CUDA

CUDA supports the import of an NvSciBufObj into CUDA as CUDA external memory of type NvSciBuf. Once imported, use CUDA API to get a CUDA pointer/array from the imported memory object, which can be passed to CUDA kernels. Applications must query NvSciBufObj for the attributes required to fill descriptors, which are passed as parameters to the import/map APIs.

If the NvSciBuf object imported into CUDA is also mapped by other drivers, then the application must use CUDA external semaphore APIs described here as appropriate barriers to maintain coherence between CUDA and the other drivers.
