Member Function Documentation

bool AddrMapper::MapperMasterPort::isSnooping ( ) const
inlineprotectedvirtual

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.

Definition at line 141 of file addr_mapper.hh.

References AddrMapper::isSnooping(), and mapper.

Tick AddrMapper::MapperMasterPort::recvAtomicSnoop ( PacketPtr  pkt)
inlineprotectedvirtual

Receive an atomic snoop request packet from the slave port.

Reimplemented from MasterPort.

Definition at line 121 of file addr_mapper.hh.

References mapper, and AddrMapper::recvAtomicSnoop().

void AddrMapper::MapperMasterPort::recvFunctionalSnoop ( PacketPtr  pkt)
inlineprotectedvirtual

Receive a functional snoop request packet from the slave port.

Reimplemented from MasterPort.

Definition at line 116 of file addr_mapper.hh.

References mapper, and AddrMapper::recvFunctionalSnoop().

void AddrMapper::MapperMasterPort::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 136 of file addr_mapper.hh.

References mapper, and AddrMapper::recvRangeChange().

void AddrMapper::MapperMasterPort::recvReqRetry ( )
inlineprotectedvirtual

Called by the slave port if sendTimingReq was called on this master port (causing recvTimingReq to be called on the slave port) and was unsuccesful.

Implements MasterPort.

bool AddrMapper::MapperMasterPort::recvTimingResp ( PacketPtr  pkt)
inlineprotectedvirtual

Receive a timing response from the slave port.

Implements MasterPort.

void AddrMapper::MapperMasterPort::recvTimingSnoopReq ( PacketPtr  pkt)

Receive a timing snoop request from the slave port.
