Thank you Lars :-) I just switched from GTX1060 to RTX5070 and CUDA
does not work here (yet).

I am on 14.2-RELEASE AMD64, tested with nvidia-driver(-devel):
550.127.05, 570.153.02, 570.169, 575.64, 575.64.03.

For RTX5000 line a GSP Firmware is necessary to be loaded with
/boot/loader.conf in order to have Xorg working. Tomoaki Aoki (CC)
helps me with testing x11/nvidia-driver-devel even updated port to
latest code released by Nvidia (575.64.03), but the problem seems to
be in that new GSP firmware. For now I am working on the latest
nvidia-driver-devel and all desktop apps works fine, there is just no
CUDA/OpenCL. Below is the bug report with some more details:

https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=287895

Also there was a report of problems with OpenGL / Vulkan on RTX5090
series and confirmation RTX5070 is some unlucky guy that still needs
some work (as compared to RTX5060):

Thanks :-)
