IPC

When the endpoints of a stream reside in separate processes, IPC blocks are used to bridge the gaps. They are created in pairs, with a source IPC block in the upstream process and a destination IPC block in the downstream process. The communication must first be established by the application using NvSciIpc, and then the channel endpoints are passed to the two IPC blocks. They take ownership of the channel and use it to coordinate the exchange of requirements and resources and signal the availability of packets.

There are two types of IPC pairs available, depending on whether the upstream and downstream portions share memory.
