Simple overview:
- NFU server -- "adjacent" to IBP depot.
- NFU Op -- lightweight program, written in C, or Java, depending on server.
- NFU client -- launches nfuOps and exchanges data with it.
- Two types of data exchange:
- 1. variable exchange
- IBP_VAL_[IN, OUT, INOUT]
- variable/values exchanged directly between nfu client and nfu Op
- 2. IBP Cap handling
- IBP_REF_[RD, WR, RDWR]
- E.G. _RD: client sends readCap to server, NFU server provides nfuOp a pointer to mmap of the allocation
- nfuOp does not receive readCap string
