KDE developer Nate Graham is out with his usual weekly development recap of all the interesting Plasma desktop changes to have landed over the past week.

Last week I published some initial benchmarks of the Amazon/AWS Graviton4 processors now available within the EC2 cloud using the new "R8g" instances. That initial comparison was a 64 vCPU comparison of Graviton4 against AMD EPYC and Intel Xeon 64 vCPU AWS instances. In today's article is a look at the 96-core Graviton4 bare metal performance using the "r8g.metal-24xl" AWS instance type. The Graviton4 r8g.metal-24xl performance was then compared in today's article against various bare metal AMD EPYC, Ampere Altra Max, and Intel Xeon processors in the lab at Phoronix.

While the Bcachefs feature changes for Linux 6.13 were already submitted even before the Linux 6.12 stable kernel was released, merging these changes are supposedly on hold due to the kernel's Code of Conduct (CoC) board.

Linux 6.13 has merged support for the Secure Digital Ultra Capacity "SDUC" standard for 2TB to 128TB storage capacity SD cards.

Andrew Morton on Monday submitted all the memory management "MM" related patches for the Linux 6.13 merge window. As usual there's a lot of interesting performance optimizations and other low-level refinements.

The abundance of networking subsystem updates have been mailed in for the Linux 6.13 kernel from wired and wireless driver enhancements to core networking code improvements.

As I wrote about last week within the Supermicro H13SSL-N EPYC Turin motherboard review, one of the factors leading me to purchasing that EPYC 9005 series motherboard was that this board offered support for full 12 channel DDR5-6000 memory performance compared to some of the other lower-cost Socket SP5 motherboards offering just 8 memory channels. For those wanting to quantify the performance difference between eight and twelve memory channels with AMD EPYC 9005 "Turin" processors, here are some benchmarks for showing the workloads that can really benefit from all 12 memory channels and other workloads where eight memory channels can be largely sufficient if looking to minimize costs.

Following the initial Raspberry Pi 5 upstream support in Linux 6.12 providing basic support, an exciting Raspberry Pi addition with the in-development Linux 6.13 kernel is introducing a Raspberry Pi Camera Front-End "CFE" driver.

The in-development Linux 6.13 kernel is bringing a lot of exciting improvements for AMD Linux customers.

Intel's open-source software developers released today OpenVINO 2024.5 as the newest major feature release for this cross-platform AI toolkit.

The crypto subsystem updates were merged yesterday for the in-development Linux 6.13 kernel. Among other crypto improvements are new optimizations for some algorithms when running on Intel and AMD x86_64 processors.

Merged last year for Linux 6.6 was multi-grain(ed) timestamps to address the current coarse-grained timestamps when updating creation time and modification time that a lot of I/O activity can happen in the once-per-jiffy timestamp. Just a few weeks in the Linux 6.6 kernel, multi-grain timestamps were removed due to bugs. The multigrain code went back to be reworked and now just over one year later the code has been re-merged into the mainline Linux kernel.

The HID subsystem updates have been submitted for the Linux 6.13 kernel cycle.

All of the scheduler feature changes were merged today for the Linux 6.13 kernel, including the introduction of the lazy preemption model.

FLTK 1.4 is out as the newest version of the Fast Light Toolkit that has been around since the late 90's.

While most users frown upon the increasing number of CPU security mitigations in part due to the additional overhead commonly introduced, a new Linux kernel patch by a Google engineer would allow users/developers to opt-in to forcing CPU bugs and their mitigations even if the system in use isn't known to be vulnerable.

Blender 4.3 is out today as the newest feature update to this leading open-source 3D modeling software.

FreeCAD 1.0 was just released as a major update to this leading open-source, cross-platform 3D parametric modeler software.

The power management subsystem updates have been submitted for the newly opened Linux 6.13 merge window. As covered within individual articles over the past few weeks, the Linux 6.13 power management updates include some notable changes for both AMD and Intel systems.
