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 Bye, Alexander. -- http://www.Leidinger.net Alexander_at_Leidinger.net: PGP 0x8F31830F9F2772BF http://www.FreeBSD.org netchild_at_FreeBSD.org : PGP 0x8F31830F9F2772BF
