Member Function Documentation

BaseMasterPort & X86ISA::Walker::getMasterPort ( const std::string &  if_name,
PortID  idx = InvalidPortID 
)
virtual

Get a master port with a given name and index.

This is used at binding time and returns a reference to a protocol-agnostic base master port.

Parameters
if_namePort name
idxIndex in the case of a VectorPort
Returns
A reference to the given port
