I am looking at tiler_src_pad_buffer_probe in deepstream_test_3.py. It gets pad, info and u_data as arguments. In particular info has the buffer and all metadata. Among all of these pieces of data, which ones are on GPU-RAM vs main memory? Is there a way to know this?

There is a memType property in nvbufsurface https://docs.nvidia.com/metropolis/deepstream/python-api/PYTHON_API/NvDsBufsurface/NvBufSurfaceDoc.html. For meta data, it is in cpu memory.
