Intel Begins Preparing Linux Graphics Driver Support For Xe HP As "Gen12.5" - Phoronix
Xe HP is Intel's discrete GPU aiming to compete against the latest-generation AMD and NVIDIA compute accelerators. Xe HP isn't scheduled to reach general availability until well into 2021 while now as they begin ramping up their sampling of Xe HP to potential customers, the Linux open-source driver support is preparing to roll-out.
While Xe HP is about scaling up Intel Xe Graphics (Gen12), the Xe HP driver support is introducing it as a new "Gen12.5" target rather than just "Gen12" that is used by Tiger Lake / Rocket Lake / Xe LP.

NVIDIA Is Working On DMA-BUF Passing That Should Help Improve Their Wayland Support
NVIDIA is working on allowing their proprietary driver to support passing buffers as DMA-BUF. In turn this should allow for better supporting their proprietary driver on Wayland compared to the EGLStreams mess.
A Phoronix reader tipped us off to NVIDIA developer comments last month in response to a KDE EGLStreams bug. A bug report was opened regarding that restarting the compositing breaks the EGLStreams back-end for KDE's KWin.

Mesa Now 2~5x Faster For SPECViewPerf Following OpenGL Optimizations - Phoronix
Well known open-source AMD Linux graphics driver developer Marek Olšák has just merged one of his largest set of optimizations in recent times: 2~5x faster performance for SPECViewPerf.
SPECViewPerf is the common industry benchmark for measuring graphics performance for professional applications with benchmark viewsets from 3ds Max, CATIA, Maya, Solidworks, Siemens NX, and other programs. The performance when using Mesa drivers have been lagging but now thanks to common Mesa infrastructure improvements by Mesa, the performance is wildly improved.

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. |
