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.

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.
