That Dell Hardware Privacy platform support is now set to be introduced to the mainline kernel with Linux 5.14...

The Linux 5.14 kernel this summer is going to bring a reworked user-space API for Intel's DG1 graphics card and their future discrete graphics offerings. This change to the Intel kernel graphics driver's user-space API, which is currently flagged as "broken" until it has been proven sufficiently capable for user-space needs and stable, is principally needed for handling of device local memory (dedicated vRAM)...

Earlier this month were benchmarks looking at Windows 10 vs. Ubuntu 21.04 on an AMD Ryzen 9 5900X desktop to which Ubuntu came out roughly 8% faster than the Microsoft OS on average. But what about the difference for HEDT systems? Given the more radical performance difference we have seen in the past with Windows vs. Linux for Threadripper systems, here are some recently conducted benchmarks on that front with the 64-core Threadripper 3990X.

Over the past year developers from Igalia, Collabora, and others have been involved in bringing up support for the OpenGL EXT_external_objects extension within the Intel open-source drivers.

Last month with the Radeon Software for Linux 21.10 driver there was finally Vulkan ray-tracing support added to that proprietary Vulkan driver component, the first time that Vulkan ray-tracing has been available on Linux for any AMD Radeon 6000 series graphics card across the multiple driver options. Last month I posted some initial Vulkan ray-tracing AMD vs. NVIDIA Linux benchmarks while questions were raised how well the driver performs with NVIDIA's Quake II RTX port. Here are some initial benchmarks for those wondering...
