I was thinking about the behavior of functional accesses. Currently in gdb
we can change the value of a program variable. Does that mean the
underlying processor supports functional accesses? If yes, then we should
already have some knowledge about what is expected from functional
accesses.

Yes, that is correct. The RubyPort::M5Port::recvFunctional() function is where
we need to add the new support.

Subject: [m5-dev] Functional Access support in Ruby
Brad,
Here is my understanding of the current state of functional accesses in gem5.
As of now, all functional accesses are forwarded to the PhysicalMemory's
MemoryPort. Instead, we would like to add
recvFunctional() function to M5Port of the RubyPort, and attach this port as
peer instead of the PhysicalMemory.
