Mesa Rolls Out Support For ARB_sample_locations
Mesa has been plumbed in to support the ARB_sample_locations OpenGL extension and is now exposed with the Nouveau NVC0 Gallium3D driver.
ARB_sample_locations was part of the "OpenGL 2015" update but hasn't made it into a released version of OpenGL, hence why it wasn't a priority for Mesa developers. But now it's been wired up within core Mesa and is currently flipped on for NVC0 in Mesa 18.2-devel.

Mesa's VirGL For OpenGL Within VMs Now Supports Tessellation Shaders
It was just days ago that the VirGL driver stack -- which is used for supporting OpenGL hardware acceleration within guest VMs that is passed onto the host's driver -- picked up FP64 support while now its latest addition is ARB_tessellation_shader support.
With the latest Mesa Git and the VirGL renderer library code is updated (as well as your host OpenGL driver supporting GL4), there is now support for tessellation shaders. The support has landed in Mesa 18.2 Git for this popular OpenGL 4.0 feature.

Samsung, Red Hat to Work on Linux Drivers for Future TechThe 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. |
