Detailed Description

This is the request port of the communication monitor.

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

Member Function Documentation

◆ isSnooping()

bool CommMonitor::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.

Definition at line 156 of file comm_monitor.hh.

References CommMonitor::isSnooping(), and mon.

◆ recvAtomicSnoop()

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

inlineprotectedvirtual

Receive an atomic snoop request packet from our peer.

Implements AtomicRequestProtocol.

Definition at line 136 of file comm_monitor.hh.

References mon, and CommMonitor::recvAtomicSnoop().

◆ recvFunctionalSnoop()

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

inlineprotectedvirtual

Receive a functional snoop request packet from the peer.

Implements FunctionalRequestProtocol.

Definition at line 131 of file comm_monitor.hh.

References mon, and CommMonitor::recvFunctionalSnoop().

◆ recvRangeChange()

void CommMonitor::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.

Definition at line 151 of file comm_monitor.hh.
