Mesa 19.1 To Expose EXT_gpu_shader4 Support

While it's not looking like Mesa 19.1 will end up exposing OpenGL 4.6 capabilities, it is picking up various other extensions including some prominent several year old extensions like EXT_texture_buffer_object and the decade old EXT_gpu_shader4.

NVIDIA Working On New GLX Extension To Help PRIME GPU Offloading

NVIDIA has been working on a new GLX extension to help the PRIME GPU offloading situation where multiple GPU vendors are involved and thus different OpenGL driver implementations. In particular, the proposed GLX_EXT_server_vendor_select is designed to better fit in to address PRIME GPU offloading obstacles introduced by their work on the now common GLVND OpenGL Vendor Neutral Dispatch library.

OS108 Yields NetBSD Desktop Operating System Powered By MATE

Over the past decade there's been talks on a few occasions about either spinning NetBSD as a desktop platform or offering up various desktop usability improvements to make it easier to use this BSD as a desktop operating system. In 2019 there still isn't a great desktop experience to NetBSD but the new "OS108" is seeking to improve that with a NetBSD OS paired with the MATE desktop environment.

RADV Vulkan Driver Lands FreeSync/Adaptive-Sync For Mesa 19.1

While on the kernel-side there has been FreeSync support with the AMDGPU DRM driver since Linux 5.0 and for the OpenGL driver with RadeonSI there has been this functionality in Mesa 19.0 when paired with a supported kernel, the Mesa Radeon Vulkan driver has missed out on this action until now. But landing just in time for the Mesa 19.1 feature freeze is now the FreeSync/Adaptive-Sync enablement for RADV.

Intel Iris Gallium3D Picks Up More Game Performance Optimizations For Mesa 19.1

There is just one week to go until the Mesa 19.1 feature freeze and branching for this next quarterly feature update to these open-source OpenGL/Vulkan Linux drivers. Notable this round is the introduction of the Intel "Iris" Gallium3D driver for supporting Broadwell graphics and newer atop this next-gen OpenGL driver ahead of next year's Xe Graphics dGPU launch. With days to go until the Mesa 19.1 feature freeze, more performance optimizations have landed.

Scientific Linux 6/7 Will Remain Supported But The Distribution Is Ending

For those wanting a community-supported, free version in effect of Red Hat Enterprise Linux, the two options have been CentOS with its close relation (and employment) by Red Hat or Scientific Linux that has been maintained Fermilab, CERN, and other research labs. Moving forward, however, these labs are going to be adopting CentOS 8 and they will not be developing a new version of Scientific Linux based on the upcoming RHEL8.

Dropped Linux Kernel Drivers Occasionally See Revival - FDOMAIN Gets Second Chance

When drivers get dropped from the Linux kernel it's generally due to hardware being no one cares about anymore that hasn't been produced in many years and the code often falls into disrepair to the point that the only logical way forward is dropping the driver. That happened last year to the "FDOMAIN" driver but as does happen every so often (albeit rare) thanks to the code being still obtainable through Git and the nature of open-source, interested parties can step up and revive the code.
