For the past months we've been aware of CodeWeavers/Wine developers exploring a possible Vulkan back-end to WineD3D as an alternative to their long-standing approach of taking Direct3D calls and mapping it to OpenGL. This WineD3D Vulkan back-end would be akin to DXVK, VK9, D9VK, and others of ultimately using Vulkan to accelerate an alternative API. While the code has just been started, it appears the upstream Wine developers believe in their approach...

An updated firmware configuration should help some GeForce GTX 1000 "Pascal" users with their limited open-source driver support, but the situation remains a mess. Besides the fact of being binary blobs, it's more complicated this time around with the interfaces changing for what is expected by the Nouveau DRM kernel driver...

With next-generation EPYC processors expected to be released next quarter, it's a good time to see how the performance of the original EPYC 7601 32-core / 64-thread processor's performance has evolved on Linux since its 2017 launch. This article is looking at the performance of an AMD EPYC 7601 Tyan server when running Ubuntu 17.04 as the newest stable Ubuntu release when EPYC was originally introduced in June 2017 compared to the performance when running the new Ubuntu 19.04 as well as jumping ahead to running the in-development Linux 5.2 kernel release. Additionally, the Ubuntu 19.04 + Linux 5.2 kernel configuration when also disabling Spectre mitigations.

Here are benchmarks of five such drives, four of which are SATA 3.0 SSDs and even one NVMe SSD. There are also comparison points to more premium SSD products.

The newest feature arriving in Mesa 19.2 is the long in development EGL platform device code worked on by Emil Velikov...

Up to now the GNOME desktop has offered mouse accessibility support using the long-standing Mousetweaks program that allows for different actions to take place all from the lone input device for those that may be limited to manipulating only one button or other limitations around this primary input device. But GNOME's Mousetweaks only works with X11 so now Mutter has picked up mouse accessibility support itself that works on both X11 and Wayland sessions...

With recently seeing a deal on the Intel Core i5 9400F processor, I picked it up for testing as part of our Spectre / Meltdown / Foreshadow / Zombieload testing since it features some hardware mitigations and is otherwise quite similar to the unmitigated Core i5 8400 that I also have in the benchmarking farm. Here are some results when benchmarking the Core i5 8400 and Core i5 9400F with and without the current Linux mitigations for these CPU vulnerabilities.

For those still running decade and a half old ATI Radeon graphics hardware like the Radeon Xpress 200M found in numerous notebooks back in the day, a performance regression in the R300 Gallium3D driver is being sorted out after concerned users on this vintage hardware began bisecting and testing patches for a regression to this old ATI open-source driver that appears to have been adversely affected back in 2017...

While Bzip2 compression is still widely used by Linux systems, it hasn't seen an official update since 2010 and has rather stagnated as different Linux distributions have resorted to carrying their own patches and other maintenance work on this long used data compression tool. But now there is a new maintainer looking to take Bzip2 into the next decade...

When it comes to HDR display support on Linux we've seen a lot of infrastructure work being pursued by the developers at NVIDIA going back a few years while more recently Intel's open-source developers have been on it too with Icelake Gen11 graphics supporting HDR.

Since the Intel Cascade Lake launch in early April, the platform we've been using for our Xeon Platinum 8280 Linux/BSD testing has been the Gigabyte S451-3R0 Storage Server. Now having tested this Gigabyte server on a number of different Linux distributions as well as the BSDs and in an assortment of software configurations, we're quite confident in its abilities for those needing an Intel Xeon Scalable server platform that can accommodate a great deal of drives.

ClearFog was the name for that 16-core mini-ITX workstation development board/platform that we've been eager to learn more about with its $500~750 USD price point, extensive networking connections, M.2, SATA, socketed DDR4 memory support, and other features we've been long desiring to see out of an affordable yet powerful ARM workstation. It turns out that dream board is being renamed to the HoneyComb LX2K and its performance is increasingly competitive with AMD/Intel x86 enthusiast offerings...
