This functionality is -/// useful when the developer knows when and where a buffer is going to be -/// accessed. It allows the data movement to happen sooner than if the -/// Intel(R) Coprocessor Offload Infrastructure (Intel(R) COI) -/// runtime tried to manage the buffer placement itself. The advantage of -/// this API is that the developer knows much more about their own -/// application's data access patterns and can therefore optimize the data -/// access to be much more efficient than the Intel(R)Coprocessor Offload -/// Infrastructure (Intel(R) COI) runtime. Using this API may yield better -/// memory utilization, lower latency and overall improved workload -/// throughput. -/// This API does respect implicit dependencies for buffer read/write hazards. -/// For example, if the buffer is being written in one COIPROCESS and the user -/// requests the buffer be placed in another COIPROCESS then this API will wait -/// for the first access to complete before moving the buffer. -/// This API is not required for program correctness. It is intended solely -/// for advanced Intel(R) Coprocessor Offload Infrastructure (Intel(R) COI) -/// developers who wish to fine tune their application performance -/// Cases where "a change in state" is an error condition the change just gets -/// ignored without any error.

We can do the transition checks only at the time -/// when the actual state change happens (which is something in future). -/// Currently there is no way to report an error from something that happens in -/// future and that is why such state transitions are nop.
