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)...

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...
