While still waiting on the ROCm 1.9 release to happen, version 1.8.3 of the Radeon Open Compute stack was released for Linux systems.
One of the most frequent test requests recently has been to look at the overall performance cost of Meltdown/Spectre mitigations on the latest Linux kernel and now with L1TF/Foreshadow work tossed into the mix. With the Linux 4.19 kernel that just kicked off development this month has been continued churn in the Spectre/Meltdown space, just not for x86_64 but also for POWER/s390/ARM where applicable. For getting an overall look at the performance impact of these mitigation techniques I tested three Intel Xeon systems and two AMD EPYC systems as well as a virtual machine on each side for seeing how the default Linux 4.19 kernel performance -- with relevant mitigations applied -- to that of an unmitigated kernel.

Announced last October was a 24-core ARM developer box being worked on by Linaro/96Boards, Socionext, and Gigabyte. The specifications are appealing with twenty-four ARM 64-bit cores with the SoC on a micro-ATX sized motherboard, support for a PCI Express graphics slot, and onboard Gigabit Ethernet. Here are our first benchmarks of this Socionext 96Boards Developerbox.

While .NET applications have been supported on Linux for a while now via the .NET Core, using performance profiling tools really haven't working out but that is now changing.
Word this week of the NVIDIA Jetson Xavier Development Kit being up for pre-order reminded me of some benchmarks I had been meaning to do of seeing how the NVIDIA Jetson TX2 developer kit's performance has evolved since its launch a year and a half ago. There's actually a quite measurable improvement in performance with the latest software/drivers compared to it was at launch.
For those looking at affordable metal server racks / open rack cabinets, I continue to be quite impressed by the StarTech.com four-post server racks. Recently I commissioned two more of their 12U racks in order to accommodate the latest Threadripper 2 systems in our Linux benchmarking farm.

The performance-optimized Clear Linux distribution out of Intel's Open-Source Technology Center started out with Xfce as its lone desktop option and then added and moved over to the GNOME Shell as the default desktop. While GNOME Shell remains the default desktop choice for this rolling-release Linux distribution, KDE components have begun appearing in recent days.
Linux firmware updating is on a roll with the fwupd updating utility and the Linux Vendor Firmware Service (LVFS) for the distribution of these firmware files recently seeing AKiTiO Thunderbolt device support and NVMe SSD firmware updating being the next big task. Richard Hughes of Red Hat has also revealed he's been working on USB3 hub firmware support in conjunction with Realtek.

As a P.S.A. for those tending to quickly upgrade to new major kernel releases but are doing so on older hardware, there appears to be a show-stopping bug that made it into the stable Linux 4.18 series.
Two years after Solaris 11.3 and Oracle opting for a "continuous delivery" model of 11.next updates instead of a "Solaris 12", Solaris 11.4 is out the door today.
One of the most interesting projects we've seen attempted for Google Summer of Code 2018 was adding Vulkan support to VirGL for allowing Vulkan access within guest virtual machines.
Last week NVIDIA released the 396.54 driver that has a significant performance fix for OpenGL/Vulkan Linux performance due to a resource leak regression introduced at the start of the 390 driver series. With that updated driver (also as of yesterday back-ported to 390.87 too), there is a measurable boost in performance after running a few games on NVIDIA Linux systems. But at the same time, the Mesa 18.3-dev open-source graphics driver stack with RadeonSI/RADV continues improving on the open-source AMD front. Here is a fresh look at how the latest AMD Radeon and NVIDIA GeForce graphics cards compare using these latest drivers.
Given Valve's now public Steam Play for Linux using the Wine-derived Proton and their ongoing relationship with Code Weavers to improve the experience for Windows games on Linux, it perhaps adds better context why this summer for GSoC there was the automated Direct3D game benchmarking work with mentorship by a CodeWeavers developer.
In addition to the VKMS driver for virtual kernel mode-setting, the other successful Google Summer of Code (GSoC) project this summer under the X.Org umbrella was improving the DRM GPU scheduler.
While the Linux 4.19 kernel merge window just ended this past weekend and the development cycle for Linux 4.20 (or most likely to be called Linux 5.0) won't kick off until around the middle of October, AMD has already begun staging a ton of changes for this next kernel version. In particular, it looks like with this next kernel release their Vega 20 enablement will be in order.
Ubuntu's Mir display server that has been chasing Wayland support and earlier this year introduced EGMDE as the example Mir desktop environment has picked up some extra functionality on its "edge" channel.
One of the features sadly not making it into the in-development Linux 4.19 kernel is the support for Intel's SGX -- the Software Guard Extensions.

With all of the confusion last week over Intel's short-lived CPU microcode license change that forbid benchmarking only for them to change it a short time later -- to a much nicer license in that the microcode files can be easily redistributed and don't curtail it in other manners (and also re-licensing their FSP too), here are some performance benchmarks when trying out this latest Intel microcode on Linux.
