Because of https://gitlab.archlinux.org/archlinux/packaging/packages/nvidia-utils/-/commit/4fe55fc13e8bb00a839ae09c4566974e1633cece `/dev/nvidia-uvm` and `/dev/nvidia-uvm-tools` are not there anymore, and I have to create them manually in order for cuda to work. (In the general cases, cuInit will create those files, but if the application is sandboxed, it won't be able to). Other distros create /dev/nvdia-uvm, and it was also the case of archlinux until last month. Please consider creating those file devices again.
