Linux 6.19 Adds New Console Font To Better Handle Modern Laptops With HiDPI Displays
6 December 2025 - Terminus 10x18 Console Font

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.

Rust Drivers In Linux 6.19 Will Now Support... Module Parameters
7 December 2025 - Rust Module Parameters

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.

NVIDIA Plumbs DMA-BUF Support For VFIO PCI Devices In Linux 6.19
7 December 2025 - DMA-BUF For VFIO PCI

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.

Linux 6.19 Introduces PCIe Link Encryption & Device Authentication, AMD SEV-TIO Enabling
7 December 2025 - PCI Express Link Encryption

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.

Early Benchmarks Of Linux 6.19 Git Raising Some Concerns
8 December 2025 - Linux 6.19

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.

Live Update Orchestrator "LUO" Merged For Linux 6.19
8 December 2025 - Live Update Orchestrator

Google engineers for the past number of months have been working on the Live Update Orchestrator as a new way of applying live Linux kernel updates. The Live Update Orchestrator "LUO" builds atop the Kexec Handover "KHO" functionality already within the kernel. Google has since been deplyoing LUO in their production environments for faster security updates to kernels, especially when involving VMs. LUO is now upstream in Linux 6.19.

Linux 6.19's Hung Task & System Lockup Detectors Can Provide Greater Insight
8 December 2025 - More Dumping

Beginning with the Linux 6.19 kernel, the hung task detector and system lock-up detector are now optionally able to provide greater insight into the issues by dumping additional system information. The new lockup_sys_info and hung_task_sys_info sysctl knobs were merged over as part of the pull requests managed by Andrew Morton.

Bug-Catching "Smatch" Static Analysis On The Linux Kernel Under Threat Due To Funding Gap
9 December 2025 - Smatch Static Analysis

For the past 15 years the Smatch static analysis tool has been routinely run for uncovering countless bugs within the Linux kernel. Dan Carpenter who authored Smatch and has been routinely analyzing the Linux kernel with it has authored more than 5,568 patches over the years to become one of the top bug fixers for the kernel. But his funding at Linaro has been cut and the project's future now in question.

Linux 6.19 Gets Rid Of The Kernel's "Genocide" Function
10 December 2025 - d_genocide

While the Linux kernel has inclusive terminology guidelines for the past five years to replace phrases like master/slave and blacklist/whitelist, there has surprisingly been a "genocide" function within the kernel that was questioned when it was first submitted for inclusion but now removed in Linux 6.19.
