I have spent some time this weekend trying out the DRM-Next code slated for inclusion in Linux 4.16 when its merge window opens next week. The DRM-Next state of the AMDGPU driver appears to be in good shape, at least for the RX 580 and RX Vega cards used for my initial testing...

Linux 4.15 isn't happening today as planned: there's simply too much recent activity and some bugs known to be outstanding. As such, we're up to the ninth weekly release candidate...

For those wondering how the Intel (U)HD Graphics compare for games and other graphical benchmarks between desktop environments in 2018, here are some fresh benchmarks using GNOME Shell on X.Org/Wayland, KDE Plasma 5, Xfce, Unity 7, and LXDE.

While Linux has been playing happily with Ryzen CPUs as long as you weren't affected by the performance marginality problem where you had to swap out for a newer CPU (and Threadripper and EPYC CPUs have been running splendid in all of my testing with not having any worries), it seems the BSDs (at least FreeBSD) are still having some quirks to address...

Linux 4.15 will hopefully be released later today and that will kick off the start of the Linux 4.16 kernel merge window. Here's some of what is coming to this next kernel cycle...

Given the very strong Vulkan vs. OpenGL performance in the recent low-end/older Linux gaming GPU tests with discrete graphics cards, I was curious to run some benchmarks seeing the current state of Intel's open-source OpenGL vs. Vulkan performance. With the Mesa 18.0 release to be branched soon, it was a good time seeing how the Intel i965 OpenGL and ANV Vulkan drivers compare.
