For read request the nvme driver populates the payload with source information. For write request the driver converts it to nvme copy command using the source information in the payload and submits to the device. current design only supports single source range. This design is courtesy Mikulas Patocka's token based copy trace event support for nvme_copy_cmd. Set the device copy limits to queue limits.
