Some FreeBSD Users Are Still Running Into Random Lock-Ups With Ryzen

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.

Intel OpenGL vs. Vulkan Performance With Mesa 18.0

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.

Linux Gaming For Older/Lower-End Graphics Cards In 2018

A request came in this week to look at how low-end and older graphics cards are performing with current generation Linux games on OpenGL and Vulkan. With ten older/lower-end NVIDIA GeForce and AMD Radeon graphics cards, here is a look at their performance with a variety of native Linux games atop Ubuntu using the latest Radeon and NVIDIA drivers.

Wine 3.0 Development By The Numbers

With yesterday's successful launch of Wine 3.0 I was curious how the past year of development on Wine compared to years prior, etc. Here are some Wine development statistics.

Experimental KPTI Support For x86 32-bit Linux

For the Kernel Page Table Isolation (KPTI) support currently within the Linux kernel for addressing the Meltdown CPU vulnerability it's currently limited to 64-bit on the x86 side, but for the unfortunate souls still running x86 32-bit operating systems, SUSE is working on such support.

R600g "Soft" FP64 Shows Signs Of Life, Enabling Older GPUs To Have OpenGL 4 In 2018

Most pre-GCN AMD graphics cards are still limited to OpenGL 3.3 support at this time due to not supporting FP64. Only the HD 5800/6900 series on R600g currently have real double-precision floating-point support working right now so at present they are on OpenGL 4.3 rather than 3.3, but those other generations may be catching up soon thanks to the "soft" FP64 code.

16-Way Graphics Card Comparison With Radeon On ROCm, NVIDIA With Initial 2018 Linux Drivers

Towards the end of December AMD quietly released ROCm 1.7.60 as the newest version of their Radeon Open Compute stack complete with their maturing OpenCL implementation. With the improvements there plus NVIDIA recently introducing their 390 Linux driver series (390.12 Beta currently), I ran some fresh Linux OpenCL GPU compute benchmarks on a variety of AMD and NVIDIA graphics cards for those curious how the current performance stacks up.

R600 Gallium3D Gets Some Last Minute Improvements In Mesa 18.0

These days when Dave Airlie isn't busy managing the DRM subsystem or hacking on the RADV Vulkan driver, he's been spending a fair amount of time on some OpenGL improvements to the aging R600 Gallium3D driver. That's happened again and he's landed some more improvements just ahead of the imminent Mesa 18.0 feature freeze.

Open-Source HDCP Support Gets Extended To More Platforms

With the Linux 4.17 kernel (not the upcoming 4.16 cycle) there is likely to be added initial HDCP support to Intel's Direct Rendering Manager driver. Ahead of that this High-bandwidth Digital Content Protection support continues getting improved upon.
