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...

Intel's open-source Compute Runtime stack for OpenCL and oneAPI Level Zero on their graphics processors has been bringing up Nova Lake support since January. 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...

After Linux 7.1 dropped support for old i486 CPUs and also began removing some old ISA and PCMCIA device drivers, there is some additional old hardware relics being cleared out of the in-development Linux 7.2 driver... 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...

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...

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...

Following Friday's exciting release of Wine 11.11 with Wayland driver improvements, Wine-Staging 11.11 is now available for this experimental/testing derivative that continues carrying nearly 300 patches atop the upstream codebase...

Among Intel's ongoing reduction in open-source projects they maintain, their BigDL open-source project focused on running large language models across Intel XPUs from Core Ultra laptops to discrete GPUs to cloud / data center hardware all in a low-latency manner, is being ended...

Among the changes being considered for the in-development Fedora 45 is a lightened version of the GRUB UEFI bootloader that would focus on being a minimal implementation suitable for confidential computing...

Released on Friday was the newest version of Intel Thermald, the thermal daemon developed by Intel for their processors on Linux for monitoring and helping control temperatures across modern Intel-powered laptops and desktops. Catching me immediately by surprise was Intel Thermald 2.5.12 introducing support for ARM...

Earlier this month I wrote about Intel working on function multi-versioning support for APX and AVX10.2 with the GCC compiler. This allows developers to write optimized code paths specifically targeting Advanced Performance Extensions (APX) or Advanced Vector Extensions 10.2 capabilities of future processors while being able to otherwise fall-back to generic or other optimized code paths for other ISA target features. This work is now merged for GCC 17...

The BeOS-inspired Haiku open-source operating system now enables Advanced Vector Extensions 512 on capable Intel/AMD CPUs. A number of other hardware driver improvements were also merged for this interesting OS during the last month...

Ahead of the much anticipated Plasma 6.7 desktop release next week, KDE developers have been busy putting final touches on it, mostly in the form of bug/regression fixes...

Last year when releasing Red Hat Enterprise Linux 10.0, Red Hat announced a RHEL 10.0 developer preview for RISC-V. Since then that RISC-V developer preview hadn't been updated but now Red Hat has published a new developer preview snapshot based on RHEL 10.2...

Ever since AMD announced openSIL in early 2023 for open-source CPU silicon initialization to eventually replace AGESA and enhance their Coreboot support, I have been eager to try it out. The openSIL code drops to date though have just focused on select reference platforms with only aiming for production status in the Zen 6 timeframe. But thanks to 3mdeb porting openSIL and Coreboot to a Gigabyte server motherboard, it's now possible to try out openSIL+Coreboot right now on Zen 5 hardware.

On Sunday it's anticipated that Linus Torvalds will released the stable Linux 7.1 kernel. This is a really terrific mid-year update to the Linux kernel! Here's what makes me excited about Linux 7.1...

Among the many new features planned for Ubuntu 26.10 is switching the default D-Bus implementation over to using the high performance Dbus-Broker drop-in replacement...
