DragonFlyBSD lead developer Matthew Dillon has been working on a big VM rework in the name of performance and other kernel improvements recently. Here is a look at how those DragonFlyBSD 5.5-DEVELOPMENT improvements are paying off compared to DragonFlyBSD 5.4 as well as FreeBSD 12 and five Linux distribution releases. With Dillon using an AMD Ryzen Threadripper system, we used that too for this round of BSD vs. Linux performance benchmarks.
The Linux kernel will likely soon see a lot of old ISDN (Integrated Services Digital Network) subsystem/driver code deprecated and ultimately removed considering there aren't even many (or any in some places) ISDN public data networks...
As I've been saying for weeks now since the initial AMDGPU LLVM compiler back-end support was posted and based upon the release cadences for the various projects: AMD's next-gen "Navi" GPU support is likely to come with Linux 5.3 and Mesa 19.2. That's now been further firmed up and does appear AMD will be posting those kernel and Mesa/OpenGL driver changes in early to mid June for meeting those release windows...

It's been very fascinating to watch the speed improvements of Intel's SVT-AV1 open-source AV1 video encoder since in February when being made aware of Intel's new SVT video projects. The SVT-AV1 project is ending out May with another step-up in performance for what is already one of the fastest CPU-based AV1 video encoders...

While the Linux 5.2 kernel won't see its debut until July followed by the opening of the Linux 5.3 kernel cycle, the AMD developers sent in today their initial set of staged changes to DRM-Next for queuing their preliminary AMDGPU/AMDKFD driver changes they want to get into this next kernel cycle. There are some notable additions but what we are expecting/hoping for and haven't seen yet is the Navi support...
While Oracle has control of DTrace following their acquisition of Sun Microsystems, it turns out Oracle developers are quite interested in adding eBPF support to the GNU toolchain with GCC support as an alternative to the LLVM-focused path currently relied upon for targeting this in-kernel Linux virtual machine...

OpenSUSE/SUSE has always tended to perform well on AMD hardware given the close collaboration between the two companies for many years on numerous fronts going back to the original Linux AMD64 kernel upbringing to the RadeonHD driver days, compiler collaboration, and numerous other activities between SUSE and AMD. With last week's release of openSUSE Leap 15.1, the performance on AMD EPYC servers is even more competitive thanks to various upgrades.

Nearly a year ago we reported on the initial work done by Intel's Linux team on adding new CPU instructions for Tremont CPU cores, in particular the new UMWAIT instructions for enhancing power-savings during idle periods. That code continues to be revised for the UMWAIT kernel support but it has yet to be mainlined...
One of my personal biggest issues with using the GNOME Shell on Wayland has been the sluggish multi-monitor performance with driving dual 4K displays on my main workstation. Fortunately, GNOME is moving closer to resolving the fundamental issue and that could happen possibly with this current GNOME 3.34 cycle...
