely releases than in the past with their notorious delays, for Fedora Linux 37 Beta they have delivered on the feat of an on-time release...

Today they have now introduced AMD P-State EPP as they aim to deliver better performance-per-Watt...

VMware's performance engineering team today announced a performance regression in Linux 5.19 affecting compute performance up to -70%, networking up to -30%, and storage up to -13%.

For the past two decades Red Hat has been behind Sourceware.org for providing hosting for open-source projects like Cygwin, GNU GCC, GDB, Glibc, and many other projects. While Red Hat continues to sponsor the hosting and having their employees be involved with the Sourceware.org maintenance, etc, for ensuring a secured future they have been looking to hookup with the Software Freedom Conservancy (SFC). The SFC has now voted in favor of accepting this long-time open-source hosting service into their umbrella...

With yesterday's release of Blender 3.3 much of the excitement has been about the new Intel oneAPI back-end for Arc Graphics acceleration and also improvements to AMD's HIP back-end for supporting GPUs back to Vega. However, even if you are using CPU-based rendering, Blender 3.3 LTS is looking like a nice upgrade for better performance...

AMD's GPUOpen group has released an updated version of FidelityFX Super Resolution 2. The new FSR 2.1 brings quality enhancements and a reduction in artifacts as the primary benefits over the original FSR2 that was unvelied earlier this year and open-sourced during the summer...

With the AMD Ryzen 7 5800X3D as the first consumer processor with AMD 3D V-Cache technology that launched earlier this year, the Linux performance has been fantastic for a variety of workloads especially in areas of technical computing and other non-gaming workloads -- similar to the great results we've enjoyed with AMD EPYC Milan-X processors too. One of the areas I hadn't had a chance to look at until recently was how the Windows 11 vs. Linux performance is looking for this Ryzen CPU with its 96MB L3 cache. Here are those quick benchmarks.

Blender 3.3 is set to be released today and one of the exciting enhancements with this open-source, cross-platform 3D modeling software update is initial support for Intel oneAPI/SYCL GPU acceleration. Intel Arc Graphics discrete GPUs can now enjoy this accelerated Cycles back-end, permitting your driver stack is new enough on Windows or Linux and are using their new dGPUs and not existing integrated graphics. But this is just the start of their oneAPI GPU-accelerated push for Blender...

Since Apple introduced the M1 two years ago as their in-house Apple Silicon for laptops and desktops with a powerful AArch64 processor and custom-designed graphics processor, there has been much speculation about whether the Apple M1 (and now M2) graphics are a clean-sheet Apple design or derived from Imagination PowerVR graphics that Apple had been using with earlier SoCs. There has been some similarities brought up before with the Asahi Linux team working on enabling the Apple M1/M2 under Linux while the latest Mesa driver activity points to more common bits between PowerVR graphics hardware and the Apple AGX graphics...
