packages: add NVIDIA tesla 470 driver
This commit adds the NVIDIA tesla 470 driver. The drivers are subpackages of `kmod-5.10-nvidia`, since we don't want to have a spec file per driver type per driver version. The spec file for `kmod-5.10-nvidia` holds the drivers that are compatible with the 5.10 kernel. New spec files should be added for newer kernel and driver versions. The `kmod-5.10-nvidia` package provides a tmpfilesd conf file to create the lib modules directory where the kernel modules will be created. Each subpackage installs the libraries and binaries underneath `%{_cross_bindir}/nvidia/<type>` and `%{_cross_libdir}/nvidia/<type>` respectively to prevent collisions while building the subpackages. Kernel module objects are installed in `%{_cross_datadir}/nvidia/<type>/modules`, so that `driverdog` can compile them at runtime. Each subpackage provides a drop-in configuration file for containerd, that sets the `NVIDIA_PATH` environment variable. This environment variable must be set to the directory that contains the NVIDIA userland tools, which will be mounted on the containers by `libnvidia-container`. The environment variable is set for containerd, since `libnvidia-container` is called by the runtime to set up the containers. Signed-off-by: Arnaldo Garcia Rincon <[email protected]>
