GB10x and GB20x have distinct hardware architecture bytes (0x1a and 0x1b respectively), but I only had a single Architecture::Blackwell = 0x1b. That means GB100 and GB102 would fail probe with ENODEV. I'm splitting it into Architecture::BlackwellGB10x = 0x1a and Architecture::BlackwellGB20x = 0x1b, which also lines up with how Open RM (ARCHITECTURE_GB100 / ARCHITECTURE_GB200) and Nouveau (GB10x / GB20x) handle it. Will be fixed in v9. Thanks, John thanks, -- John Hubbard
