AMDVLK Still Hasn't Yet Adopted FreeSync Support

While the AMDGPU kernel driver has shipped with the long-awaited FreeSync support since the Linux 5.0 release earlier this year and was quickly wired up for the RadeonSI Gallium3D OpenGL driver in Mesa 19.0 while the recent Mesa 19.1 update brought FreeSync for the RADV Vulkan driver, AMDVLK as AMD’s official open-source Vulkan driver isn’t yet supporting this variable rate refresh technology…

Linux 5.3 Could Finally See FSGSBASE – Performance Improvements Back To Ivybridge

The FSGSBASE instruction set has been present on Intel processors going back to Ivy Bridge processors and while there have been Linux kernel patches for this feature going on for years, it looks like with the Linux 5.3 kernel cycle is this support for merging. Making us eager for this support is the prospect of better performance, especially for context switching workloads that already have been suffering as a result of recent CPU mitigations…

Developers Devising Plan To Ship Newer NVIDIA Drivers On Ubuntu Stable Releases

Currently NVIDIA’s packaged drivers on Ubuntu can get a bit stale on Ubuntu stable releases since they aren’t updated in-step with the latest driver releases. But a new stable release update (SRU) policy/exception similar to the Firefox approach is being made for Ubuntu so that new releases will end up working their way into currently supported Ubuntu series…
