For those reasons plus in preparing for the Raven Ridge testing, here are benchmarks of 19 different systems when using Ubuntu x86_64 with the Linux 4.15 stable kernel.
Open-source AMD Linux driver developers have started off the week by posting 34 more patches for the "DC" display code stack that was mainlined in Linux 4.15 and further improved with Linux 4.16. With these latest patches that begin the queue for Linux 4.17 there are yet more AMDGPU DC improvements and in particular Raven Ridge fixes...
Last week marked the inaugural release of Xorgproto, a new package consisting of all the X.Org protocol headers rather than being in standalone packages now that X.Org Server development is slowing down and that many of these protocol headers wind up getting updated at the same time. Today marks the Xorgproto 2018.2 release...
Wayland 1.15 and the Weston 4.0 compositor had been planned for release in February but Wayland developers decided there was still enough material on the verge of landing that they decided to delay the release.

A decade ago Linux users were clamoring for Sun Microsystems to bring Solaris' DTrace and ZFS to Linux. While there are still petitions for Oracle to more liberally license ZFS so it could see mainline Linux support, it's been years since hearing much interest in DTrace for Linux. Over time other dynamic tracing implementations have come about and improved in comparison to DTrace, but for those still wanting this dynamic tracing framework that originated at Sun Microsystems, Oracle remains working on the Linux port...

After the lengthy Linux 4.15 kernel cycle, the past two weeks have marked the Linux 4.16 merge window. Yet again it's been another heavy feature period for the kernel. There is still a lot of mitigation work going on for most CPU architectures surrounding Spectre and also Meltdown, the open-source graphics drivers have continued getting better, various CPU improvements are present, the VirtualBox Guest driver was mainlined, and dozens of other notable changes for Linux 4.16. Take a look.

The EOMA68 computer card project is the open-source hardware effort that aims to be Earth-friendly and allow for interchangeable computer cards that can be installed in laptop housings and other devices. The ambitious concept relying upon ARM SoCs raised more than $170k USD via crowdfunding in 2016 but its lineage dates back to the failed Improv dev board as well as the failed KDE Vivaldi tablet years earlier. It turns out in 2018 there is hope of EOMA68 hardware finally shipping...
