This won't work for applications depending on unified memory support, but otherwise should be good enough.
Could you plesae describe a little bit more detailed what your shim does? I have the impression it maps some linux glibc symbols which are used in a NVidia library for CUDA which only exists as a linux lib to FreeBSD symbols and when some FreeBSD binary then tries to load the NVidia CUDA lib it is then using the FreeBSD libc/m/pthread.
If this is correct, what would be in your opinion the correct way to get official CUDA support? Something like the following or is more needed?
- implement nvida-uvm - implement os_lock_user_pages- submit the above to NVidia and ask for the CUDA lob to be compiled for FreeBSD
