While just half-way through the Linux 6.19 merge window, over the weekend I began running some benchmarks of the current Linux 6.19 Git state compared to Linux 6.18 LTS stable. There are some minor performance improvements to note in a few of the tests on the first system I tested but also some regressions at this very early pre-RC1 state of the Linux 6.19 kernel...

One of the new Linux engineering initiatives out of AMD is working to further enhance Linux performance on today's large core count systems by introducing push-based load balancing...

All of the Human Interface Devices (HID) subsystem updates were merged a few days ago for the ongoing Linux 6.19 kernel merge window. Standing out this cycle on the HID side are seeing new/improved support for several Logitech devices...

I2C in Linux 6.19 brought support for Rust-written I2C drivers. The newer I3C "Improved Inter-Integrated Circuit" interface changes have now been merged and the big feature there is HDR support. Not to be confused with the more common High Dynamic Range acronym usage for HDR, HDR in the I3C context is for the "High Data Rate" mode for facilitating faster data transfers...

The ARM64 code changes were merged last week into the in-development Linux 6.19 kernel. The most notable of the ARM64 architecture changes this cycle is landing the Arm MPAM driver for Arm's Memory System Resource Partitioning and Monitoring...

Released today is a new version of Iced, the popular cross-platform GUI library for the Rust programming language. Iced is notably used by the COSMIC desktop environment and a growing variety of different Rust apps...

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...

One of the most exciting merges this weekend to the Linux 6.19 kernel is establishing the infrastructure for supporting PCI Express link encryption and device authentication. Multiple vendors are working on PCIe link encryption for their hardware while this initial pull begins laying the foundation of AMD SEV-TIO Trusted I/O support for the mainline kernel...

Merged last night for the Linux 6.19 kernel merge window were all of the USB and Thunderbolt driver changes. Standing out this cycle is Apple Silicon devices like the M1 Macs now having working USB3 support on the mainline Linux kernel...

In addition to NVIDIA improving peer-to-peer (P2P) DMA for block devices in Linux 6.19, NVIDIA also led an effort providing DMA-BUF support for VFIO PCI devices for opening up some interesting new cases moving forward. As part of the VFIO pull request this new functionality has landed for Linux 6.19...

A week ago I wrote about AI being used to help modernize Ubuntu's Error Tracker. Microsoft GitHub Copilot was tasked to help adapt its Cassandra database usage to modern standards. It's worked in some areas but even for a rather straight forward task, some of the generated functions ended up being "plain wrong" according to the developer involved...

On top of the Rust driver core changes and other Rust code for Linux 6.19, the modules infrastructure for this new kernel version is also bringing some new code. Surprisingly, it's taken until now for Rust kernel modules/drivers to support module parameters as is common practice for passing different options when booting the kernel or manually loading kernel drivers with extra non-default options...

Sent in for the Linux 6.19 merge window when it comes to the frame-buffer device "FBDEV" subsystem are just a set of "fixes" for FBDEV drivers and code clean-ups. But it does also include a new console font option for better supporting modern laptops with high density displays...

The Non-Volatile Memory Device (NVDIMM) subsystem updates were merged today for the in-development Linux 6.19 kernel. Most notable this cycle for the NVDIMM code is a new open-source driver addition courtesy of Microsoft...

Making for a bit more exciting weekend is that minutes ago AMD has posted their first patch for enabling Zen 6 processor support within the GNU Compiler Collection (GCC) for -march=znver6 targeting...

The latest improvement to the RadeonSI Gallium3D driver by prominent AMD Mesa developer Marek Olšák is enabling support for up to 64K x 64K textures with RDNA4 GPUs...

The set of six branches containing SoC and platform updates/additions for the Linux 6.19 kernel have been merged for enabling a lot of new RISC-V and ARM 64-bit hardware as well as enhancing some existing SoCs/platforms...

FEX 2512 is out today as the newest monthly update for this software that enables running x86/x86_64 Linux binaries on ARM64 Linux, including the likes of Wine and Valve's Steam Play (Proton) for being able to run Windows games on 64-bit ARM Linux devices...

Flowblade 2.24 released today as the newest version of this open-source, non-linear video editing application. Flowblade 2.24 brings a number of refinements while also interesting is their commentary concerning the future with Wayland and GTK4 porting...

For anyone still relying on Solaris in production or just nostalgic Solaris users from the grand Sun Microsystems days, Solaris 11.4 SRU 87 was released by Oracle this week as one of the heavier stable release updates in recent memory...
