As far as the session interfaces are concerned, the framework is very intricately designed (hats off). Connection->Client->Capability->Session. If I want to call a function defined by the session interface, one has to include the <session_name>/connection.h and make a call which then calls the Rpc_functionName. My question is this: Where is the body of such functions defined? Is there a framework that dictates where the body of the function goes?

More specifically, this doubt came up when exploring the Attached_io_mem_dataspace which contains a function called dataspace(). 

Recently, my friend Aditya posted this and it gave the error 'No RM attachment', which is found in the function print_page_fault defined in util.h. My assertion is that a component that uses the MMIO class initlaiised with this dataspace().local_addr() rather than the physical address itself. 

Long story short, what could have caused this page fault?

Thanks in advance,

Meenakshi.
