Detailed Description

This is the request port of the communication monitor.

All recv functions call a function in MemCheckerMonitor, where the send function of the response port is called. Besides this, these functions can also perform actions for capturing statistics.

Member Function Documentation

◆ isSnooping()

bool MemCheckerMonitor::MonitorRequestPort::isSnooping ( ) const

inlineprotectedvirtual

Determine if this request port is snooping or not.

The default implementation returns false and thus tells the neighbour we are not snooping. Any request 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 RequestPort.

◆ recvAtomicSnoop()

Tick MemCheckerMonitor::MonitorRequestPort::recvAtomicSnoop ( PacketPtr pkt )

inlineprotectedvirtual

Receive an atomic snoop request packet from our peer.

Implements AtomicRequestProtocol.

Definition at line 107 of file mem_checker_monitor.hh.

References mon, and MemCheckerMonitor::recvAtomicSnoop().

◆ recvFunctionalSnoop()

void MemCheckerMonitor::MonitorRequestPort::recvFunctionalSnoop ( PacketPtr pkt )

inlineprotectedvirtual

Receive a functional snoop request packet from the peer.

Implements FunctionalRequestProtocol.

Definition at line 102 of file mem_checker_monitor.hh.

References mon, and MemCheckerMonitor::recvFunctionalSnoop().

◆ recvRangeChange()

void MemCheckerMonitor::MonitorRequestPort::recvRangeChange ( )

inlineprotectedvirtual

Called to receive an address range change from the peer response 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 RequestPort.
