AMD RAPL PowerCap Patches Updated For Linux - Now Include Family 19h (Zen 3)

Patches from a Google engineer allow run-time average power limiting (RAPL) support for AMD Zen processors within the Linux PowerCap driver.

Earlier this year was AMD Zen RAPL support in the Perf subsystem while this more recent activity for AMD RAPL has been about the PowerCap code. The Linux PowerCap framework was originally conceived by Intel but AMD Zen CPUs have similar MSRs available for supporting limiting the CPU TDP and also reading the current energy usage. With these patches /sys/class/powercap/intel-rapl/intel-

GIMP 2.10.22 Released With AVIF Image Support

While GIMP 3.0 development drags on, the GIMP 2.10.x stable series continues seeing new and interesting point releases. Out today is GIMP 2.10.22 that now supports the AV1-based AVIF image format for import and export.

Exciting with the GIMP 2.10.22 point release is support for AVIF , the very promising image format based on royalty-free AV1 technology and that is already supported by web browsers like Firefox and Google Chrome while continuing

AMDGPU Linux Kernel Driver Support Posted For The "Dimgrey Cavefish"

At the end of September there were Mesa patches posted for the "Dimgrey Cavefish" at the same time as also posting VanGogh APU support for the RadeonSI Gallium3D driver. The AMDGPU Linux kernel driver support has now been posted for the Dimgrey Cavefish.

The Dimgrey Cavefish is another RDNA2 part alongside Sienna Cichlid and Navy Flounder.

Fifty patches were posted today amounting to four thousand lines of new code for wiring up the Dimgrey Cavefish in the direct rendering manager driver. A bulk of that new code is for DCN 3

DXVK 1.7.2 Released With Many Fixes For Direct3D Atop Vulkan

DXVK 1.7.2 was just released as this popular library for mapping Direct3D 9/10/11 atop the Vulkan API primarily for accelerating Windows games on Linux via the likes of Steam Play (Proton) and Wine.

DXVK 1.7.2 brings fixes for various Direct3D 9 crashes, workarounds for rendering issues with AMD drivers for some Unity games, support for disabling log files, and various game-specific fixes/improvements.

Game specific work for DXVK 1.7.

Blender 2.90 Performance With GeForce RTX 3080, 18-Way NVIDIA CUDA/OptiX Comparison

Complementing yesterday's large GPU compute comparison with the GeForce RTX 3080 across many different workloads, today's article is looking at the Blender 2.90 render performance for this consumer Ampere $699+ graphics card.

Like with the numbers shown yesterday, the GeForce RTX 3080 is a serious upgrade over the RTX 2000 Turing series and older generations. With this Blender 2.90 comparison and testing the CUDA and OptiX back-ends, the comparison GPUs

OpenZFS 2.0 Nears Release, OpenZFS 3.0 Could See macOS Support

The virtual OpenZFS Developer Summit got underway on Tuesday with many interesting talks on the open-source work around the ZFS file-system.

Kicking off the event was the state of OpenZFS by Matt Ahrens. You can see the slide deck as well as the video recording below. OpenZFS 2.0 continues shaping up well with the much talked about FreeBSD support mainlined earlier this year, Zstd compression support, many performance enhancements, redacted send/receive, Zpool wait, sequential resilvering, persistent L2ARC, and more.

A New Linux Kernel Framework To Help Ensure You Don't Burn Yourself On Hot Devices

Linaro is working on the DTPF framework for the Linux kernel for meeting legal requirements around the maximum allowed case/contact temperature of devices.

The Dynamic Thermal Power Management (DTPM) framework being worked on for the Linux kernel is a unified interface for dealing with the power of different devices -- namely for mobile hardware and related consumer devices. The DTPM kernel framework would then provide a generic interface to user-space where a daemon is taking into account any application profile(s) and allocating an appropriate power budget to different

Better Support For Newer Synaptics Laptop Touchpads Coming To Linux 5.10

Synaptics has contributed RMI4 F3A support for Linux 5.10 to better the support for newer laptop touchpads.

Synaptics' RMI4 Function 3A (F3A) is used by newer touchpads for GPIO support, this is needed to support buttons on TouchPads and Clickpads. Among the devices benefiting from the RMI4 F4A support are the likes of the Lenovo ThinkPad X1 Extreme Gen1 and P1 Gen2 laptops.

A Synaptics engineer contributed the F3A support and a follow up
