Member Function Documentation

bool AtomicSimpleCPU::AtomicCPUDPort::isSnooping ( ) const
inlinevirtual

Determine if this master port is snooping or not.

The default implementation returns false and thus tells the neighbour we are not snooping. Any master port that wants to receive snoop requests (e.g. a cache connected to a bus) has to override this function.

Returns
true if the port should be considered a snooper

Reimplemented from MasterPort.
