The char/misc changes with each succeeding kernel release seem to have less changes to the character device subsystem itself and more just a random collection of changes not fitting in other subsystems / pull requests. With Linux 5.3 comes another smothering of different changes...

While newer Linux distributions have run into problems on the new AMD Zen 2 desktop CPUs (fixed by a systemd patch or fundamentally by a BIOS update) and DragonFlyBSD needed a separate boot fix, FreeBSD 12.0 installed out-of-the-box fine on the AMD Ryzen 9 3900X test system with ASUS ROG CROSSHAIR VIII HERO WiFi motherboard.

For those using the NVIDIA proprietary graphics driver on an IBM POWER system, it could be a while before seeing Linux 5.3+ kernel support. Upstream has removed code depended upon by the NVIDIA binary driver for supporting the POWER architecture and as is the case they don't care that it will break NVIDIA driver support since it's binary/out-of-tree...

Nearly three years after OpenHMD 0.2, the OpenHMD 0.3 release is now available for the open-source SDK and support for various AR/VR headsets...

Today marks the immediate availability of KDE Frameworks 5.60...

Back in April I wrote about Coreboot seeing AMD Picasso APU enablement work as the first Zen/Ryzen processor target being handled by this open-source BIOS alternative. It now looks like that Picasso support is all squared away and ready for use by future AMD-powered Google Chromebooks...

While there is another nineteen years to go until the Year 2038 problem manifests, the GNU C Library "glibc" is one of the key software components still needing some fixes for this issue where this problem where storing the Unix time as a 32-bit signed integer will wrap around and become a negative number...

Simon Ser who has been serving as the Wayland/Weston release manager has laid out a schedule for getting out the next major release of Wayland's reference compositor...

While not too eventful on the end-user feature front, the XFS file-system has seen another round of clean-ups with the ongoing Linux 5.3 merge window...

Purism has shared their July update on their Librem 5 Linux smartphone progress, which is mostly focused around inching along their software support but without any update on their hardware or final design. While their latest public information has continued to report a "Q3" ship date, that's looking increasingly unlikely...

AMD has just alerted us that they have released a BIOS fix to their motherboard partners that takes care of the issue around booting newer Linux distributions on the new Zen 2 processors...

It's been (and still is) a particularly busy few weeks for benchmarking. For those curious about the Raspberry Pi 4 performance that was announced at the end of June along with Raspbian 10, here are our initial performance benchmarks of the Raspberry Pi 4 Model B in 2GB and 4GB variants compared to various other ARM SBCs.

Collabora's Pekka Paalanen landed another optimization this week into GNOME's Mutter for further enhancing the performance of using DisplayLink hardware and similar secondary GPUs under this Linux desktop...

F2FS is already very fast compared to the long-standing Linux file-systems when benchmarking on solid-state drives while for Linux 5.3 this file-system is getting in even better shape...

With the growing number of devices requiring loadable firmware/microcode at run-time and Linux continuing to simply support a lot more hardware, the size of /lib/firmware has ballooned in recent years while now for the upcoming Linux 5.3 kernel release is the ability to compress these firmware files for fairly significant space savings...

An Intel open-source developer contributed support to Wayland's reference Weston compositor for enabling HDCP support on a per-output basis using a new allow_hdcp option...

While just being a few days into the two-week long merge window for Linux 5.3, it's certainly another busy cycle even when considering the summer months tend to be a bit slower for developers...

One of the areas that I always have "fun" benchmarking for new CPU launches is looking at the compiler performance. Following the recent Ryzen 3000 series launch I carried out some initial benchmarks looking at the current Zen 2 performance using the newest GCC 9 stable series with its "znver2" optimizations. Here is a look at how the Znver2 optimizations work out when running some benchmarks on the optimized binaries with a Ryzen 9 3900X running Ubuntu 18.04 LTS.

AMD's GPUOpen group has released a new version of their GPU Performance API (GPA) with Navi support...

While currently Ubuntu makes use of GNOME Software as their "software center" (or "app store") with Snap integration, as we wrote about recently Canonical has begun writing their own Snap Store. Given this and that they don't plan to use GNOME Software in Ubuntu 20.04 LTS and thus have taken their developers away from working on the upstream support, GNOME developers are planning to disable the Snap plug-in for GNOME Software...

The recent work on enabling "-Wimplicit-fallthrough" behavior for the Linux kernel has culminated in Linux 5.3 with actually being able to universally enable this compiler feature...

The scheduler changes for the Linux 5.3 kernel are as busy as ever...

Microsoft's exFAT file-system is more than one decade old and while there has been out-of-tree efforts, the mainline Linux kernel as of yet does not support the file-system even with it appearing on more SD cards and other devices. But there is now a renewed effort to get an exFAT driver into the Linux kernel...
