AMD Sends In More "Arcturus" GPU Code For Linux 5.5
Along with Intel sending in their last feature pull to DRM-Next for Linux 5.5, AMD has done the same in sending their lingering AMDGPU feature work for queuing ahead of the upcoming Linux 5.5 merge window.
Notable to this latest AMDGPU pull, which is one of several for Linux 5.5, is more "Arcturus" code. Arcturus as a refresher is a yet-to-launch AMD compute accelerator based on Vega. There has been Linux driver patches for Arcturus for the past number of months and we know it's focused on compute/video acceleration without any 3D block working. Arcturus has yet to be formally introduced by AMD but perhaps at this month's SC19 Supercomputing conference it will get a formal introduction.

Samsung, Red Hat to Work on Linux Drivers for Future Tech
The metaverse is expected to uproot system design as we know it, and Samsung is one of many hardware vendors re-imagining data center infrastructure in preparation for a parallel 3D world.
Samsung is working on new memory technologies that provide faster bandwidth inside hardware for data to travel between CPUs, storage and other computing resources. The company also announced it was partnering with Red Hat to ensure these technologies have Linux compatibility.
