One of the letdowns of the forthcoming Linux 5.6 kernel is that AMD's long-awaited Sensor Fusion Hub "SFH" open-source driver wasn't ready in time for merging this cycle, but it continues moving forward with hopes of seeing it in Linux 5.7...

RISC-V's Supervisor Binary Interface "SBI" is the interface between the platform-specific firmware and the running operating system or hypervisor for interacting with the supervisor execution environment in the higher privileged mode. The Linux kernel has been working to support a newer version of the SBI that is more extensible moving forward...

With the big Linux 5.6 kernel on the open-source NVIDIA "Nouveau" driver side there is finally accelerated support for the GeForce RTX 2000 "Turing" graphics cards (when paired with binary-only microcode). With that initial cut support is no GeForce 16 series Turing support, but that is now on-deck for Linux 5.7...

There is experimental work pending that plumbs support into MEMFD for creating "secret" memory areas. This secret memory support would then be exposed to user-space for different use-cases...

Wayland 1.18 is out today as the first update to the core Wayland code in nearly one year...

One of the interesting takeaways from my pre-launch briefing with AMD on the Ryzen Threadripper 3990X was AMD representatives actually recommending Clear Linux for use on this 64-core / 128-thread HEDT processor and the platform to which they've found the best performance. Yet, Clear Linux is an Intel open-source project. In any case, here are benchmarks of how Clear Linux performs against other Linux distributions on the Ryzen Threadripper 3990X within the System76 Thelio Major. And, holy crap, with the Threadripper 3990X on Clear Linux I managed to build the x86_64 default Linux kernel in under 20 seconds!

With the recently released Linux 5.5 and its new features, one of the prominent changes on the storage front was the Btrfs file-system picking up new "RAID1C3" and "RAID1C4" modes for allowing either three or four copies of RAID1 data across more drives to potentially allow up to three of four drives to fail in a RAID1 array while still being able to recover that data for this file-system with its native RAID capabilities...

Now that the merge window is over for Linux 5.6, where the Nouveau open-source NVIDIA driver managed GeForce RTX 2000 "Turing" series accelerated support, a new feature addition landed Monday in the Nouveau kernel development tree for the next cycle...

For those that may be looking to run an air-cooled AMD Ryzen 9 3950X especially in a rack-mount 4U chassis, here are some recent results I did from some testing using a Noctua NH-U9S with two 92mm fan configuration. Additionally, these results contain performance metrics from both CPUFreq Ondemand vs. Performance governors as an additional point of interest...

Red Hat's Karol Herbst who has spent years now working on Nouveau SPIR-V support and other GPU open-source compute efforts around Mesa has provided a trivial implementation of clCreateCommandQueueWithProperties() that is now enough to begin running the OpenCL 2.0 conformance test suite on the Gallium3D "Clover" state tracker...

Out this Sunday is OpenShot 2.5 as the non-linear video editor's biggest release yet for this cross-platform, open-source solution...

The Linux 5.6 merge window is anticipated to be ending today followed by the Linux 5.6-rc1 test release. This kernel is simply huge: there is so many new and improved features with this particular release that it's mind-boggling. I'm having difficulty remembering such a time a kernel release was so large.

One of the last features to land today for Linux 5.6 ahead of the merge window closure is Western Digital's Zonefs file-system...

For those using GNU Make in particular as their build system, the parallel build times are about to be a lot faster beginning with Linux 5.6 for large core count systems.
