[Bug 293362] graphics/nvidia-drm-kmod: No devices on 15.0

(In reply to Martin Cracauer from comment #50)
RTX 5xxx (Blackwell generation of architectures) is known NOT to work without
GSP firmware loaded (you would recall a bunch of posts at forums).

So not sure it can happen or not, but if somehow missingly fallen back NOT to
load GSP firmwares on RTX 5090, it could cause problems.

OTOH, RTX 2080 Ti is at Turing generation of architectures, thus, would work
with or without GSP firmware to be loaded.

So switching hw.nvidia.registry.EnableGpuFirmware=1 instead of 17 for RTX5090
could help.
It would cause errors on auto-loading GSP firmware in situations for uncertain
fallback happenes on value 17.

Note that Turing generation of GPUs uses different firmware module as newer
ones.
nvidia_gsp_tu10x_fw.ko for Turing and nvidia_gsp_ga10x_fw.ko for newer.
