Member Function Documentation

bool Minor::LSQ::DcachePort::isSnooping ( ) const
inlineoverrideprotectedvirtual

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.

void Minor::LSQ::DcachePort::recvFunctionalSnoop ( PacketPtr  pkt)
inlineoverrideprotectedvirtual

Receive a functional snoop request packet from the slave port.

Reimplemented from MasterPort.

void Minor::LSQ::DcachePort::recvReqRetry ( )

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.
