With the GCC 9 compiler due to be officially released as stable in the next month or two, we've been running benchmarks of this near-final state to the GNU Compiler Collection on a diverse range of processors. In recent weeks that has included extensive compiler benchmarks on a dozen x86_64 systems, POWER9 compiler testing on the Talos II, and also the AArch64 compiler performance on recent releases of GCC and LLVM Clang. In this latest installment of our GCC 9 compiler benchmarking is an extensive look at the AMD EPYC Znver1 performance on various releases of the GCC compiler as well as looking at various optimization levels under this new compiler on the Znver1 processor.

That NIR-ified version of Gallium Nine is now working and beginning to run most Direct3D 9 games fine.
The GNOME project has been working on integration with the Matrix federated real-time communication protocol for a while, which can bridge to other platforms like IRC, WhatsApp, XMPP, and Telegram. KDE is also now backing Matrix and will be supporting it by its instant messaging framework.

While I am a big fan of Intel's Clear Linux distribution for its raw performance on x86_64 hardware that for most workloads goes unsurpassed by any other Linux platform out-of-the-box, there has been a lot of Phoronix readers wondering how well it could function as a standard desktop Linux distribution. With upgrading my main production system earlier this month, I decided to try out Clear Linux and now with 200+ hours into using it as the OS on my main production system, I figured it'd be good to share my initial thoughts.
One of the recent XFS innovations under work and maturing with time has been Copy on Write (CoW) support for this mature Linux file-systems. The XFS CoW support continues to be improved upon and an "always CoW" option is being prepared to always force this behavior.

Since November we haven't heard much about Google's effort around FS-VERITY as transparent integrity / authenticity support for read-only files on a writable file-system. Fortunately, the effort didn't stop and new patches are pending for this implementation that complements DM-VERITY.
Ubuntu 17.10 dropped its i386 / 32-bit x86 installer image while the i386 port has remained part of the package archive. Other Ubuntu derivatives over the past year have also moved to drop their 32-bit installer images and with Lubuntu/Xubuntu now ending their ISOs for that port, it's hitting the end of the road. Now for Ubuntu 20.04 LTS, there might not even be the i386 port.

The plan to use the Wayland-native version of Firefox by default for Fedora Workstation 30 atop GNOME has been tentatively approved by the Fedora Engineering and Steering Committee (FESCo).
Our past tests have shown that while most Linux distributions default to "none" for their I/O scheduler on NVMe solid-state storage, that isn't necessarily the best scheduler decision in all cases. Here are tests using the Linux 5.0 Git kernel using laptop and desktop hardware while evaluating no I/O scheduler, mq-deadline, Kyber, and BFQ scheduler options.
While we have talked about the possibilities of writing a Vulkan Wayland compositor and there was even a short-lived Vulkan renderer for KDE's KWin, it's also possible to write a X11 window manager around the Vulkan interfaces.

Intel now has released SVT-VP9 as a speedy open-source VP9 video encoder.
For those that have been wanting to try out the near-final Sway 1.0, this Wayland compositor has made its way into the Debian archive albeit only in the "experimental" section for now.
If you are in the market for an AMD Ryzen Threadripper or AMD EPYC heatsink that fits within 4U height requirements, the Noctua NH-U9 TR4-SP3 is still easily the best option available. I'm now running the NH-U9 TR4-SP3 in five different EPYC/Threadripper systems in the racks and they work out splendid.
