A bug in the AMDGPU Linux kernel graphics driver leading to some laptop displays freezing after periods of use may finally be close to being resolved. Given the length and quantity of bug reports and one of the problematic commits being tracked back to 2017, it's a heavy hitting issue for some Linux users.

RDNA4 refresh? Or a lot of signals have pointed to GFX125x being possible AI/HPC accelerators such as for the upcoming Instinct MI400 series. Adding to the intrigue is GFX1251 being an APU. The latest LLVM compiler activity is further pointing to GFX1250/GFX1251 being for enterprise hardware.

The Error Detection And Correction (EDAC) drivers, such as for dealing with ECC memory error reporting, are heavy on the Intel side with Linux 7.2 in preparing for upcoming hardware.

There are a number of time(r) core subsystem changes for the Linux 7.2 kernel to better harden the kernel.

The ongoing rise in AI/LLM-generated patches hitting the mailing lists and affecting development workflows continues to impact Linux kernel development. For the ARM64 architecture updates in Linux 7.2 is an interesting anecdote over over feeling like this activity has "slowed us down a little on the feature side" and having to deal with this AI/LLM patch activity resulted in some features now being postponed from making it for this current Linux kernel development cycle.

Kent Overstreet announced the release today of Bcachefs-Tools 1.38.6 as the user-space tools built around the Bcachefs copy-on-write file-system. There are a few new features and a lot of performance work in v1.38.6 without bringing any on-disk format breakage.

The original DisplayLink USB display adapters were great for working with an upstream, open-source driver while sadly the newer DisplayLink tech has been limited to an out-of-tree driver and proprietary user-space daemon. But posted today is an experimental "Vino" driver that is a clean-room, reverse-engineered driver for newer DisplayLink hardware.

Epic Games announced today they have created a new version control system that is now open-source as Lore. Given the proliferation and excellence of Git, you may be wondering why Epic Games is pursuing another VCS option... They are specifically catering Lore to games and entertainment purposes with large file sizes.

Earlier this month plans were shared publicly of Ubuntu 26.10 aiming to build a context-aware desktop with local AI features and one of the first capabilities to be integrated speech-to-text support. Now we have more details on the speech-to-text plans with Canonical announcing the Myna project.

Linux 7.2 continues seeing a fair amount of storage-related changes from file-systems to the block device code itself, software RAID, the wonderful IO_uring interface, and more. Here is some of the latest feature work that has been merged for Linux 7.2.

Since the release in May of Firefox 151, Mozilla has been relying on the zlib-rs library for Gzip compression/decompression. This subtle change to use this Rust-based Zlib implementation has yielded some performance benefits and better memory safety but also some headaches when dealing with Intel CPU bugs.

There is no shortage of different file-systems available for Linux. New file-systems continue to come about in the open-source world but ultimately many of them end up not being well maintained or having very limited users and not necessarily innovating enough to make them worthwhile over other alternatives. Given the continued increase in file-systems looking to get into the Linux kernel, such as FTRFS and VMUFAT being some of the most recent and then even having multiple NTFS drivers for Linux, there is now documentation in place to formally lay out criteria for new file-systems to be accepted.

It's been a while since there has been any Slackware news to pass along, but this week they've finally landed the KDE Plasma 6 desktop in this legendary Linux distribution.

With today's release of the Intel Compute Runtime 26.22.38646.4, the Nova Lake Xe3P support has matured to the state of it being advertised now as under an "early support" status.

A patch series merged for the Linux 7.2 kernel addresses a race condition that can occur when a container is exiting yielding "VFS: Busy inodes after unmount" messages and a possible user-after-free condition. But the patch series also goes further and delivers a very nice optimization to lower the container unmounting latency for environments with heavy I/O load.

Merged as part of the many VFS changes for Linux 7.2 is the new OPENAT2_REGULAR flag for the openat2 system call. This can be used to limit programs to only open regular file-systems and avoid accidentally or intentionally opening up device files or other non-conventional data files on the file-system.

The frame-buffer device driver for the old Hercules Monochrome ISA graphics card is now removed from the Linux kernel after decades at play.

In addition to the surprising impact of /proc/filesystems read optimizations for Linux 7.2, another one of the VFS pull requests for this next kernel version is delivering some nice improvements for EXT4 and XFS around IOmap, the framework that maps file data offsets in memory to their physical locations on storage.

After some last minute delays pushing the 15.1-RELEASE back by two weeks, FreeBSD 15.1 is now shipping as the newest stable release of this BSD operating system.

After days of dealing with 1,500+ packages in the Arch Linux AUR containing malware, the latest headache in the Arch Linux User Repository is Russian spam and offensive messages.

The Firefox 152.0 release binaries are now available ahead of tomorrow's official unveiling. With Firefox 152 there is now the JPEG-XL support code being compiled by default for the release albeit still disabled at run-time by default behind a preference for now.

Reading /proc/filesystems for obtaining a list of file-systems supported by the running kernel is done frequently on Linux. Namely due to being read by the SELinux library (libselinux), reading of /proc/filesystems is done more often than one would typically expect and now the Linux 7.2 kernel is optimizing for it to yield much better performance.

While we have seen Coreboot work-in-progress support for older Ryzen-powered Framework Laptops, it seems there is a recent uptick in development around supporting Coreboot on Framework Computer's modern Intel-powered wares.

The scheduler updates were merged this morning for the Linux 7.2 kernel and it's exciting. Cache Aware Scheduling has finally been merged! This is a win for especially modern Intel and AMD processors with multiple last level caches (LLCs).

Miguel Ojeda already mailed in the many Rust code changes for the in-development Linux 7.2 kernel. This is quite a big Rust code with more than forty thousand new lines of Rust code in the kernel.

Newly-merged code for the in-development Linux 7.2 kernel will now expose the case-folding (case insensitive) behavior of local file-systems so that Linux file servers and others can properly report the actual behavior rather than guessing if case-folding is actually used/supported.

Following yesterday's release of the upstream Linux 7.1 kernel release, GNU Linux-libre 7.1 is out with its new build for de-blobbing various drivers from loading non-free-software microcode/firmware and other sanitizing of the kernel code in the name of software freedom.

Just a day after Arch Linux developers believed they got their malware AUR incident under control with 1,500+ packages affected by malware, another round of of AUR malware is now being discovered. This latest round is more sophisticated as with code obfuscation to better conceal the intent.

A few days back I wrote about Google's Eric Biggers spearheading an AVX-512 implementation of xor_gen() as the Linux kernel function used for generating and validating parity blocks such as for RAID5/RAID6. That initial implementation was yielding up to 41% better performance while a new implementation has now been posted for scoring some additional victories.

Open-source developer Matthias Klumpp wrote a blog post today outlining his recent work developing pkgcli, a new and modern command-line interface (CLI) around the PackageKit package management abstraction layer.
