Longtime open-source developer Mike Blumenkrantz who has been an Enlightenment developer for many years and was working for Samsung's Open-Source Group prior to its demise jumped into the open-source Linux graphics world this year. While being unemployed he began hacking on the Zink Gallium3D code that allows generic OpenGL acceleration over the Vulkan API. He quickly got the code to the point of OpenGL 4.6 support and quite compelling performance compared to where Zink was at earlier this year. Now it turns out he will continue with his Linux graphics adventures thanks to funding from Valve...

While in 2021 we might begin to see PipeWire replacing PulseAudio by default at least on bleeding-edge distributions like Fedora, for now PulseAudio still is the dominant sound server used by desktop Linux distributions. Rolling out today is PulseAudio 14.0...

Last week we delivered AMD Radeon RX 6800 / RX 6800 XT Linux benchmarks and the performance was great both for Linux gaming as well as the OpenCL compute performance. But for as good as those Big Navi numbers were on the open-source Linux graphics driver stack, they are now even better.

GNU Guix 1.2 is out today as both an update to the cross-platform package manager as well as the Guix System Linux distribution...

Intel held a virtual event last week to basically plead their case that AMD Ryzen laptops are coming up short on battery-powered performance compared to their own offerings. It was all Windows focused, but at least given their emphasis now on battery performance gave me another opportunity to prod over the lackluster state of Intel DPTF support on Linux with it not being pleasant out-of-the-box and one of the few areas encumbered by blobs or lack of public documentation...

While NVIDIA has supported its own vendor-specific Vulkan ray-tracing extension on Windows and Linux since the GeForce RTX GPUs originally debuted, they are moving quick to support the Khronos ray-tracing extensions for Vulkan given the industry adoption and games coming to market likely opting for using the KHR version...
