Member Function Documentation

void RubyPort::MemMasterPort::recvRangeChange ( )
inlineprotectedvirtual

Called to receive an address range change from the peer slave port.

The default implementation ignores the change and does nothing. Override this function in a derived class if the owner needs to be aware of the address ranges, e.g. in an interconnect component like a bus.

Reimplemented from MasterPort.

Definition at line 71 of file RubyPort.hh.

bool RubyPort::MemMasterPort::recvTimingResp ( PacketPtr  pkt)
protectedvirtual

Receive a timing response from the slave port.

Implements MasterPort.

Definition at line 184 of file RubyPort.cc.
